Starting from Ainz Ooal Gown, simultaneously traveling through time

In a stroke of luck, Leylin finds himself transported to the world of the Undead King, but his arrival occurs over 200 years before the catastrophic events that would unfold. As fate would have it, he is deposited in the country of Inberia, where a formidable dragon known as the "Coffin Dragon King" threatens to destroy him. However, as a protagonist in a simultaneous transmigration story, Leylin possesses the unique ability to tap into the powers of his counterparts from other worlds, including Game of Thrones, Lord of the Rings, Dragon, Monster Hunter, Pokémon, and Digimon. With this power, he is able to utilize various skills and abilities to navigate the treacherous landscape of Inberia, all while avoiding the ultimate fate that awaits him. As Leylin embarks on his perilous journey, he must rely on his wits, cunning, and the borrowed powers of his alternate selves to survive against the forces of destruction that surround him.
