Conquest of the Otherworld: from the Founding of Hogwarts

In 2026, Blue Planet was attacked by monsters from another world. Lin En, who was originally middle-aged, was forced to join the ranks of defending his country. Unfortunately, he was killed in an orc raid. When he woke up, he came to England 20 years ago. Reborn as Andres Mori with a complete set of golden fingers, he had a chance to save Blue Planet. Until many years later, he not only saved mankind but also led mankind to conquer the other world. He was called by humans: Marquis of Paradise Island, founder of Hogwarts, guardian of mankind, conqueror of the other world, and great magician.
