Hearing his words her eyes widened.
"Come on, Miss Yara. Say something to your brother." The person on the other side of the phone smiled sinisterly.
Suddenly, a heart-wrenching voice came from the other end of the phone.
"Brother! Please save me..."
"That's enough." The man on the opposite side immediately said, "Just one word is enough. Take her away."
"Yara!" Zack shouted.
However, the other party seemed to want Zack to know that his sister was in their hands, so that Yara would let someone take her away after she made a sound.
"Officer Lu, did you hear your sister's crisp voice? Hahaha!" The other party laughed like a machine. "Now, do you believe that your sister is in our hands?"
"I'm telling you, don't touch my sister!" Zack roared.
