When I Traveled Through Time and Cultivated Immortality, the System Gave Me a Ninjutsu Progress Bar.

Is it reasonable to practice ninjutsu in the world of immortality? Bai Yichun traveled through the world of cultivating immortals, bound to the cheating system, and what was loaded was the ninjutsu progress bar. After finally collecting several versions of fireball jutsu to max out the powerful fireball ninjutsu, he discovered that there was a hidden item - Madara's top quality fireball, but as soon as he entered the dungeon, he was blasted out of the battlefield by the aftermath. Through Naruto's shadow clone training copy and looking at the shuriken "magic weapon", he was confused at that moment. Fuuma shuriken refining blueprint, Zabuza sword, legendary magic weapon - Mizukage Seven Ninja Sword, are you kidding me? ! You can also make alchemy and weapon refining! The nine-tails bloodline has progressed by 1%. The Beast Control Sect can actually breed tailed beasts. Is the nine-tails the Nascent Soul Demon Emperor? The Ten Tails, the Chakra Sacred Tree, the Chakra Fruit... The Otsutsuki clan is probably not a cultivating family. Then wouldn't he be able to ascend to immortality with the Ten-Tails Jinchuuriki? From then on, he established a ninja sect, recruited disciples, collected tailed beasts, and reverse-refined the sacred tree... Each and every huge plan to ascend to immortality gradually took shape in Bai Yichun's hands. Can he, this devil from outside the world, finally find his way home?
