City of Sin (Yanyu Jiangnan) - Vol 9 Chapter 115

She is the rising (new) movie queen of the entertainment circle, who is also Beijing’s Ye Family long-lost Second Young Miss. Everyone knows that the Ye Family Eldest Young Miss is the chairman of Fenghai Group; Ye Family Third Young Master is a Major General of the military area; and yet, Ye family wants the second young miss to come back home, but she is just a flower vase (pretty face) of the entertainment industry.

After living a mundane life for over a decade, one night, Ji Minghuan suddenly awakened a unique ability to “create game characters in the Real World,” and each character came with its own main quest and a special skill tree system.Since then, he couldn't stop himself. He kept creating new characters in the Real World, developing skill trees, and cultivating character systems... all he needed to do was to enhance the character's reputation to strengthen their abilities. Thus, he started causing trouble in every way possible to attract attention, stirring chaos like a stick in the world of superheroes and supervillains.When he came to his senses, Ji Minghuan was sitting on the moon, gazing at the devastated blue planet, with a group of maxed-out game characters standing behind him. He couldn't help but innocently exclaim:“I really didn't intend to destroy the world at the beginning!”

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?

She was transmigrated into a novel where she became the cannon fodder who abused the male lead and ultimately suffered her demise under said male lead. And to return back home, she had to obtain the city boundary map first.

Ye Mu doesn’t want to play a game! Now that she’s inside the book with such a plot, the only way around her death is to kill the male lead first and let this world collapse!

However, upon seeing a scraggly, skinny little boy whose brows were full of perseverance, her hand won’t move…

Well then, she would subdue the male lead’s tyrannical tendencies! How to do it? Raise the male lead and have him help her find the city boundary map? That’s a good idea!

Despite raising him properly, the male lead seems to have grown into a devious man who won’t listen to her. Moreover, he lures her over with the city boundary map.

“Do you want this or not? Then come to my bed.”

Her face was full of tears. Where was the promised honest and upstanding monarch? Does she have to raise him all over again?

The man smiles and pats her on the head, “Come on, stop crying. Wash and go to bed.”
