The palace does not refer to the Reincarnation Hall.
Each of the three Main Gods holds part of the supreme treasure Reincarnation Hall, which prevents any of them from completely refining it.
It's like a big company with three competing factions.
Each Main God has developed their own forces.
Under the Transit Main God, there are two of the Ten Hall Masters and two strong individuals at the Holy King Tier who pledge allegiance.
There are countless other Holy Tier individuals, either loyal directly or aligned with his faction due to interests.
The other two Main Gods have comparable strength.
The strongest of them wields the authority of "Reincarnation" and commands four of the Ten Hall Masters, leaving only the last two Hall Masters unaffiliated.
They are deeply hidden.
Those Ten Directions Hall Masters, though not wielding any authority, possess relatively high permissions within the Reincarnation Hall.
