For Igor's theory, Feng Bujue couldn't accept it immediately, but he understood parts of it.

After pondering for a moment, Igor continued, "Okay, assuming I really have become the... super soldier you mentioned, that still doesn't explain why those devils didn't take me away too, does it?"

"Oh, so... you don't know the reason?" Feng Bujue mused.

"Of course I don't," Igor immediately replied.

"Hmm..." Feng Bujue thought for several seconds, then said, "Then, according to your observation, did those devils... do anything unusual to you?" He paused for half a second and added, "I mean, when you only had one head."

"This..." Igor recalled, "Now that you mention it..." He did notice something, "They... all seemed to not see me."

"Can't see you?" Feng Bujue repeated this key word with a questioning tone.

"Yeah." Igor nodded. "That is to say... when they looked in my direction, their gaze never focused on me, as if I and the bed frame behind me were just background..."

"Oh..." Hearing this, Feng Bujue immediately had a deduction, "You say... could this be related to 'blood'?"

"Blood?" Igor revealed a puzzled expression.

"You said earlier that the researcher who was torn in two didn't shed a drop of blood under some strange effect," Feng Bujue continued. "So I was thinking, the abilities of those 'devils' might have some connection to human blood..."

"You mean..." Igor wasn't stupid, he belatedly responded, "Because there's no normal blood in my body anymore, so..."

"So in their eyes..." Feng Bujue took over his sentence and said, "You're like an 'invisible shadow'."

Igor thought about it and chuckled twice, "Heh... heh heh... if that's the case, it's actually pretty good."

"It is pretty good." As Feng Bujue spoke, he picked up the syringe and several empty blood bags for drawing blood, and walked towards the container holding the vno-9 liquid by the bed.

"Uh..." Igor seemed to have guessed what the other party was going to do, "Mr. Feng, you wouldn't be thinking of injecting that into yourself, would you?"

"No, I don't have that intention." Unexpectedly, Brother Jue gave a negative answer. "There's only one lab log here, meaning... you're the only known test subject; without other data to support it, I can't be sure whether this drug will have the same effect on me as it does on you." His tone of narration was objective and indifferent, as if he was describing something unrelated to himself. "Your body can adapt to this drug, but that doesn't mean I can. What's more... even you, this 'successful example', went through several near-death crises during the experiment. Therefore, unless absolutely necessary, I'm not going to take this risk."

Igor understood only bits and pieces, but he gathered that Brother Jue wasn't planning to inject himself, so he asked, "Then what are you going to..."

"I just want to carry some with me in case of emergencies," Feng Bujue replied. "If I'm forced into a dead end, I don't mind giving myself three hundred milliliters directly to take a gamble."

"That... would cause blood vessels to burst, wouldn't it..." Even if Igor didn't have much medical common sense, he knew that injecting such a large dose of liquid had to be done slowly or in stages.

"You don't have to worry about that." Feng Bujue's calm attitude made him seem like a desperate criminal, "I have my own ways."

Seeing his nonchalant appearance, Igor didn't say much else. He simply changed the subject and asked, "By the way, what were you writing those past few hours?"

"A novel." Feng Bujue responded without thinking as he busied himself with what he was doing.

"Ah?" Igor's first reaction was—did I hear wrong?

"I am a novelist." Feng Bujue knew that the other party didn't understand, so he explained again.

"Even if you're a novelist and suddenly struck by inspiration, you wouldn't be rushing to write in a place like this, would you?" Igor continued to ask.

"It's not that I want to write that I write," Feng Bujue smiled helplessly, "I'm just affected by 'something'."

Then, Brother Jue explained the existence and principles of ***-1011 to Igor, and gave detailed explanations as much as possible in a way that the other party could understand.

At first, Igor didn't quite believe such a thing, but then he thought... he'd had his head cut off today, seen devils, what else couldn't he believe?

So, he generally accepted that setting...

...

More than ten minutes later, Feng Bujue and Igor were both ready.

The two took all the necessary things and armed themselves... then, they walked out of the operating room together.

Brother Jue knew that Igor, this NPC, was a very powerful helper, and the difficulty of "getting this helper" was also quite high.

Don't look at Feng Bujue as if he hasn't encountered any particularly large obstacles along the way, as if he's casually and naturally completed the script to this point, but in reality... if someone else were playing, they might have died more than ten times already.

Even putting aside all the settings that could "scare people offline", there were at least five or more visible "death flags".

First, experiment room number one...

In this room, if you delay for more than twenty minutes for any reason, the barefoot guy will break in, and the result will undoubtedly be—death.

If you attack the mirror in the room, the "person" in the room behind the mirror will try to lure the barefoot guy over in advance, and then the player will—die.

Next, after the player leaves experiment room number one, if they stop in front of the statue room door, try to open that door, and the time exceeds five minutes, then... the barefoot guy will appear from the other end of the corridor at a time when some player doesn't have time to enter the operating room. At this time, if the player doesn't react in time, then—it's death again.

And in that situation, the only effective "reaction" is... that is, to escape back to experiment room number one, close the door again, and under the premise of keeping the lights off, run to the corner farthest from the door, squat down, and "cover" your body with Igor's entire body.

Only by strictly implementing the above actions will the result of the barefoot guy not being able to "see the player" after entering the room be triggered, otherwise, you know—death is just a word, I've said it for the fourth time.

Then, there is a super obvious instant death event in the operating room... those who do not hide under the bed in time—die.

In addition, if the player runs in the direction where the barefoot guy appeared when he walks towards experiment room number one, it will also trigger a death flag...

Finally, one more thing... as Feng Bujue predicted, if the player deliberately triggers ***-1011 again after knowing its characteristics, the system will definitely determine it as passive gaming. It's not just death at that point, you'll also bear various penalties and be kicked out of the script.

In short, don't look at Feng Bujue playing so easily, in reality... he's been walking on a tightrope. It's just that he almost never takes the wrong step or goes astray, so to others, it seems that he hasn't faced much danger.

As for Igor, this "helper", he should be considered a hidden reward-level existence... Generally speaking, players either ignore that head or give him a quick death, and then continue to explore. After all, there are few people like Feng Bujue who would move the body over and try to "reconnect the head"... and the excellence of the reward after this move is successful is also obvious to all.

After Igor's body is reorganized, Brother Jue is equivalent to getting a summon that's like an "invisible barrier" in front of monsters, and it's one that has unlimited duration and comes with recovery abilities. Letting him do reconnaissance work is more than suitable, and even if he steps on something like a landmine, there's a high probability that he can survive.

...

"Then, as agreed, you'll scout the way." After walking out of the operating room, Feng Bujue said this to Igor.

"Okay... okay." Although Igor also knew that it was more appropriate for him to scout the way, he wasn't a fearless person like Brother Jue after all, and in this environment, he would still be a little apprehensive.

"Don't be nervous, remember... you're very strong now." Feng Bujue was also very clear that even though his body had mutated, Igor's mentality was still that of an ordinary person, and he needed to be encouraged more. "Physiologically, you're almost immortal; when you encounter devils, they can't see you anyway; and if you encounter any emergencies, I'll be behind you to give you instructions; in short, you can rest assured."

"Hmm..." Igor nodded in response after hearing this, and then, he started walking... leading the way.

In fact, Feng Bujue had already told Igor a lot of similar things while packing his equipment. If it wasn't for Brother Jue patiently doing ideological work, it was unknown whether Igor would dare to walk out of that operating room...

After this period of contact, Brother Jue had also seen that—"fear of supernatural things" was the biggest weakness on this NPC; in the subsequent scripts, he had to take this factor into account, otherwise he might get tricked.

Of course, Igor, this helper, is already a great weapon from a tactical point of view, so it's normal to have some flaws. If the system had set Igor's personality to be "a fearless materialist, a staunch fighter who takes liberating all of humanity as his responsibility", then the following script would have become "Soviet Captain takes you on a tour of Nightmare Dungeons".

Clang—

"Wh... what's that sound?"

Dozens of seconds later, Igor had just led Brother Jue out more than twenty meters, when a strange noise came from the corner ahead, scaring him to stop immediately.

"It sounds like..." Feng Bujue calmly continued, "Some kind of gate sound?"

He was just guessing, but... he was right.

A dozen seconds later, the two came to that corner. They poked their heads out and saw that the corridor ahead had been closed off by a metal gate that had closed from both the top and bottom directions.

"This... there's no way out?" Igor turned his head and looked at Brother Jue and asked.

"I see..." Feng Bujue muttered thoughtfully and turned back.

"Eh? What do you see? What do you know again?" Igor also quickly followed him back.

At this moment, Brother Jue understood two things. The first thing—when the barefoot guy was walking towards experiment room number one, if he had chosen to escape in this direction, then the sound of the iron gate closing would have lured the barefoot guy back, and at that time, the player who had their path blocked would have been blocked by the barefoot guy in the corridor.

As for the second thing...

"There should be a pressure-sensitive device here." Feng Bujue returned to the place where he had heard the "clang" sound just now, and said, looking down at the ground.

"What... device?" Igor was obviously a person with limited education, and he didn't understand some words.

"Simply put, it's the kind of mechanism that gets triggered after being stepped on." As Feng Bujue spoke, he was already trying to find the pressure-sensitive point.

"Oh..." Igor responded, and then lowered his head, helping Brother Jue step here and there on the ground.

However, the two worked there for a long time, but it was still in vain.

"Hmm..." Feng Bujue stopped and rethought for a moment, "It's not the kind of mechanism that can be opened by stepping on it again..." At this time, he thought of the barefoot guy again, "Speaking of... I didn't hear the sound of the gate when that monster came and went... the difference between us and him is..."

Thinking of this, a flash of inspiration struck Brother Jue's mind.

"Heh... okay." After thinking of the answer, he laughed, and then walked three or four meters in the direction of the operating room, and then said to Igor, "Igor, come over here."

"Ah?" Igor was stunned for a moment, and then walked towards Brother Jue, "What's wrong? Have you found the location of the mechanism?"

"Yes, I've found it." Before Feng Bujue's voice could fade away, a relatively slow, continuous sound was heard from the corner.

"Eh? Really?" Igor heard this and prepared to turn back forward, but...

Clang—

He had just turned around and taken two steps when he heard the sound of the gate closing again.

"Damn it... is there more than one switch?" Igor looked down at the bottom of his feet and said.

"No, there's only one." Feng Bujue shook his head and said, "Starting from where you're standing now, the entire corridor ahead... is a complete 'pressure-sensitive area'."

"Huh?" Igor used an interjection to express that he didn't understand.

"Go back to where I am first." Feng Bujue continued.

Igor shrugged and walked back again. When he walked to Brother Jue's side, the sound of the gate slowly opening also came again.

"Let me put it this way..." Feng Bujue pointed to the front, turned his head and said to Igor, "When an object with a weight reaching a certain level presses on any part of the corridor ahead, the gate will close."
