Mark of Blood

"Take this!" he shouted and came at me with his whole body covered in the thick bloody energy.

I am not looking at the energy, but at its sword, which had red runes appearing on it, with each one filled with so much power that it scared the shit out of me.

Seeing, I harnessed every bit of my power; squeezed every speck from my cells, and poured it into my veins and them to my sword.

I had been hiding some of my power and I hope, it will be enough to defend against this mighty attack. 

Which would be the strongest I had ever faced in my life.

He appeared in front of me in an instant and launched the attack, while my sword, which was already defensive, move, according to it.

It might be a mercy duel, but I didn't want him anywhere close to me. I need to defend his attack with my sword.
