Naruto from modern times accidentally traveled to the world of Naruto, but was bound to a cheating system - want to redeem his abilities? Yes, you can exchange it for your lifespan. At the beginning, the system defrauded him of five years of his life. Naruto could only struggle to survive while exploring the secrets of the system.
On the surface, he is a "distant relative of the whirlpool" with an ambiguous identity, but secretly he hides the secret of the time traveler. What's more terrible is that when the system is dormant, it must rely on "bond energy" to recover - the stronger the emotional connection with the people around him, the faster his lifespan will be. As a result, he was forced to get involved in the vortex of the three wars, becoming companions with the young Obito and Lin, and even intersecting with Minato, Tsunade and others.
During the crisis at Kannabi Bridge, he used his lifespan to exchange power to save his companions, but found that the shadow of the Inter-dimensional Observation Bureau was hidden behind the system; during the adventure in the snake cave, he saw the remains of other "system holders" and realized that he was not the only one who traveled through it; in the undercurrent of Uchiha, he formed an alliance with Shisui, who also came from the future, in an attempt to prevent the tragedy of genocide, but was involved in the conspiracy of Danzo and Iwagakure...
When the truth of the system gradually emerges, and when the identity of the time traveler may be exposed at any time, Naruto must make a choice between the cost of consuming his life and the belief in protecting the people he cherishes. This is a story about growth, bonding and resistance - even if the system wants to drain his life, he will use the remaining time to rewrite the regretful past.
