Starting Today, I'll Work as a City Lord.

Liu Feng took out a clean cloth from the first aid kit, then took a pen and wrote the words A and B on the cloth, and then put the glass sheet on the words A and B.

"I'm doing it this way so I can tell what blood type Dudley is."

The rookie doctors are even more eager to write, and can't wait to write down Liu Feng's every move.

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

"Then is the most important step, distinguishing blood types."

Liu Feng looked at Dudley lying on the bed, his fingers were dirty, he stabbed Dudley's earlobe with a needle, and took two drops of blood and put it on the glass.

After a while, the blood on the nail plate glass coagulated.

"The blood on the crystal plate with letter A has coagulated, so Dudley's blood type is blood type A. Now we need to check whose blood is blood type A, and then give Dudley a blood transfusion to save him."

Holding up the A-shaped glass slide, Liu Feng said, as for whether there are complications after blood transfusion, he really has no idea.

The rookie doctors even stretched their necks and looked at the blood on the two pieces of glass. Sure enough, the glass on letter A was solidified, and the blood on Party B's glass was still liquid.

At this moment, the little doubts in my heart disappeared in an instant, and the body swayed with excitement, and those who didn't know it thought they were going crazy.

"Check mine, use my blood."

Niu Er shouted, pulled out his saber, pulled up his sleeves, and gestured with the saber, "Master, how much blood do you want, I'll 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 the back of Niu Er's head with a slap, and Liu Feng's eyelids jumped. If this goes on, Niu Er won't be beaten into a fool, right?

"Second child, what are you doing stupid, didn't you see that you only needed a drop or two of blood just now?" Niu reprimanded with wide-eyed eyes.

"Uh... excited, a little excited!" Niu Er put away the saber embarrassedly.

Dudley had a good relationship with him, and when he heard that Dudley could be saved, his head became hot.

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

"Yes!"

A few doctors took the glass piece tremblingly, followed Liu Feng's example, wrote the words A and B on the cloth, then dropped antiserum, and then tested Niu Da and the others.

Liu Feng looked at Niu Da's test, and it was the coagulation on the letter B glass, that is, Niu Da was blood type B.

And Niu Er happened to be type A, and the brothers' blood types are different, so the parents' blood types are different, one may inherit the father's blood type, and the other may inherit the mother's blood type.

"Master, why didn't my two bloods coagulate?" Mina's somewhat lost voice came from the side.

"Oh?"

Liu Feng turned his head and saw that Mina was holding two pieces of glass, looking at him aggrievedly. Is the blood of the orcs really different from that of the human race?

"Huh?" A hint of surprise flashed in Liu Feng's eyes, and he chuckled, "If the blood types on both sides are not coagulated, that is blood type C, the same as mine."

"Really? The same blood as the young master?" Mina stared at Shui Lingling's blue eyes and looked at Liu Feng expectantly, for fear that she had heard it wrong.

"Really!" Liu Feng nodded affirmatively.

"Hee hee hee..." Mina smiled happily, she was the same blood type as the young master, which was really nice.

"Lord City Lord, the blood on the crystal pieces on both sides has coagulated, is it blood type A and B?" a doctor asked worriedly.

"Yes."

Liu Feng nodded, all four blood types were checked out, and there were only a few people with blood type A, and Niu Er was one of them.

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

Liu Feng nodded and instructed, "Bring a bed and make it a little higher."

Looking at the rushing Niu Er, and the worried Niu Da, he chuckled, "Don't worry, it's okay for people to lose a little blood, and they will be healthier. Of course, they need to be healthy and not anemic."

Suddenly, Liu thought of a certain dark era, the era when bloodletting was used to save people. No matter what kind of illness you have, even if it is a broken bone or trauma, you will be bleeded without a word, and the famous name is: cure!

As if bloodletting is the cure for all ailments! ! !

Liu Feng couldn't help shivering, facing several doctors, said solemnly, "If a strong young man loses a pound of blood at one time, it will endanger his life, so don't think that bloodletting can save the disease."

"Yes!"

Chapter 0105 sew wounds like sewing clothes.

Several doctors nodded ignorantly, and wrote down Liu Feng's statement that the young man lost a pound of blood, which was life-threatening, and marked it with the words of the city owner.

In the future, if they are teaching apprentices, they will say this, "The Lord of the City said that once a person loses a pound of blood, his life will be in danger, so you must remember that the Lord of the City was very strict at the beginning... …”

Liu Feng didn't know the thoughts of several people. If he knew, he would be happier. This is what he wanted.

Niu Er consciously lay on the raised bed and stretched out his dirty arms. Not to mention, he was a little nervous. He would be the first case of blood transfusion in this era.

"Use this alcohol to clean the arms of both of them."

Looking at the dirty arms of the two, Liu Feng took out two bottles of disinfectant alcohol from the first aid kit and gave them to the doctor. He didn't want to be rescued, but died of bacterial infection in the end.

He decided to get out the high alcohol, especially alcohol, which is often used to clean wounds and disinfect and sterilize. It is a very important material.

And wine can be bought at a good price. Those nobles like it very much. As long as the packaging is good, I am afraid that those big nobles will spend dozens of gold coins to buy it.
