Anger!
Zuo Cao was truly furious! Having defended the Demon Sealing Tower for so many years, he knew all too well what it meant for Grandmaster Level Demonfolk to infiltrate this place.
It indicated one thing: there was a mole within the Demon-Subduing Division, and not just any ordinary mole.
Otherwise, several Grandmaster Level Demonfolk would absolutely not have been able to approach the Demon Sealing Tower without making any noise.
Because inside the Demon Sealing Tower, there was a Demon Revealing Mirror.
In other areas of the Demon-Subduing Division, there were corresponding surveillance measures.
Even though they weren't as powerful as the Demon Revealing Mirror, they would still trigger an alarm if Demonfolk infiltrated.
No alarm was set off. That could only mean that someone had made preparations in advance.
"Make it quick, take them all out," a cold voice rang in his ear. Zuo Cao nodded, and his attacks became even fiercer.
