Arc 65Underworld and Western Plains
Fu Qian helped Lisha investigate the dead underworld, where they uncovered signs of its collapse and killed a bone centipede. He then traveled to Xiyuan in disguise and recruited Hao Ke after confirming a shadow had come there.
- Fu Qian used the paired armchairs to travel between his laboratory and the Half-step Moon, then visited the Sword Participation Institute and discussed the cathedral report with Yuan Fang and the others.
- Fu Qian admitted killing Bai Jinting for opposing grafting and revealed that a high-ranking power had protected him, while Yuan Fang agreed to report the matter discreetly.
- Fu Qian demonstrated his sword strike to Li Weixuan, who gained insight and went into seclusion, then helped Lisha after she cured Lita and her headaches returned.
- Fu Qian and Lisha entered the underworld ruins, where they found signs of withering, a skeletal centipede, and a preserved family whose corpses supported Fu Qian's theory that the underworld had died.
- Fu Qian and Lisha tracked the centipede as it devoured bone spirits and grew, then Fu Qian destroyed it after it formed a malformed head and gathered divinity.
- Lisha gave Fu Qian a sample of Kalaodola's flesh, and Fu Qian used the Messenger and Blood Conquest to travel to the Western Plains in Gorimshaw's appearance.
- Hao Ke trapped Fu Qian in a specially designed pit, but Fu Qian escaped and forced him to explain his suspicions about Xiyuan's unusual peace.
- Fu Qian confirmed that a shadow had come to Xiyuan, and Hao Ke offered to help while Fu Qian noted that the dormant volcano showed no unusual activity.
