Kill Emperor Cockroach at the Beginning, the Only Killing God in My World

In the era of high martial arts, strange beasts cause disasters. After all, the wind of the martial arts university cannot blow into the homes of ordinary people. Faced with his father's paralysis and his mother's illness, Su Chen was forced to drop out of school. Then... He gained the ability to become stronger by killing enemies, and became a super devil who killed countless cockroach emperors at the beginning. "Ding, kill a cockroach, you become stronger" "Ding, step on an ant and you will become stronger." "Ding, poison a mouse and you will become stronger." Start by killing a cockroach and end up slaying a mythical dragon across the void. Kill monsters to become stronger, kill until no one in the world dares to respect you! I'm not very good at writing introductions, so you can read the text directly.
