Herag didn't quite understand how these demons recognized identity.
For instance, this two-headed wolf, which was seeing the three of them for the first time, could still identify them as allies.
Herag could only guess that the identity information of the three of them was recorded in the witch array of Base 27.
And the interior of these shadow altars is likely connected to the witch array of Base 27, so the summoned demons could distinguish friend from foe.
Herag estimated that with his magic power, he could probably summon over a hundred shadow demons in a day.
He turned to David and Reese: "You both try on your own and calculate how many you can summon in a day."
"I'll give it a try." David walked to the altar and, like Herag, began channeling magic power to summon shadow demons.
A few minutes later, an eight-legged spider crawled down from the altar.
Reese screamed and instinctively hugged Herag.
Herag felt a bit restless inside.
