From MC's perspective:
"What the fu#k?" I uttered in surprise. As I had guessed before, the malicious aura is useful. The blood element method is absorbing the malicious aura around me.
Then after taking a deep breath. I sat cross-legged on the ground and started to run the blood element method.
When I ran the blood element method. The bloody rune in my consciousness started to flicker. The next moment, a heavy malicious aura rushed towards me.
I calmed down my mind and began to absorb the aura slowly. I want to see what changes are going to take place inside my body.
But right after, the blood element inside my body got triggered. The hazy red light came out from the bloodstream and started to swallow the malicious energies.
Seeing that my eyes gleamed with a twinkle. But the next process is going to be painful. When I'm looking forward to energy conversion. I see a sudden change in the process.
