Two invention-related, one combat-related, and two individual enhancement-related new technologies cost Li Lin a total of 10 skill points.

The basic prerequisite skills for the three different routes were upgraded from lv8 to lv12, which cost him a total of 12 skill points.

Currently, Li Lin has 24 skill points left, so there is no need to spend them on upgrading skills.

Almost instantly after adding the skill, a large amount of knowledge suddenly appeared in his mind.

Fortunately, he had previously drunk the "activity enhancer", which further improved all aspects of his physical condition, and he no longer experienced the same discomfort as before.

Afterwards, Li Lin quickly sorted out the newly acquired knowledge.

"Quantum theory" is purely theoretical knowledge that introduces the principles of quantum-related fields, but it is basically just "paper talk".

However, relying solely on this technology, Li Lin can greatly improve the computing power of computers and intelligent brains, and can also apply it to the communication level, thereby expanding the range and speed of communication.

As for issues of communication security and encryption, there is no need to consider them at this stage.

In addition to "quantum theory", what Li Lin is most concerned about is "genetic engineering" for individual enhancement.

He uploaded the technology of "zero-element synthetic materials" to the database of the intelligent brain and asked it to arrange the relevant production line issues.

With more advanced new materials, in order to fill the gap in the capital chain and avoid financial problems, Li Lin decided to start selling various types of compressed materials that he did not need.

The mechanical engineers, which have been stripped of many functions and can basically only be used as coolies, will also be listed under the name of the Gilaman family and sold on a pre-order production and delivery basis.

There is no need to worry about the workers' jobs, because the price of a low-end mechanical engineer is several times that of a low-end power armor.

Even if you add the cost of food, clothing, housing and wages for the workers, and equip each of them with a set of power armor, it is still not as much as the cost of replacing mechanical engineers.

It is precisely because of this that Li Lin adopts this method of pre-order production and sales.

Moreover, he actually did this on purpose.

Otherwise, the two cities, which have just stabilized, will once again face new social contradictions due to the unemployment rate problem, leading to a sudden drop in stability.

But even so, those big families who have seen the functions of the normal version of the mechanical engineer will still fight to buy the low-end version of the engineer.

According to Li Lin's prediction, those families might conduct research on mechanical engineers on the one hand, and let them serve as fearless guards on the other hand, even if they no longer have weapon systems.

As for those families who tried to crack and reverse-derive the mechanical engineering blueprints, he had no worries at all.

Not only do other families simply not have similar technology, even if they could really crack and study it, it would take at least decades.

In addition, in order to be on the safe side, Li Lin also set up a program for the mechanical engineers. When they are forcibly dismantled or destroyed by external forces, the mechanical engineers will activate the self-destruct program.

"Self-destruction" does not mean explosion, but burning all the key parts inside the mechanical engineer to prevent others from taking advantage of the opportunity.

After completing the corresponding arrangements, Li Lin went to the basement of Jiraman's mansion.

This was originally an explosion-proof room and training ground.

However, with his arrangement and Kalina's support, part of this place has been turned into a safe warehouse for storing star iron, and the other part has been transformed into a chemical and biological laboratory with a purely sterile environment, equipped with various high-tech equipment made by him.

Because there has not been much time to study various genetic technologies before, Li Lin plans to give Zach to himself first. Recently, he has cultivated a lot of cells for experiments.

Zack's birth, transformed from alchemical waste venom into a living being with human thinking, was an almost impossible accident.

Because his cells have been cut off from the mother body, they only possess a certain biological instinctive consciousness, and are very capable of division and regeneration. The production of the Glimmer Potion refers to the principles of this type of cells.

Using this special cell type is more effective than using mice for genetic research.

Of course, if we want to apply it to humans in the future, experimental testing on mice is still indispensable.

Li Lin transformed his clothes into a full set of protective clothing, and carefully controlled the robotic arm to cut a small piece of cells from the culture dish and placed it on the workbench.

In order to avoid trouble, this genetic experiment project needs to be analyzed and assisted by an intelligent brain, and the equipment used is professionally customized and specifically used for "genetic engineering" at the microscopic level.

Li Lin took a deep breath and immediately concentrated. He first took the sharp scalpel handed to him by the robotic arm, cut through the thick epidermis of Zach's cells, and then injected nanorobots into the experimental material.

This is the "protagonist" of genetic engineering at the microscopic level.

After nearly a day and night of sleepless research without eating or drinking, Li Lin practiced the applied techniques of the individual reinforcement route.

For example, "neural tissue engineering" studies cell regeneration and enhances the development of neurons, axons and synapses.

Through this micro-engineering, if the original regenerative capacity of Zach's cells was "1", then now its regenerative capacity has directly increased several times to the level of "5-8".

Not only that, Li Lin also conducted a "genetic test" on it, determined its extremely special gene sequence, and combined it with the relevant technology of "gene map recording", and then cut its regenerative ability through "gene cutting" and related tools, successfully separating this small piece of "flesh and blood" from the "regenerative ability" and making them "independent" existences.
