The fragrance of wood shavings in Qingwa Village hides the most exquisite woodworking skills in the world. Every piece of furniture carved by Carpenter Shen seems to contain life, and the bite of the mortise and tenon is his endless pursuit of craftsmanship. However, a fragrant sandalwood box broke his peaceful life. When the richly dressed old man appeared with a mysterious commission, and when the secrets hidden in the restoration process gradually emerged, Carpenter Shen embarked on a thrilling journey across rivers, lakes and ancient tombs.
As the secrets of the sandalwood box were revealed layer by layer, Carpenter Shen found that he was involved in the Xuanyin Sect's huge conspiracy to seek immortality and subvert the world. The traps in the ancient tombs and the disputes between good and evil in the rivers and lakes could not stop him from exploring the truth. In the process, he accidentally obtained the mysterious power of heaven, reunited with his uncle who had been missing for many years, integrated carpentry into martial arts, and created the unique "Eighteen Styles of Heavenly Craftsmanship", and launched a life-and-death showdown with evil forces on the top of Songshan Mountain.
After a near-death experience, Carpenter Shen could have retired to his countryside, but because of his unwavering ingenuity, he recruited apprentices to teach his skills and established the "Tiangong Sect". New crises followed one after another, and the Xuanyin Sect made a comeback, coveting the secrets of the ancient "Tianji Pavilion". Carpenter Shen led his apprentices to embark on another journey. In the process of cracking numerous mechanisms and fighting against evil forces, they finally realized the true meaning of the power of heaven - that is the spirit of the craftsman resonating with the heaven and earth, and the belief in using craftsmanship to protect the world.
