Quick travel: I am bound by the longevity system

"Mr. Li, Mr. Zhu, Mr. Zhou." The students also looked excited when they saw these people.

Mr. Li and the others walked into the classroom.

"This painting is pretty good. You can tell it looks like everyone's at first sight." Mr. Li said with a smile, "You must have been practicing for a long time!"

"When I was young, I followed my father in drawing pictures of herbal medicine. Fortunately, my basic skills were good and I didn't embarrass my ancestors." Lin Jiu said with a smile.

""The Barefoot Doctor's Handbook."" Mr. Li picked up the book on the desk and flipped through it, casually talking to Mr. Zhou and the others. "This book is well compiled. It is not only practical on the battlefield, but also good for treating common diseases. Reading this book is like having a family doctor at home!"

Mr. Zhou also read the contents of the book carefully, "The contents are indeed practical. With this book, we can train a large number of medical staff. In this way, I will ask our printing house to first print this "Barefoot Doctor's Manual" together with Xiao Lin's Comrade's notes will be printed, but the royalties still have to be paid to Comrade Xiaolin."

"Mr. Zhou, I am not the original author of this book, and I deserve the royalties. I published this book in the hope that more people will learn the knowledge in the book and benefit more ordinary people, so I will receive the royalties. I won't charge it." Lin Jiu naturally agreed to publish a large number of "The Barefoot Doctor's Manual", but the royalties could not be charged under any circumstances.

"Even if you don't own "The Barefoot Doctor's Manual," these notes are still your accumulation over the years, and you always deserve the copyright fee." Mr. Zhou said with a smile.

"I plan to donate the notes to the Medical University for free. As for the future copyright fees, they will also be used to build the Medical University. I hope the Medical University can train more medical staff for our country."

"We admire you for your righteousness, sir."

"No, you are the people I admire the most."

Lin Jiu's current achievements are only because she lived a few more lives and had the help of the system. Without the system, she would be just an ordinary person. And these older generation talents are really admirable. Compared with their contributions to this country, what Lin Jiu has done is far from enough.

"Mr. Li, Mr. Zhu, Mr. Zhou, it's lunch time. Let's go to the cafeteria to eat first." Dean Yang walked into the classroom with a smile.

"Then let's have a big meal in the school cafeteria today." Mr. Li and the others walked out of the classroom with a smile, while Lin Jiu was slower than them.

There are no vegetables in the canteen in winter, except for potatoes, cabbage, and pickled beans. The rice is multi-grain rice and steamed buns.

Looking at the food in the canteen, everyone said nothing, just took the bowls and took lunch one after another. Lin Jiu bought some cabbage and sour beans, ordered two more steamed buns, and found a table in the cafeteria to sit down. At this time, Mr. Zhu and the others also sat down.

Lin Jiu took small mouthfuls of the steamed buns, feeling strenuous every time he ate them. Fortunately, he had pickled beans to eat with them, so Lin Jiu was able to swallow the steamed buns.

"You can't bite this Wo Wotou without a pair of good teeth." Mr. Li picked up a Wo Wo Tou and took a bite. "It seems that my teeth, Old Li, are pretty good."

"When life gets better in the future, I will definitely make this steamed bun softer than steamed buns. Even a toothless old lady can grind it." Lin Jiu broke off a piece of steamed bun and put it in his mouth slowly. Chewing.

"We'll be waiting to eat the soft steamed buns you made then." Lao Li said with a smile.

After lunch, Lin Jiu talked about the contents of the "Barefoot Doctor's Handbook" with Mr. Li and others. They talked from medical treatment to education, and from education to economy and military.

When talking about the military, it is indispensable to talk about weapons.

"Xiao Lin, the explosives you used to blow up the county town and the Japs seemed more powerful than the explosives used by the Japs and us?" Liu Mingzhao had long wanted to ask Lin Jiu about weapons.

"Well, that is a high explosive, more powerful than ordinary explosives." Lin Jiu thought for a while, then took out a pen and paper to write down the formula for this high explosive. At the same time, he gave several recipes for making gunpowder. Finally, I did not forget to tell everyone that some things in nature can also cause explosions.

Lin Jiu thought for a while and drew the pattern of the three-edged sword.

"This kind of bayonet has blood grooves on three sides. Once it pierces the body, it will not bleed within a few seconds. But as long as the bayonet is pulled out, the bleeding will stop. Moreover, this wound is extremely difficult to suture. Even if it is me, I will not bleed for a few seconds when I am short of medicine." Under such circumstances, it is difficult to rescue people." Lin Jiu showed her Mitsubishi Spike to several people. Why did she dare to break into the Japanese turret alone? That is, in addition to her own powerful kung fu, she has more means of killing.

"It is indeed a sharp weapon." Mr. Zhu picked up the spike and looked at it carefully, then returned it to Lin Jiu.

He has led soldiers and fought in battles, so he naturally knows the role of a good weapon on the battlefield.

"If the little devils don't like fighting with bayonets, then these spikes are a great gift from us."

Mr. Zhu and the others had other things to do, so naturally they couldn't stay in school all the time. Before they left, they took away Lin Jiu's manuscript and several weapons drawings.

After Mr. Zhu and the others left, Lin Jiu worked with the students to make blood residual carbon.

"The hair used to make blood residue carbon must be washed clean. This is because there are still some oils and impurities in the hair. After cleaning the hair, use a dry towel to dry the water on the hair. You can also dry it if you are not in a hurry." Lin Jiu was washing the students' cut hair while talking about precautions.

The hair was all freshly cut by female students. When these female students heard that Lin Jiu was going to teach everyone how to make blood residual carbon, they all cut off their long hair.

Set up a big pot in the school courtyard and put the washed and dried hair in it.

Cover the pot with an iron pot lid, and then seal the pot tightly with mud, leaving no gaps.

After doing this, put a piece of white paper on the lid of the pot and light the fire under the pot.

"When calcining blood residual carbon, you must use martial fire, and the reason for putting paper on this pot is to observe the degree of calcining of blood residual carbon. When the paper on the lid of the pot begins to carbonize, the blood residual carbon is ready. .At this point we need to anneal and wait for the pot to cool completely."

In order to prevent the paper from being blown away by the wind, Lin Jiu pressed a small tile on the paper.

Just watch the fire during the calcining process. Everyone took advantage of this free time to ask Lin Jiu other questions, and Lin Jiu answered them one by one.

"Teacher, you said before that residual blood carbon can cure maternal hemorrhage, but what should we do if there is no residual blood carbon at that time?"

"If you encounter this situation in the future, you can quickly cut off the mother's hair and burn it to ashes, and then drink it with rice wine or warm boiled water. This can also quickly stop bleeding. In fact, giving the mother the blood carbon made from her own hair will have the best effect It’s the best.”

At night, the paper on the pot lid turned brown. At this time, Lin Jiu stopped the fire. When the pot gradually cooled down, Lin Jiu opened the pot lid.

"This is what the freshly made blood charcoal looks like."
