The world system is divided into nine grades, with Body Refining Realm, Ning Mai Realm, Gang Sha Realm as the lower three grades; Postnatal Realm, Innate Realm, Grandmaster Realm as the middle three realms, and the upper three realms are Five Qi Chaoyuan, Three Flowers Gathering at the Top, and Unity of Heaven and Man.
Furthermore, there is a realm above the nine grades, known as the God Demon Realm.
The special gene fragment that Gu Shanhai previously discovered from the human race is actually the legacy left by a cultivator who became a God Demon, benefiting his descendants.
If the God Demon is still alive or the bloodline concentration is sufficient, it will activate, possessing a physique of God Demon's offspring, meaning as long as resources are in place, cultivating to the Unity of Heaven and Man Realm is basically not a difficulty, but becoming a God Demon, for this type of physique born from a God Demon bloodline, the difficulty is akin to climbing the sky.
