Su Chen spent three years breaking through the small bottleneck in the middle stage of the Golden Pill, and did not use spiritual medicines such as "mysterious spirit fruit" to hit the bottleneck, but instead broke through this small barrier through his own years of accumulation.

He found that after using the mysterious spirit fruit many times, it would have a "anti-drug reaction" like taking the same spiritual pill for a long time. The more you take, the more the effect of the elixir will decline. You need to change the types of elixirs frequently to avoid anti-drug reactions.

Now he is in the middle stage of the Golden Pill, and the effect of taking this spiritual fruit is like the ordinary third-level great vitality pill, which is much worse than before. Therefore, he also tried to avoid taking the mysterious spiritual fruit again.

Su Chen has been practicing in the multi-mountain fairy city where the Lingdao Alliance is located for nearly three years.

As the three-year Taoist meeting is about to be held in a few months, the fairy city is becoming more and more lively. Many Jindan monks rushed to Duoshan Fairy City in advance to make friends from all walks of life, preparing to participate in this new Taoist meeting.

Su Chen is quite looking forward to this. He should be able to meet Annu, Wu Qiao, and Mr. Lu in the future.

However, there are still months of free time.

Su Chen thought that he had reached the state of being a master of weapon refining and had achieved a little success in weapon refining skills, and he should also refine a few handy best offensive and defense magic weapons for his human body.

Attack magic weapons do not have good top-quality materials for the time being and cannot be refined.

But he thought of a good thing in his defensive magic weapon, and he had enough raw materials to use.

"Mstrian material!"

"The most powerful magic-proof material in the Immortal Cultivation World in China. Any armor can significantly enhance its resistance to various magical magic after adding mitral to any armor."

"If you can refine a set of mitral armor, it will greatly weaken the killing effect of enemy methods and techniques, and it will be difficult to damage water and fire, and all methods will not be invaded!"

When Su Chen thought of this, he couldn't help but feel excited.

He searched for his storage bag and found five hundred kilograms of mitril silver ore.

He had these mitsilver ore as early as the foundation-building realm, but this thing was too rare in the immortal cultivation world. Even a few kilograms of mits of mitsilver ore would covet it. He kept it unused and did not dare to take it out and entrust others to refine weapons.

Now that he mastered the art of refining, he could refine it himself without the need for a dummy hand. In addition, he was already a Jindan monk and needed such a top-level magic defense armor, so it was time to take it out to refine the artifact.

There are two steps to refining mitral silver, one is “purification” and the other is “smelting”.

The first step of refining the tool is to "purify" the original ore.

There is a lot of slag in the original ore and cannot be used directly. Any ore must be "purified" through the first process. Remove the stone and various slags in the ore and extract the pure ore. Otherwise, the properties will be messy and the quality will be poor and cannot be used at all.

The higher the purity, the higher the grade.

First-level low-grade black iron and first-level high-grade black iron are both extracts of thousand-year-old black iron ore, but their purity is different, and the price is several grades different.

The most common weapon refining method, "high temperature fire burning and water invasion", cannot refine these mitril ore. When encountering various spiritual energy such as water and fire, mitril ore will force them to avoid it automatically.

However, this problem has long been solved by Su Chen using a special method.

He used the large group of Misilian Spirit-eating Flying Ants from the Foundation Building Realm to eat the 500 kilograms of Misilian raw ore, and then they pulled out the separated and purified Misilian hunch. Rubbed off a layer of thick residue outside, and exposed a small mitral particle that had shrunk more than ten times.

This repeated dozens of times, continuously improving the purity of Misin silver, and finally turned into dozens of kilograms of high-purity Misin silver. Its quality is as high as the fourth level and belongs to the Nascent Soul-level refining material.

Each of these small mitril silver particles with strong magic properties exudes mysterious and gorgeous mitril silver light. It is extremely purity and has a very soft texture, so it can be shaped at will.

Su Chen didn't know what kind of weapon refining method he used to purify the spirit-eating flying ants.

He searched almost all the artifact refining classics that he could find, and there was no relevant record of the spirit-eating flying ants purifying minerals. Obviously, it was either an undiscovered technique or a secret secret technique that was secretly unrecognizable.

Next, the second step in refining the Misilan magic weapon is to "smel" the tool.

Mithril has the attribute of magic, but its texture is too soft and not strong enough to resist the slashing of swords. Mithril and other hard "gold and iron materials" must be melted into one to act as magic tools.

Of course, there is another simpler method, which is to apply a mitsilver coating on the surface of the magic device, which is much less difficult, and can also enhance the magic property of the magic device.

Be sure to ensure that the Miltese coating is not destroyed, as Miltese will fail if it is destroyed.

When cultivators fight, they often damage magic weapons. Therefore, this method is tricky, but it is not reliable.

The best way is to melt pure mitral and metal into one and refine it into an armored magic weapon. Even if it is damaged, it will not reduce its magic effect.

However, ordinary weapon refining techniques such as blazing flames obviously do not work.

Su Chen tried to use special ice scorching techniques to create dozens of ice crystals of ten feet in size and gather many sun fires to smel.

The power of the true fire condensed by each ten-foot ice crystal is focused on one point, and the firepower is comparable to the full casting of a late-stage Jindan monk.

As many as dozens or hundreds of giant ice crystals, such a fierce sun true fire, focused on a square inch, its power is even comparable to that of a Nascent Soul cultivator's Samadhi True Fire. Even the intact fourth-level defensive armor magic weapon will be burned through in an instant.

Su Chen was surprised to find that the high-temperature beam condensed by the sun's true fire shone on pure mites silver, and a slight protective film was formed on the surface of them, which still could not melt it.

Mithril can even deactivate high-temperature beams, which is shocking and incredible

Su Chen thought for a long time and tried to use many of the refining methods recorded in the refining books, but still didn't expect any way to melt these pure mitral silver.

He had to go to Tianbaozhai and ask Mr. Wei for advice from the weapon refining master.

Mr. Wei is a master of weapon refining for hundreds of years in the Duoshan Immortal City. He has rich experience. Although he is extremely low-key, he rarely takes orders when he opens a Tianbaozhai Weapon Refining Pavilion, but his weapon refining skills are recognized as the best. He is a top weapon refining master in the entire East China Sea Immortal Cultivation World and is highly respected by many Jindan monks.

"Mstr.?"

Mr. Wei was shocked when he heard this.

He knew that Su Chen had recently lived in seclusion in the fairy city and specialized in the art of refining weapons.

Su Chen is a big customer of Tianbaozhai. He has entrusted him to refine many top-quality magic weapons, one of which is the fourth-level top-quality blood coral halberd.

Mr. Wei was so strict that he would not mention this matter to outsiders.

But it does not mean that he turned a blind eye to the outside world. He also heard of a Baibu demon king in the East Sea Monster Realm. It is said that a fourth-level blood coral war halberd in his hand had been killed in the Demon Emperor Palace and cut off the heads of several Golden Pill Dragon Cultivators. He was extremely powerful.

The Blood Coral Battle Halberd with a grade of up to level 4 is probably just one in the world.

Mr. Wei didn't know why the top-quality blood halberd customized by Su Chen fell into the hands of the Baibu Demon King.

He also felt quite mysterious about Su Chen, the "identity" of the Golden Pill Cultivator of Penglai Immortal Sect, but he never asked about it.

In recent years, Su Chen has lived in seclusion and learned weapon refining techniques. He occasionally gives advice to Su Chen, the "weapon refining junior".

He didn't expect that Su Chen would be interested in the mitril silver materials.

"Misin silver material, this is the peak of weapon refining. "Secret Gold, Misin silver, Secret Copper, and Secret Iron" is the most difficult four major weapon refining materials. Their attributes are completely different, but they are all extreme.

The material of Mithril can be obtained occasionally in the deep trench in the East China Sea, but the quantity is extremely rare. Just add a small amount of Mithril to a magic weapon to greatly increase the magic property by 20 to 30%. Do you have Mithril?"

Old Dao Wei.

Su Chen couldn't help but explain and smiled, "I found a little mitr silver in the mine track in the northern bitter cold plateau. Then he thought about it and used it to refine it into a magic weapon."
