This music box was quite special to his mother.
It had been here for several years. If he remembered correctly, it had been a gift from his dead grandfather. He had given it to He Yan before he had passed away.
Whilst playing with the music box, Jian Yujie opened a small compartment. A USB drive fell out of the music box.
Jian Yujie picked up the USB out of curiosity.
As Jian Yujie was quite curious about the contents of the USB, he inserted it onto another laptop next to him.
After opening the USB, he discovered that there was only a video inside.
However, Jian Yujie was shocked as soon as he saw the contents of the video.
The people that were in the video were Jian Yiling and Jian Yunnao!
They had been quarreling at the top of the stairs. Could it be...
The surveillance video soon came to the scene where Jian Yunnao had fallen down from the stairs.
