Extraplanar Lord

If you find any typos, please post them here and I will correct them - thank you for watching.

I feel very retarded. Are all NPCs idiots?

You are clearly a time traveler, but you don't know how to develop technology?

Doesn't the protagonist upgrade himself? He just keeps developing his power. How can he stop someone else from assassinating him later?

It feels the same as urban pretentious writing

It seems that there is no golden finger, and I haven't seen it. Moreover, the lord at the beginning is the protagonist of the trade route. It seems that he has no extraordinary power. How can he get it? The nobles next to the trade route territory don't bother you.

I only saw the protagonist showing kindness, but not the protagonist showing power! Management is a science

There is no one around, a group of old and weak people can get there in three days

As a dog? Or take a wife? Is it simply repaying a favor? .
