Thirst: The desert castle

I didn't need sleep. 

My eyes felt slightly heavy but it was good. 

All I needed was a fresh source of blood. 

And there was plenty of blood here. 

But I had to remain content with just animals.

Now that I'd tasted demon blood though, I wanted more. Maybe things with intelligence had something different in their blood?

Or was it just mana?

Actually, if it was mana, that would explain how I felt supercharged after drinking blood. 

And I kind of wanted more. 

"Unless the next oasis has an abundant source of water, we'll have to dig into our rations and we'd barely make it," the kid came over to me. 

The sun was rising.

Many of the soldiers were sleeping peacefully. The rest were keeping watch.
