In order to prevent people who knew him from finding it too shocking to see his suddenly skyrocketing height, Qin Yuesheng utilized the method from the Profound Celestial Treasure Mirror to control his body's bones, maximizing their interlocking to minimize gaps and achieve the effect of becoming shorter.
