Rebirth in the 90s: Her Counterattack and Redemption - Chapter 975 - 574:

Is reality difficult? Is work unbearable? Is your daily Nine-Five routine boring? Is there no excitement in your dull life? Is the inner child in you dead? Fear not, enter Virtual Reality, and live up to your dreams.You can be anything here! Do you hear me? Anything! A King with an infinite harem, a cultivator that can slash the heavens with a sword, a child adored by a loving family, the protagonist of a story you create, and many more.You are limited only by your imagination.

We have all heard the legends of great wizards, but do we know how those stories begin? Ardan Egobar, a young man living in a remote corner of the New Monarchy Empire, does not. He doesn't realize that this story is about him. Not yet...In a world where steam locomotives chug along iron rails, where massive airships hover in the skies, where in the cities you might encounter orcs in suits involved in organized crimes, dwarves with cigars controlling major banks, or elves strutting down fashionable boulevards, where humans have built vast nations on the brink of a world war, almost anything seems possible.Maybe, in such a world, even an ordinary young man, the last of the mountain hunters, might one day become the greatest wizard in history.

Lin Ziyin, modern day mechanical professor especially hired by the school, had the potential for great achievement in her field. However, due to family reasons, she could only treat her mechanical research and teaching as a secondary job, pouring all her energy into the farm and the food business before. Despite her low-key approach, she was unable to suppress her sister's rage, and a furious car crash sent her straight to ancient times.Indeed, she had excellent character, so why did the heavens send her to the sparsely populated Northern Land. Known as the death zone, those who were banished to this borderland would spend their lives and perish there. However, Lin Ziyin was quite satisfied with her own identity. Even if she had lost the protection of her parents, she still had the protection of her siblings and grandfather. Of course, she also had her younger brother and nephew at home who needed her protection. This abundance of familial love was enough to compensate for the hardships caused by poverty at home.Poverty, she wasn't afraid of, as she had experience in farming. With large swathes of uncultivated land, the Northern Land was practically custom-made for her. The heavy workload didn't matter either, she was proficient in designing all kinds of small tools. Whether it was the emperor's absurdity, not providing aid to the border king, or the shameless Tatars that would rob them frequently, none of these posed a problem for her. She could think of solutions for everything. It wasn't uncommon for the border king to tell everyone how lucky he was to have married such a wonderful queen!
