As the era developed, some people gradually realized that regardless of whether it was the primordial world or the world of potions, there was an invincible great emperor in every era. He was far stronger than the other genius great emperors of the same era. He ruled over an entire world and was invincible.
Other than physical cultivators breaking the Dao through force, the primordial world spoke of the heart, and The Fiend herb world spoke of truth. They were all related to the state of mind.
Geniuses of the same generation would always have to fight each other in the same realm. Even if they had the same talent, the gap would gradually open up because of the victory and defeat.
The winner would gain confidence and advance courageously by defeating their old enemy, while the loser would have a shadow in their heart, and the gap would grow bigger and bigger.
