Although the Spiritual Power each cultivator needed for Core Formation differed, there was a rough average.
Above that average, they would be stronger after Core Formation; below it, even if they successfully formed their core, they would be relatively weak.
The feeling of watching his cultivation visibly advance was truly intoxicating.
Song Yan had not wanted to stop, but after thinking it over, he still did not know what special effects refining a Spiritual Source treasure would bring, so he decided to begin incorporating Jiafeng first.
There were at least seven years until the Immortal Tomb next opened. He had plenty of time to cultivate.
He took the ancient books and secret records concerning Spiritual Source treasures out of his Heaven and Earth Bag and began reading them one volume at a time.
Any single volume might contain little information, but cross-referencing them yielded much more.
"So Spiritual Source treasures aren't limited to the five elements-"
One book mentioned that besides the five elements, there were also said to be wind, lightning, poison, and even sun and moon Spiritual Sources.
Those were simply even harder to find.
Different Spiritual Sources of the same nature produced much the same effects after incorporation. There were only minute differences depending on whether they were innate, acquired, or derivative, differences that could practically be ignored.
In fact, after a Wood-Element Spiritual Source was refined into the body, the wood-element Spiritual Power within would surge for a short time. Unfortunately, Song Yan had no wood-element Spiritual Power in his body.
He had not paid much attention at the time. Perhaps that had been the portion continuously converted into Sword Qi.
That would explain what had happened then.
Unlike the last time, when he had swallowed the wood whole, he had come prepared this time.
