Chapter 1369： Great treasure, black iron mine!

"What? Xuan Iron Mine? Lin Feng, could you make a mistake? Didn't you say that when refining flying swords? Xuan Tie was a precious refining tool even in the ancient Xiuzhen era. Materials, why is there in Zhi'an City here?"

Hearing Lin Feng's exclamation, Li Yutong exclaimed unbelievably. WWWW.SUIMENG.lā,. Her current understanding of Xiuzhen is based on what Lin Feng taught her, so she also knows that profound iron and other refining materials are precious even in ancient times, and are not ordinary monks in Qi training period. Can be obtained in large quantities.

But now, according to what Lin Feng just said, the place in front of him was not a piece of two black iron, but a piece of black iron ore. What concept is this? If you are in the realm of cultivation, the mountain'gate' where such a piece of profound iron ore is located is enough to develop a powerful cultivation'gate'.

In fact, the world of comprehension is the same as the current human society, everything is about talents and resources. A talented monk, with enough resources such as cultivation techniques, pill ‘medicine’, materials, etc., will inevitably have a strong cultivation base and combat power.

In addition to exercises and pill ‘medicine’, various refining materials are also one of the important cultivation resources. If this large piece of black iron mine was put in the realm of cultivation, once it was discovered, it would definitely be a password to avoid leakage of such important news. Because once this news is leaked out, it may be known to other ‘door’ factions and fight for it.

However, in the current earth where resources are exhausted and the environment is severely polluted, cultivation resources are even rarer in ancient times. It is simply incredible to be able to find such a large area of ​​profound iron ore in this era of the end of the law.

"I also think it's incredible. Sister Tongtong, think about it. The two darts we'get' from the hand of the warrior who played with the hidden weapon this time are just so little black iron. I don't think it is precious anymore. You can use it. It’s time to build the Fengtong sword of the Grade Spirit Tool. Now there is an entire mysterious iron mine here! Although I don’t know how big the scale is, it’s more than enough to make at least one thousand and ten thousand flying swords!"

Lin Feng was still in shock. His spiritual sense kept digging deep underground, trying to find out how big this mysterious iron mine was.

However, the texture of the black iron ore was completely different from ordinary rocks, and Lin Feng's spiritual sense could not go deep. For example, Lin Feng’s spiritual sense can be extended 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 10 meters, but if it is a black iron ore, it can go one or two meters deep. As if hitting the wall, he was bounced back.

"How could it be? Lin Feng, my spiritual sense can't go deep into the ground even one meter, this mysterious iron mine is so powerful."

Li Yutong's spiritual consciousness is not as strong as Lin Feng, so she can't even go one meter deep.

"Sister Tongtong, this fully proves that my judgment just now is not wrong. The density of black iron is about ten times stronger than that of ordinary'fine' iron, so our spiritual sense cannot pass through the dense metal atoms. But it is also because In this way, Xuan Tie possesses some very special chemical and physical'sexual' qualities, which are especially suitable for building flying swords and some body protection spirit weapons."

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

"How is it? Lin Feng, how big is this mysterious iron ore?" Li Yutong asked behind him.

"Very large! At least the range of my spiritual sense detection just now is so large..." Lin Feng said with a smile.

"That's great! With so many profound irons, don't we want how many flying swords, how many flying swords do we have?"

After refining the Fengtong sword, Li Yutong has always wanted a flying sword of his own, but because the materials are scarce, and their current cultivation base is not high, if they simply refine the spirit weapon, it will cost more resources Up. Therefore, there has been no refining of spirit weapon-level flying swords for a long time, but if you now have so much profound iron, you don't need to worry about resource consumption.

"Haha! You don't need so much profound iron to make flying swords. I think these profound irons are enough to make spaceships!"

Today, I was able to discover the Xuan Iron Mine of Tianmafeng Mountain. It was a complete surprise. If it weren’t for the investment in road construction here, Lin Feng would probably not find it buried underneath even if he passed by here a hundred times and a thousand times. Of black iron ore.

However, when he thought of the problem of road construction in tourist attractions, Lin Feng frowned and said, "No! Sister Tongtong, if you say...this underground is really all black iron mines, then I think it is not a problem at first. Now it’s a big problem."

"Ah? What's the problem? Lin Feng, shouldn't you say... the problem of road construction in tourist attractions?"

Li Yutong’s heart sank, and he immediately understood, “That’s really a big problem. After all, it’s hard for me to refine this mysterious iron with pure'yin' fire, let alone other modern machinery. It is a method of other cultivators, it is easy to deal with ordinary rocks and ores. But... if you deal with profound iron,..."

"En! This is a headache. The texture of the profound iron ore is too hard, and it is difficult for my vitality fire to melt. Let alone open the way, we have to dig out some of the profound iron to make it. I don’t know how to make a flying sword."

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

Whether you use it or not Xuan Tie is here, it doesn't move, and you can't ‘make’ it.

"Then this is troublesome. If the mountain roads here still cannot be opened up, then the plan for the entire tourist attraction will really be stranded. Almost all the natural landscapes are behind the Tianmu Peak! We can never learn from the domestic Some scenic spots, build some sky roads out of thin air?"

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

What is Tianlu?

The sky roads mentioned by Li Yutong are some places with very complicated terrain in China. When other constructions cannot be carried out, suspension bridges or piers can only be built out of thin air, and roads made without relying on any mountain 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 annual maintenance cost is also very high, and it is difficult to guarantee 100% safety. Therefore, unless it is a last resort, the construction unit will never adopt such a scheme.
