Doing Good Brings Disaster to the World, Doing Evil Saves All Living Beings

【Unlimited energy + invincible from the start + anime worlds descend + behind the scenes + ensemble of secret identities + fictional world】 My name is Jiang Ming, and I'm a 996 programmer. While flying at an altitude of ten thousand meters, I was struck by a golden light and gained something called the "Ideal Engine." Unlimited energy, max level from the start. As long as I can work out a complete scientific principle in my head, I can turn any idea into reality. But this damn thing has a rule that could get me killed. If I use this power to do good, the world unleashes an equal amount of disaster. If I do evil, the world randomly drops supernatural artifacts and blessings on ordinary people. The whole world is asking: Why did the supernatural age suddenly arrive? Where did the monsters come from? Where did the Awakened come from? No one knows the answer. Because Jiang Ming, the culprit behind it all, is pretty troubled by the whole thing himself. Should he be the Demon King or the Savior? In the end, Jiang Ming chooses a third option: be the Demon King and the Savior at the same time, and enjoy the show as an amused bystander. "Can't be helped. I'm both the source of calamity and the supreme god of salvation. What, do you want to pick a fourth option?"
