There are all kinds of furnaces and raw materials, even the Gushan Heart Fire Gold, which Nie Feng has always regarded as rare, has already prepared a large piece, which is enough for Nie Feng to squander to his heart's content, listening to Duo Lian, the Gushan Heart Fire Gold is not a very rare thing here, and it can be easily purchased from the refining room for only more than twenty credit points.

Of course, Nian Duolian's cheap Nie Feng only heard it, the former was originally relatively rich, especially when he passed through Baishentan, he also made a lot of money, otherwise he would not be able to scrape together the funds to build his own ingenuity shop with less than a year of hard work after coming to Qingshanmen.

The appearance of Gushan Heart Fire Gold made Nie Feng breathe a big sigh of relief from the beginning.

With his sword-casting cultivation, he could have successfully cast a high-grade iron sword of good quality without the fire gold of the ancient mountain, but he had to say that it required a lot of his energy and sword qi cultivation, with his experience in the sword casting shop in Guyun City, he could only cast up to two high-grade iron swords a day on average, and it would take two to three days for cultivation every day of casting, otherwise it would be difficult to maintain his cultivation and energy at his peak, which would indirectly affect the process of sword casting and the quality of the iron sword。

And the existence of Gushan Heart Fire Gold undoubtedly solves this problem.

Gushan Heart Fire Gold is an ore containing rich free sword qi and special materials, adding Gushan Heart Fire Gold in the process of sword casting can not only improve the tenacity of the iron sword, but also directly improve the quality of the iron sword with the help of the rich sword qi contained in it, and the free sword energy in it is easy to mix with other raw materials, unlike the sword caster's own sword qi is rejected by the sword casting raw materials themselves, which not only greatly saves the consumption of the swordsmith's own sword qi, but also makes the entire sword casting process much easier and easier, and the final quality of the iron sword is also good。

Therefore, when most swordsmiths cast iron swords, whenever there is an ancient mountain heart fire gold around them, they almost like to add a little bit to the casting pool, and the same is true for Jin Lao, who cast swords on the periphery of the barbaric mountain range, but at that time, Jin Lao's cultivation was not high, so he regarded the ancient mountain heart fire gold as an indispensable material for melting sword qi.

With a flat push of his right palm, a faint sword qi came out of his body, pouring into the rising flames in the furnace, and under Nie Feng's promotion, the flames suddenly rose a few inches, and the temperature around the furnace was also much higher in an instant, reflecting Nie Feng's face flushed.

"Enter!"

With a low shout, two iron billets and a piece of earth spirit iron were thrown into the furnace, and in less than a quarter of an hour, a fiery red iron pulp floated out of the furnace, and after the iron pulp was completely heated, a piece of hard mountain wood that had already been divided and a small handful of ancient mountain heart fire gold were thrown into the iron pulp, and then Nie Feng lifted a heavy Ziyun iron bar, went deep into the iron pulp and slowly stirred it, and with his continuous stirring, the Ziyun iron bar was swallowed by the iron pulp inch by inch.

At this moment, Nie Feng is like a master of cooking, carefully considering the food in his hand with all his might, as if he will accidentally let go of the ingredients, resulting in the destruction of his hard work, and that result is obviously completely unacceptable to him now, so his slightly nervous eyes did not blink, and his red face even gradually oozed a little sweat. Of course, the delicacies in Nie Feng's hands were just a fiery red iron soup with a temperature of thousands of degrees.

Another quarter of an hour passed, as if he felt that the time was almost up, only to see Nie Feng reach out and grab a huge iron spoon, and sink into the iron pulp, the next moment the iron spoon was full of iron pulp and was dragged out of it, and then a shaking hand, the fiery red iron pulp was like a red xia waterfall rolling down on the high mountain, the brush rolled down, and below was a heat-insulated sand mold, which held the iron pulp steadily, and the fine sparks splashed around, like a little bit of fireworks.

Ding Ding Ding!

Dangdang!

The sword blank taken out of the sand mold, under the rolling of the anvil and the giant hammer, is like a sprout born from the ground, breaking the inherent shackles, and slowly wriggling and growing as far as the eye can see, not only like a lively fish, but also like a baby croaking to the ground, which makes people love it and make people yearn for it.

Suddenly, Nie Feng's giant hammer slammed, one hand picked up the rudimentary form of the sword blank that was still a little dark red, nodded slightly, and then the palm of his hand shook, and a thin cloud of misty white followed the iron tongs, quickly rushing towards the sword blank, and at the same time, Nie Feng's gaze was tightly condensed, and he immediately seemed to be in a fixed position, motionless.

Nian Duolian, who was not far away, was silently admiring Nie Feng's every move from beginning to end, and she didn't realize that she had already been stupid. It was not the first time she had seen the sword-forging process, but at such a young age as Nie Feng, she acted like a real grandmaster, calmly, firmly and chicly, this courage made her heart shake unconsciously, and in a trance she seemed to have come to a sea of golden flowers, where he breathed incomparably fresh air to his heart's content, and his mood was never comfortable, as if the sea of flowers all over the mountains belonged to her alone, and the endless beauty belonged to her alone.

"Hmm!"

A muffled snort interrupted Nian Duolian's thoughts, and when she stared again, she found that Nie Feng's forehead was covered with cold sweat.

"You...... Are you alright?"

Nie Feng shook his head slightly, and then the iron tongs in his hand were loosened, and the sword blank was thrown to the ground with a "dang long" sound.

"Failed ......"
