Both worlds are like dreams

Lu Wenxuan nodded. "I have already submitted a memorial to Shangyang City reporting the situation in the city, requesting His Majesty to send the best doctor to treat us. The time should have come. But it will probably take at least half a month for him to come back."

"But the medicinal materials in the city can't last that long." Hua Yu said.

Xue Huang pinched the gemstone and suddenly looked a little surprised. She tried to speak naturally, "Aunt, are there any wine and vinegar shops in the city?"

"There are six wine shops and four vinegar shops in the city," Hua Yu asked in confusion, "Why are you asking this suddenly?"

Xue Huang felt a little guilty and said, "General, please tell the people in the city that every household should prepare a pot, pour vinegar into it and boil it, and use the steam to fumigate the house every day, or sprinkle it in the house."

"What is this for?" Hua Yu was increasingly confused about what she was talking about.

Xue Huang: I’m just relaying it!

"Aunt, believe me, the plague is actually caused by a virus, and vinegar can be used to disinfect it after heating. Although it cannot cure them, it can prevent them from contracting the plague."

Although Lu Wenxuan had never heard of this method, he still did as she said. "Don't worry, Princess. I will definitely execute it."

Xue Huang nodded, "But this solution is only temporary. I hope the general can help me find a clean place. I also need a lot of strong liquor, ice cubes, a lot of cans, and dozens of cauldrons."

"What is this for?" Lu Wenxuan asked.

"This is the secret method that the miracle doctor taught me. Please help me, General."

Lu Wenxuan nodded, "Princess, don't worry. What you need can be arranged right away. The place can be chosen in the general's mansion, and I can come whenever you call."

"Thank you, General." Xue Huang said.

Lu Wenxuan looked at Hua Yu again, and just as he was about to speak, Hua Yu said, "I'll stay and help her."

"But……"

"I am also from Muhua City, so I naturally have to do my part. Besides, she is not only my niece, but also the princess of Beiling. Her safety is very important. You will need to go all out to save the people in the city, so leave this matter to me."

Hua Yu's words were quite thoughtful, and Lu Wenxuan naturally couldn't find a reason to refuse, so he had to say: "Then you...you and the princess must be careful. I will ask someone to clean up the room."

Lu Wenxuan bowed and left. Hua Yu seemed to have something else to say, so she followed him out.

Seeing them walking away, Xue Huang hurriedly said, "Hey, what you just told me, about vinegar and wine, can it really save people?"

"It's disinfection!" the boy said. "The plague is indeed a virus, produced by bacteria, and vinegar and alcohol can kill certain bacteria to some extent."

"I don't understand," Xue Huang raised an eyebrow and said, "What is alcohol? Is the wine a spirit? And what are bacteria?"

"It will be very troublesome to explain. I will tell you in detail when I have the chance." said the boy.

"Are these all things from the world you mentioned? Are they really useful?"

"It can play a big role, but this plague is so fierce that many people will still die. You have to be prepared for this."

Xue Huang sighed, "How can there be a plague that doesn't kill people?"

"So all we can do is try our best to protect those who are still alive," the boy comforted.

"Yes!" Xue Huang said. "I'm protecting the people here, which is also considered as guarding the border of Beiling. They should be more relaxed in Shangyang City, right?"

"It's been three years, and you still can't forget it at all." The boy sighed.

"I promised him that I would go to Qinghai Lake, and I can't break my promise. If I can successfully resolve the issues here, I will borrow some money from my aunt and buy an island near Qinghai Lake. I want to have a beautiful manor on it, and I can see the beautiful scenery when I open the window."

The young man was silent for a moment, then said, "In fact, sometimes fate is not immutable."

"what are you saying?"

"Nothing," the boy said, "Let's deal with the current situation."

Lu Wenxuan prepared everything Xue Huang needed in just one day, and gave her a secluded and spacious courtyard in the backyard of the general's mansion for her use.

Xue Huang looked at the wine jars all over the yard and could even smell the strong aroma of wine. She asked, "Tell me. How do you make wine become a spirit?"

The young man rolled his eyes, his face full of helplessness, but Xue Huang couldn't see it, so he could only try to be calm and said: "You don't need to ask so many questions, just do what I say."

Xuehuang nodded and went outside to call in Hua Yu and the people sent to her by Lu Wenxuan.

Now the whole city was filled with the smell of vinegar, which made her dizzy. However, she still managed to hold it in and said, "Thank you all, set up the pot according to this diagram."

This picture shows the materials and methods used to extract alcohol that the boy taught her, but Xuehuang was not a good painter, so she asked Huayu to draw it.

The content of the picture is also very simple. It is to put a basin that is smaller than the big pot on it, and then put a wooden board across two feet above it, and put ice cubes on it.

Although everyone was puzzled, they still did as Lu Wenxuan ordered.

After learning the process, the soldiers immediately made clear division of labor, everything was in order, and they acted quickly.

Xue Huang couldn't help but admire Lu Wenxuan's leadership and execution abilities. This group of people prepared everything she wanted in just one hour.

Xue Huang led everyone to pour hundreds of jars of wine into the pot, and then started to light the fire to heat it.

"Everyone, please be careful. Alcohol is flammable. We must not burn down the general's mansion." Just as Xue Huang finished speaking, the firewood next to her caught fire.

It turned out that a soldier accidentally spilled the wine on the ground when pouring it, and when he lit the fire, sparks flew out and ignited it directly.

Behind the firewood was the unused liquor. If the fire spread there, the whole yard would probably be ruined.

"Quickly fetch some water..." Before the soldier could finish his words, he saw a white breath spreading over like a spirit snake, and the fire was suppressed instantly. He looked closely and found that the white breath was actually frost.

The extremely cold temperature put out the fire in an instant, and the soldiers quickly wiped the wine off the ground.

Lu Wenxuan also rushed over and happened to see this scene, “Princess, are you okay?”

Xue Huang shook her head, "Fortunately, the general's mansion was not burned down."

"Princess, you're joking. It's just a mansion. It's not important. As long as no one gets hurt, it's fine." Lu Wenxuan looked at the big pot of liquor next to him, "What is it used for?"

"High-concentration liquor can be used to remove poison."

"When we were injured on the battlefield before, we had no medicine, so we would spray wine on the knife and then cut the wound to remove the rotten flesh." Lu Wenxuan said.

Xue Huang nodded, "That's right. Alcohol can prevent wounds from getting infected, and the stronger the alcohol, the better the effect. However, these alcohols are not strong enough. Heating them at high temperatures may increase the concentration."

Lu Wenxuan watched the wine in the pot gradually boil, and the heat continued to rise, but because there was a wooden board across it, the heat was blocked by the ice and condensed into water drops that fell into the basin above the pot. In fact, this project was not complicated, but he had never heard of such a clever method before.
