Liu Liang once again returned to the pile of debris that the robust martial arts school disciple had smashed, and re-watched the entire process of how he was struck and sent flying by the killer.
The killer's movements were very simple, merely taking advantage of the moment the robust disciple hadn't reacted to land a punch right on the chest's vital spot, causing the disciple to fly backwards and crash into the debris, after which he didn't move at all.
Of course, if one were to break down the details, the technique had its intricacies, for instance, how to move the feet, what posture to assume, how to channel force from the ground, and specifically where on the chest to strike...
However, compared to other complex and intricate fighting methods, this punch was relatively simple, or at least Liu Liang felt he could roughly imitate it.
He returned to the entrance once again.
