The Peerless Empress Became My Contracted Partner

In his previous life, Shen Yuan's family was wiped out by the Empress. After twenty years of bitter cultivation, he attempted to assassinate her but failed and died. He was reborn at the age of sixteen. He ambushed her at the Burial Immortal Abyss in advance, striking when the Empress was severely wounded and near death, only to find that the Great Emperor's body was impervious to blades, and an ant could not break through a true dragon's defense. In despair, he activated the ancient forbidden art "Chaos Symbiosis Contract," forcibly binding his life to the Empress's, so that they could never be more than a hundred li apart. One is a vengeful avenger, the other a domineering and aloof ancient Empress. They go from mutual threats to limited cooperation, from mortal enemies to kindred spirits. When the truth behind the massacre is revealed, they discover that both were pawns of the Heavenly Dao enforcers. The contract transforms from a shackle into a bond, and together they shatter the old order, rebuilding a free new world. — Description from novelcodex.org
