Silent Witch - Chapter Volume 1 1: Hongyarabubbo! (scream)

When a young woman is killed in a traffic accident on her way home from work at a tax bureau, she suddenly finds herself transported to the world of the otome game she was playing the night before – but instead of the heroine, she’s been reincarnated as the bad guy! Using her knowledge of the game, “Iris” manages to avert personal disaster and decides to rebuild her life with her modern-day economic know-how. This is one mean girl who isn’t going to let her perceived reputation stop her from being a heroine!

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?
