"Professor Liu, this is our DNA sample!"

Xiao Yu handed the test tube in his hand to Liu Wei, and the test tube was a purified DNA solution.

Liu Wei took the test tube in Xiao Yu's hand, glanced at Xiao Yu, couldn't help but be stunned, a trace of surprise flashed in his eyes, this was the first time he had close contact with Xiao Yu, before he always felt that this student named Zhang Xiaoyu was a little familiar, but he couldn't remember where he had seen it, now that he was so close, this feeling was even more obvious, and he couldn't help but stare at Xiao Yu non-stop.

"Professor Liu, what's wrong with you?" Zhu Jiajia asked curiously next to him.

"Oh, it's nothing, maybe I'm a little tired from the experiment just now, and my brain is a little distracted."

Liu Wei woke up suddenly, and as he spoke, he poured some DNA solution from the test tube in his hand into a new test tube, diluted it with TE solution, and measured it with an ultraviolet spectrophotometer.

He is very serious about his work, even if it is just a test to score students, and it is not a big project at the national level, he is meticulous and careful to measure.

"The DNA is of high purity and the sample processing is complete, which is good! I'll give you guys a 90 for this set! ”

Liu Wei looked at the data on the ultraviolet spectrophotometer and looked at Xiaoyu and Zhu Jiajia with great appreciation.

"Thank you, Professor!"

Xiao Yu and Zhu Jiajia were almost jumping for joy, and this score had surpassed Zhao Lin's group and become the best score so far.

The classmates all looked at the two of them with envious eyes, and it seemed that their composition as Liu Wei's assistants was already a sure thing.

Sure enough, the results of the last two groups were mediocre, and neither of them achieved enough points to surpass Xiao Yu and their group.

"Students, the best results in this experiment are Zhang Xiaoyu and Zhu Jiajia's group, according to what I said before, the two of them will become new members of my [biosensor] project at Zhongtian University, this is a good learning opportunity, in the future, I will continue to recruit assistants among the students, please study hard and cherish every opportunity to experiment!"

Liu Wei's last speech stimulated the enthusiasm of all the students, and the students who were originally full of regret were overjoyed, and it turned out that there would be a chance in the future, and almost everyone was gearing up to perform well in the next experiment.

After class, Liu Wei specially kept Xiaoyu and Zhu Jiajia, gave them a brief introduction to the new project, and told the two that in this project in the future, they would become Wu Fei's assistants.

Xiaoyu and Zhu Jiajia realized at this moment that it turned out that the two of them entered the project team not because Liu Wei was eager for talent, but because of the school's special regulations, first-year students must participate in the new project.

The school has considered it very comprehensively, and wants to let talented students who have just stepped into the university get in touch with some high-level technical research as soon as possible, broaden their thinking, and plant beneficial seeds for their future learning and development.

Otherwise, with Liu Wei's great fame, it would not be easy to find an assistant? As for finding these two rookies who have just entered college?

Of course, in the project team, their work is naturally the most basic, although they do not sweep the floor and wipe the floor, but the hard work of serving tea and water, cleaning up and sorting out experimental equipment is naturally inevitable.

The two of them have no opinion on becoming Wu Fei's assistant, Wu Fei's ability to stay in school as a teacher is enough to prove her strength, she was able to be selected by Liu Wei into the project team, not to mention luck, it was completely by virtue of her excellent academic attainments, and she stood out from dozens of candidates.

Xiao Yu and the two also have another plan, they will prepare the two kinds of poison in the future, it must be indispensable to borrow the advanced equipment of the laboratory, the equipment of the laboratory of the Department of Bioengineering of Zhongtian University is already the top in the country, and the equipment in the laboratory of the new project team must be much more advanced than the equipment used for teaching, after becoming a member of the project team, you can freely enter and exit the laboratory of the project team, and use the equipment of the laboratory freely while outsiders are not there.

Today is the day of the Esports Association event.

In the afternoon, after Xiaoyu finished class, she went to the activity room of the E-sports Association for a turn, and saw that Han Bingzheng was concentrating on following the extreme training method she gave her, guiding Guan Yushan and Wen Jingguo to do targeted training, while Yang Junjie was playing a practice match with Zhu Jiajia to help her recover.

After sitting for ten minutes, these people were busy with their own work, but no one took care of him, Xiao Yu realized that he was now an idler, and Han Bing had obviously excluded him from the competition list.

After watching them train for a while, they felt that they had nothing to do and were a little bored, so Xiao Yu and Han Bing said hello and walked out.

Standing at the door of the activity room and thinking about it, since the cooking competition, I haven't been to Qixian Ju for a week, and I just have time today, so I just go there to have a look, and by the way, tell Shi Jianguo about the next round of cooking competition.

The Qixian Bureau is only a few minutes away from here, and Xiaoyu doesn't want to drive, so he walks there.

Today's weather is very good, the autumn sun is warm on the body, and even the bottom of my heart is comfortable. Along the way, Xiaoyu stopped and stopped, and by the way, he walked around the characteristic shops next to the road, which was very relaxed and freehand, and his heart was quiet and peaceful, and he secretly thought to himself, it seemed that he had not had such a leisurely day for a long time.

A bus stopped at the station not far in front, and more than a dozen passengers came down one after another from above, Xiaoyu found that among the passengers, a middle-aged man dressed in a suit and leather shoes, the back was very familiar, and after a closer look, he immediately recognized it.

I was overjoyed, and I just wanted to step forward, but I saw a person wearing an old camouflage military uniform suddenly rushing up, snatching the briefcase on the middle-aged man's shoulder, and running in the direction of Xiaoyu as if flying.

"Robbery! Someone! Someone is robbing! The middle-aged man immediately shouted loudly.

Several passengers who got off the bus first heard the shouts of the middle-aged man, turned around and found someone robbing and stopped in front of the bag thief.

The bag thief was like a mad tiger, extremely brave, and he was intercepted by three or four passengers in a row, and got out of trouble, and one passenger was hit by him with his shoulder, staggered four or five steps, and sat on the ground.

"Don't stop him, he has a fellow party nearby, these Xinjiang people have knives on their bodies, they can be ruthless, let's call the police quickly!" An old man shouted from the side, apparently knowing something about the origin of the bag thief.

Xiao Yu took a closer look, and sure enough, this bag snatcher had a high nose and deep eyes, and he looked like a Xinjiang person, seeing him flying towards his side, Xiao Yu naturally would not be afraid of him, stepped forward and stopped in front of him.

"Young man, hurry up and get out of the way, don't suffer the loss in front of you!" There was a kind reminder from the old man behind him.

Xiao Yu smiled slightly and did not back down.

"Get out of here!" The bag thief heard someone shouting to call the police, obviously a little anxious, his expression was very panicked, and when he saw Xiao Yu blocking in front of him, he hated the root of his teeth even more, so he repeated the trick and hit Xiao Yu with his shoulder again.

A hint of ridicule flashed in Xiao Yu's eyes, and he didn't see him make a gesture, so he flew up and kicked on the lower abdomen of the bag thief, this kick was like lightning, and the bag thief didn't have time to react, so he was kicked to the ground by Xiao Yu, and screamed like killing a pig in his lower abdomen.

Xiao Yu shook his head, an opponent of this level was too weak, and he couldn't even use half of his strength, so he couldn't stand it.

Leaning down, just as he wanted to pick up the briefcase that had fallen under his feet, he heard a burst of exclamations from the crowd of onlookers not far away, and at the same time, out of the corner of his eye, he found a figure on the left and right rushing towards him, and these two people were holding bright short knives in their hands.

Both of these short knives were more than a foot long, and the newly opened edges, shining with cold light, looked extremely sharp.

Sure enough, as the old man said, this bag snatcher and his accomplices responded, and when they saw that someone dared to stop them, these two people moved their knives without thinking about it, obviously lawless and arrogant.

Xiao Yu's eyes flashed coldly, and a 'phantom step' flashed past the two of them, stretched out his left and right hands, and accurately grabbed the wrists of the two people holding the knife, and slammed it hard.

Listening to the crisp sound of the bones of 'click' and 'click', the two accomplices of the bag snatcher screamed miserably, the short knife in his hand fell to the ground, and he rolled on the ground holding his wrist, and the wrists of the two had been broken by Xiao Yu in one move.

"Good kung fu! Hey, this guy must be from the martial arts team! Kung Fu is awesome! ”

"Yes, not only is the kung fu great, but the person is tall and handsome, so he can go to the movie!"

"Hehe, these Xinjiang people are unlucky, they deserve it! They are too rampant, they dare to commit murder and hurt people in broad daylight, and now they can kick the iron plate! ”

The crowd, who originally had a heart hanging for Xiao Yu, saw that Xiao Yu had subdued the gangsters, so they put down their hearts and discussed happily.

Xiao Yu picked up the briefcase on the ground, ignored the gangster who was still lying on the ground and wailing, took a few steps forward, handed the briefcase to the middle-aged man in a suit and leather shoes, and said, "Comrade Zhou, look at it, is there anything missing?" ”

The middle-aged man took the briefcase with a grateful face, and when he heard Xiao Yu call him 'Comrade Zhou', he was stunned at first, looked at Xiao Yu carefully, as if he remembered something, with a sudden realization on his face, and said, "It turned out to be you!" Zhang Xiaoyu! ”

Xiao Yu smiled and said, "It's me, I didn't expect your memory to be so good!" We've met once, and you remember my name. ”

"Hehe, Xiaoyu, I don't have a good memory for doing this job! Thanks to you today, the money doesn't matter, if the documents in this bag are lost, I really want to jump the Huangpu River! ”

The middle-aged man unzipped the briefcase and carefully checked the contents before a relieved expression appeared on his face.

This person is the mysterious person Zhou Zhi who helped Xiao Yu a lot in the Secretary Yan incident last time, and the two have not met again since they came to Xiao Yu's store that day to learn about the situation.

Until now, Xiao Yu didn't know what he did, and he once asked the middleman Zhou Zhihao once, but the kid was very tight-mouthed and refused to say anything.

Seeing him again at the bus stop today surprised Xiao Yu, in his mind, this Zhou Zhi should be a big man, and the level must not be low, otherwise it would be impossible to divide Secretary Yan by two.

With Zhou Zhi's identity, how can he take the bus like ordinary people?
