I Transmigrated to Ancient Times and Became the Prince's Most Cherished Consort

[Alternate history + sign-in System + sweet romance + both chaste + no saintly heroine]

Ling Xue accidentally lands in the State of Yunli amid the chaos of war.

She is discovered by the male lead, Mo Beiyuan, and receives a sign-in System.

Ling Xue knows she's transmigrated into a novel she hasn't had a chance to read yet, and she plans to stay away from the male lead.

But the System tells her that leaving his side will bring her a constant string of bad luck and ultimately lead to her death.

To stay alive, the heroine sets out to uncover the secret and strikes a deal with the male lead.

But she never expected...

System: [Congratulations, Host! You've completed a hidden mission. Reward upgraded!]

Ling Xue: “Mo Beiyuan, get off me! You're not allowed in bed for a month!”

Mo Beiyuan gazes at the several chests of gold and jewelry before him, looking troubled.

“I just don't know if this little bit of money will be enough to make Xue'er happy.”

[Alternate-history setting; no need to overthink the details.]
