And speaking of the encounter between Qin Zhan and Feng Mofeng, this is going to talk about what Feng Mofeng is guarding now.

It is said that after Qin Zhan entered the Dugu Sword Shrine, he naturally found the three swords left behind by Dugu's defeat, among which the wooden sword has nothing to say except for symbolism.

And the green steel sword is made of what material it is made of, it is sharp and fierce, extremely sharp, it can be said to be a rare divine sword in this world, Qin Zhan liked it very much at first sight, so it was naturally directly used by him.

As for the heavy sword, because it was made of dark iron, it was extremely heavy, and Qin Zhan felt that it was too inconsistent with his elegant character, thinking that in the original book, this sword would be smelted into two divine weapons in the future, the Heavenly Sword and the Dragon Slayer Knife, so an idea came into mind in his heart.

Since there is already a Sword Casting City, how can there be no famous swords in the Sword Casting City!

So Qin Zhan decided to re-smelt this dark iron heavy sword and cast it into another divine weapon.

But Qin Zhan is not a swordsmith, he doesn't have the ability to smelt the dark iron, and he has to refine it into a divine weapon.

However, this is not a big problem, since Guo Jing and Huang Rong could do it back then, there is no reason why he Qin Zhan can't, which is his pride as a traverser.

In this era, the casting method of iron has been very perfect, and it is not uncommon for people to make a living from iron, although Qin Zhan can't go to investigate every family, but there is a good saying, the fragrance of wine is not afraid of deep alleys, and people who play iron well are still easy to become famous, after all, this world is a martial arts world.

So by chance, Blacksmith Feng entered Qin Zhan's sight.

Due to the reason of reading the original book, Qin Zhan had an inexplicable sense of familiarity when he saw Blacksmith Feng at first sight, and then as he deepened his understanding, it was naturally not difficult for Qin Zhan to find out that he was Feng Mofeng, Huang Yaoshi's apprentice.

Now that he knew that he was Feng Mofeng, Qin Zhan was extremely interested in him, so he immediately revealed his thoughts without missing anything.

Feng Mofeng is iron-clad, if it weren't for his disability and regrets, he would have already devoted himself to the battlefield to defend his family and country.

At this time, the two immediately coincided, the more they talked, the more speculative they became, and in the end they were already brothers, and Feng Mofeng finally expressed his willingness to join Qin Zhan's plan.

didn't expect that such a big harvest could be achieved by going out by chance, Qin Zhan was immediately ecstatic.

What made Qin Zhan even happier was that Feng Mofeng's forging technique turned out to be the legacy of the swordsmith of the previous dynasty, and legend has it that this swordsmith was also related to Ou Yezi in the pre-Qin period.

Who is Ou Yezi, Qin Zhan knows, that is the founder of the sword casting master in the history of the Central Plains, even if the old inheritance has been dilapidated, it is also very remarkable.

And as soon as everything was done, Qin Zhan naturally asked Feng Mofeng to start thinking of a way to smelt the Xuantie heavy sword.

Since it is dark iron, it is naturally the essence of iron, according to Qin Zhan's thoughts, this is already about to reach the level of special steel in later generations, and the melting point is naturally surprisingly high.

Feng Mofeng tried all kinds of methods, but the conditions of this era were limited after all, and in the end, all of them failed to meet the requirements.

Qin Zhan was also helpless in the face of this situation, after all, he was not a sword forger, and he didn't know what else to do.

Coincidentally, at this time, a piece of news that Feng Mofeng said caught his attention.

"Brother Feng, you mean, this sword may have been forged using earth fire in the first place!" Qin Zhan asked with a look of surprise.

Feng Mofeng took the Xuantie heavy sword, pointed to some pale yellow patterns on it and said: "Brother Qin, please see, the reason why this Xuantie heavy sword has such pale yellow patterns is mainly because it is contaminated with sulfur, and these patterns go deep into the inside of the Xuantie instead of the surface, indicating that this is not later contaminated, but caused by sulfur being integrated into it when the iron is cast." ”

"What Brother Feng means is that after this dark iron is turned into molten iron, there is sulfur mixed into it, and when the iron is actually struck, few people will add sulfur to it!" Qin Zhan seemed to vaguely think of the alloy steel mentioned in the chemistry of later generations, and there seemed to be nothing to add sulfur or the like.

"Brother Qin really knows it at all, so the only thing to say is that this swordsmith was forced to mix dark iron and sulfur together, so I guess that this dark iron sword was forged with earth fire nine times out of ten. Feng Mofeng nodded with a smile and said.

Qin Zhan nodded with a smile and said, "Brother Feng really deserves to be an expert in forging, and you can see so much information at a glance. ”

Feng Mofeng shook his head in distress and said, "What's so powerful, the key is that even if we know the way now, we don't know where there is a fire!"

This time Qin Zhan was stumped, he knew where there was earth fire, as long as there were volcanoes in this world, it was not everywhere.

But the key thing is that those areas don't seem to be in the Central Plains, and even if there are such places, they must be full of poisonous gas, where to find just enough to use earth fire.

In this way, Qin Zhan was puzzled, how did Dugu smelt such a large piece of iron lump in the first place, and how did Huang Rong and Guo Jing smelt the Xuantie Sword.

Could it be that this earth fire is near Xiangyang City? Qin Zhan suddenly had such an idea.

After all, Xiangyang City was already in danger, and it was impossible for Huang Rong and Guo Jing to run far just to refine two weapons, and the only explanation was that this fire was not far from Xiangyang City.

The more Qin Zhan thought about it, the more sure he was that this earth fire was near Xiangyang City.

Now that the scope has been determined, it is naturally easier to find such a place.

So during that period of time, there was a rumor near Xiangyang City, saying that someone saw the immortals flying in the sky near Xiangyang, and that the Mongols were tyrannical and provoked the immortals to descend to earth, which greatly boosted the morale of the people in Xiangyang City.

In fact, where is the immortal, it's just that Qin Zhan was surveying the earth's leylines to find the earth's fire at that time.

Sure enough, the hard work paid off, Qin Zhan rode the eagle and finally turned around Xiangyang City for dozens of miles, and finally found some clues.

It's just that what makes people laugh and cry is that after Qin Zhan and Feng Mofeng's reasoning, the most likely place for this earth fire to exist is actually in the valley of Dugu Sword Tomb.

But in this way, it makes sense.

After all, the Dugu Sword Shrine is really special in the Condor World, first of all, there are two monsters here, the Eagle Eagle and the Giant Snake, and there are also a large number of Pusqu Snakes that can improve their skills, it is a bit like the Lingyun Cave in the Fengyun World, but the scale is smaller.

Sure enough, after the two of them investigated the Dugu Sword Shrine, they really found an Earth Fire Casting Sword Room suspected to have been handed down from before the Song Dynasty in a stone wall in the Sword Shrine.

Qin Zhan thought to himself that maybe Yang Guo might have accidentally discovered this place in the original book, so Guo Jing and Huang Rong thought of a way to smelt the Xuantie Sword, but these things were just trivial and not recorded.

With the earth and fire ready, it is naturally imperative to forge a sword, and after Feng Mofeng's measurement, this Xuantie sword can probably cast three divine swords if it is smelted.

And these three swords had already been given names by Qin Zhan before they were born.
