When Senior Brother Cheng saw that everyone had arrived, he stopped chatting with Qian Chao, stood up, struck with both palms, and attracted the attention of all the disciples in the courtyard with a "snap".

"In the next surname Cheng, Cheng Qiantang is, in the future, you can call me Senior Brother Cheng, and I will be ordered by the master, and the alchemy skills of your junior brothers and sisters will be taught by me in the future."

As he spoke, Senior Brother Cheng Qiantang paced and looked at everyone, remembering the faces that were still unfamiliar in his heart.

"Today's first lecture, what I said will not be too much, but it is very important, and I will point out to you a path in the cultivation of this alchemy, so please listen to your junior brothers and sisters attentively."

Speaking of this, Senior Brother Cheng returned to the wooden case and took out a storage bag and put it on it.

"You've all received a sword when you got started,"

After Senior Brother Cheng finished speaking, he took out a long sword with a sheath from the storage bag, and with a "cang" sound, he pulled out the blade and showed the crystal sharp sword body to the disciples.

"This one in my hand is the same as you have received."

As he spoke, he placed the blade of the sword horizontally in front of him, and interlocked the thumb and index finger of his left hand to flick the blade of the sword, and the sword trembled and made a buzzing sound.

"If you say that this sword is good, it is okay."

After saying this, Senior Brother Cheng took out a wolf rammed heavy stone from the storage bag, and the brown and gray stone was suspended and landed on the side of the bookcase under Senior Brother Cheng's spiritual power, and there was a muffled sound when it fell, obviously this stone was extremely heavy.

"Look!"

I saw that Senior Brother Cheng threw the long sword in his hand, and the sword was hanging but not falling, at this time, Senior Brother Cheng's right hand and index finger merged into a sword trick, and said the word "Zhong" to the big stone finger.

The long sword suddenly flashed like a meteor and pierced the boulder, and the sound of "bang" was very piercing, and then the sword left only a hilt outside the stone, and the entire sword body was not even in the boulder.

"Wow!" Many of the disciples present were all stunned when they saw it, they didn't expect the long sword given by the master to be so sharp, and Qian Chao was also stunned, only then did he know that the long sword in his storage bag was actually used like this, but he thought that the sword should be held in his hand to slash and kill when used.

Before the senior brother's demonstration was over, he hooked his finger at the long sword that had sunk into the stone, and the sword "clicked" out like a strange snake. Senior Brother Cheng looked at the boulder, walked over and scratched the stone twice with a finger, and when he walked away, the long sword hanging in the air came forward, as if it was held by a thick hand, and slashed twice at the boulder, and slashed at the place where Senior Brother Cheng's finger was drawn, "Bang! "Bang!" Two sparks burst out, and they actually cut the big stone into three pieces along the scratched place, and the place where the blade of the sword passed was abnormally flat, and you could see the spots inside the big stone.

And the sword was unscathed, unharmed!

Senior Brother Cheng used the Imperial Technique to hang all three pieces of the big stone for the disciples to watch.

"How, this sword is pretty sharp, isn't it?"

After putting the three stones back on the ground, Senior Brother Cheng asked the disciples.

All the disciples nodded one after another, excited in their hearts, and secretly said that the master had given him such a treasure!

Senior Brother Cheng smiled when he saw it, then took out the second long sword from the storage bag, grabbed it in his hand and said to everyone:

"This one is a sword that I refined many years ago, not long after I first entered the sect like you, under the guidance of my senior brother at that time."

As he spoke, he drew the sword and showed it to the people.

This second sword was bland, much less splendor than the first sword.

"What do you think would happen if two swords struck each other?"

This...... Everyone didn't know what Senior Brother Cheng meant, but if the blades of the two swords collided, it would inevitably be either broken or both would be lost, or one would be uninjured but the other would be cut open a gap, and there seemed to be no other result. But it seems that the shiny one has a bigger chance of winning.

When everyone thought about this, they saw Senior Brother Cheng's hands moving together, and saw that the two swords were hanging in the air, slashing each other like two people fighting, and the sound of "dang" shocked everyone again!

I saw that the long sword that Senior Brother Cheng refined himself actually cut off the first sword, and after the cut, the two swords hung there quietly, even the broken sword body never fell to the ground, just hanging, let everyone watch carefully.

"This ......!" Everyone was really stunned at this moment, the sword that was extremely sharp just now was cut off at once, and that sword could easily cut through a big stone, and it was broken all at once!

Looking at the other sword, at least it looked intact, it was the first sword that Senior Brother Cheng had refined like himself, could it be so sharp?

Seeing that everyone was in a daze, Senior Brother Cheng smiled slightly, and led the long sword he had refined with one hand to slash towards the broken sword again.

Although the broken sword was cut into several pieces, it still maintained the shape of a sword, hanging in the air without falling, allowing everyone present to look at it carefully in shock.

"Isn't it a little distressing?" Senior Brother Cheng said with a smile, he could see it from the faces of these junior brothers and sisters.

"It's okay, although this sword was cut off by me, this broken sword can still be reforged, as long as you put more effort into it, I don't know how much better it can be after reforging."

"But," Senior Brother Cheng summoned the sword he had refined into his hand, stroked the sword body and asked, "Do you know why these two swords are so different?"

This is exactly what the disciples are thinking in their hearts, and when they saw Senior Brother Cheng asking like this, they couldn't help but talk about it.

"Okay," after listening to it for a while, Senior Brother Cheng interrupted the discussion of the disciples, "I also listened to what you just said, and I can tell you with great certainty that the materials used in the refining of these two swords are the same, and it can even be said that the materials used in the refining of this one by myself are even less." ”

Seeing that these junior brothers and sisters couldn't guess anymore, Senior Brother Cheng opened his mouth and continued:

"The reason why my own sword can easily cut off that one is very simple, it is because my sword is only one more rune engraved on the sword than the broken sword when refining, the sword in your hand is only engraved with three runes on the sword body when refining, and I refine it myself, there are four runes on the sword body, you have already received the scriptures of this rune learning, I don't know if you have read it, but I won't talk about those today."

"The mystery of this refining weapon can be described as infinite, the difference of a rune is just that it can be so far different between two swords. To tell you the truth, I don't use this four-rune spirit sword for a long time, and if the spirit sword I use now is to slash this sword, hum, it will be even easier than just now. If you are reluctant to use spirit stones to exchange with others, then you must learn the art of refining with your heart, as long as you are willing to work hard and put your mind into it, you will be able to refine the spirit weapon that you like. ”

"Well, besides, you must not think that the spirit sword issued to you by the master is vulnerable, I can say bluntly that the spirit sword in your hand is the lowest level among the refining weapons, because with your cultivation, you can only use such a spirit weapon now. However, this kind of spirit sword, even if your cultivation reaches the third layer of refining weapons, going out to do things for the Honor Academy, and killing those demon beasts encountered outside the sect is almost enough to deal with. ”

After saying this, Senior Brother Cheng stopped, let the group of junior brothers and sisters taste it for a while, and then said:

"As I said just now, the material used for refining these two swords is the same, do you know what material it is?"

Everyone shook their heads and waited for Senior Brother Cheng to continue.

I saw Senior Brother Cheng's right hand move, and one of the stones that had been cut into three pieces just now slowly floated up and moved in front of him.

"Could it be that our sword is actually made of this stone?" At this time, some of the many disciples began to talk about it again.

"I guess you all thought this was an ordinary stone, but in fact, this is a rough piece of chlorite ore, and its hardness is far greater than ordinary stone, you see!"

After Senior Brother Cheng finished speaking, his right hand was aimed at the stone, and his five fingers were slightly bent. I saw that the stone began to tremble, and with a crackling sound came, the stone first began to split into two by a crack, cracked into two, and then each began to have countless cracks to continue to crack, but none of the stones burst out, and the pile of scattered stones were hanging in front of Senior Brother Cheng's palm, still cracking.

In the end, in less than a cup of tea, the stone was completely shattered and turned into a ball of gravel hanging in front of Senior Brother Cheng's palm.

Qian Chao was the closest, and he saw it really clearly, and three words flashed in his heart: Imperial Technique.

Senior Brother Cheng waved his right hand lightly, and the mass of gravel began to rotate, and when it stopped after a few turns, the top point of the gravel was different from the large mass below, the color of the top point was much darker than the bottom one, and the one below seemed to be ordinary gravel.

Senior Brother Cheng pointed to the darker grit on the top and said:

"Look, the top of this is the green copper, the green copper used in our refining is naturally not the kind used to mint money in the world, the mortal gold and iron can't withstand the imprinting of the runes when refining the weapon, I'm afraid that half of the runes are not printed, and the mortal iron will collapse."

"In fact, there are a lot of impurities in the green copper above, and there is still a small amount of green copper mixed in the following, if you want to completely refine the green copper in a piece of ore, you need to use the art of fire alchemy, which is why you all got a copy of "Fire Control Technique", but only for refining tools, fire control skills do not need to be refined, just enough."

Saying that, Senior Brother Cheng let the ball of gravel fall on the wooden case.

"Just now I broke this ore and turned it into a pile of sand, and before I controlled the spirit sword, I used the Imperial Technique, which is the most important thing for us who practice refining."

Senior Brother Cheng picked up the hilt of the broken sword and said, "If you have cultivated the Imperial Artifact Technique, the same spiritual weapon will naturally be more powerful in your hands. After saying this, I saw that the fragments of the broken sword on the wooden case flew out one by one "clanging" and continued to be spliced at the hilt of the sword, and with the last sword tip spelled up, the broken sword turned out to be a complete sword again, but the previous brilliance was long gone.

"It's like the same weapon, people with more strength will naturally be more powerful when wielding it than people with less strength!"

Senior Brother Cheng held the spliced sword and made a posture of drawing the sword out of the sheath, who knew that as soon as he pulled out the sword, the sword he had refined himself on the case was also pulled out with a "cang" sound, hanging above everyone.

I saw Senior Brother Cheng's body turning, dancing a few sword styles, the long sword in his hand that had been broken into several pieces or stabbing or teasing or chopping or chopping, and the spirit sword above everyone seemed to be held and danced by a transparent person at the same time, and there was no difference between the sword style used by Senior Brother Cheng, only to see a cloud of sword light floating around. It's just that Senior Brother Cheng was silent when he danced, but when the sword above everyone danced, there was a sword roar like a dragon roaring and a tiger's roar.

After the dance, Senior Brother Cheng stretched out his left hand, and the two scabbards on the wooden case flew up at the same time, one to Senior Brother Cheng's left hand, and the other to the sword above everyone.

With a "click", both swords were sheathed at the same time.

After the two swords were placed on the wooden table, seeing the surprise in everyone's eyes, Senior Brother Cheng pulled out the broken sword, but only pulled out a piece of the hilt, and everyone believed that the sword was still broken.

"This imperial art is still an important means for us to refine weapons, although it can't be said that the better the imperial technique, the better the spirit weapon refined, but if the imperial object technique is mediocre, it is difficult to refine a high-grade spiritual weapon, ah, there are a few pieces of green copper here, you can take a look first."

Senior Brother Cheng took out a few dark green ingots from the storage bag, which looked not much different from the color of the patina.

Senior Brother Cheng pointed to the pile of gravel on top of the wooden case and said:

"This green copper is refined from here, you want to practice this alchemy, but not at the beginning to give you materials, tell you the method, and then let you go to refine, the first thing you have to learn is to prepare materials, the master will not give you green copper ingots for you to use, to give you are green copper ore, if you want to refine the weapon, you have to refine this green copper ingot yourself, this step is called making materials, if the materials made are inferior, it is impossible to use it to refine the high-grade spiritual weapons, this material is used in the art of resistance and fire control."

Speaking of this, I didn't see how Senior Brother Cheng moved, the pile of gravel on the wooden case floated up again, began to rotate, faster and faster, rustling on the wooden case, it became tighter and tighter, thinner and longer, and finally became a straight "sand stick", which kept dancing under the control of Senior Brother Cheng's physical arts, and not a single grain of gravel was thrown out.

"I think you have all heard that the Nine Xuanmen of the Five Spirits Sect is the door of refining, and all the disciples in the door have one or two hands of refining, in fact, those are just rumors, among our nine Xuan, not to mention one out of ten or two who are really proficient in refining, even if it is one hundred and two, I am afraid that it will not be able to reach it, although I will talk about this alchemy for you, but I am also constantly practicing hard and studying, and the more I learn, the more I feel that this alchemy is broad and profound."

After saying this, I saw that the two ends of the previous "sand stick" were bent together, and turned into a perfect round "sand ring", the "sand ring" began to rotate, looking like a big "sand ball", but as the "sand ball" gradually became smaller, it changed from a hollow sand ball to a solid sand ball, and finally fell on the wooden case, and "dongdong" bounced a few times, and kept rotating in the center of the wooden case.

"Some people also say that there are two sects in the Five Spirits Sect that can earn spirit stones, one is to go to Qixia Mountain to cultivate the alchemy technique, and the elixir that is refined will naturally have monks rushing to buy the spirit stones. The other is to go to Jiuxuan to learn this alchemy technique, and the superior spiritual weapon is even more popular among the monks. This is true, but I want to tell you that we don't care about Qixia Mountain, at least there are very few of us Jiuxuan who can really earn spirit stones by refining weapons, and you will know this in the future. You must know that there are also disciples of the Nine Xuan Qi Refining who have higher cultivation levels in the third layer of Qi refining, as long as there is no foundation, almost everyone has to go to the Worship Academy to be sent to do things, for what, isn't it that after the things are done, they can get a few more spirit stones? How can it be as simple as the rumors say, well, don't hide it from you, I told you about this alchemy technique, it is also a send, but it is just a dispatch from within the door, and in the end, there is also a sum of spirit stones in my account, if I can earn spirit stones by refining spirit weapons, will I still bother talking here? ”

After saying that, Senior Brother Cheng tapped on the rotating sand ball, and the sand ball suddenly stopped, and then dispersed again into a pile of gravel.

"Tell you brothers and sisters this, just want you to go to that vain heart, don't wait until you are discouraged and disappointed in the future, in fact, even if you practice other methods in the door, everything is difficult at the beginning, this difficulty of refining weapons starts with this imperial art, you also see the high wall behind you, there is the hall of the door of the instrument, which is the place where the special material refining is located, but if you want to enter, your imperial art at least has to be looked at by me, otherwise you are not qualified to enter. A month later, I'll still be here, show me how well you have cultivated the Imperial Arts, and if you are qualified, I will take them to the courtyard on the other side of the wall to continue teaching, and if you are not enough, you will continue to work on the Imperial Arts. This practice is to sail against the current, and if you don't advance, you will retreat, and I hope that all of you will keep it in mind. ”

After speaking, Senior Brother Cheng glanced at everyone, and saw that many people had a look of fear on their faces, and couldn't help but smile slightly, but the little junior brother surnamed Qian who sat closest became more and more eager, and then he thought that this Senior Brother Qian had been staring at him since he started speaking, for fear of hearing one less word, and now he was looking at the pile of gravel on the wooden case carefully. Well, I don't know how far this Senior Brother Qian can go on this refining road.

"Okay, I'll explain the magic to you, it is estimated that someone should have learned it by themselves, this magic is not difficult to learn, but the difficulty is in mastery, after I finish speaking, it is time for you to work hard. For the next month, I would be here every day of the day, and I would come here if I had any questions. ”
