My Sacrificial Summoning System Changed It All

"If power demands blood, then let it flow. I'll trade souls for strength, no matter the cost." Once the cherished son of a great noble family, Arthur’s life completely shatters when he is betrayed by his so-called brothers. Helpless, he watched as the person who meant everything to him, his mother, get brutally murdered before his very own yet, powerless eyes. Her last breaths haunted him, the image of her bare bruised body burned into his mind, fueling a rage he could never contain. But rage alone was useless. In a world ruled solely by strength, Arthur’s was taken from him. His mana core was shattered, his sight left half-blinded and his body crippled. The once-promising noble son was now nothing more than a broken shell. Just an ordinary being, No, by the world’s standard maybe he was even lower than those. He no longer wished to live, what value was there in living if he could only suffer in silence, forever chained by the injustice he’d endured? Just at the time, a whisper rang in his ear. Was this his chance? “What are you?” [Searching familiar terms so Host may better understand...] [Search complete!] [I am the Sacrificial Summoning System.] A system? “So, the gods haven’t forsaken me after all.” [The more souls are sacrificed, the stronger the summon will be.] "Or maybe it's devil," ******* Update Schedule: 1 Chapter a day.
