Eight years later.
The door opened and two pairs of footsteps slowly trotted inside. They were extremely quiet as they approached the couple sleeping on the bed. There was complete darkness.
The intruders looked at each other and nodded as they evilly smiled. One of them brought a box and held in his hand. They slowly walked up to the edge of the bed and stood straight.
One of them raised his hand and put three fingers out as countdown.
Three.
Two.
One.
They were just about to press the button when the man on the bed suddenly caught his hand. They froze and looked at him. That man's eyes weren't even open as he caught them.
They looked at each other in panic.
"Liang. Luan." The man said with a warning. "Don't play pranks on your parents so early in the morning."
Bai Li switched on the lamp light and looked sideways at his eight-year-old son, Liang and five-year-old daughter, Luan.
