Very soon, Li Yuan sensed a peculiar fluctuation entering his Inner Universe Realm.
He did not resist it, so the special fluctuation was quickly accepted by the primordial source of his Inner Universe Realm.
Like the Divine Emperors who control the Universe Realm, they can refine a Universe Realm Sacred Spirit within their Inner Universe Realm...
The Universe Realm Sacred Spirit, at its weakest, is generally at the threshold strength of a Divine King.
For example, Star Elder or the purple giant beast of the Ancient Universe Realm are of this level.
The strongest, in theory, can reach the level of a Divine Emperor, though such cases are extremely rare.
“Refining.”
“My Inner Universe Realm primordial source, at the moment, can only nurture a single Universe Realm Sacred Spirit?” Li Yuan pondered.
His Inner Universe Realm was quite perfected, surpassing that of many Divine Kings’ Inner Worlds.
But Li Yuan himself was only at the ‘Celestial God Realm,’ and the power of his Inner Universe Realm’s primordial source was limited, so for now it could only refine the weakest Universe Realm Sacred Spirit.
“Fusion.”
Under Li Yuan’s guidance, this sliver of consciousness from the Little Tomb quickly sunk into the deepest part of his Inner Universe Realm, beginning to merge with the purest life substance there.
