"The story of "Sword and Fairy 3" takes place fifty years before the first generation of "Sword and Fairy". At that time, Li Sisan was just letting out the first cry of a newborn; the Witch Queen was still an infant in swaddling clothes, and the Sword Saint had not yet entered Mount Shu to cultivate immortality... The cause of the events began with the sudden collapse of the top of the Demon Lock Pagoda and the unsealing of the seal. However, the deeper causes can be traced back to the divine realm a thousand years ago. General Fei Peng from the divine realm and General Chonglou from the demon realm frequently clashed due to conflicts between the two realms. They were evenly matched and gradually developed mutual respect for each other's abilities. Chonglou proposed to duel Fei Peng in a newly discovered fairy realm to determine superiority. Fei Peng hesitated due to the heavenly rules of the divine realm but ultimately succumbed to Chonglou's enticement and agreed. The evenly matched duel lasted for a long time and eventually drew the attention of the celestial court. Emperor Tian dispatched troops to capture Fei Peng and hold him accountable. Fei Peng, distracted by sensing the impending pursuit, lost his sword to Chonglou and was defeated... Time passed, and Fei Peng was punished by the divine realm and demoted to human form. After many reincarnations, he became Jing Tian, a shop assistant at Xin'an Pawnshop under the Tang family in Yuzhou. Meanwhile, Chonglou spied on the human world from the demon realm and accidentally discovered Fei Peng's humble and ordinary reincarnation. He conceived the idea to help Jing Tian and thus came to the human world, disturbing Mount Shu, intending to help Fei Peng retrieve his sword. Inadvertently, he destroyed the Demon Lock Pagoda and accidentally obtained the demonic sword cast by Fei Peng's first incarnation in the human world - Crown Prince Long Yang of the Jiang State. When Jing Tian obtained the demonic sword, he met Xuejian, the young miss of the Tang family, which changed his life. Initially caught up in the internal struggles of Xuejian's family and the conflict between the Tang family and Pili Hall, he later encountered Changqing, the exiled disciple of Mount Shu, and Zixuan, Changqing's fiancée. Thus, he embarked on a long journey to assist Mount Shu in finding the Five Spirit Pearls and resealing the Demon Lock Pagoda. The ghost hidden within the demonic sword manifested itself as Long Kui, Jing Tian's previous life and sister of Long Yang. The intertwined love affairs and repeated separations and reunions among these individuals unfolded amidst the survival struggle between humans and demons. In fact, human desires are the root cause of all disputes."
