Maoyuu Maou Yuusha - Volume 5 Chapter 4, “Without the Hero, the Demon King’s hands are tied”

The later generations immensely revered Great Wei’s Jianan Emperor. During the period of his reign, Great Wei entered its golden era.

Interestingly, all the records, that glorified his accomplishments unanimously agreed, that Jianan Emperor had only one flaw in his life: He favored only imperial noble consort!

Zhou Tong was very annoyed. She time-traveled out of blue, didn’t even have time to take a breath, and yet, already had to deal with troubles.

What? The original owner of her body was a walk-on cannon fodder*? She couldn’t even be regarded as a second female lead?

Zhou Tong is angry! Change, it must change! This plot needs a beautiful turn around in order to be worthy of sis’s coquettish personality!

This is a story of the unfortunate time-traveling lass, who possessed the body of reborn aboriginal maiden and became the Great Wei’s beloved imperial consort.
