At night.
Huo Yao saw the newly installed security system at the entrance and the infrared scanners on the walls when she came home and raised her eyebrow. That was fast.
After entering the house, she stood at the entrance in front of the system and tapped on the screen.
Huo Jinyan walked up to her when he realized that his daughter was looking at the security system. "I forgot to tell you that two guys came to re-install our security system today."
"Uh huh." Huo Yao pulled her hand back.
"It can do much more than the security system I installed, but there are some features I'm unsure about," said Huo Jinyan a bit sadly.
The technicians had only taught him the basic functions. Despite spending all afternoon trying to figure out how to use the other details, he failed to grasp it fully.
Huo Yao raised her brow. "Let's go in. I'll teach you."
"Okay."
