Comments of chapter undefined of A World of Reincarnators

Thanks for the chapter! How come Mitsuna feels so much weaker when compared to when she was a slime, did merging souls not give her all the same abilities back? Before her reincarnation it was said (if I remember right) that she invented a new motor with double the efficiency as a show of her intelligence. Ik she was way too op last time really quick which made writing obstacles to overcome hard, but now Mitsuna's progression feels sorta nerfed when she has the combination between her first, second, and third life.
