Qi Yue didn't care what Qianjintang looked like from the outside. Instead, she became more and more quiet doing what she should do, teaching and studying.

"We still need to post these advertisements." Hu San asked, "No one seems to want to see them..."

"But there are still people who will read it after all." Qi Yue said, pushing the paper over, "It's hot summer now, when germs are easy to breed, so you should pay more attention."

Hu San nodded.

"Speaking of bacteria, Master, what about that Penicillium you grow over there?" he asked.

"It's almost a week, I'll go take a look soon." Qi Yue said.

"Then I'll inform the people in the experimental class to prepare." Hu San said.

Extraction of penicillin was regarded as a pathology course by Qi Yue, and his disciples also regularly participated in the whole process.

When everyone arrived at the Wang family's manor, the tools Hu San asked the craftsmen to make had just arrived.

Looking at those strange porcelain pots, barrels and shelves, the farmers in the garden were very curious, but they did not dare to come forward because the owner had told her that Mrs. Qi was doing something very important and must not be disturbed.

But they didn't dare to come forward when they listened to their master's words. There were still some people who didn't listen to their master's words and came forward.

"Is this for bathing?" Wang Qiaoer asked, patting a wooden bucket and reaching out to grab the cork underneath, "What is this for..."

Qi Yue came over and took her aside.

"Why are you such a naughty kid here again?" she asked, frowning.

"This is my home!" Wang Qiaoer said with a snort.

"It's mine now." Qi Yue said, carrying her out and calling someone.

Several maids hurried over and looked at the young lady who was casually grabbed by Qi Yue like a little chicken.

"It's really hard to have fun here." Qi Yue said to them, "I will get pathogenic bacteria in a few days. If I accidentally get infected, it will cause death."

The servants turned pale with fright and hurriedly pulled Wang Qiao away.

"Auntie." Another child's voice came.

Yan'er, wearing new clothes, ran over like a butterfly. Sure enough, when she saw Wang Qiao'er, she immediately stared with eager eyes.

Look, look, she said she had to come, otherwise her aunt would be snatched away by this nasty guy.

Qi Yue patted his head.

"Auntie, you are busy. I won't disturb you. I'm going to pick fruits in the garden. Can I come back after you're done?" Yan'er said obediently, with a bit of pity, "Auntie, I haven't seen you for a long time.

Already…”

Qi Yue raised his hands in surrender.

"Okay, go ahead." She said, telling her not to go near the house here.

Yan'er nodded obediently.

"Why is she here?" Wang Qiaoer stared.

"Because she is more obedient than you." Qi Yue said.

Yan'er looked at Wang Qiao'er with a bit of pride.

"Go, let's play." Qi Yue patted her shoulder and walked away.

"It's my aunt." Yan'er said with a bit of showoff, and walked away proudly with the girl and servant.

"I'm not as good as this ugly bastard." Wang Qiaoer said, shaking her head, "Let's go, let's go too."

Qi Yue ignored the matter of the two children, put on lab coats, and everyone began to look at the Penicillium in the petri dish.

Because it was an experiment, every disciple did it. There was a table full of people, everyone looked at their own, and there were exclamations and laughter from time to time in the room.

"Okay, okay, now prepare to filter." Qi Yue stopped everyone from joking and clapped her hands and said.

The disciples took out the improved cotton cloth filled with filter cotton that was placed on the shelf.

Extract in a pear-shaped porcelain bottle and add charcoal powder.

Because it was an experiment, all the disciples watched Qi Yue's demonstration and did it together.

"...Add distilled water first..." Qi Yue said while pouring the distilled water in.

Because of the traditional Chinese medicine extraction injection, distilled water is familiar to everyone.

Qi Yue walked around in a circle, instructing everyone to stir, while explaining the principles. As for the purification of penicillin, she didn't care much, she was more concerned about treating this as an experimental class.

"Master, should you put the vinegar water or seaweed water first?" a disciple asked.

Qi Yue looked at the others.

"I've told him several times, who will tell him?" she asked with a smile.

A disciple immediately answered with a smile.

The experiment was conducted in a relaxed atmosphere.

"Master, is this the kind of penicillin that can quickly kill bacteria?" The disciples looked at the small tubes in their hands and asked in disbelief.

The penicillin solution extracted by everyone was placed in small, slender porcelain bottles. Hu San asked the craftsmen to imitate Qi Yue's syringes and fired white porcelain test tubes. They were also marked according to the scale on the syringes.

, just used to hold the dose of penicillin.

Qi Yue also looked at it with her own, feeling an indescribable feeling.

This is...penicillin?

Is it that simple? Is it really possible?

"Whether it has any effect depends on the next test," she said.

"How to test it?" the disciples asked.

"Be careful these days. If you have patients with sores, boils, inflammation and pus, you can collect the pathogenic bacteria." Qi Yue said.

Look at the sky outside, it's already past noon.

"Okay, okay, today's class is over. Let's pack up and get ready to go back." She clapped her hands and said.

Qi Yue washed her hands, sanitized her hands, changed her clothes and walked out, then she remembered that there were two children here.

"Have you left already? It's hot and stuffy here, and it's past dinner time. What child can bear it?" She muttered as she walked along the road and just reached the orchard.

"…This is my home!"

"...I picked this first..."

"...Hey, hey, please call me Miss. If you have something to say, don't do anything."

"...Who are you talking about? Just mind yourself first..."

Qi Yue shook her fan and shook her head.

It was still very cool by the pond. When Qi Yue was preparing the barbecue, Wang Qiao and Yan'er also came over after freshening up.

"Look, it's so clean and beautiful." Qi Yue said with a smile.

Yan'er clutched her pigtails with a bit of pride, while Wang Qiao'er on the side gave her a blank look.

"It's not about you, you are not beautiful no matter how clean you are." She said.

"Hey, Miss Wang, it's time for you to go back." Qi Yue said.

Wang Qiaoer looked at the meat skewers sizzling on the barbecue grill.

"This is me..." she said.

"This place is mine now, and I paid for it." Qi Yue interrupted her and extended his hand to her, "Miss, I, the master, have to see off guests."

Saying this, he shook the grilled meat skewers towards Yan'er.

"Come on, Yan'er, you're so hungry, let's have a taste." She said with a smile.

Sure enough, her aunt loves her the most! Yaner passed away happily.

Seeing the ugly girl eating so deliciously and her own lady standing aside in embarrassment, the servant girl couldn't help it anymore.

"Ms. Qi, you're a kid, don't be like this," an older one said with a smile.

"Why not?" Qi Yue looked at her, as if strange, "She doesn't like me, and I don't like her either. Besides, she's not hungry, so why should I treat her to food?"

what…

The servant girl was speechless.

After all, Wang Qiaoer didn't eat anything, so she got home in the car angrily and went straight to Mrs. Ning's place.

"Grandma," she shouted, throwing herself into Mrs. Ning's arms, "find daddy and come back!"

Mrs. Ning smiled and pulled her up to sit down.

"What's going on?" she asked, "Didn't you go to live in the country with your great-grandfather? Why are you looking for your father again?"

Wang Qiaoer was too lazy to say anything, so he grabbed some snacks on the side and ate them.

"Hurry up and find Daddy." She said, following Yan'er's fuss for a long time. She was so hungry that she kept her heart in mind and murmured as she ate.
