An artery is a hollow blood vessel.
This simple explanation allows one to understand why an artery, built layer upon layer, is practically useless.
Fengyu knew this from the start but had no other option than to heal it like this.
If he healed the whole artery right away, he could already imagine the difficulty in doing so. Each little millimetre would have to consider the whole radius of the artery, the weight would be higher, the possibility for deformities would be extremely high...
'Deformities-' a light lit up in his eyes when he looked at the healed artery in front of him.
'When I healed this artery, I thought it would be easier. As long as I made sure the main artery had no significant difference to the previous artery, there would be no issue. But when I opened up the artery layers around it, I somehow felt a hidden vitality inside the artery I just healed, assisting the recovery...'
His mind jumped from one matter to another, a sense of confusion welling in his mind.
