Putting aside other things, Qingyang's efficiency in digging polar flint is still very high. In less than ten days, he dug 70 or 80 polar flints, occupying almost half of the space inside the fire gourd, so many polars. The flint is piled together, forming an extremely terrifying high temperature inside the fire-fighting gourd. Qingyang put his fingers into it. Even with the protection of the wind and fire order, Qingyang’s fingers were instantly burned. It can be seen that the temperature inside is high. How high.

But think about it, the reason why the temperature of this Yinfeng Jihuo cave is high is because the cave is buried with ground flint and polar flint. The reason why the temperature in the depths of the cave is higher than other places is also because the proportion of polar flint inside is higher. High, now that a large number of extremely flint stones are piled together, the resulting temperature must be extremely terrifying, that is, the fire-driving gourd made by Master Shihan is good enough, otherwise Qingyang really doesn’t know how to take these extremely flint stones away. .

　　 In addition to the extremely flint, in the caves Qingyang dug, there are also two or three hundred pieces of flint piled up. The value of this thing is not high and there are many, and Qingyang doesn't even bother to pick it up. Only those low-level cultivators, or those who lack the ability to reach the depths of the inner cavern, can see this thing.

The lower half of the interior of the fire gourd is used to store polar flint. Seventy or eighty polar flints have already occupied half of the space. The upper half contains the fire control system refined by Master Shi Han. It is extremely easy to use. Qingyang Find a beam of extreme fire in the cave and put it in. The extreme fire is stored in the fire-propelling gourd. From now on, the extreme fire stone below will continuously provide energy to ensure that this beam of extreme fire will not be extinguished. When making alchemy, Qing Yang only needs to control the fire control system above to adjust the size of the extreme fire to meet the needs of alchemy.

　　 If you don’t use it frequently, these polar flints are enough to support Qingyang for more than ten years. If the effect is insufficient in the future, just replace the polar flints inside.

　　 Seeing that there are seventy or eighty pieces of extremely flint in the fire-extinguishing gourd, this time the task is considered to be more than half completed, and Qing Yang decided to focus on the Jinling Iron Mine in the future. It's not that there is no need for extremely flint, but that this matter is not too urgent, there is no need to focus on this, it is enough to dig by the way when looking for other things.

Jinling Iron Ore is an ore used to refine Jinling Iron, a refining material. It can be seen from the name that Jinling Iron is a metallic refining material. Ordinary Jinling Iron is nothing unusual. There are many in the shop of Jiuxiancheng, and you can buy several copies of a spirit stone.

It’s strange that this kind of iron ore has growth potential. During the formation of Jinling Iron Ore, every hundred years, a unique murderous aura will be formed inside, and this murderous aura will always be attached to the material. This murderous aura can It doubles the sharpness of attacking magical or spiritual weapons, and takes the advantage in battle. Therefore, the more murderous aura in the gold spirit iron mine, the higher the value.

　　 Ordinary non-murderous gold spirit iron ore, a piece of spirit stone can buy several copies, but this thing is not very useful, and it can also refine some low-level magic tools used by cultivators in the open vein realm.

The metallic magic weapon is the main kill, and the metallic magic weapon with murderous intent is more powerful. Therefore, the murderous gold spirit iron is particularly sought-after. The gold spiritual iron within ten kills is generally used for refining. The high-level magic weapons or low-level spiritual tools used by the Qi monks, and the golden spirit iron within the hundred kills, can be used to refine the high-level magic weapons used by the foundation-building monks, or the magic weapons used by the golden core monks.

　　 As for the golden spirit iron above the hundred kills, the magic weapon that is refined is even more powerful. It is the material used to refine the superior magic weapon, even the golden core monks dream of it. It’s a pity that this kind of thing is too rare. Among dozens of ordinary gold spirit irons, it’s good to have one ten-kill gold spirit iron, and dozens of ten-kill gold spirit irons can’t produce one hundred-kill gold spirit. Iron, and gold spirit iron with more than one hundred kills, it is rare to find one piece of gold spirit iron with one hundred pieces and ten kills.

This cave in the heart of the earth is a good gold spirit iron mine. Every time the Yinfengjihuo cave is opened, many monks come to try their luck, but after so many years, most of the dug are less than ten kills. Jin Ling Tie, one hundred kills is relatively rare, and the one above one hundred kills is extremely rare. As for the one thousand kills Jin Ling Tie, it is even more unheard of.

　　 Of course, even if someone digs it out, it’s impossible to publicize it with great fanfare. Isn’t that trouble for yourself? But this also illustrates the rareness of high-level spirit mines.

Qing Yang was not looking for the golden spirit iron to get rich, but the five element magic weapon he was preparing to refine still lacked a main metal material, although before coming, he also explained that Master Shi Han helped him pay attention to materials that can be used. Where is it so easy to find? He is not willing to use ordinary materials instead, so he has to find a way to find the best materials.

This gold spirit iron is actually a very good material for refining metallic magic weapons~lightnovelpub.net~ Of course, the gold spirit iron below a hundred kills is definitely not good, and the low-level magic weapon material Qingyang can't be seen, he hopes Can find a piece of gold spirit iron ore with 300 kills or more than 500 kills, so that the metallic magic weapon refined can barely match oneself.

　　 As for the higher ones, Qing Yang couldn't even think about it. The monks in the Ancient Wind Continent hadn't obtained such good gold spirit iron for so many years. How could it be possible to get such good materials when he first came here? With a few hundred kills, Qing Yang would be content.

In fact, in the previous few days, Qingyang has dug a lot of gold spirit iron ore, but they are all ordinary gold spirit iron, which contains only a dozen pieces of murderous intent, and only one piece of more than ten kills. It is very reluctant to refine lower-grade magical tools, and it is almost of no use to Qingyang. The combined value of all these materials will not exceed the value of a hundred spirit stones. It can be seen how difficult a good gold spirit iron is, if Qingyang wants to obtain one. The difficulty of using the golden spirit iron is not as high as normal.

But here is the depths of eight thousand feet in the heart of the earth. Very few monks can come here. Maybe they can get better gold spirit iron, seven hundred kills, nine hundred kills, or even thousands of kills. For Qing Yang, of course, the more murderous aura contained in Jin Lingtie, the better.

I thought that I had already collected the materials for the formation of alchemy, and soon after I went out, I would be able to refine the golden core, and even become a golden core monk. I thought that I had already gathered four kinds of magic weapons for the attributes of the five elements, and now only the last one was left. After forming a pill by himself, he can use five kinds of rare materials to cast the five-element sword formation to kill the Quartet. Qing Yang's heart is full of enthusiasm. together.
