After the ice vein marrow was piled up in the small courtyard, the surrounding high temperature dropped a lot.
With such a small piece of ore, the effect is much better than air conditioning.
Ice Vein Mineral Marrow, as the name suggests, can only exist in some extremely cold places.
There are many strange planets in the universe, and there are also some extremely cold planets that are wrapped under thick layers of ice all year round.
Most of the ice vein mineral marrow exists in ice rocks or oceans at a depth of 10,000 meters.
Under the interaction of huge pressure and extreme cold, the essence of water is formed.
Under normal circumstances, the most amount of water essence can be found in icebergs thousands of miles away.
Only fist-sized ice vein marrow can be formed.
Now, just the craftsmen in Du Laosan's group were given a large pile.
This shows how wealthy the Qin family's employer is this time.
To refine the ice vein marrow, not even the real fire in the earthly immortal's body can do it, only the real fire in the heavenly immortal's body can be used.
As a well-known family for refining artifacts, the Qin family can naturally smelt ice vein marrow, because the sun-burning star where the Qin family is located is very special, and the Qin family’s special smelting method relies on the The fire in the center of the earth of Sunburn Star.
Although it is possible to successfully smelt the ice vein marrow by relying on the inner fire of Sunburn Star.
But after all, the fire in the center of the earth is different from the real fire in a cultivator's body.
The temperature of the fire in the center of the earth is more unstable, and its shape is more violent.
When it is retracted and released, it is even less likely to be as free as the real fire in the body.
Therefore, the entire process of using the earth's core flames to smelt ice vein marrow must be very slow.
Because of Qin Liufeng's attention, this time, the entire smelting process of this group of craftsmen was personally supervised by Du Laosan.
Du Laosan's thick body was half lying on his stomach, with his face in front of the fire in the center of the earth.
He carefully fine-tuned the formation in his hands so that the flames coming out of the furnace could reach the most appropriate temperature.
Du Laosan didn't know the method of smelting ice vein marrow before.
This time Qin Liufeng specially taught the smelting method, so Du Laosan was not sure whether the smelting could be successful.
After more than an hour of fine-tuning, finally.
Du Laosan felt that the temperature of the flame in the furnace eye was almost the same, so he turned around and shouted: "Sentai, get the marrow quickly."
Sentai was second only to Du Laosan among the more than 20 craftsmen.
After hearing Du Laosan's instructions, Sentai immediately used the mining pliers to grab a small piece of ice vein mineral marrow.
Then gently place it on top of the flame in the furnace eye.
This small section of ice vein marrow is used for experiments, in order to accumulate experience and better smelt the remaining ice vein marrow.
The marrow showed no reaction in the furnace, but Du Laosan was very patient.
He kept lying down and carefully observed the smelting condition of the ice vein marrow.
His observation is not only comprehensively wrapped in fields, but also seen with r-eyes.
Although, within the field.
Everything is showing.
However, in the actual smelting process, many states and reactions of the ore must be observed with the eyes, or even smelled with the nose and ears, in order to truly judge the timing.
Otherwise, if you miss the best opportunity, the purity and quality of the ore will be greatly compromised.
According to the smelting method provided by Qin Liufeng, the ice vein marrow needs to be burned in the earth's core fire at 6,700 degrees for three full days.
After three days, it will be smelted into the Y state.
But at the moment when it becomes the Y state, the flame must be suddenly removed, otherwise.
This will cause the ice vein marrow to vaporize directly in the continuous high temperature.
Not only will the hard work be in vain, but a precious ore will also be wasted.
In this way, Du Laosan, Sentai and the other three craftsmen took turns taking care of it for three days, always paying attention to the smelting situation of the ice vein marrow.
After all, if you always let one person.
No one's eyes can bear to observe the flames at such a close distance.
Finally, three days passed, and the first ice vein mineral marrow used for testing slowly melted into a liquid under the gaze of Du Laosan and others.
Before they could breathe a sigh of relief, a stream of light blue smoke rose up from the melted liquid of ice vein marrow, quickly vaporized, and escaped from the vent of the smelting furnace.

"Quickly retreat to the center of the earth, the fire is coming fast!"
Du Laosan shouted loudly.
The others quickly followed suit and instantly changed the formation of the furnace eye, sealing the flames in the furnace eye.
The flame was sealed and the temperature in the furnace dropped sharply.
Only half of the ice vein marrow used for experiments was melted, and the remaining ones had to be smelted all over again because the temperature was not enough.
However, less than half of those that have been yyized have vaporized and escaped because the temperature was too high.
This experiment ended in this unsuccessful way.
For three whole days, not even one piece of ice vein marrow was successfully smelted, and only half of it was wasted.
The smelting of this ice vein marrow is really difficult, right?
For a moment, Du Laosan, Sentai and others all frowned, feeling tremendous pressure.
More than 20 people, convened by Du Laosan, discussed how to deal with it.
Everyone has come up with a lot of ideas, but most of them are just assumptions.
It is estimated that if they are actually adopted, the probability of success is very low.
A large group of experienced craftsmen were stumped in front of such a unique ore such as Ice Vein Marrow.
At this moment, a person said from the side: "It is actually very simple to smelt the ice vein marrow.
In fact, you can think of it if I give you some time.
However, for now, I am entangled in the characteristics of the ice vein marrow and have temporarily ignored it. stop."
Everyone looked around and saw it was Ah-Dai walking out of the room.
"Ah-Dai, if you have any idea, please tell me.
We are all anxious to death from the current situation."
Du Laosan seemed to have seen the savior and ran over quickly.
Duan smiled slightly, and then told him the solution.
His method is very simple, which is to add another formation to the smelting furnace.
Originally, there was only one formation in the Qin family's smelting furnace.
This formation could control the temperature of the earth's core fire, and it could also instantly isolate the temperature.
Dumb's solution was to set up a new formation of the same type next to this formation.
The first formation was used to control the appropriate temperature, and then it took three days to smelt the ice vein marrow into a yin body.
Once the ice vein mineral marrow is transformed into yin bodies, someone must immediately wrap these yin bodies with a domain and quickly move within the range covered by the second formation.
The temperature in the second formation is lower than the first formation, so after the Y body moves in, it will not vaporize and escape.
However, to control this process, at least two people who cooperate with each other and have a tacit understanding must complete it together.
When everyone heard this, they immediately felt that this method was indeed simple and easy.
Du Laosan was even more happy to fist-palm each other.
However, he still had doubts.
"Master Dumb, the method you mentioned is indeed a first-class good method, but it uses the domain to wrap the body of ice veins and mineral marrow.
Then move to the second formation.
This process will only affect the energy in the body of the person under control. , It will consume a lot of money.”
Du Laosan's worry is not without reason.
The realm of practitioners.
It also requires energy to maintain.
The high temperature of the furnace eye will aggravate the energy consumption.
What's more, the formation to control the temperature in the furnace also requires energy to maintain, and the y body must be wrapped in a domain to move in the high temperature.
These actions require strong energy support to be completed.
It's like holding an icicle into a fire and stirring something, and being burned by the flames.
The icicles themselves will melt and be consumed.
Dui nodded when he heard the words: "So, everyone should take turns to help, and I will also help.

I believe that if everyone works together and is more careful, there will definitely be no problem."
Everyone discussed for a while and felt that this was indeed the best solution they could think of at the moment, so they all nodded and agreed.
Subsequently, the smelting of the ice vein marrow officially began.
Du Laosan chose a good craftsman to cooperate with him and started to make the first batch, while Du Laosan kept watching.
Occasionally, a warning will be given.
"The lower part of the ice vein marrow will soon melt."
"The first formation maintains the temperature, and the second formation has a higher temperature.
Now the control field moves the Y body over."
"Shan Li, why are you still dazed?
Go and get Wen Yu's bottle to collect the essence of the ice vein mineral marrow."
All this was what Ah-Dai was reminding them of.
Before, Dumb's reminders were only spoken occasionally.
Now, it is seen that the ice vein marrow has been smelted bit by bit.
Dumb’s reminders became more frequent.
It took a full two hours for a piece of ice vein marrow as big as a brick to be completely smelted into liquid.
A large piece of liquid smelted from ice vein marrow can fill a small warm jade bottle.
The first furnace was successful.
The nervous mood of Du Laosan and other craftsmen only relaxed at this moment.
He wiped the sweat from his forehead and turned around to give Ah-Dai a bear hug.
"Brother, it's all thanks to you this time."
Du Lao San was hugged by the sweaty smell, and Du Lao San didn't mind being dirty.
He just smiled.
It seemed that he was really happy for Du Lao San: "Okay, Du Lao San, let's get ready to start the next one.
The sooner you finish it, the better it will be delivered earlier.”
Du Laosan nodded heavily, turned around and shouted to the craftsmen: "Brothers, cheer up, let's continue."
The ice vein marrow that Du Laosan and the others need to refine this time totals 150,000 kilograms, which is 15 pieces the size of bricks.
Once the furnace is successful, it will be smelted into 10,000 kilograms of marrow.
An ordinary cultivator or mortal would not even be able to pick up such a heavy object.
Fortunately, most of these craftsmen were pretty good.
In the past sixty days, including the previous test, Laosan and the others had smelted sixteen furnaces in total.
However, during the refining process, some small songs still appeared.
Sentai didn't know whether he was too nervous or too tired.
When he was in charge of refining one of the furnaces, there was an error in the process of wrapping the Y body with the domain, causing the ice vein marrow to contain nearly one-tenth of the gas.
Fortunately, Ah-Dai took action in time so that no more wasted.
It was originally scheduled to be completed in three months, but Du Laosan and the others completed it in just over two months, and the success rate and loss rate were also satisfactory.
He ordered someone to report it, and immediately a Qin family master from the early stage of Earth Immortal came to the small courtyard with a group of immortal guards and took away the refined ice vein marrow essence.
After sending away the guards who came to get the essence, the craftsmen finally relaxed.
They surrounded Ah-Dai, the biggest hero, and threw him into the air and caught him, cheering in celebration.
Then, Du Laosan gave the order, and everyone ate and drank for three days and three nights before resting drunkenly in the courtyard.
After more than two months, everyone was almost exhausted.
Now that there was no pressure, everyone naturally slept very comfortably.
These stout men usually don't pay much attention to their appearance.
Everyone was drunk at the moment, and after a while they snored like thunder, like a strange music.
Duan smiled and looked at the people lying on the ground exhausted, then came to the room alone and started practicing with peace of mind.
Du Laosan and the craftsmen slept for two days and three nights.

When they woke up, it was already the morning of the fourth day.
This mission was completed quickly and well, and everyone was on vacation for the remaining half of the month. then.
Each craftsman said hello to the Qin family and went out to visit the city on Zhiyang Star, so they could buy some things back.
As a craftsman and servant of the Qin family, I originally had the opportunity to take leave once a year, but this time I completed the task ahead of schedule.
So it was an extra vacation, so everyone was naturally in high spirits.
Du Laosan asked Ah-Dai to go out, but Ah-Dai refused.
When leaving, Du Laosan couldn't help but shook his head and sighed to himself that Ah-Dai was indeed an idiot.
He didn't even go out to play, and instead hid in his room to meditate.
However, I felt relieved after thinking that although the other party was named Dumb, he was stronger and more knowledgeable than me.
The saying "God rewards those who work hard".
It still makes sense.
With everyone out, it was rare for Ah-Dai to have more than half a month of practice time.
The craftsmen also wanted to restore Ah-Dai's innocence.
Under the leadership of Du Laosan, they went to the steward's room together as soon as the half-month vacation ended, and took the only one-month vacation this year.
Dui was ruthless enough that no one would bother him.
He simply didn't leave the room and practiced beautifully for more than a month until everyone's vacation was over.
After returning to the small courtyard, he was willing to finish his training and come out.
"Master Dumb, you have been in seclusion for so long this time, will you have another breakthrough?"
A late-stage master craftsman passed by him.
Laughing and joking with him.
Du Laosan, who was next to him, laughed and scolded: "Shan Chongfei, what nonsense are you talking about?
A state like Master Dumb's, which has been practiced in seclusion for hundreds or even thousands of years.
It has only been less than two months.
It is not so easy to break through."
Not thinking about it, Ah-Dai nodded seriously: "There is some progress.
But we have encountered a bottleneck."
Originally, the craftsman asked casually, but to his surprise, Ah-Dai actually admitted it.
Now a large group of craftsmen gathered around him.
"Master Dumb, you have really made a breakthrough."
"Bottleneck, doesn't that mean that Master Dumb, you will become more powerful soon?"
"By the way, Brother Sentai, I only know that Master Dumb is an immortal, but what state of cultivation is he at now?
Is it the late stage of mortal immortal or the early stage of golden immortal?"
Everyone was discussing and surrounding Ah-Dai.
It seemed that Dumb's progress was just like their progress.
Everyone was inexplicably excited and genuinely happy.
Looking at these rough men, Ah-Dai felt a little warm in his heart and felt an inexplicable touch.
When he said that his cultivation should be around the late Golden Immortal stage, everyone was in an uproar.
No one thought that this seemingly young immortal could turn out to be such a powerful master.
However, he was still surprised, and he was admired.
Dui was still the same Dui as before, and he still liked to laugh and chat with them regardless of each other.
When the craftsman returned from his vacation, the work in the courtyard naturally started again.
On the fifth month after the Ice Vein Marrow, everyone had gradually forgotten about the matter of smelting the Ice Vein Marrow.
Suddenly, another servant of the Qin family came to inform Du Lao San that they had smelted the Ice Vein Marrow last time.
The task of marrow was completed very well.
It was not only the fastest in completion time, but also the one with the best smelting quality.

In order to reflect the Qin family's family tradition of rewarding meritorious deeds, Lord Qin Liufeng wanted to personally reward the craftsmen.
Du Laosan and others were naturally very happy when they heard this, and ordered everyone to tidy up their appearance, and then waited quietly in the courtyard for Lord Qin Liufeng's arrival.
After waiting for a while, Earth Immortal Qin Liufeng finally arrived, leading several immortal attendants.
"Who is the chief craftsman here?"
Although Qin Liufeng remained majestic this time, there was a smile in his eyes as he slowly swept over the people present.
Du Lao San hurriedly took a step forward, bowed and said, "It's the villain Du Lao San."
Qin Liufeng smiled and nodded: "Du Laosan'en, you have led your subordinates to smelt the ice vein marrow this time.
According to the order of the family leader, I will reward you with 10 middle-grade Xianyin Stones."
"Thank you, Master of the family, for your gift.
Thank you, Lord Liufeng."
Du Laosan was overjoyed and carefully took the crystal from Qin Liufeng's hand.
Qin Liufeng then looked around at the other craftsmen: "Everyone followed the chief craftsman's instructions and completed the task well.
They all deserve credit.
Each of them will be given 3 middle-grade fairy sound stones as a special reward."
"Thank you, Master, for your gift, and thank you, Lord Liufeng."
All the craftsmen also bowed to express their gratitude, and then stepped forward one by one to receive their rewards.
After everyone received their rewards, Du Laosan stepped forward to report: "Sir, we were able to complete the task so well this time not only because of everyone's efforts, but most importantly, with the assistance of another adult."
Du Laosan wanted to help Ah-Dai to ask for a reward.
In the mind of this simple man, he had already regarded Ah-Dai as one of his own.
What's more, in the process of smelting the ice vein marrow this time, Ah-Dai's role was indeed crucial.
Du Laosan didn't want to see everyone get rewards, but Ah-Dai, the biggest hero, was ignored.
But how did he know that Ah-Dai didn't want to be in the limelight at all.
Du Laosan's report for being so good at making opinions can actually be regarded as causing trouble out of kindness.
"Oh, please tell me about another adult's assistance."
Qin Liufeng seemed to be a little interested.
Du Laosan responded, and immediately explained in detail who Ah-Dai was and how he helped them successfully smelt the ice vein marrow.
"Using the method of one furnace and two formations to solve the problem of smelting temperature of ice vein marrow is really simple and ingenious."
Qin Liufeng is also an expert in weapon refining, so he naturally knew that this method was ingenious as soon as he heard it.
"Among sister Yu'er's personal attendants, there is such a wonderful person."
Qin Liufeng sighed secretly, turned around and asked, "Where is this dumb guy?"
Du Laosan said at the side: "My lord, for this past year, Ah-Dai has stayed in the small courtyard and never went out.
Only tonight, Miss Yu'er ordered someone to specially summon him, so he went to Yu'er as ordered.
Miss Er’s place.
Therefore, he is not there at the moment.”
Coincidentally, the day when Qin Liufeng came to commend the craftsmen was also the day when Qin Yu had confined Ah-Dai in the small courtyard for a full year.
Under the reminder of his personal maid Xiaocui, Qin Yu finally remembered that he still had a servant like Ah-Dai, so he asked Xiaocui to come to call Ah-Dai to pay him a visit.
"Well, Mr.
Du, I hope you will work hard and do your job well.
The Qin family will not treat you badly."
Qin Liufeng casually said a few polite words and left the courtyard.
Flying in the air, a smile appeared on his stern face.
"The attendant A-Dai who has reached the late stage of Golden Immortal is interesting.
Speaking of which, I haven't gone to see Qin Yu's cousin for some time.
Now I am going over to meet this strange man named A-Dai."
With a plan in mind, Qin Liufeng looked for the direction and flew directly through the air towards the Qin family like an arrow
