The Green Silk Worm, Demon Ant, and War Bee were all candidates for devouring those few Gu.
As he waited, he took out the manual of the Puppet Gu Secret Technique and studied it carefully. It could be seen as a last-minute attempt to learn some knowledge about controlling, nurturing, and fusing Gu.
It really was like sharpening your axe just before going into battle, a dull axe could still shine with some effort.
Through studying, he gained some new insights into controlling and nurturing Gu.
The Puppet Gu Secret Technique mentioned the art of fusing Gu.
That involved fusing two Gu, either similar or different, into one. The purpose was to elevate their ranks and give them greater power.
There was even a tiny chance of witnessing a completely new transformation.
The manual mentioned that fusing a Water Gu with a Grass Gu could potentially create an Ironskin Gu with extremely powerful defensive capabilities.
This method of fusion also existed in insect cultivation.
