Tomb Robber: I Dressed up as Wu Xie's Short-Lived Sister

[Stealing fan fiction➕Female disguised as a man➕The heroine has no cp➕Group favorite] My name is Wu You, and I am Wu Xie's half-sister. He has lived abroad with his parents since he was a child, and is not often known to people. Since I was born, I have been told that I will be short-lived and will not survive until the age of 18. In order to save his life, he had no choice but to listen to Qi Tiezui's words I declare to the outside world that I am a boy, and I dress like a boy every day. The purpose is to confuse the audience and make it unclear when black and white are impermanent and life-threatening. In the end, I lived to the age of 18 safely, and it wasn't Qi Tiezui's method that worked. But there is a stupid system behind me... With my sweet words and good intentions, he bought me 20 years of life. Of course, this is not for nothing, the price is that I have to help it go to the tomb to find energy stones. Then he will give me corresponding rewards. These 20 years of life are the salary I predicted in advance... Lightning protection: The heroine has memories of past lives, but she doesn't know that this is the world of stolen pens! ! !
