Having problems with his meridians and thus rendered incapable of practicing the internal arts, Qin Yu lives in seclusion with Grandfather Lian. To cheer up a depressed Qin Yu, Lian gifts him a peculiar bird, which the former names Xiao Hei. Wanting to be recognized by his father, Qin Yu embarks on the path of cultivation. With Zhao Yunxing's rigorous training method, he strives to overcome his physiological hindrance and become an expert in the external arts. While resting from one such training session, Qin Yu discovers a red crystal that, to his surprise, fuses with his body. Unbeknownst to him, this subtle transformation gives Qin Yu astounding abilities that will aid him as he sets out, with Xiao Hei in tow, to prove that he is worthy of his father's acknowledgement.

Believing Qin Yu to be dead, his family sets out to avenge him; elsewhere, Qin Yu and Xiao Hei find themselves in an unfamiliar place. While adjusting to this new environment, they encounter a talking cat, which gives him a book with the answers to all his questions. With this book, he learns of Stellar Transformation, a mysterious cultivation method often mentioned in stories to children. Using this newfound technique, Qin Yu and Xiao Hei set out to the Boundless Ocean to further cultivate. Though their journey is not smooth, they gain new allies and reach new heights.

After reuniting with his brothers Hei Yu and Hou Fei, Qin Yu sets his eyes on the Immortal Manor. As Qin Yu possesses one of the nine Jade Swords that serves as a key to the mansion, an inevitable battle ensues with the Hall of Nine Demons and various other sects vying for the key. Despite the tumultuous road ahead, Qin Yu and his companion Jiang Li persist through various ordeals to obtain the treasures of the Immortal Manor.
