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.

Lin Xiao was addicted to reading Qidian novels. He always fantasized that he would have a day when he could transmigrate and then embrace beautiful women all over the whole world, becoming the strongest person in the mainland.

After he really transmigrated, Lin Xiao stubbornly always believed that he was a protagonist until he met Ling Luo.

Only after being killed by Ling Luo did he know that he was only a cannon fodder villain in a novel.

When he restarted his life and hatefully wanted to oppose his fate at least once, he was ruthlessly crushed again.

Okay then… since a protagonist was determined to be like this, he wouldn’t oppose a protagonist anymore…

The two of them were similarly straight guys…

When he restarted his life again, Ling Luo unexpectedly suffered an Love Herb’s poison…

Lin Xiao internally cried as he looked at a certain person who tied him onto an obelisk in the back and thought, who could tell him what this was all about?
