The Summoner Who Saves the Heavens

Mysterious existence: "Go, Saonian! You will travel through a world threatened by evil forces and gloriously complete the mission of saving the world." "How's it going? I feel honored!" "What? You're not happy anymore? It's not up to you. Come over here!" The lucky guy who only had time to shake his head was forced to embark on the road to save the world. Many years later. "I am the legion and I am the salvation! Tremble, devil! Your doom has come!" The intensity of the initial world will not be too high, similar to the low-intensity magical world of Lord of the Rings. The later world is World of Warcraft, with demigods running around everywhere and Titans forcing their way into the planet.
