In her previous life, Yao Yao, a young cat-tribe girl, followed her mother to seek refuge with the wolf clan's royal court, only to become a living blood supply. She was cruelly drained of blood and died. Reborn on the day her parents dissolve their mate bond, she discovers that her older sister, Qi Qi, has also been reborn. Qi Qi snatches the chance to go to the royal court, while Yao Yao chooses to stay behind and marries off her beautiful, delicate father, Qing Xiao, to Chi Lan, the tiger-tribe female chief who has secretly loved him. After awakening wood-element abilities and a spiritual spring space, Yao Yao grows crops and builds defenses, establishing a new home under the loving protection of her four tiger-tribe elder brothers. However, the wolf clan covets Qing Xiao's pure bloodline and launches repeated assassinations and beast stampedes. Yao Yao and her family fight back together, then investigate blood-trading contracts in Zhongzhou and rescue beastfolk being used as sacrifices. From a living blood supply at the mercy of others, she grows into a powerful protector of her family.
