Sacrifice me in your ritual

I am pleased for my blood to spill. Do you think Satan will reward you greatly? Will he be pleased to have me as a sacrifice? Soon you shall know. Offer me to the underworld and see if you get riches, power, and everything else you have always dreamed of or if your life will remain exactly the same. I will not try to save myself but instead I will feel the ceremonial dagger plunging into my skin, waiting to see if the devil appears during my last moments as my life drains away.
