Pollute First

This was Oedmeir's research result: inoculation theory.

The Emperor had created the Primarchs' bodies from his own genes, granting them biological life, then filled their souls with indescribable substances from the Warp.

"Mm-hmm! Do you remember the Old Tang in Lin Fan's stomach? He told me about his experiences aboard the Golden Ark. Once Old Tang accumulated to a certain amount, it could create plants with the essence of life. Behold another result
