When the big explosion happened, the whole Prandal was almost blown apart, especially where the Sea of Abyss was now. It was the center of the explosion, and there were almost no traces of civilization left. Even in the territory of the Luminous Scale Nagas, there were almost no traces of civilization.
Only in remote areas, where the impact was relatively light, could there be some traces of prehistoric civilization.
This was why archeological teams always went to remote areas of the continent to look for ruins.
Grace was such a place.
Underneath the Alar Iron Mine, there was an ore refining center of the prehistoric civilization.
After the centipede-shaped mining robots collected iron ore and smelted it, they stored all the ore in the warehouse in their bodies. When the warehouse was full, they were transported to the ore refining center for secondary refining.
Tang En was very interested in this place, mainly because of their ore refining techniques. This was because Ellington's ore refining techniques were still very backward, and the current techniques were all learned from the dwarves. In addition, Tang En had magically modified the techniques from Earth based on his impressions. Although it sounded very advanced, in reality, this kind of technique that was casually created was definitely not comparable to the prehistoric Pygmy civilization that was trained in the field.
If they could learn the technology of refining ores from this ore refining center, the quality of Ellington's steel would definitely be greatly improved. Perhaps the performance of the universal alloy would also be improved. Therefore, the importance of this ruin suddenly increased a lot.
In addition, if they could find the alloy formula of the prehistoric civilization here, they would have one more usable material. If the performance was good enough, it might even be able to replace the universal alloy in some places.
Tang En followed Jindy and the others into the ruin. This time, Ding Ge was not stingy. He directly took out a lot of light crystals and installed them along the way, illuminating the dark ruin.
Due to its relatively sturdy structure, the ore refining center didn't collapse even after ten thousand years. It was only covered with a thick layer of soil, which should have been formed after the big explosion. The ore refining center should have been on the surface of the earth, but in the past ten thousand years, it had undergone some kind of geological changes. The uplifted soil turned into Mount Alar and buried the entire place underground.
The mercenaries in front were cleaning the dust here. Lockmar was obviously full of complaints about this job. He was now a dignified Guru-level Oracle, but now he was cleaning here. It was a waste of talent!
At this time, Aiguin came in handy. At Tang En's request, she used a clever spell to sweep all the thick dust aside and restore the original appearance of the ore refining center.
"Your fiancée is really amazing!"
Jindy exclaimed, "I've heard that most elves can cultivate both magic and martial arts, but this is the first time I've seen it."
Tang En smiled but did not say a word.
This was, in fact, a misunderstanding. Strictly speaking, the elves were not considered to be dual cultivators of magic and martial arts. Their magical abilities could be said to be innate, but if they didn't strengthen their learning, they could only cast some simple low-level spells.
But compared to humans, this was already very enviable.
After the ruins were cleaned up, Jindy and Dinger sent some people to continue exploring, while most of the people stayed to study the ore refining center.
But they were stumped at the first step because they could not enter.
The door of the ore refining center seemed to have triggered the emergency safety system during the explosion. The door was locked, and the internal energy system had been cut off. Facing the heavy metal door, the archaeologists were at their wits' end.
"So this is our time to show off!"
Dinger laughed, her voice sharp and ear-piercing. "You lepers always say that we are too violent, but in this case, how can you enter without using violence? If you can't even enter the door, don't talk about research and exploration! "
"As long as I'm still here! I'll never allow you to do anything! "
Jindy shouted excitedly, "This ruin is too precious! Your bombs could very well destroy this place! "
"Then tell us, how do we get in now?"
Ding Ge sneered. "I'm afraid this is a fully automated ore refining center controlled by automatons. There are no windows at all, only this door. Behind the wall is the mountain. Are you going to dig a passage behind it?"
Jindy was speechless, but he still strongly protested against Dinger's method.
In the end, Twain came forward to solve this problem. He asked Aegwynn to use the Stone to Mud spell to melt the solid mountain and find another entrance. Since this place was used to extract ores, it was impossible for there to be only one entrance. Even if it was to discard the waste, there would still need to be a separate exit.
As Tang En had expected, they found two exits at the back of the refining center. The larger one looked like it was used to transport ores, and the other one was probably used to discharge dregs.
Aiguin's ears twitched, and she suddenly said, "There's movement inside."
"It should be a patrol automaton," Jindy said calmly.
"We've encountered them in the ruins before, and they were very difficult to deal with. But now we have Lockmar and Lady Aemilia, so there shouldn't be any danger."
"Let us go in first to explore."
Lockmar took out his battle axe, eager to go.
"To be safe, I'll go too."
Although he was not worried that Aiguin would fall in love with someone else, he still did not want to leave Lockmar alone with Aiguin. He was so petty and unreasonable.
The three of them entered the ore refining center one after another. Aiguin cast Glimmer to illuminate the passage ahead. The dark passage was like an abyssal monster, and only their footsteps could be heard in the quiet passage.
Lockmar was alert and asked curiously, "It's so quiet. How did you hear something?"
Aiguin pointed at her ears. "I'm an elf."
"That's true. I've heard that elves have very sharp hearing …"
Lockmar stared at the dark passage ahead and said, "Compared to humans, elves can indeed be called the favored children of the gods."
Tang En shook his head. Favored children? Perhaps. But a sad race that was set as a 'firewall', shouldering a mission, and had completely lost their freedom and infinite possibilities in the future, could they be considered favored children?
"Kacha kacha …"
A series of crisp footsteps slowly approached them. Lockmar immediately stopped and stared at the passage ahead. A moment later, a few red lights appeared in the darkness.
They really came!
Soon, the patrol robots appeared in front of them. They were all 90 centimeters tall — the patrol robots developed by the gnomes and goblins. One could imagine what they would look like.
The robots were covered in a layer of dust. In the past ten thousand years, the paint on the surface had dried and peeled off, and the outer shells were dull. However, this was not the main point. The main point was that they were all holding a weapon that did not look good.
"Unknown target detected … Life signature scan complete … Signature database matching failed … Unknown creature confirmed … Authorization detection failed … Unauthorized target confirmed … Central system command not received … Executing expulsion procedure …"
After the patrol robots finished speaking, they all raised the guns in their hands. "Adjusted to freeze mode … Initiating expulsion …"
"Careful!"
As soon as Lockmar's voice fell, a fierce ray suddenly shot out, and the three of them were instantly repelled. The icy blue ray hit the ground where they had just been standing, and a thick layer of ice instantly appeared on the ground.
"These constructs actually know how to use magic!"
Lockmar broke out in cold sweat and became even more alert.
"Rather than magic, it's more like science."
Tang En complained, then gave Aiguin a look. "Control them, try not to damage them."
These patrol robots also had great research value. Their intelligence system, energy system, and weapon system were all very valuable, especially the guns in their hands. It was obvious that they were of the same system as the gnome's freezing ray that Clotho had installed on the Heaven Breaker. If they could bring them back for research, they would have new weapons to use.
Aiguin nodded and instantly rushed forward.
"Target not hit … Target threat level increased … Switching to destroy mode … Adjusted to high-energy pulse mode …"
As soon as he heard this, Tang En's scalp went numb. He saw that the front of the guns in their hands suddenly overflowed with a very strange blue light. At the same time, an extremely strong sense of danger suddenly surged in his heart. "Be careful —"
"Hum —"
There was a low buzzing sound, and almost at the same time, the blue high-energy ray had already arrived in front of Lockmar!
Lockmar only had time to forcibly twist his body to avoid the fatal blow. The high-energy ray slanted and pierced through his left shoulder. The blood aura armor did not do anything, and his entire shoulder was instantly vaporized!
"Ahhh —!!!"
Lockmar roared in pain. Tang En's expression changed slightly, and he immediately healed him. But just as the life force enveloped him, the attacks of the other patrol robots had already arrived!
Aiguin did not say a word and suddenly appeared in front of him, propping up layers of magic shields.
"Don't — Eh!?"
Tang En was surprised to find that the high-energy ray that had extremely strong penetrating power just now was actually partially blocked by the layers of magic shields!
No, to be precise, it was being weakened layer by layer!
After penetrating the layers of magic shields, the high-energy ray could not even hurt Aiguin's skin!
Why?!
