The attack did not look like Gu Qingcheng's swordlight, which was obviously ridiculously powerful. But that was the good thing about Han Sen's attack; it looked simple, but it left Ancient Devil with no option other than receiving the strike.
Han Sen still didn't know how Ancient Devil had killed Bone Witch. Killing him would prevent him from harming any more of the inhabitants of Han Sen's shelter.
The white donkey Ancient Devil was riding, however, moved and dodged the attack. It made Han Sen freeze.
Han Sen was great at prediction and judgment, and that strike had been set up a string of events that would lead to one singular outcome. It made sure Ancient Devil would have to get hit.
But now the white donkey had broken this. It had subverted his predictions. This was not something Han Sen expected would happen.
