The Cunning Cobra Snake.

Warp!

Through the long shadow that was formed of the enormous Devouring Snake that was induced by the green glow of the Green Mist Sea, the dangerous Praying Mantis appeared. 

They may both be shadow domain magicians, but they had different fields of focus. This was like a situation where 2 university students studied engineering, but one focused on civil while the other on electrical engineering.

Clearly, from the scene of the toad being intimidated and fleeing from the attack of the Devouring Cobra, the Cobra had the same power level as the Praying Mantis if not even more.

The Devouring Cobra was startled on seeing the Mantis suddenly appearing. He turned his head without hesitation; with this fellow here, there was no way that he would be allowed to feed on the fish.

Well, he didn't need to feed on the fish, all he needed to do was to protect the fish until his poison did the work on his behalf. 

Hiss!!!
