The dragon breath sword that Xiao Lin had treated as a sure-kill technique all along failed for the first time. He understood that dragon breath was not omnipotent, despite its high levels of power. The special sword aura allowed him to wield power that was several times stronger than his own ability, but it was still nothing to someone truly at a high level.
However, the elf was definitely not someone at that level. At least, she was not before her transformation.
More accurately, even after transforming, Xiao Lin did not feel like she was strong to any extreme degree. Even so, she perfectly countered his dragon breath sword.
Xiao Lin noticed a faint green shield appear around her, and believed that was what blocked his sword aura. The energy shield quickly disappeared, not giving Xiao Lin enough time to observe it.
