As soon as I opened my eyes, I became the substitute of Prince Zhenxi. The original main meridian was blocked, enemies were everywhere, and he was hunted down at the beginning. Fortunately, I have a tortoise shell - others have been practicing hard for thirty years, but I can deduce everything by taking a pill. Innate skills? Complete it as you go. Seven sword sects? Crush with one sword. The princess taught me how to practice martial arts, and the world is waiting for me to become a god. In this life, the fake prince wants to be the best in the world.
