The smoke of the Fourth Ninja World War has not yet cleared. Uchiha Itachi, who was reincarnated in the dirty land, used the Mangekyō Sharingan to break free from the shackles, but when he cracked the forbidden technique, he triggered the "Inverse Sky Mysterious Formation" left over from ancient times. When the purple moon blood pupils intersected with the time and space runes, he was actually drawn into the vast aura of the Canghuan Immortal World - there was no chakra, no tailed beasts, only the immortal cultivators who swallowed up the heaven and earth and the great monster that covered the sky and the sun.
Deep in the Jiuyou Mountains where the Hongmeng had just opened, a sloppy old man who called himself the "Ancestor of Honggou" looked at this visitor from another world with his eyes shining brightly: "The soul fire is like glass, and the consciousness is like the sea of stars. This man should be the one to break the catastrophe!" He used the innate purple energy accumulated over thousands of years to reshape Weasel's flesh and blood, and threw the "Nine Transformations of Taixu" in front of the case: "Building the foundation is no more than an ant knocking on the door. If you want to crush time and space and return, you need to become a Hunyuan Sage!"
From the sword tomb trial when he first entered the Immortal Sect, to going to the Hundred Thousand Monster Mountain alone to suppress the nine underworld phoenixes; from the alchemy apprentice who exploded in the alchemy furnace, to the tribulation master who understood the three thousand avenues. When the blood moon demonic tide swept through the fairy world, Itachi stood on the Great Wall with the Immortal Sword of the Ten Directions on his back, and the Eye of Deception (originally written as the Rinnegan) penetrated the nine layers of the sky. At this time, he knew that the true purpose of the ancestor of the Divide for thousands of years was closely related to the ultimate secret of the ninja world...
After thousands of years of cultivating immortality, he finally became a saint, and once he stepped into the void, he returned. When the white-haired Itachi returned to the top of the sacred tree carrying the Law of Annihilation, what Kaguya Otsutsuki saw was not a ninja, but the Hunyuan Sage with chaotic green lotus wrapped around his fingertips: "This time, it's my turn to say - other gods!"
