Game of Chaos

Nicholas Dendi was a middle-class dimensional explorer who died due to a dimensional rift opened by a god who broke the laws of the universe. He was resurrected to a world that was preparing to start a war with the gods. With a system implanted in his soul, Dendi awakens his immense power and makes the gods threaten his existence. Dendi had to participate in the devastating war because he had a contract binding his soul and also so that he could return to his world.
