Li Chengfeng said: "First of all, immediately make a large number of anti-evil suits!"

Zhao Hanqing said: "What is an anti-evil suit?"

Li Chengfeng said: "These plagues are caused by evil spirits entering the body, and these evil spirits can be prevented!"

Zhao Hanqing perked up and said, "Oh, can these evils be prevented?"

The statement that there are no bacteria in Daqi is too troublesome to explain, so Li Chengfeng used the general expression of evil.

Zhao Hanqing was most worried that there was no way to prevent and control such a violent plague, but as soon as he heard what Li Chengfeng said, he was immediately overjoyed.

Li Chengfeng said: "That's right, you can prevent it! This evil is often spread through three ways, saliva, breath, and skin, so we only need to prevent it in these three ways." ”

Zhao Hanqing listened carefully, and took out his own style of being a student in Taifu Academy, respectfully.

Li Chengfeng said: "Your Highness, it is not enough to use a masked face towel, you must thicken the isolation! At the same time, you must use an object that can absorb evil spirits to separate it!"

Zhao Feiyue couldn't help but ask, "Absorb evil objects?"

Li Chengfeng nodded and said, "That's right! Evil spirits are small evil bodies that are difficult to see with the naked eye, and they will spread in the air through human saliva and body fluids, and enter the eyes, ears, mouth, nose, and even skin of the human body. If a person wears thicker clothes, he can take relative precautions, but the first thing to focus on at this time is the breathing of the person!"

A top-level cultivator like Zhao Feiyue didn't care much about this, because she had her own position, and when her aura was fully open, even people couldn't enter within a few meters of her surroundings, and it was even more impossible for these small evil cults to enter.

But for ordinary mortals like Zhao Hanqing, it would be panicked in their hearts, because who is not afraid of diseases that can be transmitted by breathing?

Zhao Hanqing frowned and said, "Is there any effective medicine?"

Li Chengfeng smiled and said, "Yes!"

Zhao Hanqing immediately asked, "Is it expensive?"

Zhao Hanqing's words point out the key to the problem, if this thing is very expensive, it will become a luxury for the powerful to save their lives, and the people will still die in pieces, which is not Zhao Hanqing's wish.

In Zhao Hanqing's eyes, most of those big families and powerful people are the world's first-class hateful existences, they are rich and rival the country, but they hoard and live in strange places, almost do not pay taxes, but they are desperately knocking on the bones and sucking the marrow.

If possible, he is even willing to clean up the big households of the atmosphere, so that he can clean up these garbage and dregs that do not pay taxes, and enrich the treasury.

It's a pity that his position determines that he can't do this, not only can't, but he also has to unite these big families, otherwise...... Even if he is the crown prince, he can't sit in a stable position and can't do things.

Li Chengfeng smiled and said, "It's not expensive, it's very cheap, and it's available everywhere." ”

Zhao Hanqing and Zhao Feiyue's eyes widened in disbelief, and they lost their voices: "What is it?"

Li Chengfeng broke off a small piece of wood from the carriage and said to Zhao Feiyue, "Ignite." ”

Zhao Feiyue looked puzzled, but he still did it, casually pointed at it, and the wooden strip ignited by itself, Li Chengfeng held it, and after a while, when the wooden strip was almost burned, he extinguished it, and then rubbed the charcoal strip burned into charcoal on the floor of the carriage a few times, scraping out a thin layer of black ash, and then he picked up the black ash, rubbed it with his hand, raised the black sticky fingers, and said to the prince: "This is it!"

Zhao Hanqing was stunned: "Charcoal?"

Li Chengfeng nodded and said, "Yes or not! More precisely, charcoal powder!"

Zhao Hanqing said curiously: "Charcoal powder can absorb evil spirits?"

Li Chengfeng said: "Yes, although the effect is not the best, it is already the best choice at this juncture." ”

Zhao Hanqing said: "How to use this charcoal powder?"

Li Chengfeng said: "Wrap it in casing, drill many small holes in the middle, and then wrap it in eight layers of gauze before and after, so as to prevent evil spirits from being inhaled into the body." ”

Zhao Hanqing asked, "What kind of item is the better effect?"

This better item is naturally the famous activated carbon, but Li Chengfeng knows that activated carbon is to be made through industry, which involves physical reactions and chemical reactions, not to mention that he doesn't know how to do it, even if he knows that he can't do it here for a while.

Therefore, charcoal, which does not work so well, is the only choice.

Li Chengfeng shook his head and said, "I won't make such items, and I can't make them at this time." Your Highness, don't be too ambitious!"

Zhao Hanqing didn't have the slightest pretension of the prince of the country, he nodded hurriedly, and said, "Yes, if this method works, the merit of the virtuous brother of the wind is immeasurable!"

Li Chengfeng said: "This alone is not enough! We also need to prepare anti-evil clothing! His Royal Highness will immediately collect a large number of casings in the city, sew them into clothes and gloves, and vigorously wrap the bare skin. ”

Zhao Feiyue said worriedly: "But, where can I get so many large number of casings in this hurry?"

Li Chengfeng said: "These are only for doctors and apprentices who help with patients, as well as nursing. Ordinary people are mainly screened first, and then those with symptomatic reactions are isolated. ”

Zhao Hanqing was in a good mood, he quickly wrote it down, and said, "Is there anything else?"

Li Chengfeng said: "Yes! That is, disinfection and hygiene! Everyone must drink water that has been boiled for a quarter of an hour, and absolutely must not drink raw water! At the same time, all well water in the city must no longer be used, and water must be taken from the living water outside the city! At the same time, all the dirty places in the streets are covered with lime, and all people must defecate and dispose of them in a centralized manner, and they must not excrete and dump their urine and urine anywhere, and they must be arranged in a unified manner. ”

Zhao Hanqing was stunned when he heard this, and Zhao Feiyue's cheeks were flushed, and she wanted to speak again.

Zhao Hanqing was puzzled: "How to arrange this defecation in a unified manner, I'm afraid it will be inconvenient." ”

As soon as Li Chengfeng heard this, he knew that Zhao Hanqing had a mistake, and he said: "I mean, dig deep into the manure tank, dump all urine and urine in a unified manner, and it is not allowed to defecate anywhere, let alone dump feces at will, and violators will be severely punished! Evil spirits are often spread by filth, and this must be strictly controlled!"

Zhao Hanqing slapped his face and said, "This is easy to do!"

Zhao Feiyue also breathed a sigh of relief, she thought that Li Chengfeng wanted her to urinate with the others, then she would die of embarrassment.

Li Chengfeng continued: "At the same time, recruit people in the city who understand medical skills and nursing, regardless of men and women, and immediately equip them to prevent evil after screening if they have no symptoms, and let them be put into the front line to fight!"

Hearing Li Chengfeng's words, Zhao Hanqing's expression was awe-inspiring, he knew that this was a battle without gunpowder, but the process and result of the battle were far more dangerous and cruel than those on the battlefield!

Because their enemies are the invisible plague!

After Li Chengfeng explained the specific precautions in detail, he said to the prince: "This prevention will be handed over to His Royal Highness, and I will discuss with Her Royal Highness the princess how to treat this plague!"

The prince nodded and said, "Okay, without further ado, I will immediately order someone to do it!"

The prince quickly got out of the carriage, quickly called someone, and gave Li Chengfeng a few instructions that he had summarized, and immediately the officials, gentry, and big families in Taiyang City immediately mobilized.

At the same time, the crown prince ordered all the troops in the city to immediately conduct self-screening, and the soldiers without symptoms immediately went out of the city to besiege the city of Taiyang, and no one was allowed to leave the city or enter the city.

These officials and big families are the most well-informed, and soon they fell into a panic, and they immediately wanted to flee from here if they had the money and conditions, but they soon found that the entire Taiyang City was besieged, and no one could get out, no one could enter!

Under the threat of death and illness, they had to unite and start desperately trying to save themselves according to the methods provided by the prince!

At this time, Li Chengfeng looked at Zhao Feiyue and said, "Prevention alone is not enough, we have to find a way to treat it, otherwise...... Those who are sick are afraid that none of them will survive......" He was saying when suddenly his eyes kept and he lost his voice: "Oh, damn it!!"

Li Chengfeng immediately jumped out of the carriage and rushed in one direction, Zhao Feiyue was startled, and hurriedly chased after him, "What's wrong?"

Li Chengfeng ran wildly and shouted: "Little bamboo!!Little bamboo, you must not have anything to do!!"

There is another sentence that he silently shouted in his heart: Yuehan, you can't have anything to do!!
