[Day 130]
It has been four days since I began the soul treatment with Benladann. These days I've made her consume souls of monsters every day, by the hundreds.
Eating souls was something she wasn't capable of doing naturally, I had thought about making Soul Puree and then add it into her soul manually before, but now that she got the ability to eat souls thanks to her mother's gift, things were faster than I had expected.
After four days of eating almost a thousand souls, her Soul Mass and Soul Density had reached a good enough amount to cover the entire area of her soul after I compacted it a bit using my Soul Hands, to squeeze her soul a bit.
Using this Soul Mass, I used my newly acquired Death Magic Spell "Soul Membrane" which could be used when connecting my soul with another and it let me create a soul membrane using the target's Soul Mass. It was a very specific spell.
