She fled with the mysterious jade bracelet left by her mother, and unexpectedly discovered that there was a spiritual spring space hidden in the jade bracelet - it can stimulate the growth of vegetation, heal injuries and illnesses, and also contains the mysterious notes left by her mother during her lifetime.
