Li Shizhen heard Luo Yu say this, so she retracted her gaze, stretched out her hand to help Zhang Yuan take her pulse, and nodded after a while: "It's no big deal, no need to blood, little lady, help take care of it." ”

Jin E nodded hurriedly, came to Zhang Yuan's side, and wiped the sweat on her face.

Luo Yu breathed a sigh of relief, pulled the needle out of his hand, the blood vessels were still bleeding, he hurriedly pressed the needle with a linen, shook his head a little dizzy, sat on the stool, and closed his eyes to rest after drinking two large mouthfuls of water.

Don't worry about Zhang Yuan's needle, Li Shizhen will take care of it, the only thing I am a little worried about now is the little girl Jin E, from her adoring eyes, it seems that Luo Yu is a fairy.

Ignoring the dizziness, he said, "Sir, do you know how many types of human blood there are?" ”

Li Shizhen, who helped Zhang Yuan deal with the needle, was stunned for a moment when he heard this question, and said slowly: "The old man only knows that the blood of his parents can be dissolved in water with the blood of his children, and the blood of other unrelated people is incompatible. ”

"Yes, I have to be a popularization teacher again, I hope this shallow knowledge of mine can inspire your elderly and save more lives." Luo Yu thought so in his heart, but said in his mouth: "There is a book in the younger generation's family that records that human blood is so large that it can be divided into four common categories: 'A, B, C, and D'. ”

Speaking of this, he paused so that Li Shizhen, who was sitting on the side, could record, and when he saw that he had finished writing, he said, "Sir, why don't you hand it over to the juniors to write it and then give it to you for reference?" ”

Li Shizhen said: "Say it, the old man will remember it more clearly when he writes it!" ”

Luo Yu was no longer reluctant, and continued: "Blood type A corresponds to the input of blood type A, blood type B corresponds to blood type B, blood type C is more special, it can only transfuse blood type C, but it can be exported to three other common blood types." The same is true for blood type D, which can only be transfused with type D. ”

Li Shizhen remembered it before saying, "How do you distinguish these four blood types?" ”

Luo Yu smiled bitterly: "I won't tell you, the juniors don't have the tools to tell now, they only know that they are blood type C, so as long as Zhang Yuan is not a rare special blood type, the juniors can give her a blood transfusion." ”

Li Shizhen nodded and said, "I see, what are the special blood types you just mentioned?" ”

Luo Yu said: "It's relatively rare, it's hard to have one or two out of a million people, if they are injured and bleeding too much and can't find the same blood type, they can only wait to die." ”

Li Shizhen wrote it down in the notebook again, thought for a while, and said, "How do you know how much blood a person has lost to be considered excessive blood loss?" ”

This old master is about to clean up the little inventory Luo Yu has, and he will not give up, alas, forget it, he should make a little contribution to Huaxia medicine, and say it all so that their doctors can study it.

After pondering for a while, he said: "An adult's blood volume is about five bowls, which is the big bowl we have for vegetables, when the blood loss reaches more than one bowl and less than three bowls, it is considered excessive blood loss, and if the treatment is timely, there is a chance to survive." ”

Li Shizhen asked: "If you have more than three bowls, you can't be saved?" ”

Luo Yu smiled bitterly: "That's true, the gods are difficult to save, and the younger generation saw that she could still breathe, so they didn't hesitate to risk giving her a blood transfusion." ”

Li Shizhen thought of an important question again: "Human blood is quantitative, how can the lost blood be replenished?" ”

Luo Yu smiled: "The human body is wonderful, our spine has hematopoietic function, and the lost blood will be slowly created to maintain the daily needs of the human body." ”

Li Shizhen asked again: "In this way, a person with a severed limb can also be a blood transfusion?" ”

Luo Yu said: "As long as the appropriate amount, anyone can become a blood transfusion, but there are hidden dangers, some diseases will be hidden in the blood and transmitted to the blood recipient, so as a last resort, in the case of not being able to verify whether the blood transfuse has a disease, the younger generation is not recommended to use this method." ”

Li Shizhen still wanted to ask again, Zhang Yuan had woken up slowly, Jin E heard their conversation, and understood the reason, although it was not as beautiful as imagined, but still admired Luo Yu's profound knowledge.

When she saw Zhang Yuan wake up, she hurriedly shouted, "Uncle Li, she's awake!" ”

Li Shizhen didn't care to ask any more, put down the pen and walked over, observed for a while, and said, "Okay, the little lady will help her change into clean clothes, and the bed board will also be changed!" After speaking, he pulled Luo Yu out.

As soon as the two of them went out, a general in black armor walked quickly, Luo Yu saw the person who came, and said happily: "Uncle Niu, long time no see!" ”

As he spoke, he greeted him, but before he had time to salute, Niu Jinda laughed and said, "You kid, long time no see!" ”

The eldest grandson Wuji also walked over quickly, saluted Niu Jinda and said, "I've seen Uncle Niu!" ”

Niu Jinda waved his hand, handed him a letter and said, "Wuji boy, your daughter-in-law asked the old man to bring you a letter, you take it first and read it, and drink two cups together in the evening." ”

The eldest grandson Wuji took the letter with a smile and said, "Thank you, Uncle Niu!" So he stepped aside and opened the letter.

Luo Yu introduced Li Shizhen to Niu Jinda, and the two exchanged pleasantries for a while, before Li Shizhen was called to change the dressing, and the two sympathized with each other, which made Luo Yu laugh.

Niu Jinda patted Luo Yu's head and scolded with a smile: "This folk doctor has admired him for a long time, what's wrong with talking to him a few more words?" Don't you kid want your husband to help you? ”

Luo Yu begged for mercy: "Uncle Niu, the little nephew doesn't dare, you have been tired all the way to the saddle horse, please go in and have a cup of tea first, there is just something I want to ask!" ”

Niu Jinda said: "It's almost the same, lead the way!" ”

The two came to the school captain's mansion while talking, and Luo Yu made tea and served it to Niu Jinda and said with a smile: "Uncle Niu, why did Tang Gong recall Xiuning back to Taiyuan?" ”

Niu Jinda took a sip of tea and said angrily: "Are you really stupid? Of course, Xiuning went back to Taiyuan for you! ”

Luo Yu was stunned and said: "The little nephew really doesn't know the reason, and I ask Uncle Niu to solve the puzzle!" ”

Niu Jinda hated iron and said: "You kid, why don't you understand the world at all?" Tang Gong summoned Xiuning back, he wanted you to go to Taiyuan to propose marriage, have you ever seen a couple who have not married go back to their parents' house together? ”

Only then did Luo Yu understand why the three girls didn't tell him the reason, Li Xiuning's shy appearance after reading the letter should have guessed that it was this matter, and he was stupid to ask others.

should really be beaten, no wonder Gongsun Xiaomei said those words, but it doesn't seem to be to blame Luo Yu, he doesn't know the customs of this era, so he is now scolded by Niu Jinda and doesn't dare to reply.

After Niu Jinda scolded twice, he said earnestly: "The Li family has been noble for generations, Xiuning is a heroine, you are happy with each other, you can tie the knot, of course the old man is happy to see it, in this troubled world, human life is like a mustard, Xiuning is a general, it is difficult to guarantee that he will fight on the battlefield in the future, can you think about the preparation to spend the rest of your life with her?" ”

Luo Yu was a little in a trance, to be honest, before coming to this time and space, he never thought that he would experience such a cruel thing, these days with Li Xiuning, he escaped death several times, and good luck always ends up that day.

If he continues to fight, if Li Xiuning or himself sacrifices one day, the one left behind will definitely be in pain, just like Chai Shao in his original time and space, he was depressed all day long, and finally swallowed his last breath in his thoughts, and he was only fifty years old.

At this moment, Niu Jinda asked, and he didn't know how to answer for a while, so he only muttered: "Uncle Niu, is it possible that we will not go to the battlefield again after we get married?" ”

As soon as Niu Jinda wanted to answer, Li Shimin, who attacked the Mongolian military camp at night, hurriedly ran in, and did not salute Niu Jinda, but pulled Luo Yu and walked out, and said urgently: "Yu Dong was seriously injured by the explosion in order to save me, you come with me to take a look!" ”

When Luo Yu heard this, he didn't ask anymore, and hurriedly followed Li Shimin towards the wing, and as soon as he entered the door, Li Shizhen arrived with a medicine box on his back.

Yu Dong's back was full of traces of gunpowder burns, red and white, shocking at a glance, Li Shizhen had never seen such an injury, so he had to protect Yu Dong's heart with a silver needle first, and then start debridement.

Luo Yu didn't know what to do for a while, now there is no alcohol, there is no way to disinfect.

Suddenly a flash flashed in his mind, by the way, alcohol, Niu Jinda should have brought wine over, it should be no problem to refine the alcohol, thinking of this, he said to Li Shizhen: "Sir, you stabilize his heart first, and the juniors will find some debridement drugs." ”

didn't wait for Li Shizhen to answer, and strode to find Niu Jinda to ask for wine, and it would take some time to refine the alcohol.

It happened that Niu Jinda also went out and wanted to come over to have a look, the two met at the door, Luo Yu saluted and said, "Uncle Niu, how much wine did you bring here?" ”

Niu Jinda was also a little confused for a while, so when he asked, he said: "Not much, only five altars, what, do you want to drink?" ”

Luo Yu hurriedly said: "Please let them send all the wine here, the little nephew needs it urgently." With that, he turned around and ordered one of the Songta defenders to build a large stove in the patio and carry two cauldrons and a round bath barrel.

It's easy to distill alcohol, but now the tools are not very handy, so you have to take an arm-thick bamboo, split it from it, knock off the middle of the bamboo, and soak it in boiling water to sterilize.

There are many people to do things, and while Luo Yu is doing a good job of bamboo, the Songta defenders have sent all the needs over.

Luo Yu can't fake other things, he has the time to tell others, and he has done it himself.

According to the width of the bamboo, a diagonal opening is made in the middle of the round bath tub, one is to fix the bamboo, and the other is that the distilled alcohol can flow down the bamboo into the container connected to the bamboo.

The bottom of the tub was to be removed, and when he was busy with this, he had already asked the sergeant to bring cold water and pour all the wine into the cauldron below.

Then pour the bucket with boiling water twice, place it on top of the iron pot full of wine, fix the bamboo, and call two sergeants to carry another large iron pot that has been washed clean on top of the bucket and place it, adding half a pot of cold water.

Everything was ready, a raging fire was already burning below, Luo Yu found another big bowl, and came to the end of the bamboo to receive alcohol.

Fortunately, distilled water dripped, and the first half bowl could not be wanted, there were too many impurities.

At this time, the liquor brewed was made from sorghum and wheat, and it was only fermented liquor, and the degree was not high, but it was the best stock solution for distilling highly refined liquor, and it was rich in starch.

The fire was very big, and the heat around it was boiling, Luo Yu followed the alcohol wholeheartedly, a bowl was almost full, called a sergeant, asked him to move a stool, put the bowl and collect the alcohol.

Strictly speaking, this is not pure alcohol, but only highly distilled spirit, but it can be used as medical alcohol disinfection, and it is completely fine to use it for debridement.

Served a large bowl of alcohol to Li Shizhen and said, "This is a debridement potion, you can use a cloth to stick it on." ”

He turned his head to Yu Dongdao, who was already confused: "It's a little painful, you bear with it!" ”

Yu Dong nodded reluctantly, and screamed before he was ready, it turned out that Li Shizhen had already begun to wipe the terrible burns with a cloth sticky with alcohol.

Li Shimin couldn't see it, and before Yu Dong's second scream came out, he was directly knocked unconscious.

This kind of heart-piercing pain Luo Yu knows that this is not real high-purity alcohol, but when he touches the wound directly, the pain is also uncomfortable.

Luo Yu couldn't bear to look at it anymore, Yu Dong's back injury was destined to leave scars, and it would affect his future life.

The special combat team has suffered heavy losses, and it seems that it is really going to set up an institution to deal with the aftermath, otherwise there will be more people who will be injured and sacrificed in the future, and their family life will be very troublesome.

The distillation continued, and the water in the pot above had become hot, and he ordered someone to add half a bucket of cold water to it.

Li Shimin ran out and brought two bowls of alcohol in, and Luo Yu ordered to use the wine jar to catch the alcohol, and seal the jar for preservation after it was full.

After collecting a full jar of alcohol, Li Shizhen finally dragged out tiredly.

Luo Yu didn't dare to ask, only expected him to tell the good news, Yu Dong only had an old mother, a wife, and a young child in his family.

Seeing Li Shizhen nodding with relief, Luo Yu relieved himself and happily came to Niu Jinda: "Uncle Niu, thank you for the wine!" ”

Niu Jinda said with a smile: "It's okay, you kid has to pay the old man a few jars of such spirits, it's so fragrant!" ”

Only then did Luo Yu remember that the appearance of a high number of distilled spirits would make many drunkards rush to it and couldn't stop.

Li Shizhen said out of place: "The old man wants all these things, if you want to drink, you need to find another way." ”

Yes, one for drinking, the other for medicine, I hope they don't quarrel!
