After a while, he calmed down, and then, a huge question arose in his heart, "Obviously, Steward Xie said that this Soul Breaking Sword, the old monsters of the Alchemy Hall can't dissolve it, obviously, this Soul Destroying Sword is extremely difficult to handle, even if the iron essence can deal with the remnants of the lower blood weapons, it will never be neat to this extent." ”

Speaking of which, Xu Yi couldn't figure out the reason, but it was normal, except for a great refiner like Elder Song, who could get a glimpse of it from the secret collection of classics, and where did others go to find out.

It turns out that the decomposition ability of this iron essence is different from that of the refiner to decompose the remnants.

The refiner needs to peel off the cocoon, skillfully use the knowledge of the balance of the five elements, and peel off the metal raw materials little by little.

The essence of the refiner's decomposition of the remnants of the remnants is to untie these knots one by one, incinerate them with fire, and leave only the metal raw materials.

However, the decomposition of the remnants of the iron essence is completely a violent extraction method, extracting the metal raw materials from the small lumps, and only the grade of the remnants of the remnants of the iron essence is affected by the extraction speed.

However, because the higher the grade, the better the balance of the five elements, and the tighter the winding of the five elements, the greater the difficulty of extraction.

It boils down to this Soul Breaking Sword, and the two extraction routines naturally produce different decomposition results.

This Soul Breaking Sword was made by the Soul Breaker with a level that was almost a miscellaneous worker, and the five elements inside were barely balanced, but the use of balance was completely chaotic.

Others refine a blood weapon, and the knots entwined by the five elements inside are always feasible, and the knowledgeable master can always find a way to crack it and quickly complete the decomposition.

And the Soul Breaker Son, it is completely lucky, relying on the heavens, not according to the routine to play cards, the forged Soul Breaking Sword is messy with the five elements of the knot, there is no trace, even if a group of great refiners get this Soul Breaking Sword, there is nowhere to start.

On the other hand, the iron essence didn't care about the five elements at all, and directly extracted the raw material of the three yin wood, and because the five elements inside the soul breaking sword were very weak, the restraint on the raw material of the three yin wood was very small, which caused the astonishing decomposition speed of the iron essence.

Xu Yi didn't know the inside story, but he didn't bother to study it in detail, so he started the great cause of trial.

In the past few days, every night before going to bed, he would flip through the three refining secrets he had obtained from the Alchemy Hall.

He has an amazing memory, and he has already cooked the three secret books and the rolling melons on his back, and what he lacks is to operate it by hand and understand it specifically.

Before coming to Guangwu Pavilion, he traveled to many markets, spent a lot of money, and purchased refining accessories in the best condition and most suitable for novice exercises.

In addition, he even invested money to purchase enough Bigu Dan for a month to replenish his energy.

Counting the cost of getting these three yin wood out of the alchemy hall, he had spent nearly 30,000 gold to refine these three yin wood.

After the battle of the Black Dragon Hall, at the peak, he had more than 28,000 gold in his pocket, and today he extorted 11,000 gold from the Yun family, excluding the 2,000 gold given to Gao Jun Mo, he had a total of more than 37,000 gold in his pocket.

In the past few days, that is, to purchase tonic medicine for Qiuwa, it cost more than 4,000 gold, of which 2,000 gold was "sponsored" by Yun Gongzi.

Except for the 3,000 gold that he gave to Yuan Qinghua to purchase treasure medicine and inquire about the whereabouts of the spiritual land, Xu Yi should still have 30,000 gold in his hand.

However, just to test the crazy idea in his heart, and for the unavoidable Sanyin Wood, he now has only more than six hundred gold in his pocket.

Such a price is not insignificant.

Since the cost is huge, how can Xu Yi be willing to delay time.

After taking a Bigu Dan, a cool feeling rose in his abdomen, and he took out several large bags of auxiliary materials that had been prepared earlier, as well as a bucket of blood drawn from his body that had been prepared earlier, gathered the fragments of Sanyin Wood, and put them on one side.

Immediately, he opened another furnace and adjusted it to the fire gathering gear, and in an instant, a cluster of blue flames jumped out and quickly filled the entire furnace mouth.

Xu Yi grabbed a few pieces of Sanyin wood, a small amount of five elements of auxiliary materials, and put them into the furnace together, and after a while, the Sanyin wood and auxiliary materials in the furnace were automatically wound and gathered into a red iron ball the size of a chicken.

Immediately, Xu Yi extinguished the fire, extracted a small amount of blood, and poured it on the iron pill, and in an instant, the splendor in the refining room was magnificent, colorful and dense, and after a while, the color of the iron pill converged, and the color of the iron pill became more and more red.

After waiting for about a stick of incense, the color of the iron pill did not change, Xu Yi grabbed out the iron pill, placed it at the mouth of the furnace, called out the fire, picked up a small forging hammer from the forging frame near the left, and began to temper.

One hammer, two hammers......

The perception was fully released, and every contact between the forging hammer and the iron pill was clearly and accurately projected in the depths of his mind, and soon, Xu Yi sensed different tremors, which amounted to dozens of kinds.

Knowing the secret secrets, he already knew that this tremor was a sign of the five elements entwined and combined, and each combination was different, either in accordance with the law or against the law.

The essence of the exercise is that Shunchang rebels against the death, disintegrates the unreasonable combination, and distributes the reasonable combination, when the whole blood instrument, the less the unreasonable combination, the more reasonable the combination, and the forging tool will be completed.

The quality of the blood weapon, in addition to the quality of the material used, depends more on the level of the forging tool.

When a finished blood vessel, the less unreasonable combination, the better the quality of the blood vessel, otherwise, the worse, and if there is almost no unreasonable combination, then it has reached the extreme, which is the legendary best blood vessel.

However, the way of heaven is to make up for the deficiency of the loss, and the best blood weapon is made against the sky, and it is a rare existence.

On the contrary, when the unreasonable combination in a blood vessel even exceeds the reasonable combination, it becomes a waste vessel.

No, it didn't take long for Xu Yi to exercise a waste weapon.

At the moment when he smashed down on the ninety-third blow, the iron pellets, which had become pieces of iron, were forged into several pieces.

The failure of the exercise did not make Xu Yi feel the slightest decadence, and he had already made full mental preparations for the difficulty of refining this time.

The reason why I don't use all the three yin fragments in one trial is to know that I will encounter the results in front of me countless times.

Exercising separately saves time, and likewise, saves accessories and blood.

Putting the pieces together and tossing them aside, he began a second trial.

This time, however, it lasted a lot longer than the last time, and it took a hundred and thirty-four hammers to break the iron.

Obviously, the previous workout, although it failed, allowed him to make great progress.

Third, fourth......

It wasn't until the sixth exercise that the hammer fell nearly three hundred times, and after the failure was over, Xu Yi stopped exercising, put the remnant fragments that had gathered into a small pile, and invested them in another refining furnace, transferred them out of the fire, and put in the iron essence.
