Princess Su Tang, who was miserably sacrificed as a sacrifice in her previous life, unexpectedly returned to the sedan chair after awakening the memory of the demon concubine with regret. This time she held the secret of demon taming, and while smiling, she dragged the prince and concubine who designed her into the Shura field of fantasy. While rubbing the soft belly of the nine-tailed prince who was pretending to be docile, little did he know that the squinting monster had already seen through her identity as a reborn person, and was just waiting to take her back to its lair to reveal the truth about the red thread of marriage she had personally tied for him a hundred years ago.
