Heavenly Official Secret Technique

Ten years ago, my father disappeared mysteriously, and there was no trace of him for a while... Ten years later, I found a pair of rubbings left by my father with a mysterious silk scroll between them. The ancient words on it guided us to an ancient tomb! Treasures passed down from generation to generation are buried in the Song Dynasty tombs in Baoshan, and the hanging coffins in the Yuan Dynasty imperial tombs are actually empty. We found a parchment scroll with a last chapter in the tomb. What was the opportunity mentioned by the Yuan Dynasty Imperial Master? What kind of story does Baoshan hide with its nine-square grid of strange gates, chain bridge, and gate of life and death? Does the legendary Sky Peeping Mirror really exist?
