"Spiritualization comes with many benefits apart from the increase in lifespan." Sheele said as we went back to our room.
I received a couple of gazes from the others in the restaurant but most were of bewilderment with one exception.
A man who could only be classified as creepy looked, not at the old lady disguised as a teenager but the genuine kid land then looked at me with envy.
"Sai?" Sheele called me out of thinking about the thirty different ways to kill a man's heart without use of violence.
"I'm listening."
"Good. First benefit is the increase in mana capacity and output. If your output before spiritualization is 10, then it becomes 100 after. Your mana consumption per spell is also lowered to the point that unless a Supreme Art or World End magic is used, it is near impossible to run out of mana." We opened the door to our room and was confronted with a sight straight out of hell.
