[No System + No Heroine + Not Brain-dead + Mostly Everyday Life]
Akimichi Tangdong became the biggest loser in his clan. Unable to master secret techniques, he scraped by in the Third Shinobi World War, lucky just to stay alive. After the war, he opened a ramshackle general store and collected a pile of unwanted “junk.”
He put a broken kunai up for a million.
He refused to sell a battered box of Shuriken engraved with a fan.
Everyone laughed at him, calling him a crazy old has-been who'd survived on luck alone.
Then the Otsutsuki arrived, and Konoha fell.
The old soldier everyone had mocked slowly tore off the talisman he had always worn, and straightened up.
The enemy trembled. The whole village was stunned.
Just then, a green figure came racing over in a wheelchair, tears streaming down his face.
“Tangdong! My dear friend! Your youth has never faded!”
Only then did his apprentice, Uzumaki Shuoye, realize that what he polished every day in the shop wasn't merchandise, but... one buried heroic saga after another.
Five stars are only used to support new authors. The following is a brief review: After reading twenty chapters, there is no protagonist, and they are all played in supporting roles. The timeline is before and after the genin in Boruto, but before the chunin exam. If it weren't for AI, then I think it's very stupid, and the writing is still a Boruto biography. The follow-up will either time travel or recall. Looking back, I still have to start from the Hayate World War II. Otherwise, there is no water. From my observation, I may not be able to survive until that time. My humble opinion is for reference only.
