Deriving the Formula

"The Spirit Swallowing Gu seems pretty good, and the Mind Control Gu also seems decent."

Zhou Feng had given some thought to how to create the Heavenly Heart Gu before.

He would choose a Gu insect as a foundation, then forcibly contaminate it with the Sky Swallowing Gu to create an inferior version of the Sky Swallowing Gu.

Such a simple and brutal method would naturally bring many hidden dangers, but it was enough.

He had no intention of reaching perfection in one step and directly deriving the Heavenly Heart Gu into a flawless form.

As long as he could prove that the Heavenly Heart Gu could suppress other Gu insects, countless Gu cultivators would join in researching it.

"As long as I spread the Heavenly Heart Gu, I only need to monopolize the core material needed to refine it. Then I'll make a fortune."

The first thing Zhou Feng thought of was blood essence purified by the Sky Swallowing Gu.

It seemed that blood essence purified by the Sky Swallowing Gu naturally carried the Sky Swallowing Gu's aura.

And the Sky Swallowing Gu was unique to him. Wasn't that the perfect material to monopolize?

The Heavenly Heart Gu could be refined from all kinds of Gu insects, and he could generously release the formulas for refining those Gu insects.

However, the formula had to include blood essence purified by the Sky Swallowing Gu.

He would call it Heavenly Heart Blood.

Besides that, he also needed to create a substitute version of Heavenly Heart Blood.

The reason was simple. If he were the only person in the world selling Heavenly Heart Blood, even a fool would know something was wrong.

Therefore, Zhou Feng had to create a substitute for Heavenly Heart Blood.

That way, he could blend in among them
