Pokémon: I, Ash, Purify Dark Arceus

After reaching the Alola Championship and returning to Zhenxin Town, Xiaozhi was awakened by a nightmare that lasted for twenty-five years - in the dream, Dark Arceus tore the world apart, and Pikachu protected him from a fatal blow. The moment he woke up from the dream, the real timeline had been forcibly tampered with by a mysterious force, and even Arceus couldn't deduce the future direction. He immediately decided to set off: to pick up the Bidiao who insisted on guarding the Joban Forest, to retrieve the fiery monkey in special training, to visit Lapras who returned to the team, to retrieve the sticky dragon in the wetland reserve, and even the Koga Ninja Frog was on the list. The existence of darkness that has been sealed in the Flame Mountains for five thousand years is about to break out. The real light bringer must awaken before the age of eighteen - the number one candidate targeted by Arceus is Xiaozhi. The Dark Remnant brought the Dark Stone to lock onto his aura first. When Pikachu alertly raised its tail, Ash unknowingly climbed onto Kentero and ran towards Viridian Forest - behind him, the three forces of Team Rocket, the Security Team, and the Sasaki Group were rapidly approaching his coordinates. Only when all the old friends return to the team can he face this fate that spans five thousand years. This novel and its characters are purely fictitious.
