After learning that the key to the realm of the badger was to integrate the genes of other species, things became simpler.

Although the generals of the Eastern Continent did not know how to extract the "blood soul essence", it did not prevent Bai Yuqi from deducing the principle through brain supplementation.

According to the descriptions of the generals of the Eastern Continent, the sect to which they belonged used a hollow silver needle to divide the "blood soul spirit" into seven seven hundred and forty-nine times, and pierced them into their bloodlines, each time injecting more than one time, until they awakened the blood soul.

In this process, they will have fever, high fever, swinging and other adverse reactions, and they may also die violently because they are not suitable for the injection of blood soul essence.

Each person has different types of Blood Soul Essence that are suitable for them, and the concentration of Blood Soul Essence that they can withstand is also different.

In general, the stronger the body and the more stable the gene structure, the stronger and higher the concentration of alien animal genes that can be withstanded.

And the person who invented this method at the beginning was really good at it, and after he succeeded by luck, he spread the method, and then pit countless people in future generations!

Bai Yuqi was very suspicious that the first person to eat the crab was purely injured in the battle with the alien beast, and as a result, after the blood of the alien beast was mixed in the wound, he didn't die, thinking that he could become stronger in this way, but in fact the probability of success was low.

Later people couldn't resist the temptation to become stronger, but under this method of colonizing the blood of alien beasts, they suffered heavy casualties, so they slowly developed the method of colonizing in small quantities...... Isn't injecting the blood soul essence with a silver needle forty-nine times just a process of skin testing and adaptation?

The reason why the spirit of these four beasts of fierce beasts was chosen was purely because it was found in countless experiments of death that the spirit of these four beasts had the highest success rate.

And in genetics, Bai Yuqi and they are much higher than the Great Wilderness Monks.

Even in terms of controlling souls, Bai Yuqi, a spellcaster, is definitely an expert.

Therefore, they only need to conduct a series of genetic tests, and they can even extract absolutely safe, non-rejection blood soul spirits and breed them into the soldiers under their command in batches.

It's just that whether to breed xenogenes into the soldiers under his command still makes Bai Yuqi hesitate.

After all, biological experiments are often accompanied by the risk of physiological mutation, which is known by those aliens and humanoids among the natives of the Great Wilderness.

Even if the integration of xenogenetics is successful, there will still be hidden dangers of physiological variation and gene mutations, and even this xenogeneous gene will be passed on to offspring through reproduction.

If you are not careful, it is very likely that the entire race will be contaminated by this gene through marriage, and it is not impossible for the entire race to perish once a malignant genetic disease appears.

After thinking about it again, Bai Yuqi still decided to study the safe "Blood Soul Vaccine" first, and as for whether to vaccinate with xenogeneous genes, it was left to the fighters to choose.

However, in order to prevent genetic contamination of the population, strict restrictions must be put in place.

For example, only soldiers who have already married and have offspring are allowed to be vaccinated, and their reproductive ability is castrated after vaccination.

Although it is a bit cruel, it is a necessary means to prevent genetic contamination from harming the entire ethnic group...... However, it seems a bit inhumane to be castrated directly, so it is better to change it to racial reproductive segregation, after all, the warriors who have been inoculated with xenogeneous genes are no longer strictly speaking pure-blooded human races.

The racial and reproductive segregation measures are limited to the races of the cross-border Tang Army and the Ertesian world, but they are not limited to the indigenous races of the Great Wilderness, after all, they themselves have already messed up their own bloodlines.

Strictly speaking, the entire ethnic group in the Great Wilderness Realm has long been genetically contaminated.

The reason why there is no outbreak of malignant genetic diseases that endanger the ethnic group is not known is because their constitution and genes are special enough and compatible enough, or whether it is just pure luck enough, or this kind of heterogeneous genetic mixing does not affect the bloodline of the ethnic group?

Either way, Bai Yuqi would not risk a population crisis to try it until he thoroughly studied it.

And even if he is sure that there will be no danger of genetic contamination, he will not completely relax the restriction on the inoculation of blood soul spirits, and at least he will retain a certain group of natural people as pure "gene seeds" to prevent accidents.

The development of the "Blood Soul Vaccine" is going well, after all, the Western Cloud Empire has a huge gene pool of alien beasts in its hands.

Almost any creature that appears in the land of Xiyun has been collected and stored in the species' gene bank as a reserve.

With the "Sky Eye System", it is still very easy to do this, and there is no need to worry about the test subjects used for human experiments.

The biochemical spore body cultivated by the biochemical spore factory under the command of Tai Sui Vortex, in addition to having no soul and self-awareness, can be adjusted and cultivated into samples required for human experiments according to needs, and there is no problem in slicing as much as you want.

Under such conditions, it is enough to support large-scale human experiments, to provide more detailed experimental data, and to recycle when it is used up, without wasting at all.

It is simple to extract the genes of alien beasts, remove cellular memories, remove genetic information, fuse human genes, and cultivate a safe blood soul vaccine with no rejection reaction.

But the reason why the blood soul spirit can allow humans to inherit the ability of the alien beast to involve the power of the law is mainly because of the trace of soul power contained in the alien beast gene, so it can still form the so-called "beast soul totem" after entering the human body.

Simply inoculating the genes of the alien beast can only allow human warriors to inherit the physical strength of the alien beast and the physical ability derived from the bloodline, but they cannot inherit the power of the law of the alien beast.

For example, the leopard among the generals actually inherited the "speed" talent of a feline beast called "Swift Leopard", allowing them to burst out with amazing speed in a short period of time.

This innate ability, which involves the power of the law, can no longer be explained by the laws of physics.

Instead, it has entered the metaphysical concept on the mysterious side, and it is not easy for anyone to lift the coffin board, but it is completely unreasonable and will be over.

Without this trace of soul power, even if it is inoculated with the alien beast gene, it will not be able to awaken the "blood soul", let alone activate the "beast soul totem" to exert the ability of the law.

The generals are usually captured by the foreign beasts, and only after the sect overhaul can extract their bloodlines, plunder their souls, and refine them into "blood soul spirits" to inject them, which is equivalent to a person awakening the blood soul and killing a foreign beast.

This is the same as hunting musk deer for incense, catching bears for bile, and killing chickens for eggs.

It's okay to have a small batch, like Bai Yuqi who plans to improve the overall combat power of the Western Cloud Empire, where to go and find so many foreign beasts to take blood and take souls? Even if it is artificially cultivated, it is not cost-effective.
