While both are lords of the same name, Lin Yu's luck seems a bit too good. His cheat ability draws only "forbidden races" that are said to have destroyed the world, and they are all women and all "villains".

The game starts with the [Fallen Angel Reincarnation Pool], which yields only yandere, bloodthirsty older sister characters; followed by the [Pain Witch], [Deep Sea Siren], and [Fallen Angel]. These units are beautiful and powerful, but their personalities are twisted, filled with destructive desires, and extremely difficult to control.

Lin Yu must constantly feign absolute strength and ruthlessness to suppress his "yandere" subordinates. To outsiders, Lin Yu is the great demon king who rules the demon cave, a traitor to humanity. But Lin Yu doesn't care; he only wants to survive.

He discovered that while these "evil female" soldiers were dangerous, they were the sharpest blades if you could conquer them. While the so-called righteous factions (angels and paladins) still valued chivalry, Lin Yu's evil female legion had already won the war by using poison, ambushes, and mind control—leaving no stone unturned.
