Lei Ling was originally a protector of the Jianghu sect Haiqing Gang. Because the gang leader offended cultivators, the Haiqing Gang fell apart. Yu Bingyao, the gang leader's daughter who had been betrothed to him since childhood, decided to embark on the path of immortality for revenge. Lei Ling protected her, traveling over mountains and through rivers, overcoming all the hardships along the way, until Yu Bingyao was eventually noticed by the Supreme Elder of the Zihong Sect for possessing the Heavenly Spiritual Root and was accepted as a personal disciple. As for Lei Ling, he became the karma that she needed to sever the moment she stepped into the Zihong Sect. However, an accident caused Lei Ling to awaken the thunder attribute mutated spiritual root. Not only that, but he also obtained a mysterious space capable of copying cultivation resources tenfold.
