a chat group is still basically a type of system and as you pointed out he learned from multiple worlds which is something the chat group made him capable of

sure you could but that's assuming they like to talk to people who are half distracted

he really doesn't have free time mate if you notice all his time is practically spent on his already existing training plans to add more would be reducing other types of training but his current training are mostly the foundations of being a Shinobi so that's really not a good idea maybe wait till he reaches a high enough standard in those then switch to your idea

you say it like such a barrier actually exists in the series... if it did then the sealing masters of the uzumaki family should have had it and not been able to be wiped out basically at all because that defense would make numbers rather meaningless and high levels could've been dealt with via the death god masks

in my opinion supernatural is just a subcategory of fantasy usually of a low power level too

as an adult having an undisturbed personal place for adult or private things when you need it seems like a reason for me but that probably depends on the person so your reason makes sense to some extent

yes and no do you really think border fortifications matter much for Shinobi? no, it's likely done by enough manpower even during wartimes so it really wouldn't make a difference what the terrain is in most cases tbh since any decent Shinobi should know wall walking it's difficult to trap them in valleys or anything like that pretty much only doing things like setting up explosive tag traps and such would count as a terrain advantage but while that takes time it could be done pretty much anywhere

that would be a valid reason but would also require him to have free time regularly

right it's just some basically useless knowledge I learned reading business books out of boredom in class a long time ago when I still went to school

really just a reminder that you've been injured it's not like I wouldn't know i have a few scars myself and while I've encountered life threatening things none of my scars were received in such incidents but in surgeries and motorcycle accidents (turning on loose gravel too fast isn't good especially when a pot hole appears) but all in all the scars look bad and remind me of unpleasant things so I don't feel what i said is wrong but you are entitled to your own opinion
