The cracking sound of bones echoed sharply within the cave, but surprisingly, Tang San didn't feel any pain throughout the process. The cool blue current was acting directly upon the meridians throughout his body.
Tang San was astonished to see that all of his meridians had turned a faint blue. The space within his meridians for the flow of Inner Strength had increased by several multiples.
The stream gradually became a vast river, yet the meridians did not thin out, but instead became even tougher and more resilient.
If two years of tempering under the waterfall had polished Tang San's bones and allowed him to completely absorb the effects of the "Octagon Frozen Grass" and the "Blazing Apricot Cabbage" two immortal grasses, then now, this hundred-thousand-year-right leg bone of the Bluesilver Emperor expanded Tang San's meridians to their limits. The perfectly neutral energy cemented the effects of the two immortal grasses perfectly.
