First of all this novel isn't about a particular genre, it has a bit of everything. This is a FUN novel.Imagine someone getting advance weapons like GUNS, GRENADES, BIOLOGICAL WEAPONS, POISON and he can shuttle back into the past. In the era where there were lots of kingdoms, brave warriors with strong physical attributes, fights with swords, bows and arrows. Imagine a weak human like him getting wild there with guns and grenades, killing strong and powerful people left and right. That's our MC.... more>>

Our MC in this novel gets an ability to shuttle between earth and another primitive barbaric world (kind of) where he tries hard to survive and somehow becomes Empress's Gigolo.

Now imagine someone from the past, when there was no such thing as science, shuttling into the future world full of scientific wonders. And imagine that someone to be a female and on top of that an Empress. What do you think she will do? Yes, our empress wants every wonderful thing for herself and her citizens. Our empress wants to eat tasty food, our empress wants to watch romantic dramas and movies, our empress wants advance weapons, our empress wants to listen music etc.

So this is second most important character in the novel, Empress. She is cold, ruthless and controlling. She wants MC to change her barbaric kingdom into something like modern earth, and as MC is a bootlicker (MC loves her so much), he is more than willing to do it.

Our MC is also decisive and ruthless, he thinks logically and takes good decisions.

Well, this novel has influence building. MC builts his influence on both earth and other world. Side characters are interesting and funny. Interactions between MC and Empress are enjoyable. The whole process of MC opening a school and teaching science and maths to strong barbaric martial artists cracked me up.

Overall, this novel has slice of life vibe with good amount comedy.

I have only read 600 chapters so I don't know quality of novel after that. <<less
