All the way towards the Jiuqu River, everyone walked out of the mountain range and came to the grassland, and when they arrived at the river, there was no sense.

"Brother Yan, it seems that it is impossible for us to drill wells by the river, there is no more here. Fang Fengbao took a turn by the river and sighed helplessly. "The nearest distance is three miles away, so let's just divert water. ”

Fang Yan looked at the direction of the river, corresponded to the oil veins, found the right position and marked: "Next, I have to rely on your help to prospect, there are a lot of precious ores in the black water and white mountains, I lack materials in my hands, and the detectors in your hands will be brought." ”

Retracting the probe, Fang Yan modified it slightly, and then restored it to the ore vein detector and handed it over to everyone again.

The bald man could return at any time, and the crowd had little time, so they returned to the mountains and scattered in search of mineral deposits, and soon made discoveries.

Just on the periphery of the Black Water and White Mountain, all kinds of precious mineral deposits can be easily found, and you can get good quality ores just by digging casually.

In the mountains and forests, a clearing was cleared, and a three-zhang high refining furnace was located in the center of the clearing, and the surrounding ground was carved with mysterious formations, and spirit stones were all over the nodes.

Fang Yan sat in front of the refining furnace, opened the furnace to refine the ore, and Lin Feng and the four of them kept carrying all kinds of excavated ores.

"Lingshi vein! made a fortune, made a fortune. Fang Fengbao suddenly exclaimed, attracting the attention of Lin Feng and everyone.

Holding a half-cubic spirit stone out of the hole, Fang Fengbao had wind under his feet, running like a rabbit.

Fang Yan stepped forward, took the spirit stone and carefully examined it: "The three-grade spirit stone, there are not many impurities, and the quality is good. ”

Fang Fengbao laughed and said: "That's a spirit stone vein, what I dug up here is only a piece on the periphery, there are three grades, and there must be four or five grade spirit stones in it, we are developed." ”

A spirit stone vein is the same as the earth's gold mine, and the periphery of this spirit stone vein can dig out a third-grade spirit stone, and there must be a fourth-grade spirit stone inside, and the core may also appear a fifth-grade spirit stone.

The money circulating on the market, in the hands of ordinary people, is generally the worst spirit stone without grade, that is the leftovers, which belongs to the denomination of copper, and the better one is the first-grade spirit stone, which is very circulating, and the three hundred spirit stones in the original Fangyan exam are also first-grade spirit stones.

The quality of the spirit stone is judged by the amount of aura, and the first-grade spirit stone will also become the worst unqualified spirit stone because of the loss of aura, and it is normal to drop the grade, just like the gold coins in circulation in ancient times, there are always some wear and tear or greedy people cut the lower corners and reduce the amount, the principle is similar.

Generally speaking, the difference between each grade is ten times the difference, and the three-grade spirit stone that Fang Fengbao dug up, as long as it undergoes special processing, can almost make dozens of third-grade spirit stones, a vein, and the spirit stone contained in it, the price is naturally sky-high.

"It's a pity that we can't take it away in Heishui and White Mountain. Senior Sister Hu's words instantly knocked the ecstatic Fang Fengbao into the abyss, and the expression on her face instantly became like a dead father.

"Don't, my spirit stone, why did God ...... me like this" Fang Fengbao knelt on the ground and looked up to the sky and cried.

Fang Yan said helplessly: "Okay, okay, don't cry and mourn, the spirit stone can't be taken away, we can't take it away in another way." ”

Fang Fengbao stopped instantly, stood up with a look of surprise and said, "Brother Yan, quick, help me upgrade and perfect the dragon scale armor, I want to improve the dragon scale armor to the peak state." ”

Fang Fengbao's words woke up Feng Yu and the others in an instant, and the spirit stone could not be taken away, but it could be perfected with the help of this spirit stone vein.

Fang Yan hurriedly stopped everyone's hot gaze: "Don't worry about the matter of the spirit stone for now, Fengbao, you continue to dig, the rest of you will go to mine for me, while the bald man has not come back, we must finish the matter first, don't pick up the sesame seeds and lose the watermelon." ”

Only then did everyone calm down and disperse to continue mining.

With the spirit stone, Fang Yan's refining ore is also much simpler and easier, directly decompose the spirit stone dug out by Fang Fengbao and place it in the formation, first strengthen the power of the formation, and extract the spiritual power of the mountain range.

With spirit stones and enough ores, Fang Yan was also able to put his ideas into practice, combining the cognitions and ideas of his previous life, and assembling four sets of mining machines with the method of refining, with spirit stones as the power core, and human operation.

After handing over to the four people, the speed of mining has also increased several times, and as long as this machine has enough spirit stone power support, it can continue to run non-stop until it is scrapped, with a spirit stone vein to support, the power source is not a problem at all.

A large number of ores and spirit stones were sent back, and were thrown into the refining furnace by Fang Yan for refining, assisted by the positive and negative yin and yang gossip arrays, and the refining furnace was located in the center of the array, and with the continuous refining of materials, the flames in the array were blazing, and the refining furnace was also wrapped in it.

Fang Yan was not only refining materials, but also taking advantage of this opportunity to refine the refining furnace, as a refiner, not having a good refining furnace was always a trouble. It's better to take the opportunity to refine a good one, and you can use it in the future.

The ore that has been piled up into a mountain, after a refining, the loss will be about sixty percent, the second refining will be lost, and after three refining, the obtained will be one or two percent.

After accumulating in two days, the refining materials were also piled up, and seeing that the materials were almost enough, Fang Yan put them back into the refining furnace and began to refine them.

After shaping and combining, after perfecting it step by step, it finally turned into a large pile of parts, Fang Yan burned it into a rune formation to carve inscriptions, and finally reassembled it to become a huge mechanical worm 100 meters long, which looked very similar to a sandworm.

"It's a pity that the refining furnace is too scummy, and sooner or later I will have to build a refining furnace like the legendary Qiankun Ding. "The refining furnace is too small to fit the combined mechanical worms, and the final refining step can't be helped with the help of the refining furnace.

Flipping his hand and taking out an inscription metal ball from the storage ring, Fang Yan opened it, and a fist-sized earthy yellow bead lay inside, the bead emitted a faint light, and the aura contained in it was terrifying.

"What baby?" Fang Fengbao and Senior Sister Hu all returned, all attracted by the aura of this bead.

"Sandworm's Neidan, Brother Yan, you lied to me. Fang Fengbao rushed forward with an arrow step, and reached out to grab the beads in the metal ball.

Fang Yan turned around and hit his shoulder, knocking Fang Fengbao to a stagger.

"Fuss, if you don't want to die, don't fight its idea. Fang Yan said as he walked over to the mechanical sandworm, put it in the body behind his head, and assembled the last few parts to make the mechanical sandworm complete.

"Loser, loser! Brother Yan, I beg you, don't do this, okay, don't. Fang Fengbao looked at this scene as if his father and mother had died.

Fang Yan grabbed Fang Fengbao, pulled him out of the magic circle, and immediately urged the formation, the spiritual light of the formation on the ground flowed, the spirit stone flickered with light, and the mechanical sandworm coiled in the center burned with raging flames.

The aura of heaven and earth swept in, forming a whirlwind, pouring into the large array, and a translucent enchantment visible to the naked eye appeared in the array, enveloping the mechanical sandworm, and the endless aura poured into it, completing the last step of refining.

"It's over, it's over, my ninth-level demon beast Neidan, Brother Yan, do you know what you destroyed?" Fang Fengbao wanted to cry without tears. "That's a mountain of spirit stones, more valuable than the spirit stone vein I found. ”

Senior Sister Hu also stepped forward with a little pity and said, "You are really willing." ”

Lin Feng and Feng Yu both showed admiring eyes, a ninth-level demon beast inner pill would be equivalent to an artifact-like existence, and whoever got it would consider absorbing and refining it themselves to improve their strength. There is a ninth-level demon beast Neidan, and it is a waste to achieve the Martial King, and the Martial Emperor is only the most basic condition, even if it is the Martial Emperor, it is not impossible.

"The husband is not guilty, but he is guilty. It is impossible for any of us to absorb and refine this inner pill, we can only use it to refine the pill, then we must go to the alchemist, if anyone knows about its existence, what do you think it will do?" Fang Yan said without further words, cutting the spirit stones accumulated next to him and adding them to the formation.

Fang Fengbao calmed down, sighed helplessly, and said, "Brother Yan, even if that's the case, what's the use of you using it to refine weapons and make such a big guy?"

Feng Yu looked at the mechanical sandworm in the array and said, "It looks very similar to the sandworm, you don't want to use it to drill wells, right?"

Fang Yan smiled: "You all underestimate it, what I need is a super excavator, with which we can dig out the entire spirit stone vein." ”

Fang Fengbao's eyes lit up: "So powerful?"

"You'll know when the time comes, although the material of this big guy is a little worse, the efficiency is definitely not bad. Fang Yan said to everyone. "The spirit stone is gone, hurry up and dig again, there is not enough supply of spirit stones, my refining weapon may fail." ”

After everyone heard this, they hurriedly went to dig the spirit stone, if they really failed, everyone would be distressed, after all, it was not a ninth-level demon beast Neidan who was invested.

The four of them entered the spirit stone vein together, Fang Fengbao was in charge of transportation, and the other three kept digging spirit stones.

Time passed little by little, and the spirit stones that were transported were sent into the large array by Fang Yan one by one, supplying the large array to operate at full strength, completely locking the spiritual energy in the array and preventing it from escaping.

The problem of not having a refining furnace is so troublesome, it can't lock the aura, and the final warming process of the refining device is extremely troublesome, and the formation must lock the internal aura, and it can only run to the limit, and there can be no mistakes, otherwise it will lead to the leakage of the aura and the error.

The last step of the refining device is actually like the last step of cooking rice in a high-pressure oven, a large amount of spiritual energy is constantly sent into the interior, so that the spiritual pressure increases little by little, but this spiritual energy must be locked, once it is deflated, the spiritual pressure is insufficient, and the quality of the magic weapon will deteriorate, and it may even be scrapped.

Without the support of a spirit stone vein, Fang Yan would not dare to play such a big one.
