Yu Youyao had a nightmare. In her dream, she was married to the Marquis’ son, Song Mingzhao, and had become a mere medicine-human for her third sister, Yu Jianjia. After having blood extracted from her heart for three years, Yu Youyao’s life was nearing its end, so her wrist was slit and she died just like that.
Upon waking up, her heart thumped wildly and she decided to choose the first man she saw to escape that tragic fate. Thus, she clung onto the leg of her maternal cousin who had come all the way from the You Kingdom. “Cousin, I’ll be good to you for the rest of my life.” 
Zhou Linghuai looked at the girl nestled in his arms. She had a lovely face and puppy eyes. Despite his usual ruthlessness, he suddenly found himself unable to reject her. And so, he became Yu Youyao’s protector, helping her to take revenge on those who bullied her, fend off the schemes of others, and reject all of her suitors. He even helped her attain glory and magnificence. 
Once Yu Youyao reached adulthood, events started to progress according to her dream. The Marquis’s son, Song Mingzhao, had indeed come to request for her hand in marriage. However, Zhou Linghuai pressed Yu Youyao against the wall and said in a low voice, “You’re mine. You can’t marry anyone else!”

All Hail Cousin Brother

Yu Youyao was stunned for a moment before her eyes widened. "It won't take 49 days like in the book, right? Then Cousin…"

However, Zhou Linghuai laughed when he heard that. "Don't think too much. It's just a medicinal pill to nourish the body, not an immortal pill. Why would it take so long? The medicinal pill will be refined in three days at most."

When Yu Youyao heard this, she was relieved. "It's not as it seems. Otherwise, Cousin would have to wait for a long time, and his recovery would take a long time."

Zhou Linghuai looked at her. "Don't read any more nonsensical books. If you like books, I'll give you a few some other day. You can choose one."
