Ever since that day when the One Page Book's plan was ruined and the One Page Book failed to capture the evil and filthy atmosphere of the human world, Lu Yan had been on guard against whether the One Page Book would sneak up on the human world.

It's just that several days have passed, and the book has not taken any action on the human world.

This made Lu Yan realize that a one-page book would not take any retaliatory action against the human world in a short period of time.

This also made him feel a little more relaxed.

Because no medicinal materials have been delivered recently, Lu Yan's research on refining medicine was also forced to stop.

At this moment, Lu Yan suddenly thought of the weapon refining album he had obtained through a lottery draw before.

As more and more true immortals emerge from the human race, the magical weapons and magic weapons in their hands become more and more rare.

He could take advantage of the current opportunity to study weapon refining, and then refine a batch of magic weapons to enhance the combat effectiveness of the new true immortals.

Lu Yan had learned the skills of blacksmithing and forging weapons from Xie Zhuoyan before, so he had some basic skills.

It cannot be said that I was clueless when studying this weapon refining atlas.

"Tool refining also starts with refining the materials, but instead of hammering them with a hammer, you use a furnace."

Lu Yan looked at the introduction to the refining in the refining atlas and decisively took out the Bagua furnace and placed it in the open space of the room.

This Bagua furnace has six dings of divine fire, one of the four heavenly fires, which is excellent whether it is used to refine elixirs or to refine weapons.

You know, Taishang Laojun not only uses this Bagua furnace to make elixirs.

Treasures such as the Ruyi Golden Cudgel and the Diamond Cudgel were also refined from the Bagua Furnace.

Therefore, Lu Yan's use of the Bagua Furnace to study the lowest level materials is simply a injustice to the Bagua Furnace.

It is said that reading thousands of books is not as good as traveling thousands of miles.

After Lu Yan studied the weapon-refining atlas for a while, he decisively asked Xie Zhuoyan to go outside and retrieve a large amount of iron for him.

Lu Yan directly used his immortal power to perform the initial purification of these iron nuggets. Tens of thousands of kilograms of iron nuggets were finally refined into less than ten kilograms of iron essence.

These ten kilograms of iron essence are then refined in the Bagua furnace to finally obtain iron crystals, which can be used to refine magic weapons!

"It's not enough, I need more iron blocks."

Lu Yan turned to Xie Zhuoyan and said.

Xie Zhuoyan did not hesitate and flew away directly.

Lu Yan also left the room and went to an open-air place outside the city.

It's always more comfortable to do this kind of thing outside than in the room.

This time it took half a day for Xie Zhuoyan to return to Songhai City.

This time she went out and brought back tens of millions of kilograms of iron for Lu Yan!

She visited the Qin, Tang, Song and Ming dynasties before collecting these iron blocks.

Otherwise, Da Qin alone would not be able to meet Lu Yan's needs.

Xie Zhuoyan piled a huge number of iron blocks in front of Lu Yan. The iron blocks were piled together like a hill, denting the ground!

She said to Lu Yan: "This is the iron output of the four dynasties for almost a year. It should be enough for you."

Lu Yan looked at the iron mountain in front of him and said with a smile: "It should be enough to refine several magic weapons."

Xie Zhuoyan was a little surprised when he heard Lu Yan's answer and asked: "With so many iron blocks, how many magic weapons can only be refined?"

Lu Yan nodded and said: "Although the magic weapon is the lowest treasure, it is not an ordinary thing. Iron crystal is just the lowest material for refining the magic weapon. It can only be used for me to practice my skills."

"If you want to refine a magical weapon or magic weapon with better quality, you need better materials."

As he spoke, Lu Yan raised his hand and injected a stream of immortal power into the iron mountain in front of him.

As he poured a steady stream of immortal power into Iron Mountain, the volume of Iron Mountain was slowly shrinking.

The waste residue in the iron blocks was refined and turned into thick black smoke flying toward the sky, turning the sky gray.

Lu Yan looked up at the sky and whispered, "Is this considered industrial pollution?"

It seems that he will have to think of a more environmentally friendly method to purify these materials in the future.

After about a stick of incense, the tens of millions of kilograms of iron turned into just over a thousand kilograms of iron essence.

Seeing that the hundred-foot-high iron mountain turned into such a small lump of iron, Xie Zhuoyan couldn't help but smile bitterly and said: "At this consumption, the entire human world's iron production in a year will not be able to refine many magic weapons.

"

Lu Yan nodded slightly and said, "So we need to find better materials."

As he spoke, Lu Yan had already thrown all the iron spirits in front of him into the Bagua furnace.

He wants to start purifying.

The purification process is not complicated.

Lu Yan's proficiency in controlling fire when refining alchemy is also useful at this time.

In just a few moments, more than a thousand kilograms of iron essence was purified into iron crystals.

At this time, the weight was only over thirty kilograms.

Lu Yan took out more than thirty kilograms of iron crystals from the Bagua furnace, and then said to Xie Zhuoyan: "It's a little more than I imagined. Maybe I can refine ten magic weapons without failure."

Xie Zhuoyan looked at the pure black iron crystal in Lu Yan's hand, which looked like a black crystal and was very crystal clear, and said with some surprise: "This thing is much more beautiful than I imagined."

Lu Yan smiled slightly and said: "If you use this kind of thing to make jewelry, it will look very good, but it is a bit wasteful."

As he spoke, Lu Yan cut the iron crystal in his hand into neat small pieces.

Each small piece is about the size of a palm and weighs three kilograms.

He looked through the weapon forging album placed aside, selected a sword from it, and said: "I used to forge swords when I was blacksmithing. Today I will forge a flying sword weapon first."

Xie Zhuoyan sat aside and watched Lu Yan's operations quietly.

Just like when Lu Yan tried to make alchemy, she was looking forward to Lu Yan's next performance.

Lu Yan threw the iron crystal in his hand into the Bagua furnace, then activated the six dings of divine fire in the Bagua furnace to refine the iron crystal into water, and then injected his spiritual thoughts to condense the iron crystal that turned into water into flying water.

The shape of a sword.

The whole process is not complicated.

Lu Yan completed this step easily.

But this is just the beginning. After refining the prototype of the flying sword, it needs to be processed carefully.

Compared with the previous operation, this fine processing process seems relatively cumbersome.

Lu Yan needs to engrave a fairy formation on the surface of the flying sword.

In this way, when the monk activates the flying sword, he can inject immortal power into the flying sword to enhance the power of the flying sword.

In addition to the fairy formation, Lu Yan also engraved the acceleration formation on the other side of the flying sword.

This formation can make the flying sword fly faster.

In an instant, the enemy's head can be taken from thousands of miles away.

After inscribing these two formations, Lu Yan stopped engraving other formations on the flying sword.

This is because the iron crystal's endurance is limited, and the two formations are basically the limit.

After all the two formations were engraved on the flying sword, Lu Yan activated the Six Ding Divine Fire again to completely integrate the two formations into the flying sword.

After all this was done, Lu Yan opened the Bagua furnace.

He raised his hand and waved, and the flying sword flew out of the Bagua furnace and landed in his palm.

Lu Yan looked at the flying sword, which was no more than a foot long, completely black and crystal clear, and had no distinctive appearance. He turned to Xie Zhuoyan and said, "It's done."

Hearing this, Xie Zhuoyan came over and took the flying sword from Lu Yan's hand.

She looked at the flying sword with curious eyes and tried to activate the flying sword.

Whoosh!

The flying sword flew away from Xie Zhuoyan's hand like a wind, and was thousands of miles away in the blink of an eye.

puff!

The flying sword instantly chopped up a huge boulder, then returned from thousands of miles away and fell into Xie Zhuoyan's hands.

The whole process only takes two breaths, which can be said to be quite fast.

Xie Zhuoyan played with the flying sword in his hand and said with a smile: "This flying sword feels pretty good, I will accept it."

Lu Yan heard this and said, "You have done a good job in collecting iron pieces for me. The first magic weapon I refined in my life will be given to you as a gift. You can also give it a name."

Xie Zhuoyan looked at the flying sword in his hand, thought for a moment, and then said, "Just call me Xiao Lu Feijian."

When Lu Yan heard this name, he immediately couldn't laugh or cry, and said, "As long as you are happy."

Xie Zhuoyan asked curiously: "When did you learn to engrave formations?"

Lu Yan replied: "The formations I have engraved are very simple, and their power is relatively average. They are nothing."

Lu Yan had seen many formation diagrams when he was in the fairy world.

The most basic formations, such as the Fairy Spirit Formation and the Acceleration Formation, can be learned at a glance as long as a person with strong spiritual will can do so.

There is no difficulty when engraving.

If not for this, Lu Yan would not have been able to try to refine the magic weapon.

After Xie Zhuoyan heard Lu Yan's explanation, he didn't ask any more questions and continued to play with the little Lu Feijian.

Lu Yan, on the other hand, struck while the iron was hot and refined all the remaining nine iron crystals into magical weapons.

Five of the magic weapons are offensive and four are defensive.

He plans to place these nine magic weapons in Fenbaoyan. Anyone who is promoted to a true immortal can go to Fenbaoyan to choose a favorite magic weapon for himself.
