Chapter 583, Dragon Crystal 45 (Brothers, Happy National Day)

The fortress that was bustling just a moment ago is now desolate and empty.

The skeletons left outside have turned into ash.

Leaving behind all sorts of armor and weapons scattered around.

Skeleton Hero hid within the Stone Castle, looking up at the Bone Dragons circling in the sky.

How can we fight this?

Not to mention that the fortress is short on troops now, even when the forces were not reassigned.

It's doubtful that we could have withstood so many Bone Dragons anyway.

Damn it!

Since when did the Blood Clan acquire such formidable strength?

"Go, find the right moment to man the ballistae and shoot down those Bone Dragons," Skeleton Hero ordered the Undead standing beside him.

There were still some Undead hidden within the surrounding buildings.

Upon hearing the Hero's orders,

a squad of Undead immediately seized the opportunity to dash out from a passageway on one side.

Heading straight for the anti-aircraft ballistae on the city walls.
