By chance, the protagonist joins an expert in inversion fighting. From an ignorant apprentice who first glimpses the door, under the guidance of his master's words and deeds, he gradually masters various inversion fighting skills, such as the secret of Feng Shui to identify the location of ancient tombs, and the ingenious method of deciphering the hidden weapons in the tombs.
The two masters and apprentices have traveled all over the mountains, forests, and deserts, and those little-known mysterious ancient tombs are their "battlefields."
In the gloomy ancient tomb, fight wits and courage with the machine beast that guards the ancient tomb. The machine beast is huge, with copper skin and iron bones. When it is activated, the sound is loud, and every attack is dangerous. When you encounter an evil spirit with deep resentment, the sinister atmosphere it exudes is creepy, and you will be swallowed up by the resentment if you are not careful.
