Japanese secret forces are raiding tombs in search of Chinese national treasures. Commander Kazuki Yamamoto specializes in the study of Qing dynasty history. He learns that Huang Taiji was buried at the dragon's meridian of Jiulong Mountain to protect his kingdom, so he wants to find the dragon's meridian of the imperial tomb, get the exact location of the tomb, and search for the dragon's meridian of Huang Taiji. However, none of the teams that were sent out came back alive, so he goes to the locals to find out about the situation. The tomb guardians, led by Wu Dahu, have a bad feeling when they learn of this matter and hope to stop Kazuki Yamamoto by using the fraudulent trick of "Lighting Incense to Ask the Corpse". As they are exposed by the traitor, Shen Jun, Wu Dahu plays along with their plan and gets into the tomb with the Japanese, planning to wipe them out. After that, he finds out that Shen Jun is also a tomb guardian. The team of tomb guardians buries the Japanese in the tomb along with their conspiracy by means of the tomb's mechanisms.
