After hearing Chen Ge's question, the three people in the iron cage reacted differently.

The old man, his face covered in grease, licked his fingers silently, as if he was savoring what he had just eaten.

The woman's eyes widened and she struggled desperately in the iron cage, like a big fish thrown onto the shore.

The middle-aged man's behavior was the most abnormal. He was the only one among the three who kept staring at Chen Ge without blinking.

"Why are these three people imprisoned in a mental hospital?" Chen Ge first walked to the old man's iron cage. There were two plastic bowls in the iron cage made of welded steel bars.

The old man noticed someone coming, but he was not afraid. He sat in the middle of the cage, sucking the remaining oil stains on his fingers as if no one was around.

"He is the one transferred from the first ward." Chen Ge looked at the old man for a long time but could not find anything wrong with him. "His hair is uneven. Someone shaved it with a knife. This hair should be newly grown."

Seeing the old man's hair, Chen Ge thought of the hair on the back of the nurse's station counter. Some of the hair was half black and half white, so it should belong to the old man in front of him.

"The hair has grown so much after being shaved once. It seems that the old man has been imprisoned here for a long time." At that time, Chen Ge compared the length of hair and thought that there were four different people whose hair had been shaved, but there were only three people in front of him.

"There is one more that has not been found."

Chen Ge's eyes swept across the woman, and finally stopped at the middle-aged man. His hair was very long and messy, covering his head. "This man's hair doesn't seem to have been shaved?"

Chen Ge became more careful. Shaving the head seemed to be the murderer's evil hobby. He was playing with his prey, but why would the murderer let the middle-aged man go alone?

Does the middle-aged man know the murderer? Or is he the murderer?

Chen Ge was shocked by his own thoughts. At the junction of the first and second wards, Chen Ge saw a strange face. It was an asymmetrical and somewhat deformed face.

Being able to walk freely in the ward and also monitoring and following him, the man with the deformed face should be the murderer behind the scenes, but now there is another middle-aged man. From this point of view, there may be more than one murderer who imprisoned the victim.

Chen Ge clenched his hammer tightly, and even thought of a worse situation in his mind.

What if everyone in this ward, except myself, is the murderer?

Of course, this situation is unlikely.

He thought for a moment and finally stopped in front of the woman.

Neither of the two men were willing to answer his question, so he tried to remove the pillowcase from the woman's mouth to see if he could get any information from her.

"Don't be nervous, I'm here to save you." Chen Ge shook the lock on the cage. Without the key, if he just used a hammer to smash it, who knows how long it would take to get the three people out.

The woman seemed to have a natural fear of living people. As soon as Chen Ge approached her, she began to have a seizure, sobbing, shaking her head and waving her hands, and became very emotional.

"Calm down, I won't do anything to you." Chen Ge walked around to the woman and was about to take the pillowcase off her mouth when the middle-aged man who had been silent behind him suddenly spoke.

"I advise you not to let her talk. She's very noisy."

Turning his head, Chen Ge saw a pair of gloomy and wary eyes. It was unclear whether this middle-aged man was like this to everyone or just to Chen Ge. He showed a kind of disgust from the bottom of his heart, as if what Chen Ge was doing made him extremely disgusted.

"She's noisy?" Chen Ge was not afraid of them talking, but he was afraid that they would refuse to communicate.

As long as these people speak, he has the opportunity to obtain useful information from their words.

"Yes, it's very noisy." The middle-aged man spoke in a rigid manner, and he seemed to feel disgusted even talking to people.

"Can you tell me the reason? Is she mentally stimulated?"

Chen Ge asked two questions in a row, but the middle-aged man remained silent. It was not until Chen Ge reached into the cage again and tried to take the pillowcase out of the woman's mouth that the middle-aged man uttered three words: "I don't know."

"What do you know? You don't know this woman, but do you know the old man in the first cage?" Chen Ge asked a question that he had always been curious about: "Why are there only two plastic bowls in his cage, and only one in your cage?"

"I can tell you, I just hope you don't let that woman talk, she's very noisy."

The middle-aged man repeatedly emphasized that women are noisy. Chen Ge was curious, but he agreed on the surface: "Okay, but only if you don't lie to me."

"I never lie." The man sat in the iron cage, his voice low: "The old man was in poor health and had a bad temper. After his wife passed away, he stayed at home alone, relying on his son for support. His son is a doctor, his salary is not high, but it is no problem to support the two of them. But later, I don't know what the old man was thinking, with the help of others, he married a widow. His son didn't object, but just moved out and sent him money every month."

"Things never go by. Not long after, his son, a doctor, went crazy because he was said to be in frequent contact with patients. He also injured several patients in the hospital."

"His son lost his job, and the patient's family refused to give in and paid all their assets before the matter was settled."

"My son went insane and needed treatment. The public mental hospital costs three to four thousand a month, which is too much for him to bear. At the critical moment, the hospital where his son used to work stepped forward and admitted his son to the hospital at a fee far lower than that of the public hospital."

"I was once a doctor but now I am a patient. My son's personality became more and more strange, and he was not cured until the hospital closed down."

"During the time his son was in the hospital, the old man's health was getting worse and worse. He was too old to be hired for work, so he gave all his earnings to the hospital. The new widow also divorced him."

"He told his son about his predicament, hoping that he could cheer up and overcome the disease."

"Unfortunately, not long after, his son bit someone from the same village."

"When his son had an attack, his desire to destroy became extremely strong. In the end, the old man had no choice but to make an iron cage and lock his son in it."

"It didn't take long for the old man to fall ill. Not to mention treatment, even eating has become a problem."

"The old man looked at his son who was suffering from seizures from time to time in the iron cage, and finally made a decision."

"He would wait until his son had an attack before bringing him water. He would put two bowls outside the cage, one containing clean water and the other containing rat poison."

"He let his son choose whether to live or die."

The middle-aged man had a cold face. He seemed not to have spoken so many words for a long time, and his face was paler than before: "This is why there are two bowls of water at the door of the old man's iron cage."

After listening to the middle-aged man's story, Chen Ge remembered the words under the counter of the nurse station: I will pay you back for everything you have done to me.
