Qingzhu Peak.
Inside the cave mansion, Qinghuangzi wore a serious expression, explaining the general situation of his family's heritage to Ning Zhuo before the divine statue.
Empty Valley Sound Green Mechanism Tube!
This is the name of this mechanism inheritance.
The original source was the Bamboo Mountain Sect.
This sect no longer exists; at the time, the main mountain gate was attacked, the enemy's methods were extremely clever, inciting internal strife within the sect, avoiding engagement and fleeing, abandoning a few cultivators loyal to the sect who preferred to die fighting.
The number of cultivators was too small, and the defense line was broken all the way, ultimately retreating into the bamboo forest in the valley.
At the critical moment, among the surviving cultivators, there were two individuals, one adept in sound rhythm and the other skilled at mechanisms, who cooperated to quickly renovate the bamboo forest, transforming a section of bamboo into a sound whistle.
