The six Milleras who fell down in front did not have Qin Lun's detection ability, and they all fell into a bunch of them at this time. Fortunately, these people were very strong, and several elf rangers were not inferior to professional apostles. They used various means to slow down the falling speed on the way, but they were not seriously injured at this time.

"What is this?" Just as Qin Lun and Ilistin were embarrassed, Milleras's lost voice came from next to him.

Milleras' shouts woke everyone up. Everyone stood up regardless of the pain on their bodies and looked at the surrounding environment. They just fell down, and it seemed that a thick layer of dust was stirred up in the pit. Now everyone's vision was still a little blurred, and a choking and stale breath penetrated through their noses, making everyone feel itchy in their throats.

The silver clock in Qin Lun's eyes quietly disappeared because he found that the pit that should be the belly of the mountain was full of soft and elegant misty light, which was not like the dark tunnel before.

After the dust stirred up dissipated a little, everyone looked at the surrounding environment and showed a hint of unconcealed surprise on their faces. The pit in the abdomen of the mountain is extremely wide, about fifty meters high. Although the edges cannot be seen clearly due to the dim light, after a rough observation, it can still be estimated that this place has at least tens of thousands of square meters of space.

At this time, everyone had already seen clearly where the light source in the pit came from. It was a luminous crystal wall about thirty meters above the ground on the east side of the pit.

"It's the light transmitted from the outside world, it's an ice wall!" Longer, who had excellent observation skills, first realized it and exclaimed in surprise.

"The more than ten stone pillars here do not seem to be formed naturally, they seem to be an artificial building!" an elf ranger murmured.

Everyone looked in that direction and soon understood the meaning of his words. In the center of the pit, there were twelve stone pillars about twenty meters high in the middle of the pit.

The bases of these stone pillars are very thick, and each one needs more than a dozen adults to hold them together. It is a bit inaccurate to say that they are stone pillars, because these stone pillars do not connect to the top of the pit. Compared with the length, width and height, they look more like twelve large, thick and short stone piers.

After careful observation, everyone's faces were even more surprising. Several flat and spacious channels were penetrated under these stone piers, similar to canals, but compared to canals, the bottom of the canals appears lighter.

In addition, several huge stone ropes were connected to the upper ends of the stone piers. Looking along the stone ropes, everyone was surprised to find that there was not only one tunnel they had fallen into this mountain cave before.

There are also dozens of huge drum-shaped tunnels above and above the stone walls and above. At first glance, it looks like a giant honeycomb. Most of the stone ropes connected to the stone piers are connected to these tunnels.

It seems that Qin Lun and Stark had previously judged that the tunnel was the nest of some kind of giant snake and insect, and there were some deviations. These tunnels were originally connected to the mountain-bellied stone cave below, but were later occupied by some soft creature.

"Pentamental Star Crystal Mirror!" Qin Lun looked at everything in front of him, and his heart moved. A huge crystal mirror appeared at his feet. The subsequent elemental critical strike made him jump high, and he stood at the edge of a tunnel connecting the stone rope after a few ups and downs.

"These things... don't seem to be stone pillars!" Milleras, who stood under a stone pier, suddenly widened his eyes and shouted in surprise, "This is a furnace! These are giant furnaces!"

Everyone was startled and went up to watch. The outline of the furnace door and the blocked vent were vaguely visible on the lower part of the gray stone pier.

At the same time, everyone thought of the flat and spacious channels at the bottom of the stone pier. Those were indeed not water channels, but channels for furnace water. Perhaps some of them were the notches where the furnace discharged the molten iron.

At this time, Qin Lun, who had been swept up the high altitude tunnel, also discovered something. He glanced at a square object at the entrance of the tunnel, and gently scraped the stone rope under his feet with a dagger, and soon saw the black and brown rust inside the stone rope.

These stone ropes are not real stones, but iron ropes covered with stone chips on the surface. When we contacted the square object in the tunnel, everyone understood that the thing should be the aerial cable car that provides ore to the twelve furnaces.

"Did we really find the ancient times, Sannata Dwarf's furnace castle?" An incredible thought arose in everyone's mind, but they vaguely felt it was taken for granted.

"Two Princes, we, we..." An elf ranger beside Millaras looked excited and looked at Qin Lun and Millaras with some expectations.

"Even if you want to explore, you have to wait for all the friends on the ground to come down. If you leave now, Miss Kelly will not see you later, and you will be furious!" Qin Lun reminded with a smile, "What's more, there should be other dangers here. It may have become a nest of some giant creatures. Be careful."

"Then... well, let's wait for them first!" Thinking of Kelly's fierceness, not to mention the few elf rangers, even Milleras couldn't help but shrink his neck.

It's strange to say that this Japanese elf prince can be regarded as a noble and cold genius in terms of mind and strength. He just gets impotence when he meets Kelly and is always eaten by her. Those who don't know the relationship between the two think that this is bronchitis of love. In fact, only those around Milleras know that this is the rhythm of natural enemies.

"Apostle No. 70053, you have discovered the unknown dwarf castle in the Alamir Mountains, please explore more here. The increased world exploration here will give you twice the extra reward."

Looking at the prompt message on the death list, Qin Lun's face became even more smiling. Although he refused Milleras and the others' proposal to go deeper into the castle, everyone still couldn't suppress their curiosity and began to explore the furnace area of ​​this dwarf castle.

"Feral~~" Looking at the scattered companions, Ilistin couldn't help but pull Qin Lun's sleeves and looked at Qin Lun resentfully.

"What will be time to explore. Your radius is broken. If you don't want your arm to grow into deformities, be quieter!" Qin Lun replied in anger, took out a box of green ointment from his arms and applied it to the elf druid's arm.

This box of ointments is also one of the adventure items prepared by Adeline and Menon for the two. It is a trauma ointment with the best effect as compared to the best intermittent ointment of moonlight. Priest Menon, who believes in the goddess of life, is enough to mix the best recovery items if there is materials.

"Two princes, come here to have a look!" After Qin Lun handled Ilistin almost the same, several elf rangers who had walked almost far away suddenly shouted excitedly.

"Be gentle, we are not on an outing!" Qin Lun stopped him with laughter and cry.

"Forget it, Philal, don't blame them, I can't even help it!" Milleras smiled and waved his hand, "This is too depressing for a while, and I always wander between life and death. Maybe this time it may be that I can't get out of here. Let's face death with a smile!"

"Hehe, Milleras, I feel you are much more cheerful!" Qin Lun raised his eyebrows and said in surprise.

After a chat with him two days ago, the Japanese elf prince seemed to have put aside his worries and began to devote himself to this journey of uncertainty in life and death like a real adventurer, treating it as a rare adventure.

"Look!" Milleras didn't care about Qin Lun's resentment at all. He stood in front of a giant stone tablet found by the Elf Ranger, pointed at it excitedly and said, "I know where this place is, Iron Star Fort, Iron Star Fort of the Augran Dwarf Kingdom! Firal, we found an ancient legend!"

This monument is in front of a last furnace, and the text engraved on it is blurred. However, under the cleaning of Milleras and several other elf rangers, you can still see the largest ancient texts on the upper end.

These words have two names in the translation of the Broken Starry Sky. One is called "The Wall of Alamir" and the other is "Iron and Stone Star". In the records of the Elf, this is part of the dwarf Sannata Empire, the "Iron and Star Fortress" of the Kingdom of Aograng, which was established more than 6,500 years ago.

"Apostle No. 70053, you found the legendary Ogrand's Iron Star Castle, and the world's exploration level increased by 0.002%. If you can find other relevant written records in the castle, the world's exploration level will continue to increase."

"This is just the furnace area of ​​the castle. I really want to go to other places in the castle right away. Why haven't Miss Kelly and the others come down yet?" Milleras finally couldn't help complaining.

Qin Lun laughed in his heart. Those who were rescued dared to blame others for saving people. If Kelly heard Milleras’ complaint, the Japanese Elf Prince would inevitably be beaten up.

Qin Lun looked at the huge stone tablet in front of him, and a trace of excitement flashed in his eyes. His curiosity was actually no less than that of Millaras and other elves. However, his curiosity was different from Millaras and others. The plot elves were just excited about finding the Iron Star Castle, and were curious about the history and records of this castle.

In addition to these, Qin Lun was also very interested in everything else in this Iron Star Fort. For example: the twelve giant furnaces in front of him!

Qin Lun slowly circled around a furnace, and his left eye pupil was flashing with a black and red target. He used his perspective ability to explore the interior of the furnace.

After thousands of years of precipitation, these furnaces have completely turned into fossils, and the furnace used to smelter ore has long been blocked. The internal structure can only be distinguished by the distinction between different stone quality.

What surprised Qin Lun was that the bottom of these furnaces was actually a loose limestone structure, forming a unique pipeline that reached the depths of the underground in the field of view of the left eye.

After observing several furnaces in succession, Qin Lun finally confirmed the structure of the furnace. Although limited to perception, he could only see more than 100 meters below the furnace, but suddenly he felt that the pipes at the bottom of these furnaces were probably going to extend to the depths of the entire Alamir Mountains.

Did the Alamir Mountains once be an active volcano? The dwarves of Sannata actually dared to build a castle in the crater and directly use underground lava forged steel!
