Sun Weiyan, a modern female nun, travels to another world due to unresolved fate. By chance, she and a fox demon possess the body of the Prime Minister's concubine, the idiot Zhou Yuning. After being rejected by the prince for her peerless beauty, she becomes Princess Buddha. She is good at poetry and governing the country. Her intelligence is praised by the emperor. Unexpectedly, the tragedy has just begun. When he was the prince, she was the princess. When he ascended to the throne with her help, she was not the queen. She was abandoned by him and left to be abused. He flattered me again and again and took advantage of me again and again. She sacrificed everything for him, using her essence to save his and his love rival's daughter, even sacrificing the child in her belly, destroying her own soul to save her love rival, but all she got in exchange was a bowl of poison and betrayal. She thought this was fate, her doom. Little did she know that three generations of love and three lifetimes of despair were just a conspiracy to make her destroy her soul... Everything was due to the prophecy: After the gods and demons, the soul will be reborn, with boundless magic power, subverting the three realms. After her rebirth, she began to practice, became a famous teacher, became the chief disciple, picked up some artifacts, and tamed some divine beasts. Her light is dazzling, and she has many admirers, but she is no longer the kind-hearted Sun Weiyan who only accepts anger. Love, sorry, she has no love; conscience, sorry, she has no intention; she is cold, unfeeling, suspicious, and unruly. She said: Those who obey me will prosper, and those who go against me will perish. "Since the Three Realms cannot tolerate me, I will destroy the Three Realms!" And where should her love go?
