Stakeout

"What should we do next?" Feng Zi asked Zhang Heng after he sent the email.

"Give me your bracelet."

"Hmm?"

Although Feng Zi was a little puzzled, she still took off her bracelet and handed it to Zhang Heng. He then put her bracelet on his wrist, right next to his. It was close enough for the signal blocker to cover both bracelets. 

"Let's find a safe place first," said Zhang Heng.

"Okay, uhh... we can go back to my house or my sister's house," Feng Zi suggested after thinking for a bit.

"No. Your ID is already in their possession, which also means that they have all your information. In other words, you can't go back to your home, your sister's house, or your colleague's and friends' place. Besides…" Zhang Heng paused.

"...it's you. Not us. I still have things to do. I'm going to send you over first."
