What is the prototype of pueraria lobata, the mother of mysteries?

In the era of Nariakira, Ishikawa in Hanoi hated Shimen's wife. She was seriously ill, and his brother Lu Wudaoman told his fortune. He learned that eating the livers of wild foxes living in Shinto (now Osaka Prefecture and Izumi City) in Hequan Prefecture and the whole county can cure them. Ishikawa hated Uemon and sent people to hunt foxes. Born in Abeno, Dongsheng County, Tianjin (now Abeno, Osaka Prefecture), Cai Yi Abe (a legendary figure) was injured while visiting Xintai Forest to save the white fox hunted by hunters. At this moment, a woman who claimed to be Ge Ye appeared, wrapped it up and sent Cai Yi home. Ge Ye and Bao Ming fell in love for a long time, and finally got married and gave birth to their son Tongziwan (Cai Yi's father and county had a conflict with the evil Uemon, and Cai Yi was also harmed by the evil Uemon). When Tongziwan was 5 years old, Ge Ye inadvertently revealed his true colors. It turned out that she was the white fox that Cai Yi had saved.
