Seriously? I’ve reached Jōnin level, and the system’s only shows up? Novel

After nineteen years navigating the Naruto world and enduring the Second Great Ninja War's devastation, the protagonist faces the impending Third Great Ninja War—only for the system to finally awaken. Armed with the power to awaken the Reincarnation Eye, he becomes the hidden mastermind pulling the strings of the ninja world. This is a translation of the original work 觉醒转生眼，做忍界的幕后黑手.
