[Sword Gourd Spirit] holds the possibility of Breaking the Realm, but he hasn't yet found the right method, or perhaps he simply hasn't accumulated enough.
"Maybe my Spiritual Power isn't strong enough, maybe the original 'Sword Gourd Journey' has a middle and lower volume..."
He has read thousands of books, but only 'Sword Gourd Journey' granted him the special ability of [Sword Gourd Spirit].
This suggests that ordinary books cannot grant abilities; only special books can, and 'Sword Gourd Journey' falls into this category.
The ability of [Sword Gourd Spirit] does not appear out of thin air; the travelogue 'Sword Gourd Journey' itself possesses a certain profundity beyond the grasp of ordinary people.
In other words, 'Sword Gourd Journey' may not be a mere travelogue but rather similar to a Cultivation Technique, composed of realms such as Blood Circulation, Strong Bone, Refining the Internal Organs, etc.
