Mad Viscount's words made the Emperor's brow furrow continuously, even though he knew the Mad Viscount's plan was very necessary. After all, if what he said was true, the entire world would gradually wither due to the lack of newborns.

If the genes of the Demon Race differ from humans, at least it proves there is still a turning point. But if the hosts of the Demon Race actually have genes identical to humans...

The Emperor could not imagine such a future. He felt that, if true, the whole world would be finished, and within fifty years, there would only be elders and no newborns.

The Empire would face extinction, and civilization would be completely wiped out.

This was a future he absolutely did not want to see.

Soon, they surged onto the Demon Race's initial island, but despite searching, they did not find any enemies.

It was nearly dawn before they finally found the enemy. 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

It was a combination of a young boy and a barbarian, with the barbarian leading a giant deer over ten meters tall, as if it were his mount.

"Follow the plan," the Mad Viscount immediately said.

"Alright!" The Emperor adhered to the arrangement made by his junior. In the next moment, thick golden armor appeared all over his body, and in his hand, he held up a golden greatsword over two meters high, looking just like a golden giant.

The enemy obviously also noticed the two men here. Quickly, based on experience, they judged that the Mad Viscount seemed to be the host, while the golden giant was the Heroic Spirit.

Thus, they were also prepared. The barbarian slapped the ground in an instant, and next moment, a small goblin-like monster appeared in front of the boy as a guard, and he and the giant deer charged towards the Golden Emperor.

...

"Fifth team!" Xue Dili finally found a Demon girl.

Her appearance was so thin, like a skeleton, that if the Cursed Blood hadn't sent back information, Xue Dili really couldn't have imagined this was a girl.

He fixed these people on a cross and knocked them unconscious, starting his research.

However, just like others, this girl's genes were also highly similar to the Ninth Apostle, and such similarity had even begun to distort their essence.

Xue Dili even felt that with everyone in a state of high gene similarity, did sexual reproduction still have a necessity?

The essence of sexual reproduction is for genetic diversity, for species evolution, and to better adapt to the environment.

The more primitive the life form, the more it relies solely on division or simple breeding, while the more complex and advanced species acquire genes from the outside to fill their gene pool.

This is the nature of the Cosmos.

But in this world, everyone's genes are highly similar to the Ninth Apostle.

Xue Dili even suspected that human reproduction in this world is not through sexual reproduction but mere cloning replication.

The gene of the Ninth Apostle has polluted the entire world, making all species evolve in the direction of the Ninth Apostle, just like how the appearance of all intelligent life in the universe evolves towards the Venerable King.

Over countless years, did this world emerge like this?

Xue Dili thought about it, or maybe only the participants of the Holy Grail War are like this?

All participants of the Holy Grail War are controlled by that unknown shadow, and after controlling the host, the shadow changes genes, and through copulation, purifies and expels all other genes in the entire world, creating a population completely twisted by the Ninth Apostle's genes.

Why would they do this? Or rather, why would this situation arise?

Xue Dili thought of a virus on Earth called Wolbachia, which is the most extreme virus, existing in more than 99% of the world's insect bodies.

The function of this virus is to enhance the insect host while, like a Demon's contract, severely restricting the insect's reproduction.

That is, mosquitoes infected with Wolbachia can only breed with mosquitoes infected with the same virus. If they mate with uninfected mosquitoes or mosquitoes with other viruses, Wolbachia will instantly destroy the other's reproductive ability, ensuring only Wolbachia-infected mosquitoes can successfully breed.

Xue Dili knows that in his country, the biological method to control mosquitoes is to release different exotic Wolbachia mosquitoes into the local environment. These exotic mosquitoes instantly destroy the reproduction ability of local mosquitoes.

Wolbachia is like a Demon contract, giving the infected individuals stronger physical fitness, better combat capability, and longer lifespan, but the price is the complete control of the host's reproductive rights.

This virus was once used as a research material in his Parallel World self's hands, but in the end, he chose bacteriophages as the vehicle against the Divine Tree.

And now this world is very much like a place ravaged by this virus, but on Earth, Wolbachia is only spread among insects, and so far, there is no case of human infection.

But this world is different. The entire world seems to have been completely polluted by the Ninth Apostle's genes, at least in the samples found by his Cursed Blood, the whole world appears to be entirely hijacked by the Ninth Apostle's genes.

Xue Dili thought, if luck is good enough to successfully save this world, he must go for further education in biology.

Or perhaps let his Parallel World self tutor him; the current situation is no longer something he can solve by mere speculation.
