When the broken sword was reforged, the world was cold. Han Zhao was once the sharpest sword of the Sword Sect, able to cut rivers with one sword, but because his beloved Cen Xuici was killed by the sect, he abandoned his sword and became a demon. Seven years later, he returned with the broken sword. The sword was not out of its sheath, and his murderous intent was stained with frost. Cen Xueci was not dead, but was imprisoned in the northern ice prison. He was burdened with an ancient blood curse and could split mountains and rivers with just one word. The two met again, but before the sword was drawn, their love was over. People in the world say they deserve to die, but when Han Zhao feeds the sword with blood, and Cen Xueci uses his life to burn the curse, the point of the sword's edge is not the enemy, but the man-eating world itself.
