It was the best cheat in the vast and ancient world!
Its origin could be traced back to Trailokya and it was the highest law!

Three years ago, three living creatures fell from the sky. King Monroe of West Ridge got one of them and he conquered six countries to unite West Ridge.
Wu Zhao of the Big Zhou Dynasty in the Southern Wasteland got another one of the living creatures. She dominated all 19 clans there and became the top figure in that region.
Owen Bertram also got one of the living creatures. Yet three years had passed and he was still a nobody. Nothing had changed for him.
However, he soon realized that the tiny loach that he got three years ago was actually the biggest cheat in the world.
Moreover, it led him on a non-stop journey of becoming the biggest winner in life!
