Konoha: Thirty-Year-Old Uchiha Can't Be Energetic

"Ding, it has been detected that the host's age has reached thirty years old. The system is about to be turned on. Do you want to confirm that it is turned on..." "NO NO NO NO!!!!!!" "After detecting the host's strong dislike, the system enters a cooldown. It can be unlocked by completing tasks cumulatively. During the cooldown period, the host's age will be kept at thirty years as a penalty..." "???????" In the second year of Konoha, Uchiha Madara was stopped by a curly hair as he was about to leave Konoha. Uchiha Madara's face became warm. "Cousin, you don't have to persuade me, I have already decided to go." "Cousin, my family is poor but my family is rich. There is nothing I can do to help you. You should take these things with you. Don't wrong yourself when you go out." Uchiha Gin handed a storage scroll to 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 a break. He looked at the piles of gold bricks and several ninja tools he had never seen before and fell into deep thought.
