There is a rocky mountain in front of it, bare and full of rock walls without a trace of weed. The mountain is not only tall, it's big, and, more importantly, it has almost no slope, it's completely straight up and down.

Feng Yu looked up, his chin was so sore that he could see a little bit of the mountain tip at the end of the cloud. He had to exclaim: “Stand in awe, is that what you mean? ”

Xuantian Zhui explained to her: “This mountain is called the Idyllic Sky, it is the highest mountain in the Ping Dynasty Mountains and the most dangerous one. The mountain rises vertically and peaks into the sky, rocky on all sides, with no possibility of climbing. ”

She asked curiously, "What about you? Can you flip over with light work? ”

Xuantian shook his head, “We are not fairies. Even if we use light power to climb mountains, we need to tread many times along the way. Besides, the barrier mountain that we have turned over is still less than 30% of the mountain. The mountain in the clouds is just another powerful master of light kung fu, tired to death can not be turned over. ”

“So that's it.” Phoenix still looked up, thinking, "You said," This camp is not far from the capital. The mountains are so high that you can see them in the capital. Why didn't I ever notice? ”

Xuantian Mingtian pointed forward and told her: "In the direction of the back of the mountain, there is a great river over there, the air is wet all the time, the water fog rises directly to the cloud, just to cover the mountain. ”

Phoenix sounded amazing, and now she's at the foot of the mountain, which is also extremely shocking. However, the more shocking thing was still behind her, when she saw that the big rock mountain in front of her was pointed in the money and told her: "County master, the vain cave is inside this mountain. ”

“Hmm?” Feng Yu just stunned, in the mountains? Could it be... “This mountain is empty? ”

Xuantian looked at her like a fool and had to laugh. She said softly: "If you're really curious, you can take this mountain up, shove it in your sleeve, and take it back to study. ”

She shook her head. “No, no, my sleeve is not this big. It's a mountain! ”

In the talking room, the money has taken a few more steps forward. Heavy soldiers guarded ahead, she took a closer look and found that the mountain body on the opposite side seemed a little different, but she couldn't say where it was, but pushed Xuantianzhuo, and went forward with the money.

Finally, the mountain body was within reach. At first sight, the sergeant guarding the mountain came and hurried to his knees to pay his respects. Xuantian shouted them up and said softly: "Kaiyama.” We saw dozens of generals pouring up and pushing towards the mountains together.

Feng Yu touched her forehead, the fable story has heard of the foolishness of moving the mountain, now she sees a realistic version of the general pushing the mountain, think about it a little excited!

At this point, listening to the "bursting" sound, the mountain body was pushed open by these generals, and then the action continued, the gap became bigger and bigger, eventually forming a boulder door.

The doors opened by the mountains are so enormous that they are still quite a deterrent when seen with one's own eyes. In an age without any mechanical means of production, it is not easy to open such a mountain gate.

It was not easy to stay behind, but the mountain gate opened and the soldiers returned to their positions. The money made a request to the crowd, then took a big step forward and took the lead into the mountain gate.

Xuantian pinched Feng Yuxiang's little hand and said: "Let's go in and show you the legendary cave. ”

With twelve points of curiosity, she pushed the wheelchair forward and followed the money into the mountain gate.

The cool wind came up and blew her a shiver flat. It suddenly reminded me of the natural melting hole in the southern part of the previous generations, which was also built by emptying the mountain bodies. She also went on a tour with the tour group, where it was cold as winter and beautiful as a fairy land in the summer.

And then here, the skyscraped mountain emptied seven floors in the 21st century, and then built all sorts of strange buildings in this hollow mountain. She noticed that there were revolving steps around the mountain walls, with patrolling generals walking and walking up and down, and posts. Five steps was a tall one, and the soldiers standing on it should be able to see the full picture of the void cave.

And this is just a glimpse, and there are lots of paths around, and I don't know where it leads.

There was already a greeting inside, and after the salute, he said, "Sixteen blacksmiths and their apprentices are already waiting in the furnace. Should the general meet them over there or send them over? ”

Xuantian said, "Let's go to the furnace. ”

The man nodded and took the initiative to lead the way forward.

Phoenix has not returned from the shock, Xuantianzhuo has begun to tell her about the origins of the empty cave - “This is built by Emperor Dashun Kai, and it took Dashun 30% of the labor to dig this mountain to such an extent. Yet successive generations of kingdoms are committed to the construction of empty caves, which is more important than the repair of their own mausoleums. It wasn't until my great-grandfather's life that this hollow was truly built that it could be put into use. ”

Phoenix can imagine the resilience of the ancients pouring on a great building from generation to generation, but she can't understand, what is it about emptying a mountain like this?

Xuantian knew what was in her heart and took the initiative: “In fact, at the beginning of Dashun Capital, this place was built to escape the scourge. At that time, the land of Dashun had not yet been so vast, the long and constant battle had come down, the country had been raised to waste, and the surrounding four tigers looked at it, and there was a slight disaster of annihilation. Therefore, the King had to choose a defensible place near Kyoto as a place to save his life at a critical moment, when the idea of digging a cave was raised. Dashun's predecessors have not lived long. After three generations, the national danger has not been completely eliminated, so this empty cave has been dug. Until the fourth king took office, Jiangshan was steady, but building this place became a habit and a faith. ”

Feng Yu understood, “The idyllic cave has become a symbol. As long as this place is good, Guo Jun can feel at ease. It also means Dashun Guotai. Now, Dashun is the most powerful country in the Middle East. All the borders of the Quartet are heavily guarded. Even if there is a real war, it must be the battlefield of the true sword and gun. Naturally, the King will no longer want to hide in the vain cave. So this place is cheap for you, right? ”

Xuantian corrected her: “It's cheap for us. I chose steel-making to be one of the most expensive places to spend your day in the future. ”

Feng Yu chuckled, “Nice, I like it here. ”

And in the midst of the speech, they went to what the general called the furnace. The place is an independent space, connected by a trail to the main cave outside, and the trail leads in, which is this little cave.

Said it was a small cave, which is also compared to the big cave outside. In fact, the cave is not small at all. According to Phoenix's calculations, there must be at least 200 square meters here. Numerous wallholes have been drilled around the mountains, where iron stoves have been filled.

The money clapped at the people at the furnace site and said out loud: "Everyone, come and meet our general and Ji 'an County lord! ”

Everyone knows that the general of the Northwest Army is the favorite nine princes of the emperor today. Everyone also knows that the lord of Ji 'an County is the future princess of the nine princes. He is also the shen doctor who is said to be more powerful than her grandfather Yao. Moreover, everyone knows that Dashun is the only one who can make steel, which is the lord of Ji 'an County.

So I heard that they had come, and sixteen blacksmiths and their respective apprentices came up, kneeling and praying, saying: “Your Highness, the county master is a thousand years old! ”

Feng Yu heard for the first time that someone had taken her with him when he shouted a thousand years old, and he was not comfortable with it. Xuantian Zhui was naturally too used to this scene. As soon as he raised his hand, he said: "Get up! ”

People rose up fearfully, and Feng Yu looked at the blacksmiths, most of them older, and the youngest appeared to be forty-five years older. By the time they brought their apprentices, they were young, mostly teenagers.

Measuring around, there are tools on the side of the furnace, big windboxes, charcoal and iron charcoal. After all, they are blacksmiths, and everything is prepared according to iron, but the tools are very complete and professional.

She opens her mouth and asks the people, "Know what it is to bring you here? ”

The blacksmiths nodded and replied, "Yes, it's a thing called steel. ”

And he had the audacity to ask, “I heard that something called steel is very hard, and it breaks iron like mud. Is that right? ”

He asked everyone to open their eyes and wait for Phoenix's answer.

Instead of responding immediately, she took the opportunity to observe the eyes of these people. Sixteen of them all looked down and nodded to their satisfaction. They were indeed the best blacksmiths. Although they did not see their craftsmanship, this sheer fanaticism in the face of new and good things could not be faked. Only those who have an absolute passion for their profession will show such an attitude when they hear that they can further improve their situation, as these blacksmiths do.

She let go of her heart slightly, steelmaking, afraid only of craftsmanship and not fanaticism. No one has ever come into contact with real steel in this era, and for the first time, there is a good chance that even ten, twenty or even hundreds of furnaces will fail. Or not having a firm conviction and commitment, not being able to withstand this personality at all, and not being able to endure such suffering. And that's the kind of person who, even if the craftsmanship is poor, makes a big deal out of her, so long as the enthusiasm is still there, everything is possible.

She told people, "It's a little exaggerated to say that iron is cut off, but there's a big difference between steel and iron toughness. Steel is a harder metal than iron. In theory, steel belongs to alloys, whereas iron is a separate texture. The main difference between them is the carbon content. To be blunt, steel is iron-based alloys with carbon content greater than or equal to a fixed value. I don't know if you know ——” She said it while handing over her steel knife to Shirazawa, "Shirazawa, why don't you go give it a try and let everyone know where the difference is between steel and iron. ”

Shirazawa was happy to take the knife. She was about to go up and try it, but she heard it in the blacksmith's pile. An old man suddenly shouted: "Wait! ”
