"Ding, the host is detected to be 30 years old, the system is about to start, do you confirm to start..."
......
"No no no no!!!!!!"
"The host's strong dislike is detected, the system enters the cooling down period, and the system can be unlocked by completing the tasks cumulatively. During the cooling down period, the host's age is punished to remain 30 years old..."
"???????"
In the second year of Konoha, Uchiha Madara, who was about to leave Konoha, was stopped by a curly-haired man. Uchiha Madara's face warmed up.
"Cousin, you don't have to persuade me, I'm determined to leave."
"My cousin, you are poor but rich, and there is nothing I can do to help you. Take these things with you, and don't wrong yourself when you go out."
Uchiha Gin stuffed a storage scroll into the other party and said goodbye with tears.
A few years later, Uchiha Madara, who had just captured the Nine-Tails, accidentally opened the scroll given by his cousin during his break. Looking at the piles of gold bricks and several ninja tools he had never seen before, he fell into deep thought.
