A holy body for a hundred eons, three levels for one day…refined to one hundred thousand levels!

The Heavenly Reaper Technique, if you use it, you will be backlashed by the destiny… Let me first calculate the color of the saint’s clothes tomorrow.

To break the delusion, you need to look directly at the indescribable things…

Birth and death, being scoured by the secluded capital Huangquan every day…
