Following that attack, there was a massive drop in the Qiao family's combat capability. From their initial Rank 3 strength, what they could draw out from these injured beasts was probably just the strength of a couple of Rank 2 beasts.
It took just moments for the four demonic appraisers to reveal their hands and overpower the Qiao family and their guests.
As mentioned, these demonic appraisers were prone to using discreet spells and rarely fought anyone head-on. Their greatest reliance was on underhanded tricks.
At first, the Qiao family had gathered so many experts just so they could overwhelm the enemy with numerical superiority. However, with just a few despicable tricks by these demonic appraisers, most of the guests were frightened off. With the Qiao family's forces weakened, these demonic appraisers used shocking attacks to diminish the strength of their strongest pet beasts in order to secure their victory.
