After a total of eight days, Ren Fei finally came out of the cave.After all, the process of sitting here all the time to comprehend the Lingyuan pattern is not only quite boring, but also consumes an extremely long time.Moreover, after so many days, he estimated that the cave hall in the vein had already been excavated, and maybe even the pattern array and array had been laid out, and he still had to go back to see the situation.Now all he thinks about is how to make money, and only by starting his own business first can he have a steady stream of money.If he wants to break through the realm quickly in this year's time, he will definitely need a large number of pills to ensure it.And if you want to increase the speed of the spiritual source pattern, you need to buy a lot of divine arts to learn.These are all things to burn money, and at this moment, money has completely equated with the improvement of his strength.After Ren Fei left the cave, he quickly returned to the mining area."
Uncle Wan Ju, has the cave hall been completed?"
As soon as Ren Fei returned to the mining camp, he saw Ren Wanju."
It's been completed, and Senior Zheng Yuan has taken over the cave hall.He wouldn't let me in, and I don't know what's going on inside!
”Ren Wanju said to Ren Fei.Ren Fei nodded when he heard this, and then walked into the mine, until he came to the newly excavated cave hall deep underground.In the mine not far from the cave hall, there are two Ren family members who guard this place, and no miners are allowed to enter.When the two saw Ren Fei coming, they hurriedly saluted.Ren Fei, along with Zheng Yuan and Li Shuang, were the only people allowed to enter the mine.Passing through the passage of the mine, Ren Fei soon came to a huge cave hall, which was unexpectedly full of pattern spirit patterns.A statue of the array he had seen before was also arranged in the cave hall.The aura of earth fire gathered here, making the temperature of the entire cave hall rise a lot."
Senior Zheng, Li Shuang!"
Ren Fei saw that the two of them were standing in front of a jar array and talking, so he immediately stepped forward to greet the two."
Childe, you're here, the arrangement here has been completed, Senior Zheng said that we can start work at any time!"
Li Shuang rubbed his hands together and looked excited."
Ren Fei, we don't have many gold coupons, only five thousand taels of gold coupons, so let the Ren family send five thousand taels of gold.We are waiting for the gold to be purified, and we don't know how much we will be able to refine in the end!
”Zheng Yuan said to Ren Fei.Ren Fei stepped forward when he heard this, and he also heard a strange noise coming from a few jars.He could feel the aura of the wind and the aura of the fire aura coming from the jar.The fire aura is brought by the fire of the earth, and the high temperature it creates keeps the gold melting.The Wind Aura drives the bottle mechanism in the jar to rotate at high speed, so that the gold solution can be stratified and impurities can be precipitated.The three of them waited in the cave for about an hour, and the noise in the jar gradually subsided.Zheng Yuan asked Li Shuang to open a jar, which was not entirely made of metal, but a special combination of gold and stone.It is resistant to high temperatures and has a certain amount of transparency, allowing people to see the contents clearly.Sure enough, after a centrifuge-like action, the gold solution was separated into seven or eight layers.Pure gold has the highest percentage of delamination, accounting for four-fifths of the bottle, while remaining impurities account for one-fifth.In other words, out of the 5,000 taels of gold here, only 4,000 taels of gold can be used to refine jewelry, and the other 1,000 taels are impurities that can only be discarded.This proportion is not low, and one-fifth of the loss adds a lot of costs.An icy stream of watery aura rose from the bottom of the jar, quickly cooling the solution in the jar and solidifying it back into metal.Li Shuang opened a bottle and took out the cylindrical metal inside.He used a sharp blade specially designed to cut metal to remove several layers of impurities, and the last pure gold part that remained was the purest gold.Moreover, under the powerful centrifugal action, the bubbles in the gold were also completely eliminated, making the purity of these gold extremely amazing, even surpassing the gold refined by Ren Fei himself.The three of them all looked at the purified gold with smiles on their faces at the moment, and Zheng Yuan said: "The purity of these gold is extremely high, Li Shuang and I can cut all of them into the prototype of the jewelry first, and then we can engrave the spirit pattern."
The jewelry you want should be able to be forged with pure gold!
”Zheng Yuan already knew what Ren Fei's business was, and he was also quite interested in it.After all, the ancient clan of the pattern array itself took the road of science and technology, and the invention of this kind of jewelry made him feel the subtlety of it.Being able to use simple materials to cast jewelry similar to the effect of spiritual weapons is also a rather genius creation in his opinion.Ren Fei looked at the gold silently, he thought for a moment, and said: "Senior Zheng, the value of gold is not small, I don't know if we can use the array weapon you made to purify other metals."
The jewelry we cast now is basically used to engrave the water spirit pattern.Although gold is a five-element thing, in fact, we don't need its all-five attributes.To carry the water spirit pattern, in fact, the metal effect of the water attribute should be better.For example, the azurite here is itself a dual-attribute thing of gold and water.If azurite is used to make water-based jewelry, will it be more effective?
And the value of azurite ore is also lower than gold, one tael of gold for five taels of azurite ore should still be possible, if you can use azurite as a raw material, we not only earn more, but also seem to be more convenient.This is where the azurite comes from, so I can collect raw materials on the spot and don't have to exchange gold vouchers for gold. ”Hearing Ren Fei's words, Zheng Yuan touched his chin and said, "Your idea is not bad, but I have to try it to find out."
It just so happens that I've built a furnace over there and I'm helping to smelt the azur ore!
”Zheng Yuan beckoned to Ren Fei, and Ren Fei pushed Zheng Yuan's wheelchair towards another pile of array weapons not far away.Li Shuang has been taking the purified gold from the jar and cutting it to remove the impurities, leaving only the purest part of the gold.Ren Fei pushed Zheng Yuan to the side of the furnace of the azurite mine, the furnace here looked quite simple, and there was no other purpose, only smelting a function.The array here absorbs the power of the earth's fire, raising the temperature in the furnace to a very high level.After the azurite ore is smelted, the metal sinks to the bottom, while the stone carbon slag and other substances are less dense and float on the surface.The impurities on the surface of the furnace will be discharged to the outside of the furnace under the action of the array furnace, and the last thing left is the blue copper ingot that has been smelted and purified.The two waited for a while, and a dark blue copper water flowed out of the bottom of the furnace and gathered into eight small cells.When the lattice was filled, a cloud of water aura rose up, and the cold wind cooled the copper water in the lattice into eight dark blue copper ingots.Ren Fei took out one of the copper ingots, and the two returned to the jar area.Li Shuang had already taken out all the gold that had been purified for the first time, and he had removed all the impurities, and the pure gold had been neatly stacked in a large box.Zheng Yuan commanded Ren Fei and put the copper ingot into a huge container on top of a jar.Here, the ingots are heated by high temperatures, and the cooked copper water flows down each bottle.The bottle then begins to rotate at high speed, layering the copper inside.Another hour passed, and the three of them completed a layering experiment while guarding the jar.When the jar was opened again, Ren Fei directly opened the eye of heaven and forgot about the jar, and immediately showed a look of disappointment on his face."
No, the delamination is layered, but the purified blue copper is not pure enough at all.There are too many impurities in blue copper to be used to refine jewelry!
”Ren Fei looked at the bottle, among the layered blue copper, there were still a lot of different kinds of aura light, obviously the effect of this centrifuge was not strong enough, and it could not completely throw out the impurities in the blue copper.Hearing Ren Fei's words, Zheng Yuan said, "You can see it with your eyes alone!?"
”Ren Fei was stunned for a moment when he heard this, and then hurriedly lied and said: "My master is the master of casting, Qin Wuwu, he taught me a secret technique, and I can roughly see if the purity of the material is enough." ”Hearing Ren Fei's words, Zheng Yuan didn't delve into it, thought about it, and said, "If my separation tank increases the rotation time, it may still be able to separate the remaining impurities, but I just don't know how long it will take?"
