As Soon as I Contracted with the Demon Queen, I Was Kicked Out of the Adventure Team.

A hundred years ago, the Abyss invaded Blue Star, and strange fog spread. The world has entered a strange era dominated by human warriors, domain demons, potion science, alchemy, monsters, enchanted weapons... Jiang Yi relied on the Yuanchu Stone Tablet to gain the ability to contract unlimited demons. While others were still relying on armed forces to fight against monsters, Jiang Yi had already harvested various demon servants. Adam, Eve, Taotie, Netherworld, Shadow Demon... The ancient mythical creatures all surrendered to Jiang Yi and sent him to the throne of the abyss. One day, when the real enemy invades, the whole world panics. Only Jiang Yi looked calm: "Look, you are the challenger."
