Ten days, ten whole days.
For the past ten days, he and Xu San's servant girls had been eating and sleeping together almost every day and night.
He cultivated the penicillin, then he purified it and made it into a dry powder, which was then sealed by Xu Miaoyun.
3,000 portions of penicillin, although the absolute amount was not much,
However, the details were definitely complicated.
They could find someone to cultivate the antibiotics, so it wasn't too tiring.
However, once it came to separating the two, it was an absolute technical task.
This step could only be Chen Shu's main force and Xu Miaoyun's assistant.
Then, he separated, purified, and made the penicillin into dry powder.
Without skilled workers, it was impossible to do it. Chen Shu focused on it, and the Xu family's girl was responsible for the other sundries.
In the past few days, even he, who had martial arts, could not withstand it, let alone a delicate woman.
"In the future, I can consider teaching her the art of purification!”
After ten days of getting along, Chen Shu had already confirmed that the Xu family's girl's character was useful. He even wanted to hit on her.
However, she would put this matter aside for the time being and wait for her father to return the money.
He couldn't let women delay the collection. This was Chen Shu's working principle.
He looked at the penicillin in his hand and smiled in relief.
It turned out that even in Da Ming's low-level craftsmanship, he could still produce good quality penicillin powder.
This was partly due to the system's prescription and partly due to Chen Shu's own efforts.
After he optimized the production process, he would probably be able to teach Xu Miaoyun.
If he hadn't really transmigrated, Chen Shu wouldn't have known that the method to produce penicillin was so complicated.
In the past, he had imagined that as long as he knew that he could cultivate the green mold through fruits, he could use charcoal, gauze, and vegetable oil to tinker with it to produce penicillin.
Only when he really came to Da Ming did he understand that his thoughts in his previous life were too naive.
He also understood why the ancestors did not discover the effect of penicillin.
Actually, this really wronged the old ancestor.
In fact, in the Tang Dynasty, there were documents about the use and discovery of penicillin. The reason why it was not used was probably because the ancients could not distinguish between the two.
The former was a toxin, while the latter was an antibiotics.
However, the two of them looked exactly the same.
This also meant that even if the ancients managed to cultivate penicillin, whether it was a poison or an antibiotics depended entirely on luck.
This was also one of the reasons why Chen Shu was not afraid of the production process of penicillin being spread.‘
Without his guidance, no one else could do it.
Moreover, even if they managed to isolate the penicillin, how could they preserve it? If they didn't make it into a dry powder and didn't have a suitable sealing technique, this thing could only be stored for three days at most.
After confirming that there was no problem with his craftsmanship, Chen Shu heaved a sigh of relief.
She saw that the wind was blowing in and Xu Miaoyun was a little cold. Chen Shu took off his cloak and put it on Xu Miaoyun.
Then, Chen Shu stood up and went to the next room.
As soon as he left, the girl from the Xu family opened her eyes and smiled.
Chen Shu's cloak was still warm, causing Xu Miaoyun's face to burn.
She did not know what she was fantasizing about and buried her head in the sofa in embarrassment.
"Old Xu!"
When Chen Shu walked out of the house, he found Xu San already waiting in the front yard.
The courtyard where he made the penicillin was an independent small courtyard. Xu San usually could not enter.
Beside Xu San was Zhu Mu, whom he had not seen for a long time.
Chen Shu saw Zhu Mu and Xu San chatting and shouted from afar.
"So Brother Zhu is here too!"
"You two are quite close!"
Chen Shu saw that Zhu Biao and Xu Da were quite familiar with each other and asked casually.
Zhu Biao and Xu Da instantly became nervous.
"No, Xu San sent me back last time, so I naturally have to thank him!”
Chen Shu did not doubt Zhu Biao's question.
"Chen Shu, I came today to invite you to my house as a guest!”
"My mother came from my hometown. The old lady heard that I have a good friend here, and she always troubles you!”
"That's why my mother prepared a family banquet. I hope you don't mind!”
Chen Shu had a good impression of Zhu Biao. When he heard that his mother had come from his hometown, he felt that he should pay a visit.
"Since your mother is here, how can Chen Shu not pay her respects?“
Zhu Biao was happy to see Chen Shu agree.
He had come today with a mission. Not only was Empress Ma here, but the Emperor was also at home.
"Uncle Xu, do you want to come for a drink?”
Zhu Biao turned his head and invited Xu Da. Xu Da did not fall for his trick.
He knew that Empress Ma was there, so he knew that the Emperor must be there as well.
This kind of family banquet was not comfortable to drink. Old Xu quickly shook his head.
"I have a business deal with Chen Shu today, and I still have to work for him?”
"By the way, Chen Shu, where's my daughter?”
Not only did Xu Da want to leave, but he also wanted to bring Xu Miaoyun along to hide.
"Miao Yun just fell asleep. I just covered her with the blanket!”
Chen Shu replied casually, leaving Zhu Biao and Xu Da dumbfounded.
What did he mean by just falling asleep? What did he mean by covering her with a blanket? What happened to my daughter?
Xu Da cursed in his heart. How despicable was he to mention Xu Miaoyun?
This time, even if his daughter was innocent, he could not explain it clearly.
Especially when he saw Zhu Biao's slightly awkward expression, Duke Wei felt that his daughter was getting further and further away from the position of the princess consort.
"I'll wait for Brother Chen at home!"
Zhu Biao coughed and turned to leave.
Xu Da was left crying.
"3,000 portions of penicillin are inside. Take it yourself!”
"Later on, you can exchange the money for the official notes of the Ministry of Revenue!”
Chen Shu gave Xu Da a few instructions and walked towards the backyard.
Since he was going to visit the other party's elders, Chen Shu felt that he should give him some gifts.
What should he give her?
He opened his system warehouse and found a bunch of things that he did not need.
What should he give the old lady?
Penicillins definitely wouldn't work. Who would give medicine to an old lady on their first meeting?
Perfume, no…
'Footstrong, this thing isn't easy to take out…'
Brain-brain gold, what kind of stupid thing is this?
Chen Shu's warehouse had all kinds of messy things.
In the end, Chen Shu found a copy of " Red Chamber " in the warehouse.
"Brother Zhu is educated and reasonable. Compared to his mother, he is also a daughter of a noble family!“
"A copy of 'Dream of the Red Chamber'!"
Chen Shu found a suitable gift and began to pack up to prepare for the banquet.
At this moment, Chen Shu was next door.
Zhu Biao bowed to his parents.
"Mother, Chen Shu has already agreed to attend the banquet!”
"Father, your secret room is ready. You can listen to us in the secret room!”
The Emperor nodded."
"Crown Prince, did you remember the question that Zhen asked you to ask?”
"Father, your son remembers!"
"Hmph, if this brat gives an answer that this one is not satisfied with, this one will definitely not let him off easily!”
The Emperor still wanted to put on airs, but was interrupted by Empress Ma."
"Go, go, go. He'll be here soon!”
"Why are you pretending to be a big wolf?”
"Sister, you…"
Although the Emperor was dignified, he could not get angry at Empress Ma.
He glared at Zhu Biao, who was holding back his laughter, and turned around to enter the secret room.
