At the farthest reaches of the East Sea, leaning toward the southeast, beyond the Falling Waterfall, there was a divine mountain in the sea that reached up to Heaven—Tianpeng Mountain. Atop this mountain rested the Lingjiao Immortal Palace.
The Palace Master, Master Chi Zhang, became a True Immortal during the Tang Dynasty and was a contemporary of the three greats from the early Tang: Luo Gongyuan, Ye Fashan, and Zhang Guolao.
By then, he had survived the forty-nine tribulations of an Independent Immortal and had built the Heavenly Immortal Palace at the summit of Tianpeng Mountain.
