Become the city lord from today

Several rookie doctors and the rookie military doctors accompanying the team gathered around. They stared at Liu Feng with their eyes wide open, and bloodshot eyes could be seen in their eyes.

The corners of Liu Feng's eyes twitched, and these people were almost bulging out of their eyes. He opened the rich man's first aid kit, which also contained simple blood test equipment.

Testing blood type is very simple. During his military training, he heard the instructor tell him and tried to find out his own blood type, so he remembered it very clearly.

"People's blood is different. Specifically, it can be divided into type A...cough cough cough...it can be divided into four blood types: type A, type B, type A, B, and type C."

Liu Feng said, but he was not slow in taking out two bottles of blood test reagents from the first aid kit, that is, antiserum, a bottle of blue anti-A (A) serum, and a bottle of yellow anti-B (B) Serum

"This is called a blood test reagent, which is the most important thing in the blood test. There are two types: A and B."

It was the first time for others to hear that there are so many mysteries in human blood. Many people were confused and had never heard of such knowledge.

Especially the rookie doctors, whose lips were trembling with excitement. He took out the parchment, then hurriedly dipped the quill in ink, and quickly recorded it.

When Liu Feng saw this scene, he raised his eyebrows. It seemed that it was time to put some of the paper into the market.

After the doctor wrote it down, Liu Feng continued He took out two pieces of glass from the first aid kit, which made the others breathe a little faster. They thought the glass pieces were crystals.

Liu Feng did not explain, but said calmly,"You don't need this, it's okay." Use ceramic pieces instead."

The doctors then relaxed. If the blood test requires crystals, they would have to sell them by the pound, and they would not be able to afford a piece of crystal.

Liu Feng took out a clean cloth from the first aid kit, and then held a pen on the cloth. Write the words A and B, and then place the glass piece on top of the two words A and B.

"The reason for doing this was to find out Dudley's blood type later."

The rookie doctors were writing furiously, eager to write down Liu Feng's every move.

Liu Feng then dropped the blue anti-A serum on the A-shaped glass slide, and the yellow one on the B-shaped glass slide, and then from the first aid kit. take out a needle

"Then comes the most important step, identifying blood type."

Liu Feng looked at Dudley lying on the bed. His fingers were all dirty. He pricked Dudley's earlobe with a needle and took two drops of blood and put them on the glass slide. After a while, the letter"A" on the glass slide Liu Feng's blood coagulated, and Liu Feng breathed a sigh of relief. It seems that the antiserum on the other side of the earth can also be used in this era.

"The blood on the A crystal chip here has solidified, so Dudley's blood type is A blood type. Now we need to check which of everyone's blood is A blood type, and then give Dudley a blood transfusion to save him."

Liu Feng held up the A-shaped glass piece and said. As for whether there would be complications after blood transfusion, he really didn't know. The rookie doctors stretched their necks and looked at the blood on the two glass pieces. Sure enough, the A-shaped glass piece solidified. , the blood in Party B's glass piece was still in liquid form.

The doubts in Party B's heart disappeared instantly, and his body was shaking with excitement. Those who didn't know it thought he had epilepsy.

"Check mine, use my blood. Niu

Er yelled, and even pulled out his saber, pulled up his sleeves, and gestured with the saber,"Master, how much blood do you want, I will give it to you now.""

"You idiot, put down the knife! Liu Feng shouted angrily,"You also want to bleed too much, and then you can have a blood transfusion, right?""

"Snapped!"

Niu Da slapped Niu Er on the back of the head, which made Liu Feng's eyelids jump. If this continues, Niu Er won't be beaten into a fool, right?

"Brother, why are you so stupid? Didn't you see that you only needed one or two drops of blood just now? Niu Da glared and scolded.

"Uh...excited, a little excited!"Niu Er put away the saber in a coquettish voice.

Dudley had a good relationship with him. When he heard that Dudley could be saved, his head felt hot.

"Come on, come over and help me in a few moments."Liu Feng took out a few more pieces of glass from the first aid kit and handed them to several doctors.

"yes!"

Several doctors took the glass piece tremblingly, followed Liu Feng's example, and wrote the words A and B on the cloth, then dripped antiserum, and then gave Niu Da and the others a blood test.

Liu Feng looked at Niu Da The first test showed that the B-shaped glass plate was solidified, which means that the cow

's blood type is B. And the cow's second blood happens to be type A. If the blood types of the brothers are different, then the blood types of the parents are different. One party may have inherited the father's blood type, and the other party may have inherited the father's blood type. Inherited mother’s blood type

"Master, why don’t both of my blood clots?"Mina's somewhat disappointed voice came from the side.

"oh?"

Liu Feng turned around and saw Mina holding two pieces of glass and looking at him aggrievedly. Is the blood of orcs really different from that of humans?

"Huh? A trace of surprise flashed in Liu Feng's eyes, and he chuckled,"If the blood types on both sides don't coagulate, then it's blood type C, which is the same as mine.""

"real? The same blood as the young master?"Mina stared at Liu Feng with watery blue eyes, looking at Liu Feng expectantly, for fear that she had heard wrongly.

"real!"Liu Feng nodded affirmatively.

"Hee hee hee……"Mina smiled happily. She and the young master have the same blood type. It’s great.

"Lord City Lord, the blood on the crystal pieces on both sides has solidified. Is it blood type A or B?"A doctor asked worriedly

"Yes."

Liu Feng nodded. All four blood types were detected. There are only a few people with blood type A, and Niu Er is one of them.

"Master, draw my blood, draw my blood! Niu Er shouted.

Liu Feng nodded and ordered,"Bring a bed over and raise it a little higher.""

Looking at the anxious Niu Er and the worried Niu Da, he chuckled and said,"Don't worry, it's okay if you lose a little blood, and you will be healthier. Of course, you must be healthy and not anemic."

Suddenly, Liu thought of a certain dark era, an era when bloodletting was used to save lives. No matter what kind of disease you had, even if it was a fracture or trauma, he would give you bloodletting without saying a word. It was called: Cure! It seemed that Bloodletting is a cure-all for all diseases!!!

Liu Feng couldn't help but shudder, and said seriously to several doctors,"If a strong young man loses one pound of blood, it will be life-threatening, so he must Don't think that bloodletting can cure the disease"

"yes!"
