The tiger spirit Sanniang married Gu Yunsheng, a mortal, to repay her kindness, hoping that she would be among the immortals after he returned to the West a hundred years ago. Unexpectedly, Gu Yunsheng was still in good health at the age of 100. The descendants of the Xu family also coveted the ancestral home, and even the vixen next door was eyeing his yang. For a hundred years, Sanniang tried every possible means, even using strong medicine to try to make him "unreplenished", but failed repeatedly. She also found that Gu Yunsheng could always protect her in critical moments. It wasn't until she sneaked into the study and discovered the secret that she realized that Gu Yunsheng was the painter she had rescued three hundred years ago. He had known her true identity from the wedding night. That casual phrase "Huahua" actually hid his thoughts for a hundred years.
