In the end, the ancestral return immortal bone chose to admit defeat.
The injuries of the physical body were easy to recover, but the injuries of the soul were difficult to recover. If there were any hidden injuries, it would greatly affect his future achievements.
If one wanted to transcend and step into the immortal Dao, any living being had to go through the immortal tribulation realm.
This realm, as its name suggested, was the Tribulation before becoming an immortal. It was not a single tribulation, but nine.
Only by going through the trials and tribulations could one become an immortal and transcend above.
However, this was too difficult. In this process, every tribulation was extremely dangerous. It could be said to be a dead end. Every tribulation could stop a large number of cultivators, causing them to waste their previous efforts and turn into ashes.
