The ancient goddess Nüyou once helped the Yellow Emperor fight Chiyou, used divine fire to drive away the Feng Boyu Master, and saved all people from the wilderness. However, after the war, her magical power was out of control, and she traveled thousands of miles across the land, and was called "Drought Demon" by the world. In order to prevent the common people from suffering another catastrophe, the Butterfly Clan and the Shouto Clan joined forces to suppress them at the bottom of the Yangtze River, and made a covenant: if the Drought Demon reappears, the butterfly seals of the two tribes will resonate to warn. Thousands of years later, Dou Yuheng, a descendant of the Shouteng tribe, and Yingxi, the princess of the Butterfly Kingdom, sensed the butterfly mark in their palms at the same time as a warning. At the same time, news came that King Jiangling was hunting butterflies - his Princess Xina was suffering from a strange disease and needed to use butterfly wing scale powder as medicine. Yingxi, Dou Yuheng and others rushed to Jiangling, and they went through dangers side by side, and gradually fell in love. The two teamed up to fight against the enemy in the wilderness. After tracing the seal, the ancient tree spirit was shocked to find that the concubine who had suppressed her for thousands of years had already escaped, and the Princess of Jiangling was probably transformed by the concubine. Although the Butterfly Clan and the Shoudeng Clan had been sealed to her, they also used living water and vitality to help Nuwa suppress the divine fire. But the long loneliness and resentment have already penetrated deep into the bone marrow. She designed to attract the descendants of the Butterfly clan and Shouto, just to seize the vitality of the Butterfly clan and the spiritual power of Shouto, and return to the heaven. In the Butterfly Kingdom, the Xuan Sheng tree bears a fruit every hundred years, and its fruit can strengthen the immortal body and reverse the vitality. Yingxi advocated using the Xuan Sheng Fruit and the power of the two clans to help Nu Xi return to the heaven in order to resolve the thousand-year grudges. On the stage of questioning, Nu Xi finally swore not to harm the descendants of the Butterfly Clan and Shou Teng again. However, the King of Jiangling, who was greedy for immortality and power, suddenly seized the Xuansheng Fruit and swallowed it, but was attacked by the Wenxintai. Under the combination of the butterfly seals of Yingxi and Dou Yuheng, the living water of Shou Teng blended with the vitality of the butterfly clan, and the concubine finally suppressed the thousand-year divine fire and ascended to the sky. Yingxi and Dou Yuheng also made a life-and-death vow to stay together based on the butterfly seal.
Intention: The "evil" that has been misunderstood by the world for thousands of years was once a god who sacrificed his life to save the world; love and benevolence can finally dissolve the hatred of thousands of years.
