In the circular room, Rand found a separate downward passage that connected to the magic furnace room of this ruin, the size of the magic furnace here was similar to iron ore, but in the magic furnace room, Rand saw a large number of blue crystals, these crystals are the kind that drive the goblin cannon, but the quality of the crystals in the magic furnace room is much stronger than the ones in the hands of the goblins.

"No wonder those goblins can fire guns at any cost, and co-authoring is a mine to build casually?" Rand looked at the crystal in front of him and muttered quietly. "So there are not necessarily leylines in the ground here, but it is likely to be this kind of mineral vein, which can achieve a similar effect to the leylines through crystal storage magic?"

After finding the magic furnace, Rand has a bottom in his heart, and in the worst case, he can also return to Night Qi City through the existing portal core kit.

"Rand, there seem to be some patterns on this room, come and take a look!" Agni found a small space near the furnace room, the area of the room was very similar to the emergency communication room he had seen before, and there were even large circles on the walls, but the circles here were more similar to the goblin cannons that Rand had seen, and it was in the style of circuit diagrams.

Around the room, you can see goblin paintings, delicately printed on metal plates, neatly arranged on the walls.

"Hey, that's interesting," Rand said with a smile, "It's a magic furnace here, and instead of building a portal or a control room, it's actually an art exhibition?" ”

Rand pulled out the Sword of the Demon Net, wanting to find out if there was a hidden mechanism behind these metal plates, but he didn't expect that as soon as the blade touched one of the plates, there was an immediate movement on the ground, and a magic circle suddenly lit up, and the light covered the entire room.

Suddenly, Rand and Agni seemed to be in the starry sky, the earth under their feet continued to shrink, and the perspective gradually changed from a sinkhole around the Hindukr Basin to the entire basin, then to the Eastern Continent, to the entire planet, and then to the cosmic sea of stars.

Not only did they see the starry sky, but Rand and Agni also heard a message at the same time, which was obviously in the language of goblins, but both Rand and Agni could understand the meaning.

The general content of the information Rand also understood that it was the space-time location of the planet they were on, from the location of the planet in the entire galaxy to the geographical location of this cave, which was very detailed, and after about 2 minutes, the light of the circle disappeared, and Rand and Agni returned to the cave.

Agni liked this novel audio-visual experience very much, and exclaimed, "Rand, this is amazing!" ”

"yes, it seems that the goblins have a very macro understanding of our world," Rand nodded, stroking the metal plate on the wall again, "So these metal plates are a special information storage medium?" Need a specific circle to play? ”

After understanding the principle of the metal plate, Rand touched the second plate with the blade of his sword again, which had a portrait of a goblin on it.

As the light of the circle reappeared, Rand and Agni returned to the rotunda upstairs, which, unlike the dilapidated scene of today, had once been the temple of a goblin demigod, and the introduction of its owner changed with the picture:

"Mogrec, goblin mage demigod, the greatest space walker in history, and the master of Mogrub Castle, who opened up the star mines and gave the entire empire an ample supply of gold."

In the picture, Moge Fort, that is, when this ruin was once used, the so-called sinkhole was more like a mining facility, and now it is a wide open space, and there were originally complex magic circles on it.

Not only the open space, but also the surrounding mountain walls were full of magic circles, and as Mogrok held his wand in the main hall and released his magic, a super spatial rift with a diameter of no less than a kilometer appeared above the sinkhole.

Then an asteroid squeezed out of the chasm, and in the process of falling, it was shattered by layers of magic circles on the ground, and finally became rubble of various sizes when it landed.

"Woon" Rand looked at the effect, and became illiterate for a while, he finally knew what the goblins meant by interstellar mining, and if he could play like this, the goblins would definitely not look down on the metal mines underground.

The precious metal content of that metal asteroid is comparable to that of mining for hundreds of years.

As the picture ended, Rand and Agni did not hesitate, and directly looked at the content of the next painting, and the metal paintings behind them left technical information, such as the location, function, size, and usefulness of the magic circles on the four magic furnaces in the entire Moge Castle, as well as how to coordinate and link the magic furnaces.

"There are actually 4 magic furnaces in here?" Agni saw the picture and suddenly came to his senses, "Then we should move all these magic furnaces back?" ”

Rand shook his head very seriously: "There used to be 4 of them, but now it is not necessarily, this room is the control room of the entire magic furnace, I didn't notice the 3 magic furnaces from the magic net, it is possible that they have been stopped by His Majesty Willy, and it is certain that only this one can move." ”

"The goblin civilization actually perished like this......" After actually feeling the power of the goblin civilization, Agni was also saddened by the depravity of this species, "I don't know what they did?" ”

"But we at least know why there are so many gold coins upstairs, and this is a mint!"

"So what now? Go back and get some people over first? Or do you want to report this to the legends of Red Dragon Rock? ”

"Not yet, we still have a little thing we haven't seen!" Rand shook his head, he still hadn't found the magic cannon, nor the goblin who repaired it.

"This is a goblin demigod mage's castle, with a mage's magic furnace, magic books, and meditation rooms, but it's clear that there's a place to produce or at least maintain those cannons, otherwise those goblins wouldn't have survived until now!"

"Then it's impossible to be on these floors, just because of the size of those goblins, it's impossible to run up and down with a particularly heavy cannon," Agni added, as a horse, very concerned about the transportation of goods, "Let's go downstairs and look for it!" ”

Rand returned to the hallway without a circle with the flames, and after checking it anew, he finally noticed the space behind the wall near the gate of the ruins.

Only after approaching the Sword of the Demon Net, he could barely feel a circle of door-shaped lines on the rock wall, but what made Rand more curious than the gate was that from the magic net, he could also feel that behind the wall, there were two beings the height of demon supporters, who were standing motionless.
