Elemental Theory

The two new fighters got onto the stage and stayed on either side of the stage. Once the referee gave the go, the man immediately made a fireball in his hand and threw it towards the other man. 

The other man created a veil of a large amount of water that worked as a barrier. The fireball was snuffed out by the water. He then sent a blast of wind towards the other man.

Up on the seating area, Wen Cheng started talking to Alex. 

"You know the elemental theory, right?" Wen Cheng asked.

"The elemental theory?" Alex asked in confusion. "The same one as the one in Alchemy?" he asked. 

"Oh right, you know Alchemy, so you must understand it easily. When two people that use elemental abilities instead of physical fight, if their skill and cultivation base is the same, the one that wins will mostly depend on their element of use." 

Alex felt like he could understand what he was saying but was still generally confused.
