"Sii…"
Seeing all these, Liang Zhenyun became fearful and not just shocked.
To be able to use his toes to draw a line on the ground was already impressive to Wang Yu.
Liang Zhenyun also knew his abilities so he dared to be so arrogant but also because of that, he knew how hard it was to erase that line.
From a scientific point of view, the toes have a small surface area and so had greater pressure while the bottom of the feet had lesser force and hence, lesser pressure. To be able to erase Liang Zhenyun's line, it required at least a few times the amount of strength.
However, when Wang Yu was blocking Liang Zhenyun's attacks, he easily erased the mark on the ground.
To draw the line, Liang Zhenyun had to focus but Wang Yu could erase it while multi-tasking. It was possibly that only Wang Yu and Liang Zhenyun who were there could understand their difference in abilities.
