On the southeastern mid-mountain slope of Jade Spring Mountain, there is a cliff with a vertical drop of seventy to eighty meters.
At the open space below, a group of men in grey short-sleeved clothes were bustling around.
Some were digging foundations, others erecting wooden stakes, carving doors and windows, or building walls.
On the cliffside, about five to six meters above the ground, caves of various sizes had been hewn, connected by stone steps a meter wide.
Within the widest cave at the topmost layer.
"Junior Brother Chen?" Zhu Yi looked Chen Mu up and down.
He was in his forties, with a square face, thick eyebrows, and an air of sternness about him. He was the new Pavilion Master of the Administrative Affairs Institute of Jade Spring Mountain, Chen Mu's future boss.
"I've seen Pavilion Master Zhu." Chen Mu greeted him with a respectful fist clasped.
"Which Alchemy Jade Slip are you studying?" Zhu Yi asked.
