Its been a while, why she has this berserk stat again? and that voice?

The blueprint probably can be found in one of those ancient text. So they just need to do a lot of trial and error to reproduce it

Its way earlier than that. Abbas Ibn Firnas (810-887 AD) was the first documented person to attempt human flight with a flying machine. A feat that earned him the title of "father of aviation".

But unfortunately, western historian tend to wash off non western achievement and attribute it to westerner instead, hence why he isnt well known. Just like the 'father of scientific method'. And a lot of non western name were westernized, or just removed.

We do learnt something, we are exposed the danger of the demon for the first time. And this world without the fantasy magic and primitive weapons has to face such monster.

Well at the very least mc didnt defeat it, that would be too thick of plot armor. While mc has proven to be quite a fighter with the bear, with his still under developed body, no way he can defeat a monster with regen that soloed a group of adult soldier.

Finally, a fantasy element

by kids you mean modern world. For vast majority of human civilization beside modern time, even the concept of teenager does not exist. They generally mature early, or should i say normally compare to modern time where children mature really slow.

I was hopeful when the map say dragon, implying this world might be a fantasy world, but nope, the dragon most likely just a metaphor for being danger of unexplored area, implying this just a normal different world during medieval age.

Their civilization already has the technology. That's why its in the book. We are talking about mc's village specifically. They dont have livestock. Their only source of meat is from one person hunting. So far there is no indication of famine in the village. The one that died are from injury or illness, so there was never a need more producing more food. Naturally they dont know about the technology since there was no need for it.

mc is gay?

Not just a knight class, he also the only knight class there

Yeah logically, but public perception not something by logic. Just how media can brainwash people to convince them that bombing children is good

In original story, it could be that his parents killed by the wolf. The whole event was riddle with death flags. His father would originally succumb to his injury, and his mother probably would died to the little boars.
Being emotional, he blamed the baron. And without loving parents and that sentiment, he start growing up more twisted

...which part of her is spoiled?? She literally working as his father representative. You think spoiled little girl would travel around riding horse to multiple villages that would definitely not be a luxury. Not to mentioned she s a training junky, and studious. A bit 'selfish;' yes. But I would hardly call that selfish.

If the village have the human resource, they should let mc's family become the instructor for the village, and they handle the other stuff like farming. Only 2 peoples seem lacking as protecting force

Fortunately there is no tragedy tag, because they set up so many flag for his parents death, Loving family, original turn evil, mentioning 'worse to happen'.

And it kinda sad that mc didnt think much of his mother of previous world. She definitely work really hard as single mother to support mc

I hope Leon remain friendly after this. I kinda bored of Protagonist turn out to be ass plot

What the point of return to the past if they still dont have the solution for demon king revival?

Honestly I was hoping that he dont kill Reynold. While he is annoying, he did nothing deserve to be kill. He is confusing Echidna with different evil dragon, and Valzahark just plain evil before he met mc

wdym now? He has no obligation to be with mc, so i dont know why you find that offensive. Not to mention cm himself never actively approach the protagonist.

The protagonist also right now is a nerfed version of him due to lack of player that has the knowledge and skill behind him, so cut him some slack
