As the days continued to pass, my preparation to refine the Source Energy Core was successfully finished.
Truthfully, I didn't need that much time, I could even go at it and refine it with my overwhelming Energy Control as is. Given that I managed to extract it with just that from its world, it's more than plausible. My preparation was only to ensure that nothing would be wasted.
The day after my conversation with the sly old man, I went to the various unearthed Disposal Sites, taking out some outdated technology from the bygone era.
One thing that I specifically looked for was the Energy Recycler and Condenser. They're nothing too fancy, just a simple tool most Sages use to potentially get the most out of Chaotic Energy and Level 3 Source Energy.
