Three hundred years ago, Demon Venerable Si Fanyin of the Three Realms was pierced through the heart and killed by the person she loved most, Immortal Venerable Jun Ling of Tianyan. Reborn in a new lifetime, she is reduced to a dust-realm good-for-nothing without any spiritual power in Qingzhou. To seek the truth and find the three dragon eggs entrusted to Jun Ling back then, she takes Lu Zhao's recommendation, enters the Tianyan Sect headed by Jun Ling under the alias "Fan Le", and lies low as an outer sect good-for-nothing disciple, stepping closer and closer to the secluded Xuanxiao Peak to gradually tear apart all the conspiracies covered up back then.
