Transmigrated into Naruto’s Warring States period, he starts on the brink of death and activates a sign-in System.
While Madara and Hashirama fight a bloody battle, he signs in to receive ten Shadow Techniques. At the Battle of the Valley of the End, he signs in to gain an alternate-dimension fake-death escape. In secret, he watches the Zenin clan migrate west to Iwagakure. Every ten years, their bloodline awakens one inheritor of a Shadow Technique, continuing for six generations.
During the Fourth Shinobi World War, when the Impure World Reincarnation runs wild, he tears open space and descends, suppressing everyone, bringing the era of the ninja villages to an end, and crushing the Otsutsuki.
He lay low for a thousand years, all for this day. From now on, I rule the shinobi world.
