They had wanted to spare the Dou Qi Continent from the Evil Race from Beyond the Domain's invasion.
That was why they had sealed the Plane Passage.
They had directly cut off the Evil Race from Beyond the Domain's path to invade the Dou Qi Continent.
Even if it might cause the cultivation conditions of the Dou Qi Continent to regress, they had not hesitated.
After all, compared to being invaded by the Evil Race from Beyond the Domain, this was already an excellent outcome.
Moreover, those Dou Di had not failed to leave behind contingencies.
For instance, Tou She Ancient God's Cave Mansion!
And the other Dou Di Ruins.
Those Dou Di forebears had still left behind the Opportunity to Become Emperor for future generations.
Once the Evil Race from Beyond the Domain retreated and a new Dou Di was born on the Dou Qi Continent,
the Plane Passage could be reopened, restoring the flourishing age of cultivation.
In comparison, the Sky Profound Continent, also a Lower Plane, had suffered far more miserably.
It had not birthed its own Ancestral Realm, had no one to watch over it, and possessed a supreme treasure like the Plane Embryo. It had thus directly fallen into a state of being massively invaded by the Demonic Creatures.
Had the Symbol Ancestor not sacrificed himself and burned away his own existence to seal the Demonic Emperor, the Sky Profound Continent would likely have long become a playground for Demonic Beings.
By then, the Sky Profound Continent would likely have ended up just like the White Dragon Plane.
It would have been completely enslaved by the Evil Race from Beyond the Domain, with every living creature suffering a fate worse than death.
This proved that having someone above you really was important.
