After the 'Ice Vein Ore Pith' was piled up in the small courtyard, the high temperature around it dropped a lot. With such a small piece of ore, the effect is much better than air conditioning.

The 'Ice Vein Marrow', as the name suggests, only exists in some extremely cold places.

There are many strange planets of all kinds in the universe, and there are also some extremely cold planets that are wrapped in thick ice all year round. The 'ice vein marrow', mostly exists in the ice rock or ocean at a depth of 10,000 meters, under the interaction of huge pressure and extreme cold, the essence of water is formed, and under normal circumstances, thousands of miles of icebergs, at most can only form a fist-sized 'ice vein marrow'.

Now, just the craftsmen of their group have been divided into a large stack. It can be seen how wealthy the Qin family's employer is this time.

To refine the 'Ice Vein Mineral Marrow', even the true fire in the body of the Earth Immortal cannot be done, and the only way to do it is to rely on the True Fire in the body of the Heavenly Immortal.

As a well-known refining instrument embryo family, the Qin family can naturally smelt the 'Ice Vein Mineral Marrow', because the 'Burning Sun Star' where the Qin family is located is very special, and the Qin family's special smelting method relies on the earth's core flame of the 'Burning Sun Star'.

Although relying on the 'Burning Sun Star's geocentric flames, it is possible to successfully smelt the 'Ice Vein Mineral Marrow'.

But after all, the fire in the center of the earth is different from the true fire in the body of a cultivator.

The temperature of the flame is more unstable, and the form is more violent, and when it is retracted, it is even more impossible to be as free as the real fire in the body.

Therefore, the whole process of smelting the 'Ice Vein Ore Pith' with the fire in the center of the earth must be very slow.

Because of Qin Liufeng's attention, this time, the entire smelting process of this group of craftsmen. It is supervised by the third person himself.

The stout body of the third child is half-lying on his stomach. His face was pressed in front of the flames in the center of the earth, and his hands carefully fine-tuned the formation. This allows the flame to come out of the furnace to the optimal temperature.

The smelting method of the 'Ice Vein Mineral Marrow', Du Laosan didn't know before, this time Qin Liufeng specially taught the smelting method, so whether the smelting can be successful, Du Laosan also has no bottom in his heart.

After more than an hour of fine-tuning, finally, Du Laosan felt that the temperature of the flame in the furnace was almost the same, so he turned around and shouted: "Sentai." Get the marrow!"

Sentai is the second highest level among the more than 20 craftsmen.

Hearing Du Laosan's order, Sentai immediately used the mining tongs to pick up a small piece of 'Ice Vein Ore Marrow', and then gently placed it above the flame of the furnace eye.

This small section of the 'Ice Vein Mineral Pith' is used for experiments, in order to accumulate experience and better smelt the rest of the 'Ice Vein Mineral Pith'.

The marrow did not react in the furnace, but Du Laosan's patience was very good, and he kept lying on his stomach. Take a closer look at the smelting of the 'Ice Vein Pith'. His observations are not only comprehensively wrapped in the field, but also seen with the naked eye.

Although, within the field. It's all about happening. However, in the actual smelting process, many states and reactions of the ore must be observed with both eyes. Even sniffing and hearing can really judge the timing.

Otherwise. Miss the best time, then the purity and quality of the ore, etc. It's going to be a big discount.

According to the smelting method provided by Qin Liufeng, the 'Ice Vein Mineral Pith' needs to be burned for three full days in the 6,700-degree geocentric fire, and after three days, it will be smelted into a liquid state.

However, at the moment of becoming liquid, the flame must be abruptly withdrawn, otherwise, the 'Ice Vein Ore Pith' will be directly vaporized in the continuous high temperature, which will not only be a waste of hard work, but also a waste of a precious ore.

In this way, Du Laosan, Sentai and the other three craftsmen took turns to take care of it for three days, always paying attention to the smelting of the 'Ice Vein Ore Marrow'.

After all, if you keep letting a person observe in the flames at such a close distance, anyone's eyes will not be able to stand it.

Finally, three days passed, and the first 'Ice Vein Ore Marrow' used for testing was also slowly melted into liquid under the gaze of Du Laosan and others.

Before they could breathe a sigh of relief, the liquid formed by the melting of the 'Ice Vein Mineral Marrow' actually directly rose up a puff of pale blue smoke, which quickly vaporized and escaped from the vent of the smelting furnace.

"Quickly withdraw from the fire in the center of the earth!" shouted the three of them.

The rest of the people hurriedly did so, instantly changing the formation of the furnace eye, sealing the flames in the furnace eye.

The flame is sealed, and the temperature in the furnace plummets.

The 'Ice Vein Ore Marrow' used for the experiment was only half liquefied, and the remaining ones, because the temperature was not enough, had to start smelting again. Of those that have been liquefied, a small half have escaped because of the high temperature.

This experiment ended in this unsuccessful way.

For three whole days, not even a single 'Ice Vein Ore Marrow' was successfully smelted, and a small half of it was wasted. The smelting difficulty of this 'Ice Vein Ore Marrow' is too great, right!?

For a while, Du Laosan, Sentai and others all frowned, feeling huge pressure.

More than 20 people, under the convening of the third child, discussed how to deal with it. Everyone has said a word, and there are many methods, but most of them are only imaginative, and it is estimated that after they are really adopted, the probability of success is very low. A large group of experienced craftsmen were stumped in front of such a unique ore as the 'Ice Vein Essence'.

At this moment, a person said beside him: "To smelt the 'Ice Vein Mineral Pith', it is actually very simple, in fact, give you some time, you can also think of it, but at present, I am entangled in the characteristics of the 'Ice Vein Mineral Pith', and I will ignore it for the time being." ”

Everyone looked, but saw that it was Dumb who walked out of the room.

"Dumb, if there is any way you can tell me quickly, we are all going to be anxious to death by the current situation. Du Laosan saw the savior and hurriedly ran over.

Dumb smiled lightly, and then said the solution.

His solution was very simple, which was to add another formation to the smelting furnace.

Originally, in the Qin family's smelting furnace, there was only one formation, and this formation could control the temperature of the earth's core flame, and it could also isolate the temperature instantly. And Dumb's solution is to set up a new one of the same formations next to this formation.

The first formation is used to control the right temperature, and then it takes three days to smelt the 'Ice Vein Marrow' into liquid. Once the 'Ice Vein Marrow' is liquid. Immediately, someone would wrap these liquids in the realm and quickly move them to the range covered by the second formation. The temperature in the second formation is a bit lower than in the first formation. Therefore, when the liquid is moved in, there will be no vaporization escape.

But. To control this process, you need at least two people who cooperate with each other to complete it.

When everyone heard this, they immediately felt that this method was indeed simple and easy to implement.

Du Laosan was even more happy to slap each other's fists, but he still had doubts in his heart.

"Lord Dumb, the method you said is indeed a first-class good method, but use the liquid of the field to wrap the 'Ice Vein Mineral Marrow', and then move to the second formation, this process. I'm afraid that the energy in the body of the person who controls it will consume a huge amount. ”

Du Laosan's concern is not unfounded.

The realm of cultivators also needs energy to maintain, and the high temperature of the furnace eye will aggravate the consumption of energy, not to mention, the formation that controls the temperature in the furnace also needs energy to maintain. It is also necessary to wrap the field to move the liquid in high temperatures. These actions require strong energy support to complete.

It's like taking an icicle and going to the fire to stir something, being scorched by the flames. The icicles themselves will melt and consume.

Dumb nodded when he heard this: "So, everyone has to take turns to contribute, and I will also help." I believe that everyone will work together. Be careful, and there will be nothing wrong with it. ”

The people took some more time to deliberate. I felt that this was indeed the best way I could think of at the moment, so I nodded and agreed one by one.

Subsequently. The smelting of the 'Ice Vein Marrow' has officially begun.

Du Laosan chose a good craftsman to cooperate with him and began to operate the first furnace, while Dumb kept watching, and occasionally reminded him.

"The underside of the 'Ice Vein Pith' will soon liquefy. ”

"The first formation maintains the temperature, the second formation is a little hotter, and now the control field moves the liquid over. ”

"Shan Li, what are you still doing in a daze, go and get Wen Yu's bottle to receive the essence of the 'Ice Vein Mineral Marrow'. ”

These are all dumb reminders to them.

Before, Dumb's reminder was only occasional, but now, seeing that the 'Ice Vein Mineral Pith' has been smelted and liquefied little by little, Dumb's reminder has become frequent.

It took two full hours for a piece of 'Ice Vein Marrow', which was as large as masonry, to completely smelt into liquid.

A large piece of the liquid smelted by the 'Ice Vein Mineral Pith' just filled a small warm jade bottle.

The first furnace was successful, and the nervous mood of the third-class craftsmen relaxed at this moment, wiped the beads of sweat on his forehead, and turned around and gave Dumb a bear hug.

"Brother, thanks to you this time!!"

Hugged by Du Laosan, who was coaxed by the smell of sweat, Dumb was not dirty, just smiled, looking like he was really happy for Du Laosan: "Okay, Du Laosan, let's get ready to start the next furnace, finish it early, and make the difference early." ”

Du Lao San nodded heavily, turned to the craftsmen and shouted, "Brothers, cheer me up, everyone continue." ”

The 'Ice Vein Ore Marrow' that they need to refine this time has a total of 150,000 catties, which is fifteen pieces the size of bricks.

Once the furnace is successful, it is smelted into 10,000 catties of marrow. With such a heavy object, ordinary cultivators or mortals would not even be able to pick it up.

Fortunately, most of these craftsmen are good, and in the past sixty days, including the previous test, they have smelted a total of sixteen furnaces.

However, in the process of refining, there were still some small episodes. Sentai didn't know if he was too nervous or too tired, when he presided over the refining of one of the furnaces, there was a mistake in the link of wrapping the liquid in the field, so that nearly one-tenth of the 'ice vein marrow' vaporized and escaped, but fortunately, Dumb made a timely move later, so as not to waste more.

It was originally scheduled to be completed in three months, but it only took them more than two months to complete it, and the success rate and loss rate were also satisfactory.

Someone was ordered to report it, and immediately a master of the Qin family in the early stage of the Earth Immortal led a group of immortal guards to the small courtyard and took away the essence of the 'Ice Vein Mineral Marrow' that had been refined.

After sending off the guards who had come to fetch the essence, the craftsmen finally relaxed, and they surrounded Dumb, the greatest hero, and threw him into the air and caught him, cheering in celebration. Then, Du Lao Sansheng gave an order, and everyone ate and drank for three days and three nights before resting drunk in the courtyard.

For more than two months, everyone was almost tired. At the moment, there is no pressure, and naturally I sleep very comfortably one by one.

These stout men. I don't usually pay much attention to the image. Everyone was drunk at the moment, and after a while, they snored like thunder. It's like a strange piece of music.

Dumb smiled at the tired people on the ground, and then came to the room alone and cultivated with peace of mind.

Du Laosan and the craftsmen slept for two days and three nights, and when they woke up, it was already the morning of the fourth day.

This mission was completed quickly and well, and for most of the remaining half a month, everyone was on vacation. So, all the craftsmen greeted the Qin family and went out to play in the city on the Burning Sun Star. By the way, it's good to buy some things back.

As the craftsman and subordinate of the Qin family, he originally had the opportunity to take a leave every year, but this time he completed the task ahead of schedule, so it was an extra holiday, and everyone was naturally interested.

The third child asked Dumb to go out, but Dumb refused.

When leaving, Du Laosan couldn't help but shake his head, and sighed secretly that Dumb was really an idiot, and he didn't even go out to play. He also hid in his room wholeheartedly to retreat. But thinking that although the other party's name is Dumb, his strength is stronger than himself, and his knowledge is wider than his own, so he was relieved.

God rewards diligence. It still makes a lot of sense.

When everyone went out, Dumb rarely had more than half a month of cultivation time.

The craftsmen are also deliberately dumb and pure, under the leadership of the third child. As soon as the half-month vacation was over, they went to the steward's room together. I also took the vacation of only one month this year.

Dumb is ruthless enough, and no one bothered. He didn't even leave the door of the room at all, and Meimei practiced for more than a month, and it wasn't until everyone returned to the small courtyard after the holiday that he was reluctant to end his cultivation.

"Dumb-sama, you haven't had another breakthrough after being in retreat for so long, right?" a late-stage Dacheng craftsman smiled and joked with him as he passed by.

The third man next to him laughed and scolded: "Shan Chongfei, what nonsense are you kid talking about." Like the realm of Lord Dumb, retreat cultivation can easily take hundreds of thousands of years, and it has only been less than two months, so how can it be so easy to break through. ”

I don't want to, but Dumb nodded seriously: "It's a little bit of improvement, but it's a bottleneck." ”

Originally, the craftsman also asked casually, but he didn't expect Dumb to admit it, and all the craftsmen came around.

"Dumb man, have you really made a breakthrough?"

"Bottleneck, doesn't that mean that you will soon become more powerful, Lord Dumb?"

"By the way, Brother Sentai, I only know that Lord Dumb is an immortal, but what is the state of his cultivation now? Is it the late stage of mortal immortals, or the early stage of golden immortals?"

Everyone was talking about it, surrounding Dumb.

It seems that Dumb's progress is their progress, and they are all excited and sincerely happy.

Looking at these rough men, Dumb's heart was slightly hot, and he felt a trace of inexplicable emotion.

When he said that his cultivation should be around the late stage of the Golden Immortal, everyone was in an uproar.

No one thought that this seemingly young immortal would be such a strong master.

But surprise is surprise, worship is worship, Dumb is still the same Dumb before, and he still likes to giggle with them without distinguishing from each other.

When the craftsman returned from his vacation, the work in the small courtyard naturally began again.

In the fifth month after the 'Ice Vein Mineral Pith', after everyone had gradually forgotten about the matter of smelting the 'Ice Vein Mineral Pith', suddenly another attendant of the Qin family came to inform Du Laosan, saying that they had completed the task of smelting the 'Ice Vein Mineral Pith' last time, not only the fastest completion time, but also the best smelting quality, in order to reflect the Qin family's family style of rewarding meritorious service, Lord Qin Liufeng wanted to personally reward all the craftsmen.

Du Laosan and the others were naturally very happy when they heard this, and ordered everyone to clean up their appearance, and then waited for Lord Qin Liufeng to arrive in the courtyard.

After some waiting, the Earth Immortal Qin Liufeng led several immortal attendants to finally arrive.

"Who is the chief craftsman here?" Although Qin Liufeng was still majestic this time, there was a smile in his eyes, and he slowly swept over everyone present.

Du Laosan hurriedly stepped forward, bowed down and said, "It's the villain Du Laosan." ”

Qin Liufeng smiled and bowed: "Dulaosan, you have led your subordinates to smelt the 'Ice Vein Mineral Marrow' this time, and according to the order of the head of the family, you will be rewarded with 10 medium-grade immortal sound stones." ”

"Thank you for the gift of the head of the family, Lord Xie Liufeng!" The three elders were overjoyed, and carefully took the spar in Qin Liufeng's hand.

Qin Liufeng looked around at the rest of the craftsmen again: "Everyone obeys the dispatch of the chief craftsman, completes the task excellently, and all of them are meritorious, and each person is specially rewarded with 3 medium-grade immortal sound stones." ”

"Thank you for the gift of the head of the family, Lord Xie Liufeng!"

The craftsmen also bowed down to thank them, and then stepped forward in turn to receive their rewards.

After everyone received the reward, Du Laosan specially stepped forward to report: "My lord, this time we were able to complete the task so well, in addition to everyone's efforts, the most important thing is to get the assistance of another adult. ”

Du Laosan is trying to help Dumb beg for rewards, in the minds of this simple man, he has long regarded Dumb as his own.

What's more, in the process of smelting the 'Ice Vein Essence' this time, Dumb's role is indeed crucial, and Du Laosan doesn't want to see everyone rewarded, but Dumb, the biggest hero, has been ignored.

But where did he know that Dumb didn't want to be in the limelight at all. Du Laosan's report for making such an assertion is actually a kind of trouble.

"Oh~ another adult's help? Qin Liufeng seemed to be a little interested.

Du Laosan responded, and immediately explained who the dumb was, and how to help them successfully smelt and complete the task of 'Ice Vein Ore Marrow'.

"Using the method of one furnace and two formations to solve the problem of the smelting temperature of the 'Ice Vein Ore Marrow' is really simple and ingenious!" Qin Liufeng is also an expert in refining, so he naturally knows that this method is ingenious as soon as he hears it.

"Sister Yu'er's personal attendant, there is such a wonderful person?" Qin Liufeng sighed secretly, and hurriedly turned his head and asked, "What about this dumb person?"

Du Laosan said on the side: "Back to my lord, this year, Dumb has stayed in the small courtyard and never went out. Only tonight, Miss Yu'er ordered someone to summon him, and he went to Miss Yu'er's place as ordered. Therefore, he is not there at the moment. ”

Coincidentally, the day when Qin Liufeng came to reward the craftsmen happened to be the day when Qin Yu confined Dumb in the small courtyard for a year.

Under the reminder of the personal maid Xiaocui, Qin Yu finally remembered that he still had such a subordinate as Dumb, so he asked Xiaocui to call Dumb to meet him.

"Well, Du Laosan, I hope you will do a good job, do a good job, and the Qin family will naturally not treat you badly. Qin Liufeng casually said a few polite words and left the small courtyard.

Flying in the air, a smile appeared on his grim face. Speaking of which, I haven't been to see Cousin Qin Yu for a while, but now that I'm in the past, I happened to meet this strange person named Dumb. ”

With a plan in his heart, Qin Liufeng identified the direction and flew directly through the air like an arrow in the direction of the Qin family. (To be continued.) )
