History
The ruler of Qin, Qin Shi Huang feared death and searched for a way to live forever. He entrusted Xu Fu with the task of finding the secret of immortality. In 219 a. C., Xu Fu was sent with three thousand virgin boys and girls to retrieve the elixir of life from the immortals, including Anqi Sheng, who supposedly lived on Penglai Mountain in the East Sea. Xu Fu sailed for several years without finding the mountain. In the year 210 a. C., when asked by Qin Shi Huang, Xu Fu claimed that there was a giant sea creature blocking his way, and asked the archers to kill the creature. Qin Shi Huang agreed, and sent archers to kill the giant fish. Xu then set sail again, but never returned from this trip. The Documents of the Great Historian say that he came to a place with "plains and wide swamps" and proclaimed himself king, never to return.

According to the tradition of Saga City, Saga Prefecture, Xu Fu came to the Ariake Sea, where he decided to float a cup on the water and go ashore where he made landfall. As such, the place where he landed the cup is known as "Bubai", which literally means "floating cup".

Xu Fu reached the top of Mount Kinryu, where he met a hermit and obtained the elixir of immortal life. The name of this elixir is Furofuki, and it still grows on Mount Kinryu today. By the way, the name "Furofuki" is said to come from the word "Furofushi", which means "do not grow old, do not die" in Japanese.

In October 2008, the Saga-Xu Fu International Symposium was held in the city of Saga. Many researchers from Japan, China, Taiwan, and South Korea participated and made presentations. A lecture was also given on the relationship with the Yoshinogari site.

Kotaro told him about the Zombie Land Saga Project, knows who Yugiri is and that she is part of the project, when, as seen in previous episodes, zombies are not allowed to give their real names or interacting with others outside of being idols, and he protects her, warning Kotaro to keep his hands off her because he owes her a lot. "And how long have you been talking?" He suggests that he may well have known her in his lifetime, making him at least 150 years old. He is also familiar with Kotaro about the good old days, a trait he doesn't show with girls, considering that he met Yugiri when she was alive, he could be an immortal or a zombie himself.

Yugiri indicates to him that he should continue drinking the tea that he left him so that he can improve and although Xu does not like it, he must drink it to feel better. When Itou kills several Saga rebels, Xu is visibly upset in some unknown way and as he tries to reach the medicine he falls unconscious and is licked by Romero.
