"Now there are steel swords and cast iron swords, which spirit sword do you choose to forge?" Mo Xian asked, looking at the various materials spread out on the table.

"What's the difference?" Yun Yu asked, carefully preparing all the materials that Mo Xian said, not afraid of wealth, but afraid of insufficient materials at the critical moment of forging, so it was somewhat worthless to give up all the previous efforts.

"The steel sword is the mainstream spiritual weapon, and the second-grade spiritual weapon is the Liyu sword, Longquan sword, etc., if the cast iron sword is used as the material, it is a forging knife system, such as the ghost tooth knife, the spirit flame knife, etc., you have to choose. Mo Xian looked at Yun Yu's curious expression, was quite satisfied in his heart, and said.

"Is there anything about the blue water and green bamboo?" Yun Yu then asked.

"Of course, but after reaching the third-rank forging master, Cuizhu is born as a third-grade spiritual weapon, but you also have to risk the loss of Cuizhu, once you fail, it will not be a steel sword that will turn into ashes. With his hands spread out casually, Mo Xian said to Yun Yu.

"Hehe, let's still forge a steel sword, a three-grade spiritual weapon...... It's better to keep the bottom of the pressure box. Yun Yu raised his eyebrows and said, if forging a spiritual weapon makes him lose the clear water and green bamboo in his hand, he should rather not practice the forger.

"Well, okay, then you pay attention to the flame in the ding, first put in the main material steel sword, when you feel that the steel sword can be completely integrated into the auxiliary materials in the forging of spiritual fire with spiritual power, put the dark iron in, at this time, you must pay attention to the heat, for the flame of the dark iron to be strengthened, until it is baked, do these first. Mo Xian said patiently to Yun Yu.

Hearing Mo Xian's guidance, Yun Yu quickly concentrated, eliminated distracting thoughts, controlled the flames in the ding with both hands, and when he felt that the flames had burned with his rhythm in his heart, he slowly picked up the steel sword, and then quickly threw it into the ding, at this moment, the flames were quickly suppressed, and it was obvious that the burning was more laborious than just now.

"Control the flames, don't be suppressed by the steel sword, don't be impatient during the forging process, it's a hundred times better to be slow than to fail. The thin aura in Yun Yu's body was difficult to control the suppressed flames flexibly, and Mo Xian suddenly became nervous, and said to Yun Yu urgently.

Qi was concentrating, Yun Yu's hands added strength to this tripod wall again, and a new electric blue aura poured into the tripod, the flame seemed to obtain new energy, burning vigorously, and the blue outer flame tightly wrapped the steel sword, making it fully scorched in the flames.

"Almost, Xuantie into the Ding!" After about ten minutes, the steel sword in the Ding that Mo Xian saw began to move slightly, and any end occasionally jumped in the flames, and then he opened his mouth and said to Yun Yu.

Holding a rectangular piece of dark iron half the size of his palm, he threw it directly into the flames without hesitation.

"Smack!" The metal collided, and the black iron and the steel sword docked in the ding, and the flames were suppressed again, and even more powerful than the previous time, seeing that the flames were about to be extinguished, the faint small flames passed through the gap between the steel sword and the black iron, and survived strongly.

"Separate the dark iron and the steel sword, otherwise the flame will be forcibly extinguished, use the aura to control the dark iron on the outer flame, the dark iron needs to be calcined at a high temperature more than the steel sword, otherwise the steel sword will not be refined if the dark iron is melted. Mo Xian said eagerly.

Yun Yu remained silent, according to Mo Xian's guidance, he slowly held up the Xuantie with his aura, until he was above the outer flame, the flame broke out again at the moment when the Xuantie was suspended, and returned to a raging state, Yunyu's forehead was already full of sweat, pouring down like rain, and the sweat passed in front of him, blurring his vision.

"Teacher, the aura in my body has been almost consumed, I'm afraid it's ......" Yun Yu's expression flashed with a hint of reluctance and regret.

"Fart, how much does it cost, now it's all in one go, it's very good, hold on. At this time, Mo Xian chose to encourage, seeing the poor aura in Yun Yu's body, Mo Xian knew in his heart that it had been almost consumed, but once this stage stopped, the previous efforts would be wasted, and now what was tested was the potential aura in Yun Yu's body and his own perseverance.

Although the aura was close to prostration, Yun Yu still did not save the aura, adjusted the coordination between the aura and the flame to his own controllable state, time passed minute by minute, and he saw that there had been a slight change on the surface of the dark iron, and on the extremely dense surface, some inconspicuous pores had begun to distribute, these are the space for the interaction between the main material and the auxiliary material.

"Hold up the steel sword with aura, make it intersect with the dark iron, and then exert as much force as possible to make the two internally connected and enter each other's body. Mo Xian looked at the situation in front of him nervously, and a few beads of sweat were left on his cheeks.

As the steel sword gradually rose, the dark iron also had a strong reaction, and the rectangular section slowly approached the steel sword body, as if by magic, and slowly the two began to combine.

A solid section of dark iron seems to have been magical, softened, slowly melted, little by little wrapped on the steel sword body, occasionally a few drops of pure black viscous liquid dripped into the flames, but before it fell to the bottom of the ding, it had turned into a cloud of mist and disappeared in the ding, so reciprocating cycle, a piece of dark iron actually slowly disappeared in the bronze ding, and finally the surface of the steel sword body seemed to be coated with a thick layer of charred black iron mold, suspended above the flames.

Slowly, the layer of charred black mold on the sword body gradually thinned, as if it was fused into the sword body, and the volume was also smaller, and finally the silver color of the sword body itself was gradually revealed, and a cloud of white mist flew around the sword body, until the whole body of the sword changed back to its original color, and the traces that had appeared in the dark iron disappeared completely.

"Phew, little one, take a break, that's half the way. Mo Xian sighed and said to Yun Yu.

Yun Yu didn't even have the strength to retract his aura, he directly stopped forging, and lay on the ground all of a sudden, panting, and didn't bother to open his eyelids again, this time the extreme forging had already exhausted him.

"Teacher, it seems that my little aura is really not enough for forging, I feel like I can't even move now. Yun Yu lay lazily on the ground and said with his eyes closed.

"Don't lie down, get up and cultivate the spirit replenishment, there is only one process left to complete, don't you want to be a first-class forging master?" Mo Xian looked at Yun Yu, who was lying down, frowned, and said.

Yun Yu sighed and shook his head slightly, didn't say anything, sat up reluctantly, feeling that even sitting down had consumed a lot of spiritual energy, his hands became a cultivation hand shape, and he began to replenish the spirit, in his heart, the forging master is now the only way for him to get ahead.

"That's enough, the two-star aura has almost recovered, let's start. After a short rest of about two hours, Yun Yu, who was immersed in the greedy state of acquiring aura, was cruelly interrupted by Mo Xian.

"Uh...... This forging is really hard, I was tired just now and I was overdrawn, and I had to do it with intensity before I had a good rest, which was really a cruel practice process. There was a complaint in his heart, but Yun Yu still walked to the bronze tripod as Mo Xian said, took a deep breath, and continued the state just now.

After the flame stopped the injection of spiritual energy, it burned very peacefully, compared to before, the change of the steel sword was also very insignificant, Yun Yu held the green bamboo again, and two small lightning bolts drilled into the mouth of the Ding from the green bamboo, and the flames burned violently and strongly.

"Put in the wolf bone armor and tortoise shell, and the speed must be controlled, so that it can pass through the outer flame to the bottom of the ding as quickly as possible, otherwise the high temperature of the spiritual fire outer flame can turn these materials into ashes at once. Mo Xian said cautiously with a serious attitude.

When Yun Yu heard this, he was also cautious, holding wolf bones and tortoise shells, and around the Dingbi, he didn't dare to put them in for a long time, for fear that he would lose all the dishes because of a moment of carelessness.

"Silly boy, what else to see, it will be in vain to miss the opportunity in the forging machine, throw it in, and use the aura to accelerate to the bottom of the ding. Looking at Yun Yu who was hesitant, Mo Xian quite understood, after all, when he first forged the weapon, he had already failed several times in the fusion stage of the steel sword and the dark iron, and for the current situation, Yun Yu was already extremely talented.

Hearing the pointing, Yun Yu frowned slightly, his hands exerted his strength fiercely, and two small pieces of tortoise shell and wolf bone were like cannonballs, which were shot out by the electric blue aura, until the bottom of the ding, and slowly burned at the low temperature in the center of the flame.

The smoke of various colors in the bronze tripod is swirling, so the good tripod is like this, it is completely possible to control any smoke fired out in the tripod, and will not float out to interfere with the forger's control, at this time the tripod is hazy, and the prototype of the spirit sword and the two auxiliary materials can no longer be seen, and Yunyu is also flustered.

"This is the case with a first-grade spiritual weapon, and because your spiritual energy is too weak and the first forging weapon will be filled with a lot of colored smoke from the firing, it will not be like this if you are proficient, you can use your spiritual power to feel the position of the materials in the ding, and now you will hold up the tortoise shell and wolf bone that are about to melt with your spiritual energy, and completely integrate it into the steel sword. When Mo Xian saw this, he ordered it in time.

According to Mo Xian's words, Yun Yu quickly concentrated, and in the smoke, using the position of the spiritual power explorer's auxiliary materials, he felt that the tortoise shell and wolf bone had basically melted, Yun Yu adjusted his breathing, and slowly held it up, the corners of his mouth slightly raised a confident arc.

Like two sticks of viscous liquid, it was forcibly splashed on the sword body, and suddenly, the surface of the sword body emitted a hot white mist, countless beating water droplets stood on it, Yun Yu's control became more and more proficient, the steel sword circled above the outer flame like a flying machine, and soon the white mist and water droplets disappeared in the ding, and the colored smoke gradually receded, and the sight in the ding returned to transparency again.

"What we have to do now is to control it, the spirit weapon sword has been formed, use the aura to control it to stay in the flames for a while, in a certain period of time, the longer it hovers, the quality of the spirit weapon sword is good. He nodded affirmatively, and Mo Xian breathed a sigh of relief.

The spirit weapon sword hovered happily above the flames, and every time he turned around, one more light would be revealed on the sword body, and the rays of light gathered together, forming a large circle of light wrapped around the spirit sword, his eyes flashed, Yun Yu's heart was very excited, and it also reminded him that when Haiquan forged the Liyu Sword, the spirit weapon that had just been baked made people's eyes shine, and this effect is now from his own hands, and the forging weapon has finally succeeded.

"Okay, out of the tripod, the last step is also very important, remember to be fast, and don't change the trajectory of the spirit sword, let it come out of the tripod in a hovering state!" At the last moment, Mo Xian was finally relieved and made a final advice.

White light shrouded the bronze tripod, and the spirit sword swirled out of the tripod, slowly rising around the tripod mouth, and Yun Yu and Mo Xian showed satisfied smiles on their faces.

Slightly unloaded, one hand controlled the spirit weapon sword with aura, and after hovering over Xiao Ding for several weeks, it finally fell slowly, just being held in Yun Yu's hand, panting, looking at the first spirit weapon he forged, although it was a first product, he was also excited.

Mo Xian nodded slightly, smiling and brushing his white beard, thinking in his heart: "This little guy's talent is amazing, the first forging, the precedent of forging a spirit sword at one time is probably in the spirit realm, this is the first person, such a talent, it is terrifying......"

"Yunyu Forge, the old man congratulates you!"
