One hundred thousand years ago, an invasion from another realm left thousands of miles of barren land and countless lives in ruin! To protect all living beings in the world, the Great Emperor Lu Xuan ventured alone into the Heavenly Abyss, using his own body as a medium to seal the entrance to the other realm! Never did he expect that, one hundred thousand years later, he would suddenly receive a bloodline summons from his descendants! "Ancestor, are you still alive?" "If you don't return soon, the entire Lu family will be wiped out!" On this day, the Burial Heaven Divine Sword, sealed away for one hundred thousand years, reemerged into the world. The heavens wept blood, and ten thousand swords mourned! "I may be old, but I am not dead!" "A bunch of ungrateful wretches! How dare you expect this emperor to protect you!"
