Actually, during Gu Yi's progress, there were many small details hinting at him to explore the cafeteria.

Toto's handmade mask is a pig head, just like the chef in the cafeteria.

The password for the dean's computer is 1205.

The dean's wife's birthday is on December 5th.

When ordering food, the total price must be 12.5 yuan.

The rules state that the cafeteria is off-limits during non-meal times, which made Gu Yi keep his distance from the cafeteria and overlook the need to explore it.

However...

Not only the cafeteria but also the basement and the dean's office are restricted areas in the hospital.

But Gu Yi is still able to come and go freely, right?

As long as he has the right method, he can go anywhere.

The cafeteria restriction only applies to non-cafeteria personnel. If he wears the pig-head mask, he should be able to easily breach the restricted area, right?

With this in mind, Gu Yi's fighting spirit reignited.

Gu Yi quickly finished his meal.

The sky was getting dark.

Gu Yi couldn't wait until midnight and immediately began his deduction.

(The deduction begins!)

(You crouch by the door panel and eavesdrop for a while until everyone in the corridor heads to the treatment room. Then you quickly run out of your room.)

(You arrive at the kitchen.)

(The pig-headed chef is washing the dishes.)

(Chef: It's almost time to finish work. Why aren't you leaving?)

(You: I left something inside, I'm just looking for it.)

(You make up a random excuse, and the chef doesn't suspect anything.)

(You search the kitchen and storage room but find nothing.)

(You come to the freezer room.)

(There's a door with access control. You use the red access card to open it and slip inside.)

(The temperature in the freezer room is extremely low, and various pork, beef, and lamb meats are stored here.)

(You find nothing.)

(When you try to leave the freezer room, you realize that the door is locked.)

(You knock on the door forcefully, but no one responds.)

(The pig-headed chef after turning off all the lights has already left for the day.)

(You shiver from the cold.)

(You put on the elephant mask and struggle for a while before managing to open the door from the inside.)

(You take a sip of ginger tea to warm up.)

(Taking advantage of the empty surroundings, you continue to explore the cafeteria.)

(You enter the chef's rest area.)

(Still, you don't find any useful clues.)

(Desperately, you lie down in the rest area.)

(You realize that you can't find any breakthroughs.)

(Mentally exhausted, you act out in the kitchen.)

(You pull out your hair and remove the mask from your face.)

(You realize that you're undergoing a mutation.)

(Your vision becomes blurred, and you're about to enter a state of mental breakdown.)

(The ceiling starts dripping blood.)

(Your vision turns blood-red.)

(You notice a phantom of a woman in front of you.)

(You follow her.)

(She leads you to a warm place.)

(You fall asleep.)

(You have completely transformed into a monster.)

(You die.)

(The deduction is over!)

Gu Yi opened his eyes, gazing at the hospital ceiling, his throat tightening and lips drying up.

Immediately, his heart began to pound violently, as if his whole body was engulfed in flames.

"Calm down! Stay calm!"

Gu Yi bit his lip hard, forcing himself to regain emotional stability.

The Unspeakable's erosion had caused him to collapse directly during the deduction process.

Because he had given up hope during the deduction, the Unspeakable took advantage of the opening, turning him into a madman in the deduction and even transforming into a monster before his death.

Such mental erosion even affected Gu Yi in reality.

However, Gu Yi's resilience had long been tempered.

He forcefully resisted Unspeakable's erosion with his willpower.

"Think, what have I overlooked?"

Gu Yi pinched his nose, calming himself down.

When his mind was about to succumb, he saw an illusion, one he had never encountered before.

Could it be that the kitchen puzzle could only be solved after he transformed into a monster?

"Let's try again!"

(Backtracking begins!)

(You stand in the kitchen's rest area.)

(You take out a red pill and swallow it.)

(You transform into a monster and remove the mask, keeping it safely.)

(The ceiling starts dripping blood.)

(Figures fill your vision, but you manage to maintain your sanity.)

(You find the silhouette of the woman.)

(You follow behind the woman.)

(The surroundings constantly change until you finally arrive in an empty room.)

(The woman sits in the room, smiling silently.)

(You feel your consciousness gradually drifting away from yourself.)

(You: Who are you, exactly?)

(Woman: I am the Dean's wife. I can answer three questions for you. The first question was just now.)

(You pause for a moment.)

(You now have 15 points of mental power remaining. By utilizing the backtracking, you can backtrack three times, which means you can ask nine questions in total.)

(You: In the office of the second basement, there is a computer. What is its password?)

(Woman: I don't know.)

(You: What is the weakness of the Unspeakable?)

(Woman: When you can see through all the lies, you will be able to defeat it.)

(You: How did you die?)

(Woman: You have already asked three questions.)

(The woman kicks you out of the room.)

(You terminate the deduction!)

Gu Yi took a deep breath and analyzed the previous conversation carefully.

1. It is impossible to obtain the password from the Dean's wife.

2. The key to defeating the Unspeakable lies in "seeing through all the lies" – in other words, finding a way to break free from his own hypnotic state.

"At least it wasn't completely fruitless. Let's give it another try."

(Backtracking begins!)

(You stand in front of the woman.)

(You: How did you die? Please be specific, including the cause of death and the time.)

(Woman: I died from an illness. I had congenital heart disease, and I didn't live long enough to receive a heart transplant. I ultimately died in the kitchen of my home. If I remember correctly, that day should have been the Star Fire Day of Abundant Harvest.)

(You: What did the Dean do for your illness?)

(Woman: He brought in the best doctors and nurses to try to cure my disease, but the results were not significant. The only treatment for my condition was a heart transplant. One month before my death, he had told me that he had found a way to treat me.)

(You: How did you and the Dean know each other?)

(Woman: We were classmates in college, just like any ordinary campus romance. He had excellent grades, and I met him during a campus knowledge competition.)

(The woman paused for a moment, looking at you curiously.)

(Woman: How did you know who I am? Why did you start by asking me these three questions?)

(You paused for a moment.)

(You: Because I already knew that you could only answer three questions.)
