Naruto Debt Collector: Let Tsunade Repay My Kindness at the Beginning

Ye Feng is a time traveler, a man destined to become the savior of the ninja world. From the moment he traveled to the ninja world, the people of the ninja world already owed him a debt of gratitude. Now, the 'favor system' allows him to recover his debt in advance. 'Miss Tsunade, the debt you owe me is 1.9 Billion in cash. How do you want to repay it? ' 'No cash? That's okay. There are many ways to pay off debts. I'll give you three options. Choose one.' Looking at the three contracts covered with magnificent purple runes in front of her, Tsunade despaired. There is no other choice but to sign and post. In an instant, the Yin Seal diamond-shaped curse pattern between Tsunade's eyebrows burst into purple light, and Tsunade felt that she was done playing. 'Xiao Nan, the debt you owe me is 1.9 Billion in cash. How do you plan to repay it? ' 'I have cash, I'll pay it back now' 'Huh? Don't! Xiaonan, Sister Xiaonan! I beg you, don't pay me back in cash, can you find other ways to repay the debt? Onegai! ' 'Uchiha Obito? What? You don't owe me any debt of gratitude! This just shows that you are a hopeless person, so you should die.' On the road of debt collection, Ye Feng will not sit back and rest in vain. He continues to accumulate virtues, accumulate kindness, and establish deep emotions with each debtor. Perhaps, the ninja world can really become a little more relaxed and sunny.
