The demon lord tells his sister that the nine-layer deathlands were once a battlefield where the demon clan fought with the human race. Many human lives were lost, and the remains of those who were killed were also found. He also tells her that he has found the soul mirror, which can absorb soul and maintain one's state without destroying it. He says that he does not need it, but that he needs to reach heavenly rank first. He thanks his sister for the gift, and says he will keep it safe. He tells the demon lord that he will pay a visit to the boy who defeated him, and that the boy will definitely join the divine feather selection. He adds that if the master of the divine feathers is not an idiot, he will definitely choose him as his disciple
