"Go to hell!" The man in black shouted crazily.
A fire dragon flew out of his hand and charged at Shi Letong.
The man in grey shouted, "Be careful!" Then, he cast the water spirit spell, and a water dragon instantly extinguished the fire dragon that was about to surround the youth.
The black-clothed man was furious. He shouted loudly, "Shan Lingfei, you're already heavily injured. Yet, you still have the energy to care about the others?!"
The man cast the fire spirit spell again, splitting it into two. One went to surround the Shi Letong, and the other went towards Shan Lingfei. He said proudly, "Shan Lingfei, you've already cast the water spirit spell once. Can you cast it again? If not, you'll die!"
Shan Lingfei was already heavily injured. Using a spell once drained all the spiritual energy in his body.
He simply didn't have the ability to fight anymore.
