How can the system know if a person reincarnated, but can't see when a soul possesses another body? The story is definitely full of holes like @Grasshopper said.
Extremely slow for a system novel. How the f**k are his disciples surpassing the MC by so much when he has a system? One can argue reincarnation, but what is reincarnation in the face of a walking cheat?
The power scale of this novel is weird. The MC controls Ten Thousand Daos, but having hard time killing someone with one Dao. Also, that Human Dao Skynet record is annoying because it's takes at least 1/3 of the chapter.
