Wan Chu'er observed the surroundings in the dim light before reaching out to touch the wood on the very top.
Wood fuels fire, fire creates earth, earth births metal, metal yields water, water nourishes wood.
The Yin-Yang and Five Elements are ancient Eastern wisdom, profound in their variations and broad in application, beyond what words can express.
In such a desolate mountainous area, the appearance of a mechanism based on the changes of the Five Elements excited Wan Chu'er immensely.
She fiddled with it for a while before managing to pull all five stones out, revealing a small hole under each. Feeling inside, each contained a metal button, and she could even feel graphical shapes on the metal, corresponding to the shapes of the respective Five Elements.
Quietly, Wan Chu'er pressed the five buttons in sequence, then held her breath and assumed a defensive posture ready to attack, just in case the three kidnappers outside awoke to any noise.
