After transmigrating to another world, Ye Hexiu watched the woman he loved become a pawn in a political marriage between powerful clans, while he himself was trapped in the struggle among those clans. He witnessed the desperate plight of ordinary people under their rule and experienced firsthand the cold-blooded cruelty of their power struggles. He decided he could no longer be weak and give in. He would do something to break through the shackles of this world and shatter the clans' chains, transforming it into the ideal world he envisioned.
To be honest, it's a bit of a reversal. The heroine suddenly changed. It's you.
