Nangong Heyao, the most disliked ninth prince of the Dayu Dynasty, was a romantic by nature but was repeatedly rejected for marriage, and was ridiculed as a "libertine" by the world. However, he unexpectedly awakens the "Love Saint Emperor System". As long as he captures the most beautiful woman, he can obtain luck points and exchange them for magical weapons and peerless martial arts. What's even more outrageous is that his natal artifact "Acacia Cauldron" is actually a proud and arrogant weapon spirit with a temper. He thinks that the host is too carefree, and will stop or even reverse the operation at every turn. Faced with the jealous and aggressive princelings, Nangong Heyao, while dealing with the harem and the beauties of the previous dynasty, used true love (or routine) to win over the hearts of the princes, while controlling the eccentric artifact to make changes in the court. From the ridiculed good-for-nothing prince to the eternal love emperor of all nations, let's see how Nangong Heyao holds a beauty in his left hand and holds a divine weapon in his right hand. He enters the Tao with "love" and reaches the top, leaving his envious competitors to look up in despair.
