When the last prodigy level esper on Earth disappeared, Earth was in deep trouble of becoming another species’ colony. The ordinary Han, with his intelligence and hardworking character, was able to make a fortune after “accidentally” stepping into the world of dark net, later purchasing an esper power crystal that brought him the ultimate power that changed the fate of the universe.
