Yu Fan and Chen Jiaoyang put on gloves and rummaged through the room carefully, cautiously to see if they could find some clues.

Chen Jiaoyang searched and teased: "Old Yu, Dean Wu said that people don't play chemistry now?" ”

Yu Fan picked up a pile of documents on the table, looked at them, and put them back in order, and replied: "Yes, there are indeed fewer people who study chemistry, or in other words, there are fewer people who study many traditional sciences." ”

Chen Jiaoyang: "Then you say, what are these college students studying now?" ”

Yu Fan smiled bitterly a few times: "Finance? Real estate? Internet+? Artificial intelligence? Which one makes money and which one learns, but this is also an eternal truth, people's essence is profit-seeking. ”

Chen Jieyang: "Then why did you study chemistry in the first place?" ”

Yu Fan: "I studied chemistry because of many factors, at first, I didn't like chemistry very much, and I forced myself to study chemistry because of some irresistible reasons. On the other hand, I preferred psychology at first, and I thought it was more esoteric. ”

Chen Jieyang stopped what he was doing and turned his head to look at Yu Fan: "What about now?" After saying that, he continued to flip through things.

Yu Fan: "I like it all now." Chemistry reveals the essential laws of matter, while psychology interprets the essential laws of spirit. Together, the two form the basic logic of this world. ”

Chen Jiaoyang smiled: "I, it's not as deep as you think, my father turned out to be a policeman, so I also became a policeman, it's as simple as that." ”

Yu Fan also smiled: "I also want to be simple, but isn't this being pulled into the muddy water by you?" ”

Chen Jiaoyang made a grimace, and then threw a booklet at Yu Fan: "Since they have all been pulled down, don't you have to continue whatever happens." Old Yu, look at this. ”

Yu Fan took the booklet and opened it, this should be a diary of Chen Tizhou, or to be precise, a book of aphorisms. Each page has only time, weather, and then there is an aphorism.

Chen Jiaoyang: "This Professor Chen is quite persevering, and he writes a motto every day, no more, no less. ”

Yu Fan carefully looked at these aphorisms page by page, the first page was 6 years ago, the last page was 4 years ago, and it was recorded for more than two years, and it was never recorded again.

The aphorism on the last page reads: "How much strong acid is pursued, silica is unmoved, because he only wants to fly away with hydrofluoric acid." ”

Yu Fan raised his head and looked around the room. Chen Xiangyang said to himself next to him: "It's a pity that after so many years, I don't know where he has run now, wait a while to get his file, maybe I can find any clues." ”

Yu Fan took a deep breath and said lightly: "No, he is here." ”

Chen Xiangyang was surprised: "Old Yu, what did you say?" ”

Yu Fan slowly closed his eyes, his mind continued to flash various pictures like a marquee, all kinds of clues converged to Yu Fan, like a chemical reaction naturally synthesized, Yu Fan didn't care about the process of this chemical reaction, he waited for the result of this reaction in his imaginary beaker, in this enchantment composed of imagination, Yu Fan seemed to become the master of the law of all things, he mastered the law, and at the same time looked forward to the result, slowly, the truth naturally emerged, and Yu Fan only needed to go to it to unveil its mystery.

This is the world of Yu Fan's "flow mode".

Seeing this, Chen Jieyang knew that Yu Fan had entered a state of flow, so he shut down and didn't bother him.

Suddenly, Yu Fan opened his eyes and said very quickly: "Chen Tizhou, male, 55 years old, carries a notebook with him, has short nails, has a tendency to be neurotic, and has a strong personality. Be creative, left-handed, and have a strong sense of self. The watch will be carried, but the watch is stationary. Have a history of smoking. Obsessive-compulsive tendency towards certain things, will go to the city's or even the province's largest library, archives, and databases alone. . . “

Chen Jieyang quickly tore off a piece of paper and wrote hard, recording Yu Fan's description, which was Yu Fan's psychological profile of this Chen Tizhou.

After Yu Fan finished speaking, Chen Jieyang asked curiously: "How did you deduce this information?" ”

Yu Fan picked up Chen Tizhou's booklet and shook it, and said: "A person with strong handwriting structure is generally a person who is rigorous in his work, and has a strong memory, but he later suffered from a terminal illness and had to undergo chemotherapy, and chemotherapy drugs will definitely affect his memory, so he has to bring a notebook to record things that once only needed the brain to remember." “

Saying that, Yu Fan began to pace around the room, and slowly walked to the table, his eyes were in a daze, and he fell into a kind of imagination, he imagined himself as Chen Tizhou: "If I were him." I feel like my body is getting worse day by day, and even if I have a notebook, I still have to forget a lot, and I forget which page of the notebook important things are written down, and taking a notebook can't solve my problems at the root. So I'm anxious. ”

While speaking, Yu Fan stroked the faint nail marks on the desk, and said: "I want to quickly find a way to solve these troubles, I am thinking while picking the table with my nails, this is my habit of relieving pressure." So my nails won't be too long either. ”

Then Yu Fan sat on the stool, which was a hard stool: "I like to sit on a hard stool all year round, because I am a person with a strong personality, I have to find a solution, I just thought while lighting a cigarette, I fell into contemplation, so that the cigarette butt fell on the table, I didn't even notice it, I am a left-hander again, so there are always traces of cigarette butts burning on the left side of my desk." ”

Yu Fan then stroked the ornaments on the table and said, "I have a strong sense of self, because I am used to putting a lot of ornaments on the table, and I play with them when I am bored. ”

Yu Fan touched a small clock on the table with his hand again, this small clock is no longer gone, but it is very strange that its hour, minute, and second hands actually point to the position of six o'clock together, and it is impossible for this kind of picture to appear under the condition of normal stop watch.

Yu Fan had a strange sense of anxiety on his face: "I know that my own time is short, and I am beginning to be afraid of the passage of time, so I want to let time, stop, even if I forcibly make it stop, because I have a certain obsessive-compulsive disorder, I only allow time to stand still in front of me!" What the? You guys didn't know I had OCD? Then you should take a good look at my research cabinet, all the chemicals I study are arranged by molecular mass from small to large, and I don't allow 'chaos' to happen in front of me. ”

Yu Fan has completely entered Chen Tizhou's world, and in Chen Jieyang's opinion, there are even some people who have gone crazy.

Yu Fan began to pace anxiously in the room: "No, I'm not reconciled, I want to live, the hospital can't save me, there is always a place that can save me!" No way! I'm going to get out of here, I'm going to live, I'm going to save myself, it's too late, I'm going to leave now~~~~~"

"Mr. Yu Fan?" A question interrupted Yu Fan's meditation, and it was the assistant dean who made the sound, she stood at the door with some document bags, looking at Yu Fan curiously. Yu Fan was pulled back to reality from the imaginary world, Yu Fan's forehead was full of sweat, panting, Yu Fan deeply felt the sense of oppression and suffocation in Chen Tizhou's situation at that time.

The assistant said: "Mr. Chen, Mr. Yu, this is all the files of Professor Chen Tizhou, they are all here, and, Mr. Yu Fan, you don't look very good, what's wrong?" ”

Yu Fan: "It's nothing, it's just remembering some of the past for someone." ”
