Ding Shan had been a hot topic for seventeen years —from the time she debuted at the age of three with her pure and cute look, all the way until she was twenty years old. She even took home three golden actress awards at her coming-of-age ceremony when she was eighteen years old. Her life seemed so beautiful and filled with applause. However, behind that beautiful scene was a grave filled with lice. Since she was three years old, her family had treated her as their cash cow.

Her parents’ wickedness caused her reputation to rapidly plummet when she was eighteen years old. What was more terrifying was that they even imprisoned her. They drugged her, beat her, used her younger sister as a threat against her, and turned her into a plaything for wealthy businessmen. Ding Shan endured the humiliation for her sister’s sake, then finally sent those beasts to prison two years later. Just as she thought she could finally clean up and live a good life with her sister, reality slapped her in the face. “Why?” Ding Shan asked her sister from where she was tied to a familiar iron bed.“No reason, really.

I just hate you, so I drugged you two years ago. I’m the one who pushed you into hell. I’m also the one who posted that viral video which exposed you back then,” Ding Yuan said as she happily inspected her red nails.“Oh, by the way, you’re not my real sister either. My parents kidnapped you from some ravine.

Your parents chased after you, but my father pushed them off a cliff and they died. I can’t really remember since it happened so long ago. Plus, I only heard about it occasionally, so I can’t remember the details anymore.“Also, you’re tied up here today because your boyfriend, Wen Xiu, sold you for 10 million. You’re still worth a lot of money, so you should perform well tonight. Ding Yuan reached out to pat Ding Shan’s face, then injected her with an aphrodisiac.

The fiery burn that coursed through her body made Ding Shan weak, but the hatred in her heart kept her mind clear and awake. Drugged and left unsupervised, she ended her life with a knife she found in the room. As her life came to an end, Ding Shan swore that if she could start over, she would make all those who had wronged her pay all that they owed her. When she opened her eyes, she had gone back in time to two years ago! So, let’s see how she’ll turn the tide in this life!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

Easily cowed and bullied, she was the useless, ugly woman with no talent in medical skills. Supported by millions, he was Tianning’s most respected duke with the power to move all under Heaven. On their wedding day the bridal sedan was carried to the front doors, but the Duke of Qin’s gates were shut tight.

They told her, ‘Come back tomorrow.’

All alone, she walked step-by-step full of pride through the duke’s doors. Little could they imagine, this unattractive good-for-nothing was a beautiful, genius doctor of poisons!

—

After transmigrating to the past, poisons expert Han Yunxi finds herself on the verge of being married off to the country’s second most powerful man, the Duke of Qin. Her future life seems set–except her husband is an unfeeling ice block, her in-laws think she’s a eyesore, the empress dowager wants to use her for her own goals, and poison-related plots abound.

Alone, the intelligent (and sensible) Yunxi must carve her own space from the intricate web of court intrigue and the jianghu, relying on her words, wits, and wisdom to survive. Adapt when necessary, use force when required; to survive and thrive is the name of the game to a prosperous life.

No matter what, she’ll prove her right to live!
