The trade store closed.
Ming climbed onto the roof and placed the arrow tower there. The arrow tower covered an area of 2 square meters and was two meters high. The tip of the tower was conical, very similar to the dome of a church. Above the dome was a four-clawed metal buckle, presumably for holding the spirit stone. Below the dome was a large crossbow, and further down was the base of the arrow tower.
He placed a spirit stone in the metal claw buckle on top of the tower. Click! The claw buckle tightly grabbed the spirit stone, and light blue glows spread from the spirit stone to the entire arrow tower. Then, the arrow tower slightly rotated, and the crossbow automatically loaded, like a soldier guarding a territory.
Not bad!
