In the end, he used a total of 15 small tripods to hold the penicillin solution.
Li Wenshi shouted, "Come here, bring the boiled and sterilized carbon powder over here."
"Da da da..." The two medicine boys hurried to move things.
The two put the carbon powder on the table, and Li Wenshi continued his experiment.
He poured the penicillin solution into the jar of carbon powder, stirring it as he spoke. "This step is to extract the impure substances in the penicillin. The penicillin solution will be absorbed by the carbon powder."
After stirring, Li Wenshi put the carbon powder that had fully absorbed the penicillin solution into the experimental container they brought.
Then, Li Wenshi added boiled pure distilled water. He said to the crowd, "By adding distilled water, the impurities in the penicillin solution will be washed out."
Li Wenshi looked at Cheng Xiaoxiao and said, "Girl, give me a bottle of vinegar and some baking soda."
Cheng Xiaoxiao took out a bottle of Shanxi aged vinegar and a packet of baking soda and handed them to Li Wenshi, thinking to herself, "You have oil and vinegar here, someone who didn't know you would think you were cooking!"
Li Wenshi took it and poured aged vinegar into the experimental container. "Penicillin is a weak acid and will not dissolve in acidic water. By following the above steps, we can further remove the alkaline impurities in the penicillin solution."
He asked someone to bring a basin of water and added baking soda to it to make soda water.
Li Wenshi picked up the soda water and slowly poured it into the container. "Now add the alkaline soda water, and the penicillin will dissolve from the carbon powder."
As he spoke, the doctors at the Imperial Medical Bureau saw a clear liquid flowing out from the hose at the bottom of the container.
Everyone looked at the liquid flowing out of the hose with happy expressions on their faces.
It looks like we can succeed this time, right?
"We must, must succeed!" they thought to themselves.
Under the gaze of the crowd, Li Wenshi picked up the small tripod filled with penicillin solution and said to them with a smile, "This is the higher-purity penicillin solution, but we still need to verify whether it was produced successfully."
Li Wenshi said to Lao Yuan from the medical team, "Lao Yuan, please help me get the Staphylococcus culture dish out."
Old Yuan said "hmm" and went to get the Staphylococcus culture dish.
Li Wenshi opened the petri dish, dripped a drop of penicillin solution into it, and then closed the lid. He said to the crowd, "Now all the steps are complete. We just need to wait for two more days to know whether the penicillin solution is successful."
"As for how to tell if it's successful, we'll know once we open the lid. If there's no change in the petri dish, then our penicillin has failed. Conversely, if a circle appears around the spot where the penicillin solution was dropped into the dish, then the penicillin solution has driven away the Staphylococcus, and our creation has been successful."
Li Wenshi handed the culture dish to Lao Yuan, who took it and put it back in its original place.
Li Wenshi clapped his hands and said to everyone, "Now let's look forward to it!"
The imperial doctors nodded.
They were naturally looking forward to it, but they couldn't help but feel a little worried.
This thing must be successful, otherwise all their efforts will be in vain.
…
On the way back, Cheng Xiaoxiao asked Li Wenshi, "Mr. Li, how confident are you about penicillin?"
Li Wenshi thought for a moment and replied, "80%, and the remaining 20% can only be left to time."
"Yeah, you will succeed." Cheng Xiaoxiao cheered.
The three of them separated at a fork in the road, and Cheng Xiaoxiao returned to her palace.
From a distance, she saw two slim figures in front of the palace gate.
When she got closer, she found that they were two palace maids.
The two of them bowed to Cheng Xiaoxiao, "Your servant Yinqiao and your servant Yinhua greet Princess Xingguo."
After a little guess, Cheng Xiaoxiao knew that these two palace maids must have been sent by the First Emperor to serve him.
Cheng Xiaoxiao nodded slightly to the two of them, "Stand up, no need to be polite."
"Yes." Yinqiao and Yinhua stood up obediently.
As soon as Cheng Xiaoxiao returned to the room, she pulled Cheng Mianmian out and asked, "Mianmian, have you prepared the information?"
Cheng Mianmian looked at her with resentment, "Master, I'm done here. Can you let me count those Qin Banliang again?"
Cheng Xiaoxiao shook her head and laughed, "How many times have you counted? Are you not tired of it yet?"
Cheng Mianmian pouted and said, "No, actually I just like the process of counting money."
Cheng Xiaoxiao: "As long as you help me print out all the information, I will let you go and play."
Cheng Mianmian nodded repeatedly, "Okay, Master."
Cheng Xiaoxiao moved the printer and A4 paper into the space. She looked at Cheng Mianmian and encouraged her, "Good Mianmian, you have to work hard! Think about the money."
Cheng Mianmian nodded vigorously again, "Don't worry! Master, I will do my best."
Cheng Xiaoxiao stopped talking and focused her attention on the outside world.
In order to count her lovely money as quickly as possible, Cheng Mianmian began to work hard.
Fortunately, everything she needed was in the space, so Cheng Mianmian didn't have to move it around. As soon as she thought about it, the printing paper automatically appeared in the printer box.
"Buzz buzz buzz..." The printer started working and each piece of information was printed out clearly.
Outside space.
Cheng Xiaoxiao had just picked up the teacup and took a sip of tea when she saw Yinqiao hurriedly coming in with small steps.
She put down the teacup and asked, "What's the matter?"
Yin Qiao bowed respectfully, "Your Highness, the Secretary has arrived with His Majesty's reward."
Cheng Xiaoxiao hurriedly said, "Please invite Secretary Qi in."
"Yes." Yinqiao turned around and walked out the door quickly.
When Qi Yuan came in with the reward, Cheng Xiaoxiao was already standing in the hall waiting.
Qi Yuan bowed and said, "Greetings to Princess Xingguo."
Cheng Xiaoxiao: "Secretary Qi, please don't be polite."
Qi Yuan stood up and said to the back, "Bring up the reward that His Majesty gave to Princess Xingguo."
As soon as he finished speaking, Cheng Xiaoxiao saw eight palace servants who looked like eunuchs walking in carrying four large boxes.
Qi Yuan waved to the four people, and the four people saluted and left.
He looked at Cheng Xiaoxiao and said in a deep voice, "Your Majesty has an order!"
When Cheng Xiaoxiao was still wondering whether she should kneel, she heard Qi Yuan say, "His Majesty said, you don't have to kneel."
Cheng Xiaoxiao: Our ancestors were considerate and knew that I didn’t like the ritual of kneeling and bowing.
Qi Yuan quickly read out the Emperor's edict and handed it to Cheng Xiaoxiao. He looked at the boxes and said, "There are a total of 10,000 taels of gold in here, all for you, Princess."
Cheng Xiaoxiao was stunned when she heard this. "Ten thousand taels... of gold?"
"Yes." Qi Yuan lowered his voice and said, "Your Majesty was originally hesitant about how to reward Princess Yu. Later, General Meng Tian told Your Majesty that you like silver and money, so Your Majesty rewarded you with 10,000 taels of gold."
