Sign-In as the Great Evil Dragon

He casually tapped a sign-in button on his phone and transmigrated straight into a chaotic world of gods. He became an innately evil little black dragon, complete with an Evil Dragon System that made him stronger whenever he did bad deeds! From then on, he was forced to go out and work every day, committing misdeeds wherever he went to complete sign-in tasks. One: Claim a mountain and rule as its king. Two: Spread a fearsome reputation. Three: Plunder wealth and build a dragon's hoard. Four: Imprison a princess! After nearly being beaten to death, dismembered, and skewered like a kebab by a bunch of terrifying upright apes, Otto felt the deep malice of the world. He decided to mend his ways and turn from evil to good... First, he'd lie low in some remote corner and build up his strength, then emerge once he was invincible! But time waits for no one. In the end, he still took the path of no return into evil, recklessly testing how far he could go before getting himself killed! Here's the question! How can you do bad things without getting beaten to death on the spot? Otto soon found the answer: he made a contract with a female knight who would take the blame for him, and completely let himself go. However, because of a loophole in the world, countless greedy and terrifying eyes fixed upon it. Throughout the Myriad Worlds, their fearsome legends are known to all. Wherever the interstellar insect swarm goes, not a blade of grass remains! Rampaging machines reap everything in their path, spreading poison throughout the great realms! The undead's horns sound the death knell for all life. The dimensional demons, whose ultimate purpose is to destroy every living thing... don't even spare the undead or machines. Players under the command of the "Main God" rampage through the Myriad Worlds! The War of the Gods brings the destruction and creation of worlds! And He is feared by every force of order and chaos, the end of all things! When black wings of death sweep across the sky, the world will face its final day.
