(You grit your teeth and persevere.)

(With great effort, you manage to drive that voice out of your mind.)

(Black fur starts growing on your legs.)

(Unspeakable's power becomes incredibly strong here.)

(You put the bird-beak mask back on.)

(The process of your transformation slows down, but cannot be completely stopped.)

(You feel that it's because you haven't found more crucial clues or items, which is why exploring the second basement level is so difficult.)

(You continue to search and explore here.)

(You hear someone humming a song.)

(You hide in a corner and observe carefully.)

(It turns out to be a person wearing a kangaroo mask who enters the storage room. They open their pants, pull out a bunch of fresh ingredients from their crotch, and place them on the cabinet.)

(You feel nauseous.)

(Apparently, the hospital's food supplies are brought in this way by the kangaroo people.)

(You secretly follow them.)

(The kangaroo person approaches an elevator, which they can open without using an access card.)

(Once the kangaroo person leaves, you rush up to the elevator.)

(You press the button in the elevator.)

(The elevator can go to the first floor, basement, and the second basement.)

(You press the button for the first floor.)

(The elevator opens to the back kitchen of the cafeteria.)

(It's lunchtime, and there's only one chef peeling potatoes.)

(Chef: Why are you here?)

(You dare not speak, as any attempt to do so would result in barking like a dog.)

(Chef: Why aren't you speaking?)

(You lower your head and walk away.)

(The chef stops you and removes your mask.)

(Chef: We have an infected individual here!)

(Doctors arrive in the back kitchen, and they grab hold of you.)

(You are taken to the emergency room.)

(The doctors use a chainsaw on you, severing your limbs.)

(Doctor: No hope, send him to the crematorium.)

(Everything goes black before your eyes.)

(You're dead.)

(Deduction ends.)

Gu Yi opened his eyes again, sitting on the toilet, and carefully contemplating everything that just happened.

He took out a pen and paper, jotting down the new clues he obtained.

1. The hospital has not only a Level -1 [basement] but also a Level -2 [second basement]. The deeper one goes, the stronger the unspeakable's power becomes. The bird mask possesses some ability to resist mental contamination. However, relying solely on the bird mask is insufficient for exploring the second basement.

2. There are methods other than Room 0 to access the hospital's underground floors. The kitchen's elevator and the crematorium can be used without an access card. The secure methods to enter the back kitchen and the crematorium are currently unknown.

3. There is ample evidence to prove that this is a research institute rather than a hospital, where they conduct modifications on humans. The native inhabitants of the hospital, including medical staff, employees, and security personnel, are all monsters.

4. In the archive room, "Monster Seige" is just an ordinary movie. It only reveals its eerie side when one wears the bird mask. It can assist in accessing the hospital's second basement.

But perhaps that is not the true purpose of "Monster Seige."

The main characters in "Monster Seige" are humans, which indicates that the movie is intended for humans, not the natives.

The monsters in "Monster Seige" develop hostility towards the medical staff in the hospital, which is why the monsters start chasing after the person once they wear the mask.

Therefore, "Monster Seige" might be a tool to kill the indigenous inhabitants.

5. Using Room 0 to access the basement is not advisable. The toad must have a more significant role, and there might be more than one large spider in the hospital. I must come up with a more reasonable method to enter the underground floors.

Gu Yi didn't continue the deduction and hid all the items before heading to the cafeteria for a meal.

Sometimes it's best to be concise.

Due to his injuries not being fully healed, Gu Yi still hasn't gone to the treatment room for medical treatment. He returned to his ward, and his fellow patient, Xu Nian, was still unconscious.

Outside the window, barking dogs and honking vehicles could be heard.

Today, another group of bosses arrived at the hospital. This time, the group consists of not only the Deer-Headed Persons but also the Bull-Headed Persons, Kangaroo-Headed Persons, Elephant-Headed Persons, and Pig-Headed Persons.

Gu Yi believes that these individuals wearing different masks must have different professions and identities in the dungeon world.

"Uh..."

Xu Nian groaned.

Noticing this, Gu Yi quickly turned his head to look at his ward mate.

"What's wrong?"

"Uh..."

Xu Nian opened his mouth but didn't speak.

"Why aren't you talking?"

Xu Nian's mouth slowly moved, but Gu Yi still can't hear him speaking.

"What is it? Do you want some water?"

Gu Yi pointed to the water bottle behind him, and Xu Nian squinted and nodded.

Gu Yi poured a glass of water for Xu Nian.

Xu Nian took a sip.

Gu Yi furrowed his brows, suddenly thinking of a possibility.

—Maybe it's not that the patients in the hospital don't speak, but rather that I can't hear them speaking.

Xu Nian clearly communicated with him just now, but why couldn't he hear any sound?

Could this be related to the various experiments conducted on him by the hospital?

"Lie down and rest for a while."

"Uh..."

Xu Nian lay down obediently, staring at the ceiling in a daze.

Gu Yi returned to his own bed and suddenly felt an itch on his wrist.

He rolled up his sleeve and saw black fur growing on his wrist.

"Oh shit..."

The power of the "unspeakable" is increasing, and he had starting to undergo mutation.

If he doesn't come up with a way to clear the level quickly, he will eventually turn into a monster.

Gu Yi immediately closed his eyes and activated his talent.

(Deduction begins!)

(You spit out the key to the ward from your mouth.)

(Seeing your actions, Xu Nian opens his mouth in astonishment.)

(You make a gesture to silence Xu Nian.)

(You secretly open the door to the ward and carefully observe.)

(Taking advantage of the nurse's bewilderment, you quickly run out and hide in the toilet.)

(You put on Dr. Gui's attire.)

(Most of the doctors and nurses in the hospital are concentrated in the treatment rooms on the second floor.)

(Many unfamiliar guests, led by the Pig-Headed Person, have arrived on the second floor.)

(You blend in with the doctors' group and eavesdrop on the conversation between the Pig-Headed Person and the guests.)

(Pig-Headed Person: Welcome to Chongshan Hospital. If you want to choose **, Chongshan Hospital is your best choice.)

(The Pig-Headed Person mentioned a strange term that you couldn't understand at all.)

(You speculate that ** refers to humans.)

(Deer-Headed Person: I want to choose **.)

(Pig-Headed Person: What will you mainly use it for? To watch # or to accompany #@#?)

(Deer-Headed Person: I'm bored at home alone, so I bought one to play with.)

(Pig-Headed Person: Then I suggest you choose a female. They tend to have a gentler temperament...)

(The Pig-Headed Person uses more professional terminology and leads the first customer into the treatment room. They look through the glass at each sleeping patient.)

(You feel puzzled.)

(The Deer-Headed Person takes a stroll outside and finally chooses a female patient. He leads her out of the treatment room.)

(You secretly follow them.)

(Once the female patient steps out of the hospital building, she immediately transforms into a creature covered in black fur. She has a very gentle personality and doesn't resemble the aggressive black-furred monsters seen in the basement.)

(You successfully blend in with the Deer-Headed Person's group and squeeze onto the bus.)

(The driver of the bus is a person wearing an elephant mask. He waves at you.)

(Driver: Where's your ticket?)
