Beyond the Realm of Ninjago

One day in 2024, some clueless middle schooler suddenly remembered a cartoon he watched when he was three and decided to watch it again. Then his roommate's kettle suddenly fell onto the protagonist's phone while he happened to be holding it and charging it, electrocuting him to death and making him transmigrate. He was then transported to a cloud with buildings on it, where someone appeared and told him they needed to find an extremely lazy person to be the master of this place, because the previous one worked so hard that he wore them all out. Then he saw Master Wu and the others, and began a story spanning all of Ninjago, from Season 1 onward. A semi-invincible story.
