Become the city lord from today

Several rookie doctors, as well as the rookie military doctors accompanying the team, all gathered around, their eyes widened, looking straight at Liu Feng, and their eyes could see bloodshots.

The corners of Liu Feng's eyes twitched, these were almost convex, he opened the local luxury version of the first aid box, which also had simple blood test equipment.

The blood type test is very simple, or when he was in military training, listening to the instructor, he tried to test his blood type, so he remembered very clearly.

"Human blood is different, which can be divided into, type A... Ahem... It can be divided into four blood types: type A, type B, and type A and B, and type C. "

Liu Feng said on his lips, but his hands were not slow, and he took out two bottles of blood test reagents from the first aid kit, that is, anti-serum, 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 type, and there are two types: A and B."

For the first time, others heard that human blood has so many mysteries, and many people were confused and had never heard of such knowledge.

Especially those rookie doctors, their excited lips trembled, took out the parchment roll, and then hurriedly took the quill pen to dip ink, quickly recorded.

Seeing this scene, Liu Feng raised his eyebrows, it seemed that it was time to put some of the paper on the market.

After waiting for the doctor to write it down, Liu Feng then took out two glass pieces from the first aid kit, which made the others breathe a little quickly, and they thought the glass pieces were crystals.

Liu Feng didn't explain, and said lightly, "You can do without this, you can also use ceramic pieces instead." "

The doctors relaxed at this time, if the blood test type asked for crystals, they were afraid to sell them by the pound, and they could not afford to buy a piece of crystal.

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 piece on top of the words A and B.

"I did this just to wait to tell what blood type Dudley was."

The rookie doctors were even more eager to write down Liu Feng's every move.

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

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

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

After a short while, the blood on the glass sheet of the word A 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 crystal piece here has coagulated, then Dudley's blood type is A blood type, now you need to check who has a blood type, and then give Dudley blood transfusion to save him."

Liu Feng held up the glass piece of the word A, as for whether there were complications after the blood transfusion, he really didn't know the bottom.

The rookie doctors stretched their necks and looked at the blood on the two glass sheets, and sure enough, the glass pieces on the A word solidified, and the blood of the B glass pieces was still liquid.

At this moment, the little doubt in my heart disappeared instantly, and I was even more excited to swing my body, and I didn't know that I thought that I was crazy.

"Check mine, use my blood."

Niu Er shouted, and also drew his saber, pulled up his sleeves, and gestured with his saber, "Young Master, how much blood you said you want, I will give it to you now." "

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

"Snap!"

Niu Da slapped the back of Niu Er's head, making Liu Feng's eyelids jump, in this way, Niu Er will not be beaten into a fool, right?

"Second brother, what kind of stupidity are you again, didn't you see that it only took one or two drops of blood just now?" Niu scolded with a wide glar.

"Uh... Excited, excited! Niu Er put away his saber in a sneer.

Dudley has a good relationship with him, and when he hears that he can save Dudley, his head is hot.

"Here, you guys come over and help." Liu Feng took out a few more pieces of glass from the first aid kit and handed them to several doctors.

"Yes!"

Several doctors trembled and took the glass piece, followed Liu Feng's appearance, wrote the words A and B on the cloth, then dripped antiserum, and then gave Niu Da and them blood tests.

Liu Feng looked at Niu Da's test, it was solidified on the B-shaped glass sheet, that is, Niu Da was a B blood type.

And Niu Er's just happens to be type A, and the brother's blood type is different, then the parents' blood type is different, one party may inherit the father's blood type, and the other party may inherit the mother's blood type.

"Young Master, why don't my two parts of blood coagulate?" Mina's somewhat lost voice came from the side.

"Oh?"

Liu Feng turned his head and saw Mina pinching two pieces of glass, looking at him aggrievedly, could it be that the blood of orcs is really different from that of the Terrans?

"Huh?" A hint of surprise flashed in Liu Feng's eyes, and he chuckled, "The blood types on both sides are not coagulated, that is the blood type of propylene Oh, 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 misheard.

"Really!" Liu Feng nodded affirmatively.

"Hee-hee-hee..." Mina smiled happily, she was the same blood type as the young master, it was really good.

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

"Yes."

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

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

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

Looking at Niu Er, who was rushing and rushing, and Niu Da, who showed concern on his face, he chuckled, "Don't worry, it's okay for people to lose a little blood, and they will be healthier, of course, they must be healthy and not anemic." "

Suddenly, Liu thought of a certain dark era, the era of saving people by bloodletting therapy, no matter what kind of disease you are, even if it is a fracture, trauma, don't say a word to give you a knife to bleed, the name is good: cure the disease!

As if bloodletting therapy is a cure for all diseases!!

Liu Feng couldn't help but shiver, facing several doctors, and said seriously, "If a strong young man loses a pound of blood in one sex, it will endanger his life, so don't think that bloodletting can save the disease." "

"Yes!"
