When Shopkeeper He saw the three of them returning, he immediately greeted them with a smile.

What shopkeeper, those materials are prepared...... Ji Yuanqiu couldn't help asking.

Ji Gongzi, Ye Gongzi and this brother, you come with me.

The three of them followed behind Shopkeeper He and entered the inner room of the store.

Look, Shopkeeper He immediately pointed to the materials on the table.

Ye Lin approached the table and watched it carefully, the weak water was heavy, and the materials such as pine wood and century-old tungsten steel were all bought one by one.

Okay, seeing these materials, Ye Lin couldn't help but shout two good words again and again.

With these materials, he can create a treasure that is truly his own.

With his current cultivation in the Yuan Shen period, if there is a good Xuan Bao, it is bound to get twice the result with half the effort.

Whether Ye Gongzi was satisfied or not, Shopkeeper He took the opportunity to ask Ye Lin.

Ye Lin nodded and said, "Very satisfied." ”

If there is business in the future, I hope to take care of the small shop, and the shopkeeper He has a smiling face.

Ye Lin put these materials into the mustard seed bag one by one and discussed it with Ji Yuanqiu.

The two have made up their minds and are ready to go to the imperial city of the sin capital.

Brother Ye, the consumption in this imperial city is extremely high, and I am afraid that you and I will entangle......

Ji Yuanqiu was shy, and couldn't help but speak.

Brother Ji, don't worry, I still have some money on me for you and me.

The underworld man on the side touched his head, and said secretly in his heart: "How much money is left on the master, how do you feel that you can't spend it." ”

The three of them walked through some of the streets of the inner city, and as they continued on, they were greeted by a barren mountain range.

The Imperial City is located on the highest point of these mountain ranges.

The three of them were not in a hurry along the way, walking slowly while enjoying the scenery on the way.

At night, the trio chose a mountain range to camp in, which was still two days away from the Imperial City.

In the past two days, Ye Lin wanted to refine the Xuanbao.

At night, Ye Lin did not rest, but took out one material after another from the mustard seed bag.

He glanced at these materials, his eyes fell on Yiye Bianzhou again, and he couldn't help but shake his head, Yiye Bianzhou is a good sword, but its toughness is still too brittle after all, with my current strength and understanding of the way of the sword, I still need a heavy sword.

Ye Lin's expression moved slightly, and a golden bucket, a loose sword, and a diamond platform immediately appeared in his hand.

These three magic weapons, with my current strength, are not suitable for using these.

There was no reluctance in Ye Lin's eyes, and a trace of Taiyin True Fire was released in his hand, pouring into these magic weapons with his strong True Yuan.

Under the high temperature forging, these magic weapons gradually melt and finally decompose into pieces of material.

In particular, the iron essence decomposed in the Vajra platform can greatly improve the material of the sword.

He took out another leaf of the boat in his hand and decomposed it with high temperature.

One by one, the true elements were poured into the Taiyin True Fire, making the temperature of the True Fire extremely high.

Within one night, the magic weapons had broken down into materials.

At the same time, due to the abnormal high temperature, most of the impurities of these materials have been removed, and these materials have been in their original state.

This night kept pouring in the true element, which made Ye Lin a little tired.

Brother Ye, Ji Yuanqiu glanced at Ye Lin.

Ye Lin just retreated from that state, wiped the beads of sweat from his forehead, and said, "What is Brother Ji looking for me?" ”

Since Brother Ye needs to refine the Xuanbao, we will be stationed here for a few days, and Brother Ye wants a sword, I don't know what to ask for.

Ye Lin thought for a while, and replied: "The heavy sword, the toughness is enough, and the sword is sharp enough." ”

Ji Yuanqiu nodded and said, "Then you need a good fetus, I don't know if Brother Ye has a good fetus." ”

Fetal equipment, what is it, Ye Lin wondered.

Eh, Ji Yuanqiu was stunned, and then said with a smile: "Brother Ye doesn't know, a good weapon is not pure and directly refined, but a very good fetus. ”

This mould is the model of all your casting, Ji Yuanqiu explained.

I see, Ye Lin muttered a few words silently, and then said, "I don't have this thing." ”

Ji Yuanqiu smiled mysteriously and said, "It doesn't matter if you don't, I have." ”

Seriously, a glimmer of light flashed in Ye Lin's eyes.

Ji Yuanqiu's heart moved slightly, and he took out a two-meter-long fetal from the mustard seed bag, this is a mold made of a heavy sword, Brother Ye will see if it meets your requirements.

Ye Lin glanced at the fetal tool, nodded, and said, "It's just right." ”

Thank you, Ye Lin said to Ji Yuanqiu.

Brother Ye doesn't have to be like this, Ji Yuanqiu nodded.

Ye Lin was no longer polite, and immediately placed the fetal equipment neatly.

He exhaled deeply, calming his mind.

For Ye Lin, refining a Xuan Treasure is not an easy task, at least with his current cultivation, there are still many difficulties.

But if he didn't try, he wouldn't be reconciled.

So it was a brave and challenging act.

For half a day, Ye Lin didn't touch these materials, or rather, he wasn't in a hurry to forge them.

His mind was constantly recalling the properties of each material, as well as the content of the metal.

In his mind, he was constantly simulating the process of refining the heavy sword.

After dozens of simulations, Ye Lin still shook his head and sighed: "It seems that forging a heavy sword is not as simple as I imagined. ”

The combination of materials and the control of content are like thousands of secret recipes, each of which can affect the final product.

Even if he continued to deduce with his huge divine sense, he could not find a complete solution.

Ye Lin lightly touched these materials, and then a look of determination appeared on his face.

He played out one after another mysteries in his hands, and those materials were mobilized by him one by one.

With continuous familiarity, Ye Lin has been able to have a clear estimate of the content of these materials.

Ye Lin still uses the method of double quenching of water and fire.

He took out a hundred years of tungsten steel and weak water, and took out an axe from the mustard seed bag.

Without a hammer, Ye Lin could only use this sharp axe to strike on the back.

This axe is also extremely sharp, and it is a good magic weapon, and it can be used as a hammer.

The purity of 100-year-old tungsten steel is far from reaching the strength required by Ye Lin.

Therefore, in the first step, he must continuously quench the tungsten steel, and constantly use high temperature to improve the purity, until the sand steel is smelted one by one.

Ye Lin held an axe in one hand, and the Taiyin True Fire slowly burned the century-old tungsten steel from below.

When the temperature is extremely high, Ye Lin will use weak water to continuously cast, while watering, while annealing, to prevent tungsten steel from violent deformation.

At the same time, the back of the axe in his hand also repeatedly hit the tungsten steel at this moment.

Only by constantly beating tungsten steel can the purity of tungsten steel be raised to a very high degree.

The role of 100 steels is not only to improve purity, but also to make the steel content tend to be stable and uniform.

Ye Lin's mind kept recalling the dozens of simulation exercises, and in his hands, it was constantly changing, sometimes the temperature of the Taiyin True Fire rose violently, and sometimes the weak water added more.

Under the continuous tempering, sand particles gradually appeared in the steel.

When Ye Lin saw these shagangs, he did not appear to be happy, but had a serious face.

A hundred years of tungsten steel, after all, is only a hundred years, if it is changed to a thousand years, I am afraid that it will be able to play seventy-two refinements.

But now, Ye Lin can only do thirty refinements.

Despite this, a large piece of 100-year-old tungsten steel looks pitiful at this time.

He wanted to forge a sword that was both a heavy sword, but at the same time tough and sharp.

Such demanding requirements make the forging process extremely difficult.

If the sword is heavy, it will inevitably increase the content of the material, and the more the content, the more impurities.

If you want to purify, you need to have a complex process and enough control of the heat.

If the sword is sharp, it must be a light sword, and if it is a light sword, then his toughness will not be very stable.

As soon as Ye Lin thought about it, he already understood the complexity.

A truly good sword requires a lot of spirit and skillful craftsmanship to make.

Therefore, he just wanted to find a balance between these three points, which could not only ensure the sharpness of the sword, but also ensure that the sword was heavy enough, and at the same time had enough toughness.

If this sword can achieve this balance, then it is undoubtedly a good sword.

"Thirty refining !!"

Far from enough, Ye Lin's eyes showed a hint of determination.

In his hand, the vial of dragon marrow was poured into most of the shagang mixed with it.

Those shasand steels were rapidly fused in a state that was visible to the naked eye.

Ye Lin was short of breath, and immediately put the pine wind wood in his hand on the Taiyin True Fire and burned it.

The pine wood quickly turned into clumps of black charcoal.

After doing this, Ye Lin's movements did not stop, he poured the thousand-year-old Xuantie, Zhu Shi, and Iron Essence in his hand, as well as the liquid formed by the fusion of the Golden Bucket, the Loose Pattern Sword, and the King Kong Table, onto the sand steel.

This process is only dozens of breathing time, Ye Lin is multi-purpose, constantly consuming his mind to increase the speed of the technique to the extreme.

He exhaled deeply, this kind of solidification mixed with different materials, it was much more difficult to forge and purify.

If you want to achieve a hundred refinements, you must forge one and weigh one light, until the catties are not reduced.

The composition of 100-year-old tungsten steel is obviously not perfect.

But with the addition of these different materials, the solidification in front of him has reached a terrifying level.

The difficulty of refining has also increased greatly, which is also a pressure he has never felt before.

This solidification puts extremely high demands on the mastery of the flames, the force of the blow, and even the addition of weak water and dragon marrow.

As long as one of these links goes wrong, the final product is likely to be unsatisfactory.

Wiping the beads of sweat from his forehead, Ye Lin still didn't rush to build it.

Hundreds of processes kept coming to his mind.

The amount of water added, the amount of carbon added from the firing of pine wood, and the most important thing is the size of the flame.

Abruptly, Ye Lin seemed to have found a trick.

He seemed to have grasped something, and there was a slight smile on the corner of his mouth.

Rather than trying to find a method that doesn't even exist in the hundreds of methods, if I get the heat in place, the amount will change as the heat is added.

As it turned out, Ye Lin seemed to have a kind of enlightenment, and his mind immediately simulated the temperature of the flame, so as to calculate the ratio of materials required under each level of high temperature refining.

What kind of temperature can make this material reach the ultimate refining, the amount of impurities in the refining, as well as the timing and content of the addition, and even the instantaneous time change of minutes and minutes, Ye Lin did not ignore it.

This process has been extremely long.
