Arc 16Abyss Invasion of Sea God Island
Xu Xingyu defended Sea God Island from the Abyss invasion until three Supreme Gods sealed the rift, leaving him to prepare for its eventual reopening and a possible continental war. He then sought Electrolux's help with Wang Dong'er's divided soul and agreed to search for the treasures needed to treat her.
- The Spirit Emperor killed Sea Dragon Douluo and prepared an invasion under the Abyssal Sage King's orders to capture the Sea God's inheritor.
- The Abyss Emperors breached Sea God Island's protective array, and Xu Xingyu restored it before fighting the Spirit Emperor and Devil Emperor.
- Xu Xingyu killed the Spirit Emperor, Devil Emperor, and Blaze Emperor, but the Abyssal Sage King emerged and trapped him and Wang Dong'er.
- The God of Destruction, Goddess of Nature, and Xiao Wu sealed the rift, and Xu Xingyu negotiated a share of the Abyss Plane's energy.
- Xiao Wu approved cooperation with the Spirit Contract Pagoda, reconciled with Wang Dong'er, and revealed that Tang San had disappeared from the Divine Realm.
- Xu Xingyu arranged a Spirit Contract Pagoda branch on Sea God Island, returned to the continent, and proposed secretly supporting the Star Luo Empire against the Sun Moon Empire.
- Gu Yuena and Electrolux advised Xu Xingyu that treating Wang Dong'er's conflict with Tang Wutong required separating and purifying the soul fragment.
- Electrolux offered Spirit-Splitting Wood, named two other necessary treasures, and secured Xu Xingyu's help seeking fragments of the Angel Holy Sword.
