I, Chen Qinghe, am a low-end Taoist priest who guards the dilapidated "Qingxu Temple" and is extremely poor. My only "legacy" is an extremely evil "soul-inducing lamp" handed over by my master before his death - the lampshade is neither cloth nor paper, and the tentacles are warm and slightly elastic, and it turns out to be tanned human skin. It is said that it can extradite the lost souls and pry into the secrets of the underworld. However, the oil in the lamp is almost exhausted, and the light is like a bean, flickering with an ominous light. Forced to make a living, I accepted a commission from real estate tycoon Wang Zhenbang: His daughter Wang Xiaoya, who was haunted by evil things, was frightened every night and behaved strangely. Stepping into the luxurious but lifeless "Still Water Bay" villa, when the human skin lantern approached the strange Gumantong beside her pillow, a sudden change occurred! The lantern strangely lit up on its own, and the green light penetrated the wall, reflecting the five mummies in Taoist robes that were sealed alive inside the wall! What's even more creepy is that the human skin on the lampshade twisted like water waves, and the clear face of one of the mummies slowly emerged - that was my uncle, Xuan Chengzi, who had been missing for ten years and had no news at all! I fled back to the Taoist temple in panic. A yellowed old photo accidentally dropped from my master's belongings dragged me deeper into the nightmare: in the photo, there were seven high-spirited young Taoist priests standing side by side with bright smiles. Six faces are clearly distinguishable - me, my uncle Xuan Chengzi, and the five mummies in the wall! But the face of the seventh person was completely covered by a thick blood stain that had dried up and was as dark as dirt... Why did the human skin lantern light up because of Gumantong? Why are the mummies inside the wall wearing Taoist robes? Why was the missing uncle sealed? Who is the seventh person covered in blood?
