I'm Really a Pet Doctor

This is a pet doctor in the context of the 21st century. After cultivating, he uses the cultivator's ability and combines it with modern medical knowledge to create a brand new medical system. By the way, there is a spark of love with a giant panda with the body of a demon (this love author is trying hard to make it happen). The heroine has a strong background, but she was raised poor and has a timid personality. The male protagonist was a bit childish when he first transformed, but he gradually became mature later on.
