Happy Mid-Autumn Festival.
Before Elsa set off, Du You had already started out with a few griffins. The Teleportation Array over in the territory was still under construction; it wouldn't be operational for at least a few more days. Furthermore, a large number of basic structures also needed some time to be completed.
As Du You made his way into the depths of the valley, he spared the Magical Beasts that were only fourth-tier, showing no intention to fight them at all.
Once he entered the uninhabited forest beyond the valley, Du You finally split the griffins up. "Spread out and scout the surroundings, take out any fifth-tier beasts you encounter. If it's one of those that aren't proficient in attacking, beat it half to death first, then leave it at that place."
