Tang Yu searched through her phone but couldn't find any trace of being located.
It was impossible that someone had logged into her phone ID, because that would not only allow them to locate her but also know her other messages, such as the existence of her child.
Of course, her phone ID had a complex password, and since Ye Sihan wanted to act without leaving any trace, this method was out of the question.
When she couldn't find anything inside, Tang Yu scrutinized the exterior of the phone, even the charging port, but everything seemed normal.
Then she checked where the SIM card was inserted.
Upon pulling out the SIM card, she discovered a black piece smaller than a fingernail and thin affixed to the card.
Could this be the thing that was tracking her location? She remembered that it wasn't there when she first inserted the card.
