Isn’t it just killing an SS1 mutated gray rat...

wrong.

its not right.

By killing an SS1-level mutant beast, I can get 100 combat merit points.

However, now, my battle merit points have only changed from 65909 to 65910.

Increased by 1 point.

What about the remaining 99 points?

Before killing this SS1-level mutant beast, the madness column was 1 (100), but now it has become 100 (100), increasing the madness value by 99 points.

hey-hey.

Does this mean...

I'll go for it.

The so-called madness value is the battle merit point.

Moreover, the battle merit points gained in the battle will be replenished first in the madness column, and then the battle merit points column will be replenished.

That's right.

This is the most reasonable explanation at present.

Ha ha.
