Leng Qianchen disappeared near the manor, and the person who caused him such harm couldn't find him, which inevitably led them to think of Grape Manor.
If they were to investigate...
Quan Jinbei was aware of her concerns, but he didn't share them.
"The security level of Quan Family's manor is very high; ordinary people can't break in," he said.
"Even if someone did force their way in, there's no guarantee they could get out."
"Really?" Shi Yaoguang was somewhat surprised; she hadn't noticed that the unremarkable Grape Manor actually hid such devious traps.
Quan Jinbei explained, "The Quan Family's business spans all directions, and every manor, besides its apparent purposes, could possibly be converted into an experimental laboratory."
"Even if there wasn't such an intention initially, there would eventually come a day when it would be needed. The design of the manor takes this into account, as a precaution."
Shi Yaoguang nodded, "I understand now."
