I Am Uchiha With A Son System

When he was in Konoha, he didn't think to write any novels because he was busy developing the village, but right now he really needs money so his descendants can live comfortably. He expects that within 5 years, he will have at least 20 children.

A/N: I noticed I said novel; no, this one is a manga.

After showing the manga to his wife, he then began to continue drawing until there were enough and managed to draw more than 150 pages. By using Shadow Clone and a bit of fuinjutsu, he managed to properly draw the story.

The story began on that fateful day, when Nobu wanted to commit suicide but met this little girl. Looking at the weak child who wanted to live and eat many foods, even though she is a weak child, makes Nobu, as a grown person, feel embarrassed.

What touched him the most was that after that girl finished eating the buns, she smiled widely, became very happy, and thanked him.

"Sakura, do you want to follow me?"

"I don't want my mama said don't follow the strangers and don't take anything from them," Sakura then realised she just ate the bun from Nobu. "OMG, my mama said don't take food from strangers because I might be kidnapped."

Feeling amused, Nobu then laughed. "Hahahahaha!"

"Uncle, will you kidnap me? I'm thin and don't have much meat, if you wanted to eat me my meat are not delicious"

"You girl, I don't want to kidnap you. You said your mother just being killed by a bad guy. Will you become my daughter instead?"

Sakura then smiled widely she never had a father, since she was young she remembered her mother said his father left her but never come back. Neighbour said because died killed by bad guy, unfortunately they didn't find his corpse.

Then begin, Nobu become a single father. He then come to konoha to visit Madara and Hashirama and told them about his adoption to them. His live begin to change because of the addition of this little girl.

After finish writing for book 1, he then began to think how to produce as many as possible so he can sell it to others. He then forgot he is master in fuinjutsu and has a lot of chakra with ease he can use shadow clone to do his labor. 

He then began to create new fuinjutsu, he called it as printer fuinjutsu where he can use a function like modern printer which can copy, scan and print the paper.After a week he managed to produce 10,000 copies and wanted to sell it to others.

He then met his father-in-law, Uzukage.

"Father in law, I need your help," said Setsuna.

Uzukage was a bit shocked. What does this strong guy want to do? Setsuna then gave him a book and told him to read it first. At first, Uzukage looked serious, but by the end of the chapter, tears began to form.

"This sakura is so pitiful... Good job, Nobu, he then realised Setsuna was in his office. "Hmm, so what help do you need?"

"It is like this, this one is a manga drawn by me. I need your help to promote this book. I also plan to open a new shop in Uzushiogakure."

"What, didn't you want to become a ninja? Why suddenly want to become a merchant?"

"Because I don't want to leave Uzumaki Akari alone. Shinobi Live is dangerous even though the pay is high."

Uzukage then looked deep into Setsuna's eyes, and he agreed, "Ok, I will help you this time."
