In fact, he only needed to put the excess 1,600 or so runes he had exchanged into the cave heaven and he could continue to cultivate......

But in that case, the values of the other four elements will also be higher, and only half of the increased Jinxing aura can be used for cultivation.

Or, by indiscriminately manifesting and consuming the other four elements of aura, to maintain the balance of the five elements of aura, but that is obviously more extravagant and wasteful.

After a little accounting, the simplest and most cost-effective method is to supplement the aura of the gold line in a targeted manner!

Can it be done? Absolutely, and it's easy!

The tiniest unit of aura in the world is silk, and each of the five elements of aura is a trace of it, which is the basic monetary unit yuan.

Of course, in addition to being impartial, there are also those who will be biased.

For example, the gold element of pure five-silk gold aura, the wood element of pure five-silk wood aura, the earth element of pure five-silk earth aura, the fire element of pure five-silk fire aura, and the water element of pure five-silk water aura......

Or, four gold and one wood, three earth and two fire, gold wood and earth and two water...... There is no need to arrange and combine to account for the number of words, but there are basically various permutations and combinations to meet the needs of various spell formations.

If you count the thunder aura, wind aura, ethereal aura, dark aura, and ice aura...... and all kinds of bizarre aura, then the permutations and combinations of all these base currencies can make mathematics students scratch their heads for a while.

Except for those special spirit elements, the basic value of the five elements fluctuates around one yuan with the market.

The price of gold yuan is the highest, about 1.2 yuan, because among the cultivators of the five elements spirit root, the number is relatively small, but it will not be too excessive, after all, the talent is divided into five elements, and the gold bank accounts for one of them.

So, I went to the auction house in the Yi Bao Pavilion, swept away all the gold dollars and gold runes with similar prices, spent more than 600 rune yuan, exchanged about 500,000 gold yuan, returned to the cave, and continued to meditate.

The internal force value of 1500 at the beginning of the fifth level and the internal force value of 2350 at the peak of the fifth level require a total of more than 1.6 million internal force values.

It only took twelve or three days to consume 40,000 gold aura a day and transform more than 80,000 internal force values, and the gold yuan from the swept goods was consumed, and Lin Tuo's internal strength value was only 2,100 points, which is still a lot short of the upper limit......

Therefore, in this strange world, it is not easy to cultivate!

Since Lin Tuo crossed, almost half a year has passed, and it has been three or four months since he stepped into the Xiuzhen Gate, and the heavens of this world have changed from the hot and unbearable midsummer to the late autumn when the cold wind is gradually rising, and Lin Tuo is only six times dissatisfied.

Of course, this speed is already extremely fast, very fast, so fast that it is almost against the sky!

But don't forget...... What are the conditions for Lin Tuo?

There are bronze treasure eyes to assist in cheating, and the cultivation speed is more than 100 times that of ordinary people, and by mistake, all the "tripod weapons" that Lian Shanyun has cultivated for more than ten years have been absorbed.

Think about the average person...... Can't have too many selfish thoughts, no time to pick up the girl, and there is no time for vacation, although it is said that cultivation can extend the life span to a degree that is difficult for ordinary people to reach, but, meditation and practice occupy most of life, compared with ordinary people, it is difficult to say which one will move longer in life.

Fortunately, I am a player, not an indigenous person of this world!

Hearing the sound of careful collapse from the cave system, Lin Tuo sighed in his heart, but he didn't dare to wander at all, separated a wisp of divine thoughts, operated the idle sitting statue, stopped the cultivation of internal strength, turned off the alarm-like cave warning, and firmly stared at the newly cast sharp small knife directly in front of his body that was vertically inserted into the grinding tool.

The blade of Xiao Yidao was red, and it was obvious that it had not been long since it was taken out of the furnace, and it was slowly and naturally cooling in the air.

In the field of view of the player's interface, you can clearly see that the temperature of the surface of the sword is steadily decreasing from more than 1000°, 950°, 900°, 850°......

Almost!

Lin Tuo raised his attention unprecedentedly, pinched the thunder talisman in his right hand, and chanted loudly: "The five stars are illuminated, the five directions are brightened; Taibai is the army, galloping through space; the envoy thunders, and the golden light leads to the thunder palace!"

The lightning guide rune was full of light, and electric sparks began to burst out from Lin Tuo's left and right fingertips in an instant.

Although the carbon content of steel is different, when it is reddish at more than 8 to 900 degrees, it will be in an austenite state, and the carbon is dissolved in the γ iron to form a kind of interstitial solid solution, which is a face-centered cubic structure.

At this point, the steel structure loses its magnetism.

When the temperature decreases, the austenite slowly transforms into martensite, and the magnetic properties of the iron structure will reappear......

The way in which Jinguangmen uses lightning charms to engrave spells on the inside of the blade is to take advantage of the process of ferromagnetism from scratch and the transformation of the iron structure from austenite to martensite, and use electric current to induce the enduring spell pattern inside the iron structure.

Even though Lin Tuo has already understood the principle of technique, he still doesn't have much certainty, because the opportunity is fleeting!

The difficulty is many times higher than the timing of a perfect quenching, after all, it is only the pursuit of a moment, and this requires you to make the most correct and stable operation in the shortest possible time.

It's like a swimming competition, where the difficulty of stepping on a gun into the water requires you to come to a difficult 10-meter platform at the same time as stepping on a gun......

Between the ten fingers of the two hands, the arc crisscrosses, as if five arc welding torches were fired at the same time.

Lin Tuo endured the numbness of his fingers and the high temperature that caused his "-1, -1" to continue to bleed, and placed the ten fingers of his hands in front of and behind the blade of the high-temperature sword blade.

The arc pierced the sword body, causing sparks, and with the trembling of Lin Tuo's fingers, from top to bottom, he quickly sketched a series of complex marks inside the sword body.

This is not only a technical job, but also an artistic work, the finger pressing, the fingering changes from top to bottom, the complexity is no less difficult than that of piano playing.

If the piano plays the wrong note, it just sounds awkward, and if the process is wrong, it will be reimbursed by a charm, and the carrying limit of ordinary runes is only three charms.

Coupled with the current paralysis, high temperature burning, finger twitching out of control, none of them is the most normal, even if you are very talented, you can already stand out from the crowd if you succeed in two, and you are a master level when you succeed in three, and your craftsmanship is at its peak!

It is precisely because of this that the three-attribute best equipment, especially weapons, is expensive.

Moreover, there is no way to take a trick in this matter...... For example, in order not to tremble your fingers, you can fan the wind and reduce the burns on your fingers, but at the same time, it will inevitably accelerate the cooling rate of the surface of the sword body, just like the contradiction between the distance from the furnace when the Sugang method is built......

It's too late, it's fast, and with just one breath, Lin Tuo's ten fingers have completed the extremely complex inscription from top to bottom, and he inserted the sword and his own hands into the cold spring water together, cooling and quenching!

Failure, sure enough, success it!

Precise cooling, quenching, annealing, and then putting the sword on the existing grinding machine to quickly polish and shape, and after thirty-five more failures, his first attribute equipment was finally baked!

Sharp small B knife, attack 4-5, durability 44, toughness 39, strength +1!

Although the special attribute is up, because of the cooling time in the air, the property of the base plate itself has come down......

This forging method is really mysterious, and it is not easy to exhaust it!

After creating the first attribute equipment, Lin Tuo was finally able to rest his breath and solve the problem of the shortcomings of Dongtian's spiritual energy......
