"Do you mean that this is how things appear from the outside, but there's actually a hidden Demon-Sealing Secret Realm within? I wonder what grade of spirit beast this Spiritflame Goddess is?" I hurriedly asked, though in my heart, I already understood the origin of the matter. I had originally said that the fire spirit beast in the Demon-Sealing Secret Realm must be related to this cultivation method, but I hadn't expected that this method actually came from a humanoid spirit beast. I would have to look at it from another angle.
"Transcendent-grade one. That's why the successive Lords of the Immortal-Tilting Manor kept this secret hidden, allowing it to spread only through the mouths of the manor lord and the grand elder. Of course, Brother Dongren isn't an outsider, so there's no need to hide it from you." Nan Jin said.
"Transcendent-grade one... Then how many people in the entire Immortal-Tilting Manor cultivate this method?" I felt a faint sense of unease.
"Only me. The ancestors of the Immortal-Tilting Manor established a rule that this cultivation method and the Demon-Sealing Secret Realm could not be used unless the Sacrificial Immortal Blood Crossing was about to begin and tremendous power was needed to contend for the Sacrificial Immortal Platform. Only then could the secret realm be opened and its spirit manifested. Moreover, the greatest condition was that in each generation of the Immortal-Tilting Manor, only one woman could exist who cultivated this method, and she also had to be related by blood to the manor lord. So after searching again and again, only I, his daughter, met the requirements of age and timing well enough. That's why I was lucky enough to become the inheritor who obtained this cultivation method during this sixty-year cycle." Nan Jin spoke with unmistakable pride.
