Xiao Yijing returned to the real world from a narrow escape from the infinite world, and got the reward from the system – a group of unfinished buildings!

Although the unfinished building is in dilapidated condition and a lot of waste is waiting to be done, Xiao Yijing resolutely chooses to put it in ruins. Whoever likes to get a job will get a job, anyway, I won’t get a job!

When I have time to grow vegetables, raise chickens, herd cattle, and feed pigs, my small life is very nourishing.

Eh? Let me expand the scale of farming? ——No, it’s too troublesome!

What? Want to live here? ——Yes, you can settle the house by yourself.

ha? Do you want to help with work? ——Okay, you can handle it yourself!

Arthur got randomly transported to another world. Some people would find that terrifying, but not for him, who was tired of his old life; it was an opportunity.

And, after having bad luck all his life, the tide changed.

It was a world of magic where wizards fought side-by-side with their familiars. Arthur got summoned to be one of these so-called familiars.

He was furious. The thought of becoming a pet was not something he liked. Well, that changed when he saw who his master was.

A hot-woman. And, to make everything better, Arthur was inside the Frostpeak Magic Academy, which only had women students.

“This is heaven. All familiars are beasts, but I'm different. I'm a good-looking man inside a place filled with hot girls.”

When he thought his luck could not get better, he unlocked a system that helped him with everything. Of course, he used the system for a greater good, like getting girls.
