When the time traveler Lin Yue became Konoha Genin Umino Iruka, the cold mechanical sound of the "Strongest Mentor System" broke the iron law of the ninja world:
"Accept disciples and cultivate talents, and obtain growth rewards. The ultimate goal: to cultivate disciples who will change the structure of the ninja world and assist the host to unify the world."
The amount of chakra is doubled, the immortal body is transformed, and the power of the six paths is unlocked... The system directly transforms the results of talent cultivation into strength, and Iruka's "classroom" will eventually become the starting point for subverting the order of the ninja world.
