Shan Bei inexplicably transmigrated onto a tsundere cat named “Queen”, and was forced to appreciate the daily life of its owner, Mu Qing, and found that Mu Qing was not only coquettish, but also had an extraordinary obsession with her! Σ( ° △ °|||)︴

Fragment one:
Shan Bei’s cat eyes, which were originally staring at the computer, slowly turned to Mu Qing, who was staring at the document. His bi-color eyes were blazing with anger. This guy was yelling at her, and a hidden sex scene was deleted, deleted, deleted, and deleted a hundred times. What on earth was he thinking? ? !
Mu Qing couldn’t help breaking out in a cold sweat being stared at by the “queen”, how come the “queen” has become more and more real recently, she seems to feel that it is staring at her, hell!

Fragment two:
Shan Bei was sitting on the sink, when she saw Mu Qing who took off his clothes and walked into the shower, the cat’s eyes almost fell out, why does this guy like herself? ! Her figure is so good, although she is not as good as Shan Bei. Shan Bei was inexplicably happy, raised his hand to pat his chest, and touched a ball of hair.
Fuck-_-||, I forgot that I am a cat, with a single black line.
When Mu Qing turned back to get the towel, he saw the “Queen” was touching her chest with her head down? ! hell!

A place where the exiled are sent to die.Motivated by revenge, Magnus sets out on a quest to bring his own justice to his enemies. For that purpose, he is willing to go further than most others.But then he learns that if he truly wishes to change things, he can only find his answers beyond the gate.Having lived most of her life as an exile, Astra is a woman of few interests aside from survival and climbing the ranks of her clan.To achieve those goals, she certainly won't be squeamish when a chance literally falls into her lap, or will she?———————————————————————————————I am trying to go with a survival/“no modern tech” setting in this one. People from a technologically advanced society are thrown into a world where they can't maintain their tech. They are forced to rely on what the world provides where they have to make do with the limited resources they have and what little of their old technology is still working.

Not sure yet whether sufficiently advanced technology will be discovered later on to count as magic.It turns more political between the various clans later on.
