Lin Xiao, the young master of Linjiabao in Jiangnan, suddenly suffered a tragedy when he was six years old. Fortunately, he was rescued by the Shaolin monk Huiyuan and lived incognito in the Shaolin Temple for twelve years. When he came of age, he learned from the master that the downfall of his family was closely related to the lost "Netherworld Sword Manual". The jade pendant with strange patterns engraved on half of his neck was the key to uncovering the truth. With the flame of revenge in mind, Lin Xiao stepped into the turbulent world.
On the way down the mountain, he rescued Su Yao, a descendant of Yaowang Valley who was besieged by bandits. He unexpectedly discovered that the jade pendants in their hands could fit together perfectly, revealing a map pointing to the mysterious valley, where the "Netherworld Sword Manual" was suspected to be hidden. At the same time, various forces such as Shen Qianjue, the leader of the Nether Sect, and the Blood Knife Sect took action upon hearing the news, and a bloody storm began surrounding the sword manual and jade pendant.
On the road to pursuing the truth, Lin Xiao and Su Yao worked hand in hand, cracked numerous mechanisms, and experienced life and death struggles. Can they uncover the shocking secret behind the jade pendant and find the sword manual to avenge Lin Jiabao? And what kind of conspiracies and crises are waiting for them in the dark corners of the world?
