There was a lock beside the jade door. Old Master Bai inserted the jade pendant and gently turned it twice.
Gu Yundong heard a click. She thought that the door was about to open. Unexpectedly, Old Master Bai took out the jade pendant again and walked to the other side. He inserted it and turned it twice.
Gu Yundong clicked her tongue. It was really complicated.
With such a complicated mechanism lock, Old Master Bai actually said that the things inside were not valuable?
How many keys do you need to open the door to something valuable?
Before Gu Yundong could finish her thoughts, the jade door in front of him sounded. The next moment, the jade door turned, revealing a path inside.
"Let's go." Old Master Bai led the way in.
Then, Gu Yundong saw him take a deep breath. "Ah, I haven't been in here for two years… Pfft, cough, cough, cough."
Gu Yundong was speechless. She could not laugh. It would seem like she did not respect the old man enough. She had to be calm.
