Xiao Yuan walked over at her words, crouched down, and looked in the direction Xiao Yi Xian was pointing.
It was beneath the chair's seat. There was a groove there, which they had failed to notice while moving the skeleton earlier. The chair's four legs were fixed to the ground and could not be moved.
"It seems to be some kind of mechanical mechanism, not a Dou Qi formation."
After pondering for a moment, Xiao Yuan spoke thoughtfully.
"A mechanical mechanism?"
Xiao Yi Xian had only read a few basic books on mechanisms, so she naturally did not understand them as well as Xiao Yuan. She looked at him in confusion.
"Yes, but this mechanism has probably been sitting here for a long time, so it may not function properly anymore. I'll try it first."
With that, Xiao Yuan released his Soul Strength and carefully sensed the interior of the chair and the ground beneath his feet.
Before long, Xiao Yuan raised his head and looked at Xiao Yi Xian.
"How is it?"
Xiao Yi Xian asked curiously.
"It should still work."
As he spoke, Xiao Yuan pulled out several small tools he had previously collected from the golden-fingered stall owner at the marketplace and began trying to crack the mechanical lock.
Click!
Before long, a crisp sound rang out beside them.
Xiao Yuan then stood up and tried turning the chair.
It would not turn counterclockwise, but it could turn clockwise.
As the chair rotated, the rumble of a massive mechanism operating echoed throughout the stone chamber.
Then, the bluestone strip in front of the chair, upon which the three opened chests had been placed, slowly sank into the ground, revealing a flight of stairs leading downward.
At the same time, a scorching wave of air rushed toward them.
