Konoha: The thirty-year-old Uchiha lacks motivation.

"Ding, the system has detected that the host's age has reached thirty years old. Confirm activation...?"
......
"No no no no!!!!"
"The system has detected strong feelings of disgust from the host and is now in cooldown mode. It will unlock once all tasks are completed. During the cooldown period, the host's age will be permanently reduced to thirty..."
"??????"
In the second year of Konoha, Uchiha Madara, who was about to leave Konoha, was stopped by a curly-haired man. Uchiha Madara's expression softened.
"Cousin, you don't need to try to persuade me. My mind is made up."
"Cousin, it's good to travel with plenty of money. There's not much I can do to help you, but take these things with you and don't skimp on yourself while you're away from home."
Uchiha Gin handed a storage scroll to the other person and tearfully bid farewell.
Years later, Madara Uchiha, who had just captured the Nine-Tails, was resting when he accidentally opened a scroll given to him by his cousin. He fell into deep thought as he looked at the mountain of gold bricks and several ninja tools he had never seen before.
