Mo Han felt that what the old man Dugu said was reasonable, but he always felt that there was something wrong, but after asking the old man Dugu so many times, the old man Dugu said that there was no problem, and Mo Han couldn't doubt it anymore. After all, according to the method on the Dugu old man Yu Jian, there is nothing wrong, at least Mo Han thinks it is not wrong.

"I knew that when I read books before, I should have read some books about alchemy, refining weapons, and formations!" Mo Han sighed in his heart, silently preparing the things needed for refining weapons.

The model was ready-made, and the sword box containing the Taiji Xuanci heavy sword at that time was fine; the adjustment, according to Mo Han's understanding, according to the old man Dugu, Mo Han only needed to add the heavenly and earthly treasures that he felt could increase the weight to cast.

"By the way, the garbage you got from Nangong Glory and Beidou Qingyun will also be melted together, you don't need it anyway. You just need to remember that with a sword in hand, I have it in the world. The old man Dugu glanced at Mo Han and seemed to think of something.

Mo Han was stunned for a moment, and then he thought about it, he didn't need so many things, and they wouldn't want them for Qi Ling and the others, after all, they all had a force behind them to support, only he was relatively thin. Simply, Mo Han also rummaged through the storage bag that Yin Omen gave him, took out all the heavenly and earthly treasures that he thought was okay, and melted them together when he was ready to cast the sword.

Everything was ready, and when Mo Han was about to smelt, he suddenly found a very serious thing, there was no fire, yes, there was no fire. With the hardness of these natural treasures, it is definitely not possible to smelt by making firewood, the temperature is too low, and it is impossible to play directly.

"Old man Dugu, where can I find a suitable fire. They all have earth fire, sky fire, different fire or something in their refining and alchemy, and I don't do anything about it. "Old man Dugu is Mo Han's encyclopedia, just ask if you don't understand.

The old man Dugu was shocked: "Fire, don't you have fire? The peerless flame reincarnation flame is all on you, where else do you go to find fire." ”

"Reincarnation Flame, isn't that just a trace of mastery? How can this be used, if you are careless and destroy all the materials, won't I be empty?" Mo Han frowned and didn't know what to say.

"What you are refining is not a peerless treasure, what you are refining is a heavy sword, a sword that is heavy enough, and you don't need anything else, as long as it is fire, you can completely refine the impurities in the material. To put it bluntly, you don't need the sword to have enough attributes, as long as it's heavy enough and small enough. The old man Dugu gave Mo Han a blank look, and this glance despised Mo Han's IQ as no different from the mentally retarded.

"Well, you have a point. Mo Han suddenly missed the days when Beidou Qingyun was there, at that time he despised Beidou Qingyun, but now he has been ridiculed by Chi Guoguo.

The reincarnation flame emits a faint blue light, as enchanting and beautiful as crystal.

The metallurgical table made by Mo Han is called a metallurgical table, which is actually similar to the stove used at home, except that the stove pot and the table at home are separated, and Mo Han's metallurgical table "pot" is connected to the table. Underneath the crucible was the place where the fire was lit, and Mo Han carefully placed the reincarnation flame in the flame position of the metallurgical platform, so that it could warm up the entire platform.

Samsara Inflammation, whether it is hot or cold, exudes a high temperature that can satisfy Mo Han, but one is extremely hot and the other is extremely cold.

Mo Han, the main material for refining the heavy sword, has already thought about what to use, that is, the Taiji Xuanci heavy sword in his hand, according to the old man Dugu, the Taiji Xuanci heavy sword has not been refined. At that time, when he found Taiji Xuanci Iron, he didn't have time, so for convenience, he used it casually, so if Mo Han wanted to use it, he had to refine it again in order to be handy.

Put the Tai Chi Xuanci heavy sword into the crucible, and the crucible immediately came with a sizzling sound. It's just that this Taiji Xuanci heavy sword may be a heavy treasure as the old man Dugu said, so after putting it in, there is a sound of light coming out, but there is no sign of melting.

On the contrary, the crucible made of black stone turned red under the scorching heat of reincarnation, as if it was about to melt.

"Don't worry, don't worry, this black stone itself is a high-temperature resistant material, and it won't melt no matter how you burn it. Mo Han didn't know where Old Man Dugu's confidence came from, but what Old Man Dugu said seemed to be a fact, "Boy, this reincarnation flame has not fully recovered, and from time to time throw a few yuan stones under the crucible as fuel."

Mo Han took out a bunch of yuan stones from the ring and put them next to him, although there were no top-grade yuan stones, but most of them were still high-grade yuan stones: "Uncle Dugu, what you said is right, what you say is no problem, master, I listen to you." ”

Another day and night passed, and Mo Han was almost asleep sitting in front of the metallurgical platform, and finally saw that the Taiji Xuanci heavy sword in the crucible had a hint of melting.

"Boy, you have to take care of the reincarnation flame and keep it at a constant temperature during the smelting process, otherwise the uneven refining of your materials will eventually affect the quality of the heavy sword you forged. Old man Dugu pointed at Mo Han from time to time.

In Mo Han's gaze, the Taiji Xuanci Heavy Sword melted little by little, turning into a viscous liquid that landed at the bottom of the crucible. The liquid of the Tai Chi Xuanci Heavy Sword is a clear blue, and there are silver spots mixed with it, which is very beautiful.

With melting in the first place, melting in the rest is not a problem. But even so, the melting of the Tai Chi Xuan Magnetic Heavy Sword was extremely slow, often taking several minutes to melt a piece the size of a fingernail.

Mo Han's two eyes stared unblinking, for fear that he would miss a little bit, causing him to fail to forge a sword for the first time.

Half a month has passed in a flash, and the Taiji Xuanci heavy sword has all melted, turning into a puddle of liquid at the bottom of the crucible, bubbling and bubbling.

According to the old man Dugu, as long as there are bubbles, it means that the impurities in it have not been completely removed. Mo Han had to wait until all the impurities inside were removed before he could melt the new material into it.

Looking at the thick layer of black impurities on the edge of the crucible, Mo Han had a whimsical thought: "I said Dugu old man, when you deal with it, won't you just make the Taiji Xuanci heavy sword on the basis of the original ore?"

The old man Dugu blushed: "That's true." ”

"Tyrannical Celestial Thing! Tyrannical Celestial Thing! You said a good piece of ore, why did you only take out a part of it, and didn't take out all of it?" Mo Han suddenly beat his chest, looking distressed.

The process of Mo Han's casting was boring, but he couldn't get distracted yet, and when there were no more bubbles coming out of the blue liquid of the melted Taiji Xuanci heavy sword in the crucible, Mo Han suddenly stood up from the ground and put the materials he had prepared before into the crucible one by one.

The other materials that were prepared, melted down, were not as difficult as the Taiji Xuanci Heavy Sword, and it could even be said to be extremely simple and fast. As soon as it is put into the crucible, it melts immediately, and the impurities are removed during the melting process, and there are no bubbles.

Until this time, Mo Han also knew how valuable the Taiji Xuanci Iron was and how high the temperature of the Reincarnation Flame was. Because even the treasure given to him by Nangong Glory was put into it, it was melted in less than a second.

According to the casting method on the jade slip of the old man Dugu, after all the materials are melted, they are cast.

Mo Han looked at the blue liquid that was melted into one, with a little silver half, and the pride in his heart couldn't help but arise spontaneously, and when he was about to withdraw the reincarnation flame, lift the metallurgical table, and cast the liquid into the sword box, the liquid in the crucible suddenly boiled, as if it exploded.

"It's not good, boy, I forgot one thing, your reincarnation flame has its own yin and yang attributes, it is a mixture of extreme yang and extreme yin, and after these liquids have been calcined by the reincarnation flame for a long time, they naturally also have yin and yang attributes. Since ancient times, yin and yang have been incompatible, and it is a fool's dream to forcibly fuse them into one now. The old man Dugu slapped his thigh suddenly, as if he had just thought of this stubble.

"Old man Dugu, your uncle, tell me what to do now. Mo Han immediately jumped up from the ground, he didn't feel distressed if the heavy sword forging was unsuccessful, he was distressed by the thousands of heavenly and earthly treasures in this liquid.

"Polar fruit, yes, polar fruit. Quickly take out the two pole fruits and put them in it, only in this way can the yin and yang be balanced and not explode!" The old man Dugu stood at the bottom of the Linglong Pagoda, and he was also anxious, not knowing what he thought, the two pole fruits suddenly collapsed into his mind.

"Old fellow, quickly throw out the two pole fruits, or this pot of good dishes will be over." Thinking of the Polar Fruit, the old man Dugu roared towards the place where the demon seed was.

The Purple Gold Dragon King among the demon seeds was awakened from his slumber by the shouting of the old man Dugu, and as soon as he woke up, he passed through Mo Han's body and saw everything outside: "Fuck, old boy, do you fucking know how to refine weapons, are you refining weapons? ”

"Here you go!" At this point, it was useless to say anything, and I could only wait for the liquid in the cauldron to completely calm down before thinking of other ways. The Purple Gold Dragon King roared for a while, and hurriedly threw the unripe Polar Fruit out of the Demon Seed: "Mo Han boy, immediately put the Polar Fruit into the crucible to see if you can balance this yin and yang." ”

The effect of the Polar Fruit was immediate, and although it was not ripe, it was enough for the azure liquid in the crucible at the moment.

Two small streams of liquid, one black and one white, are constantly swimming in the azure liquid, like two small dragons, perfectly combining the yin and yang breath contained in the azure liquid, and finally melting into one.

"Mo Han boy, listen to me, the old man told you that there is no problem with the casting method, but it is the roughest method. You've melted all the materials into one now, and there's no other way to do it for the time being. But when the cooling is done after casting, you can use the hammer you made to keep beating and quenching to further increase its hardness. "The Purple Gold Dragon King can't wait to beat up the old man Dugu.
