Zhao Shan} inherited his grandfather's duty as a tombkeeper in the mountains and took over the yellowed oil paper lantern. My grandfather told me before his death that he must carry a lantern to inspect the ancient tombs every night, and the lantern must not be extinguished. He just regarded it as the old man's obsession. Until one day when I was lazy and forgot to bring a lantern, a shrill cry came from the direction of the ancient tomb at night. The next day, an ancient tomb was dug up and the bones were scattered everywhere.
From then on, Zhao Shan abided by his ancestral precepts, but the lantern began to flicker for no reason. During the flickering, he could always see the armored souls walking out of the tombs and wandering towards the village down the mountain. He made many inquiries and found out that there was an ancient army that was defeated and slaughtered buried in the tomb. The souls of the dead were full of resentment, and the lantern was a magical weapon to suppress them.
