Which Recommendation For A Book Has A Similar World-Building To 'Sword Art Online'?

When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

Evy was a simple-minded girl. If there's work she's there. Evy is a known workaholic. She works day and night, dedicating each of her waking hours to her jobs and making sure that she reaches the deadline.

Evy will do her best to live the life she wanted and surprise a couple of people on the way. Unbeknownst to her, all her actions will make a ripple. Whether they be for the better or worse.... Evy has no clue.

One moment he had just read the strangest book he had ever come across, the next he was stumbling into the world of that same book. Now Mars is trapped in a fantasy world as a nobody, and the gorgeous, cruel Crown Prince who just kidnapped him thinks he's a spy. Keith Elarion's solution? Keep Mars under his personal, infuriatingly attractive supervision. Mars’s plan is simple- survive, avoid the plot, and find a way home. But the prince is nothing like the two-dimensional villain from the book. Keith is all intense green eyes and confusing, rough kindness, and he’s decided Mars is his to keep. When Mars accidentally unleashes a power he should not possess, he becomes the key to a conspiracy that runs deeper than the novel ever revealed. His meddling changes everything, accelerating a plot that was supposed to take years. To top it off, a cryptic bird-god just told Mars he's not just a lost college student. He's the son of the goddess who made this world. To save Keith, stop a divine war, and maybe finally kiss the man he falls hopelessly in love with, Mars has to do the one thing the book never planned for: he has to rewrite fate itself.
