Pure Humans

Guilliman intends to send these newborns to all the immigrant worlds of Ultramar.

They will grow into adulthood quickly in the biological culture chamber and receive basic education.

Then they marry and have children on various planets, gradually improving the human genes on those planets.

This only used a tiny fraction of the 100,000 tons of Gene-seed, because Guilliman wanted to ensure that there would be at least a portion of truly pure-blooded humans on every planet.

The remaining Gene-seed were all used by him for the genetic modification program of the Imperium citizens' descendants!

It means if you want.

You and your partner can come and collect a pre-synthesized Gene-seed to have a child who is completely unrelated to you by blood.

When he announced the introduction of the "Pure Old Terra Gene Template" to optimize the population, it did not trigger cheers, but rather an ethical storm that swept across Five Hundred Worlds.

This is also a downside of communication being too fast; people are often too quick to take things out of context.

When faced with a situation, most people prioritize their own interests and act according to their own ideas.

Instead of understanding the whole picture, its significance, and its impact on the future.

The opposition first came from the Ecclesiarchy.

A fanatical cardinal roared during his missionary work:

"This is blasphemy against the Emperor's human form! Every person created by the Emperor is sacred; to alter genes is to deny His will!"

His speeches drew millions of followers until the Chief of the Calgar Chapter Master personally led a squad of Ultramarines to the foot of the pulpit.

Calgar didn't draw his sword; he simply opened the Dataslate and projected a series of shocking images:

The twisted limbs of the lowest-level inhabitants of the Hive City due to millennia of accumulated radiation; the family lineages of the Agri World paralyzed for generations due to genetic defects; and the entire settlement on the border planet that went mad during adolescence due to latent mutations.

"Tell me, Your Grace," Calgar's voice was as calm as the deep sea, "Are these pains, these curses we are born with, the manifestation of the Emperor's will?"

"Or is it that we finally have the ability to alleviate the suffering of our compatriots, but we must stand idly by because of a rigid understanding of 'pure'?"

The bishop opened his mouth, but ultimately could not answer.

The crowd fell silent.

Greater resistance comes from within.

At a Ultramarines think tank meeting, Chief Think Tank Tiglius bluntly stated, "Father, this is dangerous. By what right do we define 'superior' genes?"

"Today we say certain traits are more ideal, tomorrow we might say that people with low Psionic Energy are 'not good enough.' This is a slippery slope toward the tyranny of eugenics."

This was certainly not his opinion; the Ultramarines were forever loyal to Guilliman. The Chief Librarian had simply summarized what he had collected about the thoughts of people from various planets.

Guilliman listened patiently to all the objections. Then he did three things.

First, he made all the data public.

Through the holographic network, every citizen of Ultramar can see statistics on the association between genetic mutations and diseases.

Seeing the trend of human gene pool degradation over the past 20,000 years, and the potential health disasters that the next five generations may face if left unchecked.

Second, he established the strictest ethical framework. The "Life Cradle" program is entirely voluntary and only provides "optimization" rather than "design".

Many couples can also choose to use genetic template materials that have been safely processed.

This significantly reduces the risk of offspring inheriting 1,278 known serious genetic diseases and improves their basic health.

There is no customization based on appearance, no selection based on talent, and no so-called "upgrade package".

Each fetus participating in the program undergoes dual review by an ethics committee and randomly selected civilian representatives.

Third, and most importantly, Guilliman personally went to the communities most affected.

In the Industrial World of "Slag City," he met a group of parents whose children all had a genetic defect unique to the area that prevented them from living past ten years old.

They were terrified that their children would be replaced by new children, and that their bloodline would disappear from the world forever.

It wasn't a grand reception, but rather, in a shabby community center, the Primarch sat in a plastic chair, listening to a mother recount her experience of burying her three children.

"I could still cry when my first child passed away."

The woman named Leah said her eyes were as dry as a desert, "By the time my third child passed away, I had forgotten what tears were."

"We tried praying, we tried donating, we tried everything."

If... if there truly were a way for my next child to have the chance to live to see the sky no longer gray, why would I refuse?

Because some important figures on other planets find this 'unnatural'?

She looked directly into Guilliman's eyes. "Sir, tell me, which part is more 'natural' to watch your child slowly die?"

Guilliman remained silent for a long time.

When he finally spoke, his voice was very soft, but everyone present could hear him clearly:

Nothing is more natural than a parent's desire for their child to grow up healthy.

This plan is not about creating Superman, but about restoring the most basic right to survival that has been taken away by chaos and suffering.

The footage of that moment was disseminated, changing the views of countless people.

The actual operation was a massive and precise project. The ten tons of genetic material from the "Invincible" universe, which had undergone extreme screening by the system, were distributed into five hundred highly secure biological gene banks.

Each "Life Cradle" center is like a small chapel.

Instead of a cold, mechanical feel, there is warm lighting and soothing music (some worlds even use classical music from Old Terra).

And highly trained consultants, many of whom are themselves parents of children with genetic diseases.

The process is rigorous and transparent: genetic screening, consultation, informed consent, and multiple confirmations are required before proceeding to the very early intervention stage.

The effects are gradual.

When the first batch of "Children of the New Era" were born, the attending physicians noticed some subtle but significant differences:

These babies had clearer cries, generally higher Apgar scores, and 86% fewer items were marked as "needs observation" during newborn screening.

More subtly, as these children grew up, teachers' reports began to flood the data center.

They learn faster, concentrate better, and have a significantly lower incidence of infectious diseases.

These pure-blooded humans were indeed favored by the God-Emperor.

They can essentially be considered pioneers of humanity.

At the military assessment level, the data is even more astonishing.

In routine conscription tests, recruits from participating families showed an average improvement of 18-23% in physical fitness and neurological reaction speed compared to the control group.

Even more shocking is the Psionic Energy talent screening:

Although the overall proportion of Psyker did not surge, the number of recruits whose Psionic Energy met the initial selection criteria for Grey Knights increased by 400%.

The number of people has increased from one per 10 billion to one per 2.5 billion.

This directly means that in the future, Ultramar will not only be able to build a more powerful conventional army, but may also have its own homegrown Psionic Energy special forces.

Guilliman was entirely in the right to suspect that the Emperor had been closely monitoring the entire affair ever since he learned that pure human genes had appeared in his possession.
