Second title: “Everyone Gets Scared When the Consort Gets Fierce”

Qin Jiu transmigrated into a switched-at-birth novel.

She became the first daughter of a marquis’ household. She was swapped out maliciously at a young age and raised in the countryside.

The fake young mistress female lead was a rebirthed girl. The pearl of the capital, and the future wife of the second prince.

In the original novel, Qin Jiu had been jealous of the female lead and kept going against her, trying in vain to frame her. Unaware of her lacking capabilities, she even tried to steal the male lead from her. Eventually, everyone turned their backs against Qin Jiu and she was killed by an arrow to the heart.

After reviewing the plot, Qin Jiu tore up the script–She doesn’t want to be this villainess cannon fodder! Then in the next moment, she jumped into the arms of Regent Gu Zezhi.

Qin Jiu, “Sob sob sob…golden thighs!”

Gu Zezhi, “I’ll let you hug them.” The regent of the dynasty had a fierce reputation of great power and heartless killings. Many people hated him, feared him, and wanted him dead. Then, one day, someone saw the infamously fierce regent holding a little girl in his arms with a pampering expression. Gu Zezhi kissed her hair and spoke in a gentle voice. “You can get rid of anyone you want. I’m here.”

Noah was a nobleman. An orphan.Born with an empty constitution, he was pretty much useless…Until he realises the World’s Greatest Secret.The verse they were living in—It was a freakin fantasy novel.And the worst part?He was supposed to be the villain.***“Hehehe— So what? I just have to substitute someone in my place…Yes!”“All I have to do is to hire a Villain.”

“Martial Arts World...” Death murmured, shocked by the turn of the events. How could he, primordial being of the afterlife, get tricked by a mere human? Not just a mere human, but also earthling, race that was weakest of the twenty realms. Death realized the extent of his mistake. An earthling had just jumped into the river of the reincarnation, where he definitely didn’t belong. It was too late. The damage has been done. The matter was now out of his hands. “Kiernan Hunter...” ... Remake of the Martial Arts System, and while the concept stays the same, the story is completely different. A few names, etc, stays the same, but mostly whole new story.
