Yang Tianyao looked at the ten bottles of milky-white [Energy Serum] inside the metal case, a fervent gleam in his eyes.
"I have a feeling we can find the answer to Ye Fan's advancement in here!"
The laboratory's deputy directors and research team leaders all gathered around.
They had developed the "Special Ability Amplification Serum" together. If they could have overcome its side effects, they would have done so long ago.
It was precisely because they could not currently overcome those side effects that the final product had turned out this way.
Ordinary soldiers could become Tier 1 peak Superhumans after taking their "Gene Serum" and "Special Ability Amplification Serum" in succession.
Mass-producing powerful soldiers!
During their research, they had left themselves a fallback: problems they could not solve now would inevitably become solvable as energy research deepened and humanity's understanding of energy crystal core energy reached a new stage. Then they could eliminate the earlier potions' side effects and resolve this predicament.
It had been a last resort.
The zombies' time lock would not wait for humanity to slowly develop powerful energy potions. Geneticists had predicted it back then-in fact, they could say with certainty that all ordinary evolved zombies would become Tier 1 evolved zombies after six months.
