"Hmm......" Chen Ning woke up from his misty state.

He was lying on a large bed, regaining some energy, but the scars all over his body were still aching, especially in his left abdomen, where the herbs had lost their effect, and he felt that large areas of skin and muscles were losing sensation.

"Are you awake?"

An old voice sounded in his ears, and when he looked sideways, it was a kind old man, as if he was a little familiar.

"Hmm...... Where am I? ”

"You fainted outside the gathering place, and I brought you back. Because a little curious, um, that thing? He pointed to Chen Ning's unicorn arm.

"Thank you...... But, can you do me a little more favor? "It's a bit abrupt, but it can't be helped, the injury continues to deteriorate, and it can't be delayed for a moment, if it is corroded to the digestive tract, it will be really troublesome.

"You mean, your wounds?" The old man walked over and lifted Chen Ning's clothes, exposing the wrinkled, rotting flesh of his abdomen to the air.

"Hmmm......"

"I'll try."

As he spoke, the old man reflexively went to the next room, and a minute later pushed a small cart with all kinds of medicines and scalpels on it.

"I was a doctor before the end of the world, but I need my consent to perform surgery." He winked at Chen Ning and smiled gently.

"Hmm...... If you can, I want you to do what I say," Chen Ning was more convinced of his own level, and he raised his right arm: "Afterwards, you will get the method of making this arm of mine, and the method of transformation." ”

The old man shrugged his shoulders, and he could see the self-confidence, or rather conceit, and wariness of the cold, bald young man in front of him.

"Whatever, but if you're too unprofessional, I'll stop, I'm a doctor."

"No anesthesia."

The old man had already picked up the prepared anesthetic injection, and when he heard this, he was stunned and put it back again.

"Flat-headed hook, 5 cm below the lumbosacral angle, pull."

The old man did as he was told.

"Medium round knife, 4 cm above the pubic symphysis, cut."

"Small disc knife, ...... within the boundaries of the real and false pelvis"

“......”

As the operation deepened, fine cold sweat broke out on the old man's forehead, this was a delicate job after all, and his A-level strength did not work here.

The young man in front of him was so shocking that he didn't see the wound, he endured the sharp pain of the knife cut, and only relied on his own feelings to command others to drop the knife accurately, and the knife was not bad at all, and even the old man himself couldn't think of it and couldn't do it in some places.

After this operation, he even felt that his surgical skills had improved.

"If you take the medicine...... Well, Antène has it, right? After removing the corroded rotten flesh, dead flesh and susceptible parts, Chen Ning gritted his teeth and asked lightly.

Anteine is a top anti-inflammatory drug before the end of the world.

"Yes, yes." The old man wiped a handful of sweat from his forehead, put the surgical instruments on the cart, and then took a bottle of medicine from the cart.

Open the mouth of the bottle and put in a few medical cotton swabs to soak.

"The part where the knife was used just now, let's go up."

"Well, it hurts a little...... Bear with me. ”

"Don't worry, they all came here just now."

............

This may be the biggest crisis he has ever experienced, Chen Ning thought, in the final analysis, the reason is not only not enough strength, but also not enough caution.

Although he clearly knew that Hei Shuiba was very strong, and he also had a combat power that surpassed B+ level in the growth period, and his Qilin arm could not help him so much now, he still didn't choose to run away immediately.

Thinking that it was the Lian Zhan Lianjie since he came here that gave him the idea of daring to go up and fight a dozen of anything, he was a little floating.

After the operation, Chen Ning's lips were pale, but he felt much better. As long as Heishuiba's poisonous wounds can be resolved, the other injuries on his body are not important.

"Rest for a while, and I'll talk to you again in the evening."

"Hmm."

The old man threw away the used cotton swabs and pushed the cart away, as the supreme leader of Tongbei, he had to deal with a lot of work every day.

Chen Ning finally woke up after three hours of sleep, and the old man was sitting on the edge of his bed, holding a pair of glasses and looking at the briefing in his hand.

His strength is very strong, maybe to A or A-level, this is Chen Ning's first judgment on the old man's strength after ensuring his own safety.

He couldn't detect the existence of α particles in the other party's body at all, but he could feel the other party's condensed momentum.

The old man knew that Chen Ning was awake, but he still waited until he finished reading the briefing before putting down the glasses on the bridge of his nose, then putting away the briefing and rubbing his eyes.

"Tell me, young man, where you come from? And how much do you pay? ”

"My name is Cheng Xin...... Well...... A wanderer, the words of a mechanical arm...... Bring me pen and paper, and I'll write it down for you. ”

Chen Ning used the name of his previous life and used a fake identity, facing this suspected A-level powerhouse that he couldn't shake for the time being, it was right to keep a hand.

The old man got up and went to the side to get a pen and paper and handed it to him, and Chen Ning also endured the pain in his abdomen and sat up from the bed to take it.

"You're a B-rank at a young age, and you know so much, just a wanderer?"

Chen Ning buried his head in writing and drawing on the paper: "Hmm...... I've got some pre-apocalyptic relics, labs, things like that......"

There was no fluctuation in his heart, even if this old man had bad intentions and asked him to dedicate the laboratory, he would be able to find seventeen or eighteen good places with suitable conditions in minutes, even if it was an A-level powerhouse, he would die without a place to bury.

The old man smiled: "Don't worry I'm interested in your secrets, I've lived a handful of years, and the ability is a thing, whether life or death is brought or not." But I think you seem to have experienced, I don't know what it's like to be outside Tongbei? ”

Chen Ning continued to write the production methods and drawings of the unicorn arm: "You are so strong, haven't you ever gone out?" ”

The old man shook his head helplessly: "At the beginning of the end of the world, I evolved my ability and led a large number of people to establish Tongbei, during which I don't know how many waves of xenomorphs and wanderers I have repelled, how dare I leave easily?" That is, after the matter is dealt with every day, you can walk around the same north. ”

The pen in Chen Ning's hand paused, and he was in awe of him in his heart.

As the strongest person in a gathering place, he did not choose to be a parasite like a crane, at most symbolically acting when the gathering place was in crisis, but chose to use his authority to manage the entire gathering place more conveniently and efficiently, and work for everyone.

It is with them that humanity can finally usher in the new world.

"Outside Tongbei, there are many more dangerous and powerful alien species, there are many larger-scale human settlements, there are many legacies and gifts left to us by the past life, and there are many wanderers who are insatiable and kill their compatriots...... Probably so. ”

"I really want to see other human gathering places......"

Maybe you'll see it soon, Chen Ning thought to himself.

The old man took a closer look at what Chen Ning had written, and touched his unicorn arm: "I saw this thing before the end of the world, and I was very impressed, and the technology to make it is very useful whether it is put in production or military. ”

Chen Ning nodded, after getting the gene topology instrument back, Qinghua's industrial foundation should have been built, and he could also start to apply human mechanical technology on a large scale.
