"What? Black iron ore? Lin Feng, are you mistaken? Didn't you say that when you refined the flying sword last time? Black iron was a relatively precious weapon refining material even in the ancient era of cultivation.

,How come there is one here in Zhi’an City?”

Hearing Lin Feng's exclamation, Li Yutong also exclaimed in disbelief. Her current understanding of cultivation is based on what Lin Feng taught her, so she also knows about weapon-refining materials such as black iron, even in

It was also relatively rare in ancient times and could not be obtained in large quantities by ordinary Qi-training monks.

But now, according to what Lin Feng just said, what is under the place in front of you is not a piece of black iron, but a piece of black iron ore. What is this concept? If it is in the world of cultivation, there is such a piece of black iron ore.

The mountain gate where it is located is enough to develop a powerful cultivation sect.

In fact, the world of cultivation is the same as today's human society. Everything is about talent and resources. Talented monks, coupled with sufficient resources such as techniques, elixirs, materials, etc., will inevitably have strong cultivation and combat power.

.

In addition to exercises and elixirs, various weapon refining materials are also one of the important cultivation resources. If this large piece of black iron ore is placed in the cultivation world, once it is discovered, a hush-hush order will definitely be issued.

Avoid leaking such important information, because once this information is leaked, other sects may know about it and compete for it.

However, in the current resource-depleted and severely polluted earth, cultivation resources are even rarer than in ancient times. It is simply unbelievable that such a large area of ​​black iron ore can be found in this Dharma-ending era.

"I also think it's incredible. Sister Tongtong, think about it, the two darts we got from the warrior who played with hidden weapons last time only had so much black iron, but they were already considered extremely precious and can be used for

It’s time to make the Fengtong Sword, a top-grade spiritual weapon. Now there is an entire black iron mine here! Although we don’t know how big the scale is yet, there are enough materials to make at least one thousand and ten thousand flying swords!”

Lin Feng was still in shock. His spiritual consciousness kept digging deeper into the ground, trying to find out how big the black iron mine was.

However, the texture of black iron ore is completely different from that of ordinary rocks, and Lin Feng's spiritual consciousness cannot go too deep at all. For example, Lin Feng's spiritual consciousness can expand to a distance of one hundred meters in a straight line in the air, but

If it is ordinary rock and soil, it can only go down ten meters, but if it is black iron ore, it will be bounced back as if it has hit a wall if it goes one or two meters deep.

"How could it be? Lin Feng, my spiritual consciousness cannot even penetrate one meter underground. This black iron ore is so powerful."

Li Yutong's spiritual consciousness is not as strong as Lin Feng, so she cannot penetrate even one meter.

"Sister Tongtong, this fully proves that my judgment just now is correct. The density of black iron is about ten times stronger than that of ordinary fine iron, so our spiritual consciousness cannot pass through the dense metal atoms. But it is also because of this

, Black Iron has some very peculiar chemical and physical properties, and is particularly suitable for making flying swords and some protective spiritual weapons."

After pulling up the Fengtong sword, Lin Feng walked around the mountain peaks again.

"How's it going? Lin Feng, how big is this black iron mine?" Li Yutong asked from behind.

"It's huge! At least the range that my spiritual consciousness has just detected is this big..." Lin Feng said with a smile.

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

After refining the Fengtong Sword last time, Li Yutong has always wanted a flying sword of his own. However, because of the scarcity of materials and their low cultivation level, it would be a waste of resources to simply refine the spiritual weapon.

. So I haven’t been able to refine a flying sword at the level of a spiritual weapon for a long time, but if I have so much black iron now, I don’t have to worry about resource consumption.

"Haha! You don't need so much black iron to refine a flying sword. I think this black iron is enough to refine a spaceship!"

It was a complete surprise to be able to discover the black iron mine in Tianmu Peak today. If it weren't for the investment in road construction here, Lin Feng would never have been able to discover the mine buried underneath even if he passed by here a hundred times a thousand times.

Of black iron ore.

However, when he thought about the problem of road construction in tourist attractions, Lin Feng frowned: "No! Sister Tongtong, if...the underground here is really full of black iron mines, then I don't think it is a problem at first.

The problem has become a big problem now.”

"Ah? What's the problem? Lin Feng, are you talking about... the problem of road construction in tourist attractions?"

Li Yutong's heart sank and he understood immediately, "That's really a big problem. After all, even if I use pure Yin fire to refine this black iron, it would be difficult for me to refine it, let alone other modern machines.

It's the method used by other cultivators, and it's easy to deal with ordinary rocks and ores. But... when it comes to dealing with Xuan Tie, just..."

"Well! This is a troublesome problem. The texture of the black iron ore is too hard, and it is difficult for my vitality fire to melt. Not to mention opening a path, we have to dig out some of the black iron to smelt it.

I don’t even know how to make a flying sword.”

This is the huge problem Lin Feng is facing now, guarding the treasure mountain empty and not knowing how to use it.

No matter whether you use it or not, Xuantie is here. If it doesn't move, you can't move it either.

"Then this will be troublesome. If the mountain road here still cannot be opened, then the entire tourist attraction plan will really be shelved. Almost all natural landscapes are behind Tianmu Peak! We can't learn from this.

Are you going to build some sky roads out of thin air in some domestic scenic spots?"

Li Yutong said in a deep voice, "But such a sky road is more expensive to build, and the technical requirements are very strict. These are secondary. The key is that building a sky road on our cliff is extremely prone to various accidents."

What is the Heavenly Road?

The Tianlu mentioned by Li Yutong refers to some places in China where the terrain is very complex. When other construction cannot be carried out, suspension bridges or bridge piers can only be built out of thin air, without relying on any mountains or other supports to create roads.

The construction cost of this kind of skyway is high, and the risk factor during construction is very high. In addition, the annual maintenance cost is also very high, and it is difficult to have a 100% guarantee in terms of safety. Therefore, unless it is really a last resort, construction should not be carried out
