Then, Mu Xueran took out a large white plastic bottle and handed it to Qu Xiaolin, looked at the record in the notebook and said, "Peptone 0.1 gram." ”

......

"This magnesium sulfate heptahydrate needs 0.02 grams, how do you call it?" asked Qu Xiaolin.

Because ordinary electronic balances are accurate to one decimal place, weighing 0.02g requires a more precise instrument.

Hearing this, Zhou Ying pointed to an instrument covered with a transparent plastic box next to him and said, "With this analytical balance, it can be accurate to 1/10,000." ”

"Come on, you can help me weigh it. ”

Mu Xueran nodded, took the bottle in her hand, and walked to the analytical balance with a weighing paper and a small medicine spoon.

Fortunately, she used an analytical balance in chemistry experiments in high school, took off the transparent cover, turned on the power, and waited for the display to show 0.0000g, then opened the door on one side of the balance, put the weighing paper on it, and then pressed the "Tare" button to peel it.

......

The reagents are weighed, and then 100 ml of deionized water is added to each serving in an Erlenmeyer flask to dissolve.

After a while, Qu Xiaolin raised the Erlenmeyer flask to look at the sunlight and said, "I've been shaking it for a long time, and there are still some solids that are insoluble." ”

Zhou Ying wrapped the last pipette tip box, marked it with a marker, and said, "It's okay, it will be sterilized for a while, and it will naturally dissolve at high temperatures." ”

"Oh, that's good. ”

"Can you add agar?" Zhou Ying asked.

Mu Xueran nodded and said, "Plus." ”

Zhou Ying said: "Well, there are tampons and newspapers in the drawer, you two can wrap the Erlenmeyer flask as well." ”

...

After the preparations were done, Zhou Ying opened the lid of the autoclave and put all the instruments and reagents needed into the iron basket inside.

"Check again, two bottles of medium, 10 ml centrifuge tubes, three models of tips, Petri dish ......"

Suddenly thinking of something, Zhou Ying patted her head and said, "By the way, the dilution of the bacterial solution requires the use of deionized water, and it must also be extinguished by 100 ml." ”

"I'll pour it out. After speaking, Wu Zixing took a clean Erlenmeyer flask, took 100 ml, wrapped it, and put it in the sterilizer.

“OK。 ”

Closing the lid and turning the handwheel to tighten it, Zhou Ying squatted down, turned on the switch, and set the temperature and time.

"115 °C, 20 min. Zhou Ying got up and said, "OK, wait." ”

Mu Xueran took off her gloves, and after wearing them for a long time, her hands were a little white, and there was a smell of rubber.

frowned, walked to the sink, looked at himself in a white coat in the mirror, and Mu Xue hooked his lips.

I never thought that one day I would be patiently engaged in scientific research in the laboratory.

I squeezed some hand sanitizer, crossed my index fingers, and rinsed off the foam on my hands.

found a chair, and as soon as Mu Xueran sat down, Qu Xiaolin came over.

"Xue Ran, you know Senior Sister Xiaomeng. ”

"Well, she's my cousin. ”

"Huh?" Qu Xiaolin was a little surprised, and then whispered with a gossip on her face: "Teacher Yu Yang, do you know? I heard that they are husband and wife, is it really fake?"

Mu Xueran smiled, "It's true." ”

"Wow, it's really enviable, Mr. Yu Yang is the most handsome teacher in our school. ”

Wu Zixing also spoke: "Our senior sister is also a big beauty. ”

Qu Xiaolin nodded and said, "So handsome guys and beauties are a good match." ”

Qu Xiaolin wanted to ask something, but Mu Xueran's mobile phone rang.

looked at the caller ID, it was Xi Shaoxun.

got up and said to Qu Xiaolin, "I'll go out and answer a phone." ”

After speaking, Mu Xueran opened the call and walked outside the door.

"Kaoru. ”

"Dye, are you in the apartment?"

Mu Xueran leaned against the white wall behind her and said softly, "No, I'm in the Shaw Building at school." ”

"Isn't there no class, what are you doing?"

"I participated in an academic science and technology competition and am now doing experiments. ”

"You're talking about a big challenge, so I didn't bother you. ”

"Nope. ”

"When are you finishing? Accompany me for a meal at noon, there is a surprise." ”

"I'm not sure when it's over, but there's time for lunch. Mu Xueran smiled and asked, "What surprise?"

"Well...... Keep it a secret for the time being, and you'll know when you get there. ”

Mu Xueran raised her eyebrows, "Okay, you can send me the location first, and I'll go over to find you when I'm done here." ”

"Okay, dear dyeing, see you at the party, Muma~"

Mu Xueran chuckled, "I'll see you at the party." ”

Hanging up the phone, Mu Xueran sent a message to Emperor Jiuxiao.

[Snow: I have an appointment with Kaoru, so I won't go back to eat at noon]

The Emperor Nine Owls are almost seconds back.

[Owl: [pitiful] [pitiful]]

Seeing the two tearful expressions in their eyes, Mu Xueran couldn't help but chuckle.

[Snow: You have to eat well, I may have to accompany Kaoru to go shopping, and I will go back later.] 】

[Xiao: Received, you also have to eat well and eat less unhealthy things]

[Snow: [uh-huh]]

......

Back in the laboratory, Mu Xueran glanced at the temperature on the display screen of the autoclave, 92 °C, and it was estimated that she would have to wait for more than half an hour.

Although the autoclave is set to sterilize for 20 minutes, the 20-minute timing starts from the temperature rises to the set 115°C, so the heating and cooling time after the temperature is not included, and the whole process takes about forty or fifty minutes.

At this time, Qu Xiaolin laughed twice, looked at Mu Xueran and blinked, and asked the question she wanted to ask before.

"Yukizome, do you have a boyfriend?"

“......”

Mu Xueran suddenly thought of Ren Mengxin, these two people must be able to talk together, they are all so gossipy.

"Yes. ”

Mu Xue said in her heart: For the time being, let's first wronged Emperor Jiuxiao to be demoted to her boyfriend.

Hearing this, Qu Xiaolin's black eyes flashed brightly, "Is it from our hospital?"

"It's not. ”

"Our school?"

Mu Xueran shook her head, "No, he's already working." ”

"Oh~" Qu Xiaolin said with an ambiguous face: "Then now you are responsible for being beautiful like a flower, and he is responsible for making money to support the family." ”

"Huh?" Mu Xueran raised her eyebrows, thinking that this sentence might be reversed, Emperor Jiuxiao is responsible for being beautiful like a flower, and she is responsible for asking for money to support her family.

I couldn't help but chuckle.

In the next second, the smile froze on her face, Mu Xue ran her eyes, and she suddenly thought of the conversation she had with Emperor Jiuxiao on the night of her grandfather's birthday.

"Emperor Jiuxiao, it's a pity that you don't go to be a chef. ”

"When the emperor goes out of business one day, maybe you can consider it. ”

"I can't bear it, if there really is such a day, I will raise you.

I'm serious, although I don't know how much money I have, but raising you and raising a baby is absolutely enough. ”

It was when she said "baby" that Emperor Jiuxiao's reaction was a little wrong.

She knew he was expecting the baby, but why?

What was the reason for the panic in his eyes and the emotion she couldn't understand?

And on the day he was discharged from the hospital, his eyes were slightly red, and he hugged her and said, "Mu Mu, I will never let you get hurt again." ”
