It was a sharp ringing, the sound wasn't very loud, but it was piercing.
Weilan suddenly tensed, looking towards Lu Hechen.
Lu Hechen's whole body stiffened as well, he said to Weilan, "Someone's broken in, quickly go upstairs."
The moment he finished speaking, he dressed Weilan, quickly putting the taken off clothes back on, then carried Weilan and headed upstairs.
Weilan couldn't care about anything else, Lu Hechen's tense demeanor had already made her realize the danger.
Otherwise, he wouldn't be so tense.
"Who has broken in?" Weilan asked nervously, lowering her voice, "Can you see them?"
"I can," Lu Hechen said in a deep voice, "Go to the upstairs study."
"Okay."
Lu Hechen, carrying Weilan, rushed straight to the upstairs study, opened the door, and closed it.
He took out his phone and turned it on, saying to Weilan, "The computer here can access the entire surveillance feed, and my phone can too; later, I'll install the system on yours as well."
