I Can’t Awaken a Superpower, Yet I’ve Started Using Ninjutsu

[Urban + mythical beasts + Naruto + no simping + invincible] Mythical beasts are wreaking havoc across Blue Star. Humanity can only fight back by awakening supernatural abilities. But Jiang Lu, who transmigrated here, reached the age of awakening without gaining any powers and became a useless nobody in everyone’s eyes. Fortunately, the day before the college entrance exam, the chakra System appeared. Killing mythical beasts earned him chakra, which he could spend to enter the System’s prize wheel, buy all kinds of ninja tools in the System’s shop, unlock and upgrade ninjutsu, and much more... Jiang Lu: “Chakra, unlock a high-level forbidden jutsu for me!” System: “...” Spend 1,000 chakra to unlock the A-rank jutsu Chidori! Spend 10,000 chakra to unlock the ultimate forbidden technique, Eight Gates Released Formation! Spend 100,000 chakra to unlock the ultimate technique, Super Shinra Tensei! Jiang Lu is feeling pretty full of himself now. Supernatural abilities? What a load of crap. S-rank? SS-rank? Even SSS-rank? Who cares? I’m going to become a being on the level of the Sage of Six Paths!!!
