In the blink of an eye, Xu Xinrou's body emanated a strange Formation fluctuation.
An impressive Formation Barrier automatically appeared around her.
Seeing this, Xu Yuan's eyes narrowed slightly.
But the next moment,
"Slap—"
The slap still landed solidly.
The crisp sound of a slap was especially clear on the silent and empty official road.
Xu Xinyao's delicate body was sent reeling back two steps by the slap before she managed to steady herself.
Having been slapped for no reason, she didn't cry out immediately.
Xu Yuan looked at his foster sister before him and slowly withdrew his hand:
"Why did you stop the defensive Formation?"
Xu Xinyao looked at Xu Yuan, her beautiful eyes devoid of resentment, her voice soft:
"Formation Rebound, Third Brother, your cultivation is weak, you could get hurt."
Having been struck and still thinking about others, Xu Yuan grinned:
"Aren't you going to ask me why I hit you?"
