Lin Yun returned to her room, took off the necklace around her neck, and carefully put it away.
Ever since the last attack, Lin Yun had been wearing this feather necklace.
There was an external communication device inside that could allow her to contact the outside world when she was in danger.
After getting to know Blackie, Lin Yun asked Blackie to help install a miniature positioning device inside and connect it to her computer security system.
As long as she was in danger and needed help, she could press the location button and send a distress message to the computer.
The computer's security system would contact the police directly to call the police.
At this moment, Lin Yun could no longer trust anyone. She could only trust herself!
Opening her notebook, Lin Yun planned to see if the white dot had run out again.
