It's hard,

Almost impossible.

After the three young postdocs saw this information, they immediately retreated. After all, Xu Mang's proposal to solve the problem of replacing a certain DNA fragment with a target sequence was a false proposition in the world. It did exist, but it could not be solved.

be realized.

"Do you find it difficult?" Seeing the expressions of the three of them, Xu Mang knew that they might think they were crazy for making such requests, but these requests were made by others, and then he said helplessly: "This is science."

It’s a request issued by the hospital, so... let’s do our best.”

Suddenly,

The three of them didn't say anything, and silently accepted the unsolvable difficulty in front of them. If the person standing in front of them was not Xu Mang, they might have left, but it was Xu Mang standing in front of them, and they felt that there might be a chance.

.

"Professor Xu?"

"What approach should we take?" asked a postdoc: "Should we use the AI ​​model as before? Use artificial intelligence to give new life to gene editing research?"

Xu Mang shook his head and said calmly: "I don't know... maybe, but we first need to complete the theoretical framework of replacing a certain DNA fragment with a target sequence, and this problem is not the only problem we need to solve.

New problems may arise at any time.”

Anything new?

this...

The problem of replacing segments with target sequences is already outrageously difficult, but I was told that this was just one of many problems.

Finally started working,

However, I never expected that the so-called starting work means repeated experiments from the crispr-cas9 system, and only recording the process of each failure. Xu Mang is responsible for checking the process of these errors.

no way,

This is the best way Xu Mang can think of. By comparing the error process, he can find the starting point. One or two days are relatively stable, but as time goes by, everyone's enthusiasm is gradually worn away.

Like a zombie.

this day,

There are still less than five days until the school holiday.

Postdoctoral fellow Xiao Chen came to the laboratory. He was going to ask for leave from Xu Mang in advance today. The Spring Festival was coming soon and he had to go home early to avoid the peak period of Spring Festival. However, when he told his other two colleagues about his idea,

Only then did I realize...the three of them actually had the same idea.

"???"

"???"

"???"

Xiao Chen said with a confused look on his face: "The three of us...all have to go back? What should we do with this...this project? Let Professor Xu Mang stay alone in the laboratory? Although he is half a native of Magic City,

But is it too cruel to him?"

"Then what should we do?" Xiao Shen said with a bitter smile: "You have to go home, right?"

"yes."

"After all, it's the Spring Festival, so I should go back. I haven't been back for a year." Postdoctoral fellow Xiao Qian said: "Actually, this problem... won't be solved for a while. We've been working on it for a week and we're still stuck in the same place. Why not relax a bit?"

Change your mood."

At this time,

Xu Mang slowly came to the laboratory carrying a bag of fried buns and two bags of soy milk. When he saw the three of them sitting together and chatting, he asked with a smile: "Have you had breakfast? I bought a lot of fried buns.

How about eating some together?"

Seeing Xu Mang's arrival,

The three of them didn't know what to say for a while. Finally, Xiao Chen said: "Professor Xu... I plan to ask you for leave today. I want to go home early to avoid the Spring Festival travel rush. I haven't been back for a year..."

"Professor Xu, I also want to ask for leave."

"Me too."

Facing the three people's request for leave, Xu Mang was not surprised. He nodded with a smile: "All approved, of course I have to go back for the New Year, by the way..."

The words fell,

Xu Mang took out three red envelopes from his satchel, handed them to the three of them respectively, and said seriously: "I originally planned to give it to you later, but since you are going home today, let's give it to you now.

.”

The three of them were surprised when they suddenly received a red envelope from Xu Mang, but they were even more surprised when they saw that the red envelope was a bit exaggeratedly thick, actually worth 10,000 yuan.

"this..."

"Professor Xu?"

"The thickness of this red envelope is a bit exaggerated!" Xiao Chen said with a serious face: "We can't accept it."

"Take it."

"I don't know how much money is in it. My wife helped me prepare this." Xu Mang said calmly: "Just take it, take it, it's okay... Whoever dares to talk nonsense, let him come to me directly, and

I confronted him face to face."

Looking at the three people leaving,

Xu Mang returned to the empty laboratory again. Perhaps this was his fate, the fate of working alone. He sat in the office, smoking silently, thinking about the future, and how to face failure or success.

I have been studying the problem of replacing a certain DNA fragment with a target sequence for more than a week. I have been wandering around in a maze and can't find any way out. The process of seeking the truth has been so bumpy, and the result is even more cruel in reality.

After thinking for a while,

Xu Mang decided to go for a walk outside. Staying in the office for a long time would cause his nerves to collapse.

on campus,

Xu Mang walked all the way to the school gate and saw many students who were ready to go home. However, the scene in front of him made Xu Mang a little melancholy. He came to a coffee shop that was not closed yet, ordered a cup of coffee for himself, and sat in a window seat.

From the position, I looked at all kinds of people on the roadside.

perhaps,

On the day of birth, no one knew that this was actually an unreasonable world.

Some people's dream is the stars and the sea, some people's dream is a house, some people are born with talents, some people rely on sweat to survive...We can't lose at the starting line, but some people always stand at the finish line.

.

This is reality, this is the reality where there is a huge gap, and finally accept that you are just an ordinary person.

Accepting your fate?

However...

What Xu Mang saw was hard work. Living in this unreasonable world itself requires a lot of courage.

"Hello?"

"Wife?"

"I'm at... the coffee shop." Xu Mang received a call from Xiao Man and said with a smile: "No... everyone has gone home for the New Year, and I am the only lonely old man left in the laboratory, so what can I do?

What should I do? I can only sit outside and drink coffee."

"..."

"Speaking of going home." Yang Xiaoman suddenly fell into deep thought and said seriously: "Husband...will I go back to your house on New Year's Eve this year, and then go back to the Magic City on the third day of the Lunar New Year?"

"Um!"

At this time,

Yang Xiaoman asked squeakingly: "What gift are you buying?"

"unnecessary."

"It's enough for my parents to see you coming. No gifts are needed." Xu Mang said calmly: "How about... buy some jewelry and get some tea for my dad."

"Um!"

"I'll do it right away."

snap,

Hang up directly,

Xu Mang just finished a cup of coffee, silently returned to the laboratory, and started his clueless day. It was not until noon that Xu Mang woke up from this hazy state, had a not-so-delicious lunch, and continued to start.

I was restless in the afternoon.

Boil and endure,

The whole day was passed by Xu Mang. There was really nothing he could do. He originally wanted to rely on the system to solve the problem, but found that this time the system had given him restrictions and he could only solve it on his own. What was even more egregious was that he was not careful.

A task was triggered and required to be solved before the Chinese New Year.
To be continued...
