This is why there are still some "Unparalleled Heavenly Child" in the world, but a "Son of Heaven" or "Heavenly Girl" with an "Innate Taoist Body" might not appear even once in tens of thousands of years.
Throughout the generations, whether Immortal Emperors and Immortal Supremes, or Demon Emperors and Demon Lords, they basically only reached the level of "Son of Heaven" and "Heavenly Girl" after inheriting the Immortal Scripture (True Demon Sutra) and improving their Bloodline Talent.
Furthermore, along their journey, they used every available bloodline improvement item, then supplemented it with the true scripture inheritance, only to barely push towards the True Immortal Realm and True Devil Realm.
This has resulted in, since the time of Divine Martial, the inheritance of strong individuals in the True Immortal Realm and True Devil Realm never breaking completely, but almost none have broken through to the Mid Stage.
