Naruto: This Uchiha Is Too Kind

Lin Ming got lucky, in a physical sense, and was sent to the world of Naruto. The "construction system" awakens at the beginning. As long as you create items and create beneficial value for others, you can become stronger. Ding dong! Help the old lady cross the street and get 1 point of steel shuriken fragments! Collect 10 points to exchange for a steel shuriken. Ding dong! Change the ending of Jiraiya's death and get a pair of Mangekyō Sharingan! Abilities can be stacked! A few years later, when facing Kaguya, the ancestor of chakra, Lin Ming smiled awkwardly because the task given to him by the system was... "Take Kaguya into the harem and prevent the annihilation of the Ninja World. Mission reward: Become the Lord of the Ninja World." System, are you serious? What if I don't do it?
