Millions of years ago, the demons were defeated in the war between gods and demons. Cang Qi, the leader of all living beings, fell after the war. The gods were shattered and returned to Hongmeng, which is known in history as "Twilight of the Gods". Millions of years later, the divine flower that grew up in the ruins accidentally lost her heart when traveling across the Nine Provinces. She turned into a human and was born to search for her. However, because she was ignorant of the world, she fell into the devil's net and was refined into the strongest sword of the demon clan by the devil emperor who stayed up all night. After being defeated, the cowardly demons who have been huddled in the northern abyss for millions of years are bent on revenge. She is a god without divine blood, but she has become a demon. The immortals in the upper world watched the battle of Kyushu indifferently.
