Lu Xianshuang once severed his feelings with a regretful sword, vowing to become a stranger to Xie Jin for the rest of their lives. But on a night when blood stained the martial world, he discovered that the sword that had cut off their bond was, in fact, a cage forged by Xie Jin himself. He reforged the blade with his own heart’s blood, striking down the obsession of the past and kindling the warmth that had never quite died. Xie Jin hid in the shadows, his fingertips still stained with blood that had yet to dry from that night, but he no longer dared call him “Senior Brother.” The world said Lu Xianshuang had fallen to the demonic path. Only Xie Jin knew the blade had never been aimed at the world, but at the demon in his own heart.
