Taiyi Zhenren (Chinese: 太乙真人; pinyin: Tàiyǐ Zhēnrén) is a character in Chinese folklore. Taiyi (lit. "great 2nd Celestial stem) means "primordial unity of yin and yang" and Zhenren (lit. "true person") is a Daoist term for "Perfected Person". According to the opening of the classical novel Fengshen Bang, he is the reincarnation of the first emperor of the Shang dynasty, Shang Tang.
In Fengshen Bang, Taiyi Zhenren is the renowned teacher of Nezha, the celestial being destined to bring peace back to the Zhou Dynasty. Taiyi Zhenren is stationed atop Mount Champion and instructed Nezha to stay at Old Pond Pass - the place he had been born. After Nezha experienced great trouble with Ao Guang and went fleeing back to him, Taiyi Zhenren would at first be seen in deep thought; Zhenren would soon draw an "invisible juju" along his back however—as to give him a safe passage to heaven through invisibility. After Nezha created further issues with a woman by the name of Madam Rockie, Taiyi Zhenren would soon be seen face to face with her in front of Taiyi Zhenren's cave which Nezha retreated into for protection. After having no choice but to be rid of Madam Rockie, he would start off by disabling the silk scarf which she stole from Nezha, and then trap her within his Nine-dragon-fire-net. While trapped in this net, Taiyi Zhenren summoned several dragons which unleashed a large volley of fire into the net; instantly killing Madam Rockie and turning her back into her original form as a molten rock.
