The only way for him to get his blood was by advancing in his cultivation realm. With each advancement came an upgrade, however with the chains in his body, advancing to a level was like ascending the heaven steps.
So, given the red sword his blood, he was killing himself.
The red sword seemed to have known what was going on in Devon's mind as it shook its body, "DON'T YOU DARE!!!!!!" The angry voice of the red sword rang out.
Devon smirked, he couldn't find any reason in arguing with the red sword. His blood was his and if he didn't want to give anyone, not even the gods and devils can make him change his decision. "Why is the primordial chaos energy in my body flawed?" Devon asked the still trembling sword.
He had given out his blood, so he needed to get his answers.
