Mo Longfeng, the hall master of the Beifeng Hall, continued Liu Bufan's words: "The so-called composite melting and casting method is to purify the low-grade materials in batches, and then merge the purified materials together for casting. This method is more cumbersome than nine casts, but it is more efficient. ”

Everyone nodded, Ye Changsheng set the time limit for casting the sword at fifteen days, and naturally the emphasis was on efficiency.

Master Ouyun's previous accusation that Ye Changsheng was not prepared was obviously not the truth, on the contrary, Ye Changsheng's work was well prepared.

The melting and casting of low-grade materials is nothing to look at, everyone can take the overall situation into account, and there is no need to go down to join in the fun.

The real highlight is actually in the last few meltings, which is the focus of everyone's attention.

Moreover, in the low-level casting stage, there are many kinds of materials needed, and the manpower required is also very large, so the hall on the first floor is full of people coming and going, and they are now in the past, just afraid that it will cause chaos.

Master Ou Yun's face was a little gloomy, although he had only just started forging the sword, but the quality shown by the people in the Sword Hall was not even comparable to the Royal Military Creation Bureau.

No wonder Ye Changsheng would seem so confident.

With such a team, not to mention the composite casting method, even the more difficult melting casting method will not go wrong.

Suddenly, Ou Yun's nose wrinkled, and he said in surprise: "Charcoal?"

Charcoal fire?!

Only then did everyone smell the smell of scorch in the air, and they couldn't help but be moved.

Charcoal and charcoal have been used as fuels since the dawn of the sword-forging industry, and they continue to flourish even today.

However, since the Terrans have mastered the attribute spiritual power and magic circle, the more advanced casting uses the spiritual fire generated by the fire attribute magic circle, and the higher level is the natural spiritual fire.

There is no doubt that the spiritual fire provided by the circle is more stable, purer, and easier for the swordsmith to control.

The higher the level of weapon casting, the more you need to accurately grasp the heat.

However, Ye Changsheng actually used charcoal fire in addition to the spiritual fire of the magic circle, which could not but be shocking.

Charcoal fire is the most unstable source of fire, flame and temperature, which will be affected by the outside world anytime and anywhere, thus affecting the melting and casting of materials.

More critically, when the charcoal fire burns, it will release impurities and metal particles, which will adhere to the molten iron to a greater or lesser extent.

Therefore, the texture of the molten iron cast by charcoal fire will also change rapidly, and it is changing all the time.

And this is tantamount to increasing the difficulty of the swordsmith's control.

If it is just an ordinary weapon, this slight difference is naturally nothing, and it is completely negligible.

However, casting a high-grade longsword, even the slightest changes and differences, will affect the material, and then the sword body.

Even because of these inconspicuous differences, it will eventually lead to the failure of sword casting.

How confident is this Ye Changsheng that he dares to use charcoal fire as auxiliary fuel?

Isn't he afraid that because of a slight deviation in a certain link, it will lead to a failure?

Of course, Ye Changsheng did this because he also took a fancy to the benefits of charcoal fuel.

The birth of any great longsword exists in various variables.

The use of charcoal fires increases variables.

Only by adding charcoal fire can the material and the sword body be given a different personality, and those swordsmiths who are obsessed with the ancient method of sword casting call the different personalities of the sword body life.

Regarding Ye Changsheng and Wenjiantang's "extreme", Fang Daqi, the president of the Nine Winds Branch, has the most right to speak, and he will give everyone what Ye Changsheng once told him.

The crowd let out exclamations again, and the old-school masters looked relieved.

With their realm and cultivation, they are less and less dependent on external objects, and they also pay more attention to their own cultivation.

Charcoal and stone charcoal are originally derived from nature, and being able to control and use them is originally the embodiment of the realm.

Ye Changsheng insisted on using the ancient method, which showed that he was sober.

This shows that Ye Changsheng has never lowered his requirements for himself, and he will not compromise for the sake of fame and fortune.

There are thousands of avenues, and different paths lead to the same end.

The way of forging a sword is also the way, and if you truly reach the realm of the unity of heaven and man, and the co-casting of heaven and man, why do you need to rely on external objects?

Although various materials continued to be devoured by the nine furnaces, the number of people in the hall on the first floor began to decrease.

At this time, everyone saw clearly that in front of the nine furnaces, in addition to the refiners who controlled the fire, there were also two swordsmiths who were responsible for controlling them.

In addition, behind the two swordsmiths, they were followed by four young apprentices, who were in charge of recording.

Ma Liming, the general manager who was responsible for coordinating the materials, with nine assistants, stayed in the center of the nine big tripods.

And the Great Elder Lu Wanfang, with a few elders, as well as the charcoal king Jiang Xuenong, constantly wandered between the nine furnaces and listened to the reports of various swordsmiths.

These situations were finally concentrated in Ye Changsheng and summarized, and Ye Changsheng controlled the overall situation.

It's easy to say, but in reality, in the tense rhythm of more than 100 people, it's not so easy to do.

Up to now, the swordsmiths of the Sword Hall have done a good job, so much so that from time to time there were people in the crowd on the second floor who were observing.

The presidents and vice presidents of the Refiner Branch, their performance at this time was just like when Fang Daqi first saw the sword casting in the Sword Hall, and they couldn't help but be amazed and ashamed.

Before these elders came, they were all arrogant, and they didn't really take Ye Changsheng and Wen Jiantang in their eyes.

However, at this moment, after seeing it with their own eyes, they knew that the casting scene of their own branch was simply a disaster compared to that of Wenjiantang!

With such a well-trained swordsmith and apprentice, such a tacit cooperation, I really don't know how it was formed?

Moreover, this tacit understanding is not a little stiff, but it is very smooth, which makes people feel comfortable to watch.

It's as if there is a natural aura flowing in the hall, enveloping everyone in it, so that everyone can act naturally and according to the rhythm of the rhyme.

Everyone couldn't help but look at Ye Changsheng, there was no doubt that the source of this aura was this genius swordsmith who was not yet sixteen years old.

They were amazed, but the next scene was even more shocking.

Ye Changsheng, who had been standing solemnly, finally moved.

Every time he walked in front of a furnace, after only three breaths, the swordsmith in charge shouted, "Shut the furnace!"

"Close!"

"Close!"

"Close!"

......

The nine furnace tripods, almost according to Ye Changsheng's pace, guided the molten iron out.

Of course, this was not because of Ye Changsheng's arrival that the swordsmith ordered the furnace to be closed.

It's because Ye Changsheng took the time of closing the nine furnaces just right!

Oh my God, how much control does this take, how much precise calculations does this take, how terrifying execution does it take, to do all this?

This wave of operations by Ye Changsheng and Wenjian Hall is outrageous and suffocating!
