The Demon Lord of Ten Thousand Demon Cave Who Is Forced to Do Good

The Demon Lord, the most ferocious destroyer in the universe, has personally ended countless civilizations. In order to become stronger, he personally activated the strengthening system left by his ancestors, but unexpectedly activated the good system. Want to destroy a civilization? Save another civilization first. Want to kill someone? Save a hundred people first. The Demon Lord began his career of being forced to do good, helping impoverished planets and defeating villains. In three thousand years, he saved hundreds of millions of lives. He rescued a hunted interstellar fugitive and later became the largest arms dealer in the galaxy. He rescued a dying Zerg queen and later unified the Zerg tribe and became his most effective subordinate. He rescued a prince who was hunted by a giant civilization and later became the emperor of a star region. He rescued a little girl who was exterminated. He later became the best swordsman in the universe. He rescued a robot who wanted to commit suicide. He later controlled the omnic network of half of the galaxy. The demon lord cursed and became the most recognized good person in the universe. The inner OS of the Demon Lord: "When I accumulate enough merit points, I will be the first to destroy you." However, before he had enough merit points, the sword of the universe's greatest swordsman pointed at the little girl he had saved, "Without you, how could I have been left alone in pain?" Those who were rescued discovered a common truth: being rescued by the devil is the cruelest curse in the universe. Because the Demon Lord's rescue was never for them. They survived, but became zombies. Demon Lord: I have provoked you, who is the biggest BOSS in the universe? ! !
