Xie Zhien

Introduction
The head of the Fire Crow Country's Xie Family. He Yiming met Xie Zhien during his quest to killing a 500-year-old spirit beast. Xie Zhien cultivated two elements at once to the peak of the tenth layer of Houtian Realm. He wanted to break through to the Xiantian Realm using engendering elements (wood and fire) but as his age was above 80, he didn't dare to risk an attempt which could destroy his meridians and ruin his cultivation.

Book 2
Xie Zhien was an alchemist which helped to make gold cores for He Yiming. He Yiming, at the time, wanted to hunt a 500-year-old spirit beast in order to break through to Xiantian but Xie Zhien gave him an epiphany - Xie Zhien talked about another way to break through to Xiantian, by cultivating two engendering elements to the peak of the tenth layer of Houtian, one could try to make these elements come together and make contact with the worldly Qi that only Xiantian's have access to. He Yiming broke through to Xiantian Realm right after learning this information and vowed to help Xie Zhien breakthrough to Xiantian Realm in three years.

Book 3
Two years later, when He Yiming's age reaches 17, he helps Xie Zhien advance to Xiantian Realm in Kai Rong Country during the Xiantian fair.
