Feng Qian Yan cautiously opened the box, and inside was a palm-sized compass-like thing. With the center of the compass as a dot, there is a circle of circular lines every centimeter, which divides the entire disc into six concentric rings, which are engraved with complex patterns. On the outermost side, near the edge, a circle of small squares was densely arranged, about a hundred, and each small square was engraved with a character that Feng Yanyan did not recognize. The font and style are very similar to the inscriptions in the aperture that appear when you advance and contract. Among them, more than a dozen small squares are dented.

"Compass?" Feng Qian muttered and stood up, handing the brocade box to Xiao Yuchen, "Great Refiner, can you take a look?"

"This is the formation compass. Xiao Yuchen stretched out his slender finger and pointed to the outermost small square with the words engraved on it and explained, "You see that these characters are an ancient script, and refiners and array mages have to learn this kind of script to engrave inscriptions. These lines are the formation diagrams that need to be drawn when arranging the formation. ”

"How do you use this thing? These lines look so messy, I remember that there are not so many words on the formation. ”

"The lines engraved on this plate can form ten formations, you see ...... like this," Xiao Yuchen said, gently pushing one of the rings with his fingers.

Feng Qianyan looked at it in surprise, but he didn't expect that it could be turned. And with the rotation of the ring, the aura that had originally gathered from all around suddenly disappeared.

After half a turn of the ring, Xiao Yuchen turned another ring a quarter of a turn, and his fingertips slid along the edge of the lines while explaining to the wind: "You see, starting from here, in this way, it has become a new formation." As he spoke, he selected a few small squares that were recessed, and clicked them one by one, and the small squares bounced back and returned to a position that was level with the plate. Then, I chose a few more small squares and pressed them. On the surface of the compass, a layer of golden light flashed on the selected patterns and inscriptions, and a small formation pattern appeared on the surface of the compass, and disappeared after a while. At the same time, an almost transparent protective shield opened around the two of them.

"What kind of formation is this?"

"Intermediate protective array. The previous one was an Intermediate Spirit Gathering Array. Xiao Yuchen turned the lines on the compass at will, and the protective shield disappeared instantly.

"Is this closed?" Feng Tianyan blinked, "This is much more convenient than your current formation!, but doesn't the formation have to be driven by spirit stones? This compass doesn't look like it!"

"Look at the back. ”

"Oh. Feng Tianyan stretched out his little hand and took the compass out of the brocade box. At the moment when the compass left the brocade box, both of them stared at each other, and saw a folded, patterned triangular rhino animal skin lying quietly at the bottom of the box. Feng Qianyan and Xiao Yuchen glanced at each other: Could it be a map fragment?

"Just open it and see. Xiao Yuchen took the compass and brocade box in Feng Qianyan's hand.

Feng Qianyan took out the animal skin, unfolded it and looked at it, and it was indeed a map drawn on it. Slowly releasing a trace of spiritual power, after the white fluorescence on the map dissipated, the original pattern painted on it gradually faded, and a new map appeared in front of the two of them. Sure enough, it was one of the six fragments of that map.

Feng Tianyan was pleasantly surprised: "It's really lucky, I didn't expect us to get this map fragment by accident!"

Xiao Yuchen's doting eyes were smiling: "This is Yan Yan's chance, take it away." ”
