SECURITY means 'security' and 'protection', and it also refers to engaging in security-related work.

And put it here, it refers to the security personnel, that is, the security guards.

In Nakasu, many people think that security is a very low profession, but in foreign countries, they do not think so.

Compared to mercenaries, this job is significantly more secure and safer.

Well, at least for the time being......

However, even if we still have to fight and kill in the future, the salary is real after all.

You must know that even the Middle East, which has the highest mortality rate in the whole federation, is far from the price given by Chen Chen, and the common price of this group of people was only between 8,000 and 12,000 US dollars.

After subduing this group of outlaws with money, the rest of the matter is much easier.

Before signing a contract with this group, they were like a time bomb that would explode at the research center at any time.

However, the more this kind of profession is close to the primitive, the more it tends to the law of the jungle, and when Chen Chen really becomes the employer of this group of people, this group of people can become a sharp weapon in Chen Chen's hands.

After all, not everyone can offer them a job with a monthly salary of $30,000, and for the sake of this salary, they will not allow anyone to hurt Chen Chen.

Of these thirty people, Chen Chen divided them into five teams, each team of six people, the captain was chosen by themselves, and Cheng Chao was the temporary captain.

Let a Middle-earth person act as a commander, of course, this group of people will not be convinced, but if they are not convinced, they can be physically convinced, and Cheng Chao, who wears a GS combat uniform, does have a crushing advantage in hand-to-hand combat.

gave Cheng Chao such a big advantage, if he still couldn't manage this team, then Chen Chen couldn't help anything.

In order to better manage this group of war animals, Chen Chen simply built a training camp on the open space outside the research center, and at the same time prepared to change the second basement floor of the laboratory building into an actual combat shooting range.

There's even a week-long vacation each month to give the energetic beasts time to go to the bars of Walvis Bay to vent.

These thirty people, together with Cheng Chao's team, Chen Chen formed a security department called "Black Security Service", which translates to "Black Security Service Department".

At the same time, I don't know whether it was intentional or unintentional, Chen Chen also incorporated the fifteen local security guards into this department, and at the same time formulated a strict departmental code.

For example, we get up at six o'clock every day for training, and there must be two teams patrolling at night.

It's going to be interesting to think about the rest of the year.

Without paying too much attention to this matter, Chen Chen quickly turned his attention to the first experimental villagers in Gorob Village.

After more than ten days of cultivation, the cloned embryos of the old villagers had successfully developed into embryo sac form, and then the embryonic stem cells were extracted by Chen Chen's assistant, and the next step of proliferation and cultivation was carried out.

However, among the old men, there were three patients with liver cirrhosis and two pneumoconiosis patients who used to be miners, and these five Chen Chen had an extra cloned embryo.

Of the five extra embryos, Chen Chen did not extract embryonic stem cells, but kept them.

After all, you must know that all of Chen Chen's technologies are developed to prolong human lifespan, and if you want to extend human lifespan, in addition to replacing stem cells, there is actually a more direct way, that is, organ transplantation.

Human heart, lungs, liver, kidneys and other vital organs can be transplanted, strictly speaking, any lesions of such organs can be solved by transplantation, but why do tens or even hundreds of thousands of people still die every year because of diseases of such organs?

That's the rarity of these organs, not only rare, but also the problem of matching and rejection.

But what if you could clone your own organs?

If Chen Chen wants to rely on life-enhancing technology to attract a wave of sponsorship, then in addition to aging reversal treatment technology, maybe he can also add a business......

In fact, Chen Chen had already thought of this idea and had already begun to implement it.

At this time, he came to a tissue engineering laboratory on the fifth floor of the experimental building.

In the laboratory, several researchers are concentrating on their work, and these are the newcomers invited by Chen Chen.

At the beginning, Chen Chen invited 300 young talents with potential in the biological world, and in the end, 200 of these people stayed, most of them became assistants to the group of professors, and the rest became scientific researchers who served Chen Chen.

“Boss！”

"Boss!"

Chen Chen nodded, he looked at the instrument in front of everyone, "Is the preparation completed?" ”

"It's done, we've prepared ten pieces of artificial endometrium."

The blond youth at the head turned and replied, as he spoke, leading the way to a transparent fish tank.

It is said to be a fish tank, but it is actually a kind of incubator similar to the shape of a fish tank, with transparent materials on all sides, except that the top is sealed by a metal lid, and two rubber hoses, one black and one white, extend into the tank from the top.

From Chen Chen's position, the two hoses were connected to a palm-sized, visceral-like biological tissue in the incubator.

The creature tissue was faintly triangular in shape, like a ......

"This is the artificial endometrium that we have prepared."

The blonde youth looked at the lump of meat with an intoxicated expression, as if he was looking at a work of art, "According to the 'endometrial in vitro 3D modeling', we first use the biodegradable 'polylactic acid hydroxyacetic acid copolymer (PLGA)' to create a human body shape that can accommodate the fetus."

"Then the 'endometrial stromal cells' and 'epithelial cells' are planted on the upper and lower sides of the PLGA and provide sufficient nutrients, and after about 14 days, the cells begin to fuse into patches, grow in a compound layer, and form a guided three-dimensional structure."

Chen Chen nodded when he heard this, this technology is actually not difficult, after all, it is not the black technology of "generating complete human organs", it is just an inner layer layer, and even as early as 20 years ago, Professor Liu Hongqing of Cornell University in North America had already realized this operation.

The only difficulty with this technology is how to generate blood vessels that can be used to deliver nutrients like real human tissue.

"So, can artificial vascular networks be chimerated?" Chen Chen asked again.

"Yes, we're using a hybrid proliferation approach."

The blonde young man pointed to the two pipes, "At the same time as the endometrium is generated, a self-sufficient intramural circulation network has been automatically formed, and it only needs to be connected to a dialysis machine to inject fresh blood, precipitate out waste blood, and then inject enough nutrients into the blood to make it 'live'." ”

Chen Chen nodded, those two pipes simulated the function of arteries and veins.

As for the blood inside, it is not ordinary human blood, but an emulsion (PFC) of perfluorotributylamine with oxygen-carrying capacity.

This substance is synthesized artificially and has a good oxygen-carrying capacity, the solubility of oxygen is twice as high as that of ordinary blood, and it can be biodegraded, so it is often used as a blood substitute in medicine.

"Good."

Chen Chen showed a satisfied look, patted the young man's shoulder and said, "Hannibal, are you interested in joining my next project team?" ”

"Is it the next step in the artificial endometrium?"

The young man known as Hannibal was in the eye, and as a professional biological talent, he could not fail to understand what this technology meant.

"Yes."

"I would love it, Boss!"

The blonde youth nodded emphatically, a young man who was extremely fanatical about biological science.

The blonde youth, formerly known as Hannibal Caesar, was a sophomore at MIT who won the Lemelson-MIT Prize last year for a very important paper in the field of synthetic biology in Science.

Because there was nothing to teach in the school, before he graduated, he was attracted by Chen Chen's invitation and became an employee of Blacklight Biotechnology.

In this young man, Chen Chen saw a terrifying potential.

If there are no variables, there is a chance that this young man will become a new discipline of biology decades later, alongside the likes of Darwin, Mendel, and Schwann......
