Treason

The signal that Rudra had decided to alert the rebel forces inside was to use haze potions and cover the entire attacking army in thick haze making it impossible for the enemy to get a clear view of what was going on beneath the walls , however the problem was that the demon generals were demanding actions from the humans that were not being executed promptly. 

" What the f*** is shakuni doing man , he is going to get us all killed ". 

" Is he even going to ever give a signal , or is it all a hoax? " 

" Damnit that scary demon general is screaming at me , i got to start attacking or he will gouge my eyes out ". 

" Damnit, i say fu** the signal , lets start attacking the demons right away ". 

However right at this moment , the elites had crossed the 500 meter line from the wall and Rudra gave the command to unleash the haze potions.
