Took 5 anthropomorphic bodies from the anthropomorphic preservation room.

Li Qingye came to an exclusive experimental area that had been prepared for a long time, and more than a dozen scientific research assistants were ready.

"Let's get started!"

With his order, the scientific assistants began to get busy.

They lifted an anthropomorphic human body out of the life support chamber, inserted various life-support devices, and inserted a specialized syringe needle into the human vein.

Immediately after that, a cylindrical container was taken out of a biological safe, about the size of a large thermos flask.

Attach the container to the syringe.

When the start switch is pressed, the special liquid in the container is injected into the anthropomorphic body little by little.

Another scientific assistant looked at the feedback data from the artificial brain.

A large number of free cells in the special solution enter the whole body of the anthropomorphic body with the veins.

About an hour or so passed.

"Chairman, cartilage tissue is starting to form."

Li Qingye turned his chair and looked at the holographic body structure model formed by the scanning device, and a layer of cartilage under the dermal tissue on the surface of the anthropomorphic human body began to form.

These cartilage tissues are distributed in fibrous structures that begin to grow under the dermal tissue on the body surface and then spread to the muscles and internal organs.

"Reported that the test subjects are gaining weight......"

"Report, Subject ...... Height"

As chondrocytes continue to build cartilage tissue in the subject's body, the subject's body weight increases little by little, and his height and body shape also expand a little bit.

Until 36 hours later.

Chondrocytes completed the construction of the endoskeleton, and the body weight increased by 18.3%, the height increased by 3.2 cm, and the body contour was much thicker.

In short, it's getting stronger.

At this time, in the scanned holographic body model in front of Li Qingye's eyes, the white lines represent cartilage tissue, and these cartilage tissues have densely covered the entire body of the experimental subject.

"Inject neural networks to build cells."

"Yes."

These cartilage tissues are fused with muscles, blood vessels, bones, and internal organs to form an artificial skeleton that is embedded into the human body.

And this artificial bone system is called "endoskeleton".

Endoskeleton, as the name suggests, is the bone in the body, which is used to distinguish the exoskeleton from the autologous skeleton.

The reason why Li Qingye developed the endoskeleton is to strengthen the human body, which is actually one of the components of bio-based nails.

The old version of bio-based nails is mainly through a biological exoskeleton covering the body surface, plus various functional symbiotic insects, symbiotic bacteria and biochips in the body.

In application practice, although the old version of bio-based armor has very good functions in all aspects, there are still some shortcomings.

For example, if the body is hit violently, it will also cause coma, internal organs damaged, broken bones, ruptured blood vessels, and even death.

Although Homo sapiens' security forces are now rarely in close contact with the enemy, it does not mean that this problem can be ignored.

Because bio-based armor has another big application field - spacesuits.

Especially in the ascent phase of the launch vehicle, or in the orbital airborne phase, overloading is basically a common occurrence.

At present, the Medan Space Group, a subsidiary of Homo sapiens, produces an ape-eating launch vehicle with a maximum overload of 4.8g in the atmospheric stage, which is nothing for astronauts equipped with bio-based armor.

But another subsidiary, Dandelion Aerospace Group's aerospace airship and air transport aircraft, has a maximum overload of 6.7 g in the rising phase of the atmosphere, and in the event of an emergency suborbital airborne, the maximum overload can even reach 12.5 g.

If the overload exceeds 12g, even with bio-based armor, astronauts may still fall into coma, black vision, red vision, and induce cardiovascular disease.

Through a series of practical application feedback data, various aerospace subsidiaries have found that the current bio-based armor has certain limitations.

Its limitation is that when the overload breaks through the threshold, all organs of the human body will be compressed, which will lead to dyspnea and abnormal blood circulation.

To solve this problem, the endoskeletal system came into being.

The endoskeletal system, which is composed of a special group of cartilage tissue, is similar to the corpora cavernosa in its own nanostructure, and after it is formed in the body, it stores a certain amount of normal saline.

Once encountering a sudden external force, the soft endoskeleton will instantly harden and tense the body.

The stronger the external force, the stiffer the endoskeleton becomes, similar to the force pattern of non-Newtonian fluids.

However, there is also a limit to the pressure of the endoskeleton, if the instantaneous overload exceeds 30g, even if there is an endoskeleton system, the body will be squeezed by the overload.

For this point, Li Qingye and a group of researchers did not report too high expectations when designing the endoskeleton system, and the safety overload below 25G can be realized, which is the greatest value of this system.

Of course, the endoskeleton system is not only used for anti-load.

In fact, the endoskeleton system has many functions, including load resistance, bulletproof resistance, impact resistance, heavy pressure resistance, and improved exercise ability.

With the cooperation of biochips, it is possible to lift a weight of 500 kg without an exoskeleton, jump from a height of 10 meters, and the body can be intact.

At the same time, with the endoskeleton system, after equipping the exoskeleton of bio-based armor, the coordination between the body and the exoskeleton will be more perfect.

But it's all a case of supercomputing simulations.

Actually, experiments are now underway.

Injecting neural network building cells into cartilage tissue is another key point of the endoskeletal system, that is, so that cartilage tissue can be completely integrated with biochips.

】

Only by completing the neural network connection can the cartilage tissue be finely controlled.

Li Qingye and his scientific assistants, looking at the feedback data of the artificial brain, the cartilage tissue inside the simulated human body is connected to the biochip little by little through the neural network to build cells.

The process took 8 hours.

When the last part of the cartilage tissue is connected to the neural network to build cells, the endoskeletal system inside the anthropomorphic human body is officially implanted.

"Test blood regulation."

“ok。”

The part of cartilage tissue that surrounds the blood vessel is successfully reduced by contraction and squeezing, and even directly intercepted the blood supply to some parts.

Then artificial cardiopulmonary resuscitation is performed directly in the body, and the endoskeletal system can directly squeeze the heart, and there is no need for external compressions.

The next step is to test artificially assisted intestinal peristalsis, varicose vein repair, respiratory foreign body discharge, and assisted breathing.

Among them, the endoskeletal system implanted in the alveoli, this part is the most special, because this part of the endoskeleton can also have another effect, that is, to block the direct contact of external fluids into the alveoli.

At the same time, the upper respiratory tract is implanted with a special symbiotic fungus, which can penetrate the hyphae into the alveoli, then absorb oxygen from the fluid, transport oxygen to the alveoli, and expel the carbon dioxide released by the alveoli.

That is, humans at this time can breathe directly underwater.

In order to solve the problem of fluid exchange caused by underwater breathing, the endoskeletal system can temporarily open up the upper respiratory tract and esophagus, and at the same time temporarily close the connection between the esophagus and the stomach, so that oxygenated liquid enters the respiratory tract and carbon dioxide-containing liquid is spit out from the esophagus.

Of course, if this special underwater breathing mode is in a natural water body, the body's activity function will be greatly reduced, because the oxygen content of the natural water body is too low, and the oxygen supply will be insufficient.

Without the assistance of the endoskeletal system, underwater breathing and even swimming cannot be done, and can only float underwater.
