The moment the knife slashed down, black blood gushed out, and Zilong, who was watching from the side, suddenly turned white.

Some people have been through a hundred battles and have no calculation for killing, but when they see blood coming out of familiar people, their legs immediately weaken, and Zilong is obviously this kind of person.

Ziqingshu is still his master, like a brother, he has been instilled with loyalty since he was a child, and now when he sees a lot of blood coming out of Ziqingshu's body, he almost can't hold back the power of the wilderness in his body to twist Liu Jun's neck.

Fortunately, Liu Jun repeated the severity of the problem repeatedly before the operation, and Zilong finally controlled himself.

The black blood from the big wound covered the surgical vision, and Liu Jun couldn't see the internal situation at all, but he didn't panic and said calmly: "Suction tube." ”

When there is no electric blood pump and absorbent cotton, how can you clear the surgical field? After thinking about it, Liu Jun felt that it would be better to use a suction cartridge, a ceramic suction cartridge the size of a baby's arm, sealed with leather, barely usable.

Liu Jun also made some improvements to the needle nozzle part of the suction tube, adding two small sleek notches to prevent the suction from causing damage to the organs.

Li Shu leaned over with a suction tube, trembling nervously and putting the suction mouth towards the wound, but was stopped by Liu Jun sternly: "Your hands are shaking like this, it will hurt the wound, take a deep breath and calm down, I have taught you many times, if you can't do it, let Li Shu come." ”

Liu Jun's stern tone startled the purple dragon on the side, and he couldn't bear to glance at Li Shu, a little girl who was less than nine years old, not much taller than the platform, and now she was standing on a special heightened platform, she was already very nervous and scared, and her eyes were red when she was trained by Liu Junyi.

Liu Jun was unmoved, stared at her sternly, and said sharply: "Take a deep breath, the patient is losing blood every second when he lies on the bed, every second you hesitate, the patient may lose blood and die, you have practiced many times, and you have also practiced with livestock, you can, now you just need to overcome the fear and tension in your heart, do you want to watch the patient die?" ”

When he first crossed over, Liu Jun doted on these two daughters very much, he himself was a person who liked daughters, he used to have children with his classmates, and when he talked about similar topics, he categorically said that he wanted a daughter.

But now, he has far stricter requirements for his daughters than his sons, whether it is morning and evening classes, archery or culture, he has more homework than his sons, because he realizes that in this era, it is much more difficult for girls to survive than men, and spoiling them is equivalent to harming them.

This day and age does not even have time for them to grow up, and if they cannot protect themselves, the fate is even more tragic than that of livestock.

Li Shu took a deep breath hard, the tears swirling in her eyes flowed, but her hands miraculously did not tremble, she steadily put the suction mouth against the wound, and sucked back while silently shedding tears, the dirty blood on the wound was quickly sucked clean, and the surgical field was cleared.

ran down the platform, squeezed the dirty blood from the suction tube, and then placed it on the tray, Li Shu opened the mask on her mouth and spit it in the dirty blood bucket under the stage. After all, livestock cannot be compared with a living person, and no matter how much you practice, it is impossible to ignore this shock for the first time.

Liu Jun said affirmatively: "Very good, well done." "I didn't stop in my hands, and I took advantage of the gap between the opening of the surgical field of view to operate quickly.

Liu Jun used the operation technique of light bleeding, after sucking out the first wave of dirty blood, the amount of bleeding in the back was much less, and the operation was completed in about 30 seconds, and then sutured.

The suture is made of sheep intestines, and the sutures obtained after processing fresh sheep intestines through a series of methods have the advantage that they can be automatically degraded, and there is no need to remove sutures after wound healing, and they can be used to suture visceral blood vessels and intestines.

But the shortcomings are also obvious, that is, the strength is not enough, and it is very reluctant to use it to sew the skin and flesh, but Liu Jun has no other thread on his hands, and he was originally going to get some silk thread or twine, but unfortunately before he could get it, the barbarians came.

Therefore, as a last resort, Liu Jun used a more intensive improved intermittent vertical mattress suture method to improve the strength, as long as there was no high-intensity activity before healing, he could barely make do with it, and the stitches could not be removed.

This was the most serious injury on Ziqingshu's body, and it was also one of the few that could be fatal, and there were five more fatal wounds, two of which had two arrows with barbs dug up, one of which hooked an artery.

Fortunately, Zilong and these people have experience and did not dial hard, otherwise they would have cut off the arteries, and Ziqingshu would not have been able to survive until now.

Zilong, who was watching from the side, was pale at first, then Tie Qing, and by the time the operation was completed, he was already sweating profusely, and then looked at Liu Jun's eyes unconsciously with a trace of fear.

"Young master, a woman who can cut and sew up on a person so calmly is terrible, you can't bear it."
