"There seems to be only one key to the Luban mechanism lock. If it can't be opened, then it can't be opened…" Ye Wangchuan looked at her in surprise.
Qiao Nian raised her eyebrows and showed him the keyhole. "Do you think it looks like the Ji family's Patriarch's emblem?"
Ye Wangchuan restrained himself and seriously took a look. He realized that the keyhole's strange shape was indeed very similar to the shape of the Ji family Patriarch's family emblem Qiao Nian showed him before. Then, he connected it to the fact that the owner of the box was Ji Qing, and everything made sense…
He returned the box to the girl and asked in a low voice, "Where did you put the Patriarch's emblem? I'll get Gu San to bring it over for you."
