At top speed, he memorized every last bit of content on the stone stele, engraving it into his heart without missing a single word.
Letting out a long breath, Li Su's expression relaxed considerably as the weight in his heart finally lifted.
And as he fully comprehended the Celestial Human Scripture, he immediately discovered that subtle changes were taking place within his body.
They were not extensive, but they were exceedingly clear.
His body was being altered. The contents of the Celestial Human Scripture flowed forth from his primordial spirit, naturally merging into his flesh.

Supreme Flesh and the Nine-Nine Profound Art.
Both were trembling. Because of the Celestial Human Scripture, they underwent faint, inexplicable changes that began in his marrow and slowly spread outward.
His mana was being consumed as well, though only to such a slight extent that it could almost be ignored.
Much like Nether Script, the Celestial Human Scripture was transforming his physical body, rewriting it on a profound level, reaching all the way down to its very components.
In only a moment, he sensed the difference. A special power was being nurtured within him.
Supreme Flesh and the Nine-Nine Profound Art were both adjusting, forming pathways compatible with the circulation of the Celestial Human Scripture and accelerating its completion.
