The 3D printer sprays toner quickly on the formed metal plate armor, and then another robotic arm releases the arc, so that the carbon atoms are instantly oxidized and reduced, combined and arranged according to certain laws, and formed into complex fiber agglomerates.

This is the best buffer layer that Xiangshan can find under these conditions. It can effectively absorb mechanical waves and slow down the damage of mechanical waves to metals and cells. At the same time, the carbon fiber's extraordinary electrical conductivity also provides some electromagnetic resistance to the inner part of the armor.

After this piece of plate armor was well lined, it was thrown away by the magnetic field and fell onto the shelf of a drone. The drone quickly shuttled through the base, transporting the alloy outer armor to the dresser.

The Trainer removed the alloy outer armor and placed it on a torso that was already roughly contoured.

The main part of this viewing has been completed. Only the back part is still empty, and it is necessary for Xiang Shan to complete the replacement of the spine before entering the main body. This outer armor is not a monolithic piece of "iron can". Its back alone is made up of seventy-eight pieces of armor that are independent of each other. Between each two pieces of armor, there is a miniature hydraulic power system as a connection, which guarantees considerable movement ability.

This makes the layout of the outer armor look more like the muscular lines of some kind of non-human creature.

If he wanted to, he could even walk on the ground by the relative movement of these armor plates on his back.

The logic is similar for the side waist and front chest.

Despite this, the strength of these alloy outer armor is only higher than the one used by Xiang Shan before.

Let's just talk about alloy materials, this kind of alloy with laser melting and sound wave controlled crystal growth is far better than the 3D printed material after smelting in the recycling station town.

In terms of overall structure, these outer armors are also more prone to deflection attacks and have stronger resistance.

Watching this armor gradually take shape, Yuki's eyes were hot, and he secretly thought in his heart: "I will also have such a cool prosthesis in the future." ”

This plain white outer armor that hasn't had time to be sprayed with camouflage paint is also really cool.

"Alright, don't look at it. This prosthetic standard is average. Xiang Shan knocked his head: "The inventory of thermal weapons has been completed." Did you go to the shooting range and try your hand at it, as I said? ”

What Xiang Shan said was to ask Yuki to go to the shooting range and try every style of firearm that could be found in Organization Z to find one that he preferred.

Although Xiang Shan has never been a fan of gun lanes, he also admits that gun gun lanes are still very practical in some situations.

For example, in a wild environment with no innocent passers-by, you are surrounded by far more enemies than you are. In this case, if you know how to shoot guns, then your probability of survival will directly increase several times.

In addition, it is also very useful to use the "earth" as a cover to attack the limit outside the horizon.

In Xiang Shan's view, the outer guns, as well as military weapons, are not recommended to be used, but at least they must be able to learn one or two martial arts.

Yuki nodded.

"Which one do you prefer?" Xiang Shan asked.

Yuki uploaded an image.

It was an automatic rifle of an unfamiliar model.

"Rifles? Why? ”

Yuki thought for a moment and said, "Feeling...... Maneuverability is stronger than machine guns, and the need for maintenance is lower than that of sniper rifles. And...... Maybe it's more bullet-saving? ”

"Save bullet ......" Xiang Shan was a little speechless. That doesn't sound like a good idea.

In the gun course, there are a lot of moves developed from "fire suppression". A gunner who thinks about saving bullets will definitely not be a good gunner.

From Xiang Shan's own point of view, if he can use the metal storm to perform the Tiger Shocking Spear Technique, then why stick to the automatic rifle?

"But with our current conditions, maybe the bullets will be more nervous. This is not entirely wrong. Xiang Shan sighed: "After all, most knights are not qualified to kill enemies with bullets. From this point on, it is also a way to gradually master firearms with a higher rate of fire. Okay, practice well. ”

The advent of the auxiliary line system makes it possible for cyber people to not need to ensure that their eyes, muzzles and targets are on the same line when they are at close range, and there are many more martial arts movements allowed. But in any case, it is necessary to familiarize yourself with the performance of firearms.

As long as you know how to assemble a firearm, know how a bullet feels when it is discharged, know whether the gun can hit, etc.,

It's all something that needs to be practiced.

Someone in the old generation summed it up and said that "sharpshooters are fed bullets".

Xiang Shan doesn't plan to let Yuki kill people when his mind is not yet mature, so in the next few years, Yuki won't have too many opportunities to shoot, and at most he will do some auxiliary things.

Then, the Z organization range, which is a good place to provide moving targets, should be put to good use.

After assigning the task to the disciple, Xiang Shan breathed a sigh of relief.

After meeting the little girl, Yuki seemed to see someone who was sympathetic to the same illness - although Xiang Shan knew in his heart that the predicament he and the young girl were in completely different situations, Yuki didn't know. While taking care of the little girl, the teenager seemed to be greatly comforted. He seemed to have come out of the shadow of his mother's tragic death.

"That's a good thing, it looks like the little girl can take a little more with her." Talking to yourself upward.

But before that, the shoddy transformation of that girl also has to be vigilant.

The skull of a Homo sapiens baby is not closed. This is because Homo sapiens has the largest brain-to-body ratio among terrestrial animals, so much so that the huge head is prone to dystocia – the baby has to come out of the mother's womb before the brain is fully developed.

At this time, if the gene expression is wrong and the baby's skull closes prematurely, then the baby will suffer from "microcephaly", and the skull will limit brain development, so that he will only have the IQ of an infant for life.

Of course, Homo sapiens is an animal with an excess of intelligence. Even the level that has not yet developed is stronger than that of most animals.

The brain-computer barrier is a similar problem. The brain-computer barrier also restricts brain growth, so metal clusters of protein shells do not appear until the age of three.

The little girl was implanted with flexible electrodes to capture the brain's bioelectrical activity before the brain-computer barrier was formed.

Flexible electrodes are a very primitive "brain-computer interface". In the twenties of the 21st century, it was widely used in wearable devices and implantable neurological activity monitoring devices.

The bandits had no idea what bad effect this would have on the little girl.

But Xiang Shan doesn't know how to get rid of this thing now. This requires surgery and requires a considerable level of medicine. And to the mountain......

Although he hasn't encountered anything he doesn't understand now, it is a living brain after all, and it belongs to a living child.

Yuki had been badly injured before, but that didn't involve the central nervous system. The baseline human ability to resist injury can ensure the stability of the operation.

But the brain is different.

"If only my memory were still there." Xiang Shan could only sigh in the end.

At this time, the prompt of the clock preset sounds.

It's time for the Reverse Messenger Infuser.

Xiang Shan retrieved the spine, and then walked over to what looked like an operating table. This device is said to be a digital model provided by the Demon Cult and built by the Z organization itself, and is a special equipment for the living part.

Numerous needle-like devices extend from above, immobilize the spine, and drill small holes in each section of the spine with a diameter of microns according to the plan preset by Mukaiyama, and then pierce tiny silk threads into it. There are even thinner wires that help those conductors connect with the nerves.

The process was quick and only took an hour.

The final step is to install the receiver at the end of the fibers of the conductors that are directly connected to the nerve.

The rest is transferred to the maintenance equipment.

Retrofit power unit.

Next, the electrodes are connected to the uppermost end of the cervical spine to stimulate this large nerve, detect the nerve signals in it, and map it to the electronic device that was just attached.

After all this, Xiang Shan once again switched his prosthetic body to remote mode. He then plucked off his head and placed it on the operating table.

The robotic arm lifted his head up again, and a small circular saw approached the end of his cervical fracture.

Soon, the outer bone was peeled away and fell with a snap. Then several other nozzles hang down, spraying dissolved enzymes and saline, and soon, the gray matter layer is peeled off. Quite a few dead glial cells have also been removed.

At this moment, Xiang Shan felt "pain".

It's not "a point" that hurts. He had a hallucination for a moment, as if his physical body was still there, and it was being ravaged by some indescribable means...... It was as if there was a "sense of disease" in his body that was not "pain".

The feeling almost made him give orders to stop the process.

"Hateful ......"

Generally speaking, this kind of surgery involving nerves must be done by someone else. In fact, it is not surprising that the person undergoing the surgery reacts to this direct stimulus.

The next step in this surgery is to reweave and connect the nerve that leads to the mountain fracture with the nerve in the spine.

For the next few minutes, Xiang Shan seemed to have fallen into an illusory realm. Feelings such as "pain, itching, numbness, coldness, and heat" are no longer enough to describe the feeling at the moment.

He wasn't even sure if he was moaning.

"Lean ......"

- After this incident, you must step up the training of your disciples, and strive to give yourself a burst of anesthetic next time you encounter this incident......
