The necromancer of the Pokémon world

In a world where Pokémon and magic coexist, Lin Ye, a powerful necromancer, has emerged as a dominant force. As the strongest Ghost-type Gym Leader, he possesses the extraordinary ability to conjure Shadow Balls with his bare hands and command the loyalty of the undead. His journey began when he transmigrated to the Pokémon world, discovering that his mastery of necromancy granted him a unique advantage in raising Ghost-type Pokémon. He can form undead contracts with these Pokémon, allowing him to harness their power and rise to become a formidable Ghost-type Pokémon Master. As Lin Ye thrived in this new world, he stumbled upon a spatial passage connecting the Pokémon world to the magical world, paving the way for a calamitous presence that would travel between the two realms, forging contracts with numerous intelligent undead creatures. Years later, Lin Ye's remarkable prowess would be questioned by a lich's underling, who sought to understand the secrets behind his exceptionally powerful and unique Giratina, prompting Lin Ye to reveal the mysteries of his craft.
