A piece of piano stone, thousands of years of passers-by to find. The tooth period occasionally meets, and the landscape perceives the sound. The big wood is empty, and the high platform overlooks the sun and yin. Desolate and nostalgic, the ape and crane help to mourn.

In this poem "Boya Absolute String Diagram", the author pretended to use the allusion of Bo Ya who lost his acquaintance in Hanyang Guqin Tai and threw the piano in anger to show that he was unswerving and expressed his deep feelings for his homeland.

Hanyang, the place where Wuhan city originated. In the second year of the Sui Dynasty (606), according to the meaning of "the south of the mountain and the north of the water are yang", it was named Hanyang County for the first time. The Han River surrounds Hanyang and flows into the Yangtze River from the south of Guishan Mountain.

To the north of Hanyang City, there are two mountains of turtles and snakes. The original name of Snake Mountain was Huanghu Mountain, because of its shape winding like a snake, the descendants named it "Snake Mountain".

Turtle Mountain, according to legend, is Dayu to control the water as for the Dabie Mountain, the middle of which is uplifted, there is a head stretching into the river, just like a big turtle, so it is named.

Turtle Mountain is adjacent to the big river in front of it, and the Han River is in the north, and it is majestic.

The smoke and rain are reckless, and the turtle and snake lock the river.

Dugu Xiaotian was standing on the Moon Tree Pavilion in Turtle Mountain at this time, looking down on the water of the mighty Yangtze River by the railing. It has been six days since he came to Hanyang, and every day he will come to Guishan to observe the mountain situation, and confirm it with the seven sets of exercises of the Zhenwu Seven Interception Formation.

"Tomorrow, my Pingtian Sword will be reforged." Xiaotian happily muttered to himself.

Dugu Xiaotian arrived in Hanyang and stayed at the inn. He found out at the inn that the most famous blacksmith shop in Hanyang was the "Zhang's Craftsman's Shop", so he rushed over with the hilt and fragments of the Pingtian Sword.

After thousands of years of development, the casting of Chinese cold weapons in the Ming Dynasty has reached the point of perfection.

Emperor Yongle was born in the army and was very keen on weapons, and he had a battalion of divine machines, all equipped with the most advanced weapons, which could be called the special forces of that era.

The Shenji Battalion is not only equipped with traditional swords, but also advanced muskets, and the weapons used by the Shenji Battalion are very powerful, and the swords are as sharp as clay.

"Zhang's Craftsman's Shop" is not large, only a dozen zhang long and wide, located in the northwest corner of Hanyang Street, and the blacksmith shop has been inherited for more than 100 years. The shopkeeper was in his forties, burly and tall, and he had three apprentices, who usually did the work of forging.

Dugu Xiaotian saw Zhang Dezhi's second disciple Li Youde, unwrapped the package, and explained the intention.

Li Youde frowned deeply, "Little brother, your sword is just an ordinary sword in the army, the steel quality is poor, and there is carbon deposit. Even if it is in good condition, it is still some distance from the finished sword in my shop. It is only worth three taels of silver in the market. ”

"Some parts of this sword body have been shattered into powder, and even if it is returned to the furnace, it can no longer be restored to its original appearance of three feet six inches and seven pounds and three taels. If the sword fragments are melted, only steel can be added, which must rely on the method of deep tempering to become one and become a usable sword. Such a complex process is too costly! ”

"You really might as well spend five taels of silver to buy the finished sword in my shop." Li Youde persuaded.

Dugu Xiaotian gave Li Youde a deep look, and said softly, "The younger generation does not dare to embarrass the master, this sword is a relic of the father, after the death of the father, he has been dependent on me for his life, and the feelings are deep, and I hope that the master will be perfect." Gold and silver foreign objects, just a small thing. ”

Li Youde saw that Dugu Xiaotian was so persistent, and he was willing to spend more silver taels, so he invited his master Zhang Dezhi and told him what happened.

"I didn't expect that there would be a time when the folding steel technology would be used!" Zhang Dezhi had a loud voice and laughed.

After the Tang and Song dynasties, because of the development of the steel filling process, the 100-steel forging process was time-consuming and laborious, and was rarely used.

"Little brother, I appreciate your filial piety. To reforge this sword, it will take me personally to forge steel, and it will take at least five days to complete. Do you have any specific requirements? ”

"The sword is three feet six inches long, and the sword is heavy..."Dugu Xiaotian groaned slightly, "Now that my martial arts have advanced greatly, the original weight of the Pingtian Sword is indeed not enough to take advantage of." ”

"May I ask Master Liu, can this sword be reforged more than ten times heavier than the original?" Dugu Xiaotian bowed down and asked.

"This is not difficult, the length of the sword remains the same, the thickness and width of the sword body are thickened, and then the hilt is melted, and the hilt itself can be made of more steel." Zhang Dezhi smiled. "Little brother, you can try all kinds of weapons on my weapon rack, the weight is marked on the weapon, find a good weight."

Dugu Xiaotian picked up the hammer and broadsword and other heavy weapons in the blacksmith shop and waved them a few times, thinking in his heart: "Wujicuo's Xuantie rod is extremely powerful, it is inevitable that it will not be encountered again in the future, don't let the Pingtian Sword be destroyed again."

"Eighty-six pounds!" Dugu Xiaotian pondered for a moment and said firmly.

Zhang Dezhi's master and apprentice were shocked when they heard this, "Little brother is sure to build an eighty-six-pound sword?" This sword is more than ten times the weight of an ordinary sword, and it is extremely heavy, which is not convenient for performing light and agile swordsmanship," Liu Qingshui said with a solemn face.

Dugu Xiaotian picked up the hundred-pound silver sledgehammer on the weapon rack and waved it a few times, "Don't worry, master, the younger generation has great strength to make such a heavy sword." ”

Speaking of this, Dugu Xiaotian paused slightly, and said with a sad face, "Please don't modify the overall sword style, and merge the fragments into the middle of the new sword." On the front of the hilt, engrave the word 'Ping', and on the back of the hilt, engrave the word 'Xia'. After that, he wrote the words "Ping" and "Xia" on the table with his fingers.

Looking at Dugu Xiaotian's sentimental expression, Zhang Dezhi had a general understanding in his heart. "Please write these two words on the paper with pen and ink, and I will definitely rub them on the hilt of the sword." Dugu Xiaotian was overjoyed when he heard this, he took the pen and ink, and left these two words according to the size Zhang Dezhi said.

Now that the details of the recasting of the sword have been negotiated, Zhang Dezhi pondered for a long time and said, "Little brother, Liu can reforge this Pingtian Sword according to your requirements." ”

Based on the overall consideration, this sword as a whole weighs about 86 pounds, and the sword body is three feet six inches long, one foot one inch wide, and one inch thick. It turned out that the fragments of the Pingtian Sword, I would melt them on fire, temper the impurities in them, and place them in the center of the sword body.

The tip of the sword is five inches, conical shape, and gradually sharpened and narrowed.

The hilt of the sword was a foot long and half a foot thick. Since the blade of the sword is so wide, it can be used as a small shield, and a bevel is made at the end of the hilt, and a two-inch-high armrest is raised. I rubbed those two words according to the handwriting left by the young man.

The four of us pushed other tasks, and it took 6 days to complete the work with all our might. This time the sword was cast, and I went to the labor fee of my apprentices, and I only charged you six hundred taels of silver. At the moment, half of the deposit for the materials will be collected first, and the balance will be paid after six days. ”

Dugu Xiaotian took out a silver ticket from his arms and placed it on the table. "How can you let the masters work in vain, and ask the masters to laugh at the extra silver. I'll take the sword six days later." With that, he walked out of the blacksmith shop and disappeared into the street in an instant.

Li Youde picked up the silver ticket on the table and said in surprise, "Master, this is a pass for one thousand taels of silver, should we return the excess silver taels to him?" ”

Zhang Dezhi was slightly startled, and then laughed loudly: "After being chivalrous, there is no need to retreat, let's use the best refined steel I have saved!" ”

Dugu Xiaotian and Zhang's master and apprentice would not have thought that this strange customization would actually create the "First Divine Soldier" who would be famous in the Central Plains in the future.
