Yang Yun summoned everyone in Camp No. 2 and forcibly gave the order.

He wanted everyone to know that violating the indigenous people would be punished as badly as hurting the people of the Tang Dynasty, and although these people were prisoners of war for the time being, they would also become part of the camp in the future.

Most of the people in Camp 2 were ordinary people, they were afraid that Yang Yun would abandon them here forever, and they had seen Yang Yun's almost divine skills, so they could only do what they were told.

Yang Yun felt a little tired, and he hadn't rested well these days, so he came to Camp No. 1, preparing to return to Datang after inspecting a lap and get a good night's sleep.

As a result, when I arrived at Camp No. 1, I learned that there was a big trouble here, and last night a giant python attacked the camp, injuring two craftsmen, one of whom was seriously injured and even dying.

Although the python was finally driven away, the craftsmen were obviously timid, and their rebellious mood was high, and they all had the intention of continuing to work and leaving.

"It has been diagnosed, but it is still life-threatening."

Uncle He walked over, his face full of worry, and said, "In the middle of the night, we couldn't contact the owner, so we took the wound medicine we prepared before to stop the bleeding, and now I'm afraid that the wound will continue to worsen." ”

Yang Yun sensed an unprecedented crisis.

These people in Camp No. 1 are basically recruited from Luoyang City, and they have a skill, and they are sent here in the name of alchemy, and he is more lenient with these people than the people in Camp No. 2, after all, they have promised that they can go back to reunite with their families from time to time, but now that such a thing has happened, if they are brought back to Luoyang's doctor for diagnosis and treatment, how can they justify themselves?

Yang Yun said: "I will find the best medicine for them, and it is better to stay here for a while to recuperate than to return to Datang...... It's already the height of summer, and the wound is easy to rot and suppurate, and I'm afraid that if I go back, I won't be able to support it anymore. ”

Yang Yun can't take the wounded and sick back to Datang for the time being, but has to treat them in the Americas, in addition to preventing them from being discovered by outsiders, but also considering that their injuries are easier to save in the climate of South America.

Yang Yun immediately returned to Datang with a group of girls.

Because it is already early in the morning, Luoyang has already curfew, and it will take two hours before dawn, it is not easy to raise the necessary medicines, and ordinary wound medicine cannot treat the two, and anti-inflammatory drugs such as antibiotics must be found, which is almost impossible in this era.

Fortunately, Yang Yun had studied something similar before, and in his laboratory, there were already some raw materials for making improvised antibiotics, that is, Houttuynia cordata.

"Master, are we going to find Miss Mi and ask her to provide us with medicinal herbs?"

Wu Yuan saw that Yang Yun was in a hurry to go home, and then went out as soon as possible and took them to the laboratory in the same place, so he asked curiously.

Yang Yun said: "Time is urgent, I won't say anything superfluous, now you have to listen to me in everything and act according to my orders." Yidan, you go and boil water, Yarou, you go and call Jingyan and An Lun to come over...... Wu Yuan, you help me bring the alcohol I prepared before. ”

What Yang Yun has to do is to make Houttuynia cordata injection.

Houttuynia cordata is something that can be bought in ordinary Chinese herbal medicine stores, and alcohol has been researched by him since he came to Datang, and he still needs some other materials now, if it is replaced by him when he first came to Datang, it is absolutely impossible, but now it can basically be made.

That is sulfuric acid and caustic soda.

These two things were made up by him in the laboratory before.

The manufacture of sulfuric acid is very simple, he ordered ceramic cylinders and ceramic tubes of different sizes, composed a group of two large vats, one up and one down, and then used a thick clay ceramic conduit at the mouth of the bowl to connect the docked large vats, and glued them with binders to form a closed space, so that it became a distillation tower composed of five groups of large vats.

Using the principle of producing sulfuric acid and nitric acid by the lead chamber method, the gas containing sulfur dioxide is prepared after roasting including pyrite, sulfur, smelting flue gas, hydrogen sulfide, gypsum and waste sulfuric acid, and after complex chemical reactions, sulfuric acid liquid is formed to drip out to obtain sulfuric acid.

As for caustic soda, it is simpler, put water in an iron pot, heat the water to heat up, slowly add salt, stir fully, add hydrated lime when it becomes a thick liquid, stir it sufficiently, precipitate after full reaction, filter, dialyse the sodium carbonate out, and wash it once with a small amount of water.

Then pour the filtrate into the iron pot to boil and concentrate, and then stop the fire, then the calcium carbonate and other sundries that sink to the bottom of the pot are washed with water twice, and the washed sodium hydroxide liquid is poured into the iron pot to continue to evaporate and concentrate. The liquid sodium hydroxide is heated and concentrated, and poured into the iron drum in time, and it is caustic soda after cooling.

Everything was ready, Yarou called all the girls through the space door, even the youngest Yaqing came with her, obviously this little girl also wanted to help Yang Yun.

"You are responsible for distilling water first, there must be no impurities, the distillation does not need to be too fast, you can evaporate a liter of water before dawn."

Yang Yun arranged for Yaqing and Yarou to help Yidan boil water, they had already been familiar with steaming wine before, and it was not difficult to distill some pure water.

Wu Yuan brought Yang Yun's jars, Yang Yun asked Zhang Jingyan to grind the powder of Houttuynia cordata, and after grinding, he cooperated with An Lun to add alcohol to it, reheat, shake the jars, and extract Houttuyn cordata, and then add a small amount of sulfuric acid and caustic soda to filter the houttuyn in the alcohol.

While Zhang Jingyan was working, Yang Yun was concentrating on the laboratory next door, researching and manufacturing "chloroform", which requires some methane and chlorine, which can only be completed by changing the properties of the substance by the experimental assistant Wu Yuan, in fact, it is separated by salt water.

Chlorine is mixed with methane, and through the heating reaction, chloroform is formed, which is added to the jar, and the caustic soda undergoes a chemical reaction to produce precipitated impurities, which are then filtered with gauze, and the rest is the distillate of alcohol, houttuynin and a little sulfuric acid.

Through two distillations, the alcohol is first evaporated by low-temperature distillation, and then through secondary distillation, the houttuyn and water that Yang Yun needs are evaporated and filtered into a new container.

This gives Houttuynia cordata concentrate.

Combined with distilled water and salt, the normal saline mixed with Houttuynia cordata concentrate forms a biological anti-inflammatory drug that can be injected into the human body in this era.

……

……

Yang Yun took the Houttuynia cordata concentrate he made, the needles made by special methods, etc., and hurried to South America to give the injured two people an infusion.

Intravenous injection, for Yang Yun, the technology is not complicated, but the needle is a little big, the needle created in this era is a little thick, plus the need to fill the real thing in the middle when building, and remove the hollow needle tube after the build, which will affect the sharpness of the needle.

However, the needles were quite qualified, and after some hard work, the anti-inflammatory drugs were finally injected into the two of them.

The situation seems to be good, especially with the saline infusion, even if it is less effective than the blood transfusion, their condition has basically stabilized.

"Boss, what did you put in for them?" On behalf of the craftsmen in the camp, Uncle He came to inquire about the busy Yang Yun.

Yang Yun didn't know how to explain, just shook his head lightly, and said, "In short, it is something that can save lives, and it belongs to the immortal family's means...... However, whether they can survive depends on creation, as long as they can survive these two days, there will be no big problem. ”

Uncle He was incredulous: "The owner is not ready to take them back?" ”

Yang Yun asked rhetorically: "Do you think that with their current condition, they can withstand the bumps of the journey?" ”

All of a sudden, Uncle He and a few craftsmen next to him had nothing to say, indeed in the current situation, it is best not to toss the injured, they don't know how Yang Yun completed the back and forth from Datang, if they knew that Yang Yun could return to Datang in an instant, they would definitely let Yang Yun bring people back.

But Yang Yun knew that even if he brought the injured two back, it would be useless, it was better to stay here in South America, at least the weather here would be colder than Datang, which would have a certain effect on the recovery of the injury.

The people in the camp are in a very poor mental state, probably because of the attack of the giant python last night, and they are a little frightened.

Immediately, Yang Yun arranged for manpower to strengthen the city wall.

After the lesson of blood, the craftsmen took the initiative in building the wall, not only greatly increasing the height, but also sprinkling quicklime and sulfur mined from nearby around the perimeter, which greatly increased the safety of the camp.

……

……

When Yang Yun returned to the residence in Luoyang, the whole person was exhausted.

In one night, through war and rescue, he also accomplished a seemingly unlikely feat of refining biological antibiotics.

Right now, he just wanted to sleep, but just as he was about to rest, an uninvited guest came to visit, and Yang Yun was very surprised, Princess Xianyi, who should have disappeared, but appeared in front of him.

After designing to kill Concubine Wu Hui and parting ways with Princess Xianyi, Yang Yun thought that he would never see the little princess again.

But after all, the two can be regarded as relatives now, Princess Xianyi didn't know the truth about her mother's death, so she didn't shy away from meeting Yang Yun, and even took the initiative to come to the door, as if she had something important to ask.

"Was it a surprise?"

Yang Yun met Princess Xianyi at the door of the residence, and the little princess saw Yang Yun's stunned expression, and immediately asked in an unkind tone.

"How is it possible, the princess is here, it is an honor!"

Although Yang Yun was surprised, he didn't say so.

I secretly wondered in my heart, with the arrogance of Princess Xianyi, would she put down her body and take the initiative to make peace with him? Unless Princess Xianyi is in some big trouble, or wants to use him for something.

"Inside, please."

Yang Yun invited Princess Xianyi to the courtyard.

The yard was clean, just much smaller than his previous residence, and the whole courtyard seemed cramped.

Princess Xianyi looked around, frowned, and asked quite incomprehensibly: "I have no home to return to, living in such a shabby and dilapidated place, just want to avoid the two wives in the family?" Why bother a man to do what you do? ”

Yang Yun wanted to laugh in his heart, what does it matter to you if I am bitter?

You'd better take care of yourself first!

Yang Yun's expression was indifferent: "In the lower body in the Daomen, pay attention to pure heart and few desires, for the time being, I don't want to be contaminated with red dust, it is better to hide outside, I have been busy alchemy for Your Majesty recently, and I really have no time to take care of it." ”

"Then it's no wonder, you are now both a national teacher and a royal historian, and I heard that my father will give you a knighthood...... With your current status, if you don't do practical things in the court, you can't see you every day, you should have more important things to do...... Did your father make you concentrate on alchemy? ”

Princess Xianyi's question made Yang Yun not know how to answer for a while.

In fact, it was really not Li Longji who forced him to alchemy, but he found an excuse not to pay attention to the court, so that he had the opportunity to cross thousands of mountains and thousands of miles at night, appear on the South American continent, and open up a new world.

"Yes."

Yang Yun replied, and could only try to say it according to Princess Xianyi's idea.

Anyway, whether it is or not, Princess Xianyi will definitely not be able to find Li Longji for verification.

"The princess came to the mansion early in the morning to supervise the alchemy for His Majesty? Or is there something else that matters? As I explained earlier, I may have important things to attend to. ”

Yang Yun didn't want to get too entangled with Princess Xianyi, so he pondered to get to the point as soon as possible.

Princess Xianyi looked at Yang Yun, her face tightened slightly, and she sighed lightly: "Now my father favors your sister, I heard that my father always goes to Xuannu Temple, and your sister has become a real concubine......"

Yang Yun thought to himself, do you still need you to remind me of these things?

I know much more about the palace than you do.

"I want to ask you, when did the matter of the father's establishment of the crown prince come to an end?" Princess Xianyi asks a question that seems to be serious, but not necessarily the real purpose of the trip.

Yang Yun didn't think about it, and shook his head directly: "Your Majesty's arrangement, how can a little person like me know?" His Majesty has never mentioned this kind of thing to me, and the princess asked the wrong person. ”

Princess Xianyi said: "Then I will let you help my eighteenth brother become the prince now, are you willing?" ”

Yang Yun pondered for a moment, would Princess Xianyi come to him specifically for this matter.

The answer is that there is this possibility, but it should not be the ultimate goal of Princess Xianyi, in his opinion, Princess Xianyi has more important things, which is just a secondary topic.

"With my current status, it is inconvenient to participate in any dispute between the prince and the prince, and even I don't even have the slightest right to speak in the court, so the princess really shouldn't ask."

Yang Yun could only show that he was soft-spoken, and did not directly refuse Princess Xianyi.

Princess Xianyi squinted at Yang Yun, and her eyes suddenly became a little sad, as if she was feeling sorry for her mother's death, or maybe she was sad for her own fate.

"Princess?"

Yang Yun saw that Princess Xianyi was a little distracted, so he couldn't help but remind him.

Princess Xianyi smiled reluctantly, and her voice was slight: "I...... I'm getting married. ”

This news was a bit sudden for Yang Yun.

Is Xianyi going to marry?

Why haven't I heard any rumors before?

"My father just sent someone to inform me, hoping that I can fulfill my mother's last wish as soon as possible and marry a good family...... The eighteenth brother's wedding will also be held in the near future, but the eighteenth brother always thinks about your sister. ”

Princess Xianyi knew that Yang Yuhuan had now become Li Longji's de facto concubine and had a mother-son relationship with King Shou, but she still said that, and it seemed that she didn't shy away from anything.

But she never said who she was going to marry.

She didn't say it, Yang Yun didn't know if she should ask, there are always some things that need to be avoided, as a relative, who does the father-in-law want to marry, and what does it have to do with him?

"It's also a good thing that the princess and His Royal Highness King Shou can get married earlier." Yang Yun said casually.

Princess Xianyi's face was a little aggrieved and a little lost, and her voice was low: "But I never wanted to get married, I just want to be a Taoist aunt, to be able to stay in front of the Taoist statue for a long time, and to participate in the Taoism...... Incredible, right? ”

Yang Yun thought to himself, what is unimaginable about this?

Isn't that something you've mentioned before?

"As a princess, I have pressure that others don't have to bear, and I want to get rid of it, just like women who don't want to get married...... Or maybe I just don't want to get married, as for being a Taoist aunt or a nun, there is no essential difference, what about the Green Lantern Ancient Buddha? ”

When Princess Xianyi said this, it seemed that she had seen through the red dust.

Yang Yun's mouth opened slightly, and he didn't comment on Princess Xianyi's outlook on life.

"It seems that our personalities are very similar, you can stay alone even when you get married!" Princess Xianyi's face improved slightly, and her eyes still fell on Yang Yun.

Yang Yun smiled bitterly a little and said, "The princess is smiling." ”

After Princess Xianyi said this, she seemed to have finally let go of the big stone in her heart, sighed lightly, and said: "It's still the same sentence, I hope you help my eighteenth brother, only you can help him ascend to the position of the crown prince, and no one else has this ability." ”

"I've said everything I have to say, I'll go first."

After speaking, Princess Xianyi turned around and left, leaving a fragrant breeze.

But Yang Yun didn't understand that Princess Xianyi came and went in a hurry like this, really just for Li Mao to be a lobbyist and invite him to be a staff member?

Knowing that you can't do it, but you come to run into a wall again and again, or in the case of the two sides fighting each other, are you a princess too forgetful?

……

……

After sending Princess Xianyi away, Yang Yun still didn't think about it.

I always feel that there is something that I have overlooked.

At this moment, Wu Yuan came out of the room, and Yang Yun had noticed that Wu Yuan had been hanging around the door, probably eavesdropping on his conversation with Princess Xianyi.

"Master."

Wu Yuan stepped forward to salute Yang Yun.

Yang Yun waved his hand and said, "It's not a big deal, Princess Xianyi wants me to help King Shou become the crown prince...... It's none of your business, go and rest early, it should be busy tonight. ”

Yang Yun said, and also wanted to go to bed after washing.

Suddenly, Wu Yuan said thoughtfully: "The princess should have a soft spot for the master. ”

"What did you say?"

Yang Yun suddenly turned around and looked at Wu Yuan with a frown.

Wu Yuan turned his head sideways and said to Yang Yun seriously: "The disciple is shallow, the master can not listen, but with the disciple's observation of the princess, the princess has always cared about the master, and she has helped the master several times, although it may not be what the master wants...... Now that she is about to get married, she will tell her master first, and she must be very concerned about her master's opinion. ”

"Huh."

When Yang Yun heard Wu Yuan's analysis, he couldn't do anything but smile bitterly.

I don't want to know, I want to be scared.

Yang Yun prides himself on being a smart person, but he has never pondered his relationship problems.

His marriage to Zhang Yu and Li Konger was almost entirely political, and the personal emotional factor was very low, so low that Yang Yun ignored it.

But when it came to the question of Princess Xianyi's feelings, Yang Yun felt a strange tingling feeling in his heart.

It was something he had never experienced before.
