Each Dao child in the Immortal Manor is backed by a Protector whose strength is at least at the peak of the Nascent Soul Realm. If the Dao child encounters a fatal danger, the Protector will spare no costs to save him.
Even if that means sacrificing their own lives.
This is the realization of being a Protector of the Immortal Gates, as each Protector has already reached the end of his lifespan and has no hope of further breakthroughs.
However, a Dao child is a prodigy of the Immortal Gates who may breakthrough to the Dividing Spirit Realm.
Every time the Immortal Gates gain a Dividing Spirit Realm master, their heritage strengthens. Even if it meant trading ten True Monarchs at the peak of their Nascent Soul Realm, the Immortal Manor would still be willing to obtain a Dividing Spirit Realm master.
But ordinary Protectors are generally reluctant to enter places like the Death Spirit Land.
