To Bewitch a Devil - Chapter 10

Qin Yi was reborn half a month’s time before the apocalypse. In this life, having already seen the true colors of her scumbag sister and father, she swore to let them have a taste of their own medicine—an eye for an eye. She disguised herself as a man and kept improving, getting stronger day by day. Common people hailed her as «Prince», making countless people bow in homage.

Throughout the Ming Kingdom, Jun Hua was famous for being a useless girl without any talent worthy of praise. Everyone mocked her, belittling her for latching onto her brilliant brother Jun Min, the young and peerless general admired as the most talented prodigy for his talent and his ability to change the fate of the declining Jun Family.

Never in their wildest dreams would they have suspected that Jun Hua is the young general who is leading the army on the frontline, Jun Min!

“She has no talent as a girl, but has the brilliance of a great general!”

Her journey towards revenge is something she has to do on her own. And yet, on that path she will gain allies, friends, and possibly even...... a romance?

This is Jun Hua's story, a story that shall be carved into history as the legend of “the flower who blooms from the battlefields”.

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?
