Arc 27Alliance and Realm War
Yang Tianyou helped establish the Four Symbols Alliance and led its campaign against the Demon Sea, where the Blood-Slaying Dao Secret Realm was captured. When realm gates opened, the Nine Phoenix Realm invaded the Lu Wu Realm, but the Water Tribe and Flood Dragon Clan drove its forces back and sealed the gate.
- Yang An'nan killed three siblings on a deserted island and took the resources they had found, while Yang Anping agreed to help him keep killing for cultivation supplies.
- Yang Tianyou brought the Yang Household fleet to Huanghua Island, where its trade flourished, then traveled with Yunhua to Four Symbols Island and gave her an Iron-Eating Beast cub named Yun Bai.
- The Four Symbols Legacy formed an alliance to prepare for an Interface War, and the Yang Household secured a deputy leadership position after yielding resources and connections.
- The Lu Wu Realm Alliance assembled, established a unified Cultivator Legion and other war preparations, then resolved to attack the Demon Sea after tracing the approaching war's cause there.
- Yang Tianyou joined the assault on the Blood-Slaying Dao Secret Realm, where Dao Disciple Yesang and the Cloud-Swallowing Walker opened a breach with Four Symbols Thunder Pearls.
- The alliance forces defeated the Blood-Slaying Dao's defenders, but the Blood-Slaying Dao Master activated a formation that killed everyone in the realm and trapped the survivors in a sea of blood.
- The Eight Desolations Saber Saint purified the secret realm's origin, the major powers divided its territory, and Yang Tianyou obtained blood-soul power for the Blood Moon Secret Realm.
- Thirty years later, realm gates opened across the Lu Wu Realm, and a Nine Phoenix Realm army attacked the Eastern Sea before the Flood Dragon King, Grand Elder, Water Tribe, and Sea Beasts drove it back and sealed the gate.
