Book-eating Goblin

I found a girl of unknown origin outside; she claims to be a time traveler from a post-apocalyptic era.
Great calamity is imminent, with abominations spreading across the land, human civilization annihilated, and even the world itself shattering, all beyond redemption.
As for myself,
I am considering how to confine this beautiful girl, who has temporarily lost her powers, within my home.

"The Yama Sword is a Magic Artifact passed down from the first generation of the Zhu family," Zhu Shi explained, "Tracing back its origin, it was actually the personal sword of our ancestor Zhu Yi." "The reason this sword's appearance is almost identical to the Evil Sword used by Luoshan Impermanence is that it was the weapon used by Zhu Yi when he was merely an Impermanence. After Zhu Yi became Impermanence, he continued using this very sword instead of replacing it."


"But, this couldn't just be an ordinary Evil Sword, could it?" I asked.


She nodded, "Yes, as its name suggests, the Yama Sword is said to be able to forge Yama."


"The so-called Yama refers to King Yanluo, who rules the underworld," she said. "Since ancient times, the mortal world has been governed openly by ordinary humans, while demon hunters confront the creatures of weirdness hidden among them. If the former's world is called the world of light, then the latter belongs to the world of shadows.
