On October 27th, the third year of Sejongâs reign (1421), Hyang was installed as the Crown Prince. Finally, he was officially recognized as the successor of the next reignânot only a prince anymore.
The others didnât know, but the night when the installation ceremony ended, Hyang tightly clenched his fist, as he was very happy.
âFinally, the time has come!â
âLetâs see⊠the policies that our king has carried out till this day areâŠâ
Hyang folded his arms after pushing back the scripture on the table. He was reviewing all the policies that had been carried out by King Sejong in his head.
âIn the first year after the coronation, it was a mess because Prison of Kang Sang-in happened, so there is nothing except a reshuffleâŠâ
After that, King Sejong steadily carried out his policies.
He gave tax exemption for the starving farmers in Gangwon-do; he met the officials dispatched in the provincial by himself; he expanded the Hall of Worthies and added Four Books (the Analects, Mencius, Doctrine of the Mean, Great Learning) as an exam subject for the military. After that, the Invasion of Daemado Island took place.
Among King Sejongâs policies, the policy that attracted Hyangâs attention was related to salt.
A policy that refused the salt farmersâ request to reduce the tax on salt and simultaneously expanded the monopoly of salt was being executed.
âExclusive right to sell salt⊠well, it really makes money.â
King Sejong paid as much attention to national prosperity and defense as he did to the public welfare. The most important thing in national prosperity and defense was the security of the budget. The exclusive selling right of salt was used for this security of budget.
To resolve the national budget problem, King Sejong had sent a credential to the Ming Dynasty. The content of the credential was about the bowl made of gold and silver to be excluded from tributary items.
However, Hyang didnât give a good evaluation.
âItâs fine to exclude gold items from the tributaries, but the problem is, that much of the tributary is being stolen by the envoy. What should I do about thisâŠâ
Besides that, there were many that Hyang thought to be problems. However, the most concerning was the land and smuggler problem.
âFor the problem of the great landlords and ministersâ opposition to the land possession limit, the tax system needs to be changed. And then the smuggler⊠not to mention the trade, this part of contempt in the business itself needs to be changed firstâŠâ
Hyang let out a long sigh as he considered other various kinds of minor improvements and solutions.
âI can come out with several solutions, but there is one big constraint for that⊠the government of Joseon has no money. Ah, has no gold.â
âGoldâ was the ultimate solution Hyang had thought of.
Money circulation is essential in order to certainly improve the land system and taxation system. However, the circulation of the money continually failed. King Sejong will try again sooner, but according to history, he will fail.
However, the reason money circulation keeps on failing is that the government couldnât guarantee the existence of the currency through the new method of money-making.
Most of the money-making methods by the rich such as local landlords and high-ranking officials are through goods such as grain and cotton. However, the lifespan of things like grain and cotton is short. Therefore, in order to preserve their wealth for a long time, the rich change the goods into something such as gold and silver.
In order to seize the wealth accumulated by the rich, radical taxation policies and land policies are necessary.
However, executing radical policies like this will arouse the richâs opposition.
To suppress this opposition, the central governmentâin particular the Kingâmust possess a definite military power.
However, possessing a certain military power meant that it required an equally large budget. What to do to solve that problem?
Hyang had kept thinking over and over again and showed a dejected expression.
âNo matter how much I revise the plan, if I canât resolve the first problem, which is money, I will only get back to the same repeat mark. Only the kingâs decision could solve this motherfucking repeat mark. Luckily, this is possible for King Sejong the Great. My role is⊠seasoning him?â
Hyang nodded at his conclusion.
âIâve become the crown prince, but since I was just an eight-year-old, my authority is still weak. Itâs best to throw something like bait occasionally. And the start isâŠâ
Hyang stared at the brush in the holder on the side of the desk.
[December 10th in the 3rd year of King Sejong. The crown prince made a golden brush and offered it to the king. The king tried the brush and praised it for its convenience in rapid writing. The crown prince petitioned the king for the historian and others who needed to write fast to use the brush and the king gave his permission.]
Around the middle of November, Hyang went to the arsenal bureau(1)). The highest senior ranking official among those who were in charge of the arsenal bureau hurriedly came out when he heard the news of the Crown Princeâs visit.
âI greet His Royal Highness the Crown Prince.â
âYouâve worked hard.â
The senior official lowered his head even more at Hyangâs praise.
âIs it fine for me to look around for a while?â
When Hyang was about to take a step under the guidance of Lee Chang-hoâthe senior official of the arsenal bureau, the craftsmen of the arsenal bureau who had heard about the Crown Princeâs visit came out and showed their respect.
âWe greet His Royal Highness the Crown Prince.â
âThank you very much for your hard work. Iâm really thankful because you guys are here so that the defense of our Joseon becomes stronger.â
The craftsmen who were prostrating themselves were touched by the crown princeâs praise and answered.
âWe donât deserve the Crown Princeâs praise.â
âIt is really an honor for us!â
The craftsmen, who were touched by the praise of someone as high as the sky, took a lead and guided Hyang to every corner in the arsenal bureau.
There were some reasons for Hyang to visit the arsenal bureau, but the biggest reason was the arsenal bureau is the place to make weapons.
âWeapons, explosives⊠from now on Iâll often come here, so itâs better to leave a mark here. I do want Jang Young-sil, but he is from the royal tailor. He is a high scholar and backer of King Sejong, soâŠâ
Hyang pushed back his regret of Jang Young-sil while he was looking around the arsenal bureau and got down to business.
âWho is the most talented at handling gold and iron in this place?â
âThatâs right. There is something he needs to make.â
âSomeone profound in handling gold and ironâŠâ
At the Crown Princeâs question, the senior official of the arsenal bureau pondered over all the blacksmithsâ faces. The senior official who was looking for someone who was suitable enough suddenly thought of one person.
âThere is someone who is decent enough.â
Not long after, a middle-aged blacksmith entered the senior official room after got summoned.
âDid you call for me?â
âI did. Blacksmith Gong, the Crown Prince said he has something to order.â
When he heard Crown Prince Hyang had requested for him, Blacksmith Gong courteously showed his respect to the Crown Prince.
âThis lowly person greets His Royal Highness the Crown Prince.â
âPlease donât lower yourself. How could a blacksmith of the arsenal bureau in charge of our Joseon national defense be such a lowly person?â
âTha, thank you, Your Royal Highness!â
Blacksmith Gong prostrated himself because he was very touched by Hyangâs praise.
âRaise up. There is something I urgently need your help with.â
âPlease give me your order! I will do it by risking my life!â
âThe status of a blacksmith of the arsenal bureau wouldnât be low, but how much did they suffer thatâŠâ
Hyang drew a bitter smile because the response of Blacksmith Gong was more than he had expected. Then he took out a paper from his sleeve and handed it out.
âCan you make it this way?â
âThis is an item that will replace the brush.â
The thing that Hyang gave out was a blueprint of a pen nib.
Blacksmith Gong examined the blueprint that was given by Hyang with a serious face. Then he began to talk.
âIt holds the ink, but the ink will flow down while it is being used⊠the point is the ink cannot flow out all at once; and if it doesnât flow out at all, that is also unacceptable.â
âOn top of that, it shouldnât get stuck in the paper, so the bead that will be installed at the tip of this nib should be round. One more, this slit where the ink flows out. There is no use if itâs too wide or too thin. Blacksmith Gong, how thin is the slit you can make?â
Blacksmith Gong pondered over Hyangâs question for a while before answering.
âWith all my capability, I could make it to five mo.â
When Hyang wondered as he tilted his head, the senior official of the arsenal bureau by his side explained.
âIt is five mo of a chon.â
Upon hearing that, Hyang calculated inside his head.
âA chon is the same as a chi, a chi is around 3cm, because it is hal-pun-ri-mo⊠1 of 10000? That is possible? Anyway, it is approximately around 0,15mm? Is this possible manually?â(2))
Hyang was dumbfounded at the unexpected result, then quickly set his expression right and asked a question.
âThere is a possibility that youâll not only make one but dozens. On top of that, the time for you to make it isnât months but as fast as possible.â
Blacksmith Gong calculated over Hyangâs question, then answered.
âBecause it will touch water, we must not use an iron but gold or silver, so itâll not get rusty. And because it will be turned into thin plates, if I make the mold correctly then it is possible for me to make 20 in a day. If there is a problem, then it is that slit.â
Hyang rushed into calculating after blacksmith Gongâs answer.
âA sharp lead around 0.5 milli is okay, right?â
âWhen used to write, the thickness of the stroke can be a bit more than 1 ri.â(3))
âThen, Iâll try to set the slit standard to be 1 ri for now.â
âSo when can I see the end product?â
âIf you give me two days-.â
âIâll give you three days. So, can you show me the best result?â
âYour wish is my command.â
On the way back to the palace with the escort from the officials of the arsenal bureau, Hyang turned to the eunuch attending him.
âYes, Your Royal Highness.â
âIs there any property that I can use personally?â
âI will check on the Royal Properties Office, Your Royal Highness.â
Three days later, Hyang visited the arsenal bureau once more.
Blacksmith Gong gave a fine wooden box containing five pen nibs to Hyang.
âI made it with five types of thickness. Please choose the thickness you like.â
Hyang wrote on the waste paper near him and compared the result. Then he chose the nibs he liked.
âMake 100 for this one. However, for the 10 of themâŠâ
Blacksmith Gong carefully noted down the options Hyang talked about and quickly replied.
âIt is possible, Your Royal Highness.â
âAnd can you carve a plum flower in the body of this golden brush?â
âI can, Your Royal Highness.â
âThen, how many days do you need?â
âTen days is enough, Your Royal Highness.â
Hyang thought over Blacksmith Gongâs answer for a moment, then made a conclusion.
âI give you an extra two days to do that. Instead, there shouldnât be any defects. Can you do it? Iâll offer it to the King.â
âI will make it with no single defect in it.â
âAll right, I entrust you with this. Ah, you should keep this as a secret until I offer it to the King.â
âYour wish is my command.â
As he finished his business, Hyang left the arsenal bureau with a joyful expression. The arsenal bureau senior officialâLee Chang-ho, turned to face Blacksmith Gong after sending Hyang off.
âHe is someone who is completely out of his age.â
âI agree, Sir. I heard this year he is eight years old, but looking only at his speeches and manners it is possible to mistake him as a man in his prime age.â
âWell, thatâs true, and you got a great deal.â
Lee Chang-ho couldnât hide his envy as he looked at the paper in Blacksmith Gongâs hand.
Before Hyang left the arsenal bureau, he left a thank you note for Blacksmith Gong.
âThe Best Artisan of the Promising Joseon. Lee Hyang, the Crown Prince.â
Blacksmith Gong trembled with emotion when he was handed a piece of paper with a stamp of the Crown Princeâs palm next to his name.
âI will tell the wood factory supervisor and ask him to make the coolest picture mounting. This is something that is worth being an heirloom.â
Two weeks later, Hyang visited King Sejong, who was in the middle of a discussion with the officials. During his visit, Hyang presented the pen nib and pen barrel to King Sejong.
King Sejong fixed the nib to the barrel and tried to write with it while listening to Hyangâs explanation. He was very satisfied.
âWhat a piece of work! This is very comfortable to use and above all, the arm and wrist are comfortable! You made a very good item, Crown Prince! You did splendid work, Crown Prince! Historians, record nicely what the Crown Prince did today!â
âI donât deserve your generous praise.â
Hyang remained humble at King Sejongâs praise. King Sejong was looking at the nib and the barrel that was decorated with lacquerware before he saw a floral pattern at the pen nib.
âIs this flower the plum flower?â
âThatâs right. I thought it was suitable as a symbol of the royal family, so I carved it.â
King Sejong used the pen in the paper once more before turning to Hyang.
âI will make good use of this.â
âIt is an honor. However, there is a favor I want to ask.â
(1) Arsenal Bureau (Gungi-gam): A bureau under the Ministry of Military Affairs that was in charge of manufacturing weapons, flags, armor, utensils, and miscellaneous items. Sometimes called Gungi-si and at Gojongâs era called as Gigi-guk.â»
(2) Hal-Pun-Ri-Mo: An ancient unit of measure(?) Sometimes it is still used tho. 1 hal = 10 pun = 100 ri = 1000 mo. But since hal mostly counted as 10-1, 1 mo counted as 10-4. 1 chon = 10 pun = 3.03cm. So, 5 mo of 1 chon which is 3.03 cm = 30.3 mm/1000*5 = 0.1515 mm.â»
