- Something about AI experiments? How is that possible? I don't even remember seeing anything like this.

Xian Yu replied with some disapproval.

[But what are you trying to do in a mental hospital this time?] ……〕

- Let's see if we can find any clues about the person who killed me.

Xian Yu said very casually, but he never knew the bottom in his heart - it was so late when he found out that he was really murdered, and he didn't know if the person who murdered him had erased all the evidence......

"It's a pity that too much time has passed, and it's a pity that those people didn't go to the fourth floor to see the reason for the broken railing...... If the railing is used as evidence now, it is estimated that no one will believe it......" Unconsciously walked to the door of the mental hospital, Xian Yu looked at the white building inside, and couldn't help but sigh quietly.

"Alas, my brain hurts...... Xian Yu said, rubbing his head with his hand.

Suddenly, a figure burst out from behind the grass in the mental hospital, and almost instantly came to Xian Yu, grabbed Xian Yu's hand, and dragged Xian Yu over.

Xian Yu looked confused, and when he reacted, he was already behind the same bush as a young man, looking at each other.

"Who are you? How did it get here? Why did you pull me over? Xian Yu raised his eyebrows and asked, "Also, how do you know that the psychiatric hospital has a blind spot for surveillance?" ”

"Huh~ My purpose is the same as yours." The young man, perhaps running too fast just now, gasped and said, "I came with those people in the morning, they only watched downstairs, and they didn't let people go up to the fourth floor, I took an opportunity to sneak up to the fourth floor and found traces of artificial partitions on the railing, while the gang below were reporting fake news, so I want to come and find clues to verify now." ”

“…… Wait a minute! …… You said those people wouldn't let you go up to the fourth floor? Xian Yu looked at the young man with wide eyes.

"That's right, claiming that the deceased is a relative of someone from a large company, don't let us go up and look around." The young man said, turning his head to look at the inpatient building where Xian Yu once lived.

"Musou Company? So how did you manage to sneak up to the fourth floor? Xian Yu's eyes were full of suspicion as he looked at the young man.

"I bribed another onlooker to help me make trouble and attract attention, and then climbed through the window to the first floor, and then slipped to the fourth floor." The young man grinned.

“…… Kudos to your wit. The corners of Xian Yu's eyes twitched.

"So how did you know about the railing?" The young man suddenly withdrew his previous hippie smile and asked with a serious look on his face.

"Oh, I watched him fall." Xian Yu said nonsense, "He is my distant cousin, I happened to visit him last night, and I saw him fall down in front of the corridor window, and then when I went to his room, I found a problem with the railing." ”

"I see...... "The young man thought thoughtfully.

"By the way, can you take two steps to the right? - If you go to the right, you won't be able to reach the monitoring area. Xian Yu suddenly pointed to the young man's feet and asked.

"What's wrong?" The young man looked confused, not knowing why Xian Yu asked him to change his position, "Is there any difference between standing here and standing there?" ”

"Why is it no difference? ......" Xian Yu helplessly held his forehead, "You didn't notice - you ...... under your feet"

"Is there a thing?"
