from my heart [last days]

After Shen Wen left, Xie Congxin sat there for 5 minutes.

5 minutes, 30 seconds, he used this short time to sort out the current situation and what else he could do in the remaining [-] minutes of his life.

Then he got up, and walked towards the teaching building according to the rough map Shen Wen drew just now and his impression.

Su Shiqing always said that the most important character of those who do scientific research is curiosity.

When encountering something beyond the scope of one's own cognition, one should find a way to understand it. Xie Congxin has been talked about by him for 20 years, and his thirst for knowledge has been carved into his blood. He has no other regrets before he dies. There is only one thing to verify .

Area B of Chongcheng University is backed by the mountain, and the gate is in the opposite direction. He walked along the school wall, crossed the lawn on the side of the mountain, and circled a big circle. Fortunately, he did not meet any living people or people. dead.

The sound of the playground gradually disappeared behind the ears. The teaching area was full of high-rise buildings. After the earthquake caused by the meteorite fall, the students had already evacuated. Xie Congxin found the teaching building affiliated with the School of Biology where he had classes yesterday afternoon, and entered through the small side entrance of the bicycle parking lot.

The elevator had stopped working. He walked up to the fourth floor and found a biology laboratory.

The laboratories in the university are only equipped with the basic equipment needed for biological experiments. Xie Congxin glanced at them and saw that they were barely enough.

There was a desktop computer on the desk, in standby mode, Xie Cong moved his mouse, and the screen lit up, which was a blood analysis calculation. It should be that some students were doing experiments when the earthquake happened, and they ran out before turning off the computer.

He opened the cabinet, took out a white coat that looked fairly clean and put it on. After washing his hands with alcohol by the sink, he put on rubber gloves.

There is cell culture medium in the shelf, and he uses tweezers to take out the minced meat in the lunch bag packaging bag, and puts it into a petri dish for cell culture.

Then he rolled up his sleeves, used alcohol to superficially clean the wound on his arm, and dug out a scalpel from a drawer.

The whole process was slow, as if I forgot that I might have less than 30 minutes left.

He used a scalpel to cut away bits of dead flesh near the wound.

The stinging pain in the process made him squint his eyes, but the movement of the knife did not stop, and it was done in one go.

Then this bit of dead meat was also put into a Petri dish.

— He seldom made mistakes, but he did.

Perhaps there is also a slight possibility that he was not infected.

Outside the window is the direction of the road outside the gate of the university. It is located in the suburbs, and the traffic flow is usually very small, and even after the earthquake, there is no shadow.

The sound insulation effect of the teaching building is good, and the sound from the direction of the playground can hardly be heard, and the school has fallen into a strange and strange silence.

It should be said that fortunately it is a long vacation, so there are not many people in the school?

Xie Congxin stood in front of the shattered glass window on the fourth floor, stepping on the debris, facing the warm wind in early autumn, quietly waiting for the result.

The scalpel was in the breast pocket of the white coat.

If there is time, it is better to free yourself, he thought with his hands in his pockets.

Turning into a "zombie" is really not in line with his dignity as a biologist.

At 7:35 in the morning, Xie Congxin took out the petri dish and turned on the microscope.

[Shuttle-shaped, the longest transverse diameter is about 100 nanometers, the shortest diameter of the longitudinal axis is about 60 nanometers, the nucleocapsid is helically symmetrical, the surface has a lipid envelope, and the capsid presents a high density...]

He controlled the electronic display with one hand, and quickly recorded the preliminary observation results on a blank A4 paper with one hand.

After 10 minutes, he wrote about [-] words and confirmed that there was no missing information. Then he took Xu Kaifeng's cell sample and replaced it with his own.

In less than 10 seconds, he turned off the microscope.

Write a suicide note to Su Shiqing?

He got a glass of water in front of the water dispenser, sat in front of the computer that was still working, and took out a plate of chocolates with missing corners from his pocket - it was given to him by Shen Wen after class yesterday, and he hadn't finished eating.

write something

Regrets about unfinished academic work?Speculation about a new virus?Thanks to Su Shiqing for his years of teaching?Regret not seeing Su Yuzhi come of age?Regret not agreeing to Yan Shenjiang earlier to have a relationship?

He leaned on the swivel chair, looked up at the ceiling, and thought for a while with an overly sweet chocolate in his mouth.

Academically, it is quite a pity. The HIV mother-infant isolation antidrug research in cooperation with Yan Shen has made some progress, and it is not a big problem to win a Nobel Prize next year;

There is no big conjecture about the new virus, and the observation of the electronic display is not enough. Su Shiqing is in the National Academy of Sciences. If the virus breaks out in the capital, there are so many people and so many devices in the National Academy of Sciences, there will naturally be a more comprehensive guess. don't worry about him;

As for Su Shiqing, I can thank you. After all, I have no parents and have been living in the Su family for more than ten years;

Forget it Su Yuzhi, probably wishing that he would die soon, and after he dies, no one will press his head to force him to recite the book, maybe he can let himself go as he wishes, and change his career to study art;

Forget about Yan Shen, we've known each other for six or seven years, if I could fall in love with him, I would have liked it long ago, why wait until my death to regret it?

In summary, there are not many words to write in the suicide note...

No, there is one more thing.

He is dead, who will go to Xie Lin?

Or is it praying that Xie Lin will die from the virus infection like him?

It is also impossible, the scourge has always remained for thousands of years.

Suddenly, a flash of light flashed in his mind, and Xie Congxin got up from his chair abruptly.

He squinted, walked back to the microscope, quickly installed the camera, took a picture of the image under the lens, and poured it into the computer.

The photo was enlarged, and he was leaning on the table with his arms, observing the shape of each part of the virus very carefully, and the blue light of the computer brightened his light-colored pupils.

Electron microscopes cannot illuminate RNA-coding genes, only the most basic external observations.

Shuttle-shaped, the longest transverse diameter is about 100 nanometers, the shortest diameter of the longitudinal axis is about 60 nanometers, the nucleocapsid is helically symmetrical, with a lipid envelope on the surface, and the capsid presents a high density...

He replaced it with his own sample.

After 5 minutes, he got up, the surprise in his eyes gradually turned into a sarcastic smile.

"Xie Lin... This is really, what a coincidence."
