Leon was constantly attacking the huge trees. One could imagine the number of kill points she had spent on mana potions by looking at the vials on the grounds. A look of exhaustion filled his face, yet he continued to attack the tree. The tree, which was initially burning red and radiating immense energy to its surrounding snow, was mostly covered in ice and looked dead. Its fire energy and vitality were busy coping up with Leon's attack using ice-sword skills.
Leon had managed to stab the tree around 10 times at various weak spots before the ammunition of his army ran out. He then commanded them to attack the tree directly while he ingested more and more ice energy into the tree. To his surprise though, two things were happening simultaneously. His mana stats were slowly increasing, and so was his sword efficiency.
