Actually, Gu Yi had noticed this long ago.

Patients rarely spoke to each other, or perhaps they had already spoken but he couldn't hear them.

Only when he communicated with medical staff and personnel could he do so without any hindrance.

Was this simply because he was a "special test subject"?

Or perhaps, the role he played was not human at all, but rather a local indigenous like the staff?

The door opened, and the nurse glanced at the two people in the ward.

"It's almost dinner time. Xu Nian, can you go by yourself?"

Xu Nian tilted his head and thought for a moment before nodding.

Xu Nian could understand what the doctor said, but he couldn't speak in front of the nurse.

"In that case, Gu Yi, you go and take him to the cafeteria."

"Okay."

Gu Yi borrowed a wheelchair from the nurse's station and pushed Xu Nian to the cafeteria.

Xu Nian was very grateful and excitedly nodded and thanked Gu Yi repeatedly.

Gu Yi patted Xu Nian's shoulder to calm his emotions.

After dinner, Gu Yi went to the toilet.

Just as he was about to engage in another round of deduction, he suddenly heard a voice from the stall on his left.

"Brother, do you have any paper over there? Can you give me one?"

"Just a moment."

Gu Yi's heart pounded, and he turned around to tear off a piece of toilet paper and handed it under the partition.

"Thank you."

Gu Yi heard the sound of the person fastening his belt and then the sound of releasing the belt - he had sat back on the toilet again.

Puff!

Gu Yi frowned and covered his nose.

"Are you having diarrhea?"

"Well, there's nothing I can do." The person said, "I almost have diarrhea every day. I'm someone who can't eat meat. Whenever I eat it, I get diarrhea. But the hospital rules require me to order one meat dish and one vegetable dish, which makes my daily life unbearable."

"Why does the cafeteria have such strange rules?"

"Who knows? The damn dean is a perfectionist. Buying meals is like solving math problems every time, it's really annoying. Brother, can you give me another piece of paper?"

"Well, here you go."

Gu Yi handed the paper over.

After pondering for a moment, Gu Yi decided to chat with the person next door for a while, but he was worried that he might inadvertently violate some rules, so he decided to use his talent.

(Deduction begins!)

(You: Are you Dr. Li?)

(Dr. Li: How did you know?)

(You: You check on me every day, and I remember your voice.)

(Dr. Li: Yeah, I was wondering why your voice sounded so familiar.)

(You: Dr. Li, do you know "Monster Siege"?)

(Dr. Li: Where did you hear that term?)

(You: I heard it from the shop owner in the square.)

(Dr. Li: Let's talk about something else.)

(You nod silently, apparently, the hospital staff also have their own set of rules and can't discuss "Monster Siege" too much.)

(You: Why can't I understand what other patients are saying?)

(Dr. Li: That's because they are ill, but your condition is milder.)

(You: Actually, I want to know what kind of illness we have exactly.)

(Dr. Li: Didn't I already tell you? It's a mental illness.)

(You: If it's a mental illness, why does Xu Nian have so many surgical scars on his body? If this is a mental hospital, why do you have the qualifications for surgeries?)

(Dr. Li's tone becomes noticeably colder.)

(Dr. Li: Gu Yi, it seems your condition has worsened, you need a higher dosage.)

(You: Dr. Li, I understand your difficulties. You just need to tell me yes or no. If you can't speak, then knock on the partition once for yes and twice for no.)

(Dr. Li: What do you mean?)

(You: You're using unconventional treatment methods on patients, performing surgical procedures even though it's a mental illness, such as amputations. Is it because of the influence of the rules?)

(Dr. Li remains silent for a while, then knocks once on the partition.)

(As you expected, doctors, like the shop owner, are also controlled by the rules. They are not unapproachable or unexploitable.)

(However, the rules only restrict them from "speaking," but not from "communicating.")

(You: You can't directly talk about these things, or else you'll die too, right?)

(Dr. Li knocks once.)

(You: You also don't want to be trapped in this hospital, do you?)

(Dr. Li knocks once on the partition.)

(You: Do you know how to leave the hospital?)

(Dr. Li knocks twice.)

(You ponder for a while and ask a very bold question.)

(You: In your eyes, am I the same as the other patients?)

(Dr. Li knocks twice.)

(You: In your eyes, am I one of your kind?)

(Dr. Li knocks once, then twice.)

(Yes, and no.)

(You clench your fists as you find answers to some inexplicable aspects.)

(Any treatment the hospital performed on you was meant to turn you into a monster, to become a monster just like them.)

(However, in your eyes, the doctors and nurses were merely humans wearing masks.)

(If you didn't violate the rules, these people wouldn't turn into monsters.)

(The words "I am human" have repeatedly appeared in the bloody hints of "I".)

(It was a clear hint.)

(If you want to successfully pass through, you have to maintain your humanity and constantly remind yourself that you are human.)

(However, the current situation is not optimistic.)

(In the eyes of the doctors, you have already become different from other humans, and you can only communicate with the doctors but not the patients.)

(The power of the "unspeakable" has already started to infect your cognitive system.)

(Dr. Li: I've talked enough, I have to go.)

(Dr. Li left the restroom, releasing a fart as he departed.)

(You terminate the deduction.)

Gu Yi sat on the toilet, waiting silently.

Dr. Li was setting off fireworks next door, borrowing toilet paper from Gu Yi four times in a row.

By the time Dr. Li finished using the toilet, dinner time had already ended. Gu Yi gave up on the opportunity to speculate in the toilet and returned to the ward.

Just like the first day, Gu Yi woke up at midnight and continued exploring the hospital using his talent.

(Deduction begins!)

(You escape from the ward with ease.)

(You have become familiar with the night watch doctor's patrol route from previous experiences.)

(While exploring at night, as long as you don't use the access card, it's unlikely the security department would catch you.)

(You go directly to the third floor.)

(You arrive at the dean's office using the ventilation duct.)

(You turn on the computer and try entering the dean's and the dean's daughter's birthdates as passwords, but it still didn't unlock the computer.)

(You feel frustrated.)

(Suddenly, you hear footsteps outside the door.)

(Quickly, you unplug the computer and hide behind the bookshelf.)
