Lin Wu witnessed the barriers made by the cultivators cracking due to the opposition of the formation array. The force of the flames was far too much for the weaker cultivators to bear it on their own.
Even if they were equally spread to distribute their spirit Qi evenly, it was simply not enough.
"ARGH!!!" The Qi refining realms cultivators were the first to get killed.
The flames easily devoured them and once one of the links was gone, it easily spread into the rest of the corridor made by the barriers.
~shua~
The flames moved like a tide during a storm and ate everything in its way. No matter which cultivator came in front of it, they were burnt alive. Even the Core condensation realm cultivators did not last longer than a couple of seconds before their defensive techniques and skills failed.
"NOOO!!!!" they couldn't help but wail in pain.
