Deities are immortal and indestructible, but true indestructibility refers more to the immortality of the Power of Rules, rather than simply becoming a God means being immune to death. Otherwise, throughout the endless time, there wouldn't be so many fallen deities, including many Lower-Rank Gods, Middle Rank Gods, Upper-Rank Gods, and also quite a few Main Gods.
Within the Netherworld, the Master of the Nether River of the five has seen two of them completely disappear from the world, with even their Rules disintegrating.
As for the other three, theoretically, they should have perished in the past.
However, their Power of Rules was not stripped away.
So as time flows, there still exists the possibility of their return from the past.
In fact, not only the Main God.
Including other deities, as long as their Power of Rules is not claimed by someone else, they all have a chance of return.
But clearly, this time the Two Great Empires would not give Osiris any chance.
