Or use irritating animal drugs, centipedes, dung beetles, eel fat, chicken blood, squid bones, etc. For example, in the "Medical Sect Jinjian", "take eel fat and apply it three times a day." ”

As for acupuncture, it is Yu Xi's specialty.

"Preparation for Emergency" records that you can use the method of "moxibustion on the knuckles of the left and right hands to extend the three strong in Wanzhong" to treat ulcers and "vitiligo". Yu Xi also tried.

Yu Xi told Chen and Liu Jin about his idea, and they also felt that it was feasible.

It's just that the cycle of curing vitiligo is too long, and the time is not enough.

"You only give him a doctor's hand, and if there is an effect on his hand, then put forward the conditions." Liu Jindao. He believed in Yu Xi's medical skills, after all, the news that she operated on Lan Wangwu had already spread among the people.

So the three of them discussed some countermeasures and went to the farm.

The owner of the vitiligo farm, surnamed Gao, was a little surprised to see them come back so soon, and he thought they would have to think about it for at least a few days.

Looking at Yu Xi's dress, he said that he was really a few customers who were not bad for money, and he probably didn't know what the normal selling price of the sheep bladder was.

Who knew that Yu Xi's first sentence when he saw him was: "Boss Gao, let's not mention it in advance when we buy bladders, I can cure you for white epilepsy." ”

The cow-like high boss, this vitiligo was there when he was young, he sought countless medical advice since he was a child, and he was deceived many times on the way.

"You guys get out!" He pointed in the direction of the gate and shouted with a blushing face.

Seeing that the three of them were not moving, they actually picked up a stick more than three feet long and waved it at Yu Xi.

"Boldly Diao Min, against you!" Chen He's eyes were quick, and he shouted loudly and grabbed the stick, and restrained Boss Gao with three punches and two kicks, trampling him under his feet.

Boss Gao saw that Chen He was extraordinary, and he was also a little weak.

"What the hell are you going to do? If that's the case, I'll report it to the police. ”

He lay on the ground and lacked confidence, but he refused to suffer on his lips.

Yu Xi stretched out his hand to untie a piece of jade pendant from his waist, squatted in front of Boss Gao's eyes and shook it to show him.

The jade pendant is carved with a delicate dragon and phoenix peacock, forming the word "forget worries", which is the token that Lan forgot to worry about.

"The three of us are the female officials and guards of the princess of Lancang Kingdom, and the purchase of this batch of sheep bladders is a human-to-human disease in the palace, and we need to use it for medicine. There is money, but we know the market price of the sheep's bladder, and it costs a thousand taels of silver, and those who know say that your lion opens his mouth, and those who don't know think that we swallowed it privately. ”

Lancang and Tanran are not neighbors, and the two countries have no contacts. Naturally, the relationship between Feng Guo and Tanran is not as tense.

This statement was discussed by Yu Xi and the three of them, and when buying things in the name of the royal family, Boss Gao did not dare to go too far.

"You...... So what do you want? "Boss Gao will be suspicious, but he has already lost in momentum.

Yu Xi's rich and cold temperament is innate, and she said that she is from the palace, which is very convincing. Moreover, there is no agriculture and animal husbandry in Lancang, and the animal husbandry industry in Fengguo is not developed, so there is a good reason to come and buy sheep bladders.

"It's very simple, I'll treat you today, and if there is an improvement within three days, you can sell me a thousand sheep bladders at the normal market price, and I'll continue to help you treat you until the leudomy disappears."

"If you sell me a thousand sheep bladders, and I don't heal you, I will compensate you 1,000 taels of silver. No matter how you calculate, you will make a profit without losing money, how about it? ”

Yu Xikai's conditions were fair and reasonable, and he did not deliberately ask him to sell at a low price.

Boss Gao hesitated for a moment and asked, "How can I trust you?" ”

Yu Xi curled the corners of her lips: "Regarding the treatment, I will issue a signed contract for you." Besides, I am the one who forgets the princess, and I have the guarantee of royal credibility, and I will not be untrustworthy. ”

Chen He stepped on Boss Gao's fat back with one foot, stood on the ground with one foot, exchanged glances with Liu Jin, and couldn't help but be amazed by Yu Xi's negotiation ability.

The three days passed quickly, and in the end, Yu Xi relied on the vitiligo special ointment he had prepared for the slaughterhouse owner in exchange for a thousand sheep bladders.

Boss Gao showed his first appearance in his life at this time.

Although his vitiligo could not be cured in three days, it was much better, and the color was not as distinct as it was at the beginning.

The high boss who turned from a cow to a scalper saw Yu Xi and thanked him, more than 1,000 sheep bladders, and he didn't ask for a penny.

Yu Xi didn't let him lose, and gave him a lot of drugs for follow-up treatment.

After going back, Gong Chengyun in the barracks listened to Chen and Liu Jin's description of what happened, and looked at his sister even more differently. Overnight, according to Yu Xi's idea, a thousand "hand **" were made out.

I tried to explode a few, and the power was excellent. Gong Chengyun was even more overjoyed.

"I knew that I had such a sister, and it was not a matter of searching for things to take it, so why did this battle take so long."

Gong Chengyun looked at Yu Xi with emotion.

Yu Xi knew in her heart that her little intelligence was nothing, she just summed up the crystallization of human wisdom for thousands of years.

Sometimes she can't help but wonder, a little bit of human progress, those leaders, pioneers, inventors, is it possible that they are all time-travelers like her?

She hides so deeply, and no one knows the secrets of her crossing. Is there anyone like her in this era? Just don't know each other?

Having a secret that only you know in the world is the loneliest thing. Yu Xi smiled bitterly in his heart.

But he said to his brother: "Don't worry, have I made the earthen cannon launcher I made?" ”

Gong Chengyun clapped his hands, and a few people pushed a big wooden guy.

Yu Xi released a few self-made ** balls to shoot out, and the range was also according to Yu Xi's expectations, which could hit the enemy directly.

Very good, although there were some hiccups along the way, overall the first two were well done.

The last item is not a problem for Yu Xi, the biggest problem is the gas mask for the soldiers of Fengguo, and it takes a lot of time to select materials and make them.

Yu Xi thought about it again and again, and finally decided to use three layers of non-woven fabric plus bamboo tube and activated carbon to make a modern "pig nose". In the style of a mask, he made an elastic cord and tied it to his ears.

Compared to the gas masks of the 21st century, they are simply crude and rudimentary. Not to mention the protective effect, if you really wear it to fight a battle, whether it will suffocate is a question worth considering.

After repeated experiments, Yu Xi and Gong Chengyun discussed using poison gas as a reserved weapon, and not using it unless absolutely necessary, so as not to injure the enemy by one thousand and lose eight hundred.

"I miss the era of automation so much!" Yu Xi complained bitterly in his heart, and said that if it is in the era of full automation and mechanization, why is it so!
