The world was born for him and fell for him.
He is not a demon or god with an extremely long lifespan, because both demons and gods are limited by the world and will perish with the world. As for Ye Qi, he does not know how long he has existed. Because the world is destroyed, he will fall into a deep sleep, waiting for the birth of a new world to wake up again, but he is the only one who will always be stronger than himself, because he is his own guardian. He wakes up, he wakes up, he sleeps, he stays awake.
However, due to some reasons, the guardian erased Ye Qi's memory. With the erasure of memory, Ye Qi has completely become a human being, with no magic power, no memory, and even... No intention. The guardian induced him to come to a parallel time and space, and... He had to find the guardian to unlock the seal.
