After Shadow successfully deployed his ability, the group quickly disposed of the others and let Shadow take care of their bodies inside his shadow realm.
The shadow realm was like his own personal pocket space that interconnected different shadows to each other, enabling Shadow to move freely between two points of space just by thinking about it.
It was quite a useful ability here, but extremely useful in space. Maybe if he could make use of the darkness present inside space, that would be something...
Shadow didn't kill the men they captured before, but he knocked them unconscious before throwing them inside his shadow realm.
After a while, the five men woke up, but they couldn't get out of his realm no matter what they did.
Lux wasn't the only one who improved; Shadow also managed to do it, especially after keeping busy a Holy Class for some time.
Despite almost being killed, Shadow managed to keep Malek busy for hours.
