One morning, Gu Tiantian wakes up to find her innocence gone—and her temper flaring.Every time she glares at him, cheeks flushed with outrage, Bai Chenyao cocks an eyebrow.“You don’t want this?” he asks, voice cool.“I never did!” she snaps.His only rule: her consent is optional; his desire is not.Cue Gu Tiantian’s inner scream: Then why even ask, you iceberg?!PS:A genius CEO with zero EQ VS. a lovable, scatter-brained clerk.He thinks courtship is a hostile takeover; she thinks love shouldn’t come with fine print.Sparks fly, clothes vanish, and the “free pie” she never ordered keeps biting back—hilariously, endlessly, deliciously.

Perhaps it is the choice of fate. As a senior otaku, Qian Lingfeng got the “steel shell system”. However, when he swept the world with the system, became a local rich man, made all kinds of beautiful women, opened a harem, and realized the ultimate fantasy of thousands of otaku, he found that things seemed far from simple!
When the end comes, biochemical zombies suddenly come down, fierce beasts are in power, bloodthirsty zerg roam to kill the world, and human lives are comparable to dirt. Where will weak human beings go in this world? Is humanity going to be extinct? Or … can an otaku save the fate of the human race?
