Duan Qingxu is the senior brother of the Xuanqing Sect, and he joins other sects in fighting against the evil cultivator. Pei Ling, the founder of the evil cultivator, was originally the senior senior brother of the Lingxiao Sect, the strongest sect in the world of immortality. Because he failed to overcome the tribulation, he was unwilling to fall.
Intention: Both parties clearly love each other deeply, but they can't tell it.
