The power of the Mason nobles was repeatedly attacked by Arrod, and since then it has collapsed, and no one has questioned Arold's regency to Mason, Arold has re-sent his own officials to manage it, but the momentum of the plague shows no signs of abating, and people can only wait slowly and patiently.

After more than a month, Arold walked out of the prayer room as usual, as a lord it was necessary for him to pacify the people in this way, and moved the ruins of the Virgin to the castle, although Arold knew that it was just a forged relic, but the others did not, and the nobles in the castle asked the monks to carry the reliquary every day and patrol the castle for a week to be at ease.

"What a stupid fellow, the real holy relic is not that ornate wooden cabinet." Standing in the corridors of the castle, Arold looked out of the window, and saw the monks in gray robes, carrying reliquaries covered with gold leaf, kneeling everywhere they went, nobles and commoners, praying for peace.

Arrod's gaze looked beyond the parade of relics to the bakery in the corner of the castle, and the people began to wonder why there were swordsmen guarding it, but when the plague intensified, no one bothered with such idleness, they did not know that the real relics were in the bakery.

"Lord Duke, another knight has been infected with the plague and died." Dylan. Matt staggered over to Arrode, to whom he reported.

"Got it, let's do as usual." Arold pursed his lips and said, in order to reduce the spread of the plague, the Teutonic Knights and the Mecklenburg legionnaires are not allowed to go out in their respective camps, and the dead knights will immediately dig deep holes in remote parts of the territory and bury them. Therefore, the bones cannot be damaged.

"Our forces have been greatly reduced, and God willing, we have no external enemies at this time." Dylan. Matt said.

"The knight didn't die on the battlefield, but died on the sickbed, what a waste!" Arold said distressedly, anxious to see how penicillin was made. Even risking it on knights and soldiers is better than doing nothing and watching them die.

Thinking of this, Arold walked out of the main tower alone and walked towards the bakery, he wanted to see how this secret elixir from the future was developed. When he appeared in front of the bakery, the swordsmen who were guarding it quickly stood up, and it was usually a remote and mysterious place, except that Miss Shirley sometimes asked them to help carry some bottles and cans, almost none of them came out.

"Lord Duke."

"Are they there?" Arold was overwhelmed by the plague, and he felt that it was more terrible than fighting. The invisible and untouchable virus follows the Grim Reaper like a shadow.

"Yes." The swordsman opened the door for Arold to enter, and the wooden door creaked, and Arold nodded and walked into the room.

Arold walked into this originally ordinary bakery, only to see that the wooden shelves where bread was originally placed in the bakery were full of all kinds of clay pots, which were also hard-won, and Arold used his authority to collect the clay pots of all the people in the castle, so there were many people complaining behind their backs.

"Ahh Lord Duke? Leila, who was rolling up her sleeves and working, suddenly saw Arold and said in surprise.

She was now flipping open the lids of the clay pot one by one. It is an extremely tedious process to observe the growth of Penicillium inside, that is, to collect the mold on the nutrient-rich fruit, drip it into a liquid rich in oil and starch, stir it and incubate, and after a period of time, observe whether the antiviral status will appear.

"Well, did the situation I said come about?" Arold asked anxiously.

"I'm sorry Lord Duke. Not yet, we have tried the method you taught us repeatedly, but it didn't work at all, are you sure this method works? Leila said apologetically, a little skeptical that Arold's method was working. They were like building a castle out of sand on the beach, full of hope every time, but when the results were revealed, they were greeted with only one disappointment.

"Don't be discouraged, I'm sure it will work." Arold stepped forward and patted Leila's shoulder, although he was encouraging Leila, but Arold himself was not sure in his heart, after all, this was more than 2,000 years ago from modern technology, and Leila and Shirley had no medical training, they were completely relying on their feelings to explore, and with the guidance given by Arrod, a half-traverser.

"Lyra, Lyra, come on." Suddenly, in the room inside the bakery, Miss Shirley's excited exclamation was heard, and when she heard Miss Shirley's exclamation, Leila's expression changed, and even Arrod felt short of breath.

"Here it is, Miss Shirley." Layla and Arold immediately walked to the room inside, not even bothering to bump into the wooden table along the way.

"Come and see, is this the Duke, uh, the Duke." I saw Miss Shirley, who was unkempt in the back room, was excitedly uncovering a clay pot on the wooden table, and when she looked up, she happened to see Arold also appear here, and couldn't help but be a little surprised, she was too focused on the experiment.

"Let me see." Arold hurriedly walked over, looked down at the situation in the clay pot, and saw that in the center of the mixture of starch and oil, a small dot appeared in the place where Penicillium was originally all over, and Penicillium around it retreated as if it had encountered resistance.

"Is that it?" Lyra asked curiously.

"Yes, this is penicillin, also called penicillin, it's done." Arold slapped his thigh excitedly, he couldn't contain the joy in his heart, this thing was more precious than gold, you must know that almost all diseases in this era can be cured, tetanus, which has the highest mortality rate in war, can be cured.

"Great, it didn't work in vain." Miss Shirley wiped the sweat from the back of her hand, and a happy smile appeared on her face.

"Okay, the next step is to extract penicillin, and I asked the people in the smelting base to make this." Arold took out a small round copper bucket like a trick, and then pulled it out, it was actually a dropper, of course, the modern rubber end is made from the cow's milk/head, fortunately there are also leather craftsmen in the smelting base.

With the efforts of Miss Shirley and Leila, the first penicillin of this era was made, although Arold didn't know whether it was right or not, but he finally felt that in the face of the most terrible disease of this era, he no longer looked like a warrior who went to the battlefield without weapons, and his weapons on the battlefield were excellent swords, and penicillin would be his weapon and source of wealth in this invisible battlefield.
