Venerable Shangyun Yu Leng has lived for ten thousand years. He cultivates the ruthless way and never accepts disciples. Until the young man named Gu Changyan knelt in front of the mountain gate, his knees burning the bluestone, and his eyes as clear as the first snow in the mountains. He has mediocre qualifications and mixed spiritual roots. He is recognized as a waste in the world of immortality, but he knocked on her door with his obsession. No one knew that she kept him because of the dust-free piety in his eyes; no one knew that he never sought enlightenment just to ascend, but just to stay by her side. When Master Qing Leng's heartbeat changed his rhythm, the master-disciple bond that began with obsession finally touched everyone's heart.
