The serum identification method needs to isolate the serum of the two blood types A and B in advance, and then drip the blood of the subjects separately to observe the changes in different reactions, and the four basic blood types A, B, AB, and O can be identified, which not only has a low error rate, but also is simple and fast.

In fact, the isolation of serum is not complicated, it also belongs to the category of those who are difficult will not, and most of the civilian technology in the world is like this, as long as you know the principle, you will immediately realize that there is no need for too strict objective conditions to support, and there are very few real high-precision technologies.

Although Zhou Yanqi did not know the series of theoretical bases and meanings behind the blood type, he knew the steps, dripped blood into the serum, observed the characteristics, and seemed not in a hurry, but he was facing away from everyone, and those who did not know did not know what he was doing, so he could only guess randomly.

It didn't take long for Zhou Yanqi to turn around and say to Jean, "Jean, go and collect two thousand milliliters of type A blood from the workers outside." ”

"Okay!" Jean and Kate took the serum, test tube and syringe and walked out, taking advantage of this time, Lin Youniang also prepared the anesthetic and injected Pied into it.

For Pied's disease, Wang Feng is really careful to treat, and strive to be foolproof, so even the common use of chloroform in Europe is useless, this kind of thing not only has great side effects, the dose is small and can not achieve the effect of anesthesia, and the dose is large and will be fatal, so a new type of anesthetic made of hops as the main material and then added with its own anesthetic.

The brown fluid injected into Pied's body, as well as a skin test and penicillin injections, made the four onlookers very incomprehensible. can't help but talk about it, and some people even implicitly ridicule. However, Wang Feng didn't pay attention to it and waited patiently.

Gradually. Pied's eyelids closed and he snored heavily, and Jean and Kate also took out several large bags of blood, and immediately transfused Pied without Wang Feng's instructions.

Wang Feng then took the scalpel and gestured on Pied's chest, supplemented by finger massage to input dark energy, trying to seal the blood veins, so as not to cause blood to gush like a spring.

Pretty much after. Brush! Wang Feng suddenly flashed with a knife light, and slashed his entire right chest!

The four professors were stunned for a moment, others did the operation, they all used the knife with extreme care, but this Bush doctor, the technique was so fast that he couldn't see clearly, this kind of cutting method was simply unheard of, and then, something even more incredible happened. Although Pied was also bleeding, the amount of bleeding was far less than expected, intuitively speaking, it was not a squirt. It's oozing out!

"Oh! My God, what's going on? A professor asked him left and right, but no one could answer him.

"Please don't make a noise!" Wang Feng glared at him. He put his hand in and carefully pinched it on the lobes of his lungs. He wants to feel the position of the tuberculous ball, in general. The tuberculosis ball is an irregular round ball with a diameter of about three centimeters, which is also the root cause of pulmonary tuberculosis, and the treatment of pulmonary tuberculosis can never be cured without removing the tuberculosis ball.

The position of the tuberculosis ball is not fixed, it may be the left lung, it may be the right lung, and the position can be determined by B-ultrasound in modern times, but Wang Feng can only choose one side at random like flipping a coin.

I have to say that Pied was quite unlucky, he was stabbed in vain, and after touching it for a while, Wang Feng showed disappointment, shook his head and said: "You all come over to see, normal people's lungs are pink, but Pied's lungs are gray and black, this is the consequence of long-term smoking, it will damage your body, cause many lung diseases, and even die, the danger of smoking I have already said, I hope that you smokers can be vigilant, be responsible for yourself and your family, and quit smoking." ”

"Yes, yes!" Several party members who helped to help responded, but everyone could see that these people were perfunctory.

After all, in that era, no one could realize the danger of tobacco, or even if they realized that although tobacco was not as dangerous as drugs, it was more difficult to quit than drugs, and almost all ex-smokers relied on perseverance to endure, rather than really getting rid of their dependence on tobacco mentally.

But then again, Wang Feng's main purpose was to show Zhou Yanqi and Lin Youniang that whether the British smoke or not had much to do with him, he just needed to control Chinese smokers as much as possible, so he didn't say more, and called back: "Obama, sew your chest on behalf of Mr. Pied." ”

"Oh!" As Wang Feng's only disciple, and as a check and balance to the national bourgeoisie represented by Sheng Xuanhuai in the future, Zhou Yanqi is not only a martial artist, but also proficient in all aspects.

After answering the call, Zhou Yanqi took the needle and thread, and it took fifteen minutes to carefully suture the incision.

Wang Feng picked up the knife for the second time, brushed it a few times, cut his left chest, stretched out his hand and groped for a while, and in the upper half of the lung, he felt a round ball, which was obviously a tuberculosis ball.

Tuberculosis ball is similar to tumor in appearance, but it is not a tumor, but a special form of pulmonary tuberculosis, generally not cancerous, it is evolved from secondary tuberculosis foci in the lungs, when the number of tuberculosis bacteria is small, the virulence is low, the body is weak allergic reaction, and the immunity is strong, the tuberculous inflammation is quickly wrapped by fibrous tissue after the formation of the tuberculous ball, which is not contagious, and has no effect on the patient himself, but once it recurs and is re-infected, the contagiousness will be extremely strong, and Pied belongs to this situation, even if Wang Feng has a dark energy, don't dare to be hasty, in case you get wet, even if you don't have a seizure, but if you infect ordinary people such as Angelina, it's too late to regret it.

After thinking about it, Wang Feng ordered: "Bring a coal stove in!" ”

"Yes!" A party member walked away quickly, and after a while, he brought in a coal stove.

This time, Wang Feng put on gloves, carefully picked open the lung lobes, rotated the knife, cut the tuberculosis ball away from the lung tissue, picked it on the tip of the knife, and then threw it into the coal stove with the scalpel!

"Zila, zila!" The flames engulfed the blood-soaked tubercle balls, emitting bursts of black smoke with a strong fishy smell that could be smelled even with a mask.

Sharpe was shocked in his heart, as a professor of medical school, even if he was limited by his knowledge, he could smell that this was not the scorching smell of burning flesh at all, but the unique smell of burning rotten poisonous substances, out of professional nature, he wanted to ask Wang Feng what was taken out of Pied's body, but when he saw Wang Feng's face that was written on him, he had to forcibly suppress this thought.

He is a member of London's high society, and he can't hold his face when he chokes on two sentences, and he can't help but secretly think of other ways.

Wang Feng seemed to see through Schaelpe's anxiety, only glanced at it, then took some ointment, smeared it on the wound in Pied's lung, and then beckoned Zhou Yanqi to sew Pied's left chest shut, and then called Monroe in. (To be continued......)
