For this office, Luo Sheng has been to it countless times. Located at the end of the corridor on the third floor of the institute, it is filled with mountains of documents, almost all of which are research materials. "Messy" and "all white" are the first sights of this room as soon as the door opens.

Cheng Yin sat among these snowflakes, his skin was frighteningly white, even his hair was the color of egg white, and his facial features were very delicate, but he looked like an outlier who didn't eat people. If you want to find a word to describe the image he gives people, that is-either death and demon.

Moreover, from beginning to end, Luo Sheng never knew how old Cheng Yin was, and his age was the first article of the taboo regulations of the institute.

When he first came here, Luo Sheng didn't care about this, what does it matter how old the boss is, it doesn't affect his research and salary, and age is a private issue, Luo Sheng didn't think to ask at first. And according to visual assessment, Cheng Yin's appearance is about twenty-five or sixteen years old. As long as it conforms to conventional logic, and it is not a 3-year-old child who takes him to analyze the paradox of thought, Luo Sheng will not be too curious.

Cheng Yin only wears a white shirt all day long, and he is dusty, and he is suspected of being a celestial. As he sat in this room, buried in his papers, it was hard to see that there was anyone in the piles of papers.

Luo Sheng has always believed that Cheng Yin has albinism, or hemoglobinia syndrome, or some physiological deficiency disease. In short, every time he saw Cheng Yin, he always felt that this race was about to become extinct, and wanted to give him an isolation mask to wear, and he was very worried that this white person would die after being infected with daily bacteria.

Coming to the end of the corridor and pushing open the door, Luo Sheng saw a pale hand holding a red ballpoint pen - not an exaggeration - such a sign was indeed needed for Luo Sheng to accurately identify where Cheng Yin was sitting.

Cheng Yin never used a table, this is one of his habits. Sit on the floor in the pile of papers, find the information he needs from the pile, and then record or rewrite or copy it. Habit 2, Cheng Yin will sit in a place with his back to the sun, this room only has the east window, the purpose is to let the sunlight shining from the window in the morning all shine on his back, he likes to dry his back. Habit three, he always keeps an hourglass on the left-hand side—on top of stacks of papers.

Seeing Cheng Yin beckoning, Luo Sheng took off his shoes and walked into the room. But when he came to Cheng Yin, he found that this day was a little wrong compared to usual.

Before Luo Sheng could carefully observe what was wrong, Cheng Yin beckoned him to sit down, and his almost transparent face smiled at him, and he found something from the pile of papers next to him.

"This is my room key, you take it."

After speaking, he handed the key to Luo Sheng. Luo Sheng knew that this was the key to the second room on the left side of the third floor, the place where he stood on the door with game cards plastered inside. As long as it is not necessary, he will never want to go in, so what is he doing with this key?

Luo Sheng took the key, and a layer of strangeness appeared in his heart. He was just about to ask, "Why give it to me?" But before he asked, Cheng Yin preemptively said: "Don't ask, you will naturally understand when you use it." ”

Cheng Yin's face is better than that of a patient with blood loss, and he never sees joy and sorrow, just like a perfect mask. Whatever he's saying, you're only reading what he's saying, and if you want to be clever and read your heart further from your expression, don't do that, the more you read, the more terrifying it becomes—hollow and not human, you choose.

Although Luo Sheng doesn't know Cheng Yin well, he still understands his temperament, usually what he doesn't let ask, if you point a gun at him, you won't win.

He didn't say much, nodded and put the key in his pocket.

Usually, Cheng Yin called Luo Sheng to this room, which must be for a discussion on a specific issue, so at this time he waited for the other party to cut into the topic, but he couldn't have imagined that this time the topic was actually himself.

Then, without any foreshadowing, Cheng Yin asked: "Luo Sheng, there is a second you in this world, the three dimensions of physiology, society and psychology are no different from you, the thoughts are the same, the memory is the same, and even the things in the stomach are synchronized......

That strange conversation began at 18:10 on the afternoon of July 1.

And how did this passage, and later, evolve into a situation where Luo Sheng was hunted down and killed by "himself"? Where did the other self come from? What's the problem? This is a series of facts that cannot be explained by common sense, but it is already valid. The joke that Luo Sheng had always wanted to refute made him unable to find where the loopholes were.

The only thing he could figure out now was to compare the shadow with everything he had before he killed him.

At this point, Luo Sheng and An Yi sat in the stone chamber of Tabulun Temple, analyzing the unbelievable shooting incident just now.

Luo Sheng thought back to the shadow he had glimpsed in the darkness, the features of that shadow—some important factors that he had overlooked because of the troubles in front of him—that were revealing themselves one by one, matching them in terrible proportions with himself in the past few days. The result is 1:1.

Luo Sheng was stunned, his eyes were glazed, and he couldn't say a word.

An Yi looked at the people around him and had the precursors of mental disorder, and hurriedly patted him on the shoulder.

"Hey, are you sure you read that right? There are not one or two people in the world who look alike, and I have been a police officer for so many years, and I have also encountered situations where two suspects in different cases look like brothers. ”

Luo Sheng came back to his senses, took a deep breath, turned his head and said calmly: "An Yi, there are not too many coincidences in the world, and too many coincidences are inevitable." If you think about it, from the time you saw me shooting on the roof, don't you think that everything is coincidental? ”

Seeing that An Yi began to sort his thoughts, Luo Sheng continued: "I'll analyze it for you now, the day I shot on the roof was July 9th, if I'm not mistaken, the time of my killing was about 21:40, because when I was put in a police car, I checked the time. And on July 1st, after I finished talking with Cheng Yin at 6 o'clock in the afternoon, he asked me to go to Iida District to pick up an important document, I had dinner before driving over, and when I arrived at the designated place, it was almost around 21 o'clock, and Iida District is a one-story house. ”

An Yi raised his head and said slowly, in disbelief: "So you mean, you on July 9th, killed you on July 1st?" It doesn't make sense. ”

Luo Sheng shook his head: "No, I can't understand it like this, but I killed another me on July 9 on July 1st, you may feel very confused now, you listen to me first." Luo Sheng found a small pebble, wrote Luo Sheng 1 and Luo Sheng 2 on the ground, and told An Yi to pay attention to the date, and then continued.

"On the night of July 1, I took the information and peeked at the contents, and when I wanted to go back to the research institute to find Cheng Yin to ask clearly, I found that he was missing. But the next day, that is, on July 2nd, I didn't rush to find Cheng Yin, but went to the hospital to meet Yu Weiliang, she asked me to dinner, the date was very bad, you know, I was going to drive her home, due to the quarrel, she left angrily, and I turned back to the institute. On the surface, this is just a couple quarreling and breaking up, but in this case, it is an incentive to change your choice. If I had insisted on sending Yu Wei Liang home, or if I hadn't had an argument with her at all, then everything might have been completely different by now. Death is coming, you've seen it—"

An Yi said thoughtfully: "Inducement, passive choice, change...... ...... do you want to say?"

"I want to say, this inducement made me look for Cheng Yin with all my heart, that night, I went back to the research institute, and in that room piled up with documents, I found Connolla's contact information, you think about it, on the night of July 10th, where are the two of us-"
