In front of it was a mountain of stones, all of which were bare and rocky, with no weeds.This mountain is not only tall, but also big, and even more terrible, it has almost no slope and is straight up and down.

Feng Yuheng looked up, and his chin was so painful that he could see a little mountain tip at the end of the cloud. He could not help but sigh: "It stands like this mountain, right?"

Xuan Tian Ming explained to her: "This mountain is called Xu Tian, ​​it is the highest mountain in Pingxu Mountain Range, and it is also the most dangerous. . "

She asked curiously: "What about you? Can you turn it over with light skills?"

Xuantian Ming shook his head, "We are not gods, even if we borrow light power to turn the mountain, we also need to step on many times in the middle. What's more, although the barrier mountain we turned over is still high, it is still less than 30% of the virtual sky mountain. The mountain into the cloud No matter how powerful the master of light skills is, he ca n’t get over it even if he is exhausted. "

"It turned out to be this way." Feng Yuheng still looked up with his head, and he was pondering, "You said, this camp is not far from the capital, such a high mountain, it can be seen in Jingli Ah, why have I never noticed? "

Xuan Tianming pointed to the front and told her: "The capital is in the direction of the back of the mountain. There is a big river over there. The air is wet all the year round, and the mist rises directly to the cloud, which just covers the mountain."

Feng Yuheng only felt miraculous when he heard it, and now he was shocked just by the foot of the mountain.However, the more shocking thing is yet to come. I saw Qian pointing at the big stone mountain in front of her and told her: "The county master, the Xutian Cave is inside this big mountain."

"Well?" Feng Yuheng froze directly, inside the mountain?Is it possible ... "This mountain is empty?"

Xuan Tianming looked at her stupidly and could not help laughing, and said softly: "If you are really curious, you can uproot this mountain, put it in your sleeve, and take it back to study slowly."

She shook her head again and again: "No, no, my sleeves are not so big, this is a mountain!"

In his speech, Qian Li had already taken a few steps forward.There were heavy soldiers in front of her. She looked carefully and found that the mountain directly opposite seemed a little different, but she couldn't tell the difference. She could only push Xuan Tianming and walk forward with Qian Li .

Finally, the mountain was within reach, and the soldiers who guarded the mountain saw that they were coming, and quickly kneeled to salute.Xuan Tianming called them up and gave a light command: "Kaishan." Seeing dozens of soldiers rushed forward together, they pushed towards the mountain together.

Feng Yuheng caressed her forehead, and heard of Yugong Yishan in the fable story. Now she sees a realistic version of the soldier pushing the mountain. It's a little exciting to think about it!

At this time, listening to the "Boom" sound, these soldiers were pushed openly on the mountain, and then the movement of the soldiers continued. The gap became larger and larger, and finally a giant stone gate was formed.

The door opened by the mountain was so huge that it was quite shocking when I saw it with my own eyes.In such an era without any mechanical production tools, it is not easy to open such a mountain gate.

But it was not easy to stay behind. As soon as the mountain gate opened, the soldiers immediately returned to their seats.Qian Li made a petition to everyone, and then strode forward, leading the way to the mountain gate.

Xuan Tian Ming pinched Feng Yuheng's little hand and said, "Let's go, let's go in too, let you see this legendary void sky cave."

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

The cool wind came straight and made her tremble with a blow.Suddenly remembered the natural karst cave in the southern area of ​​the previous life, which was also hollowed out and built.She also followed the tour group for a visit. It was summer, which was as cold as winter, but as beautiful as a fairyland.

Looking at this place again, the Xutian Mountain that soared into the sky was hollowed out as high as a seven-story building in the 21st century, and then various strange buildings were built in this hollow mountain.She noticed that there were still winding ladders around the mountain walls, there were patrolling soldiers walking around, and there were guardhouses, and the five steps were a tall one. The soldiers standing on it should be able to see clearly. The whole picture in the sky cave.

This is just a part that can be seen at a glance. There are many passages around, I don't know where to go.

Someone had already stepped forward to meet, and after saluting, they said: "The sixteen blacksmiths and the apprentices they brought were already waiting in the furnace. Will the general go there to see them, or call them over?"

Xuan Tianming said: "Let's go to the furnace."

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

Feng Yuheng hasn't recovered from the shock, Xuan Tianming has begun to tell her about the origin of the Xutian Cave-"This is built by the emperor of the founding father of Dashun. The mountain was built to such a degree. Later generations of monarchs are devoted to the construction of the Xutian Cave, which is more important than the repair of their own tomb. use."

Feng Yuheng can imagine the perseverance of the ancient people who poured into a great building from generation to generation, but she couldn't understand what was the purpose of hollowing out such a mountain?

Xuan Tian Ming knows that she understands and understands in her heart, and then she proactively said: "In fact, at the beginning of Dashun's capital, it was built to avoid disasters. At that time, Dashun's land was not as vast as it was. There is a lot of waste in the ups and downs, and the surrounding four countries are watching, and the country will be slightly destroyed. So, the monarch has to choose a place in the suburbs of Kyoto that is easy to defend and difficult to attack. The mention of the heavenly cave was raised at that time. The previous monarchs of Dashun did not live long. After three generations, the national crisis was not completely lifted, so this virtual heaven cave was dug. Until the fourth monarch After he succeeded, Jiangshan was firmly seated, but building it has become a habit and a belief. "

Feng Yuheng understood, "Xutian Cave has become a symbol, as long as it is good here, the monarch can be at ease, and it also means Dashun Cathay. Now, Dashun is already the most powerful country of Middle-earth, with all the borders There are heavy soldiers to guard against, even if there is a war, it must be desperate to go to the battlefield with real swords and guns, and the monarch will naturally no longer want to hide in the virtual sky cave. So this place is cheaper for you, right? "

Xuan Tianming corrected her: "It's cheaper for us. I chose the steelmaking site here. I'm afraid that in the future, this place will become the place where you spend the most time every day."

Feng Yuheng smiled, "Yes, I like it here."

During the talk, the crowd had reached the soldier's so-called furnace.The place is an independent space, connected by a trail to the main cave outside. The trail runs in, which is this small cave.

Said a small cave, it is also compared with the big cave outside. In fact, this cave is not small at all. According to Feng Yuheng's calculation, there must be at least 200 square meters.Numerous holes were dug around the mountain, and some people have already set up iron-making furnaces there.

Qian Qian clapped his hands to the people in this furnace and shouted, "Everyone came over to see our general and the Ji'an County Master!"

Everyone knows that the general of the Northwest Army is the most beloved nine princes in the saint today. Everyone also knows that the owner of Ji’an County is the future concubine of the nine princes. It is also the god doctor who is said to be more powerful than her grandfather Yao Xian. Everyone knows that the only person who can make steel in Dashun is the owner of Ji'an County.

So as soon as they heard that they were coming, sixteen blacksmiths and their apprentices came up together, and they bowed down on their knees, and said in their mouths: "His Highness County Lord Chitose Chitose!"

Feng Yuheng first heard that someone had brought her when she shouted Chitose, and she was a little uncomfortable.Xuan Tian Ming is naturally accustomed to this scene, raising his hand and saying, "Get up!"

People stood up tremblingly, Feng Yuheng looked at the blacksmiths, most of them were old, and the youngest appeared to be forty-five years old.The apprentices they brought were very young, and most of them were teenagers.

Looking around, there are many tools on the side of the furnace, including a large wind box, and charcoal and iron charcoal.After all, they are blacksmiths, all preparations are made according to iron, but the tools are very complete and very professional.

She took the initiative and asked those people: "Do you know what you did to find you here?"

The blacksmiths nodded one after another and answered, "I know, it's making something called steel."

The courageous asked: "I heard that the thing called steel is very hard and can break the iron like mud. Is that true?"

He was sure to ask, everyone opened his eyes, waiting for Feng Yuheng's answer.

She deliberately did not answer immediately, but took the opportunity to observe the eyes of these people.All sixteen looked down and nodded in satisfaction. They were indeed the best blacksmiths. Although they did not see their craftsmanship, this pure fanaticism in the face of new and good things was pretending not to. from.Only those who have absolute enthusiasm for their profession will show such an attitude when they hear that they can further improve their realm. These blacksmiths are all such people.

She let go of her heart a little, and made steel, fearing that she only had craftsmanship and no fanaticism.No one in this era has ever been in contact with real steel. The first refining is likely to fail with ten, twenty or even hundreds of furnaces.Or without a firm conviction and perseverance, you can't bear this temperament at all, and you can't bear such torture.What is also needed is such a person, even if the craft is not good enough, she teaches little by little, as long as the passion is still there, everything is possible.

She told everyone: "It's a bit exaggerated to say that breaking iron is like mud, but the toughness of steel and iron is indeed very different. Steel is a metal that is harder than iron. Steel is an alloy, and iron is a separate texture. The main difference between the two is the amount of carbon. To put it bluntly, steel is an iron-based alloy with a carbon content greater than or less than a fixed value. I say this Maybe you do n’t know— "she said while handing her steel knife to Bai Ze." Bai Ze, you try it for everyone to make everyone understand the difference between steel and iron. "

Bai Ze was very happy to take the knife, and he came forward to try it, but he heard an old man suddenly shout in the blacksmith heap: "Wait!"
