When Han Yi killed Jixuan Venerable and Yuan Ding Venerable, using the Wan Ming Tome to absorb their Divine Soul Fragments, and with one blow pulverized this palace and this Chaos Space to dust, he fled towards the Ancient Netherworld, preparing to traverse several Dao Domains to return to the Ancestral God Star.
Returning to the Ancestral God Star was done out of caution because he worried that killing two Peak Venerables might provoke retaliation from two Half-step Transcendence Realm Venerables.
Besides,
his arrangements at the Great Wilderness Dao Palace were already well in place. If any issues arose, Nangong Hao could handle them, while Han Yi's presence at the Ancestral God Star would ensure safety. Even Guanghan Realm Venerate or Yutian Realm Venerate would not dare to step into the Ancestral God Star to kill the Ancient Seat of the Taichu Divine Race.
