All Hail Cousin Brother Novel

Yu Youyao, plagued by a terrifying nightmare of her impending doom, envisions a future where she is married to Marquis Song Mingzhao and used as a "medicine-human" for her third sister, Yu Jianjia. After three years of life-draining blood extraction, her life ends in a gruesome death. Upon waking, a frantic Yu Youyao decides to avert this fate by latching onto the first man she sees: her maternal cousin, Zhou Linghuai, visiting from the You Kingdom. Promising him a lifetime of devotion, she seeks his protection. Zhou Linghuai, captivated by her plea, agrees to become her guardian, aiding her in seeking revenge, thwarting schemes, rejecting unwanted suitors, and ultimately achieving greatness. As Yu Youyao matures, her dream begins to materialize with Song Mingzhao's marriage proposal. However, Zhou Linghuai intervenes, claiming her as his own and forbidding her from marrying anyone else.
