My name is Chen Jinxun. On the day I turned 30, I was supposed to have a bright future. I actually died and became an NPC in the opponent's game. I am an NPC but I have the heart of the protagonist. Since the protagonist cannot defeat the demon king, let me do it!
Alas, but why is the Demon King so weak...
Cowardly Demon King × Progressive NPC
Intention: Be strong, climb to the top, overcome adversity
