A Breeze Along the Path to Immortality is a fantasy novel blending xianxia, science fiction, and reincarnation. The story follows Lu Qingfeng, who is actually the reincarnation of three people: the ancient Azure Emperor, Earth scientist Ouyang Qing, and Qingfeng, a disciple of the Supreme Immortal Sect. Born into the Lu family in the Bone-Eroding Demon Forest, he possesses a mysterious jade leaf and a spiritual intelligence core called “Xiaoxin.” Though born with a Daoist body, his cultivation has stalled because his soul is incomplete. To help him break through the bottleneck, his parents risk using a Soul-Eater Demon Crystal, accidentally triggering a phantom image of the Azure Emperor's battle armor and a message from the Purple Mist Sect Master, the reincarnation of the Nine Heavens Goddess. The message foretells that he will form a golden core on his own at age fifteen.
As Lu Qingfeng grows, he gradually awakens the memories and powers of his past lives, repairs the Azure Emperor's battle armor, and discovers that the world has been transformed by the invasion of a demonic tide. The Supreme Research Institute uses demon crystal and demon-suppressing herb technology to turn the tide, and Lu Qingfeng's contributions earn him a controlling stake in a demon crystal energy company. To investigate the disappearance of Senior Sister Ziyan and deal with infighting within the sect, he heads to the academy of the Six Harmonies Immortal Sect, meeting the Buddhist son Hanming and the dragon-clan assassin Ye Wuchen along the way.
At the academy, Lu Qingfeng faces a trial set by Jiang Lan, deputy dean of the Heavenly Secrets Institute. In a secret chamber, he revisits memories of his past lives and confronts an attack by the Lord of the Void, who uses Ziyan's demon-corrupted half-soul. Using his “Eagle Catches the Chickens” plan, he joins forces with the academy's grand formation and intelligent System to successfully imprison the Lord of the Void's will. He also reveals that Ziyan infiltrated the demon realm to obtain “Void's Milk” and hatch their “Daoist Embryo Egg.” The story reaches a climax as Lu Qingfeng simulates the Azure Emperor's battle armor to unleash a suicidal strike, laying the groundwork for even more complex plots and battles to come.
