The System Says I'm More Ruthless Than It Is

PS: There is no heroine and no ambiguity. This book kills girls to prove the truth. If you don't like it, don't enter or spray. Traveling through another world, Mo Xiu is bound to the sister-killing certification system... "Are you the system?" A cold voice sounded. Hearing Mo Xiu's voice, the system couldn't help but tremble. "Su, host, I am the system..." "I know, don't talk nonsense, just tell me what's the use of you!" The cold words hit the system's little heart, and the system said tremblingly: "This system is called the sister-killing certification system. The host needs to kill the girl. The more attractive the girl is, the more experience she has. The experience can be used to improve the host's cultivation level." … "Witch, why don't you come over and die quickly..."
