Struggle

"Grand Burst."

The fire created a chain of explosions in a fan-shaped area, hitting all the monsters on the way and creating a wall of flame that would cover their movement for a few seconds until the Magic Power ran out. 

"Good. Let's go." Theo nodded as he and his clone went inside the forest. 

Alea caught up with them and ran through the forest like back in the Dense Forest, where she matched his movement perfectly. Their synergy looked like a couple that had been married for years. 

"By the way, are you not afraid of burning the forest?" Theo asked.

"Not really. I think you've misunderstood something. There is something different between the fire from a Fire Skill and natural fire. The former requires our Magic Power to burn while the latter needs oxygen." Alea explained why she didn't worry about her fire. 

"So, as long as the Magic Power that you pumped out to release that skill became empty, it would just vanish?"
