"Who, who. First raise the shield to protect the body, carefully observe the surroundings, make sure that there are no creatures around, in the dark environment, how can you not find the source of the sound, Mobuck complained loudly, "Damn, you have the ability to come out, what kind of ability is it to hide." ”

"Shut up. The cold Mia glared at him fiercely, "The person who spoke is not here, haven't you seen sound magic?"

"Huh, it's sound magic. "Mobuck scratched his head, the great dwarves didn't care about something as mysterious as magic, well, certainly disdain.

"Of course not, it's just something like that, in other ways. And the pronunciation is repeated back and forth, and a few sentences have been looping, which can only be a message. Shure, have you woken up?"

"I don't sleep while walking, of course I'm awake all the time, but I just want to maintain my magic and not be distracted, I listen to what you say. The surrounding shields of light had disappeared at some point, and the floating sacred texts had fallen back into his palms, and Shur finally had time to observe everything around him.

It can be said that here is another miniature version of the underground city, the same hemispherical caves, the same internal buildings, only here is only one floor, and the scope is much smaller.

"No, the top is not hard glass, both the top of the head and the feet are sealed with metal, and this is certainly one of the most important institutions. Shul pointed to the top of his head, "Come to think of it, the daily activities of this underground city are all supported by energy, and it is inevitable that it will be well defended." Mia, the location of the energy supply equipment. ”

"Of the eight buildings, the third from the left has a high energy response, and the problem is that the end of the backup energy pipeline is the fourth building. ”

The same hemispherical building, the same curved outer wall, but it always looks stronger.

"Transit node?"

"I'm talking about the 'most' end. ”

"Okay. Shuer nodded, "There's no need to guess, just go over and take a look." Ladies and gentlemen, the alert level is lowered, and the first level of alert is sufficient. ”

"Boss, no problem. "Although the alert level has been lowered, he has been burned once, and he has witnessed the whole process of Shuer's sneak attack just now, Macageren does not dare to take it lightly anymore, and he will never leave the team at all times.

"It's closed, there's no gap, obviously it's chaotic outside, but it's not affected here, it's still normal, so it's safe. Well, there's a high-energy reaction here, and the temperature is going up. ”

Indeed, although the houses were made of stone and metal and the walls were thick, you could still feel a hot breath coming through the walls. If this is really where the main energy supply equipment is located, it is estimated that this level of energy overflow alone could blow up the city at any time.

"Mia, Miriday, protect yourselves. ”

Although there is no need to worry too much about the existence of strange enemies now, the closer you get to the house, the more violent the energy you sense, and Shur has to be extra careful, lest any action is wrong and detonate the scorching energy inside.

"Mobuck, guard the entrance, Moria, perimeter guard, Miriday, support with your back against the wall, you three stay outside. ”

The high safety factor is also relatively speaking, and it is necessary to guard against being cut off at all times.

"Others, come in with me, Macajalen. ”

"The door has been opened, and I am professional. ”

"What is the structure of this kind of door, which is physically locked?"

"No, the kind where the mechanical control shrinks to the sides, without the lock, is controlled from somewhere else. I used my fighting spirit to directly control the ...... inside through the wall."

"Well, I don't need to go into details. Shul interrupted the halfling's gleeful introduction, "Mia, be ready to suppress the energy rampage inside. ”

"The strength is insufficient, the difficulty is too great, and the possibility is not high. ”

"I know, I'll help. ”

"That's not a big deal, come on, I'm ready. ”

"Huh", this time, the metal door slid silently into the walls on both sides, without making a harsh noise at all, it seems that the high temperature minimizes the moisture in the environment, allowing the metal to temporarily escape the fate of rust.

"Tsk, this structure, it's really ......"

Inside the door is a second metal wall, with a radius of two meters from the outer layer, leaving a corridor between the two walls. In desperation, I walked along the cloister until I reached the opposite side of the entrance, and through the second door, I could see the ...... The third metal wall.

"These frogmen really know how to design, are they going to build a labyrinth?" After another big circle, in front of the third gate, the halfling seemed to be possessed by Mobuck, and couldn't help but whisper, "If it opens up and it's another wall, it will be interesting." ”

"Probably not, their design seems to be guarding against something, certainly not against explosions, insulating the temperature? Shure noticed that Macajeren was looking at him with an inquiring look, and nodded, "No matter what you are guarding against, the three metal walls are almost the same, let's see what they use as energy." ”

As soon as the door opened, a bright light shot out, and the strong light was unobscured, and the eyes of the stinging people were painful. With the strong light rushing out of the door, there was also an astonishing high temperature, even standing at the door, the skin on his face was still hot, and even the hair on his sideburns was slightly curled.

"It's so bright. Saf behind Shur was the last to react, even with glasses, her vision was still very insensitive, the girl rubbed her eyes, trying to see the scene behind the door, but in the end she failed, "Shuer, what is it, grunt?"

"Hear me? It's magma. Seeing everything in front of him, even Shuer froze for a few seconds, and the corners of his mouth twitched and said, "An underground crater, a natural magma pool. These people are really imaginative, and they actually use geothermal energy directly. ”

Indeed, this is where the frog people come from.

The magma pool, which is hundreds of meters in diameter, exudes a terrifying high temperature, but fortunately it is the physique of the professionals, if it is replaced by the aboriginal frog people, I am afraid that it will have been baked by the heat wave long ago.

Around the magma pool, the frogs built a large number of mechanical devices, and although they do not know their exact function, they must have used them to convert geothermal energy into usable energy.

"I know the purpose of the first two buildings. Mia seemed to be extremely relaxed, the elemental mage was always accompanied by the furious energy, and this level of heat did not make her feel uncomfortable.

"Well, the site for replacing special equipment such as thermal insulation clothing, and the other should be a water storage station, which is dedicated to supplying water to the equipment here to cool down. Shul nodded, "Let's go, let's get out." ”

"Well, let's get out. Mia nodded in agreement.

"What? is leaving?" said Macajelen in surprise, "Aren't we going to restore the energy supply?

"You're a mechanic yourself, do you think they might still work? Equipment that works in high temperatures loses cooling water, which means that it is already dead, and it is a waste of time to re-check. Moreover, even if there are really one or two that can be saved, I'm afraid it will be seriously damaged, this type of energy conversion equipment Pavatiga is rare, you can solve small problems, this kind of big problem is not much different from making a new one, will you fix it?"

"Well, it won't. The halfling had to admit that what Shuer said made sense, he had made a hasty observation just now, all the equipment had been shut down, and most of them had traces of melting from the appearance, and there was really no room for recovery, "Then what should I do?"

"Sasa, can you break the wall? Forget it, don't try, go back the way you came. "Two layers of metal sandwiched between a layer of insulating rock, and a wall at least a meter thick, not unbreakable, but meaningless.

"Don't worry, there's hope, don't forget that there's a building next to it, and that's where the energy pipeline ends. Mia, here'......"

"Theoretically, the energy here is also going to be delivered over there, which is the end of the pipeline. However, there is no energy output here, so there is no way to prove it. ”

Although Shul said that there was still hope, even he himself was not very optimistic about the so-called hope.

Geothermal energy is an almost inexhaustible source of energy, and since it can be converted, there is no need to make other energy supply equipment, and the possibility of restoring energy to the city is already very small.

However, not letting go of every one of the goals of the shadow chasers, even if there is only one percent hope, try it, and if you really can't do it, then you have to go to great lengths to explore the city in the dark.

However, when the fourth building is seen in the dark, it is not hope, but strange. In terms of shape, it is no different from other buildings, at most it is larger, but unlike the metallic appearance of other buildings, this building has a rough appearance, a piece of dust, and has no beauty at all, like a shoddy inferior product.

Tentatively touching the walls, it seems that roughness is not only a visual effect, but also has a feeling of non-smoothness, and the whole building is like this, obviously intentional.

"It's kind of weird. Shure took a few steps around the wall, frowned and thought, "Mobuck, what's that metal out there?"

"Inconel, this thing can also be made on our side, but the raw material is not very common. "Mineral experts often only need a few taps to determine the approximate composition of a metal.

"And what about this?" Shure patted the gray wall behind him, "it must be some other metal." ”

"This one is a bit strange, it's a lead alloy. Mobuck touched his beard and teased in his tone, "This alloy has a very low hardness, I can smash a hole with a punch, I really don't know why they use it to build a house, it's just ......"

"Wait, you said it's a lead alloy?" Shure suddenly clenched his fists, his eyes shining, "Are you sure? You'd better make sure again." ”

As for the conclusion of his teammates, Shuer rarely asks for repeated confirmation as he does now, and only the most important link will be as cautious as he is now.

"Uh, I'm sure. "Mobuck threw two punches directly into the wall this time, and indeed as he said, there were two more shallow depressions in the wall.

"Heh, if it's a lead alloy...... "Shure licked his lips and smiled brightly, "You've probably heard of Cursed Metal." ”

"Hell, my gosh. ”
