Demon King and Hero

The protagonist is ruthless, utterly rational, conquers another world through force, leads his home plane, devours other worlds, and becomes the strongest.

It was an ordinary day, just like any other. Long Bugujue had finally had enough of being betrayed by his family and friends, and decided to end his life. This means he gets the chance to become a hero, but he has no talent at all and is scorned by the other heroes, including the goddess. In the end, the goddess throws him straight into the hardest world: one conquered by the Demon King. It is nothing less than a death sentence. At last, he stands up.

I cast aside the light and join the darkness. I will become the strongest.
