Zheng Yulin is a little transparent player in Onmyoji. He raised his son's liver copy by himself, but he was electrocuted due to improper use of electrical equipment. His soul traveled to another world of cultivation to go on a mission to catch the Yamata-no-Orochi that he accidentally let go.
Surviving in another world allowed him to change himself. The Shikigami Summoning System gave him a golden finger to guide him on how to better improve himself. Finally, he found a golden thigh for him to hug.
