Wu Xie accidentally received a mysterious package engraved with the pattern of a bronze sacred tree, which triggered the nine-layer code mechanism left by his third uncle thirty years ago. As the bronze secret box was opened, a silk book recording the mysterious palace of King Qin and the secret elixir of longevity was revealed. The Iron Triangle gathered to go deep into the Lishan Mountains and discovered the Yin and Yang Twin Gates in the Millennium-frozen Nine Dragons Altar. The resurrection of the bronze warrior and the mechanism of the Nine Palace Astrology Tray led everyone into the core secret of the First Emperor's Mausoleum - an immortality experiment using living figurines as the carrier, and the legendary longevity pill was actually a taboo product for grafting humans and the Shark tribe.
