"Saber Dragon Spring!"

Chen Song said enviously.

Longquan?

Liu couldn't help but shrink his pupils.

Yang Hao didn't expect that Li Bai's saber was actually one of the top ten famous swords in China, the Longquan sword representing the sword of integrity and nobility!

This Longquan Sword, also known as Longyuan Sword, began in the Spring and Autumn Period and the Warring States Period, more than 2,600 years ago.

Legend has it that it was forged by the joint efforts of Ou Yezi and Ganjiang, two great swordsmen.

Legend has it that Ou Yezi and Gan Wei forged this sword, chiseled Kaici Mountain, released the stream water in the mountain, and led it to the seven pools next to the sword-casting furnace to form the Big Dipper Seven Star Ring, which is the name of the Seven Stars.

After the sword is formed, look down at the sword body, as if climbing a high mountain and looking down at the abyss, ethereal and profound, as if there is a giant dragon lying down, it is the name of Longyuan, so the name of this sword is called Seven Star Longyuan, referred to as Longyuan Sword.

In the Tang Dynasty, because of the avoidance of the ancestor Li Yuan, the word Yuan was changed to the word Quan, which became the Seven Star Dragon Spring, referred to as the Longquan Sword.

"That's not right...... There's something wrong here!"

Liu Yiyan shook his head and said: "This sword was Li Yuan's sword, Li Yuan was buried in Xianling with Li Yuan after his death, and it is also rumored that Li Yuan once passed this sword to Li Shimin, Taizong of the Tang Dynasty, and was buried in Zhaoling with Li Shimin...... How could this appear in Li Bai's hands? Could it be that there is a record of this in the historical materials later?"

Chen Song glanced at Liu in surprise.

I didn't expect him to have research on this matter.

"yes, I've heard about it, too!"

Yang Hao also felt that what Chen Song said was very different from what he had heard before.

When I was looking for someone to identify the black sword worn by the black-robed man before, I had heard many people talk about the top ten famous swords in Huaxia, and their statements about the Longquan Sword were also the same.

There is no clear record in the historical materials, however, in Li Bai's poems, the word Longquan often appears, for example, in "Sending General Yulin Tao", there is a sentence of "thousands of miles of Hengge explore the tiger's den, and draw the sword out of Longquan in three cups", and "Farewell Zhang Wu at Night" has the sentence "Longquan unravels the brocade belt, and pours a thousand feet for you", and there is also a saying in "Rather know the people in the grass, there is a dragon spring under the waist" in "Giving the Shogunate Servants at the Water Army Banquet". ”

After a pause, Chen Songcai continued: "Longquan has the meaning of the sword, it may not refer to the one of the ten famous swords, but the sword forged by Longquan later, however, Li Bai and Li Shimin are related to the same clan, both are descendants of Li Wei, Li Bai is the ninth grandson of Li Hui, Tang Taizong Li Shimin is the eighth generation grandson of Li Hui, Li Shimin is Li Bai's father, Li Bai may also have seen or worn the seven-star Longquan sword forged by Ou Yezi and the two great sword masters!"

Liu Yiyan and Yang Hao nodded again and again.

I'm afraid that's the only way to explain it!

The Longquan Sword is famous all over the world because of Li Yuan, and Longquan has also become synonymous with the sword.

Now the Longquan sword forged by Huaxia has become world-famous, and in the martial Tang Dynasty, I am afraid that it will also be imitated by the world because of Li Yuan's wearing!

After all, the sales of celebrity endorsements are so terrifying now, let alone the emperor!

Liu Yan sighed: "I can't imagine that this Tang poem contains so much information! A poet immortal is not so simple, not to mention a poet saint!"

When I read Tang poems in the past, I never thought deeply about the stories behind the poems, and it seems that I have to go back and read them deeply!

Hearing Liu Yiyan mention the poet saint, Chen Song couldn't help but float an interesting story between the two people in his heart, and said happily: "This poet fairy and the poet saint are fun!"

"Fun?"

Liu Yiyan and Yang Hao couldn't help but be stunned when they saw Chen Song's unbearable look.

"yes!"

Chen Song smiled: "Li Bai has passed Du Fu!"

"Isn't it!"

Liu Yiyan and Yang Hao were so surprised that they couldn't keep their mouths together.

This poet immortal has also pit the poet saint?!

Yang Hao hurriedly asked, "What is the matter?"

"The incident actually happened when Li Bai was 44 years old and Du Fu was 33 years old!"

Chen Song thought for a while and said: "The previous Li Bai had already achieved fame, and his prestige and reputation had long been crowned in the United States, but that year Li Bai suffered a major setback in his career, and was given money by Tang Xuanzong, to put it bluntly, Tang Xuanzong told Li Bai that he was not the prime minister, and gave him a large sum of money, so that he should get out of here!"

"The poet immortal Taibai, who had just been frustrated in the court, was ready to go back to practice his way of immortals, and after arriving in Luoyang from Chang'an, he didn't expect to meet Du Fu in Luoyang. ”

At that time, Du Fu was not the poet we knew, Du Fu was not bumpy, he liked to travel, traveled to Wu Yue, Qi Zhao, Song Zhong and then traveled to Qi Zhao, and also made many friends, high-spirited, can be called a grand tour! It can be said that Du Fu at that time was still a little-known little minion, when he was preparing for the exam in Luoyang, he heard that the idol Li Bai came to Luoyang, but he was very happy, as a fan of Li Bai, he naturally went to see him. Li Bai heard that there was a little fan brother who asked to see him, so he gave Du Fu a face, and after meeting, it was terrible!"

Chen Song almost couldn't help but laugh out loud when he said this.

Yang Haozheng listened with relish, and when he saw Chen Song stop, he hurriedly asked, "What's the problem?"

Chen Song took a deep breath, held back a smile, and continued: "I don't know if Li Bai is bragging well, or really charming, anyway, let him admire Li Bai to death, let him listen to Li Bai's words, and follow his eldest brother Li Bai in the summer, starting from Luoyang, Henan, along the Yellow River to Kaifeng, and from Kaifeng to Shangqiu, and then from Shangqiu to Shanxian County, Shandong......"

Chen Song suddenly smiled at Yang Hao and asked, "What do you guess the two of them are doing?"

Liu Yiyan and Yang Hao both shook their heads and said they didn't know.

Chen Song couldn't help but smile and said, "Looking for immortals...... Picking fairy grass...... Refining the elixir!"

Liu Yiyan and Yang Hao laughed dumbly when they heard this!

Chen Song stifled a smile and continued: "Halfway through, they also met a homeless man, Gao Shi. ”

"Gao Shi, one of the four poets of Biansai?"

Liu Yan looked at Chen Song with some surprise.

"That's right, it's him!"

Chen Song took a deep breath and said: "But at this time, Gao Shi has not yet become a famous poet of Biansai, and his life is not very good, plowing the fields and fishing, and living a very hard life, as soon as these three people meet, they will go straight together!"

"So, the team changed from two to three, three people from summer to autumn, looking for immortals, picking fairy grass, refining elixir, the three of them were unkempt, none of them became immortals, Du Fu began to say I don't do it, brother, I want to go back! Hahaha......"

After Chen relieved himself in one breath, he couldn't hold back anymore and laughed out loud.

Yang Hao laughed out of tears.

Even Liu couldn't help but smile at a glance.

Yang Hao smiled breathlessly, wiped the tears from the corners of his eyes, and asked, "Are they really asking for immortals?"

Chen Song breathed a sigh of relief before he said: "According to records, in the summer of 744 AD, Du Fu met Li Bai in Luoyang, and the two met to travel together in the "Liang Song" (now Henan). There are also Liang Song tours, and Fang period picks up Yao grass. ', where Yao grass is fairy grass. The following year, the two traveled to Qi Zhao together, which is now Hebei and Shandong, until the autumn separated, Du Fu wrote the Seven Uniques "Gift to Li Bai", in which "Autumn comes to Gu Shang Piaopeng, and Ge Hong is not ashamed of Dansha" means that the two of them have not succeeded in learning the Tao, so they are ashamed of the famous alchemist Ge Hong. ”

Liu Yiyan nodded and added: "Du Fu also wrote poems such as "Looking for Fan Ten Seclusion with Li Shibai", "Pregnant Li Bai in Winter", "Remembering Li Bai in Spring" and other poems, which can also prove that he has a very close relationship with Li Bai. ”

"This history and poetry are so fun, isn't it?"

Yang Hao had the urge to study Chinese history and poetry.

Liu Yiyan sighed: "Although this is the case, the romantic feelings of the ancients are really admirable, and it is worth pondering for everyone in today's impetuous society!"

Yang Hao and Chen Song nodded as if they didn't understand.

Liu glanced at the two of them with a smile and said, "It's not early, let's have lunch first." ”

"Okay, master!"

Yang Hao responded obediently.

Liu Yi nodded, turned around and walked towards the small courtyard and said, "It's my turn to talk to you in the afternoon!"

"Master, are you going to teach us something new in the afternoon?"

Yang Hao hurriedly followed behind in surprise.

"Yes, Master Liu, what are you going to teach us?"

Chen Song also happily followed quickly.

Speaking of which, during this time, both of them were practicing color discrimination under the lamp, and Liu didn't ask much at a glance.

"Teach you how to look at the fog on the jadeite rough!"

"Master...... But I'm not fully proficient in color discrimination under the lamp."

"It's out of the way, it's all under the lamp. ”

......

Midday.

Lazy sunlight shone into the room full of samples.

Liu Yiyan asked Chen Song and Yang Hao to light up the light to distinguish the green hue in the rough stone, and nodded with satisfaction after reading it: "You have learned to distinguish the green hue now, but green is a sensitive color of the naked eye, and it is normal to learn quickly, as for other colors, you can also practice slowly like this!"

"Yes, master!"

"Thank you, Master Liu!"

Chen Song and Yang Hao were overjoyed when they heard that their green hue had passed.

Yang Hao was even more happy that his swollen eyes narrowed into a slit!

Liu Yiyan smiled: "Actually, there is a little trick for this color discrimination." ”

"Master, why didn't you say it earlier!"

Yang Hao and Chen Song suddenly looked at Liu with some resentment.

"If you said earlier, your basic skills would not be solid!"

Liu glanced at the two of them and said, "And I'll tell you after you learn how to distinguish tones, it will be twice the result with half the effort." ”

Yang Hao couldn't wait to ask, "Master, what kind of skill is that?"

"By looking at the color roots of the jade!"

After a pause, Liu Yan Yan continued: "However, it will be easier to distinguish the hue of jadeite when used on finished jadeite products and jadeite wool without weathered shells. ”

Yang Hao asked, "Master, what is the color root of jadeite?"

Chen Song also glanced at Liu curiously.

I have heard the word color root several times, and the earliest time was when I heard it from the jade master Tu Tong.

Even though I've seen a lot of samples during this time, I still can't understand it well.

"It is in the finished product or jadeite wool of jadeite, see the dot or strip, darker color, slowly gradient transition to a relatively light color, this kind of darker color is called the color root, generally can be considered in this way, that is, the color of the jadeite is more concentrated in the place called the color root of the jadeite. ”

Liu Yiyan explained: "Because the color of jadeite is formed due to the invasion and long-term impregnation of color-causing minerals over millions or even tens of millions of years, in the process of infection, due to long-term underground high pressure or natural impact pressure, the place where the crystal is slightly coarser and the texture is slightly looser in the jade texture often becomes the place where the color-causing minerals are infected along the set, and may spread to other parts along the color-affected place. To be precise, chromium, the most important element in black minerals, displaces other elements and appears green after diffusion, and the green becomes darker around the black minerals, and these residual black minerals are also called color roots. ”
