Other things aside, Qingyang's efficiency in digging the polar flint is still very high, in less than ten days, he dug seventy or eighty pole flints, which almost occupied half of the space inside the fire exorcism, so many extreme flints were stacked together, forming an extremely terrifying high temperature inside the fire exorcism, Qingyang put his fingers inside, even with the protection of the wind and fire order, Qingyang's fingers were burned instantly, which shows how high the temperature inside is.

But think about it, the reason why the temperature of this Yin Wind Extreme Fire Cave is high is because there are earth flint stones and extreme flint stones buried in the cave, and the reason why the temperature in the depths of the earth cave is higher than other places is also because the proportion of extreme flint stones in it is higher, and now a large number of extreme flint stones are stacked together, and the temperature formed must be extremely terrifying, that is, the effect of this fire exorcism refined by Master Shi Han is good enough, otherwise Qingyang really doesn't know how to take these polar flint stones away.

In addition to the extreme flint, in the cave dug by Qingyang, there are also two or three hundred pieces of ground flint stones, which are not of high value and have a lot of quantity, and Qingyang is not even bothered to pick them up. Only those low-level monks, or those who are not capable enough to come to the depths of the cave in the center of the earth, can see this thing.

The lower half of the space inside the fire drive is used to store the polar flint, seventy or eighty pole flints have occupied half of the space, and the upper half is the fire control system refined by Master Shi Han, which is extremely easy to use, Qingyang found a beam of polar fire in the cave and put it in, and the polar fire was stored in the fire-driving gourd, and the pole flint below will continue to provide energy in the future to ensure that this polar fire is not extinguished. to meet the needs of alchemy for heat.

If it is not used frequently, these polar flints are enough to support Qingyang for more than ten years, and if the effect is insufficient in the future, just replace the polar flints inside.

Seeing that there were already seventy or eighty pieces of extreme flint in the fire exorcism, and most of the task this time had been completed, Qingyang decided to focus on the Jinling Iron Mine in the future. It's not that there is no need for Polar Flint anymore, but this matter is not too urgent, there is no need to focus on it anymore, and it is enough to dig by while looking for something else.

Jin Ling Iron Ore is an ore used to refine a refining material Jin Ling Iron, as can be seen from the name, Jin Ling Iron is a metallic refining material, ordinary Jin Ling Iron is not unusual, there are many in the Fang Market of Jiuxian City, and a spirit stone can buy several copies.

In the process of formation, the golden spirit iron ore will form a unique murderous aura every hundred years, and this murderous aura will always be attached to the material, this murderous aura can double the sharpness of the attack magic weapon or spirit weapon, and take advantage of the battle, so the more murderous energy in the golden spirit iron ore, the higher the value.

Ordinary non-murderous gold spirit iron ore, one spirit stone can buy several copies, but this thing is not very useful, and it can also refine some low-level magic weapons used by the monks of the Open Pulse Realm.

The metallic magic weapon is the main kill, and the metal magic weapon containing the murderous aura is even more powerful, so the golden spirit iron containing the murderous energy is particularly sought-after, the golden spirit iron within ten kills is generally used to refine the high-level magic weapons or low-level spiritual weapons used by the qi refining monks, and the golden spirit iron within the hundred kills can be used to refine the high-level spiritual weapons used by the foundation building monks, or the magic weapons used by the Jindan monks.

As for the golden spirit iron above the hundred kills, the magic weapon refined is even more powerful, it is all used to refine the superior magic weapon, even the Jindan monk dreams of it. It's a pity that this kind of thing is too rare, it would be good to have a ten-kill golden spirit iron among the dozens of ordinary golden spirit irons, and there would be no one hundred kills gold spirit iron among the dozens of ten kills gold spirit iron, and the gold spirit iron with more than a hundred kills would be rare to find one among the hundreds of ten kills gold spirit iron.

This cave in the center of the earth is a good gold spirit iron mine, every time the Yin Wind Extreme Fire Cave is opened, there are many monks who come to try their luck, but after so many years, most of the gold spirit iron dug up is below ten kills, and the one that kills one hundred is relatively rare, and the one above the hundred kills is extremely rare, as for the gold spirit iron of a thousand kills, it is even more unheard of.

Of course, even if others dig it up, it is impossible to publicize it with great fanfare, isn't that asking for trouble for yourself? However, this also illustrates the rarity of high-grade spirit mines.

Qingyang was not looking for this golden spirit iron to make a fortune, but the Five Elements magic weapon he was about to refine was still missing a main metallic material, although he also told Master Shi Han to help him pay attention to it before he came, how could the suitable materials be found so easily? He didn't want to replace it with ordinary materials, so he had to find his own way to find good materials.

This Jin Ling Iron is actually a very good material for refining metal magic weapons, of course, Jin Ling Iron below 100 kills is definitely not good, and Qingyang can't look down on that kind of low-level magic weapon material, he hopes to be able to find a piece of Jin Ling Iron Ore with 300 kills or more than 500 kills, so that the metal magic weapon that can be refined can barely be worthy of himself.

As for the higher ones, Qingyang couldn't even think about it, how many years have the monks of the Ancient Wind Continent never gotten such a good Golden Spirit Iron, how could he get such good materials when he first arrived? If there can be a few hundred kills, Qingyang will be content.

In fact, in the past few days, Qingyang has dug up a lot of golden spirit iron ore, but they are all ordinary gold spirit iron, which contains only a dozen pieces of murderous energy, and only one piece of more than ten kills, it is very reluctant to refine the next grade magic weapon, it is almost useless to Qingyang, and the value of all these materials will not exceed a hundred spirit stones, it can be seen how difficult it is to make a good gold spirit iron, if Qingyang wants to get a suitable piece of gold spirit iron, the difficulty is not ordinarily high.

However, this is the depth of eight thousand zhang in the geocentric cave, and few monks can usually come here, maybe they can really get a better golden spirit iron, seven hundred kills, nine hundred kills, or even thousands of kills, for Qingyang, of course, the more murderous energy contained in the golden spirit iron, the better.

Thinking that he had already gathered all the knot pill materials, and he would soon be able to refine the knot jin dan after going out, and even become a jin dan monk, thinking that he had already gathered four kinds of magic weapons with five element attributes, and now only the last one was left, thinking that after he knotted the knot, he could use the magic weapon made of five rare materials to cast the five elements sword array to kill the quartet, qingyang's heart was full of energy, this time he would work harder, and he would have to get the last material together.
