In the vast and mysterious world, the evil shadow of Netherworld Palace quietly shrouds. The master of the palace attempts to seize the protective sheaths scattered everywhere and awaken the ancestral witch's final form in order to realize his ambition to control the world. Lu Che, the protector of Northern Xinjiang, shouldered the mission of his family and the belief of protecting the common people. He formed an iron triangle with Tang Wuzhou, the elite of the secret hall, and Aman, the Miao Xinjiang voodoo girl, and embarked on an arduous journey against the Nether Palace.
They set out from the battle of the Ice Crystal Cage in the snowfields of northern Xinjiang. Faced with the fierce conflict between the power of rebirth and the ice soul of the ancestral witches, they successfully resolved the crisis with their tacit cooperation and tenacity. However, the master of the Netherworld Palace fled to the East China Sea in an attempt to seize the protective sheath guarded by the sharks. The three of them pursued him to the coast of the East China Sea without hesitation.
On the way to the secret land of the sharks, they encountered the singing of the sharks that can confuse the mind, and the dangerous reefs and shoals. After arriving in the secret realm, Lu Che gained the recognition of the spirit of the East China Sea through his profound understanding of the protective belief, awakening the new power of the protective sheath. But the arrival of the Lord of the Netherworld Hall triggered a thrilling and fierce battle. The blood moon rises, the remnant soul of the ancestral witch appears in the world, the sea water in the secret realm is polluted, and everyone is in dire straits.
In the face of powerful enemies, they never flinched, constantly exploring their potential in the battle, and fighting side by side with the sharks. From the tidal resonance against the ice crystal barrier, to the belief in protection to break the threat of the blood moon; from the emergency rescue of the eruption of the submarine volcano, to the life and death battle with the fragments of the Blood Sword in the ice abyss... Every battle is exciting, and every crisis tests their faith and friendship.
In this battle between protection and destruction, how will Lu Che, Tang Wuzhou and Aman overcome many difficulties? Protect
