The blades fell, and the brains of two zombies were pierced almost simultaneously.
Hidden around the corner, Derek was utterly stunned by the actions of the two men reflected in the mirror.
Initial stalking, mid-stage advancement, late-stage neck binding, neck twisting, decapitation. All actions flowed seamlessly, akin to a precision instrument set to a timer, without any delay, leaving Derek in fear reminiscent of the previous night when Xu Renjie sneaked up on him from behind.
It must be understood, if the other party had had the intent to kill at that time, Derek wouldn't even know how he died; he would be reporting below at Yama Hall to receive his certificate.
Having dealt with the obstructing zombies, Xuan Zhanxiao didn't pause for a moment. After the blade fell, he immediately pulled it out, crouched, and returned.
He then sneaked back to the entrance, lightly tapped Derek's shoulder twice, signaling him to quickly move forward and lead the way.
