Amon had seen the boy's attempt to attack as he approached. He was ready for it.
Before Lin Can's fist hit, the explosive wind produced by his punch had arrived first. Yet, the wind just brushed through Amon. When Lin Can's fist came, his fist went through Amon as if Amon was made of air.
Lin Fen was not the only one with movement art. Inside the library Amon had acquired from the pyramid legacy, there were also many books containing movement arts. Amon had picked one for learning. He had not used this art till now because it was not a movement art that was suitable for a long race like Lin Fen's one. It was an art that gave a short movement boost for a brief instant.
The movement art that Amon learned was called Lingering Shade Stride. The art made his body lighter as well as gave him a dash of speed for a short period. When he executed this art, it also produced a flash of afterimage.
What Lin Can's fist hit was that afterimage.
