Douluo Dalu: Qian Renxue's Demon King Guard, I'm on a Killing Spree

Qian Renxue has four major flaws: One: She places personal feelings above her position! Two: She is weak in the face of setbacks! Three: She is indecisive and lacks ruthlessness! Four: She lives according to other people's expectations and lacks a sense of self! But I, her protected by the Demon King, am completely different! I, Qian Sha Yu, am merciless, fearless, and without regrets, therefore I am invincible! The trials Qian Renxue cannot overcome, I will overcome. The people she does not dare to kill, I will kill. The matters she does not dare to handle, I will handle! In other words, anything Qian Renxue can control, I will control, and anything Qian Renxue cannot control, I will control even more! Qian Renxue, I was forced into certain things for reasons beyond my control, yet you have resented me to this day... You lost your father, but you still have me. I can completely become the guide of your life, can't I?
