Naruto: Tsunade Has so Many Children That They Can Unify the Ninja World

When he woke up, Tsunade, one of the legendary three ninjas, was bound to a system called [Many Children, Many Blessings]! The system has a unique style of painting and a lot of flirtatious words: "Dear, do you want to revive the glory of the Senju clan in the forest? Do you want your bloodline to spread throughout the ninja world and your descendants to become famous? Then give birth! The host is guaranteed to produce two per day, with no upper limit. The more children you have, the greater the reward will be!" Tsunade: (╯‵□′)╯┻━┻ I am a medical master, and I will lose every bet. I am a patient with hemophobia, and you want me to give birth to a child?! System: "Ding! Congratulations to the host for giving birth to his first son, awakening the [Immortal Body], and being rewarded with [Eternal Youth]!" "Ding! Congratulations to the host for giving birth to his second son, awakening [Wood Release Blood Successor], and being rewarded with [massive increase in chakra]!" "Ding! Congratulations to the host for giving birth to twins, awakening the [Tsanseigan] and [Sharingan], and being rewarded with [Full Mastery of Yin-Yang Escape]!" … Some years later. Payne: "Let the world feel the pain! Shinra Tenzheng!" Behind Tsunade, a baby holding a milk bottle yawned and made a casual move: "Wood Release: Thousands of Hands!" Another girl with pigtails that towered over her eyes widened: "Don't disturb my mother's drinking! The sky is hindering Zhenxing!" The third one... Looking at the row of naughty children standing behind her, including the Rinnegan, Tsangshengan, Sharingan, Byakugan, Corpse Vein, Ice Release... All kinds of blinding children with various blood inheritance limits, Tsunade drunkenly pinched her waist and stepped on the board of Uchiha Madara's coffin. "Madara, don't you want to dance? Come on, I have a hundred or so children, you can choose any one to play with you!" The entire ninja world was numb.
