Although both the commander of the Undead Tribe and the leader of the monsters perished, the Undead Tribe, now on the right track, no longer 'needed to listen to a dog bark'... these were the concluding words of the 'Old Age Striking King'.
So this battle ended with a decisive victory for the Undead Tribe.
Those Decaying Angels couldn't cause them much trouble again... If that leader over Level 30 hadn't been completely torn apart by hundreds of space dragons, it might have had some tricks, as this creature was actually an Abyss-banished Half-Demon, and above Level 30, it would certainly have some unique Abyssal Spells.
But judging by its sneaky behavior hidden among the monster horde, it probably had those backstabbing moves... Unfortunately, it was caught by Snow Old Dog before it could even use them.
