The immortal god Xie Yanzhi picked up the demon singer A Ruo who was wearing half a blood jade on the demon-slaying battlefield. The red line on his wrist coincided with the broken sword scar on his heart - that was the mark where he blocked the soul-killing arrow for her thousands of years ago. When A Ruo turned into ice crystals on the night of the new moon, the memory fragments pieced together the shocking truth: the war between immortals and demons was actually Heaven's hunt for twin souls, and the prayers of ordinary people were the key to breaking the curse. Xie Yanzhi held her increasingly transparent hand, and against the rules of heaven and earth, he carved his last love letter in the heart-burning fire: "You are the half of my stolen soul. Even if you fall into the world, I will rewrite the way of heaven for you."
