In just 15 seconds of attacking, a section of the second wall was destroyed. Every person in that part of the second wall was killed. And every arrangement around that part of the wall, be they moats, tunnels, underground caverns, traps, and mines, was all destroyed.
The destruction of a section of the second wall caused the three rank 5 formations to deactivate and stop working. After all, they had been using the second wall as their foundation.
So the mobile fortresses were freed from their trapped state and could now continue to battle without being hampered.
The breech in the second wall also rendered it incapable of enhancing the power and defense of the other walls. This reduced the overall power of the Fortifications from 10 times to 9 times the power.
The reduction of the power of the Fortifications could be made up by building and activating buttress walls. But the patriarch of the Red and Blue Fire sect didn't give them the time to do this because he didn't stop there.
