Upon seeing the completely black metal wrist guard in Gu Yunfei's hand, Gu Yanzhou's face showed a trace of confusion. Even now, he did not quite understand what this black metal wrist guard actually was.
"Young master, what is this wrist guard?"
In his words, Gu Yanzhou's tone carried a sense of inquiry. He couldn't figure out why, with this metal wrist guard, capturing Lu Yu could suddenly become so easy.
As he spoke, Gu Shengzhe also cast a questioning look. Clearly, he was equally curious about this black metal wrist guard.
Upon hearing this, Gu Shengzhe smiled slightly and slowly removed the black wrist guard, putting it on his own wrist. He said, "Father, Uncle Zhou, this wrist guard is the latest personal weapon developed in Europe. It can consecutively fire three electric spikes, mainly used for self-defense and dealing with large wild beasts outdoors."
