Duan Shaojun, who was picking up the sheep intestines that had been made with great difficulty, and carefully examined whether there was any insect moth, his eyes darkened, and he glared viciously at this beast brother who didn't know what the hell stuffed in his brain was. "These instruments are just surgical instruments, not used to stuff the belly to play, you are not money when I am money."

The abbot couldn't help but glared at Ximen Dongliang viciously. "Stinky boy, don't talk nonsense if you don't know, give the old man a flash and cool off. Shaojun, this thing is like a thread, but why doesn't it feel like it? ”

"This is sheep intestines, a thread made of the casing maker of sheep's intestines, such a thread, even if it is left in the human body, will not produce much rejection, and the most important thing is that the human body can absorb this thread without cutting the wound in order to break the line......" Duan Shaojun's explanation made a Datang medical worker like a book from heaven.

The abbot of the dream grinned widely, and his triangular eyes were about to become trapezoidal. "You're saying the thread is made from sheep's intestines? It can also be used to sew it into the inside of the stomach......"

"That's, or do you think?" Duan Shaojun said angrily, there is no way, anyone who encounters too many mentally handicapped problems will be as impatient as him.

Meng Yu glared at Duan Shaojun, but surprisingly did not get angry. But the shock in my heart was really indescribable, and I admired the unknown monk who educated Duan Shaojun with his medical skills. If it weren't for Duan Shaojun telling himself, the high monk had disappeared without a trace, and he couldn't find it for several months. There is an impulse to drag Duan Shaojun to find the unknown monk who has the best medical skills.

"Brother Simon, help me get a basin of boiling water, remember to boil the kind, the hotter the better." Duan Shaojun finally took out a metal syringe made entirely of metal. Then, a needle about two millimeters in diameter is carefully clamped out of a small iron box with tweezers, and then placed at the injection end of the metal syringe.

This thing is really made with great effort and painstaking effort, it is first cut off a piece of iron sheet, and then a thin sewing needle is wrapped in the middle and then beaten countless times before finally taking shape.

Because of the craftsmanship of this era, this injection needle is terrifyingly thick compared to the injection needles of later generations, but this is already the limit, at least it will not have the slightest problem to puncture the vein at the elbow.

Duan Shaojun specially spent ten taels of silver to make such a needle and invited an old craftsman who specializes in making headdresses. And for each needle, the salary alone is one or two pieces of silver. Alas, when I think of this kind of thing, which in later generations would not even cost a dime, it is so expensive in this era.

The fifty needles in the needle box alone cost fifty taels of silver, which was enough for a family of five to live well in this era for five or six years. Every time he thought of this, Duan Shaojun would feel extremely congested, and his eyes looked at the needle with tears in his eyes, as if admiring the silver ingot.

"What are you doing with this thing?" After all, the abbot of the dream couldn't hold back his extremely strong curiosity and asked again.

"This is something that is used to draw blood, or injections......"

"Blood draws?!" Everyone gasped in unison. "You mean stabbing people with this thing?"

"Wouldn't it? Doesn't it hurt to prick someone with such a thick needle? ”

A vote of people chattered crookedly, Duan Shaojun didn't bother to pay attention to it, took the boiling water basin handed by Ximen Dongliang, and threw ten needles and three syringes into it.

While disinfecting, people went to invite the shopkeeper Xu, who had been guarding Xu Qianxun in the back, to come over. "Surgery will bleed, I need to prepare blood for your son."

"With my blood." Shopkeeper Xu replied without thinking about it. Then he rolled up his sleeves. "Don't go get bowls and knives yet."

Duan Shaojun was shocked, oh no, shocked. His eyes widened. "Stop, stop, what are you going to do?"

"Bloodletting, didn't you say you wanted me to prepare blood for my son?" Shopkeeper Xu was stunned for a moment, and then continued to roll up his sleeves.

"I'm ...... I said shopkeeper Xu, I mean to prepare a blood transfusion for your son, if you don't do that, even if you take a knife and put ten bowls of blood, it's useless. Duan Shaojun said helplessly. Then he used tweezers to pick up a needle from the boiling water basin and shook it at the shopkeeper. "I need to use this thing to draw blood through your veins to see if your and your son's blood will be rejected."

"My mother...... shopkeeper Xu looked at the thick needle, and the needle that was thicker than a toothpick, and couldn't help but turn a little pale. You mean you're going to stab me with this thing? ”

"It's not pricking you, it's pricking your veins. Don't talk nonsense, your son is still waiting for help. Duan Shaojun shouted angrily.

Soon, about ten milliliters of blood were drawn from the veins of the shopkeeper Xu. Three tubes of blood were drawn from Xu's shopkeeper's relatives. After that, he went to Xu Qianxun and drew about ten milliliters of blood. Each in a small crystal bottle. No way, there is no glass in this era, but fortunately, all kinds of crystal ornaments and utensils are at least being made.

After putting it in, he covered it with a stopper, stuffed it into a small bag stuffed with cotton flowers, and tied a long rope, Duan Shaojun glanced at everyone. "Brother Simon, I'm afraid I have to ask you."

“…… You mean let me stand here and play with this bag? Ximen Dongliang looked at the cowhide bag blankly and asked with a dull expression.

"Of course it's not playing, I need you to help me isolate the serum and red blood cells." Duan Shaojun rubbed his brows, I don't know if it's the nth time I've explained today.

Woowoo...... As Brother Simon was flicking the cowhide bag with his strange power comparable to Popeye, and the more people there were, the more energetic the goods became, and they actually hummed and jumped there as if they were playing nine whips, and everyone looked more and more confused. It's like healing, it's like juggling.

“…… I said, Shaojun, what is the use of you doing this? The abbot of the dream looked at Ximen Dongliang playing there with a black line, and resisted the urge to rush over and beat this fool, and asked Duan Shaojun in a low voice.

Shopkeeper Xu also squeezed his head over, and looked at Duan Shaojun with a worried and suspicious expression, he really couldn't figure out what these things had to do with his son's passive surgery.

"He did this for a reason, because I needed to be matched with Xu Gongzi to facilitate the transfusion of the same type of blood for him."

"I'm his father, can his blood be different from mine?" The shopkeeper Xu suddenly widened his eyes, and the spittle stars flew sideways.

"Your son looks so much like you, if it's not your son, whose son can it be?" The abbot of the dream snorted angrily.

"It's true that he is your son, but you and his blood type are not necessarily the same, human blood types are roughly divided into three or four, one is type A, one is type B, one is type A, and one is type O...... Anyway, I need to find a blood that won't make all the blood in your son's veins clot together as soon as it's transfused. ”

It took a long time to explain, not to mention that the field experiment was more effective. When Duan Shaojun carefully used a needle to extract a little red blood cell from Xu Qianxun's already separated blood, and dripped out several other tubes of blood.

In front of more than a dozen pairs of round eyes, five tubes of serum were faintly red, while the other three tubes condensed into strange flocculents.
