Qian Xingshan was not stupid either. He had learned a few things by following Dong Mingshan.

After the initial frenzy, he now calmed down.

Thinking back on the questions my sister and mother asked these days, they were actually full of deep meaning, but I didn't hear it at the time.

He smiled bitterly and stood up.

Lu Lin looked at him nervously, "Brother Xingshan, are you ready now?"

Qian Xingshan shook his head. "Forget it. Have a good rest today and we'll talk about it tomorrow morning."

After saying this, Qian Xingshan went to the inner courtyard. He planned to admit that he was wrong and he needed manpower.

In the backyard, Qian's mother walked anxiously, looking back as she walked, wanting to see if her stupid son would come to ask for help.

"Chunhua, do you think Xingshan will come to seek help? He won't be stupid enough to carry it all by himself, will he?"

"Don't worry, if he is really stupid enough to handle it all by himself, then he might as well stop doing business because he will tire himself to death sooner or later."

This time, Qian Chunhua wanted to see if his brother could figure it out.

If he relies on himself to do everything, not only will his business not grow big, but he might even work himself to death.

Qian Chunhua didn't give up. Within a quarter of an hour, Qian Xingshan came to find them.

Seeing her younger brother appear in front of her, Qian Chunhua breathed a sigh of relief. She was really afraid that he was a stubborn person.

"Hehehe, Mom, sister, I was wrong." Qian Xingshan's first words were to admit his mistake.

Qian's mother said with heartache, "You finally figured it out, kid."

Qian Xingshan nodded seriously, "Well, don't worry, I've figured it out."

"What are you going to do?"

Qian Xingshan said seriously, "Have a good rest tonight, sister. Tomorrow morning you can lend me ten people, including the cook and the maid. I want them all.

First prepare the braised pork that will be needed for the store tomorrow. Tomorrow afternoon, I will find time to go to the dental clinic and buy two servants."

Qian Chunhua nodded. His brother said that there were solutions to the problem and also preventive measures for the problem. Although they were not perfect, they could temporarily solve the current problem.

"Okay."

This time, Qian Chunhua was really relieved. His brother was no longer the country boy from Huang Lingling who knew nothing. He also began to think about problems and began to consider using manpower to help him do things.

This is a good start.

In the following days, Qian Chunhua no longer paid attention to the situation of her brother's braised meat shop. She devoted herself to her own experiment.

Finally, ten days later, she received a small porcelain bottle of penicillin.

Looking at the familiar powder, Qian Chunhua breathed a sigh of relief. Next, it was time to test the efficacy of these powders.

After collecting all the records in the laboratory, Qian Chunhua hid them all in the space.

She knew that the discovery of penicillin would be a great revolution of this era.

Before this, many diseases caused by bacteria, such as pneumonia and sepsis, were often untreatable, resulting in the loss of countless lives.

But now, with the emergence of penicillin, this situation will change, bringing hope of survival to countless patients.

But Qian Chunhua would not make such a precious drug public directly. At least for the time being, he would not let people in this world abuse antibiotics like he did in the world before he traveled through time.

Qian Xingshan's braised meat shop was busy and chaotic at the beginning, but now it is in perfect order.

He hired six servants, two of whom were responsible for cleaning pork and offal, with the daily cleaning volume reaching a steady 100 kilograms.

The two of them were responsible for making the braised meat. As for the recipe for the braised meat, he followed his sister's advice and prepared the marinade himself, then wrapped it in gauze. He put the marinade in every day and collected the marinade bag after finishing.
