The materials for building the refining stove are very simple, they are all taken from the broken stones on the side of the mountain in Shishan Village, after making this qiē, Zhao Mu began to put firewood, these firewood are nearby trees that are cut down, first pour a little fire water to burn, and when the fire spreads, Zhao Mu threw a piece of brass into the stone stove.

Ordinary fire naturally can't refine copper with high heat resistance into copper water, but if you can only use ordinary methods, Zhao Mu can't refine the raw materials of gold soldiers with more than ten densities.

Therefore, he took a deep breath, followed the spirit refining steps in the Fu Bing Technique, slowly stretched out a palm, closed his eyes and carefully felt the more and more solid spiritual qi mass that his dantian had condensed here, although there was still some fire that had not yet been condensed into a spiritual seed, but it might as well Zhao Mu use a little spiritual energy.

He felt the aura of the dantian, subconsciously released, and soon, the aura surged up to the arm, and then flowed into the palm of the hand, poof, when the aura was entered into the firewood pile, suddenly, the flame rose suddenly, and the originally red flame core was gradually transformed into a small ball of green flame core.

"It's the Green Spirit Flame...... That's right. Seeing these green flames burning, Zhao Mu snorted lightly, and his expression became excited.

That's right, this is the spiritual fire mentioned in the Fu Bing Technique, and it is the most basic spiritual fire that has just gotten a glimpse of the refining matter.

If Zhao Mu condensed the spirit seed, then the spiritual fire he mastered would be even better, and it would be upgraded to the point where all the flames turned into green flames, instead of just the core part of the fireworks.

But despite this, it is enough.

With the copper block on the stone stove that was not the most perfect, soon, the copper block gradually turned into copper water, Zhao Mu did not pause his action at this, but kept inputting spiritual energy into the stone stove, and then grabbed a piece of copper with his other hand and added it.

Fortunately, after more than half a month, his strength is much greater than before, if a month ago, his strength could only carry a hundred pounds of heavy objects at most, then he can now easily carry two hundred pounds, and if he does his best, there is no problem in carrying a heavy object close to three hundred pounds, and his strength is almost twice as much as before.

Therefore, even if you grab dozens of kilograms of copper with one hand, you can barely complete the process.

Time, just when Zhao Mu was sweating profusely and his skin was red from the high temperature in the house, when Zhao Mu grabbed the twenty-seventh piece of copper and threw it in, and refined all of them into copper water.

Finally, he slowly withdrew his palm, stopped outputting spiritual energy, and the whole person sat down on the ground panting, but he didn't rest for long, he put on a set of high-heat-resistant industrial gloves, and began to make copper pots in the half-softened and half-condensed copper water.

The copper pieces that were thrown back and forth were basically more than sixty kilograms, but in Zhao Mu's spiritual power refining, the total weight was more than one ton of more than seven hundred kilograms of copper water, but it was finally refined by Zhao Mu into more than thirty kilograms of higher-quality copper water.

Almost fifty-six times the weight of the spiritual fire condensed, this is already the limit of Zhao Mu's current spiritual power strength, the high-density copper water at this moment has been refined, even if more spiritual power is transmitted, it is impossible to smelt it a single cent.

After a while, Zhao Mu finally used the dozens of kilograms of spiritual refining copper water to make a copper pot with a diameter of about half a meter in diameter in a simple and rough way.

When the copper pot finally cooled and solidified, Zhao Mu breathed a sigh of relief tiredly, and the first step was finally completed.

Before refining the soldiers, he had to make a copper cauldron that could withstand the limits of the Blue Flame Condensation.

Then he came down to rest for half an hour, and Zhao Mu began to continue to condense the copper pieces, and after having the copper pot, he directly threw one copper piece after another into the pot, and then smelted it into copper water.

Since the copper pot is not large, he smelted three pots before and after to finish refining all the copper blocks of more than three tons, and poured the copper water weighing more than 90 kilograms into the humanoid mold he had recently made by himself.

When the copper water was completely cooled, Zhao Mu knocked out all the clay molds of the humanoids, and when he looked closely, a bronze figure with very rough workmanship was finally created.

"It's done, Nima, it's not easy." When refining a few tons of brass, Zhao Mu had just condensed a few spiritual qi masses, and they were almost consumed, but fortunately, there were still spiritual runes in his chest that had been condensed for many years to continuously replenish the use of spiritual energy, I am afraid that just the process of copper smelting, with Zhao Mu's current little spiritual qi mass, it is estimated that it will take several nights to refine these tons of copper blocks.

Standing up and looking at the bronze man that had gradually taken shape, Zhao Mu's heart was full of agitation, drawing talismans, refining materials and shaping soldiers, and distracting.

Among the three steps of making the bean-sprinkled soldier gold man, the most complicated, spiritual power-consuming and time-consuming refining material was finally completed, which greatly increased his confidence.

Carefully look at the bronze figure in front of him, in order to save the money cost of the copper block, Zhao Mu only made the bronze figure only one meter five high, and the body is very thin, just looking at the appearance to describe this kind of humanoid figure, it can only be said to be skinny, almost skinny and bone-like form.

But the thinned bronze man refined, obviously will not highlight the ugly foreskin and bone appearance of human beings, and on the contrary, at first glance, there is a feeling of thinness and agility, very agile, under the mistake, Zhao Mu instead refined a bronze man that looks more agile.

If a human being is this tall and thin, he would only weigh about thirty catties at most, but this bronze man is different, because his total weight has reached almost a full two hundred catties.

Zhao Mu took out the density detection instrument, pounded his head and checked it, and finally measured that the current density of this bronze figure has exceeded ten points, reaching as many as thirteen points, which is a little higher than the twelve points required by the Fu Soldier's technique, which is obviously enough to meet the most basic requirements for condensing the copper soldier.

If Zhao Mu took out this body at this moment, which far exceeded the density of ordinary copper, and sold it, it was estimated that he would definitely be able to sell it to some metal research institutions for a lot of money, but he naturally wouldn't do it for no other reason, because this act was simply death.

At this point, the vast majority of the Jin Bing's production has been completed, and the remaining small part is to engrave the Jin Bing with rune carvings and spirit runes.

These rune carvings are specially created for the dead things in the rune soldiers, and their storage is very important, and the storage of the spirit runes is naturally indispensable.

If you want to make an analogy, the bronze man is an electric car, and these rune carvings are actually the power path system in it, and the spirit rune is the source of power.

After these days of practice day and night, Zhao Mu has become very familiar with the drawing talisman of sprinkling beans into soldiers, and the rune carving of Jin Bing is much simpler, which is naturally not too difficult.

Soon, Zhao Mubei stretched out his index finger, and slowly output his spiritual power, calmed down and began to draw the seal talisman carving on the bronze man's body, this process, except for a small difference in the painting of the bronze man's ankle carving, the other parts were completed very smoothly.

It took more than half an hour to refill this small mistake, and the whole engraving took more than half an hour.

After completing the carving of the bronze man, he carved a spirit rune on the back of the bronze man's head, and then connected the spirit rune with the previous rune carving.

In this way, the power source and the circuit will be connected, and the whole bronze man will be activated like a machine man.

I have to say that although these talismans are full of fantasy, in fact, they all show the brilliant science everywhere.

The spirit talisman was only practiced by Zhao Mu in the past few days, so he was not very familiar with the painting, but with experience, he carved it wrong several times, and finally completed it on the fourth engraving.
