Civilized Key Keeper

Xiao Han, an abandoned disciple of Beichen Sword Sect, is a wandering prodigal in the world. He originally thought that his destiny in life was to use the sword in his hand to wash away the injustice. Until he met Lin Suxin, who possessed the "Secret Key to Starfall", and was involved in a storm that swept the world. The ancient prophecy is coming true. The shadow of the demon outside the territory is quietly shrouding the world. A terrorist organization called "Hidden Mirror Pavilion" is rampant in the world. Behind it is a mysterious force that attempts to devour the origin of this world. Only by awakening the power of civilization sleeping in ancient skills can we compete with it. When the silhouette of the shadow play turned into a sharp blade that cut off reality, when the roar of Huayin's old tune became a war drum that shattered evil spirits, when the carpenter's mortise and tenon built a barrier to protect the mountains and rivers... Xiao Han discovered that what he was guarding was not only Lin Suxin, but also the fire of the entire civilization. He is the last "key keeper", and the secret key in Lin Suxin's hand is the fire that ignited it all. With the shadow demon Rakshasa chasing him before and the world misunderstanding behind him, Xiao Han could only use his sword as a pen and blood as ink to write a legend belonging to the SSS-level intangible cultural heritage on this scroll of rivers and lakes!
