The ancient primordial world was indeed too crude. Xu Zhi did not quite agree with the reincarnation system of the ancient primordial world.
There was an underworld in the Sorcerer world.
It could be considered as reincarnation. It would absorb the souls of a world into it, and the souls would live a Second Life inside. They could also cultivate and use these souls to nourish the netherworld, constantly growing into a high-energy world.
There was a creation wood in the primordial world.
However, it was not reincarnation. Its soul energy did not improve the world. Instead, it was condensed into a fruit that was only provided to one person to improve their realm.
They were originally a cultivation system that 'absorbed the aura of the living beings of the world'. Their souls were like a stick of incense, constantly emitting Joss flames ... And killing for an incense's time was simply too absurd.
