"[Iron Wall]!"
Yang Yu's sword stabbed directly, and from He Meng's hand grew a light blue ball, swiftly expanding before her into a wall.
With a quick withdrawal of his sword blade, Yang Yu moved lightly and, in the blink of an eye, appeared on He Meng's right side.
Behind the Iron Wall, He Meng had already turned around, launching eight ping-pong ball-sized blue "Water Balls" from between her fingers, each one like a blue bullet.
Seeing the trajectory of each Water Ball clearly, Yang Yu swung his sword blade, shattering them one by one.
A sound like a balloon explosion echoed, and the shattered Water Balls fell to the ground, turning into a puddle of water, which, as if alive, quickly crawled back to He Meng's side and returned to her hand.
This was Yang Yu's envisioned solution.
