On the second floor, in the animal room, Duke finished feeding Little Dou a piece of Toad-Wolf Beast jerky and began his daily blood refining cultivation.
That 1-Ring Spirit Beast—the Toad-Wolf Beast—had been enough to feed both him and Little Dou until now.

Little Dou yawned and lay down in its nest, which was lined with soft cotton padding.
Whenever it cultivated the blood refining method, it would become sleepy. This was the effect of the Universal Blood Refining Method taking effect through the contract mark.
It turned Little Dou into a transfer vessel that absorbed and refined Spiritual Power.
Thump, thump!
Duke's heart gave off a tremendous pounding sound. Anyone standing nearby could hear it. This was the rumbling of the blood sea.
Every time his heart pumped out blood mixed with battle qi, a powerful rumbling of the blood sea rang out.
His blood vessels carried Spiritual Power from his entire body to his heart. After passing through the blood sea and being transformed into battle qi, it was pumped out from the heart and flowed into his meridians, traveling along them to every limb and bone.
If the spirit sea could compress Spiritual Power into liquid form, then the blood sea could only compress Spiritual Power into gaseous form.
