MTL - Feng Jue of Ancient and Modern - Chapter 62 takeaway goddess

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!

By the time Xiao Yijing came back to her senses, the people who worked at their own expense had already gone to the sky, and the unfinished building was unknowingly revived!

(There is a male protagonist, but there are very few emotional scenes)

PS. Cover not mine, I just found it on google.

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

A data loving young man from Earth has an accident which transports him to a dark land filled with terrifying creatures and magical powers. Fortunately for him, he has a Biological Assistance Chip to ease his path. However, things in this bizarre and strange world are not always as they seem, and, though it is a tremendous asset, the chip doesn’t always work as expected. With all of the crazy creatures and magical mayhem around him, one can only wonder what the future holds for this young man…
