Elder Kuzhu, a thousand years ago, was one in the company of the Cosmic Six Strange, along with Xin Ruyu and Shi Pi the Elder.
Due to his side-branch cultivation technique, he was always unable to comprehend the Great Dao and progress further. His mental flaws also prevented him from purifying his Primordial Spirit to Pure Yang, to become a Heavenly Immortal.
Thus, he turned to Buddhist cultivation techniques, practicing the withered Chan meditation, and every sixty years he would reincarnate in Central Earth to experience the Great Dao amid the mortal dust and accumulate merit and virtue.
The last time he was reborn into a beggar's body, he took it upon himself to help people of the Emei Sect to seek revenge on Shi Feiyang, this "Evil Dragon," at the Outer Heaven Divine Mountain. Not only was his body destroyed, but his state of mind was also ruined by Shi Feiyang, leading to Deviation. His entire body stiffened and turned as stone-like.
