There was once a man who married her despite the opposition of the three realms. Even if he bows his head and surrenders, he still can't escape the Celestial Clan's conspiracy. On the wedding day, blood flowed like a river, and Shanxiu, the son of the Demon King, was wiped out in ashes. On the wedding day, the heaven was in chaos, and the emperor's daughter, Princess Chatuo, turned immortal into a demon. In an instant, the demon clan was destroyed, and Princess Chatuo lost her soul under the suppression of Buddha. Thousands of years have passed, and the two have become taboos in the three realms, and no one dares to mention them. "Shan Xiu, I am covered with thorns and come here for you. This time I will protect your eternal life." Ten thousand years later, Princess Chatuo met her beloved again. Will he retreat into the mountains and forests, or seek revenge for killing her husband thousands of years ago?
