I! the Strongest Sage in the Ninja World

Jingxuan traveled to the world of Naruto and could not refine chakra. So I tried to fuse the spiritual energy with the natural energy alone, and then the physical energy with the natural energy alone. He actually successfully condensed two kinds of energy, named 'Shen Yuan' and 'True Yuan'. Jing Xuan discovered that performing Ninjutsu does not require sealing and is extremely powerful. Moreover, you stay young forever and your lifespan is also increased a lot! This... Can't really be a cultivator, right? It seems that I have developed something that is a bit unbelievable. From then on, the ninja world was shocked! Jiraiya: "Miaomushan is so weak, what Jingxuan masters is the real magic!" Orochimaru: "My research is really naive. What Master Jingxuan masters is the real immortality!" Uchiha Madara: "He is a god!" Immortal of Six Paths: "In front of him, I am completely unworthy of the word 'immortal'!"
