Lu Qingfeng has now cultivated to the peak of the Immortal True Realm, he knows very well in his heart that the more he gets to the back, the more difficult it is to break through, just breaking through the Immortal True Realm will cost him more than 10 million yuan of crystals, breaking through the back realm, the number of Yuan Crystals required is ten times and dozens of times higher than this, when he knows the wonderful use of the Divine Crystal Qiankun Palace, this concern will no longer exist.

At the time of the sect. Lu Qingfeng knew that Xiaoyao Town was a place where he didn't care about both, in his opinion. In a place like this, the order must be quite disordered, after going out to see it yesterday. He realized that it was completely the opposite of what he thought.

All of them seemed to be fate, but they encountered a sneak attack by the Great Elder of the Heavenly Cloud Sect of the Gong Shang Empire in the Misty Lake, which made him encounter Dongfang Yunfei after he was seriously injured, so that he could get the guidance of the Great Grandmaster on the Dan Dao, and the casting of the best magic weapon long sword was also settled.

If nothing happens, I am afraid that my trip to the small town will be nothing, thinking of this, I also want to thank the great elder for the sneak attack, all this qiē is thanks to him.

It's just that Lu Qingfeng doesn't understand that as a great elder of a super sect, why would he choose him to sneak attack, how could such a high-status person do such a sneak attack for a spiritual treasure.

As a true disciple of the Qingyun Sword Sect, Lu Qingfeng clearly knew that the golden robes worn by the elders of this sect and the swords they carried with them were all acquired spiritual treasures, and the Tianyun Sect was even stronger than the Qingyun Sword Sect, and it was impossible for their great elders to lack spiritual treasures. Lu Qingfeng felt that this matter was very strange, and when he saw this person in the future, even if he was fighting to the death, he had to ask the reason clearly before.

After cultivating in the Divine Crystal Qiankun Hall all night, the essence and spirit had reached the peak, and when he came out of it, Lu Qingfeng went directly to Ouyang Jian's backyard next door, and after arriving in the backyard, Ouyang Jian was already waiting there. Seeing Lu Qingfeng coming in, Ouyang Jian stood up and said, "Let's go, let's go to the Earth Fire Vein now." ”

Hearing the three words of the Earth Fire Vein, Lu Qingfeng was a little surprised in his heart, seeing Lu Qingfeng's expression, Ouyang Jian smiled: "Don't be surprised, when you get to the place, you will know everything." ”

After speaking, Ouyang Jian led the way in front, walked into the westernmost house on the north side, entered this room, and there was a one-meter-square stone slab on the ground in the middle, Ouyang Jian unlocked the prohibition on the stone slab, opened the stone slab and walked down.

Lu Qingfeng followed, and inside were stone steps extending down, and the walls on the side of the stone steps were inlaid with luminous crystals, so it was very bright, and the winding and deep stairs extended downward, Lu Qingfeng estimated that he had walked at least five thousand meters and had not yet reached the end, but the temperature in this small passage was getting higher and higher.

This completely subverted Lu Qingfeng's cognition, in Lu Qingfeng's view, it should be that the deeper it goes, the cooler it is. After walking for more than two hours, they finally saw the light in front, and then, the two of them arrived at a room with an area of more than 300 square meters, the whole room was red, made of rocks that Lu Qingfeng didn't know the name of, in the middle of the red stone house, there was an octagonal convex pattern of about ten square meters, which was carved with fine and complex lines, and in the center of this pattern, there was a round hole with the thickness of an arm, and the lines on the octagonal pattern converged towards this round hole.

Now the temperature of this red stone room, if it were replaced by an ordinary person, it might be melted in an instant, Ouyang Jian and Lu Qingfeng stood at the edge of this octagonal pattern.

Looking at Lu Qingfeng's puzzled look, Ouyang Jian said with a smile: "This pattern, called the Octagon Juyuan Array, transports the true yuan to the formation, and the small hole that converges to the center can ignite the ground fire, don't look at this Octagon Juyuan Array seems to be ordinary, but it has a great effect on the swordsmith, let me give you an analogy, you input one into the true yuan into this formation, and when you reach the small hole in the center, it is equivalent to the ten percent true yuan you excite, and you will understand when I say this." ”

Ouyang Jian turned around and pointed to a one-meter-sized golden tree stump placed next to the wall and a sledgehammer poked next to it: "Look at that metal pier and sledgehammer, they are all made of pure gold outside the universe. ”

Lu Qingfeng had seen the classics introducing metal materials, and of course he knew that these two metals were priceless.

Then, Ouyang Jian pointed to a box-like thing next to him and said: "Look at that vessel, it is an alloy made of a variety of extraterrestrial metals, the characteristic of this alloy is that it is not easy to deform, and the melting point is extremely high, its function is to pour the molten metal liquid into it, and the impurities in the metal will float on it, and then remove the magazine on it, this process must be repeated at least three times." ”

In the end, the two came to a pile of sand, and Ouyang Jian said, "This is the quicksand of the outer space. After speaking, he shook his hand, and a huge piece of metal fell to the ground: "This piece of metal is called wild pure aluminum, which is used to make a mold for casting a sword, and I will show you how to make a mold for you." ”

After speaking, Ouyang Jian came to the front of the Wild Pure Aluminum, the True Yuan gathered in the palm of his hand, and turned into a True Yuan Giant Sword more than two meters long, the True Yuan Giant Sword slowly approached this Wild Pure Aluminum, and gently cut it five centimeters away from the edge, and soon, a one-meter-wide and two-meter-long Wild Pure Aluminum Plate was cut down.

The True Yuan Giant Sword shrank to the size of a dagger, and cut it at this piece of Savage Pure Aluminum Plate, and in an instant, two Savage Pure Aluminum Plates fifty centimeters wide, five centimeters thick, and two meters long took shape.

The True Yuan dagger in Ouyang Jian's hand shrunk into a True Yuan carving knife, and it carved quickly on one of the plates, only to see the aluminum cutting flying around, flashing with silver light.

After a while, a sword-shaped dimple appeared on this board. Then, carved on another plate, the same sword-shaped grooves appeared on the other plate as on the first plate.

Ouyang Jian cut out a tiny round hole in the hilt of one of the plates, and Ouyang Jian took the two metal plates that were buckled together to the quicksand of the outer space, and buried the two metal plates that were buckled together in the sand, and only the tiny round hole was exposed.

After finishing this qiē, Ouyang Jian looked at Lu Qingfeng and said: "This is the whole process of making a mold, after purifying the molten metal, it is injected into the mold through that small hole. When the metal cools down and is taken out of the sand, it is only a complete sword blank, and finally it has to be constantly beaten, depicting the attack formation, and after doing this, the magic weapon long sword can be completely completed. ”

Lu Qingfeng nodded and said, "Senior Ouyang, the qiē you demonstrated just now has already been memorized by the juniors. ”

Ouyang Jian said: "Okay, I'll teach you the previous sword casting procedure below." The two of them came to the front of the Eight Directions Gathering Yuan Array, and Ouyang Jian stretched out his right hand and pressed a prominent place on the edge of the Eight Directions Gathering Yuan Array.

The true element was slowly injected into the array, only to see the light of the Eight Directions Gathering Yuan Array light up, and all the light converged to the position of the central round hole, and at the moment when the light reached the position of the round hole, a red flame erupted from the round hole, and continued to send the true element to the Gathering Yuan Array until the temperature of the flame was enough to melt the metal material.

Ouyang Jian quickly took out the seabed sinking silver, wrapped it in true yuan, and leaned towards the top of the earth fire, an hour later, the deep sea sinking silver had softened and deformed, and half an hour later, Ouyang Jian said to Lu Qingfeng: "Bring that vessel." ”

Lu Qingfeng quickly condensed a True Yuan big hand, directly grabbed the vessel containing the solution, and came to the side of the deep-sea sinking silver that was about to melt.

At this time, the deep sea sinking silver has begun to melt, under the control of Ouyang Jian's true yuan, the melted liquid keeps flowing into this vessel containing the solution, with the continuous heating, the speed of the deep sea sinking silver melting is getting faster and faster, and when all the solutions enter the vessel, Lu Qingfeng quickly controls the true yuan big hand to remove the impurities on it.

Next, Ouyang Jian took out the secret copper outside the sky, melted it and injected it into this vessel as well, and then melted the Xingchen Iron in the same way, all of which were removed by Lu Qingfeng, and now, the three metal liquids are in the same container, because of the different specific gravity, they are at different levels, and they have not yet fused with each other bit by bit.

I saw Ouyang Jian quickly take out an object, and said at the same time: "This is fusion gangue, a kind of stone that can make metals of different specific gravity fuse with each other. After speaking, he threw himself into the solution vessel, and at the moment when the fusion gangue entered the solution vessel, he saw three metal solutions constantly churning up and down in the vessel, and white bubbles kept emerging.

After a few minutes, the metal liquid stabilizes, the bubbles no longer come out, the fused metal quickly cools down, and then the fast fused metal is poured out, sent to the flame to continue the above process, and so on three times, a pure metal fusion liquid is obtained.

Ouyang Jian quickly turned off the fire, and the solution vessel came to the quicksand mold, and slowly injected the fused metal liquid into the mold against the small hole on the mold, and when the metal solution in the solution vessel was poured out, the metal liquid had already spread out of the small hole in the mold.

Two hours later, picking up the quicksand of the space, I saw a sword blank slightly larger than the expected finished sword appeared in front of the two, Ouyang Jian said: "Use this hammer to keep beating this sword on this pier until the size meets your requirements, and at the same time, you pay attention to one point, the landing point of the second hammer should be pressed half of the landing point of the first hammer, and the sword blank will be heated with the real fire in the body after cooling, and then continue to beat." ”

According to what Ouyang Jian said, Lu Qingfeng began to beat the sword blank non-stop, heated it after cooling, and then beaten, so repeated operations, Lu Qingfeng himself didn't know how many times he heated and beaten, until all aspects of the long sword met his requirements.

Ouyang Jian was guiding on the side, seeing that Lu Qingfeng stopped, took the long sword, looked at it carefully, and said: "When beating, the strength must be even, and I will depict the attack formation below, the formation of the best magic weapon is ninety-nine eighty-one, the high-grade magic weapon is seventy-seven forty-nine attack formations, and so on for the middle-grade and low-grade ones."

Ouyang Jian held a Zhenyuan carving knife in his hand, carefully carving the attack formation on the sword's body, Lu Qingfeng carefully observed on the side, five days later, Ouyang Jian's movements stopped, and his spirit was obviously a little sluggish, this is because the carving attack formation consumes a lot of mental power.

Lu Qingfeng reached out and picked up a towel next to him, and after wiping the sweat stains on Ouyang Jian's face, Ouyang Jian said, "Qingfeng, you can give the sword a name." ”

Lu Qingfeng looked at this sword, the silver-white sword body was mixed with red like blood, as if these reds were absorbed into the body by the long sword, so Lu Qingfeng opened his mouth and said, "It's called the Blood Drinking Sword." ”

Ouyang Jian held the Zhenyuan carving knife in his hand, and at the position of the sword body close to the hilt, he quickly carved the two beautiful seal characters of 'Drinking Blood'.

Subsequently, Lu Qingfeng asked Ouyang Jian to make a scabbard with the skin of the giant python, put the blood-drinking sword into the sheath, tightly close it, press the spring switch on the scabbard, only to hear a crisp sword sound, the blood-drinking sword automatically came out of the sheath, emitting a faint silver-white light, trying to enter a trace of true yuan, and suddenly the light was bright, and a glance would make people blind for a short time.
