The secret techniques others cultivate all originate from Secret Spirits, and corresponding Secret Realms are certain to exist.
However, the Secret Technique of One cultivated by Chen Guan is human-made, so whether a corresponding Secret Realm exists is hard to say.
Chen Guan has sensed for so long yet hasn't felt the existence of a Secret Realm, which seems to be a very bad omen.
If a corresponding Secret Realm doesn't exist at all, Chen Guan doesn't know how to continue advancing in his level.
Even if a corresponding Secret Realm exists, having sensed for so long with no feeling whatsoever, by normal theories, such a Secret Realm would likely belong to the weaker category of Secret Realms.
Having come this far, Chen Guan couldn't possibly give up now; he could only continue operating the Secret Technique of One, hoping to sense the corresponding Secret Realm.
