Meridians Change
The changes taking place inside of his physical body was not anything life changing that suddenly increased the strength of his physical body another level. Instead, it was a more subtle change that slightly changed the meridians in his body.
The change in his meridians not only allowed his qi to flow more smoothly, but also allowed him to absorb the qi between heaven and earth faster!
Other than these two things, Xuan Hao also felt like something else had fundamentally changed, but he couldn't really grasp what it was. Looking through the system to find out what had happened, didn't really yield any results either.
But similar to the last time the feather imprint had absorbed something, he had also felt like his understanding of the world around him had increased. In essence, his comprehension speed had once again increased after the feather imprint had absorbed the blue divine energy.
