The next day, Fang Zhong got up very early, tempered his body, and did a whole set of exercises, his face was already covered with sweat, ticking on the bluestone floor.

"Huh, fortunately there is a Spirit Gathering Array, otherwise my body would not have improved so quickly. Fang Chong's arms were raised high and clenched into fists, and he felt the powerful power rushing through his body, which made him overjoyed.

With the help of the Spirit Gathering Array, his body's ascension speed not only did not slow down, but soared rapidly.

As time passed, Fang Zhong found that his own body and the spirit gathering array had become more closely compatible, and the rolling heaven and earth spiritual qi flowed through the muscles, bones, and bloodlines, becoming more and more docile, and it was easier to absorb than before, so it was difficult for his physical fitness not to improve.

The physical training did not fall, and at the same time, Fang Zhong was constantly trying to stimulate the aura of the Spirit Gathering Array, which evolved into something similar to internal strength.

However, after a whole month or two, there was no progress in the slightest, it was too difficult to control the aura of the Spirit Gathering Array, the reason why it was able to succeed last time was completely accidental, and it was not a simple matter to find the inevitable in the accident, and to control this inevitability.

However, Fang Zhong was not discouraged, he believed that if he persevered, he would always succeed. And he has a lot of things to do now, the most important of which is to study the "Twelve Chapters of Forging".

For two months, Fang Zhong continued to study the "Twelve Chapters of Forging", and confirmed and practiced the skills in them one by one......

The final result was that all the black iron in the blacksmith was refined into fine iron by him.

Of course, some of them were purified with the stamens of the Blue Star Grass, and with the addition of his hand, the refined iron only reached the lower grade of refined iron.

When Fang Zhong had mastered the heat for half a month, as well as the dosage of Blue Star Grass, the refined iron had reached the middle grade, and occasionally there would be some high-grade refined iron, but the purification method of this drug with Blue Star Grass has always had limitations, and it was good to be able to reach the middle grade, and it was almost impossible to refine all the top grades.

Therefore, Fang Chong has now abandoned the drug purification method and started to study the spirit rune purification method!

The so-called spirit rune purification method is actually to use flames to purify metals, but instead of ordinary flames, it is a spiritual fire that has been transformed into a rune seal.

The spiritual fire is purer and the temperature is higher than that of ordinary flames, so it can effectively remove the impurities in the metal, concentrate and refine the metal, so that the black iron becomes cold and radiant fine iron, and can ensure that the refined fine iron is all of the highest quality.

A month later, Fang Zhong had initially mastered the Spirit Rune Purification Method, and he began to prepare to practice.

"Well, there are a few things that need to be prepared before practice, as well as...... A helper. Fang Zhong snickered in his heart and arrested Fang Zongqing.

Who made him have no internal strength?

Activating the talisman seal requires the support of internal strength, and Fang Zongqing is the best candidate, the inner diameter is thick, and it is a fire attribute, it is really good to use it to forge metal.

In the blacksmith shop, Fang Zongqing watched Fang Chong carve dense lines on the furnace, and he was very puzzled when he felt crooked, and asked, "Chong'er, what are you doing here?"

Fang Zhong smiled and said, "Dad, my name is Fu Seal, it's hard to explain, you just need to know that with this thing, we can refine high-grade fine iron." ”

"Oh, I see. Fang Zongqing suddenly realized, no longer asked, let him strike the iron is okay, but it is really difficult to understand these complex talismans, anyway, his son understands it, he is happy and relaxed, sitting on the side with his arms crossed, waiting patiently.

After half a ring......

"It's done!" Fang Chong's face was overjoyed, and he carved a strange pattern on the furnace at the end, and said: "Dad, it's time for you to make a move, quickly use your 'Flame Technique', this fire attribute internal strength, used to refine metal, forging weapons is really good, and it is perfect to cooperate with my talisman seal." ”

"Uh, the 'Flame Technique' is a martial arts secret book, and it was actually turned out by you to be a trick for striking iron, hehe...."Fang Zongqing couldn't help but smile bitterly, but still put his hand on the furnace.

Laugh at!

With a soft sound, Fang Zongqing's arm suddenly turned red, and a trace of fiery red light seeped out, which was the true manifestation of internal strength, and all of them spontaneously rushed to the furnace, swimming along the talisman seal engraved on it by Fang Chong, outlining a peculiar pattern.

With the injection of the internal strength of the 'Flame Technique', the talisman seal on the furnace suddenly lit up, bright as fire.

In Fang Zongqing's surprised gaze, the internal energy that had been transformed by the talisman seal turned into a strange flame, floating into the furnace like red clouds.

"Hey, the black iron melted, it was so fast!" Fang Zongqing was taken aback, his eyes staring straight at the black iron inside the furnace.

In the furnace, the dozens of catties of black iron melted easily when he touched the cloud-shaped flame, and the speed was more than ten times faster than his usual forging with ordinary flames.

Fang Chong stood next to Fang Zongqing and laughed happily.

Fu seal purification method, this is a more advanced thing than the drug purification method, no internal strength can not be used at all, from this point can be seen, the effect of refining metals must be very extraordinary.

In just a short moment, dozens of catties of black iron all turned into molten iron, boiling and tumbling in the furnace, emitting wisps of black smoke.

The black smoke is all impurities inside, the black smoke is evaporated, and the black iron in it has become more pure, and the volume has become much smaller, dozens of catties of black iron, now it looks like only ten catties, just the first smelting is less than half.

Half an hour later, dozens of catties of black iron had all been smelted into refined iron, and the volume had shrunk by more than ten times.

Sonorous!

Fang Zongqing took out the refined iron in the furnace, waited until it cooled down before putting it in his hand and weighed it, and exclaimed: "Good guy, dozens of catties of black iron, there are only less than two catties when smelted, the grade of these two catties of refined iron will definitely not be too bad, it should be regarded as a top grade." ”

Fang Zhong also came closer to take a look, and smiled with satisfaction, judging from the color of this piece of fine iron, he knew that it was definitely a high-grade fine iron.

The next thing is forging, and the smelted iron is very irregular, and there is no way to sell it directly, only after simple forging can it be sold.

Of course, if you directly cast fine iron into weapons and so on and sell them at a higher price, but casting weapons can not be completely made of fine iron, you also need to add some other materials, these things are not heavy, so you must sell part of the iron essence before you can buy those materials to cast weapons.

Forging is actually very simple, it is to use a hammer to continuously beat it to achieve a regular shape.

This process was all completed by Fang Chong, he found that in the process of forging, the Spirit Gathering Array in his body would speed up, allowing more heaven and earth spiritual qi to gather into his body, which was equivalent to accelerating the refining of his physique, how could he let go of this kind of opportunity?

Bang bang!

There was a dull sound in the blacksmith's shop, and a huge hammer descended into the air, shaking the chopping board.

......

Three months later, Fang Zhong was fourteen and a half years old.

Fang Zhong and Fang Zongqing got up early in the morning, and after a workout in the yard, the two had breakfast and hurried out of Ningcang County.

In the past three months, Fang Zhong has forged all the gold and black iron in the blacksmith into fine iron, with a total of nearly fifty catties, most of which are low-grade and medium-grade refined iron, and a small part of the high-grade ones, and all of them have been left in the blacksmith by Fang Chong.

This time, they were going to take the forged fine iron to the city of Zhaonan County and sell it, exchange it for silver, and then buy what they needed.

The Xuan-colored samurai uniform, a long knife made of low-grade fine iron mixed with black iron, Fang Zhong and Fang Zongqing were equipped with a set, and they quickly walked along the official road, kicking up a puff of dust, and disappeared in a blink of an eye.

Ningcang County is far away from Zhaonan County, thousands of miles, it is impossible to rush back in a day or two, and there are robbers and unscrupulous horse thieves along the way, the danger is much higher than in Ningcang County, so they can't be cautious.

Therefore, a long knife is a must, and although it is not necessary to encounter robbers or horse thieves, it is always good to be prepared.

Fang Zongqing has the cultivation of the peak of a second-rate martial artist, ordinary robbers are naturally not afraid, Fang Chong also has the cultivation of a third-rate martial artist, although it is slightly insufficient, but it will not fall behind when it comes to real fighting, the only thing that makes Fang Zongqing frown is the heavy armor of more than three hundred catties on Fang Chong's body.

This thing is a burden when it comes to fighting.

However, Fang Zhong didn't care at all, with his current physical fitness, more than three hundred catties was actually a bit light, and the exercise effect that could be played was somewhat insufficient, and there was not much obstacle to his speed and agility.

But with heavy armor on his body, his defense ability has at least tripled, so why not?
