“One bottle of Wusu beer is enough. You can’t drink too much since you have surgery tomorrow.” Liu Zewei laughed.

“Then I’ll take twenty.” Su Yun said.

“…” Liu Zewei was stunned. 20 bottles of life – saving great Wusu? Did he really have to drink so much? Was Su Yun sure she heard him clearly?

The beer girl went to get some beer happily. Zheng Ren asked curiously,””Why is it called the life – stealing great Wusu?”

“There are two reasons.” Su Yun was overjoyed to see da Wusu taking her life.”First and foremost, the main reason is that Huahua gets drunk very quickly after drinking this wine. Furthermore, she has a splitting headache the next day.”

“…” Zheng Ren didn’t understand. What was so good about the wine?

Generally speaking, the wine was soft when it entered the throat, but had a strong aftereffect. Only when one was refreshed the next day after being drunk was it considered good wine.

“Dr. Su is right. One of my friends is out of love, so he dragged me out for a drink. I usually drink a catty of white wine, but after drinking eight bottles of Wusu, I felt like I’ve lost my memory. ” Liu Zewei said with a bitter smile.

“There’s one in the provincial capital?” Su Yun was surprised.

“No, I haven ‘t. It was mailed by a family member of a patient from the southern border. He said that it was produced by an old craftsman and has nothing to do with Jasper’s new factory. ”

“Old Liu, is your friend heartbroken?” However, this was what Xie Yiren was paying attention to.

“Uh … It’s normal for an old tree to have new flowers.” Liu Zewei wanted to drive, but he immediately realized that it was better to behave when talking to boss Zheng’s girlfriend.

“Yiren, don’t interrupt.” Su Yun asked,”can we still contact the patient?” I also feel that there are too many high – grade and impure life – stealing big Wusu wine recently, and it’s not as good as before. ”

“I’m just asking,” Liu Zewei laughed.”Actually, in the past, there were more mellow wines. Otherwise, why would it get on my head the next day?”

“Then why are you still drinking?” Zheng Ren really could not understand what these people were thinking.

“If you don’t drink, you won’t have a life. If you don’t drink, you won’t have friends. If you don’t drink, you’ll be abandoned by the whole world. Boss, did you notice that I was talking about you?” Su Yun said in a serious tone.

Zheng Ren shook his head.

As they were talking, the beer girl came over with a few red bottles of usu.

Su Yun picked up a bottle and placed it upside down on the table.”Boss, take a look at what this is.”

The letters on it should be pinyin Wusu, but when Su Yun turned the wine bottle upside down, it became the English letters nsnm.

“This is …”

“I’ll kill you all!” “Hahaha!” Su Yun laughed.”Boss, don’t you want to try such an arrogant beer?”

“I don’t want to.” Zheng Ren immediately ended the conversation.

“What a boring life. No wonder you don’t have any friends.” Su Yun said,”come, you guys drink some water. We’ll have beer.” Rich boy, the geographical latitude of Wusu is similar to that of Munich, and the taste of beer is similar. Have some. ”

“Don’t drink too much,” Zheng Ren was a little nervous today.

“Boss, you’re different from usual.” Su Yun said in disdain.

“Yes.” Zheng Ren also admitted,”for tomorrow’s surgery, at least one of you or Fugui ‘er needs to help. I’m afraid that there’s something wrong with Dr. Mehal.”

“Director Zhang, you’re here.” Su Yun found an excuse.

“Their cooperation isn’t good enough.” Zheng Ren said,”actually, I don’t think rich people will be able to go up tomorrow. The surgery is more difficult. It’s better if you wear lead clothes and go to the operating table.”

“Boss, that’s not what you said in the beginning.” “Old Liu is here,” Su Yun said.”Why are you looking for me?”

“Old Liu was involved in a tumor intervention. He’s not familiar with the heart.” Zheng Ren muttered to himself, his mind filled with the situation of Dr. Mehar’s surgery tomorrow.

In the system’s training in the operating theater, the auxiliary operations of the experimentals had an unpredictable impact on the surgery.

Moreover, Zheng Ren could predict that the reason why Dr. Mehal wanted to be an assistant, in addition to winning the Nobel Prize and fighting, was more because he wanted to touch the transparent ceiling between the master and the peak.

There would definitely be countless questions during the surgery. Zheng Ren was worried that he would not be able to take care of them all while he had to perform the surgery and answer the questions at the same time.

At this time, he definitely needed the most reliable person to help take care of it.

“Boss, what are you worried about?” Su Yun said in disdain.

“I’m thinking of a Medical Physics formula. Do you think Dr. Mehal will understand what you said to him tomorrow?” Zheng Ren said.

Liu Zewei was stunned.

Medical Physics?

What the hell was that?

Chang Yue had no idea what Zheng Ren was talking about, and it had nothing to do with her. Meanwhile, Xie Yiren had already begun to roast the meat herself. The meat was placed on the iron pan, and a sizzling sound could be heard as the fragrance of the meat permeated the air.

“The law of stickiness?” Su Yun poured herself a cup of wine and drank it. She did not stand on ceremony and drank a cup of the life – threatening great Wusu wine first. She seemed to be enjoying it very much.

“Yes.”

“Boss Zheng, what’s that?” Liu Zewei started to feel guilty.

He originally thought that at the end of the surgery, he would only be able to perform the process by hand. However, he didn’t expect boss Zheng to bring up Medical Physics. What was that?

That bottle of life – threatening big Wusu, which was placed upside down, seemed to be swaying in front of his eyes. “Kill you all …” Liu Zewei felt that he had already been killed.

“When the viscous fluid flows in a laminar flow, the speed of the flow in each layer is different. There was friction between two adjacent layers, which was called internal friction or viscosity. The strength is related to the velocity gradient and the viscous coefficient of the fluid, and it follows Newton’s law of viscosity. ” Zheng Ren explained in a professional manner.

“A guide wire and a catheter have to face a laminar flow of viscous fluid in the blood vessel, and there’s a formula to calculate it. If it was a normal interventional surgery where there were no blood clots when the patient touched the blood wall, the problem would be easily solved. However, it’s best not to touch the coronary arteries during heart surgery. ”

Liu Zewei didn’t understand a single word.

As the leading professor of the Affiliated Hospital of the medical University, his level could be ranked in the top 100 or 200 in the country. He could be considered a well – known professor.

He never thought that there would be a day when he would not be able to understand a single word of an explanation for an interventional surgery that he was good at.

“Old Liu, F= η S (dv/SX).” Su Yun touched the deadly great Wusu with her finger and wrote a formula on the table.

Chang Yue furrowed her brows as she looked at it. It was too dirty. She wondered if he would put his fingers into the beer glass again, if …

“…” Liu Zewei was speechless. What the hell is this?

Medicine was considered a science subject, but it really had nothing to do with physics.

Su Yun saw Liu Zewei’s confused expression and started to explain.

“F is the viscosity force, S is the contact area between the two layers, D/D is the speed gradient in the blood vessel, and the proportion coefficient η is called the viscosity or viscosity coefficient of the fluid, measured in Pa. s or P.

“When you operate on the guide wire, you must at least have this formula in your mind so that you can accurately form a connection between the guide wire and the blood turbulence. The guide wire deviated? If you understood this formula, this wouldn’t have happened. ”

“…” Liu Zewei could only exclaim in shock.

He was speechless. He was already dead.
