From my high spot I could see the ground starting to dye in fierce blackness as if a wave was slowly forming down there.
The more monsters killed by my boys, the wider this effect expanded.
I feared that this world might have undesired changes. But after a few minutes, and when the centre of that blackness started to turn lavish green again, I could only heave a sigh of relief.
The intensity of the green colour that appeared was much denser and a lot livelier than other parts in this world had.
"So… The other items will expand the area of this world, while this artefact will raise the grade of death energy here… Interesting…"
During the time I spent thinking about a solution for this dilemma I revised the description of my pocket world many times in my mind.
And from it, I got to know that the death energy here would give birth to many things, plants, trees, and other forms of life, even ores.
