"What?Xuantie Mine?Lin Feng, could you be mistaken?The last time you refined the flying sword, didn't you say it?Xuantie was a relatively precious refining material even in the ancient cultivation era, how could there be one here in Zhi'an City?"

Hearing Lin Feng's exclamation, Li Yutong also exclaimed incredibly. Pen & Fun & Pavilion www.biquge.info her current understanding of cultivation is based on what Lin Feng taught her, so she also knows that refining materials such as Xuantie are relatively precious even in ancient times, and they are not something that ordinary Qi cultivation period cultivators can obtain in large quantities.

But now, according to what Lin Feng just said, what is under the place in front of him is not a piece or two pieces of dark iron, but a piece of dark iron ore. What kind of concept is this? If it is in the cultivation realm, just such a mountain gate where the Xuantian Mine is located is enough to develop a powerful Xiuzhen sect.

In fact, the cultivation realm is the same as the current human society, and everything is about talent and resources. A gifted monk, coupled with sufficient resources such as exercises, pills, and materials, will inevitably have a strong cultivation and combat power.

In addition to exercises and pills, various refining materials are also one of the important cultivation resources. If this large area of Xuanjian Mine is placed in the cultivation realm, once it is discovered, it is absolutely necessary to issue a gag order to avoid the leakage of such important news. Because once this news leaks out, it may be known by other sects and compete for it.

However, in the current earth where resources are depleted and the environment is seriously polluted, the resources of cultivation are even rarer than in ancient times. It is simply inconceivable to be able to find such a large area of dark iron ore in this era of the end of the law.

"I thought it was incredible, too. Sister Tongtong, think about it, the two darts we got from the martial artist who played with the hidden weapon last time were only so little bit of dark iron, and they already felt that they were extremely precious and could be used to create the Fengtong Sword of the highest grade spiritual weapon. There's a whole black iron mine here! I don't know how big it is, but at least the materials for making a thousand and ten thousand flying swords are more than enough!"

Lin Feng was also still in shock, his spiritual sense continued to dig deep into the ground, wanting to find out how big the scale of this dark iron ore was.

However, the texture of the dark iron ore was completely different from ordinary rocks, and Lin Feng's spiritual sense could not go too deep at all. For example, Lin Feng's spiritual sense can expand to a distance of 100 meters in a straight line in the air, but if it is ordinary rock and soil, it can only go down to ten meters, but if it is a dark iron ore, if it is deep one or two meters, it will be like hitting a wall and being bounced back.

"How could it be? Lin Feng, my spiritual sense can't even go deep into the ground, this dark iron ore is so powerful. ”

Li Yutong's spiritual sense strength was not as strong as Lin Feng's, so she couldn't even go one meter deeper.

"Sister Tongtong, this fully proves that my judgment just now is not wrong. The density of dark iron is about ten times stronger than that of ordinary refined iron, so our spiritual consciousness cannot pass through the tight atoms of various metals. However, because of this, Xuantie has some very strange chemical and physical properties, which are especially suitable for crafting flying swords and some talismans. ”

After pulling out the Fengtong sword, Lin Feng walked around this mountain peak again.

"How is it?Lin Feng, how big is this piece of dark iron ore?" asked Li Yutong as he followed behind.

"It's very big! At least the range that my spiritual sense detected just now has such a large ......," Lin Feng said with a smile.

"That's great! With so much Darkiron, we don't have as many flying swords as we want?"

After refining the Fengtong Sword last time, Li Yutong has always wanted to have a flying sword of his own, but because the materials are relatively scarce, and their cultivation is not high now, if they simply refine the spirit weapon, it will be a waste of resources. Therefore, I have not been refining a spirit-level flying sword for a long time, but if I have so much Xuaniron now, I don't have to worry about resource consumption.

"Haha! You don't need so much dark iron to refine the flying sword, I think these dark irons are enough for refining spaceships!"

It was a complete surprise to be able to discover the Xuaniron Mine in Laofeng today today, if it weren't for the fact that he wanted to invest in the construction of roads here, Lin Feng would probably not be able to discover the Xuaniron Mine buried underneath even if he passed by here a hundred times and a thousand times.

However, as soon as he thought of the problem of building roads in tourist attractions, Lin Feng frowned: "It's not good! Sister Tongtong, if you say ...... If this underground is really full of dark iron ore, what I didn't think was a problem at first is now a big problem. ”

"Ah, what's the problem? Lin Feng, what are you talking about...... It's a question of road construction in tourist attractions, right?"

Li Yutong's heart sank, and he immediately understood, "That's really a big problem, after all, even if I use pure yin fire to refine this dark iron, it's more difficult, not to mention other modern machinery, even if it's the means of other cultivators, it's easy to deal with ordinary rocks and ores." But...... If you deal with Xuantie, you will ......"

"Yes, this is a headache, the texture of the iron ore is too hard, and it is difficult for my vitality fire to melt. Not to mention opening the way, even if we want to dig out some of the dark iron to refine the flying sword, we don't know how to start. ”

This is the huge problem that Lin Feng is encountering now, guarding Baoshan and not knowing how to use it.

Whether you use it or not, the dark iron is here, it doesn't move, and you can't move it.

"Then this is troublesome, if the mountain road here still can't be opened, then the plan of the entire tourist attraction will really be put on hold. Almost all the natural landscapes are behind Tianmu Peak! We can't learn from some scenic spots in China and build some heavenly roads out of thin air?"

Li Yutong said in a deep voice, "But the cost of such a road is higher, and the technical requirements are very strict." These are still secondary, the key is that our cliffs, if we build a heavenly road, it is extremely prone to all kinds of accidents. ”

What is a heavenly road?

The heavenly road mentioned by Li Yutong is a road made by some places in China where the terrain is very complicated, and when other construction cannot be carried out, suspension bridges or piers can only be built out of thin air, without relying on any mountains or other supports.

The cost of this kind of sky road is high, the risk factor is very high when it is built, and the maintenance cost is also very high every year, and it is difficult to have 100% guarantee in safety. Therefore, unless it is really a last resort, the construction unit will never adopt such a plan.
