"Elf Arrow Tower?" Brand asked, "This sounds like a city defense facility invented by the Silver Elves. The top layer of the Elf Arrow Tower has three rooms that can accommodate archers, each room having eight shooting holes facing all directions. There are two types of Magic Arrays in the rooms, Frost and Flame, which can easily enchant the arrows for the archers—"
"The three floors under the Arrow Tower have a munitions room and a crossbow cannon room on one floor that can accommodate two Elf crossbow cannons, am I right?" he looked up and asked.
"Lord, you are amazing!" Monica couldn't help but widen her eyes and exclaimed in a sharp voice, "It's almost exactly so, but there's one thing that's not right. In fact, the Silver Elves' Elf Arrow Tower actually evolved from the Holy Spire of the Light Clan, and Valhalla's Arrow Tower is the same, with slight differences from the Silver Elves' version, but they still maintain a parallel relationship."
