The Holy Maiden of the Demon Sect Is so Bad, I Love It so Much

[Single female protagonist + fun fighting + decisive killing + slow growth + traditional fantasy + female protagonist's crazy teasing + female protagonist gradually giving away + no system + both male and female protagonists are slightly sickly in the later stage] At a cocktail party, Wu Yuan, who was traveling to Yuanling Continent, encountered the incident of a demon girl abducting a good man and woman. The charming girl showed a ruthlessness and charm that frightened Wu Yuan. Seeing that the other party was about to leave, Wu Yuan waved in an uncontrollable manner. Unexpectedly, the enchantress raised her eyes and spat, "It's too yin, don't want it." Just when Wu Yuan was dumbfounded, this evil witch bent over with a smile on her lips. In order to survive in this crisis-ridden world, and to become stronger, Wu Yuan competed with the geniuses of various major forces, and fought against the enchantress... Many years later, Wu Yuan became the emperor in charge of life and death, and took the duplicitous witch into his arms. —— There are daily routines, but the main theme is the story of the protagonist becoming stronger, growing up and capturing the heart of the heroine in the middle. If the introduction is insufficient, please move to the text. Lightning protection: The heroine doesn't like the hero at first, but because of the skills she has practiced, she slowly teases him and then gradually gives him away. You don't have to fall in love with the other person from the beginning. If you don't like the other person, don't complain. The battle scenes will gradually become more exciting later on, and the female protagonist will have many roles from beginning to end.
