Konoha: Simplified Billions of Times, Ninjutsu Is Broken

Traveling to Konoha, I discovered that this world is not as simple and beautiful as imagined. If you want to survive and become stronger, you have to become a ninja, and neither ninjutsu nor physical skills are easy to practice. Fortunately, it is bound to a billion-fold simplified system! All S-level ninjutsu, forbidden arts, and celestial arts have become as easy as drinking water. Metkai: "Li Fan, why do you only need to kick your legs and take a walk to practice Eight Door Dunjia?" Golden Flash: "The second-generation Flying Thunder God is not easy to learn. Hey, Li Fan, were you the second-level Flying Thunder God just now!" Uchiha Madara: "Li Fan, how did you get the Eternal Mangekyō Sharingan, and why is it stronger than mine!" Senju Hashirama: "Shocked! Why does your kid have more chakra than me!?"
