Coming to Datang, Bu Yunfei's only purpose of survival seems to be to explore the secret of this spring steel!

To this day, Bu Yunfei not only found nothing, but was led into a huge whirlpool one after another by this spring steel, sinking deeper and deeper, unable to extricate himself! So much so that he came to the end of his life - tomorrow's sacrifice of the sword, nine deaths!

It seems that this spring steel is a hoodoo!

In the fire, it seems to reflect the wrinkled faces of the old craftsmen in the mountains of Yunnan, and the flames that rise with them become more and more strange and meaningful!

Cao Senjun handed over a drawing with both hands: "Mr. Bu, this is the sword pattern designed by Master Ma himself, please Mr. Bu build it according to the pattern." Pen %Fun %Pavilion www.biquge.info"

Bu Yunfei sighed lightly, handed the spring steel to Fang Ruoxu, and took the pattern.

The pattern is a long sword, the sword is five feet long, the handle is seven inches long, the sword body is three inches wide, the sword head is wide and protruding, the sword body is narrow, the blades are on both sides, and the sword body is covered with water lines, which is quite kingly!

Song Wuyang stepped forward and took a look: "Big brother, this is the Panlong Sword!" It's the sword of kings! It's just that Master Ma has made some improvements, widened the sword body, and painted a flowing water pattern, which looks more domineering! It's just that this flowing water pattern is not easy to play! ”

"Song Wuyang, I want you to talk more, the eldest brother is well-informed, and he hasn't seen anything!" Fang Ruoxu drank.

Bu Yunfei shook his head: "This dragon sword, I really haven't seen it!" ”

"Stop talking nonsense!" Ba Yegu became impatient: "Big brother, what do you say?" ”

Bu Yunfei looked at the iron furnace that was rising in flames, and the illusory face of the old craftsman loomed in the furnace fire.

"Running water!" Bu Yunfei gritted his teeth and said.

"Great!" The crowd responded in unison.

On Ma Sui's sword pattern, the sword body is covered with water patterns, which is exquisite, which is a typical patterned steel! The water pattern on the patterned steel seems to be decorative, but in fact, it is not, it is a natural phenomenon of folding and forging. The so-called folding forging is the overlapping forging of hard and soft steel to remove impurities and make the carbon distribution more uniform, so as to create a sword with excellent toughness and hardness. During repeated forging, various textures appear on the sword.

Forging techniques include group beating, running water, rotary welding, horse teeth, etc., different forging methods, the texture of the sword body is different, there are flowing water patterns, group patterns, snow flake patterns, thumb fingerprints and so on.

In the 21st century, the most popular are flowing water and rotary welding, while in the Tang Dynasty in the 8th century AD, group beating was the most popular, but the process was relatively rough.

From the perspective of the 21st century, the flowing water method is more advanced than the group fight, and the quality of the sword cast is very different! A sword made by the flowing water method can easily cut off the sword of the group!

However, although the flowing water forging method can be achieved in the Tang Dynasty, the technology is not perfect, and it is often self-defeating, and the products created are not as good as group fighting. In the eyes of the Tang people, flowing water is not as good as group fighting. Therefore, in Chang'an City, Bu Yunfei builds ironware, which is a group fighting method.

And today, Bu Yunfei is determined to use the flowing water method to forge a sword!

He can't insult this spring steel!

This spring steel brought him calamity, and it also brought him once-in-a-lifetime luck - because of it, Bu Yunfei met Qin Xiaoxiao, and because of it, Bu Yunfei met Yan Gaoqing!

What's more, there is a flowing water pattern drawn on the pattern! Only the flowing water forging method can create such a texture!

Ma Sui doesn't know how to forge a sword, he just thinks that this texture is more domineering! He didn't know that it was the result of flowing water forging!

Bu Yunfei wants to use this spring steel to cast the king of swords!

I'm going to die tomorrow! To be able to forge such a sword, it is not in vain to come to Datang!

The snow was falling, and the four brothers took off their shirts, went shirtless, and worked hard in front of the fire!

……

The sun climbed out of the clouds, and the sparse sunlight sprinkled down with a chill without the slightest warmth.

A night of wind and snow, an endless North China wilderness, thousands of miles of ice!

A few crows landed in the snow and searched in vain in the snow-covered snow, occasionally letting out a mournful cry of disappointment or two.

In the depths of the snowfield, there was a roar like thunder, and the snow layer covering the earth, with that roar, trembled slightly, and slight cracks appeared, and the snow on the trees fell one after another.

The crow soared into the air, hovering among the clouds in panic, looking for the source of the roar.

On the eastern horizon, a black wave appeared, sweeping towards the silvery white earth.

The Kuroshio ruthlessly devoured the silvery snowfield, and everywhere it passed, the snowfield was shattered and in shambles!

Above the Kuroshio, layers of dense swords, guns and flags emitted a dazzling cold light in the cold sun!

This is a great army, sweeping from the east with a thunderous momentum!

They are one of the most elite armies in the Tang Dynasty, known as the Fan Yang Army, known as the victorious army!

In fact, in terms of combat effectiveness alone, the most powerful unit in Datang should be the Anxi Army!

However, judging from the record record, the Anxi army is far inferior to the Fan Yang army!

The mighty Ansi Army once swept through the Western Regions and reached Lake Baikal; However, in the face of the equally powerful Tibetan and Persian armies, in the harsh environment of the ice and snow in the north and south of the Tianshan Mountains, the Shuofang army also had many defeats, and even had a bad record of the annihilation of the whole army!

And Fan Yangjun is facing the semi-civilized Khitan, Tongluo, Xi people, and the declining Turkic people, so they are almost invincible!

It is precisely because of this superficial phenomenon that Fan Yangjun is mistaken for a model of the Tang army!

And their commander, An Lushan, is regarded as the god of war by the world!

As the god of war, An Lushan made the mood of the imperial court extremely conflicted!

On the one hand, the imperial court regarded him as the Optimus Prime of the Northeast Frontier, and the central leaders, including the emperor, took it for granted that without An Lushan, there would be no peace in the Northeast Frontier! Only a very small number of sober-minded people know that without An Lushan, the Northeast Frontier should be more peaceful!

On the other hand, An Lushan has a strong armed force, which makes the imperial court quite a headache! From Hebei to Chang'an, in the vast territory of the Tang Dynasty for thousands of miles, there is no army that can compete with the Fan Yang army!

Heavy on the outside and light on the inside - this Datang fibroid is swelling day by day!

However, what makes people sigh is that this situation was single-handedly promoted by the current emperor!

Just three months ago, the Tang Emperor also issued a holy decree, ordering thirty-two Hu officers recommended by An Lushan to replace the Han officers of the Fan Yang Army!

The emperor's favor for An Lushan has reached the point of losing his principles!

Even Yang Guozhong, the chief prime minister of the Tang Dynasty, An Lushan's sworn enemy, is helpless about this!

From Fanyang to Chang'an, it is almost undefended! Since there is an Lushan as a barrier, why do you need to fortify!

However, the emperor never expected that overnight, this barrier would turn into a sharp sword and be quietly inserted into the heart of Datang!

The 180,000 army went south, and in Hebei, not only did they not encounter the slightest resistance, but they did not even reach Chang'an!

An Lushan sat on a huge iron platform.

The iron is more than one zhang high, two battles long, and five zhang wide! It is covered with an apricot-yellow banner and surrounded by a silver fence. The front is led by sixteen tall horses. The shape of the iron is beyond the specifications of the prince, and it is only one step away from the emperor!

In fact, An Lushan took the iron opinion, but it was not a transgression.

This is really because he is too fat!

With a weight of more than two hundred catties, coupled with its special gold chain mail, ordinary war horses can't bear it! Even the wooden car, holding An Lushan out of less than ten miles, will fall apart!

However, such a figure also brings him a lot of benefits!

One of the biggest advantages is that the current emperor and concubine, because of this figure, see him as a stupid boy with a wide heart and a fat body! Or, a rigoletto!

"An Lushan, what do you have in your big belly?" In the Daming Palace, Yang Guifei looked at An Lushan's belly and laughed, and Li Longji stroked his beard and waited for An Lushan's answer with interest.

"Only pretending to be a fierce loyalty to His Majesty!" An Lushan's face was childlike naughtiness.

An Lushan leaned on the iron seat, stroking his high bulging belly, thinking about his wit in facing the emperor in Daming Palace, and a mocking smile appeared on the corner of his mouth!

He was sure that the emperor and the concubine were interested in his big belly, just because, they concluded, there was only a good pair of good ones in that huge belly!

Now, he wants to let the emperor know that there is no water in his stomach, let alone some brave loyalty!

What he has in his belly is the world!

Tolerance is great! If you want to be able to fit the world, of course, you have to have a big belly!

Beside him, a jet-black war horse neighed, attracting the neighing and singing of countless war horses on the field, and the neighing sound converged into earth-shattering thunder, exploding on the field!

It was a thousand black war horses beside the iron that neighed!

That's a thousand horses dragging down the river!

The Thousand Falling Rivers beside the Iron Guards, their complexions varied, yellow, white, brown, and black! Some are blonde and blue-eyed, some are black-haired and black-eyed, and some are purple-haired and green-eyed. They came from different ethnic groups, Han Chinese, Khitan, Tongluo, Xi, Goryeo, Turkic, and even Persian and Dashi from thousands of miles away......

But there are three things in common: first, more than eight feet tall, with a tiger's back and a bear's waist! Second, each person has a long lance, a long knife at the waist, and a bow on his back! Third, black-clothed and black-armored dark horses!

These three points show that every person who drags down the river is a good hand at riding, shooting, and foot combat! They can wield a long lance to charge and break the formation, they can also hold a long knife in hand-to-hand combat, and they can also kill the enemy with one arrow in a hundred steps!

Although the overall combat effectiveness of the Fan Yang Army is not comparable to that of the Anxi Army, this thousand rivers are worthy of the name of the world's first!

A thousand dragged down the river, which can withstand 20,000 Anxi troops!

Therefore, An Lushan is not afraid of Geshuhan's Anxi army!

Tieyu stopped, a thousand dragged down the river, and at the same time stopped advancing, and the war horse snorted and spewed out bursts of white mist.

The river flashed out of a passage, and three war horses galloped and stopped in front of Tieyu.
