"The system can be purified from ore to lower grade finished products, to medium grade, top grade, and best grade, each gram of purification of the first grade requires ten degrees of energy, the second level consumes 10 degrees of energy, the third level consumes 1,000 degrees of energy, and the fourth level consumes 10,000 degrees of energy, please decide which level of purification to carry out. The detector said coldly.

Shen Fei naturally knew that a sesame-sized silver iron ore particle was one gram as the detector said, and now it was twenty-three, and the top purification was only 230,000 energy degrees.

For such a small energy consumption, Shen Fei didn't care at all, not to mention the millions of energy degrees in his body, even if he didn't have it, he still had four pure yuan beads to replenish, so he waved his hand very heroically and said:

"Directly purify all the silver and iron ore in my hands. ”

As soon as these words came out, Shen Fei immediately felt a warm current surging from his body to his palm, and then the naked eye could see that the twenty-three low-grade silver iron ore particles began to melt into a pool of silver liquid.

As the liquid began to boil, some gray-black impurities slowly floated on the surface, and were directly vaporized after the worst.

After those impurities disappeared completely, the small pool of silver liquid became more silvery bright, and then began to slowly condense into a bead the size of a bean, when this change stopped, this silver was a little dazzling, and at first glance, it was not a bead that felt like silver, and it fell into Shen Fei's palm steaming.

The condensation process of the detector is the time of ten breaths, and the detector spits out a sound:

"After purification, 255,300 energy degrees are consumed. And there was no more silence.

Shen Fei blinked his eyes and muttered:

"Didn't you say that you only need 10,000 degrees of energy for the best purification?

But because of the lack of energy, he didn't care, just weighed the bead in his hand, which weighed a penny.

Just after looking at this bead, Shen Fei's face immediately changed:

"Wow! The low-grade silver iron ore just now weighed two or three taels, and now it has become a penny in terms of weight. Didn't I die?"

As if he couldn't get used to seeing Shen Fei's idiot, Shen Yanyun jumped out and shouted:

"Xiao Fei, you stupid! The detector condenses an item of the best level, which is a hundred times the value of the high-grade item, and the high-grade item is a hundred times that of the medium-grade item, and the middle-grade item is a hundred times that of the low-grade item. You calculate how much low-grade silver iron ore is equivalent to this heavy amount of silver iron ore. ”

"One hundred of one hundred is ten thousand, one hundred of ten thousand is one million, how many catties can this million dollars be exchanged for?" Shen Fei was counting with his fingers, but unfortunately he didn't know how to learn mathematics, and he couldn't help but look confused.

"Master. One catty is equal to ten taels and one hundred dollars, so master, your bead is equal to 10,000 catties of low-grade silver and iron ore. "This time, it was Zhi Brain who jumped out to answer, and I don't know if Shen Yanyun disdained to explain or what.

"10,000 catties of low-grade silver iron ore, is it impossible, is it? such a bean-sized thing is actually equal to 10,000 catties of low-grade silver iron ore? Doesn't this mean that as long as there are ten such things, my punishment will be completed?" Shen Fei shouted in surprise with wide eyes.

"That's true, and master, why have you been mining alone? Those thirty flame girls can completely help you, they will not consume the power of the faith of the world realm now, but only the power of the flame faith. You must know that the Flame Faith Bead has now become eight, and it can't be consumed at all. Zhi Brain said again.

Shen Fei slapped himself hard. Some yelled angrily:

"Damn, why didn't you come out to help? You are free to enter and exit my sea of knowledge, are you deliberately watching me out of trouble?"

Thirty flame women immediately appeared, their fiery red hair. The bottom of the well was lit up at once, and they all looked anxious and chirping around Shen Fei, nervous for a while, and they couldn't use human language.

But fortunately, Shen Fei can understand. So the anger quickly calmed down and waved his hand:

"Okay, you thought it was because I wanted to practice so I didn't come out to help, but it was my fault. Well, now help me mine, get more silver and iron ore out, and we can get out of here early, and then go outside and enjoy the blessings. ”

The flame girls immediately chirped excitedly, and then directly used the flames to conjure tools like hoes, and dug directly to the bottom of the well.

For doing things with such beauties, Shen Fei not only did not have any pity, but led them to climb to the mouth of the well and dig this well down, as for what to do with the wasteland? Of course, it is directly filled in the well, how can this well be filled with a million catties of wasteland.

With the help of these thirty flame women who were still digging happily, Shen Fei naturally sat on the side and began to refine silver and iron ore for the first time.

When that deep well turned into a depression, Shen Fei not only refined the silver and iron ore dug by himself and the Flame Girl, but also asked the detector to purify all these inferior silver and iron ore into the best silver and iron ore.

Looking at the silver-white metal ball as big as an adult's fist in his hand, Shen Fei was very surprised.

You must know that this superb silver iron ore ball weighs twenty catties, and in order to refine it, Shen Fei not only used up the millions of energy degrees in his body, but also filled it with a pure vitality bead.

The loss is huge, but the results are also huge, this superb silver iron ore alone is equal to 20 million catties of lower grade silver iron ore, but the most important thing is only to take 400 catties of lower grade silver iron ore to refine!

With such a comparison, Shen Fei was pleasantly surprised to find that the purification function of the detector was simply against the sky, because according to the refining method of the current world, only one hundred catties of ordinary iron ore could refine one catty of refined iron.

Even, some of the higher metals that Shen Fei didn't understand needed a larger proportion to refine, where would it be like a detector, continuously improving the third-level purity was actually twenty to one, so wouldn't it be developed to be a metal purifier by himself?

Similarly, Shen Fei was also shocked, this was only after he purified it once, he handed it over to the detector for three purifications, if he directly let the detector purify it four times, would it pull this ratio down?

Thinking of this, Shen Fei hurriedly found a piece of silver and iron ore that the flame girl had just sent, and first weighed it, this ore weighed ten catties, and if he used his own flame to refine it, he could get one or two of low-grade silver and iron ore, that is, a hundred to one consumption.

Well, as long as you know how much low-grade silver and iron ore the detector can extract from this ore, you can know whether it is cost-effective to hand it over to the detector directly for refining.

As soon as he thought of it, Shen Fei hurriedly ordered the detector:

"Refining the silver and iron ore in this ore, first refining it into the next grade silver iron ore will stop. ”

Without saying a word, the detector directly borrowed Shen Fei's palm and began to refine this ore.

The speed of the detector was much faster than Shen Fei's, and in an instant, he saw that the iron ore turned into molten iron and dripped down, and only the trace of silver iron ore remained in the palm of his hand.

In just a few breaths, a silver bead the size of a small plum appeared in front of Shen Fei, and the detector said very coolly:

"It consumes 2,500 degrees of energy. ”

"Uh, two thousand five hundred degrees of energy, each gram consumes ten degrees of energy, that is, this bead has two hundred and fifty grams, that is, five taels?" muttered to the back, Shen Fei had already roared loudly.

When I thought that I was refining only one tael of low-grade silver and iron ore, but the detector refining was five taels of low-grade silver and iron ore. Wow! That's a five-fold gap, that is to say, if you handed over all the ores to the detector for refining before, then you don't have 400 catties of low-grade silver and iron ore, but 2,000 catties of low-grade silver and iron ore?

How many low-grade silver and iron ore can be exchanged for 100 catties of low-grade silver and iron ore? 100 million catties of low-grade silver and iron ore can be exchanged for 100 catties of low-grade spirit stones, which is enough to exchange for 10 billion catties of low-grade spirit stones. Whoa, Shen Fei was so depressed that he wanted to slap himself.

"Master, do you still want to dig?" The flame girl woke up Shen Fei, who was extremely depressed, Shen Fei stood up and waved his hand, shouting:

"Dig! Don't dig for anything!"

But as soon as he finished saying this, Shen Fei immediately waved his hand again and shouted:

"Wait!" The flame women, who were about to dig again with their hoes, suddenly stopped and looked at him.

Shen Fei paced back and forth, clapping his palms:

"Wow! Wouldn't it be easy to get the silver iron ore and those miners to exchange ore for ore?"

"Master, this method is good, but at what price are you going to exchange for ore?" Zhi Brain said again, obviously still occupying the common body.

"At what price? I personally condensed ten catties of ore for one or two lower grade silver and iron ore, and those miners estimated that they could not reach the condensation exchange rate like mine, but, well, what is the exchange rate between the ore in the palace and the inferior silver and iron ore? I really don't believe that these miners will smelt the finished silver and iron ore like me and turn it in. By the way, there is an introduction in the jade slip of the refining method. Shen Fei hurriedly took out the jade slip.

Looking inside, Shen Fei smacked his lips in amazement:

"Wow! Ten catties of ore for the size of a bean, that is, one gram of weight of low-grade silver and iron? This ore alliance and business alliance are really black-hearted and black-hearted!"

Shen Fei had time to shock the other party's black heart, but he was stunned to find:

"What? Silver iron? Not silver iron ore? That is, what is refined is the finished silver iron, and it is no longer a mine? Whoa! I have been shouting about refining silver iron ore just now. Fortunately, the others don't know what to do, otherwise they would be disgraced. ”

Shen Fei was a little embarrassed to put away the jade slip, and then took out the five taels of inferior silver and iron, and went to exchange ore with the miners. Naturally, you can't exchange such a large piece, you have to cut it into small particles.

Shen Fei first took out the dagger to cut the bead, but the dagger collapsed, and the bead was unharmed, not even a single knife mark existed. (To be continued.) )
