From the Start, I Slayed the Cockroach Heavenly Emperor, Becoming the Only God of Slaughter in the World

In an era of high martial arts, exotic beasts run rampant. The winds of martial arts universities never reach the homes of ordinary people. With his father paralyzed and his mother ill, Su Chen has no choice but to drop out. Then... he gains the ability to grow stronger by killing enemies, becoming an overpowered demon king who slaughters countless Cockroach Heavenly Emperors from the start. “Ding! You killed a cockroach. You’ve grown stronger.” “Ding! You crushed an ant. You’ve grown stronger.” “Ding! You poisoned a rat. You’ve grown stronger.” He starts by killing a cockroach, then goes on to slaughter mythical dragons that cross the void. Kill monsters to grow stronger, until no one in the world dares call themselves supreme! I’m not very good at writing blurbs, so just read the story.
