I, Baili Yuxiang, am the only remaining avenger in this world. I will stand proudly in this world, let those who have returned me favors fall at my feet and lick them, and make everyone in this world fear me and dare not approach me. My job is to get the person my client hates to receive the punishment my client desires. And my client wants to give me his freedom in this life in exchange, become my loyal dog, complete the mission I gave you, and become the indispensable help behind me.
