Heavenly Lightning and Fire

Boom!

The impact formed by the loud bang practically blew down all the trees within a circular area of 328 feet. The powerful qi flow blew everyone off their feet. 

The black fog that was touched by the fire instantly turned into flames that looked like sparks. With one whoosh, they ignited and immediately burned all the air around them. They began spreading outward like fireworks. 

The flames engulfed the forests nearby. 

The trees were immediately lit, and they were quickly scorched black. It was the same for the ground, and even when they were scorched black, the fire was not extinguished until a long time had passed. 

Some of the unlucky assassins from Assassin Hall were touched by the phosphorescent sparks, and they were in so much pain because of it that they rolled around the ground and tried everything in their disposal to extinguish the flames, but it was all in vain.
