Every human on Earth was transformed into a summoned monster and was summoned to another world. Every summoned monster only had one life and was gifted with ability right from the start. The abilities ranged from Wind Blade to Fireball, Ice Arrow, Guardian Shield, Heal, Illusion, and so forth. Li Xuan was also summoned to another world, but his ability was the Unlimited Revive System. Whenever he revived once, he would get another ability.
