Let's speak of Zhong Nanshan's Jade Pillar Cave.
Under Yuanshi Tianzun, there was a Qi Refiner, known by the Daoist title Yun Zhongzi, who had achieved immortality for hundreds of years, practicing here.
A few years ago, when Daji first arrived in Zhaoge, Yun Zhongzi saw the demon qi piercing the sky over Zhaoge and couldn't bear to see the people suffer at Daji's hands, so he went into the mountains, found an old dead pine tree, cut off a branch, and carved it into a wooden sword to present to King Zhou.
The magic of the immortal family is wondrous and ever-changing. At that time, just with this Pine Wood Sword, Daji's soul was nearly scattered. However, King Zhou favored Daji, believed the demon's lies, and threw the Peach Wood Sword into the fire to burn it.
This is the prologue.
Today, another person came to Zhong Nanshan's Jade Pillar Cave, namely Taiyi Zhenren, a fellow disciple of Yun Zhongzi from the Chan Sect and one of the renowned Twelve Immortal Heads.
