Qi Lanyin

During the Zhenyuan era, the accidental death of the Bai Ze goddess, who governed both human and demon realms, leads to chaos as demon beasts run rampant. Disguised as Zhao Yuanzhou, the demon leader Zhu Yan offers to form a demon-hunting bureau to help restore order. Wen Xiao, suspicious of Zhao Yuanzhou, joins the bureau along with her childhood friend Zhuo Yichen, skilled archer Pei Sijing, and the talented but timid doctor Bai Jiu. Together, they confront the creatures from "The Classic of Mountains and Seas" and uncover the darker truths behind the chaos.

Yun Wei Shan, a spy longing for freedom, infiltrates the palace to complete a mission. Within the eerie and mysterious palace, she encounters love and friendship, embarks on a journey of self-discovery, and finds the determination to move forward. Together with the rebellious nobleman Gong Ziyu, they grow and mature through their shared experiences.

The story starts because of one journey. Seven people who have never met before climb aboard the same ride that goes into a seemingly endless tunnel. Despite the countless trials, corpses that mysteriously appear, past acquaintances that returned from the dead and an unseen danger threatening to swallow them whole, it's as if they are trapped in an enclosed space where there is no escape.
