Crossover anime/manga, immediately transmigrated after death

In a bizarre twist of fate, Zhang Yang finds himself transmigrated into a world that brings together a diverse array of anime and manga series, specifically enrolling at the prestigious Shuchiin Academy in Tokyo. As an orphan blessed with immense wealth, he initially sets his sights on a humble goal: building a harem. However, his entrepreneurial ventures take an unexpected turn, and he stumbles upon a remarkable stroke of good fortune. Following his death, Zhang Yang discovers he possesses a unique cheat ability that allows him to traverse into new worlds, with the caveat of a seven-day cooldown period and the ability to return to the moment before his inter-world travels. As he navigates this uncharted territory, he begins to wonder if he will indeed strike gold. Zhang Yang's journey takes him to the Ming Empire, a realm that appears to be deeply rooted in martial arts, where he encounters a cast of intriguing characters, including a naive young warrior, a compassionate yet stoic master, and a saintess resurrected from the dead. The legend of the revered martial arts master, Chi Yuan Zhenren, also begins to unfold, leaving Zhang Yang to ponder the extent of his newfound reality and the possibilities that lie ahead in this ever-expanding anime and manga landscape.
