He’s still weak after the fight mentaly and physically. And overall didn’t take the advantage of his future info, his system, and his formation to the fullest. He just spent most of his time getting a comfortable life with his family, that shows ignorance cuz who would think that being in the fire country would mean they are safe from those outside? Or rather inside the fire country? At least they finally got some drive to improve and got a grudge against konoha. The Mc made a huge mistake in believing he can escape the ‘darkness’ that is in shinobi and konoha,
Do you know what is screening? Every Ninja Village, large or not, will surely check every single person entering their village in order to differentiate between civilian, merchant or spy. With the MC's lack of any sort of credible identification, he will definitely be red listed.
Byluffy02:I made this suggestion before the first child grew up, and when I did, I said that if his children stop growing between the ages of 8 and 10, he can join the academy and educate his own children if he reaches a certain level. Also, if you look at different sources, Konoha is a very big place, it looks small in the anime, but the number of passengers entering daily is too large and the country of fire is very large, so the children coming from it do not attract attention unless the main character gives birth to 100 children per month.
If the main character calms down and thinks, he realizes that it was the vintner who betrayed them. Since he can't take revenge on her in the village, he may pretend to have been taken prisoner and say that they have a large amount of wine on their hands and that the Konoha genin is waiting for her outside the village. In this way, the merchant comes out with a large amount of money. In addition, they prevent both revenge and possible danger. Since the Konoha rank is low, the genin level of up to 2 or 3 people will send the ninja to seek the lost ninja. The only person who can betray them is the trader and once you eliminate him, the low level ninjas can't reach them they can also access low-level chakra books when they receive a large amount of money from the merchant. but it is impossible to talk for the middle and high level, after all, even the emperor of the fire country cannot reach it, he only invests financially in hidden villages to protect himself
