The power of the Mason nobles was hit by Arod and never recovered from then on. No one questioned Arod's regent to Mason. Arod sent his own officials to manage it again, but the momentum of the plague showed no sign of weakening, and people could only wait patiently.

After more than a month, Arud came out of the prayer room as usual. As a lord, he had to comfort the people in this way and moved the remains of the Virgin Mary to the castle. Although Arud knew that it was just a forged holy object, others were not aware that the nobles in the castle required the monks to carry the holy lockers every day and patrol the castle for a week before they could feel at ease.

"What a stupid guy, the real holy thing is not that gorgeous wooden cabinet." Arod stood in the castle corridor and looked out from the window. He saw monks in gray robes carrying holy cabinets with gold foil. Wherever they went, nobility and civilians knelt down, praying for peace.

Arod's eyes passed over the holy relics and looked at the bakery in the corner of the castle. People began to wonder why there were swordsmen guarding it, but when the plague became more and more intense, no one was worried about such idle things. They didn't know that the real holy relics were in the bakery.

"Sir Duke, another knight died of the plague." Dylan Matt staggered to Arod, and he reported to Arod.

"I understand, do as usual." Arod said with his lips pursed. In order to reduce the spread of the plague, the soldiers of the Teutonic Knights and Mecklenburg Legion were not allowed to go out in their respective camps. The dead knights would immediately dig deep holes in remote areas of the territory and buried them. Originally, Arod wanted to burn them away with a fire, but Christian doctrine believed that people would be resurrected on the day of judgment. Therefore, they could not damage the bones.

"Our military resources have been greatly reduced. God blessed that we have no external enemies at this time," said Dylan Matt.

"The knight did not die on the battlefield, but died on the sickbed. It was a waste!" Aruod said with heartache. He wanted to see how the penicillin was made. Even if it was risky to use it for knights and soldiers, it would be better than to do nothing and watch them die.

Thinking of this, Aruod walked out of the main tower alone and walked towards the bakery, he wanted to see how the secret medicine from the future was developed. When he appeared in front of the bakery, the swordsmen guarding him stood up quickly. It was very remote and mysterious on weekdays. Except for Miss Shirley sometimes asked them to help transport some bottles and jars, almost no one came out.

"Duke."

"Are they here?" Aruod was in a state of turmoil because of the plague. He felt that this was even more terrifying than fighting. The invisible and intangible virus followed like a god of death.

"At." The swordsman opened the door and let Aruod enter. The wooden door creaked, and Aruod nodded and walked into the room.

Aroude walked into this originally very ordinary bakery and saw that the wooden shelf where bread was originally placed in the bakery was filled with various clay pots. These clay pots were hard-won. Aroude used his authority to collect clay pots from everyone in the castle, so many people complained behind their backs.

"Ah, Duke?" Leila, who rolled up her sleeves to work, suddenly saw Arod saying in surprise.

At this time, she was turning the lids in the clay pot one by one. She observed the growth of penicillium inside, that is, collect the mold on the nutritious fruit, drip it into oil and starch-rich liquid to stir and cultivate it. After a period of time, she observed whether there would be antiviral conditions. This is an extremely tedious process.

"How is it? Have you ever happened to what I said?" Aruod asked anxiously.

"Sorry, Lord Duke. There is no one yet. We have tried it repeatedly according to the method you taught, but it has no effect at all. Are you sure this method is effective?" Leila said with apologies, and she was somewhat doubtful whether Arod's method was effective. They seemed to be building castles with sand on the beach, and they were full of hope every time, but when the results were revealed, they only received disappointment again and again.

"Don't be discouraged, I'm sure it's useful." Aruod stepped forward and patted Laila on the shoulder. Although he was encouraging Laila, Aruod himself was not sure. After all, this was more than 2,000 years ago, and neither Laila nor Shirley had undergone medical training. He relied on his feelings to explore, and the guidance given by Aruod, a half-baked time traveler.

"Lilla, come Laila." Suddenly, Miss Shirley's excited scream came from the room inside the bakery. When Miss Shirley's scream was heard, Laila's expression changed, and even Aruod felt his breathing rapid.

"Here, Miss Shirley." Leila and Arod immediately walked towards the room inside, not even caring about hitting the wooden table along the way.

"Look, is this Duke, uh, Duke." Miss Shirley, who was unkempt in the inner room, was uncovering a pottery jar on the wooden table with excitement. When she raised her head, she happened to see Aruod appearing here. She couldn't help but be surprised. She was too focused on the experiment.

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

"Is this?" Leila asked curiously.

"Yes, this is penicillin, also called penicillin, it's done." Arud slapped his thighs excitedly. He could not cure the joy in his heart. This thing is even more precious than gold. You must know that almost all diseases in this era can be cured, and tetanus, which has the highest mortality rate in war, can be treated.

"It's great, I finally didn't waste my energy." Miss Shirley wiped the sweat with the back of her hand, and a happy smile appeared on her face.

"Okay, the next step is to extract penicillin. I asked the smelting base people to make this." Arud took out a small round copper bucket like a magic trick, and then pulled it out, and it turned out to be a dropper. Of course, one of the modern rubber is made of the milk/head of the cow. Fortunately, there are leather makers in the smelting base.

With the efforts of Miss Shirley and Leila, the first penicillin of this era was made. Although Arod didn't know if this was right or not, he finally felt that in the face of the most terrible disease of this era, he no longer looked like a warrior without weapons on the battlefield. On the battlefield, his weapons were an excellent sword. On this invisible battlefield, penicillin would be his weapon and wealth. (To be continued.)
