Air currents surged.

Gusts of cool wind swept in from the windows around the hall, causing Li Cheng Yi's clothes to flutter slightly.

At this moment, he looked up at the scene on the ceiling.

On a horizontal beam there, he could vaguely see a small box about the size of a palm.

"As expected... even as he was dying, he didn't forget to point out clues to his people. But why, why did he have to make it so secretive? Could it be that besides people from their organization, there are other lurkers here? Or perhaps, this method of escape is only allowed for a fixed number of people? Too many people won't work?"

Guesses flashed through Li Cheng Yi's mind.

He estimated the height of the beam, bent slightly, and jumped up.

*Chi!*

At that instant.

Purple particle streams suddenly sprayed out from the nozzles on his arms and the back of his calves. A large number of particle streams formed a beautiful light and shadow like tulle in mid-air, propelling him to float lightly.

~

The roof had a sunroom, and underneath were some withered vines.

Standing on the edge of the roof, he looked down.

"This propellant particle stream can actually freely adjust direction and intensity according to my thoughts."

He landed on the roof.

Above his head, a huge crack slowly opened in the rock wall of the sky.

"Li En's clues naturally need to be investigated, but I must find a way out before taking action."

Slowly, in the red light, a two-meter-tall silver-gray humanoid figure slowly rose out.

Li Cheng Yi had been hiding in the corner of the sunroom, and waited for seven minutes until the outer realm giant eye disappeared before slowly walking out.

Eighty meters.

Each shield had a different symbol. Seven bursts of radiance exploded in succession.

Putting away the drawing, Li Cheng Yi took one last look at the corpse and turned to leave the exit.

The piercing alarm sounded again.

"I need to look down from a high place and directly find the building with the octagonal frame on the roof at the fastest speed."

The monster was bending over, stuffing a pale female corpse into its stomach.

Just as he was about to land, he quickly sprayed particle streams, rolled on the spot, and with a dull thud, the impact precisely sent him into the sunroom door.

Standing in front of the octagonal frame, he placed the stone in his hand into the empty space in the stone pillar.

Li Cheng Yi looked up.

Its head and chest were covered with dense, honeycomb-like dark red glowing holes, like a brazier scorched red, leaving messy air holes, constantly emitting cold air.

One block, two blocks, three blocks, four blocks... *Pfft!*

*Hui Shan! Bang!*

The top was painted with smooth strokes, like a comic strip with instructions.

The heavy weight of the sword, hundreds of pounds, although bearable, affected my speed, so I chose to hold one sword with both hands, rather than wielding two.

*Ka-cha. Bang!*

On the edge of the roof directly opposite the sunroom stood a silver-gray octagonal frame.

*Ka-cha.*

"It's going smoothly, I found the key point right away... Next, I need to find the Mud Monster. And the density is still increasing."

"If this drawing is real, then this key may be related to opening the intangible door..."

Most of its body turned into white smoke, floating into the air, and a white stone fell to the ground with a clang, rolling a few times before stopping.

Streams of golden light, like spikes, pierced out from the back of its body. The intense purification and scorching heat caused its entire body to constantly evaporate large patches of white mist.

Li Cheng Yi carefully took out the drawing and unfolded it. Then he quietly rushed out, lightly jumping on the street.

Just then.

There was something on the roof; looking down from above, one could see it clearly at a glance.

Returning to the octagonal frame, I carefully observed it.

In the middle of all the patterns, a space was deliberately left, seemingly specifically for placing something.

The shoulders seemed to have two square boxes installed, constantly emitting the clicking sound of chains and gears turning inside.

While stuffing, it made gurgling noises.

The giant eye slowly rotated, gazing down at everything in the city.

*Chi!!*

It was an office building about ten stories high.

The frame was about eight meters high, with a stone pillar standing in the center. The pillar was mixed with some messy, indistinguishable lines and carvings.

Not long after.

Inside the crack, was that incomparably enormous, terrifying giant eye covering the entire city.

"Who are you?" Li Cheng Yi tried to communicate with the other party. At the same time, he gripped the green electric greatsword in his hand.

Adjusting his figure, he slowly floated to the edge of the beam, reached out and took the white box placed on top, and then landed.

The light was marked with smooth dotted lines; its color was unknown.

Finally, a door opened, with a rounded arch, also releasing light. In the center of the door, a key-like graphic was drawn.

The stone pillar suddenly rotated automatically. Not long after.

Li Cheng Yi first eliminated the surrounding low buildings one by one, and then, as the altitude increased, inspected the higher buildings one by one.

"The clues Xiao Mao gave me are already enough; next, as long as I find the roof with the octagonal frame, everything will be easily solved."

Li Cheng Yi looked down.

The shapes of the frames were basically the same as those drawn in the drawing!

*Chi!*

*Ka-cha.*

The density of Dark City's dead corner was greater than he thought, so getting the key as soon as possible and finding the intangible door was the best.

With a soft sound.

"Want to come together?" I said in a low voice.

I squinted and scanned it, making sure nothing was discovered before continuing to fly to the roof.

The two were extremely similar!

Then, the ground below it suddenly lit up with a patch of red light, like an iron plate baked red by flames.

"Found it!" Li Cheng Yi's heart leaped with joy, and he quickly changed direction, flying towards there.

Purple particle streams sprayed out rapidly, and after a few seconds, he landed lightly, standing on the street.

The Mud Monster's entire body was like a biscuit, shattered, turned into fine powder, and collapsed to the ground.

*Bang!*

The striped cat was still meowing, and the meowing made Li Cheng Yi pause.

Finding the Mud Monster at the fastest speed was his only thought at this time.

The giant eye appeared for a full seven minutes before slowly closing, disappearing into the rock wall.

Seventy meters.

The box was opened, and inside was a folded, yellowed drawing.

Deliberately using his hand to touch the golden light, the resulting huge thrust carried him to accelerate instantly, slamming down towards the roof like a bullet.

Li Cheng Yi bent down and picked up the stone.

After all, the strength and toughness of this sword are very poor.

Seven purple particle streams sprayed out from behind me, propelling me to fly into the air.

He reacted quickly in mid-air, changing direction with his arms downward. With great difficulty, he avoided crashing headfirst into the ceiling.

I looked back.

The howling wind grew louder and louder, and the influence of the air currents grew greater and greater, forcing him to repeatedly adjust the spraying direction and intensity of the particle streams to avoid being blown off course by the wind.

Abandoned and dilapidated streets were dark and silent.

Suddenly stomping on the ground, his whole person shot out like a rocket, starting to move rapidly along the street.

"Awesome! I didn't expect Zi Teng Hua to still have this function after three evolutions! Even if it doesn't enhance all-around qualities, this ability alone is worth it."

I glanced around, and in just a few seconds, I had already risen to a height of ten meters.

*Hui Shan x4!*

After rolling a few times, he gradually adapted to the propellant adjustments of his arms and calves.

Li Cheng Yi paused and didn't speak again.

The eight eight-cornered shields slowly revolved around the humanoid figure, and from time to time, red fluorescent symbols lit up on the shield surfaces.

Seventy meters.

The adaptive capacity of the Shadow Dragon bloodline allowed me to quickly adapt to this light and floating flight mode in just a few minutes.

Very quickly, subtle screams floated out from the corner, followed by pieces of ash-like white things flying up and flying towards it.

Someone was holding a white stone and placing it in an octagonal support on a roof, then stepping back and standing far away.

The overall frame and stone pillar were silver-gray, while the carved patterns were dark red.

The striped cat looked up at me and didn't move; it rubbed its head against the corpse's trouser legs again, then lay down, resting against the corpse like that.

This kind of scene made him involuntarily think of the situation when he summoned the secret sword before.

The sudden auxiliary force made Li Cheng Yi a little flustered.

Suddenly, a bright color appeared in Li Cheng Yi's vision.

"It seems there are also new dead corner people coming in here."

Without a sound, the stone pillar slowly sank into the red light and disappeared in the blink of an eye.

*Wu ~~~ Ka-cha.*

I also heard the screams just now.

Many of the surrounding buildings were already prostrate under his feet, but there were still a few tall buildings where only their waists could be seen.

If I guessed correctly, the stones here should be the same kind as those in the Mud Monster's body.

Walking to the door, I carefully observed the inside. I didn't see the Armored Mud Monster.

Suddenly, something below made a subtle noise.

Eighty meters!

As for the white stone before, that made me involuntarily think of the stone I found on the Mud Monster before.

A dazzling golden light suddenly exploded from behind it.

Body lightly flying, Yin Xu Yi felt as if he was being held up by the wind, floating upwards lightly.

I returned to the top of the office building.

The omnipotent *Hui Shan* instantly ambushed and penetrated its entire body.

Li Cheng Yi's expression changed, turning around with his back facing, and a dazzling golden light exploded behind him instantly.

After a while, the octagonal support radiated a faint light.

The silver-gray humanoid figure's arms hung down, and sharp eight-bladed claws popped out from each wrist.

Seventy meters.

Sure enough, flipping over the back of the drawing, it was drawn there, with the white stone being taken out of a Mud Monster's body.

Looking at the half of the female corpse that was left, I slowly returned.

If all of this can still be considered within the scope of technology, then the eight gray octagonal shields floating around the humanoid figure became completely incomprehensible anomalous phenomena.

There were no lights in the buildings, incomparably dark, only death.

It was quiet below, nothing there.

Determining the location here, Yin Xu Yi jumped down from the edge of the building.

Finally, on the sidewalk of the first block, I discovered a Mud Monster.

It was a narrow humanoid figure covered in silver-gray heavy armor.

"The meaning is, the key is in this open door?" Yin Xu Yi understood roughly.
