Changes in the Azure City

From MC's perspective:

The following day,

Sitting cross-legged in the training room. I took out the Class-5 Monster core and held it in my palm. This one monster core was enough for me to sustain a few hours of cultivation.

Then I closed my eyes and started to run the blood element method. As I recite the words, the blood rune in my mind starts to flicker. 

The next moment, I felt suction in both of my palms and began to absorb the monster's core energies. The energies of the Class-5 Monster were more violent than the Class-4 Monster.

So I began to guide the energy slowly. As the energy flows through my veins. I felt the violent nature. But that was for a moment. 

As I circulated the blood, a red light appeared above the bloodstream. Then they start to absorb the monster's core energies and then convert them into the mysterious white energies.
