The white-haired boy is a human, not a humanoid Secret Spirit, which is quite easy to differentiate.
However, humans under eighteen cannot enter the Secret Realm, let alone reach the Grotto Heaven Secret Realm.
This white-haired boy appears to be merely seven or eight years old.
Such a situation leaves only one possibility; unless he is a human born in the Grotto Heaven Secret Realm itself, that's the only way he could be here.
Human cultivators can give birth within the Secret Realm, and long ago, humans were already giving birth in the Grotto Heaven Secret Realm.
Children born in the Secret Realm often have physical talents and abilities different from ordinary people; they may even be born with innate talents and levels from birth.
Children born in the Grotto Heaven Secret Realm are naturally at the Fourth Awakening level, which is incomparable to children born outside.
