(The Dean enters the office.)

(He looks at the dust on the desk, appearing somewhat puzzled.)

(He turns his head towards the position of the bookshelf.)

(You notice that the Dean wasn't wearing a mask, and he reveals a smile.)

(Dean: I see you.)

(You are unsure whether the Dean is a friend or foe. After struggling for a moment, you decide to come out.)

(Dean: What are you doing here? Why aren't you on duty?)

(You: Nothing.)

(Dean: Is today your first day on the job? You dare to enter my office without permission?)

(You pause for a moment, realizing that you were wearing a bird beak mask, and the Dean mistook you for hospital staff.)

(You: I'm sorry.)

(Dean: It seems I need to establish some rules again.)

(The Dean takes out a pen from his chest and writes a line on a piece of paper, then stick it on the office door.)

(Suddenly, you hear a low murmur in your ear.)

(You see a black figure appear behind the Dean.)

(It is the first time you directly faced the unspeakable.)

(Dean: From now on, without my permission, no one is allowed to enter my office.)

(The power of the unspeakable is activated, forcefully pushing you out of the office.)

(The door of the office had a message written on it: "Without the Dean's permission, no one can enter the office.")

(You try turning the doorknob.)

(The doorknob is extremely hot, burning your palm.)

(Evidently, the Dean has merged with the "unspeakable," and he can use the power of the "unspeakable" to temporarily establish rules.)

(Within the hospital's boundaries, the Dean is like a god.)

(No wonder the third-floor office area was empty at night. It was because the Dean might come to the office at night and didn't want to encounter other staff members.)

(Sneaking into the office will make the Dean more vigilant and lead to the establishment of new rules, prohibiting others from entering the office.)

(Therefore, you shouldn't attempt to crack the computer password until you have 100% certainty.)

(You need to understand the Dean's movement patterns to avoid encountering him in his office.)

(Additionally, there was another Dean's office in the second basement, and you don't know if there would be any other clues there.)

(Now, you have finally found the final boss of this dungeon.)

(You feel that there is nothing else to explore at the moment.)

(You terminate the deduction.)

Gu Yi's consciousness returned to reality, and he slowly opened his eyes, taking a deep breath.

In the weird world, the unspeakable was divided into two types.

One was the "conceptual" unspeakable.

This type of unspeakable had no physical form and couldn't be defeated. It was the most challenging boss to deal with.

The other type was the unspeakable that attached itself to a physical entity, similar to the Dean in this dungeon. As long as you found their weakness and destroyed them, you could achieve a perfect completion.

Gu Yi felt relieved.

Although this dungeon was difficult, at least the final boss had a physical form. The difficulty of completing the scenario would be much lower compared to dealing with a conceptual boss.

Gu Yi felt a bit weary and closed his eyes, drifting back to sleep.

...

He woke up the next day.

Gu Yi felt an unbearable itch in his hand.

He rolled up his sleeves and saw that the black fur had already spread from his wrist to his elbow.

It was now 6 a.m., and the doctor hadn't arrived yet. He had to find a way to deal with his wrist; otherwise, he might end up being taken to the emergency room for amputation.

Gu Yi went to the ward's bathroom and used a razor to shave off the black fur on his hand.

As the black fur fell into the sink, it immediately transformed into grayish-white maggots and wriggled down the drain.

Gu Yi finally managed to shave off the black fur, but he still felt itchy.

Just a few minutes after shaving, stubble had already started to grow back.

At this rate of growth, the black fur would soon cover his entire arm, and he would undoubtedly be sent for amputation.

After a while, the doctor entered the room for rounds.

Gu Yi easily managed to deceive the doctor.

When Xu Nian saw Gu Yi spit out the pill, he was stunned.

"Hush-," Gu Yi waved his hand. "Don't tell anyone about this."

Xu Nian quickly jumped off the bed, rolled up Gu Yi's sleeves, and touched the stubble on his hand. Then he pointed at the pill in the spittoon.

"Are you saying that the pill is for treating my illness?"

Xu Nian nodded.

"But... I can't take it."

Gu Yi frowned.

At this moment, he realized the most challenging aspect of the dungeon's rules.

—The pill had to be taken.

If he didn't take the pill, he would be gradually consumed by the unspeakable and turn into a monster.

But if he took the pill, he would violate the rules of "I" and die on the spot.

Gu Yi felt that "I" was most likely a tortured soul killed by the unspeakable.

Therefore, when Gu Yi portrayed "I," he needed to experience once again the process of gradually losing his humanity.

Among the customs clearance conditions, one of the customs clearance conditions is to survive in the hospital for 30 days.

In fact, this condition was the most difficult to achieve.

Either you would accidentally trigger an instant death flag within thirty days.

Or you would be chopped into a human stick due to the outbreak of the illness.

Or before you even persist for thirty days you would be transformed into a monster covered in black fur.

Breakfast time arrived.

After finishing breakfast, Gu Yi went to the square as usual for some fresh air.

Gu Yi briefly exercised his body. Just as he stepped onto the treadmill, the Shop owner walked up to him and handed him a cigarette.

"Want one?"

"Um... thank you."

The Shop owner lit a cigarette for Gu Yi.

"It's really troublesome. My niece hasn't left yet, so I have to come here to smoke. She can't stand the smell of cigarettes."

"Hehe, she's such a lovely child."

They both took a puff of the cigarette.

During the deduction process, Gu Yi had already interacted with the Shop owner and understood his temperament.

As they chatted, the Shop owner even felt like he had met a long-lost friend.

The Shop owner pointed behind him and smiled, "Why don't you come with me?"

"What's the matter?"

"That little troublemaker is leaving the hospital today, and she specifically asked for you."

"Oh, really?"

Gu Yi blinked and followed the Shop owner.

They arrived at the backyard, where Yao Yao was squatting on the ground playing with mud.

When Yao Yao saw Gu Yi, she quickly rushed over and clung to him like a monkey.

"Big Brother Gu Yi!"

"Oh!" Gu Yi's cheeks turned red from the force. "You're so strong; you'll suffocate me like this."

"Ah, sorry."

Yao Yao quickly released Gu Yi and looked at him with an embarrassed expression.

Gu Yi squatted in front of Yao Yao, gently caressing her head. "You called me here specially. Is there something you want to tell me?"

"I came to bid you farewell. I'm leaving today, and I don't know when I'll come back. Will we be lifelong friends?"

"Of course."

"Before leaving, I want to give you something. I think you'll find it useful."

While saying that, Yao Yao took out a pair of blue work pants from under her skirt.

Gu Yi was shocked and dumbfounded.

—Those work pants were exactly the same as the ones worn by the kangaroo-headed person!
