At the age of sixteen, Liu Chuan, the master of swordsmanship, died on the battlefield of the Upper Three Realms. That night, Liu's accusation of treason spread throughout the world; before Liu's bones were cold, a monument of sin was already erected outside the human city gate. In the Northern Wasteland of the Lower Three Realms, late at night when the mine valley collapsed, a young man woke up from under the rocks. The bones and blood are as good as decay, but there is an old seal that cannot be revealed. Some people are searching for extraterrestrial relics in the lower realm, while others are rummaging through old battlefields for a dead man in the upper realm. Liu Chuan could only practice his first breath again from the body tempering realm, and in the midst of the mineral dust, blood, and pursuit, he could hold the sword back in his hand. When the sword intention was unsheathed again, what he wanted to ask was not just why the Liu family was destroyed. Who wrote the traitors into the history books, and who survived that night to this day?
