Crazy Human Grade Techniques

Looking at the various cultivation manuals in hand, Di Tou couldn't find any Earth Grade manuals that suited him. Further, he didn't know how cultivations worked in conjunction with one another. 

Was scattering one's cultivation and re-cultivating a thing that existed in this world?

Or were the effects of starting a cultivation manual permanent?

Thinking back to the way Fu Hao Xin was speaking, it seemed that there should be a way to start a new manual even if one had already started cultivating, simply picking up where you last lest off, but Di Tou had a feeling that it wasn't so seamless as simply choosing to swap.

It was likely there were resources and difficulties involved with swapping cultivation methods.

If that was the case, it seemed like it was perhaps a bad idea to mess around with these manuals, especially considering that none of them even seemed that good.
