The "spirit guide" circulated through his entire body.
As time passed, Wei Tu's "First Spirit Bone" gradually transformed, taking on a jade-like quality.
Moreover, dense Ancient True-Spirit Characters, as tiny as flies and insects, appeared upon the First Spirit Bone, shimmering with flowing radiance.
If a cultivator were to peer in from outside, they would see that Wei Tu's First Spirit Bone, inscribed with countless Ancient True-Spirit Characters, was nurturing an irregular "rune."
The rune was twisted and complex. It appeared no different from the runes commonly seen in the cultivation world, yet once one looked away, everything concerning it immediately vanished from one's mind.
There was no other reason. This was the most core treasure within the "True-Spirit Immortal Bone"—the "Innate Treasure Talisman"!
This Innate Treasure Talisman was Wei Tu's own Dao, much like the "artificial laws" created by Integrated Body Great Talents through immense magical power.
It was also an inseparable treasure within a true-spirit bloodline.
Pure-blooded descendants merely inherited a true spirit's bloodline and could not yet be considered "true-spirit blood descendants." Only those like the Blood-Winged Mo, who had inherited that true spirit's "True-Spirit Immortal Bone" and nurtured their ancestor's "Innate Treasure Talisman" within it, could truly be called "true-spirit blood descendants."
Naturally, Wei Tu's "Innate Treasure Talisman" was still only in its embryonic form. It remained far from artificial laws such as the "Spirit Zombie Law," and would only become comparable to them once Wei Tu reached the seventh tier of body refinement.
However, mastering this "Innate Treasure Talisman" at the sixth tier of body refinement was undoubtedly of enormous benefit to a cultivator like Wei Tu, who cultivated both Dharma and body.
Because he had already come into contact with—and gained control over—"laws" in advance!
