I Raise a Girl with Animal Ears in a Fantasy World

This is a fantasy world where "human race" and "animal spirit race" coexist. The Beast Spirit Clan is marked by features such as animal ears and tails. They are naturally innately compatible with the spiritual energy of heaven and earth, and their cultivation speed is much faster than that of human beings. However, thousands of years ago, the human race developed the "Spiritual Contract Technique" - by concluding a contract, part of the training results of the Beast Spirit Race can be transferred to themselves. Since then, the Beast Spirit tribe has become an object of enslavement, and high-level monks regard having a beast-eared maid as a status symbol. The protagonist Lin Xuan traveled through time and found that nine ancient animal spirit marks were sleeping in his body. Whenever he is close to death or suffers from severe emotional fluctuations, a mark will be awakened and a beast-eared girl will be summoned. But here comes the problem - these beast-eared girls are all powerful in ancient times. Now they have been sealed in the mark and slept for thousands of years. When they wake up, their cultivation level will be reduced, and they need to rely on the protagonist's aura to slowly recover. So while the protagonist is being chased by strong men from all walks of life (because the mark of the ancient beast spirit is the treasure that everyone covets), he leads a group of beast-eared girls who were "once awesome but now weak" to survive and upgrade to become stronger.
