Reborn Nine Zero became a top student, she was doted on by her seven brothers

"Zhizhi, that's amazing. I remember so clearly and you've learned so much!" Xiao Junze was very happy. Song Zhizhi quickly booed, "Don't be so exaggerated. Others will take it seriously. I can only talk on paper, that is, remember."

, I haven’t really tried it yet, I’m so nervous!”

She only knew that she had to follow through on this matter, but she didn't know what she was doing.

"Okay, I won't say anything anymore. Then you do the experiment, and I will assist you and write down the records!" Xiao Junze chuckled and began to get seriously involved in the experiment.

Everyone was talking quietly while doing it, carefully and carefully, carefully and carefully.

Song Zhizhi first used a measuring instrument to take 0.5 g of plant material, washed it with double-distilled water, and blotted it dry with filter paper. Then he put about one centimeter pieces of the material into a pre-cooled porcelain mortar.

Then liquid nitrogen is added, quickly cooled, and then ground into fine powder, the finer the better.

Because eukaryotic cell genomes are large, care should be taken to operate gently and at low temperatures to minimize mechanical and chemical shearing of DNA, thereby obtaining relatively complete DNA.

Therefore, Song Zhizhi's movements were gentle and gentle, and her movements were a little slower.

In fact, this is a simple and convenient method for extracting total plant DNA. In the basic experimental content of university biology experiments, in addition to this, there are also PCR, agarose nucleic acid electrophoresis, gel recovery and purification of DNA, and extraction of E. coli plasmid DNA (alkali lysis method

), preparation of competent cells, screening and identification of recombinants and transfected cells, etc.

After Song Zhizhi and Xiao Junze finished a complete session, she was thinking about when she could try other ones in the laboratory. This feeling was really great!

In order for both of them to get exercise, Xiao Junze took the lead again, and Song Zhizhi assisted in writing a record. Because of Xiao Junze's special appearance, many students had been staring at them for a while.

I felt a huge crisis in my heart. Xiao Junze was not an empty shell. Even this little kid I picked up at random was so familiar. He was not at all like a soft persimmon who relied on Xiao Junze's strength to get through.

Another point is that some students who were unfamiliar with the experimental process also learned from watching them!

Many people have secretly happy faces. Even if they are not completely incompetent, it would be good to learn from past mistakes!

After the two of them finished their work, they packed up their things and cleaned the instruments, they took the report and left. At the same time, many groups also finished and followed them out.

Some even run faster, so hurry up and submit your report!

Song Zhizhi and Xiao Junze smiled at each other and continued walking slowly.

It only took one afternoon to complete the task. After handing in the report, the two went to the cafeteria to have dinner in advance, and then went for a walk in the dam to discuss what they had learned during this time.

The more Song Zhizhi listened, the more surprised she became. In every gesture, Xiao Junze was no longer the irritable young man. His vast knowledge reserves, rich learning insights, and thinking were all refreshing to her.

As for why he studied biology, he changed his mind after studying physics. There is a shortage of people in the biology field in the country, but all major junior classes focus on mathematics and physics.

So he wanted to come here, and Song Zhizhi expressed his admiration.

Xiao Junze just smiled and sent her back to the dormitory to rest. When Song Zhizhi walked in, he turned around and walked towards his building. As the sun set, his murmur was unclear, "There is another reason. I want this lonely place."

There is someone to accompany you on the road!”

It doesn't matter if Song Zhizhi accompanies him or he accompanies Song Zhizhi, that's fine!

Early the next morning.

While everyone was still having breakfast in the cafeteria, everyone's experimental scores came out. Teacher Wu posted them on the bulletin board one after another, with the elimination list written on it.

"Ah ah ah, luckily I just ate, otherwise I would have gone back hungry!"

"I'm actually there? Why, I'm the main force in our group!"

“Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu It’s over, I will definitely be beaten when I go back.

"The shortest child looked down upon him!"

…

This was what Song Zhizhi heard when she came over. She was so frightened that she thought she had been eliminated, so she quickly went to the list to see if her name was there.

This is also the first time that I don’t want to see my name on the list!

Phew, no!

Song Zhizhi read it three times and felt relieved.

Many security guards came over to help carry their luggage. Within an hour, all the students on the list were asked to leave the school. Song Zhizhi and Xiao Junze only glanced at the direction of the door, turned around and entered the big classroom.

In the next few days, seven professors from the biology department of the university came together with the teacher professors to carry out careful and rapid teaching. The content was undergraduate, and occasionally involved more profound knowledge points, which also caused everyone a headache.

In the first three days, because the intensity was too high, more than a dozen students asked to leave. After another three days, more than a dozen people left. At the end of seven days, less than one of the 150 selected students was left.

One hundred and twenty people.

So the second round of elimination exams began. Everyone was too busy to talk and spent all their free time studying more.

Song Zhizhi's plug-in played a very important role at this time. In addition to studying during the day, he would go back to simply sleep at night, get up at 11 o'clock, and go into the Shiwan Online Library to continue studying for five minutes, which is the five outside

Hour.

She spent five hours more than others every day, and her previous study progress was fast and her foundation was solid. She stayed within the top three in every subsequent exam, and even passed first once.

Of course, Xiao Junze was also there, ranking up and down with her, which amazed her. Apart from her, the other people in the top five were truly geniuses among geniuses!

When the training camp reached the third month, there were less than thirty people left in the camp, and the professors were particularly concentrated, allowing teachers and students to start talking and discussing.

Song Zhizhi made progress every time and was considered a man of the hour. At first, some people suspected that her good relationship with Xiao Junze relied on the help of others.

But later it was proven time and time again that her strength was his own, and the more I thought about it, the more terrifying it became.

In the last three rounds of exams in the last month, half of the members were eliminated, leaving only the final four.

Song Zhizhi felt that she had directly entered the sprint stage of her senior year and was extremely nervous. Xiao Junze was equally nervous, so he dragged her every day to occupy all the free time Shi Yiguo could occupy.

After understanding it, Song Zhizhi no longer decided to be superior to the other countries. He was also a little old man who could make fun of them. He only had a high IQ, good character, academic rigor and hard work.

There are still five days before the New Year, and the training camp has also ushered in the finals of eight to four.

Those who have been retained until now are actually among the elites in the country. Even if they fail to pass the exam, they will be directly admitted to well-known universities after leaving this school.

But everyone is still working hard. After all, no matter how good it is, it is better to be a teacher from the same country!
