Prequel to Jigong: the Tenth Bhikkhu Monk

A soul has gone through ten reincarnations for four hundred years from the Sui and Tang Dynasties to the Southern Song Dynasty, and traveled through the most glorious and turbulent periods of Chinese Buddhism in ten different identities. Finally, in the eleventh life, it became the physical body of Li Xiuyuan, the subduing dragon Arhat. So I would like to ask, since this body was given to Dragon Subduing Arhat, where did his original soul Li Xiuyuan go?
