During the three hundred years of Dajing, the country's fortunes were in decline, droughts and floods persisted, and rebellions broke out everywhere. Emperor Jing wields his sword and sends his iron cavalry, General Zhenyuan leads the elite Xuanjing Division to the west. Murderous intentions are hidden in the court hall, and the western border is at war.
In an unnamed village at the foot of Cangyun Mountain, seven-year-old naughty boy Lin Ye still doesn't know that troubled times are coming. He is giving the grasshoppers he has worked so hard to catch to his playmates, living a carefree life in the mountains and fields amid the warmth of his parents and Mr. Zhou's education. But he didn't know that the seemingly ordinary teacher at the head of the village hid a secret that could overturn the world; he didn't even know that the seven-day wind when he was born had already carved a destiny for him to become a fairy. When the iron hooves of the Western Expedition trample the tranquility of the village, and when the dark blade of the Xuanjing Division points to the countryside, this young man from the mountains will eventually transform from a childish boy into a world-shaking immortal. Amidst the overthrow of the dynasty and the strangeness of the immortal gate, he will find his own path to enlightenment.
