After Planting a Love Bug in My Brother-in-Law

Xiang Yao's mother was a medicine slave. To save the life of the First Madam, the old marquis drained all the blood from her mother's body, and her mother died in agony and despair.

Though Xiang Yao was also the old marquis's daughter, after her mother's death she was beaten and bullied every day by the First Madam and her legitimate older sister. Xiang Yao endured it all, waiting for a chance to avenge her mother.

When she was fifteen, Prince Ning went to the southwest to take up his fiefdom and asked the emperor for her older sister's hand in marriage. The marquis's household enjoyed a brief moment of glory.

Prince Ning was the emperor's youngest son, a sinister man with countless deaths on his hands. For some unknown ailment, he had been seeking doctors and medicine ever since arriving in the southwest.

Her older sister and the First Madam plotted to send Xiang Yao to Prince Ning as a medicinal ingredient and drain her blood.

Xiang Yao knew she couldn't wait any longer. She approached Prince Ning and used the secret art her mother had left behind to plant a love Gu in him:

"From now on, I am your master. You can only obey me."

When her older sister came to confront her, Xiang Yao fell into Prince Ning's arms, her eyes brimming with tears.

"I truly love my brother-in-law."

Prince Ning held her tight and nodded along. Xiang Yao smiled triumphantly.

From then on, she controlled him, making him protect her, dote on her, and avenge her.

If there was one downside, it was that the love Gu worked well, but Prince Ning was exhausting in bed.

Xiang Yao knew that was the price of using the Gu.

She wiped out her enemies' entire family. All she had to do was kill Prince Ning, and she could escape to the hinterlands of southern Xinjiang.

On the day she fled, Xiang Yao looked at Prince Ning. He was very handsome, and he was good in bed.

That was the only time Xiang Yao's heart wavered.

After that, though, she never found another slave as good as Prince Ning.

One day, she was about to plant a Gu in a young man when she turned around and found Prince Ning standing behind her, furious and glowering.

Xiang Yao closed her eyes. She knew the love Gu had turned against her. She had made him her slave and killed the woman he loved, along with his father-in-law's whole family. He must hate her to the bone.

"Please don't kill me, all right? I'll obey you. I'll do anything you want!"

Prince Ning glanced at the young gentleman, knowing that men who looked refined were the best at seducing women.

Looking at Xiang Yao in his arms, he suddenly felt playful and put a pill in her mouth.

"From now on, you'll obey me. I'll be the only one in your heart."

Xiang Yao silently wept against his shoulder. How had he learned to use a Gu?

"I understand, Master. Please be sure to give me the antidote every month. Don't use a Gu to torment me!"

Prince Ning sighed helplessly. "...Call me husband."

There is no such thing as a love Gu in this world. It's simply that one is willing to be enchanted by the person one loves.
