After her grandfather's death, Bai Hanyun was disowned by her parents and cast out of the Bai family. With nowhere else to go, she left the city and returned to the countryside. There, by a twist of fate, she discovered an antique mirror hidden in the basement of her newly purchased home. From that moment on, strange events began to unfold—until one day, she stumbled upon a prayer from a young general.Feng Xiyan, besieged by the Yuezhi Tribe and betrayed by the imperial court, had been driven into a desperate corner. With no access to water, food, or medicine, he and the citizens of Xiqiang City could do nothing but await death. But just as all hope seemed lost, Heaven intervened. From that moment on, the Feng Army and the people of Xiqiang City had enough food and water, living lives more prosperous than even the Emperor himself.

Fu Qian gracefully removed his skull, as if a gentleman were taking off his hat to pay respects.…Everything began with a transcended-dimension invitation.It’s a story of a high-quality Thug turning the impossible into the possible.Of course, on that day, the great being behind the invitation was still unaware of what it had done.

I was just your average burnout. Now I’m a kobold in a dungeon where everything wants to eat me—and frankly, I get it. I look delicious.Reincarnated as the weakest possible monster in the worst possible place, I start with nothing but panic, backward knees, and a skill called Civilization Mimicry—which is sealed. Because of course it is.But survival isn't the story.This is the story of what comes after.Of finding meaning in the scraps. Of building law from ashes. Of kindling memory in a place designed to erase.Because even if the world sees kobolds as nothing, I’ve seen what we used to be.And I’m going to bring it back.Firelight by firelight. Burial by burial. One fragile tradition at a time.Because if the world wants kobolds to be nothing?Then I’ll teach it what nothing becomes when it learns to dream.
