"Then his motive must be that he doesn't want to live anymore." Ge Xiaolun said seriously.

After speaking, Ge Xiaolun looked at everyone with a look of self-righteousness, and he didn't see the disdainful gaze cast by everyone at all.

"Cut~" Rose was the first to break the deadlock, and in this extremely quiet situation, this soft sigh was particularly loud.

This guy ...... Are you here to make trouble? Ruiz thought to herself.

"Okay, okay, you can go out of the way first, let the professionals come." Renyi also couldn't stand it anymore, patted Ge Xiaolun's shoulder, and said.

"I'm sure everyone must be confused about what I mean by suicide, so I'll explain."

At the same time, the police seemed to be unable to wait, and some people in police uniforms continued to enter the room.

"The time is almost up, please forgive me." The officer from earlier walked up to Rhyz and bowed.

"Hmm...... Please listen to this student's reasoning at the end. Ruiz nodded and said.

Seeing that the time was ripe, Ren Yi smiled slightly and began to reason......

On the other hand.

Somewhere at the end of the universe, a black hole with a strange glow is floating between two planets, seemingly connected somewhere in the universe.

Inside the black hole, a luxurious, classical and literary academy stands.

Walking through the back garden planted with flowers and plants, a room full of books comes into view, and in the study, a man in a large robe is sitting quietly reading a book.

Suddenly, the silent study was alarmed by a knock on the door.

"What?" The man slowly closed the page and turned to look at the strangely shaped creature standing in the doorway.

"Your Excellency...... I'd like to make sure again......" the monster said resignedly.

"It's your own business, don't bother me." The man sighed and said lightly.

"Understood...... My lord. The monster bowed his head respectfully and left the study.

However, not long after he left, the study had just calmed down when a purple crack opened over the man's head.

"I don't think I'm able to concentrate on my studies today." The man sighed deeply, put the book back on the shelf, and stood up.

At the same time, in the crack, a hooded man in a purple shawl slowly fell.

"I don't know who you are, but it's rude to trespass into someone's room, isn't it?" Carl said in a flat tone, unable to tell what his mood was at the moment.

"Huh...... Didn't you look forward to my coming day and night? The purple man raised his head buried deep in his chest and said with a smile.

Beneath the mysterious hood, a pair of eyes with an eerie glint of light were staring at Carl.

"Huh? Are you ......" Carl seemed to notice something wrong.

"Void ......"

……

"Alright, young man, start your reasoning, we're in a hurry." The police officer said to Renyi with some impatience.

After all, this kind of life-threatening case was handed over to a group of college students to solve, wasting a lot of time, and it was not clear whether they had destroyed the scene, so the attitude of the police officers was very poor.

"There is no need to investigate, this person is a suicide...... Ah no, it should be said that it is a homicide without a murderer. Ren Yi said with a smile.

These words made everyone present unable to understand, and they all looked at Renyi suspiciously, waiting for the latter's explanation.

"I wonder if you've ever heard of oxygen poisoning?" Renyi didn't answer immediately, but asked instead.

"Oxygen, is it still poisonous?" Rui Mengmeng was a little puzzled and disbelieving.

"Probably not, after all, this thing is a necessity to maintain our lives, and it can't be poisoned, right?" Zhao Xin also expressed disbelief.

"Emma, I heard the word oxygen poisoning for the first time when I was a child." Liu Chuang was more direct and looked at Renyi with a sense of mockery.

This guy ...... Definitely here to make trouble.

As soon as Renyi's words came out, Ruiz and the police officer came to this conclusion at the same time.

"Hahaha! It seems that you really don't know that oxygen is actually poisonous. Renyi said with a laugh.

"Why?" Rose asked, frowning.

Although she has a higher education and is well-read, it is the first time that Rose has heard of the term oxygen poisoning, and coupled with Renyi's previous reasoning, Rose is temporarily unable to judge whether what Renyi said is true or false.

I saw the corners of Ren Yi's mouth rise slightly, and said:

"The basis is ...... Mortality rates in people who have inhaled oxygen are as high as 100 percent......"
