'I'm 50 now, huh? 'Gravis thought with a disconnected and surreal feeling. 50 had always seemed kind of old to Gravis, but now that he was 50, he didn't feel that old. However, Gravis also remembered that if he compared his age to his longevity, it could be compared to him only being five years old. For mortal standards, he was old, but for cultivation standards, he was incredibly young.
Nearly no one reached the Unity Realm by going through the Self Stage before the age of 60. The ones able to reach it way sooner were either from higher worlds or were incredibly rare. Additionally, Gravis was about to reach the Nascent Nourishing Realm.
Reaching the Nascent Nourishing Realm in such a short amount of time was also quite outstanding, though not as outstanding as reaching the Unity Realm in his 20s. For humans, there were no bottlenecks between the Unity Realm and Nascent Nourishing Realm. Therefore, humans could also reach that Realm in a short time.
