Resource Battle?

"Here will do." Carroll brought the others to Bloodshed Land's Open Air Combat Training Ground No. 30 and stood opposite Han Xiao. He then moved a long distance away till Han Xiao became a small dot in his eyes.

Han Xiao looked around. This training ground was empty and unobstructed. Around its edges were tall mechanical towers connected by dozens of blue, high-temperature electromagnetic wires. It looked like a futuristic baseball field but many times larger.

The floor was made of gray metal plates. Burn marks left by explosions and slash marks could be seen all around the place, some pits too. Clearly, this training ground was often used.

"In my territory, you have to follow my rules." Carroll's voice came from afar. "First, the battle area is limited to this training ground. If you cause destruction outside of this, you'll bear the consequences. Second, causing severe damage to the opponent is not allowed. So, don't worry, your life won't be in danger."
