Slave of sorceress

You died and got transported to another world. You got no titles, no powers, no special items, no artifacts, no weapons, not even a helpful system. No, you happened to be transported just in perfect moment as certain elf sorceress was using a slave summoning ritual. It pulled your soul towards her and somehow you became a slave. Your new life isn't great adventure like in isekai stories. Instead, it's a new life of servitude.
