Li Zhirui's luck was good; during his descent, he did not encounter any interference from Outer Realm creatures, and there was nothing around the mountain where he landed that could threaten his safety.
So he was able to immediately guide and summon the Primal Spirit Realm's Heavenly Dao.
But not everyone was so lucky!
As soon as Doumu Lord attacked the boundary membrane, the Outer Realm Heavenly Dao warned and notified the creatures of this realm, urging them to move quickly to stop the invasion.
However, before they could fly to the boundary membrane, Li Zhirui and others had already entered, then immediately scattered in all directions.
So they could only change targets and attack those Spirit Lights falling from the high sky.
Compared to other forces with several Heavenly Immortals and dozens of Earth Immortals, the Spirit Light emanating from the lone Li Zhirui was obviously inconspicuous.
