The golden needle pricked the fingertip, squeezed out the blood droplets, and dripped them into the plain white tea cup.

This tea cup is made of the best blue and white porcelain produced in Jingdezhen, which is also called "shadow green" in later generations. The extremely thin body is matched with a clear and pure white glaze. When exposed to light, it is translucent inside and outside, crystal clear and moist like jade. Now it is used

Let's make a blood test cup.

Including Zhao Mengqi himself, six people dropped blood into different teacups, and then took blood from Qian Duo's hand and poured it in one drop at a time.

Qian Duo lost too much blood and it was a bit difficult to get blood. Chongtai doctor used massage techniques to squeeze out seven drops. The extra drop was specially used for comparison.

Bloodshed to recognize relatives?

Imperial Physician Chong was no stranger to the situation before him. The method of identifying relatives by shedding blood had already appeared in the Three Kingdoms period, and had been included in Song Ci's "Collection of Clearing Wrongdoes". Of course, later generations knew that this method was unreliable, but it also showed that the Chinese people had already

Pay attention to the genetic relationship between blood relatives and start trying to apply it.

I was very confused about the relationship between the "blood test" mentioned by King Yan and the blood test to identify relatives, but Dr. Chong also knew that this was not the time to ask questions, so he kept it in mind.

Zhao Mengqi knew that after blood is dropped into water and the red blood cells are diluted, all blood types will be mixed together, so there is no water in the cup.

The method he used was based on the principle that there are antibodies and antigens in the blood against other blood types. When blood of two different blood types is mixed, the antibodies and antigens react with each other to form two precipitates.

He had never seen the specific phenomenon, so he had to use Qian Duo's own blood to compare and observe with the six mixed groups.

The tea cup has relatively good light transmittance, and the subtle reactions of the blood inside can be clearly observed.

Zhao Mengqi was careful and meticulous, and took the trouble to compare the two groups. Finally, he found that only two groups had no visible changes, which most likely ruled out the possibility that Qian Duo had blood types AB and O.

Coincidentally, judging from the marks on the tea cups, one of the two groups belonged to Zhao Mengqi, the other belonged to Wanwan, and Wu Qiong and the others were not suitable.

"I don't think there is any need for you anymore. You can go out first."

When Wu Qiong and the other four heard this, they were very sorry and hated that they had no chance to bleed, but they could only follow the order and leave the west wing.

Wanwan was relieved, "So, my blood can be used? That's great. Without further ado, let's get the blood and give it to Duo Niang."

"Your Highness, how can we transport this blood? Should we cut the blood vessels and stick them together?"

Doctor Chong was slightly excited at this time. If blood transfusion is effective, it will save countless lives in the future. With this achievement, surgery, which has always been despised by others, will truly establish its position in medicine.

"If you cut a blood vessel, it's not a blood transfusion, but a bloodletting." Zhao Mengqi responded casually, and then looked at Wanwan, "I thought about it and used mine first. Maybe my magical self-healing ability can be used through

Blood helps Chando."

Wanwan looked stubborn and disagreed. She raised her eyebrows and said anxiously, "But Langjun, you are still injured, how can you lose more blood and essence!? It's better to use my body. My body has always been healthy, and a little blood will do nothing to the body.

No impact."

"Ruochu, don't get excited. This blood transfusion is unprecedented. I'm not sure what the consequences will be. It's safer to use mine. If it's really not enough, I'll take yours..."

All said and done, Wanwan couldn't defeat Zhao Mengqi and had no choice but to compromise.

Immediately, Zhao Mengqi took the evaporated small objects and assembled them himself.

"It looks like a pump..." Dr. Chong looked at it carefully.

These are the syringes that Zhao Mengqi asked craftsmen to research and manufacture as early as Lin'an. There are two sets in total.

The barrel body and the push rod are both made of silver. The piston part of the push rod is wrapped with Eucommia gum. The hollow needle is also made of silver. This thing is the most difficult to make, but in the end it did not stump the skilled craftsmen of the Song Dynasty. After all, those exquisite

Incomparable gold and silver jewelry are also handmade by them.

Compared with the medical needles of later generations, this one is much thicker, but given the conditions, we can only make do with it.

In order to seal, the needle and the syringe are connected using a screw structure, and the barrel has a capacity of approximately fifty or sixty milliliters.

After assembling the syringe, Zhao Mengqi thought about it again and decided to draw some blood from Qian Duo and inject it into himself to see the reaction.

Lifting Qian Duo's hand, revealing the delicate arm, the cyan blood vessels were clearly visible under the skin that could be broken with a finger. After Zhao Mengqi found the right position, he applied alcohol to disinfect it, waited for a while, and then slowly inserted the syringe.

.

The hardness of the silver needle is not very high, so you have to use some skill to penetrate it into the blood vessel smoothly.

After taking out a small half of the tube, Zhao Mengqi stopped, pulled out the needle, and said, "Mini, take a cotton ball and press the needle hole."

Then he raised the needle up and squeezed out any air that might be present. He also said, "This is to prevent air from entering the blood vessels, otherwise it will be very dangerous. You must remember this."

Imperial Physician Chong has been closely watching every move of King Yan, not daring to let go of any details. He nodded his head when he heard the words.

Then Zhao Mengqi operated alone again, inserting the needle into the blood vessel of his left hand, and continued while pushing, "Generally, veins are used for blood collection and injection..."

With a large amount of human anatomy, Dr. Chong Taiyi can be said to be the first person in the world to understand the structure of the human body. Naturally, he also knows the difference between arteries and veins.

After the warm blood entered the body, Zhao Mengqi closed his eyes and began to self-monitor his body.

Common sense told him that the fresher the blood transfusion, the better. On the contrary, there would be more hidden dangers in blood transfusion, but now he could not care about so much.

Everyone looked at Zhao Mengqi anxiously and nervously. The whole room suddenly became quiet, and they wished they could stop breathing...

After a while, Zhao Mengqi opened his eyes and showed a relaxed expression. He stood up and walked for a while. He didn't notice anything unusual. To be cautious, he even asked Dr. Chong to check his pulse.

"I don't see anything wrong!" Dr. Chong was pleasantly surprised.

Zhao Mengqi smiled and said, "It seems that we are lucky. We are half successful."

Seeing that Zhao Mengqi was safe and sound after the blood transfusion, everyone felt miraculous and excited.

"Your Highness is truly a scholar and a man of heaven. He has once again created a good way to save the world and the people. If he concentrates on medicine, he will definitely become a peerless miracle doctor that surpasses Hua Tuo and Bian Que!"

The light in Imperial Physician Chong's eyes was green and faint, like that of a wolf. He really had the urge to pick up the scalpel and break open King Yan's Tianling Cap to take a look.

Under the influence of Zhao Mengqi, he has now accepted the view that human thoughts are controlled by the brain, not the heart.

"I'll leave it to you to be the miracle doctor. I want to be the one who controls the world..." Zhao Mengqi said in a relaxed tone, smiling, "Besides, I haven't really succeeded yet."

"Fourth brother will never fail!" Zhao Han will always be his brother's loyal little fangirl.

Zhao Fei also agreed with a smile, "That's right, fourth brother is the proud son of heaven and will never be defeated!"

Wanwan put her hand into Zhao Mengqi's palm, her eyes were like silk, wrapping around the person in front of her, "Mr. Lang, you must be a treasure given by God, not only for the world, but also for me."

"Haha, if you do this, I will be proud." Zhao Mengqi gently pinched the catkins in his palm, "Okay, now it's time to take the next step, inject my blood into Qian Duo's body and see, well, I need to change it.

I can't do it myself if I can only draw it with my hand, Dr. Chong, please do it."

"Me?" Dr. Chong was a little surprised, but he was also very excited to be able to learn and apply it now.

After taking the syringe, he tried pushing it a few times to feel the strength. After calming down, he began to look for blood vessels in Zhao Mengqi's right arm.

At this time, Zhao Mengqi said, "Pull it from the artery. It will have more nutrients."

He didn't know whether this was scientific or not, but he knew that arterial blood came from the heart and had a higher oxygen content, just like a fully charged battery, so it should be more useful.

Arteries are thicker and tougher, and blood pressure is higher, making it more difficult to stop bleeding if they break.

Dr. Chong hesitated for a moment, but chose to obey. He firmly inserted the needle into Zhao Mengqi's blood vessel and drew out most of the blood.

"Physician, give me the syringe and I'll inject it. You can take Qian Duo's pulse. If you find anything wrong, stop it at any time!"

Next, Zhao Mengqi carefully controlled the speed and slowly sent the blood into Qian Duo's body.

It took a full stick of incense to push the putter to the lowest position. The process went smoothly and no problems occurred.

Dr. Chong kept checking Qian Duo's pulse and kept his spirits high. After nearly a quarter of an hour, he said, "There is nothing wrong. The pulse is stronger!"

Not sure if it was an illusion, but Zhao Mengqi also felt that Qian Duo's face turned a little rosy, "In that case, let's continue and draw the full amount this time."

Zhao Mengqi had to admit that the act of blood transfusion was very much a gamble. After all, there would be many risks in allogeneic blood transfusions in later generations. What's more, now we don't even know what our blood type is, so we are completely relying on deception.

As tube after tube of fresh blood was injected, Qian Duo's condition was visibly improving again, his face became more rosy, and his breathing became smoother and longer.

The three young ladies, Wanwan, looked at Zhao Mengqi with worried eyes filled with admiration and deep love, which were so thick that they couldn't be overcome.

At this time, the Song Dynasty was still there, the Han civilization had not broken down, and Neo-Confucianism had not yet been too deeply poisoned. The status of Han daughters was relatively high, but women were still subordinate to men after all.

A man like this who is willing to use his essence and blood to save a woman, in their eyes, is the most affectionate and affectionate man. There is no more ideal person than this.

Zhao Mengqi never expected that saving people with blood, which was a common act in later generations, would infinitely raise the standards for choosing a mate for his two sisters, causing him to have a headache in the future because of his two sisters' refusal to marry.

When she was about to draw the eleventh tube, Wanwan couldn't help it anymore, "Lang Jun, I can't draw anymore! You gave half of your blood to Qian Duo, what will you do? Your face is pale.

Stop it and change it to mine!"

"Where's the half? At most it's a little more than one-tenth. It doesn't matter. I'm fine. I feel fine. This amount of blood is definitely not enough for Qian Duo. I'd better draw some more."

Zhao Mengqi estimated that his blood volume was only 500 to 600 milliliters. Although it exceeded the standard of blood volume for later generations, it should not be a big problem.

Dr. Chong Taiyi was already a little afraid to take action, so he quickly said, "Your Highness, I don't think it's appropriate to do it anymore. After all, you are also injured, not to mention your hands are starting to get cold now..."

Wanwan stepped forward and grabbed Zhao Mengqi's arm, "Mr. Lang, we agreed before that if it's not enough, I'll take care of you. If you fall down, even if Duo Niang is rescued, she won't be able to do it because of her temperament."

What a stupid thing to do!"

"Fourth brother, you can't pump any more. If it's not enough, Jian Niang can give the blood to Duo Niang." Zhao Jian raised her fist.

Zhao Feng is not lagging behind, "There is still me and I, and Finiang is full of energy!"

"You two sick people should stop just joining in the fun. You two are weak and weak, and you dare to say that you are full of blood. Besides, you two haven't had a blood test, so they are probably not suitable."

Zhao Mengqi scolded the two sisters, thought for a moment, and then asked Imperial Physician Chong, "Imperial Physician, how much more blood do you think Qian Duo needs?"

"This... Judging from the pulse condition, I think I need about half of the previous time." Dr. Chong Tai could only judge based on the physical signs diagnosed.

Under the circumstances at this time, in principle, having a different blood source would bring more risks. It would be best if Zhao Mengqi could provide the blood alone, but others would refuse to let him continue, life or death.
To be continued...
