The Legend of Paladin Sword

Nineteen years ago, the Qionghua Sect used the double swords of Wangshu and Xihe to trap the demon realm and seize spiritual power, triggering a war between humans and demons, with heavy casualties on both sides. Due to their disagreement with the Qionghua Sect's cultivation philosophy, the disciples of the Qionghua Sect, Yun Tian Qing and Su Yu, left Qionghua and went to Qingluan Peak, where they gave birth to their son Yun Tian He. Not long after, Su Yu passed away.
