The legendary grandmaster Zhang Sanfeng had worn a jade pendant shaped like the Taiji symbol since childhood. He knew only that he had had it with him for as long as he could remember, never realizing it was the Taiji Soul Stone, one of the Ten Great Ancient Artifacts. The Taiji Soul Stone allowed cultivators to make twice the progress with half the effort and kept all evil at bay. It had once been a treasured possession worn by the Primordial Heavenly Lord, but had accidentally fallen into the mortal world. When Zhang Sanfeng mastered the Taiji Divine Art, the true energy leaking from his body stirred the Taiji Soul Stone to shine with divine light, alerting the Primordial Heavenly Lord. Delighted, the Primordial Heavenly Lord used magic to retrieve the stone. Unexpectedly, Zhang Sanfeng, who was wearing it, was brought along as well. Rather than being startled, the Primordial Heavenly Lord was even more pleased. Seeing Zhang Sanfeng's extraordinary talent, he took him as his final disciple.
