After Duke returned, he took out the Shadow Insect Bag and infused it with some Magic Power.
The Shadow Insect Bag itself does not store Shadow Insects; essentially, it is merely a summoning medium. Infusing it with Magic Power allows you to summon some Shadow Insects.
The more Magic Power expended, the more Shadow Insects can be summoned.
Five Shadow Insects crawled out of the Shadow Insect Bag. Since they hadn't yet received Duke's command, they were merely fluttering around him.
The Shadow Insects were only as big as a pinky fingertip, very small in size, and entirely black.
Duke could sense the state and location of each Shadow Insect through his own Spiritual Power, and could also receive some simple feedback from them.
He immediately realized that Shadow Insects could also be used for reconnaissance and alert purposes.
Although the information feedback from Shadow Insects was simple, they could still report whether there were any living creatures around and how many.
