"I compressed the lightning power repeatedly by coiling them again and again. And I only managed to make seven because it's still hard for me to do it.
I have to control such a high level of energy and continue compressing while controlling them like thread and making sure that they don't get entangled while being compressed.
I had to control a lot of lightning threads to make sure that they are powerful enough to serve their purpose.
I also have to make sure that they won't loosen immediately and will hold as long as they are trapped in the metal shell that I had made.
I tested many times to see how much power I could trap using the metals that have the highest resistivity that I have.
But even though it could certainly hold the lightning that I have put inside, it's still very fragile, so it's very easy for the lightning inside to be released and cause an explosion.
