It couldn't have lasted until today!
If it were like other universes, where one Great Saint Realm cultivator could devastate an entire domain, the Tunnel World would have ceased to exist countless ages ago.
Thus, at the upper reaches of the river of time, it's said that certain great powers united and worked together to impose laws upon this world.
Even the titans of the ancestral realm are suppressed by these laws upon arriving here.
On the surface, this world appears imperfect—ancestral realm titans are constrained by rules here. It might even seem more advantageous to rule their own universes freely. Yet, in reality, nearly all ancestral realm titans, despite knowing of the Tunnel World's restrictive laws, still wish to come.
Beneath the ancestral realm, endless beings pursue this world with unparalleled fervor!
