Martial Soul: I Use Cheats in Douluo

[Fanfiction + Transmigration into a Book + System + Major Rewrite] With a System, I can transmigrate into all kinds of fictional worlds. This time, I end up in a world called Douluo Continent. My new identity is Qian Xunji's adopted son, Qian Renyun, and I've awakened the legendary Triple Martial Souls. “Wait, what?! System, you're telling me to help the protagonist?” “Get lost. I still prefer Bibi Dong... No, I want to be a major villain.” I was born a member of Spirit Hall, and if I die, well, so be it... With Qian Renxue on my left, Hu Liena on my right, and Bibi Dong in my heart, watch me enjoy spicy rabbit head right in front of the protagonist. “You wouldn't want your beloved to stay dead, would you...” The protagonist gets to cheat however he likes? Then you've got a death wish. Take this, Blue Silver Entanglement!
