Aryra's expectant eyes made Arold fidget, and although he only comforted Lyra with words, Arold quietly called Lyra to the conference hall after the courtiers had left after the courtiers' meeting was over.

"Lord Duke?" Leila fidgeted in the chamber, where important matters were decided in Mecklenburg, the guards at the door holding halberds with serious expressions.

"Wait a minute, there's an important member." Arold sat down in his chair and said to Lyra.

"I don't know what I can do for you?" Layla said uneasily.

"Keep your enthusiasm going." Arold smiled slightly, and he poured a glass of wine for Leila to relax a little.

"Lord Duke, are you looking for me?" At this moment the door opened, and Miss Shirley entered, her hair disheveled, tired and haggard, and her clothes stained with dirty plant juice.

"Miss Shirley hasn't found a cure yet?" Arrold told Miss Shirley that after the outbreak of dysentery, Miss Shirley had been researching the treatment potions in the pharmacy, but it didn't seem to be going well at all.

"Lord Duke, I'm sorry that I used all my methods and knowledge, but to no avail." Miss Shirley reached out in frustration to remove the bangs from her forehead, she didn't expect that this dysentery epidemic would be so tricky, and if it wasn't for Arrod's precautions, I was afraid that more people would die.

"I see, it seems that the knowledge of this era cannot be solved." Arold rubbed his temples, he didn't want to borrow knowledge beyond the times to solve this matter, so as to prevent too advanced technology from disrupting the course of history.

"Do you have a way?" Leila and Miss Shirley spoke in unison, and looked at Arrod incredulously, especially Miss Shirley, who couldn't believe it.

"Yes, but I want you to keep it a secret. You can't leak it out without my permission. Arold said earnestly to Layla and Shirley.

Arold knew that the only way to eradicate the terrible poison of dysentery was to use a more powerful medicine, which was penicillin, but fortunately he had watched a time-traveling drama and studied the feasibility of it, although he didn't know how far it could be done in this era of rudimentary equipment. But it's really worth a try at this point.

In fact, there was penicillin in the Tang Dynasty: as early as the Tang Dynasty, the tailors of Chang'an City would put the paste with green hair on the fingers cut by scissors to help the wound heal, because the substance produced by green hair (penicillin bacteria) had a bactericidal effect, that is, people first used penicillin. Modern penicillin was developed in 1941 by Tang Feifan, a famous microbiologist from the Central Epidemic Prevention Laboratory, during the Anti-Japanese War.

In fact, penicillin can also be made by hand in the following ways:

This method has been affirmed by medical experts.

1。 Use the sap partially ground from the tubers of rice plants as a medium solution (in a small bowl)

2。 Transplant Penicillium into it (Penicillium is to find a food that has become moldy, and scrape off the moldy material on it), and wait for 1 week...... In cultivation

3。 Take a small crockpot. Seal the top with special Mecklenburg paper (do not use a lid), cut a small hole in the film and take a funnel. Sterilize the cotton wool in the funnel and pour the cultivated liquid from the cotton wool. (sort of like filtering)

4。 Pour an appropriate amount of olive oil (3 times the culture medium) into that crockpot and stir.

5。 At the end of the stir, you will find that there are 3 layers of liquid in the jar.

6。 At this time, use a small spoon to slowly remove the oil and grease from the upper layer! (I believe you still know what is oil and what is.)

water), leaving only the water at the bottom.

7。 Add the toner (take it yourself) to the jar and stir.

8。 The carbon will absorb Penicillium components, and the liquid in the jar will be sucked dry.

9。 Remove the carbon. Wash the carbon with distilled water, note. A little bit is fine.

10。 Wash the carbon with distilled water.

11。 Wash with seaweed juice

12。 Repeat the method in step 3 (buy another crockpot or glass) and strain

13。 DIVIDE THE FINAL RESULTING LIQUID INTO SMALL CUPS PER 100 CC. Wait a few days (about a week)

14。 The last step is more difficult, dip a cotton wool swab in a little and drip it in the center of the small cup

15。 Await......

16。 After a week, if you see that there is no Penicillium in the center, only a ring around it, it is made

17。 Use a glue-tip dropper to aspirate Penicillium in the ring. It's penicillin!

Miss Shirley was dumbfounded as Arrod explained the method of making it in detail, she had never been exposed to such advanced pharmaceutical methods, and just listening to the process was enough to make people jaw-dropping.

"Lord Duke, where did you hear about this method?" Miss Shirley stammered.

"Leave it alone. It will be God's will, and I will prepare everything for you, and all you have to do is to keep up your duties as a pharmacist, and help me to make this healing potion. Arold said to Miss Shirley.

"Okay, it's worth a try." Miss Shirley was eager to try it, and as an inquisitive witch, she was eager to experiment with penicillin.

"Duke, Lord Duke, please use my bakery! I also want to do my part for the patients. Leila also said excitedly.

"Yes, but you must remember that the method of making this medicine must be kept absolutely secret, and I will send a team of swordsmen to protect you." Since Arold is absolutely making penicillin, he has to do it successfully, after all, Mecklenburg is the territory he has worked so hard to build, and it is his homeland.

"Quick, keep around." Soon, the nobles of Mecklenburg saw a group of heavily armed swordsmen surrounding Leila's bakery in the castle, and Miss Shirley moved in with many bottles and cans.

"What has Arrod been doing lately?" Princess Josie and her maid walked in the corridors of the castle, and through the window you could see Leila's bakery, which was guarded by soldiers in iron armor and large swords, and they received orders from Arold to protect the people and things inside, and no one was allowed to approach without Arold's warrant, and if anyone trespassed and killed.

"I don't know, but I often see the Duke often going to the bakery." The personal maid reports to Princess Josie.

"When will this terrible scourge end?" Princess Josie said worriedly.

"Yes, it's terrible to hear that the town outside the castle is dying every day." The maid said in a frightened tone.

"Bell~~." When the church bell rang, people looked at it when they heard it, and when the bell rang, people died, and as many people died as they struck, and the bell rang like a nightmare in everyone's heart. (To be continued.) )
