How could Fang Xiao not be interested in such a wondrous method? That would be a lie.
Even if his true body had no use for it.
One had to know that he still had the Taiyin Sun Incarnation twins at hand.
They did not possess the indestructible trait of Dao soldiers, which could be shaped at will.
Thus, though they were stronger than Dao soldiers, Fang Xiao had rarely sent them out.
He was worried they might fall elsewhere.
After all, the level of matters he now encountered was no longer something Void Refining Stage incarnations could handle.
But if they could cultivate the Yin-Yang Great Dao Song as well and master the method of Yin-Yang Mutual Generation...
Then, not only would the overall strength of the Taiyin Sun Incarnations rise by a minor realm,
they would no longer need to fear the danger of perishing.
As for the limits of their lifespan, they were not a problem at all.
One had to know that even without factoring in heaven and earth spiritual qi, True Spirits possessed nearly boundless lifespans.
And those with True Spirit bloodlines would, to a greater or lesser extent, inherit some of those traits.
Though the Taiyin Sun Incarnations' lifespans could never reach the level of True Spirits,
if calculated carefully, they were certainly no shorter-lived than ordinary human Body Integration Realm cultivators.
Moreover, as their cultivation continued to rise and their True Spirit bloodlines were continuously purified, their lifespan limits would rise as well.
"You want the complete inheritance of the Yin-Yang Great Dao Song?"
Within the Small World, Li Mobai looked at Fang Xiao with an odd expression.
Clearly, he knew nothing of the Taiyin Sun Incarnations and did not understand what Fang Xiao wanted this inheritance for.
Fang Xiao did not explain.
