Jin Huiyun also knew that Lin Qinghe wanted to cultivate to the Yuan Infant Stage, and he didn't know how much time it would take, so he had to give up regrettably.

Everything was ready, and Jin An began to refine.

He pinched his fingers, and a flame appeared out of thin air in front of him, the fire looked golden, and it was obviously very hot, but the temperature in the room did not increase significantly.

Jin An is very good at gathering the temperature of the flame in a relatively small space, so that the temperature of the flame can be more concentrated, and the effect of refining will be better.

Jin An said: "A pound of pig iron." ”

Lin Qinghe used his spiritual touch to grab a pound of pig iron and throw it above the flame in front of him.

Jin An refined the weapon this time, because the refining equipment was relatively large, and a person's spiritual power and vitality were limited, so he couldn't waste it at all, so he asked Lin Qinghe to cooperate with him to do some auxiliary work.

As soon as the pound of pig iron touched the flames, it melted rapidly, and countless gray substances were burned out, and they were vaporized in an instant, dissipating between heaven and earth.

In the end, a pound of pig iron only got a thumb-sized drop of fine iron.

Jin Huiyun took a breath lightly, she also said before that just to build a boiler, it would not use so many materials, but she didn't expect that there would be such a big cost from pig iron to refined iron, no wonder Xiao An asked her to prepare so many materials.

In a short time, thousands of catties of pig iron were refined into refined iron.

After that, Jin'an refined other ores in the same way, and the quality of these ores did not meet the requirements of the boiler required for the production of Peiyuan liquid, and it had to be refined.

After all the ore has been refined, there is only a small pile of ore the size of a thumb left in a huge workshop.

Jin Huiyun muttered, "The cost of this refining weapon is too great, right?" Tens of thousands of catties of things, after refining, one person can hug them......"

Jin An took a breath and said, "Auntie, I'm afraid you have a misunderstanding about the refining weapon. In the process of refining, although some wastes have indeed been vaporized and disappeared, the density of these things has been greatly improved. ”

"Really?" Jin Huiyun didn't believe it, and walked over to pick up a piece of Mithril at random, but his hand sank and he almost didn't hold it steady.

She was surprised: "This must be seven or eight taels, right?" ”

Just the one the size of a thumb weighs nearly a pound? Isn't that incredible?

Jin An laughed and said: "The purity of these silvers prepared by my aunt is relatively high, and after refining, the weight lost is relatively small, and this one is nearly nine taels." ”

Zhang Haoran picked up a refined iron and turned it upside down, saying: "So, Xiao An's refining process is actually equivalent to changing the internal structure of the substance and making it reorganized?" makes them denser. In fact, this thing can no longer be called iron. Just like carbon and diamond, they are both made up of the same elements, but the structure is different, making them two different substances. ”

Jin An nodded with a smile: "Yes, that's what Brother Haoran said." ”

He took out a small dagger from his waist and said proudly: "You see, this is what I refined two days ago, either I blow it, or diamonds, and my dagger can also make it cut in two!" ”

In the Qi training period, he has not yet cultivated the true fire, and can only refine the weapon like a mortal striking iron, at most, he has a fire control decision, which can increase the temperature of the flame and improve the forging effect.

But the overall efficiency is still low, and although the things practiced are good, they are far from amazing.

Now it's different, the foundation building period has cultivated the true fire, refining with the true fire, that is not a quantitative change, but a qualitative leap, the weapon he has created now can be said to have been out of the category of mortal weapons.

It's a pity that there is a material that can't be found, otherwise, he can refine the flying sword!

Jin Ping's eyes lit up, took his hand, and said, "Okay, there is such a treasure that doesn't even tell me." ”

He is doing some tasks now, and sometimes he uses a gun too ostentatiously, and if he uses a cold weapon, the effect is not particularly good.

He glanced around, found the steel bar on the window, and slashed it with the dagger, and then felt very relaxed, and cut off the steel bar that was thicker than his thumb, not to mention like cutting tofu, but the resistance was really not too great.

He gasped, looked at it over and over again, and said, "Xiao An, give me this dagger." ”

Jin An shrugged: "This dagger is the first time I have refined, in fact, there are still many things that are not done well, and the materials are also found temporarily, not very good, if I replace it with better materials, I can do better." ”

Jin Ping said: "What materials do you want, let grandpa help you get it, I will use this dagger first, and when you refine a better one, I will change it." ”

Sure enough, building a foundation is the starting point of cultivation!

During the Qi training period, Xiao An also simply practiced some things, but it was not so amazing at all.

It seems that he has to work harder and strive to enter the foundation building period as soon as possible.

Zhang Haoyang and Zhang Haoran both gathered around and played with daggers to cut steel bars.

As long as they are men, there is no one who is not interested in weapons, they advocate violence in their bones, so after Zhang Haoyang and Zhang Haoran saw the power of the dagger, they also asked Jin An for it.

Jin An also agreed one by one.

Jin Huiyun advised: "This thing is too sharp, beyond the imagination of ordinary people, don't go out to show off easily, at this stage, our family still can't attract too much attention." ”

Dad is right, what the Jin family lacks most now is time, as long as he can give Xiao An decades of time to accumulate, once he breaks through to the Yuan Infant Stage, there are not too many things in this world that can threaten him, at that time, it is the time for the Jin family to really sit back and relax!

Zhang Haoran said: "Mom, we are already adults, and we still know the severity of these things. Don't worry, my brother and I will just entertain ourselves. ”

There is such a dagger here, don't say anything, I have confidence in my heart!

Although they did not join the army, since they were children, they would go to their grandfather's side every winter and summer vacation to receive military training, so their physical fitness and fighting skills are not bad, and with such an indestructible dagger, what else is there to be afraid of?

Jin An said: "Brother Haoyang, Brother Haoran, what kind of dagger style do you like, go back and describe it, I will try to refine it for you according to the style you like." ”

Zhang Haoran smiled: "There is also a customized service?" That's a good idea. When I think about it, I will go to some museums and refer to it. ”

With such a sharp weapon, he has to think carefully and strive to build it perfectly.

Jin An said to Lin Qinghe again: "Lotus, I'll refine it for you, what style do you want?" ”

"Okay, in terms of style, I'll think about it again, but I don't want it to be too long, let's shrink it a few times, it's too big, and it's not convenient for me to carry it around."

She figured that it would be enough to estimate the size of a regular fruit knife, and that she didn't really need a dagger much anyway.

As she spoke, she handed over a jade bottle and said, "You take a Qi Enhancement Pill first, replenish some vitality, and wait for the state to recover, and then proceed to the next step of refining." ”

When refining materials, you can also take your time step by step, and you can also take a break in between.

But when it comes to the real refining of the instrument, it has to be refined in one go, and without panting in the middle, it must be restored to the best state to ensure the success rate.

Jin An took the jade bottle, poured a Qi Pill, and poured a Qi Pill, a stream of essence vitality gushed out, and he hurriedly guided it into the dantian to restore the vitality consumed during the previous refining.

After waiting for a while, Jin An returned his body to its best state, he opened his eyes, and said with great interest: "Okay, now let's start showing the real technique!" ”

He pinched a finger, and a golden flame resurfaced, and he said, "Refined iron." ”

Lin Qinghe grabbed all the refined iron pills, and those refined iron gradually turned into molten iron under the scorching flames.

"Refined copper."

Lin Qinghe grabbed the refined copper pill again, the copper shot melted, and the copper water merged into the molten iron.

"Tungsten spirit."

Lin Qinghe grabbed the tungsten gold pill, the tungsten essence pill melted, and the tungsten water was integrated into the molten iron.

“……”

As the same material was added to the molten iron, the color of the molten iron was also changing, and finally, Jin An no longer let Lin Qinghe continue to add materials, he began to control the flame to slowly cool down, from gold to orange, at this time, the liquid also slowly began to half-condense and solidify.

Jin An controlled the expansion and pulling of the liquid, and gradually formed the appearance of a boiler.

The structure of the boiler for the production of rejuvenation liquid, Jin An has seen it countless times, and it has long been deeply imprinted in his heart, at this moment, he effortlessly created the shape of the boiler with that mass of liquid, and all the structures inside are not bad at all.

"Mithril!"

Jin An let out a low roar, Lin Qinghe hurriedly grabbed some Mithril pills, Jin An split a flame and melted Mithril, and then Lin Qinghe controlled Mithril and outlined several formations on the inner wall of the boiler.

There are temperature control arrays, extraction arrays, slag discharge arrays, condensation arrays, fusion arrays, and Hedan arrays......

She had all the magic circles possessed by a series of alchemy furnaces on them.

In fact, there are some runes and formations in the inheritance that Jin An obtained, after all, the refining weapon must be able to know the rune seal and formation, otherwise what is the use of just a blank? The finished product obtained by refining the weapon is because of the runes and formations engraved in it, so it will become so powerful.

It's just that the inheritance that Jin An got is all combat runes and formations, such as increasing speed, strengthening hardness, increasing sharpness, and armor-piercing and defense-breaking......

He was really not good at this kind of magic circle needed by the alchemy furnace, so Lin Qinghe cooperated with him to imprint it.

It took a long time for Lin Qinghe to finally imprint all the magic circles into it, after all, this method of using spiritual power to draw talismans in the void requires very high control of spiritual power and vitality, if it weren't for Lin Qinghe's frequent use of spiritual touch to select seeds suitable for cultivation, she might not be able to withstand such a difficult task.

After branding all the magic circles, Lin Qinghe wiped a handful of sweat and nodded to Jin An, so Jin An slowly continued to adjust the temperature of the flame, suddenly cooled down, suddenly heated up, and after a few times, improved the toughness of the boiler, and then removed the flame.

After the boiler finally dropped to room temperature, Lin Qinghe, who had been prepared for a long time, played a small ice talisman to make the temperature of the boiler continue to drop.

After the temperature of the boiler dropped to zero, Lin Qinghe played another ice talisman.

The Ice Talisman is an evolved version of the Little Ice Talisman, and with the improvement of Lin Qinghe's strength, the Little Ice Talisman has been able to control the temperature to convert between 0-30 degrees. The Ice Charm is even more powerful, capable of controlling the transition from -300 degrees to 0 degrees.

This is equivalent to an alternative annealing.

When the annealing is completed, the boiler is completely refined, presumably for the production of rejuvenation liquid, the volume of this boiler is half smaller, but just look at the appearance can know that this boiler is much better than the boiler that produces rejuvenation liquid.

In addition to the core boiler, some other piping equipment can still use the original equipment, and Jin'an also took this problem into account when refining the boiler, and kept all the interfaces as they were for easy docking.

Seeing that the thing was finally successfully refined, Jin Huiyun was a little excited: "Xiao An, can you refine a furnace now to see the effect?" ”

"That's fine."

Jin Huiyun asked the security personnel to come in, moved the freshly baked boiler to the next building, lowered the original boiler, and installed the boiler.

When the security captain entered the door, he saw that the materials that had been piled up in the room had been emptied, and a boiler suddenly appeared, his eyelids jumped, but he didn't say anything, and directly called a few trustworthy brothers to come in and move the things away.

In fact, the veterans who were selected by Jin Tiannan and arranged to be in charge of security work in this factory were all very loyal to the Jin family, and there was no need to worry about them leaking some secrets that should not be leaked.

Of course, there are countless doubts and shocks in their hearts.

It's just years of education that make them hide it all in their hearts, only carry out tasks, and not be curious about anything else.

With the help of the security guards, all the machines were installed, and then they went to ship another batch of medicinal herbs.

After sending out the idle people, Lin Qinghe used a dust removal charm again to clean up all the mechanical equipment, and then put the medicinal materials he wanted into categories and installed them at the inlet above the boiler.

The power is turned on and the boiler is humming.

Jin Huiyun said nervously: "Lotus, how is it?" ”

Lin Qinghe said: "Aunt Yun, don't worry, it will take two hours to refine a furnace of Peiyuan liquid." ”

In these two hours, Lin Qinghe has been paying attention to the situation of refining medicine in the boiler with his spiritual touch, everything is going well, and in two hours, the boiler makes a dripping sound, a valve automatically opens, and the refined Peiyuan liquid inside flows out, after cooling, packaging, and finally forming a finished product.

From the other opening, the residue was also discharged, and the inside of the boiler was clean and there was no residue.
