Humans are the spirit of all things; Gu are the essence of heaven and earth.
I was an entomologist, but my soul crossed into the body of a young insect cultivator in a world of immortals.
I inherited the Growth Gu, which its original owner considered trash, and gained the ability to see how much anything could grow.
I firmly believe that no Gu are useless, only Hosts are. It all depends on how strong the Host's imagination is.
I discovered that incomplete recipes also had growth potential, and even a Gu recipe missing all but one ingredient counted as incomplete. That made things simple.
All I had to do was write down a random ingredient and guess the rest. If the growth potential disappeared, I knew I'd guessed wrong. If it went up, I'd guessed right, and I could keep guessing.
Once I reached one hundred percent, it meant I had successfully guessed my way to a Gu recipe.
The same method worked for cultivation techniques, pill formulas, artifact blueprints, formation diagrams, wine recipes, poison recipes... I could guess them all.
From the Nine Deaths Divine Art to the Purgatory True Demon Art. From True Soul Transformation to the Heavenly Demon Disintegration Divine Art.
While others cultivate the Way of Slaughter, I cultivate a Great Way of my own making.
When I looked back, I had already become invincible in the mortal world...
