The day passed incredibly quickly. I found that night had fallen during the process, so I simply refrained from sleeping and continued. My body is not ordinary, and since I have mastered the first step of the Commandment, I can stay awake for about two months without any side effects, and approximately five months if I want to push my limits.
I was extremely careful in handling the potion, ensuring that everything was clean and sterilized multiple times. The last thing I wanted was to spoil the potion before giving it to Elara. Analyzing and reverse engineering it is difficult and complex and would take months to fully understand everything.
