The fox demon Mu Yanxi fell in love with the God of War in the heaven in her previous life, but was plotted and massacred by the immortal sect. Five hundred years later, Mu Yanxi was reincarnated into the human world. When she was born, it snowed heavily for three days in a row. Even the heaven was affected, and the gods were sent to the lower world to check. Gu Moqing felt Mu Yanxi's aura, and decided to jump off the reincarnation wheel in order to prevent the Emperor of Heaven from noticing that she had secretly descended to earth. She swore that she would protect her this time and not let her be harmed.
