The Forgotten Hero Decides to Become a Profiteer

Chu Chen was bound to the "Ninth Demon Lord" system and was told that he would be forgotten by everyone after saving the world. He reported the system backhand: "The Overlord Clause must be modified!" From then on, this supposedly tragic hero took up his abacus and opened a magic energy recovery company. "Demon energy? That's my raw material." "Hero? That's the spokesperson of my company." "Forgotten? When I let the whole world use my products, spend my money, and be unable to do without my services——" "Look at this world, how dare you forget me!"
