MTL - Niu Fei Zai Xia - Chapter 1221 Cave kill

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

I was stuck in a dungeon explosion while working so hard that I actually died.

But when I opened my eyes, I was back to the time of 3 years ago!

Well, I will live differently in this life. Salary is goodbye to s*ave life. I quit immediately and set up a cafe in the store my grandmother left behind.

There are no customers because she is right in front of a dungeon, but it doesn’t matter. All I want is to work two days and play five days. But.

Also, the attractive regular customer who keeps bothering me is somehow unusual.

It doesn’t feel good. Isn’t it like the story of the main character of the RPG, who was just trying to run an errand, and ends up fighting the devil after getting caught up in something annoying?

Yes, I will not. I can not. I have no intention of playing more than the role of a novice innkeeper.”

Jun Ye travels through worlds for unexplained reasons and is always cast in subservient roles. Unfortunately, that wasn’t his style. Let the counterattack commence!

The harem would not be too large(I'm not sure how many but probably just 4-5 main and few other here and there). All the girls would be getting their time and story.2. The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff. It is actually quite a wholesome story focusing mainly on adventure, action and bit of romance and slice of life.
