Li Su gently straightened Zero's calf, and this slight movement also made Zero tremble slightly.

He first used thick scissors to stick to Zero's calf to cut open the blood-soaked white socks. The blood had begun to scab over, and it felt like it was tearing off a layer of dead skin instead of a white sock. The hideous wound on the knee was exposed, and Li Su applied a layer of iodine tincture, and after waiting for a while, he applied a layer of alcohol to deiodine, meticulously.

"Is the environment here good for surgery?" Chu Zihang asked.

"Originally, it didn't work, but a dust-free place is the best sterile environment." His words had enveloped half of the round table, as well as the surgical instruments and zero smooth knees on it.

"But the light source is a little insufficient." Li Su frowned. "Find some flashlights to help me tie up a shadowless lamp and come out, Lu Ming is not for you to hold it, and the others will go and rest first." Tomorrow will not be easy. ”

The shadowless lamp was quickly ready, and Lu Mingfei stood next to him holding the hexagonal thing, carefully keeping his distance so as not to interfere with Li Su's operation.

The first injection is lidocaine. He injected four doses of the drug into the four corners of the wound, and the drugs formed small bulges under the skin, which slowly flattened after the drugs were absorbed.

This was followed by procaine. Lidocaine lasts for a short time and is easy to produce toxic effects when used too much, so the combination of the two is generally chosen for clinical infiltration anesthesia.

"There's going to be a bit of gore going to follow. If you feel uncomfortable, you can not look at it. Li Su looked up at Lu Mingfei, who was sitting opposite.

"I'm fine." Lu Mingfei shook his head.

"Then I'll get started." Li Su made the first cut.

Many people will arbitrarily think that the doctor is just a carpenter's cutting work, and that the so-called surgery is just the removal of tissue or fixation of artificial substitutes, and there is nothing complicated about it, but in fact, it is not.

For example, removing a metal object embedded in the knee. How to cut the wound minimally? What is the fastest way to take it out and recover quickly? Which organizations should be maintained? And so on and so forth. If it's really like a carpenter picking a nail, secondary damage is inevitable, and that's just one step. In the past, there are disinfection programs for the skin surface and the selection and ratio of anesthetics, and in the future, there are methods for cutting the muscles to cut the fascia and various methods of suturing, which are all knowledge that doctors need to master.

The development of modern technology allows us to replicate disease models in animals for experiments and even computer simulations, but in the past, every kind of knowledge was exchanged for human life, so wound treatment, anti-infection and prognosis have made great progress in the "queue to shoot" period in World War I, including bloodletting therapy and other unscientific things were also verified at that time, and there was no effect.

Two hours later, the operation was completed, and Zero's originally bloody knee was covered with a layer of white gauze. Li Su took off his blood-stained gloves and stuffed them into a garbage bag, connecting bloodied needles and sterile cotton balls. Lu Mingfei put aside the bundle of flashlights as if he had received amnesty, rubbing his sore arm.

Li Su tied the garbage bag in a knot and sealed it, and pointed to the door: "I'll deal with these things, and you can take her to bed when you are rested." ”

Hearing this, Lu Mingfei hurriedly waved his hand. "Why me? I'm a decrepit boy and I don't care about fame, but the little queen cares! ”

"I don't think she cares." Li Su stretched out his hand and snapped his fingers in front of Zero. "What do you think?"

"I don't mind." Zero opens his eyes. Originally, she was under local anesthesia, and she was actually awake all the time.

"Then it's decided." Li Su tied the mouth of the garbage bag tightly and tied it in a knot, picked it up and walked to the door, passing by Lu Mingfei.

The long street at the entrance of Takamagahara is very clean. The black road disappeared without a trace, and the original drizzle stopped, and there was a faint smell of sea in the air, but it felt much lighter than before. The black starless ones are still lit up by the towering signboard of Takamagahara, like the Tower of Babel that reaches to heaven in the Bible story. The waiters were all asleep, and Li Su didn't want to disturb them anymore. He pushed open the school door in the back alley and prepared to go to the vending machine to buy some drinks.

As soon as the door was opened, a green jar flew in. Li Su stretched out his hand to catch it and found that it was a can of oolong tea.

"Let's talk?"

Li Su looked up in the direction where the cans were flying. Fingal was leaning against the wall over there, with a can of beer in his hand.

"Okay." He nodded, and stepped up the stairs to the rooftop.

"What do you want to talk about?" They stood on the rooftop of Takamagahara, on the top of the "Tower of Babel". Li Su propped up on the edge of the rooftop, and not far below was the neon sign of Takamagahara. He looked out at the city's skyline, his forehead gently ruffled by the wind. With a "poof", the pull tab of the can was torn open.

"A lot. What I want to talk about most is your identity. Now, though, doesn't seem to be the time. Fingal leaned next to him and took a large sip of beer.

"And then?" Li Su was unmoved.

"What do you think of tomorrow's negotiations? I mean, what do you think will happen to their brothers? ”

"Let's have a good talk and reconcile. Gen Zhisheng has lost too many friends, and no matter how decisive he is on the surface, he must still subconsciously want to avoid killing the last guy who may be a friend. And Gen Zhinu is no longer Ruri Kazama, he can use makeup and words to get back that strong self, but that soft heart can't control words as sharp as a razor. Tomorrow is not so much a negotiation as two orphans hugging each other for warmth. ”

"Do you really think so? Don't you think...... Forget it, nothing. Fingal cut off the conversation himself, but it was clear that he had not said anything.

It's already the second day, and the horizon is gradually turning white. It is a prelude to the rising of the sun and a celebration of a new day. That monotonous white seems to contain all the hope, so rich that everyone who sees it can share a little from it, and let themselves usher in a beautiful, new day.

"It's like the morning sun that rises every day, and everything will be fine." Li Su held the can high and drank the last sip of oolong tea.

"But it was the sun of a new day, and it didn't belong to yesterday." Fingal muttered quietly, draining the remnants and turning back. Suddenly, he raised his voice: "Go make up for sleep, go make up for sleep!" ”

"Where to make up?" Li Su didn't look back, still staring in the direction the sun was about to rise.

"Why don't you go to the fourth floor? Boss Whale's big bed looks so comfortable, maybe I can borrow the face of my schoolgirl to get some sleep? ”

"It's not just about sleeping, it's about protecting her, right? She is now the person with the lowest combat effectiveness among us, and Lu Mingfei does not count. Li Su suddenly turned around. Tomorrow...... What will happen? ”

"Not sure, I don't know." Fingal disappeared at the end of the stairs.
