MTL - Hail the King - ~ 1150, mechanical monster army

Finding an ancient treasure was not as fortunate as one might expect. As soon as Bai Rouyun had left the grave, countless sects and hidden families set out to kill her for the sake of obtaining her treasure for themselves.

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?

- Description from Novelupdates

Painfully shy and conflict-averse, Yun Ruoyan is a scion to a noble house only in name, a puppet embroiled in political machinations beyond her ken. At the tender age of eighteen, poisoned and at death’s door, she finds herself thrown out into the streets. Her relatives have all been executed, betrayed by her dear husband and her cousin. With her dying breath, she curses her own weakness and swears revenge.

When Yun Ruoyan awakens once more, she is thirteen, transported five years into the past by the will of the heavens. Her death-defying experience has changed her: no longer is she the malleable creature she once was. But more questions await at every corner—what is the truth behind the birthmark that disfigures her appearance? What are the circumstances surrounding her mother’s mysterious death?

Will the phoenix rise from the ashes, or will she fall once more in thrall to fate?

I’m a high school student who became an author after debuting at Dengeki Bunko. After taking a year of hiatus from school to write my work, I transferred out to another high school to study, and met a girl called Eri Nitadori in school, a rookie voice actress cast as a character in the anime adaptation of my work.

In school, we treat our professions as a secret. However, Nitadori’s very popular in class, and I’m a loner…the only chance we get to talk to each other is when we take the Limited Express train together every Thursday, seated side by side as we head off for an anime, After Recording.

To improve her skills, she asked me questions regarding the profession. While I was answering the questions regarding the process–how did it end up like this.

This is what I last remembered before I lost consciousness, and the story of my near-death experience.
