Return to Raven Rift Valley?
The two Evil Split Crow Gods won't be going back.
The void fissure is a one-way passage, once through, returning means flying back honestly.
Because returning is too troublesome, Evil Split Crow Gods generally don't go back unless summoned by an emperor-level Evil Split Crow God.
The hole Xiaoruan dug is too small for the massive body of the Evil Split Crow God to fit through.
The two Evil Split Crow Gods have to dig by themselves, but the efficiency is slow, after all, Evil Split Crow Gods are flying pet beasts, and digging is not their forte.
While digging, the two Evil Split Crow Gods also realized their efficiency was too slow.
Digging together, being too close inevitably led to bumps and collisions.
The bumps and collisions didn't hurt them, but they affected the efficiency of digging.
Digging separately was no faster than digging together.
