What should I do? Could it be that I need to find a pair of rubber gloves for insulation? It seems like there are no such things in the Underworld.
Suddenly, I realized the root of the problem. In the beginning, when I didn't concentrate my spirit on the iron chains, no matter how I pulled, there was no response. Once I focused all my attention on the chains, an electric-like current would emerge with a forceful tug.
Sure enough, when I thought about something else and used strength in my hands, the electrical current did not appear again—it seemed that my strength alone couldn't break the chains.
Do I need to use that explosive power again? I just used it once before, but can I use it a second time? There were no side effects the first time, meaning I didn't feel drained. But what if I use it again—could that cause me to feel exhausted?
