Jiang Hai also didn't continue asking, instead he started reading a book.
It looks like he took in Gu Shanhai's idea.
As for what cultivation technique to give Jiang Hai, Gu Shanhai had already prepared it.
It's best to use the "Yin Yang Formless Divine Skill".
No need to worry about being tricked like Green Sorrow and Lan Meng, because theoretically, Jiang Hai is the formless form of yin-yang fusion.
Originally Ji Shan was, but later due to the Ji Family bloodline and the formation of great karmic effect, the formless was forcibly squeezed out, making everything convenient for Jiang Hai.
In other words, the other party looked down on this enhancement, they had better options, so the karma took effect.
It's equivalent to borrowing the body to remodel but not really seizing the nest.
The "Yin Yang Formless Divine Skill" requires either integrating yin-yang or being the formless born out of yin-yang.
