The next day, Chen Ning went out and came back with a lot of effort to catch a brute pig, and its strength was close to C-level, which made Chen Ning not control the degree of attack in the fight, and finally used the flame to roast it half-cooked (which may also be convenient for the chef to deal with).

After enjoying a delicious pork feast, Chen Ning opened his mouth when the people were about to disperse.

He said lightly: "All the men stay." ”

The voice was not high, but the scavengers did not dare to disobey, Chen Ning's current role was to lead the wanderers of all of them, and they had sworn to obey him.

Chen Ning glanced around and said slowly: "I need you to come up with someone to help me do things, it's very dangerous, and I may die." ”

Everyone looked at each other, Chen Ning didn't ask them much on weekdays, and even brought them meat to provide them with a safe place to live, and now his needs should be met.

But who goes out?

A big man with a square face took the initiative to stand up: "My lord, I'll come." ”

Doing things for the strong, even if there is a risk, the reward can always be beyond imagination, which is the common sense of the last days.

Others are afraid of risks, but he likes profits.

Chen Ning looked at him, his deep eyes making it impossible to figure out his true thoughts.

"Well, you come with me."

The two walked towards the area where Chen Ning was usually absolutely forbidden to scavengers, and the others watched silently behind them, some with tears in their eyes, and some with indifferent expressions.

The two walked near the underground laboratory, Chen Ning took out a remote control from his jacket pocket and pressed it, and an operating table suddenly rose next to "Tengteng", which was the opening device of his laboratory after several transformations.

Crackling operation, Chen Ning pressed the handprint, and the console slowly retracted into the ground, while the other side slowly opened a hole in the ground.

There was a staircase under the cave, and Chen Ning walked down it without saying a word, and the scavenger man followed closely, dumbfounded all the way, he had not seen much of the high-tech era before the end of the world.

Chen Ning changed the way he entered the laboratory, instead walking down from a hole in the ground, and then through the door on the side of the laboratory, so that it didn't have to come up directly from the ground every time it was opened, and the movement was too loud.

After another verification, the two entered the laboratory.

"You take your shirt off."

Chen Ning motioned for the big man to follow, walked to the experimental area, and said with an indifferent expression.

Without saying a word, the big man took off the short coat on his upper body, revealing a strong muscle.

Chen Ning nodded, and when he got to the place, he took a few patches connected to the testing instrument and pasted them on the big man's right arm, and then took out a prepared needle and pricked it.

As the potion in the injection was slowly pushed into the big man's arm, the value on the detection instrument next to him kept beating, and Chen Ning patiently recorded it.

The big man's face was pale, and the beads of sweat the size of soybeans kept sliding down his forehead, but the cold gaze that Chen Ning cast from time to time made him dare not act rashly.

When the tube of needle was injected with the medicine, he completely lost the sensation of his right arm, his face was frightened, and his heart welled up with panic and helplessness.

Chen Ning sorted out the recorded data, finished debugging the instrument, and took a tube of needle and approached him.

"Don't be nervous."

…………

In several sets of experiments, Chen Ning tried several methods to temporarily interrupt the connection between the nerves of Dahan's right arm and the trunk nerves, which helped to reduce the damage to the nerves in the right arm when the right arm was removed in the future.

He records the relevant data and then uses algorithms to find the optimal solution from it.

After connecting to the robotic arm, the artificial nerves in the arm should be seamlessly connected with the nerves of other parts of the body, so that they can be used as they wish, and the transformation is meaningful.

If you cut off the arm with a random knife and install a robotic arm, it will be difficult to achieve seamless docking.

Dahan was a little nervous in his heart, and for the past few hours he had been experiencing the loss of sensation in his right arm, possessing consciousness, and losing consciousness......

Then Chen Ning took him to a clean experimental bench and told him to lie down, he didn't know what was going to happen.

The test bench was activated, and the big man's limbs were bound, and his arms were wide open.

Chen Ning injected another injection into his right arm, and then pinched his watch and waited for a while.

When the time of the effect of the medicine was up, Chen Ning took a thin piece of iron and aimed it at the root of the big man's right arm and cut it hard.

"Brush" the ground, there is no pain, no obstruction, no bleeding, the thin iron piece is over, the big man's right arm is cut off by Qi Gen, the cut surface is smooth and bright, and it is not much different from the mirror.

Not daring to delay, Chen Ning quickly picked up the prepared mechanical arm, which was slightly larger than his original arm, and pressed it on his wound, and the mechanical arm was connected to another instrument through a wire, at this time the instrument data began to jump wildly, and Chen Ning carefully observed and recorded.

After a while, the data displayed by the instrument tended to be stable, Chen Ning rubbed his brows, and the implant was successful.

Of course, this does not mean that the experiment is over, and then he will determine in more detail the operation and performance of the robotic arm after transplantation, whether it is repulsive with the body, and so on.

…………

"Lift."

"Punch."

"Catch."

"Put."

“……”

It's been six days, and Subject One, that is, the big man, the former is his new name, and he spends a period of time every day listening to Chen Ning's instructions, repeating these movements with his right arm to facilitate his recording of control data.

There were several cases of right arm failure or even sudden loss in the middle, but in the end, they were all properly resolved, and of course, Chen Ning's detailed records were indispensable.

After changing arms, although he didn't feel pain or itching in his right arm, he didn't feel much different.

Even he felt that he had earned it, and now his right arm could be opened and there was a storage area where he could put things; The strength is also much greater, his right arm can easily lift a barbell weighing up to 120 kg with one hand, put on a long-sleeved shirt, and it is only slightly thick in appearance and does not affect the rest.

Chen Ning was very satisfied with the effect of this experiment, and at the same time had a new idea in his mind: in order to quickly improve his strength, he would definitely conduct human experiments frequently in the future, and those strengthened ordinary people would be a powerful army if they cultivated loyalty and used them for themselves!

So he renamed Dahan as Subject No. 1, and with No. 1, there will definitely be No. 2 and No. 3 in the future......

Chen Ning temporarily handed over the leadership of the group of scavengers around the laboratory to No. 1, and stayed in the laboratory alone, preparing to start the transformation of his right arm, this plan, he called the "unicorn arm"!

Of course, the mechanical arm he prepared for himself could not be as simple as the No. 1 one, except for the storage function and power increase, there was a GMR-59 laser cannon built into the palm of his right palm, and its energy intensity was probably the same as the ordinary attack of an A-level ability;

There is a power device built into the middle of the arm, which can create momentum to make the right arm drive the whole body to move quickly in a short time;

Five Fingers contains five small recoil-reducing P-6 bullet cannons, which can fire bullets at a speed of 1,900 meters per second, and the attack intensity is comparable to that of a normal B-class ability.

These weapons and devices are all original in the laboratory or he made them himself a few days ago relying on laboratory instruments and materials, and they are of the top level in the old and new worlds.

It can be said that if the Qilin Arm implant is successful, after Chen Ning can use it proficiently, his combat power will really improve by leaps and bounds.

…………

Chen Ning made an intelligent program to automatically operate the implant of his unicorn arm, he didn't worry that someone was watching and controlling his implant process, it was too dangerous.

After the program was completed, it was tried several times and no problems were found, and then Chen Ning compared and calculated the data of the experiment on No. 1 again to ensure that everything was foolproof.
