Lin Xuan finally began to believe in fate until now. If he hadn't met Nalan Rong, I'm afraid he would have been buried underground forever this time.

After entering the portal, Lin Xuan only felt his whole body tremble, and then appeared in a space of about ten square meters. With Lin Xuan's appearance, the surrounding flames lit up, and Lin Xuan also observed the surroundings excitedly.

In the room, there was nothing symbolic, and in front of Lin Xuan was a door two meters five high, and Lin Xuan walked out directly. In the memory of the Dwarf King, Lin Xuan knew. This is probably the heart of the Steel City.

The moment Lin Xuan stepped out, he was suddenly shrouded in darkness, and there was no light at all in this place three thousand meters underground. Directly summoned the Fire Qilin Martial Spirit, and Lin Xuan's surroundings instantly lit up. At this time, Lin Xuan was like a huge torch. But what was in front of him surprised Lin Xuan. The surrounding buildings reflected the cold light, and Lin Xuan came to the front of the building and found that all the buildings were actually made of metal. Lin Xuan heated the wall in front of him with a flame, and was pleasantly surprised to find that the melting point of this metal was obviously not something that ordinary flames could reach. At least Lin Xuan burned for five minutes, and the metal was only slightly red.

After inheriting the memory of the Dwarf King, Lin Xuan could be said to know this steel capital well. Although it is already known what it looks like here. But the feeling of being there is definitely something completely different. Lin Xuan understood that at this time, the entire Steel Capital was wrapped in a huge spatial enchantment. Lin Xuan hit a fireball above him, and he was surprised to find that it was definitely more than 100 meters here, which means that the city wall was at least 100 meters or more. Lin Xuan didn't say a word, and ran around the city.

But when he came to the city wall, Lin Xuan was very excited. Because his expectation was not wrong, the city wall of the Steel City was indeed more than 100 meters, and the thickness was no weaker than that of a first-class main city like Qinglong City. Lin Xuan came to the city wall excitedly, and was pleasantly surprised to find that there were countless huge devices on the city wall. Take, for example, the mechanical giant crossbow in front of you. Although Lin Xuan didn't know how much destructive power this thing was, just the crossbow arrow next to the giant crossbow that was as thick as an adult's arm, he could completely think of his destructive power, right?

The exquisite devices of the giant crossbow base dazzled Lin Xuan when he saw it. The goblin design is absolutely exquisite. Lin Xuan walked around the city wall again, and found that this city wall was not just what he saw in front of him, it should be said that there was something inside.

Lin Xuan found several entrances to the center of the wall. Lin Xuan didn't say a word, and walked in directly. Typical staircase building. But when he came to the first passage, Lin Xuan was immediately excited. The Steel Capital is the best defended city, and it also has the saying that it will never fall, of course, it is not absolute, but at least in Lin Xuan's eyes now, this Steel Capital is indeed worthy of this title.

In front of him was the outermost part of the city wall, Lin Xuan walked in, and was surprised to find that there were various sound transmission equipment in each passage. When he came to the front, Lin Xuan was suddenly stunned by what was in front of him. It's like a cab. Inside are various mechanical devices. Mechanical crossbows, and long-lost soul guide cannons.

Lin Xuan left this control room and walked towards the other control rooms. To Lin Xuan's surprise, every control room had the same device. Because there was no shooting hole in the room, Lin Xuan studied it excitedly.

Next to the chair in the room, Lin Xuan found a red button on the table, and without saying a word, he pressed it directly. Immediately after, Lin Xuan was surprised to find that the wall in front of him was moving to both sides, and there was also a vision window in the last three shooting holes, Lin Xuan was pleasantly surprised to find that this vision window was folded and rowed, and the outside was like a baffle, if you didn't look carefully outside, you really couldn't see it. Although the magic cannon in the room is only small, it also has the destructive power of a sect-level powerhouse with all its might.

Lin Xuan closed his eyes and imagined for a moment, if tens of thousands of such magic cannons were fired at the same time, I am afraid that even ordinary legions would not be able to survive, right? These mechanical crossbows, Lin Xuan studied them carefully, and originally wanted to dismantle one and take it back for study, but in the end, he was surprised to find that if it was forcibly removed, I am afraid that the entire device would be scrapped. In desperation, Lin Xuan could only press the red button again, and the room returned to its original appearance.

Lin Xuan came to the stairs again and walked down. Lin Xuan was definitely quite excited at this time. Because in the memory of the dwarf king, there is something that Lin Xuan has not seen yet, and that is the mechanical legion of the goblin clan. Lin Xuan walked about five floors, and the structure was no different from the top floor.

It wasn't until the tenth layer that Lin Xuan came to the last layer. However, there were no rooms here, but there was a straight passage to the outside of the city. The other side leads to the city. If Lin Xuan wasn't wrong, this passage should be the passage for the dwarves in the city to escape. Lin Xuan didn't go out, but walked in the direction of the city.

After walking for about twenty minutes, Lin Xuan was surprised to see a large door. The gate is five meters high. Without saying a word, Lin Xuan directly pushed the door open, although it was very heavy, but for Lin Xuan, it was completely possible to push.

When he entered the room, Lin Xuan's eyes lit up, because there was a row of huge humanoid machines three meters high neatly arranged in front of him. Lin Xuan probably counted it, and there were about a thousand. If this is the case, the passage just now is not just for the citizens to evacuate, it should be to let these large machines enter the back of the enemy army. Lin Xuan sighed and continued to walk inside. It wasn't until he came to the end that Lin Xuan saw several passages to the ground.

Lin Xuan walked up and found that the exit was blocked by an iron plate. Pushing through the iron plate, he came to a huge wall.

After Lin Xuan came out, he restored the iron plate to its original state and found that this was an invisible tunnel. Several other tunnel exits are also around, and this is the square outside the palace walls, and the ground is paved with the same iron plates. Because the iron plate is more than 20 centimeters, if you step on it, you won't feel the hollow underneath if you don't pay attention.

Entering the palace, Lin Xuan was surprised to find that there seemed to be a human breath here. Cancel the martial soul directly, and then enter softly. Close your eyes and run in the direction of the signs of life.

In the distance, a faint light came from afar. The light came from a room. Lin Xuan approached softly, and when he came to the front of the room, he was surprised to find that this room was the palace of the Imperial City, and at this time, there were about a hundred people in the palace.

In the center of the palace was a bonfire, and the most group of people had their backs to the door of the main hall, facing an old man.

Lin Xuan was surprised to find that these people were obviously dwarves, but they were completely different from the current dwarves and the dwarves in the memory of the dwarf king, but without exception, none of them had cultivated their fighting spirit, and their aura was not very strong, which was why Lin Xuan didn't find them when he came in.

The tallest of these dwarves should not be more than one meter two when they stand up, while the average adult dwarf in the outside world can reach about one meter three. The dwarves in front of him were pale, and they were all very thin, and Lin Xuan even doubted that they could open the stone slabs of those secret passages in the square. The old man was obviously telling the hundred people in front of him something. Lin Xuan listened carefully and found that these people were speaking ancient languages.

"Could it be that these dwarves are the dwarves who didn't escape when the Steel Capital sank in ancient times?" Thinking of this, Lin Xuan began to listen carefully to the old man's words.

The old man's voice was not small, and Lin Xuan, who had inherited the memory of the dwarf king, could barely understand it. "Our Dwarven King alone takes on countless dragons, you, children. You may not know that dragons are the size of a small mountain, and their strength is quite strong. Just spit out a mouthful of flame and it can burn everyone we have here. But the mighty dwarven king took the dragon sword and finally killed many dragons, and then found our elven friends to sink our city into the ground. But the king promised us that he would return. ”
