After I Transmigrated into a Wang Family Member, I Tricked Wu Xie

I transmigrated into The Grave Robbers' Chronicles as a member of the Wang family. When I opened my eyes, I found myself spying on Wu Xie. In the original story, the Wang family are villains, and Wu Xie eventually wipes them out completely. I immediately decided to switch sides, but I had no System or golden finger. When I first approached Wu Xie, he looked at me coldly. “One of the Wang family? Stay away from me.” I replied quietly, “I can help you take down the Wang family. I know all their bases.” Wu Xie narrowed his eyes, clearly unconvinced. So I told him a secret known only to him and Zhang Qiling.
