It's good that the protagonist was originally pretty decent. It's annoying when a useless waste suddenly becomes a god

I would keep it until actually getting a better one.

Actually ancient people would probably prefer to leave it empty than sell it but sure, why not

I really doubt that. Unless there is some rule that requires a household registration to buy slaves and that's why the MC can't go for the cheap ones.

So his willpower has been strengthened by about a million or billion times since a few years ago.

I would argue that someone who has several academic qualifications, is published in several journals that people study and is generally recognised by the scientific community (while having a severe condition that impedes his daily life) may not necessarily be a genius but is definitely above average in intelligence, talented in his field and hardworking. At the very least. Now add the IQ of an average person to that and you have the minimum qualifications of this MC. I get that he may have some sort of inferiority complex about his hands on abilities but it's unreasonable for a former scholar to not even believe in his own brain.

I still don't see how he 'failed' during the kidnapping. He attacked and injured the assailant, attempted to escape and resisted almost to the very end while severely overpowered both in size and in strength. He only gave up a few moments before being killed after seeing no solution to his predicament. Yet the author keeps emphasising his failure, his fear and unworthiness. He is indeed an adult in mind but his saviour doesn't know that. He didn't even praise the kid. Honestly I don't know if I would have done better as an adult. It's not like he froze in fear (a very normal and even common child's reaction)

It's a bit abrupt but it's nice to have a protagonist that wasn't completely useless before the cheat.

You can get such a supernatural disguise skill by putting mud on your face but you can't punch and kick randomly every day to get martial arts ?

Compared to brainless harem, this version seems much better.

This novel is already looking promising. 👌👍

I have been playing for so many years that the only way to get a different looking character is by using the randomizer, and yes I also have cc :)

Yes, it's for the good of the sect I tell you.

Most MCs avoid military organisations because of the restrictions so it's interesting to read something different for once

And then there is the normal part of the world where everyone counts in 24 hours and not just the military.

In fact it's quite reassuring that this is his only ulterior motive

That's what you get for throwing away the almighty stick!

How is core formation after golden core? Whatever

It's an orphan child with limited world view. If she annoys you then wait until she magically teleports in the sect and gets the shock of her life. I'm sure you'll enjoy it. :)

It's a basic book so no matter how broken your learning buffs are your understanding will never be beyond basic. Definitely not enough to apply in reality and succeed first try. In any science related field you are meant to look up extra materials, books are never enough. When it comes to core technologies like these, not even science journals are enough, except if the system gives out a step by step IKEA manual plus parts.
