"Take a look at the structure of the Duke of Devonshire's family."
As Cheng Fei'er spoke, she spread the blueprint on the coffee table.
"This is a rough blueprint drawn by the businessman from our country, it's based on his memory and the information collected by the members of our security team."
Ye Feng followed her movements and looked over. He saw that the floor plan had clearly marked the defensive situation around the manor of the Duke of Devonshire.
"The Duke of Devonshire's family is different from the other Duke's families. Their security is very tight." Cheng Fei'er also told him.
"First of all, they've set up at least twenty sets of ultra-high-definition surveillance cameras at the gate and around the outer walls of the manor. They're also equipped with high-voltage power grids, which almost cut off the possibility of others climbing over the walls."
