"Damn! What is that!"

Seeing the scrap metal trash can behind him, Big Face Cat, whose nerves had just relaxed a little, immediately became alert and jumped aside.

"Trash can robot."

Lin Xian helplessly looked at the old robot whose model was called VV.

Before, he thought he had tripped and broken it, so it mistook him for garbage and wouldn't let go.

But now it seemed he had wronged it.

It was already broken and malfunctioning.

Or rather... it was too old and outdated, and probably had been eliminated long ago.

At least in this city, Lin Xian had never seen such a backward and dilapidated robot.

Outside the square, the streets were full of technology, with various robots performing fancy acrobatics. Many were so fast that he couldn't even see them clearly.

He had also seen truly advanced garbage disposal robots, which were truly incomprehensible future technology. Wherever they went, there wasn't a single piece of garbage, and the ground was as clean as if it had been licked.

In contrast...

This idiot robot that only knew how to lock people's ankles was far too backward in both style and intelligence.

It was hard to imagine.

That such a backward and dilapidated robot would exist on the high platform of the Zhao Yingjun statue, revered and loved by the people of Sky City, was simply out of place.

What made Lin Xian even more puzzled was...

If its program was really disordered, malfunctioning, and would treat any human it saw as garbage.

Then why didn't the mechanical clamps grab Big Face Cat and A Zhuang?

Just now, the three of them were clearly standing together, but this thing went straight for him, its tracks spinning, accurately locking onto his ankle.

"Garbage! Garbage! Garbage detected!"

Big Face Cat pointed at Lin Xian:

"It's calling you garbage."

"It's pretty strange..." Lin Xian admitted.

He tried to summarize all the clues about this trash can robot:

First of all, it was too dilapidated to be near the Zhao Yingjun statue; since Zhao Yingjun had painstakingly built this square and prohibited flying, it meant that she also valued this place very much. From this point of view... this trash can robot must have been specially placed here by her.

Since it was specially placed here, it must have been deliberately left for him, right?

But right now, besides being annoying and disruptive, did this idiot robot have any other use?

Secondly, the full name of this trash can robot was Miniature Garbage Disposal Robot VV; VV, this was a name that was inextricably linked to him. Connecting it in this way made him even more certain that the purpose of this idiot robot appearing here must be related to him.

Finally, and most importantly, the programming of this trash can robot didn't seem to recognize other people as garbage, it was purely infatuated with him and would only lock his ankles.

In summary.

Lin Xian believed that this trash can robot was definitely a clue left for him by Zhao Yingjun.

But...

What exactly was this clue?

In this section, Lin Xian felt that everyone around him seemed to be riddlers, and seemed to be changing their methods to make him guess riddles, which was really giving him a headache.

"Forget it, let's ignore it for today."

Lin Xian pried the clamp of the trash can robot open from his ankle, placed it far away, and then took Big Face Cat and A Zhuang off the high platform and into the square.

The sparse crowd here, and their peculiar clothes, gave Big Face Cat and A Zhuang a feast for their eyes, shocking them at the development of technology.

And when they really walked out of the square and came to the side of the road...

They truly understood what a real dimensional reduction strike was.

A naked-eye 3D neon city, layers of fish-like traffic, all kinds of robots big and small, and skyscrapers that disappeared into the clouds.

Naturally, it also included the carefree and happy pedestrians on the street.

"Pah!"

Big Face Cat spat on the ground in a fit of pique:

"Damn it, we're suffering down there, and they're enjoying themselves up here!"

Immediately—

An unbelievable scene appeared!

Just as the glob of phlegm spat out by Big Face Cat was about to land, it was suddenly captured by some inexplicable force, spun 270 degrees in the air, and flew rapidly towards the sky!

The three of them followed the glob of phlegm with their eyes, turning to the upper part of the road.

They saw...

There, a garbage truck the size of a van was floating and flying, currently moving at high speed, and Big Face Cat's glob of phlegm was like a flying bird, chasing the garbage van and flying straight into the garbage bin with a whoosh.

Lin Xian and Big Face Cat looked at each other, speechless.

A Zhuang slapped his thigh hard:

"That's what you call a garbage can robot! It's much more advanced than that piece of junk just now!"

After saying that, as if testing, A Zhuang took out a ball of toilet paper from his pocket and threw it directly on the ground.

In less than three seconds.

Whoosh—

The ball of toilet paper flew up diagonally in a graceful curve, like a fish being caught, and was sucked into the garbage truck a dozen meters above their heads.

The shape of this garbage truck was the same as the one that flew away just now. Because it was flying directly above the three of them, Lin Xian looked up and saw the model identification mark on the bottom of the garbage truck—

Floating Model Garbage Disposal Robot A37

In this way...

A37, that was the model of this garbage truck robot, right?

This model was relatively intuitive and easy to understand.

A should be the abbreviation of the specific model, and the 37 behind it was either the size or the number of updates and iterations.

Thinking back to that idiot robot VV...

What kind of model was that?

Unclear.

"Stop playing around, let's get going."

Lin Xian stopped Big Face Cat, who was about to blow his nose on the ground, and pulled the two of them towards the street ahead.

He had already asked the pedestrians in the park and found out that the Rhein Museum was not far from here, only one block away on foot.

That was good, saving them the trouble of taking a vehicle.

Lin Xian was increasingly convinced that the clue left for him by Zhao Yingjun, and the secret in the mirror mentioned by Huang Que, should be in this Rhein Museum.

The three of them walked on the road without attracting much attention.

In this free Sky City, there were all kinds of styles of dress on the road. In comparison, the three of them were ordinary and low-key enough.

Soon, the three of them arrived at the location of the Rhein Museum.

Except for the main road in front of the museum, there wasn't much traffic in other places around. After all, the museum wasn't open to the public at night, and there was no point in coming here to play.

Looking from a distance, it could be seen that the Rhein Museum covered a very large area. There was not only a clear height difference between the front and rear halls, but also a road in between.

However...

The current problem wasn't how to enter the rear hall. The three of them came to the gate of the museum's wall and found that the gate was tightly closed.

It was still the electronic gate that was common in this Sky City, like the gate under the Zhao Yingjun statue. They couldn't see any buttons or door lock components, and had no idea how to open it.

Currently, without going through this electronic gate, there was no way to enter the museum's courtyard, and therefore no way to enter the exhibition halls inside.

"Let's use a magic treasure."

Big Face Cat muttered, and took out something mud-gray and taped up from behind his waist.

"Damn."

Lin Xian looked at this long-lost magic treasure:

"C4? Why did you think of bringing this thing skydiving?"

"I don't feel safe without bringing C4 when I go out." Big Face Cat smiled cheekily, showing his professionalism:

"But we can't bomb the gate. Generally speaking, the gate is the strongest and most difficult place to blast, and it's likely to have an alarm device. We'll go around to the side and bomb the side wall... I see that the outer walls of this museum are basically built of stone, and C4 can easily blast through it."

"But... Brother Face."

Lin Xian dissuaded him:

"Using C4 outdoors is different from using C4 indoors. In an open-air environment, such a loud noise, light, and dust... it's impossible not to attract attention. My purpose in sneaking into the museum isn't to steal things. I have to take a good look at the things inside. So if it attracts the police and patrols, tonight will be in vain."

"Then what should we do?"

Big Face Cat stuffed the C4 back into his waistband:

"The only entrance and exit to the museum's wall is this steel electronic gate. You can't open it, and you don't want to use C4 to blow up the side wall. You definitely can't get in."

Lin Xian thought for a while with his chin in his hand, looking up and down at the outer wall of the museum.

The outside was relatively smooth, but the height was limited, only a little more than 4 meters high.

He also glanced at the height of Big Face Cat and A Zhuang.

There was no way around it.

He would have to use the same trick again.

"Let's build a human ladder." Lin Xian looked at Big Face Cat and A Zhuang:

"You two support the outer wall and build a human ladder for me. After I step on you and jump in, you go to the pharmacy to scavenge for medicine. Once you find the medicine, find a place to skydive down. Don't worry about me."

"What nonsense are you talking about!"

Big Face Cat cursed:

"You brought us in here. Since we agreed to help you enter the museum, we'll help you to the end. How could we leave you alone? I can't do such unrighteous and immoral things."

Seeing that Big Face Cat was still so loyal, Lin Xian smiled and patted his shoulder:

"I appreciate your kindness, but don't worry about me. I'm also carrying a parachute, and I have my own escape route, which is much more familiar than yours. I've already told you the location of the pharmacy. After building the human ladder, go and carry out your mission... The people below are still waiting for you."

Seeing A Zhuang also leaning over, Lin Xian nodded to him as well:

"Don't worry, we'll see you below. Our fate is very strong, and no time or destiny can break us apart..."

"Believe me, farewell for now."

In the end, Big Face Cat and A Zhuang were persuaded.

After the three of them bumped fists, Big Face Cat braced himself against the museum's outer wall, and A Zhuang climbed onto his back, stepping on his shoulders, and built the human ladder diagonally to a height of more than three meters.

Well.

This height was about right.

For a parkour expert like Lin Xian, it was easy to step on the human ladder and cross the last meter or so, much easier than climbing over the garbage dump before.

"Thank you, brother."

Big Face Cat tensed his muscles and supported the wall, turning his head to look at Lin Xian, who was preparing to run:

"You must come back!"

Lin Xian smiled slightly and bent down:

"Of course, I still have to return the purse to Ningning."

Whoosh!

Lin Xian got up and accelerated like a cheetah, grabbing Big Face Cat and A Zhuang and flying onto A Zhuang's shoulders in a few steps, and then a powerful jump and wall grab! Successfully climbing over the museum's outer wall!

Thud!!

The heavy landing sound... inside was a hard stone ground, shaking Lin Xian's legs until they ached. Fortunately, the landing posture was very professional and resolved a lot of the impact, and after rubbing it, it was fine.

Two quick whistles came from outside the wall, indicating that Big Face Cat and the others were retreating. Lin Xian also stood up and began to look around the environment.

It had to be said that this Sky City had probably been peaceful for too long and was used to it. Everywhere felt completely unsecure. Even these gates were completely defenseless against villains.

But this also showed that life here was really good, with no worries about food and clothing, unlimited energy, and naturally a very low crime rate; coupled with being located at an altitude of more than 2,000 meters, and an air defense network covering 10,000 meters of sky... it was completely an impossible fortress to invade, so naturally not many people cared about security issues.

Could it be...

Was this also within Zhao Yingjun's plan? Was everything for his convenience?

Lin Xian wasn't sure.

But at least based on his current experience, Rhein Sky City was much easier than New Donghai City.

He was currently in the museum's open-air courtyard. Besides the greenery and some artistic buildings, there was nothing of value.

To view the history of Rhein Sky City and enter Zhao Yingjun's personal exhibition hall, he had to find a way to enter the internal exhibition hall.

Lin Xian walked to the long staircase and walked up.

The museum was empty at night, very quiet. Walking on this long, sloping staircase, he inexplicably felt a sense of temporal weight.

Because he felt that he didn't belong here, but was walking on the history of this city.

What would be in the exhibition hall?

What would be in Zhao Yingjun's personal exhibition hall?

Lin Xian couldn't wait.

However.

"Sigh... another electronic gate."

Lin Xian looked at the gate of the exhibition hall speechlessly.

Like the museum's open-air gate and the gate under the Zhao Yingjun statue, they were all steel gates with no possibility of cracking.

What should he do?

This was an indoor hall, and there was no possibility of climbing over the wall.

"Is there a window that was forgotten to be closed for me to climb through? I should have asked for Big Face Cat's C4 bomb just now."

Lin Xian walked around for a long time, but couldn't find a window that could be opened. Even the windows that he could reach were very few due to the height.

"What should I do..." Lin Xian scratched his head.

Click!

A familiar clamp sound!

Lin Xian looked at his ankle in surprise. It was the familiar rusty clamp.

"Garbage! Garbage! Garbage detected!"

Looking back...

It was haunting him...

It was still the familiar trash can shape, the familiar green light in its eyes, the familiar trash can robot VV!

"Big brother..."

This time Lin Xian was really speechless.

How obsessed was this guy with him as garbage? Did he chase him all the way from Zhao Yingjun's statue to the museum?

Lin Xian inexplicably thought of the science fiction film Terminator 2 directed by James Cameron. The trash can's relentless pursuit was comparable to the T-1000 liquid robot in it.

"Huh? That's not right?"

Lin Xian squinted his eyes, looking at the dilapidated robot that was tightly locking his ankle and calling him garbage.

Something was wrong...

In the last dream, he had discovered something wrong with this robot—

Zhao Yingjun's statue high platform and the square were separated and blocked by a tall steel electronic gate.

So Lin Xian and the others had to climb over the wall to get down to enter the square.

But!

The last time he dreamed, Lin Xian threw this trash can robot down from the high platform, and not long after, it directly climbed back onto the high platform.

This was very strange. How did it get up?

The only passage was that steel electronic gate.

Could it open that electronic gate?

At that time, Lin Xian didn't think so much, and only thought that there might be other small passages for these garbage robots to enter and exit.

But now.

The walls of this museum were also completely closed, and similarly a steel electronic gate separated the inside and outside, but this idiot robot had chased after him unimpeded.

It couldn't climb over the wall, the only way to enter the museum was to open the steel electronic gate!

"Could it be..."

In an instant, Lin Xian was enlightened, and looked down at the idiot robot that was locking his ankle.

Suddenly.

He felt that the rusty thing was somewhat handsome.

He forcibly pried open the clamp that was holding his ankle, picked up this idiot robot, and looked at it:

"Could it be that you are a..."

"Door-opening robot?"

The more Lin Xian thought about it, the more he felt like it was the case.

Otherwise, there was no way to explain these strange situations, unless this robot had very high permissions and could open all the electronic doors in this Sky City!

Thinking of it being the only "living thing" around Zhao Yingjun's statue... thinking of everything that Zhao Yingjun had carefully designed and linked together...

This broken robot might not be a key.

"I'll know if I try."

Lin Xian ran quickly towards the gate of the museum exhibition hall, holding the trash can robot.

As soon as he put the robot on the ground...

Click!

The familiar mechanical clamp locked his ankle.

"Garbage! Garbage! Garbage detected!"

But then!

Beep beep! Squeak——————

After a mechanical chime, the steel electronic gate that was just tightly closed opened directly from the middle and slowly moved to both sides!

At the same time, the lights in the internal exhibition hall lit up row by row in an orderly manner, as if bowing in welcome, and the entire internal exhibition hall instantly lit up, inviting Lin Xian, this VIP, to enter.

"I'll go..."

Lin Xian had never enjoyed this kind of treatment before.

He stroked the trash lid of the trash can:

"So you really are a door-opening robot, the key that Zhao Yingjun left for me!"

At this moment.

Lin Xian understood Zhao Yingjun's good intentions.

She was so meticulous, like a nanny, leaving him an invincible permission, a golden finger key that could open any electronic door in the entire Sky City.

If he had discovered this earlier, why would he need to go through so much trouble now? He could just carry the trash can and open the way.

Although this trash can was somewhat handsome, it was still too uncomfortable to have it locked on his ankle, and it wasn't conducive to walking. So Lin Xian simply picked it up and held it in his arms, walking into this brightly lit museum.

The museum exhibition hall was very large, and there were many things on display.

This place must usually be able to accommodate many tourists, but tonight, this museum was only open for him.

Lin Xian strolled around inside.

Many historical relics related to Rhein Sky City were on display here.

For example...

The design drawings of Sky City.

The introduction electronic screen next to it wrote that Rhein Sky City was designed and built by the Rhein Company led by Zhao Yingjun. All the details and layout were personally handled by Zhao Yingjun, just to make this first Sky City in human history perfect enough.

And this epoch-making creation exhausted all the wealth accumulated by the Rhein Group over hundreds of years. Finally, not long after Rhein Sky City was launched, Rhein Company went bankrupt and closed down.

But humanity still thanked Rhein Company and Zhao Yingjun for their contributions to this city. So even though Rhein Company was gone, the name Rhein was still the most unique commemorative totem of this Sky City.

"Why is there no trace of my existence at all? Wasn't Rhein Company established by me?"

This was also a doubt that Lin Xian had always had.

How was the history here completely different from the real history?

It was as if Zhao Yingjun was the founder of Rhein Company. There was nothing about him, and even his existence seemed to have been erased.

What had happened in these hundreds of years?

Lin Xian continued to walk inside and discovered many interesting things:

The first-generation model of the cold fusion engine,

The first-generation city robot,

And so on

And so on... many things he could understand and couldn't understand.

Behind each thing, there was a story that seemed amazing.

Lin Xian understood.

The things displayed in this museum were basically some old objects and relics related to Rhein Sky City. It was true that they were very commemorative, but for him, they couldn't completely connect a period of history, and couldn't answer his doubts about the historical development of these hundreds of years.

"I should hurry to the rear hall and take a look at Zhao Yingjun's personal exhibition hall."

Although the pharmacy clerk had told him before that Zhao Yingjun's personal exhibition hall wasn't open every day.

Because the exhibition inside was in the form of a projection telling Zhao Yingjun's life, it was only exhibited regularly at specific times and required advance reservation.

But he had a door-opening robot, what was there to be afraid of... as long as there was a door, he could get in.

Lin Xian continued to walk towards the middle of the exhibition hall.

When he reached the very center of the exhibition hall, he found a huge object placed in the middle.

The size of this exhibit was several stories high, and it looked like a complex combination of countless cutting-edge computers. Judging from its exhibition position, this must be the most valuable and valuable exhibit of all.

Was this a computer?

It looked square and upright, with many incomprehensible devices.

Lin Xian walked around it and found the electronic notice board explaining the exhibit on the front of this huge device. The name of this exhibit was written on it—

Rhein Sky City First-Generation Intelligent Central Hub VV

"VV?"

Lin Xian unconsciously said the name. Why was it VV again?

He was about to get closer to observe it.

However!

When the trash can robot in his arms heard him say the two words VV, its eyes instantly alternated between red and green!

After a burst of flashing.

It slowly turned its head, its green eyes staring at Lin Xian at close range:

"Please enter the password!"

"What?" Lin Xian didn't react for a moment.

He put the robot in his arms on the ground.

Click!

The trash can robot habitually clamped Lin Xian's ankle with its mechanical clamp, but didn't say the phrase "garbage detected". It was still staring at Lin Xian with its green eyes:

"Please enter the password!"
