Li Fei, holding the sword, trembled slightly, staring blankly at the scene before him.
After a few seconds, silence finally descended. He tentatively extended the sword, swinging it through the air. After a few swings, the path before him was clear; the wall of air seemed to have vanished.
He reached out to touch, feeling nothing but empty space ahead. Tentatively, he leaped forward and immediately began to free fall, the sound of the wind whooshing by his ears.
The wall had broken; it was finally broken. He was greatly amazed as his body steadily landed on the ground. Then with another leap, he soared into the air, gliding effortlessly through the sky.
He was terrified, his hands constantly fluttering, afraid of falling, his clumsy body like a bird just learning to fly. Gradually, he landed on the tip of a tree, then tumbled forward, clumsily flying downward.
