On Tuesday, the first period in the morning was Yu Yang's class.

During the recess, Xu Qingrang ran to the position behind Mu Xueran and gently poked her back shoulder, "Xueran, Xueran." ”

Mu Xueran turned around and looked at him suspiciously.

Xu Qingrang lowered his head slightly and asked in a low voice, "Who was the girl who was with you in the waiting area outside the Century City Cinema that day?"

"Huh?" Mu Xueran frowned slightly, and said in her heart: Ah Xun He knows, then there is only Nuan Nuan.

"What's wrong?"

Xu Qingrang coughed lightly, and said a little hesitantly: "Just ask." ”

Mu Xueran raised her eyebrows, looked at him fixedly, as if she wanted to see the answer in his eyes, and after two seconds, she said, "My best friend." ”

"Does he have a boyfriend?"

Hearing this, Mu Xueran chuckled, probably guessed his purpose, and said in her heart: What's the matter lately? First Duan Hanyu asked her about Ren Mengxin, and now Xu Qingrang came over to inquire about Lu Zhinuan, could it be that the people around her have been red recently?

"You can't have fallen in love with her at first sight, do you? Mu Xueran teased.

Xu Qingrang didn't squirm, just smiled a little embarrassedly, and said, "So, for the sake of our love affair together, you can tell me." ”

"Nope. ”

"Huh?" Xu Qingrang was slightly stunned, and the next second he realized that Mu Xueran was answering the question he had just asked.

Xu Qing said in his heart: It's good if you don't have a boyfriend, so that you have a chance.

"Is she from our school?"

Mu Xueran shook her head, "No, she is an exchange student, in country F." ”

"When is that going to end?"

"One year to go. ”

"What school was she originally in?"

"A city A big. ”

Hearing this, Xu Qingrang lowered his eyelids and thought: That girl is not in China, won't he be able to see her?

All in my mind was that soft and delicate little face, for a while, Xu Qingrang raised his eyes, with a touch of firmness in his eyes, and thought: It's a big deal to use mobile phones to get familiar with each other first, and when she returns to China a year later, she will go to A University to find her every weekend.

"Hehe, Yukizome, what's her name? and can you give me her contact information?"

Mu Xueran thought to herself: Anyway, she has already sold Mengxin, and it is nothing to sell another Nuan Nuan.

So, Mu Xueran took out her mobile phone, opened WeChat directly, clicked on Lu Zhinuan's avatar, and recommended her to Xu Qingrang.

also typed three words and sent them to Xu Qingrang.

"Alright. Mu Xueran shook her phone.

"Thank you. As soon as the words fell, Xu Qingrang quickly got up and returned to his position, took out his mobile phone from the hole in the table, and clicked on the WeChat message sent by Mu Xueran.

The three words "Lu Zhinuan" are personal business cards, which read "Three Winter Warm".

"Lu Zhinuan, Lu Zhinuan. Xu Qingrang thought silently in his heart, he thought, listening to the name, he knew that she must be a very gentle girl.

Click on the personal business card, add it to the address book, stop your fingertips on the "Send Add Friend Request" column for two seconds, return to the original interface, and change the WeChat name to "Spring Cold".

Xu Qingrang stared at the new WeChat name, smiled a little stupidly, and then went to send a friend application to Lu Zhinuan.

......

On the other side, Ren Mengxin heard the conversation between Mu Xueran and Xu Qingrang clearly.

Looking at Xu Qing's anxious back, Ren Mengxin poked Mu Xueran's arm and said, "Xueran, I also want to ask you something." ”

"What's the matter?" asked Mu Xueran.

Ren Mengxin leaned over, leaned on the table, turned her head to look at her, and blinked, "As for the boy I told you before who added me to WeChat and confessed to me, he said his name was Zhao Cheng, I thought about it, isn't he the boy we went to eat noodles together that day and was opposite us?"

Ren Mengxin moved towards Mu Xueran again, and continued: "I remember you also told me that he is Duan Hanyu's good brother, and he also calls you 'sister', you said that the two of you are also familiar with each other, and it is normal to have a contact information, no matter how bad Duan Hanyu's contact information, you should have it, so ......"

After a pause in his tone, Ren Mengxin straightened up, patted the table, and pretended to be serious: "Say, did you tell me my contact information?"

"......" Mu Xue said in her heart: Don't look at Meng Xin's usual nervousness, her ability to analyze problems is quite strong.

Nodding his head, he admitted it, Mu Xueran explained: "It was Duan Hanyu who asked me for it, I think you don't complain every day that no one is chasing, what a good opportunity, isn't it?"

As she spoke, Mu Xueran raised her eyebrows.

Hearing this, Ren Mengxin actually blushed a little embarrassed.

After all, it was the first time she had been confessed when she grew up, and Zhao Cheng would chat with her every night, she had slowly formed a habit and had a good impression of Zhao Cheng.

Although Ren Mengxin always said that she wanted to fall in love, when she really came to her, she would retreat because she was shy and embarrassed.

Mu Xueran chuckled, "You can talk if you want to, you can give each other a chance to try first, maybe he is your Prince Charming?"

Ren Mengxin covered her face, and for a long time, she looked at Mu Xueran through her fingers and nodded.

............

At noon, after lunch, Mu Xueran went to the 708 laboratory, and only Wu Zixing was there.

Pulled a chair and sat down, and listened to Wu Zixing: "I just sent a message to the two of them, and I'll be here in a while." ”

"Well," Mu Xueran nodded, "Have you been to 709?"

"Not yet, but I went over yesterday morning to take a look, and it should have been a success. ”

"That's good. ”

The pre-experiment is mainly to determine the most suitable concentration of the bacterial solution to observe the growth state of the colony, which is the most basic step, and if it fails, the follow-up work cannot be continued.

After waiting for about ten minutes, Zhou Ying and Qu Xiaolin also arrived.

Zhou Ying put down her schoolbag and said to the three of them: "Put on the lab coat, let's go to 709 first." ”

......

709 Public Laboratory.

Mu Xueran put her hands into the latex gloves of the anaerobic incubator, carefully picked up a petri dish in the middle, looked at the other nine, turned her head and said, "This is P6, that is, the concentration of ten to the minus sixth power." ”

"What about P5 and P7?" Qu Xiaolin asked.

Mu Xueran picked up the Petri dishes labeled P5 and P7 respectively, and compared them with P6, "The colonies of P5 grew a little densely, and P7 was too scattered and did not grow a few." ”

Zhou Ying nodded and said, "You take the snow dye one by one, and I'll take them all down first." ”

Suddenly thinking of something, Zhou Ying patted her head, "Oops, we did a pre-experiment before, and I forgot to take a picture." ”

"Remember to shoot it when you start the experiment, and you have to repeat the pre-experiment process again anyway. Qu Xiaolin said.

Zhou Ying said "um", "That's the only way." ”
