day and night I kept cultivating continuously that I almost got sick of it, my cultivation soared up thanks to my talent and my resources and by resources I mean the pretty rule orbs I got from the lake, I already used five orbs on my cultivation directly apprehending, ice, space, wood, light, and spirit rules and to a certain degree, I could control them like the back of my hand. I also found that cultivating inside the coffin clears the mind and cultivates the soul, I doubt that the coffin was made for the purposes of reviving the death.
my assumption is not baseless, I can lay there for a day, and my soul quality doubles, the artifact is a coffin, just with these two facts who won't figure it out ?!
