Douluo Dalu 2: The True God King - Chapter 10: [DD2]:

When our protagonist becomes the game character Jun Karentia, she thinks she has it made. She may be just a lowly support mage, but with her knowledge of the game, she knows she can finagle her way to the good ending following around the main character, Fabian. The problem? This game doesn’t end after one playthrough. Jun is prepared to guide Fabian through the second playthrough to the true ending when… Fabian abandons her. Now the Grand Duke Mayer Knox—captain of the Dark Knights and the secret final boss—is determined to have her join his party. Can Jun turn the final boss into the main character? Why is Mayer Knox so intent on having her in his party? And when will these rumors about being his lover stop?!

First, this isn’t a story about how to seek survival during Doomsday! It’s rather about how to bring about the end of of times, to bring down the curtain on the world. It’s about how to set off a Zombie frenzy, how to lead the Devil into invasion, and how to guide the descent of Zerg! In this game of doom, I’m the source of everything!

Second, I need to thank those brethren who accompanied me until now. My thanks go to the Lich Monarch, Arthas Menethil (game: World of Warcraft), bringer of endless winter and death; to Alex Mercer (game: Prototype), who created life by consuming viruses; to the Worst Spirit Tokisaki Kurumi (Light Novel: Date a Live), controller of time; to the Magus Ascendant Xerath (Game: League of Legends), imprisoned by runes.

Ladies and Gentlemen, lets bring about a carnival of doom!

Follow Mira as she's thrust into a Cultivation World where the impossible is possible and reality can be whatever you want it to be as long as you're strong enough.

Disclaimer: I don't plan on adding romance early in the novel. I will probably add some later in the novel, but it won't be the main focus. If there is any romance then it will be yuri.

This novel will also primarily focus on females. Of course, there will be males in the story, but for the most part, they won't be important characters.

A bittersweet drama: As long as the heroine forgives her kindly and kindly, pays without regrets, and gives up again and again until the bad guys who bully her are old and unable to act, she will get a happy ending.

When Mercury is dressed as the heroine of each bitterness drama…forbearance? Pooh.

Terrible heroine, change her life online.
