Now an adult, Fang Ling descends to the mortal world to fully merge the demon heart and break his cultivation limits. On his journey, he meets his true love, and their romance fuels his cultivation. His power grows steadily until he returns with supernatural strength to slay his enemies and complete his revenge.
