When Hantian was two years old, Yi became a demon, because only demons can grow faster.
When Hantian was five years old, Yi broke the seal and left the solar system.
Because the seal that Yi broke, it also let the creatures in other places know that there are still creatures here, so Yi left a seal and a purple jade pendant.
Then, thirteen years after Yi left, alien creatures arrived.
Later, when Han Tian knew that all this was done by his half-brother, he began to look for his brother. He wanted to ask him, why did you do what you did? Are you doing it for the world or for yourself?
