Chest penetrating injuries are difficult to operate even in modern times, but fortunately, it is caused by a sharp weapon, and the incision is flat, and it can be completed with complete sutures from the inside out.

There are almost no major wounds in the ribs and thoracic cavity, the only difficulty is the wound that penetrates the lungs, and the hemorrhagic shock caused by a large amount of blood loss, plus the tools are relatively rudimentary, and the surgical knife is removed from a pair of scissors.

To be honest, this kind of chest penetrating wound is actually not particularly rare in some martial arts works, and under normal circumstances, just find a doctor to smear some gold sore medicine and it will recover directly... What the hell is that, it's just nonsense!

In ancient times, not to mention the penetrating wound on the chest, even if the wound on the limbs was a little deeper, it could be regarded as one foot stepping into the ghost gate, and to survive, in addition to relying on human will, it also depended on the strength of the doctor who treated it.

It can be said that there are only two ways for ancient people to do this kind of wound, one is to smear gold sore medicine, and the second is to wait for death... In fact, both of them are not much different from waiting for death, except that the first one is to smear a little gold sore medicine, if the willpower is strong enough, you may be able to survive if you get through it, but if you can't get through it, you can only hehe.

Before the operation, Yi Yan still had a blood transfusion first, although the wound had been treated, at least within an hour, the wound would not bleed anymore, but there was too much blood in this guy's body, and he had to replenish it, otherwise he wouldn't be able to hold it out at all.

Therefore, after seeking Dongfang Weiming's consent, Yi Yan used a knife that had been sterilized to wipe it directly on Dongfang Weiming's arm, and immediately the blood flowed like an infusion, and the blood rushed out, and Yi Yan, who had already been prepared, caught it below... Speaking of which, Dongfang Weiming, this kid is really stupid!

After learning that a blood transfusion was needed, this guy immediately agreed without saying a word, although the person in front of him who didn't know his life and death did have an extraordinary relationship with Dongfang Weiming, but according to the situation, Dongfang Weiming should not know him, but now, Dongfang Weiming is willing to give his blood so generously for a stranger.

And in this world where there is no concept of blood transfusion at all, I am willing to believe that Yi Yan can do it, and I really don't know what to say about this trust, whether to call him stupid or to say that he... Forget it...

After taking a full three or four hundred milliliters of blood, Yi Yan clicked two of the acupuncture points on Dongfang Weiming's arm, and the arm that was originally bleeding suddenly stopped bleeding, and at the same time asked Dongfang Weiming to eat the blood tonic pill he had just made before, and let him treat the wound first and rest well.

Dongfang Weiming's wound is actually not serious, the most important thing is because Yi Yan cut his major artery, so the blood will not stop, and after the operation, Yi Yan has to suture the wound to Dongfang Weiming first, otherwise wait until the power of the acupuncture point disappears, and the bleeding will be serious.

A large bowl full of blood was completely poured into the bamboo tube needle tube that was made before, the blood foam in it was removed, and the needle that was nearly two or three mm thick was directly pierced, and the veins in the guy's hand began to be infused with blood.

Generally speaking, after the human blood comes into contact with the air outside the body, it will only take about three minutes to begin to coagulate, and there are other factors, which cause Yi Yan to control the time of blood transfusion to less than two minutes, and at the same time, all the blood cannot be injected into the patient's body, because Yi Yan's way of drawing blood does not meet the regulations, but there is no way, now the conditions are so simple, and it can only be handled simply.

After the blood transfusion was completed, Yi Yan picked up fish bones and silk, silk is difficult to find, it is not difficult to find, it is not difficult to find, and finally Gu Yuexuan still found a silk towel from the village chief's son... Who knows why a big man would have such a thing?

As for the fish bones, they were made from the carp caught in the river by Dongfang Weiming, and after sterilization and perforation, they can already be used as needles to suture wounds.

I saw that Yi Yan's hand suddenly shuttled a few times like a phantom, and the wound caused by the blood transfusion had been stitched up, and because it was woven from silk and silk, it can be said that biological protein can be completely absorbed and degraded by the body, so there is no need to consider the problem of removing stitches.

After that, Yi Yan started the real operation, opened the wound he had bandaged before, cleaned the wound with wine, and then directly cut the wound with a knife, which should not be as sharp as a scalpel, in Yi Yan's hands, it seemed to have become a treasure knife that sharpened iron like clay, and with a slight stroke, the flesh and blood were separated instantly.

Then Yi Yan began to cut off the rotten flesh, and after confirming that there was no residue in the wound, after a series of suturing operations, the wound was finally completely sutured, which was very perfect.

After turning over, after all, it is through the wound, it is impossible to only get the front, the back has to be done, the same operation, the same principle, and when the operation is over, the whole process does not exceed half an hour, including blood transfusion, making suture tools, cleaning the wound, judging how to suture the wound according to the situation, and finally ending completely, all the process only took 30 minutes...

This speed is really against the sky, such a wound, even if it is assisted by high-tech and complete equipment in modern times, it will take several hours to complete, but Yi Yan's speed is too fast, the action is extremely fast, and all the processes are in place in one step like a cloud of peers, as if he has practiced this operation thousands of times.

Only he knew that a day ago, he was just an otaku in bed...

The heaviest wounds have been treated, and the next thing is to condition the body, as well as internal injuries, all kinds of problems, but this is only a minor problem.

When Yi Yan raised his head after doing everything, at this moment he found Gu Yuexuan standing next to him and Li Langzhong in the village, both of them looked at him as if they were stupid.

Although Dongfang Weiming was also watching from the side, he didn't have much reaction, but he just felt that Yi Yan's performance just now was particularly magical.

And Gu Yuexuan understands that he can only describe Yi Yan's performance just now, and at the same time, he is even more curious, what is Yi Yan's identity?

Yi Yan knew by looking at their expressions that he was afraid that his methods just now were a little surprising to everyone, no wonder, even if his current medical skills were in the future and modern times, I am afraid that they would be superhuman existences, they were surprised, it was too normal.

However, Yi Yan didn't forget that he still had something to do, and took the rest of the silk to stitch up the wound on Dongfang Weiming's hand, and now Yi Yan can finally take a rest.
