Gu Changsheng, a junior mountain-guard disciple of the Qiankun Dao Sect, grafted hundred fruits in the back mountain and cultivated the Chaos World Tree. The immortal-cultivating coalition attacked the mountain gate to seize the treasure, but their devastating offensive could only blow down apples from the orchard. Relying on the Wood-element barrier and healing divine light of the World Tree, Gu Changsheng defused hostility without fighting. Subsequently, the demonic path and the heavenly court successively invaded; he guarded one tree to protect a realm, resolved slaughter with vitality, and interpreted the Great Dao of guardianship and inclusion.
