I Just Killed the Demon King, but My Brother Showed Me His Health Bar?

In his previous life, after Qin Mu and his teammates killed the Demon King, the brothers collectively showed him their health bars. Best friend: "Brother Mu, I don't want to go back to the countryside. I finally defeated the devil. I want to enjoy it. Let's go together." The female priest who loves him deeply: "Brother Mu, please come with us. From now on, the Demon King's City will belong to us, and we can enjoy everything!" All teammates extended their hands to Qin Mu, who was an absolute core player, and sincerely invited him to enjoy the fruits of victory together. However, in the face of all this, Qin Mu's thoughts were confused, and he finally went crazy and killed all the brothers who wanted to make him the devil! However, after Qin Mu finished all this and returned to the Justice League, the Justice League was afraid of his terrifying power and plotted against him step by step. In the end, he died desolately and alone on a cold snowy night. Open your eyes again. Qin Mu returned to the night when he killed the Demon King, and his best friends reached out to him again. Looking at the expectant best friends and the female priest with loving eyes, Qin Mu's eyes were blood red and he gritted his teeth and smiled ferociously. "My brother's health bar is already high, how can I be a good person?" "You start a group, I have to follow you immediately!" As he finished speaking, the blood bar above Qin Mu's head lit up. In this life... I would rather betray the world than let the world betray me!
