I'm not a genius in the Tang Dynasty

Chapter 316

Wang Zi'an explained for a long time, but His Majesty Li Er didn't understand. In the end, Wang Zi'an had to give up the idea of ​​explaining the blood type to this group of Tang people.

"Anyway, this is our Zhongnanshan secret technique—"

The look of doubt on Li Shimin's face dissipated a lot immediately, the secret art of the fairy family, naturally there will be no such terrible consequences as replacing the blood... Not only Li Shimin, but even Empress Changsun, Li Ke and others have serious expressions on their faces. With such an expression, Wang Zi'an couldn't help being speechless. He knew it would be so easy to solve, why did he try so hard to explain it?
Since it doesn't affect the blood, His Majesty Li Er naturally doesn't care about sacrificing a few lowly prisoners.He made the decision directly and agreed to the blood exchange operation.With His Majesty Li Er's nod, Wang Zi'an began to prepare.

Although other items are readily available, it is not easy to screen for this blood type, especially in this era, some tasks have become more troublesome.Datang didn't have any equipment to test blood type, but fortunately Wang Zi'an knew his blood type, and he planned to use agglutination method to roughly confirm His Majesty Li Er's blood type, looking for someone who could donate blood to His Majesty Li Er.

The so-called agglutination method is to screen through blood type antibodies. Type A blood contains A antigens and B antibodies, B blood contains B antigens and A antibodies, O blood contains no antigens but contains A and B antibodies in plasma, and AB blood contains no antibodies but contains A and B antigens
When the A antigen and the A antibody meet, agglutination reaction occurs, and the red blood cells are adsorbed by the antibody and agglutinated together.A blood clot is produced, which is a thrombus in a blood vessel.In other words, as long as His Majesty Li Er's blood type is not too rare, Wang Zi'an's own blood type can be cross-compared to determine His Majesty Li Er's own blood type and the blood type of the blood donor.Of course, this process will be very cumbersome.

"I hope it's not too rare a blood type—"

Wang Zi'an secretly prayed in his heart, if Li Shimin's blood type was not one of the common blood types, he would have to give up this method of treatment.

For comparison, he first used a golden needle to take a drop of blood from his and Li Shimin's hands, and put them on two pieces of colored glass.When the blood was clear and began to separate, he took blood from his own and His Majesty Li Er's fingers.His own blood dripped on His Majesty Li Er's serum, and His Majesty Li Er's blood dripped on his own serum.

The people in the yard were not aware of Wang Zi'an's operation, and they didn't dare to take a breath. They nervously followed Wang Zi'an and stared at the two drops of serum without blinking, although they didn't know that Wang Zi'an was watching. What the hell is it.

"Fortunately—"

Looking at the reaction of the two drops of blood, Wang Zi'an couldn't help but let out a long sigh of relief, and let go of most of his heart.My own drop of blood reacted and precipitated, but His Majesty Li Er's drop did not respond, so His Majesty Li Er's blood type can basically be determined.Seeing that Wang Zi'an finally relaxed, the group of people couldn't help but heave a sigh of relief.

"Zian, how's the situation?"

"Basically confirmed, type B blood, not too rare—"

His Majesty Li Er's hanging heart finally let go, and there was a trace of regret or joy on his face.Although the blood type is not rare enough to reflect the uniqueness of a great emperor, according to what Zian just said, it should be more ideal.

Knowing the two blood types, the screening will be much more accurate.But at this time, Wang Zi'an realized that he had less glass prepared by others, which affected the progress of the comparison.Who knew that as soon as he said it here, Empress Changsun waved her jade hand, and someone sent a lot of them!

so rich!
Wang Zi'an couldn't help being speechless, this Li Er was crying poor every day, and there were a lot of good things after doing it for a long time.

Although there is a screening method, it is not easy to find a few Type B blood among dozens of people.He had no choice but to let His Majesty Li Er bleed again and again, and then asked people to organize those prisoners to come and test.Probably because of the possible change of blood for His Majesty Li Er, in the gap just now, this group of people were all taken to a hot bath by the servants in the palace, and it was finally not smelly.But even so, these prisoners are all trembling, lest they be chosen by the big devil Wang Zi'an.

Wang Zi'an was busy here, and His Majesty Li Er was not idle, and several news spread quietly.The entire Chang'an City began to change silently around the imperial palace.

The gate of the palace was suddenly locked, and the guards in the palace led by Li Junxian, the general of Zuo Wuwei Zhonglang, and Sun Zhenyun, the newly appointed commander of the Xuanwu gate guards, immediately entered a state of first-level martial law.Qin Qiong, Duke of Ji, who had always been at home, suddenly entered the northern camp and took over the defense of the northern army. Li Jizai, the British Duke, entered the southern camp and took over the control of the southern camp. Cheng Yaojin, the Duke of Su, boarded the camp himself. After entering the Xuanwu Gate, the entire city of Chang'an, loose on the outside and tight on the inside, entered a state of high alert.

The few prime ministers who have been working in Zhongshu Province also rarely did not work, but came to the scene.Apparently, His Majesty Li Er has already made complete preparations to ensure the stability of the situation in the event of an accident during the operation.

Although ordinary people couldn't detect it, those powerful families could smell a hint of storm coming.Many dandies who were wandering on the street were urgently recalled by their families, and locked up at home without saying a word, making these dandies who are used to freedom complain one by one.

Wang Zi'an didn't know that because of such a minor operation, the whole city of Chang'an had become turbulent.Like a hardworking bee, he is carefully comparing the reactions of drops of blood.This matter should not be careless, if one is not careful, His Majesty Li Er may end the game on the spot.

Wang Zi'an was busy until noon before he roughly tested the blood types of dozens of prisoners.However, the result was not very ideal. Out of dozens of people, only three of them could be identified as type B blood. This result made Wang Zi'an speechless.His Majesty Li Er's luck was a little bit too bad, so few people were selected from dozens of people, but this ratio was a bit exaggerated.

"These three people stay, the others go back—"

Wang Zi'an pointed to the three blood type B prisoners with his hand, and said with a frown.

A group of prisoners who were like lambs waiting to be slaughtered suddenly received amnesty, while the three selected ones squatted on the ground with weak legs and feet, and the faint smell of urine came over again. Wang Zi'an felt a little disgusted. He waved his hand.

"Take it down first, wash it well, and have a good meal—"

When Wang Zi'an said this, the hearts of the three prisoners sank to the bottom of the sea, they rolled their eyes and passed out.

Wang Zi'an: "..."

It's just a good meal, as for being so excited?
