One thousand strands was the standard for a breakthrough. If he wanted to cultivate to the peak of the Core Formation Third Layer, he needed a full upper limit of three thousand strands of magic power. For him, that was not too difficult.
The Dual Placement Slots gave him "5 strands/day," and with his own cultivation speed plus the effects of the Ten Thousand Year Profound Ice Bed, it would only take a little over three hundred days.
In other words, at most one year.
Then he could consider breaking through to Mid-stage Core Formation. If he had no Breakthrough Pill, he could grind away for a few months and break through; with one, it would be even faster.
This kind of speed gave him the thrill of returning to when he had cultivated in the early Qi Refining stage. Back then, a few days meant one minor realm—both arduous and pleasurable.
"So this is a Heavenly Spiritual Root!"
Speaking of which, his Divine Sense had been the first to break through to Third Tier, then his body refinement, and only last had been his fundamental cultivation.
After his Divine Sense broke through to Third Tier Mid-Stage, because he lacked soul-refining resources, his progress had slowed. He could only obediently absorb Heaven and Earth Essence to increase it.
As for his body refinement cultivation being stuck at Third Tier Early Stage, that was also due to a lack of body refinement resources. It was even slower; he could only absorb Grand Yin Moon Fiend Energy to refine his body. Divine Marrow provided ample tempering, but insufficient nourishment.
The Body Refinement Dao relied even more on replenishment from external spiritual objects. Otherwise, it was just like this—slow as a tortoise crawling!
These problems were difficult for Wang Yu to solve in
