The Journey of Survival in the Apocalypse After Transforming into a Beautiful Girl

I'm not a battery! Hmph!

I couldn't make an electromagnetic cannon right now. It needed a guide rail, as well as something that could withstand the recoil when the cannon fired.

A coil gun, though, was much simpler.

For the past few days, whenever I had a spare moment, I'd been testing the current and voltage.

It was Xiao San's idea: use a high-voltage tester to measure the voltage in my body.

Voltage was generally proportional to current. To use water as an analogy, current was the river, while voltage was the atmospheric pressure and gravity pulling the current down from a higher place to a lower one.

The higher the voltage, the greater the current.

Put simply, the greater the pressure, the faster the water flowed.

No matter how great the current was, without voltage it was just stagnant water. It couldn't flow, so it couldn't hurt anyone.

So the main thing to measure was voltage.

And wouldn't you know it, my voltage was exactly 220V.

That was my maximum output.

Yeah... So now I was in charge of charging those sisters' MP3 players... in charge... of it.

Damn it! My ability wasn't supposed to turn me into a battery! And I wasn't a universal charger, either!

But it was really hard to refuse when those two sisters looked at me like that. They were a pair of fourteen- or fifteen-year-old girls, and they had that sort of "three years of profit, no loss even if you get the death penalty" look.

I really couldn't say no.

So I had to touch their two charging plugs with my fingers and charge their MP3 players.

But maybe because I'd been putting out so much power for so long, the electricity my body produced had started to fluctuate. Of course, I
