What made the two universes different? The alien universe has a higher concentration of energy. That made our people suffer when going there, but not the other way around.
So this pillar was doing what my universe lacked, condensing the energy into such deadly concentration, enough to affect and weaken them while giving me a boost.
But seeing them getting this weakened made me think about a way to help them.
"Thundering Might!"
I used my pillar again, and this time the effect was weirdly different.
The pillar of light that enveloped my chariot seemed to be aggressive against any other form of energy, as if it took it as a challenge to its authority or something.
So in front of my eyes, the two forces kept fighting back and forth, until my pillar formed a small world for the first time ever.
It was a bubble of almost half a mile radius with my chariot in the centre. But when it appeared, all the negative effects coming from this pillar vanished.
