A rocket engine using hydrogen.
“…”
Mikoto looked around.
The ocean water spread around her…no, the water molecules spread around her was made of oxygen and hydrogen. If she used electrolysis, she could retrieve the oxygen and hydrogen from the water.
She did not hesitate.
Bluish-white sparks flew from her bangs and a lightning spear was fired at the ocean surface.
But…
(It’s no good. I can break them apart, but I can’t turn it into fuel…!!)
Even if she could retrieve the oxygen and hydrogen, there was simply too little of it. To get anywhere, she needed to obtain a whole lot more hydrogen all at once.
The wreckage jerked below her feet.
She only had a few minutes before it completely sank.
(…No.)
Mikoto’s head suddenly shot up.
Something was odd.
