Chapter 221


    Two months had passed since the Challenger was safelyunched. From this time, Sejong began to gradually urge the Ministry of Military Affairs and Hyang.


    Is the Challenger still not ready?


    Are they still under training?


    Every time Sejong urged, Jo Mal-saeng and Hyang had to give the same answer.


    The naval forces training level is still insufficient, so they are training day and night, forgetting about the time.


    A little more time is needed.


    Oh my~.


    Every time he heard the answers from Jo Mal-saeng and Hyang, Sejong did not hide his impatience.


    Isnt the establishment of the 1st Ocean-Going Fleet almost finished? Yet, the preparations for Ship No. 1, the Challenger, are still not done?


    At Sejongs reprimand, Hyang immediately answered.


    The hull form of the Challenger is different from the Korean ships that have been used until now, so it is taking time to master its characteristics. Those who have mastered the characteristics of ocean-going ships through the Challenger will be the core personnel for the ships that will follow, so we are taking every precaution in training.


    Its taking time because the hull form is different Tsk.


    At Hyangs exnation, Sejong had to click his tongue. Seeing this, Hyang continued.


    Yes. Fundamentally, the ships that form the backbone of our Joseon Navy have been t-bottomed ships for generations. However, the Challenger is a sharp-bottomed ship. Speaking of this sharp-bottomed ship


    ***


    Hyangs exnation was not a mere excuse.


    Since the Goryeo Dynasty, t-bottomed ships had been the mainstream for Korean ships. This was because the main area of activity for Korean ships was limited to the West Sea and the South Sea. Therefore, t-bottomed ships, which focused on safety rather than speed overall, became the mainstream.


    In the West Sea, which had a strong character of a calm ind sea and arge tidal range, and the South Sea, which had aplex coastline and strong tidal currents, t-bottomed ships with a shallow draft, small turning radius, and good bnce even when stranded on tidal ts at low tide were advantageous.


    However, sharp-bottomed ships like the Challenger had a deeper draft and a wider turning radius, unlike t-bottomed ships.


    Also, due to the characteristics of sharp-bottomed ships, if they were to be stranded on tidal ts, they would immediately tilt and run aground.


    Because of these differences, it took more time for the Joseon Navy to handle the ships.


    However, Hyang had no choice but to insist on sharp-bottomed ships.


    This was because when going out to the ocean, the advantages of t-bottomed ships would be disadvantages, and the disadvantages of sharp-bottomed ships would turn into advantages.


    ***


    Sejong, who was listening to Hyangs exnation, pointed out the problem.


    Then, the most important thing would be themander who will move the ship


    I have already reported


    As Hyangs words slightly trailed off, Sejong searched his memory.


    Sejong, who had to find the memory he had deeply buried while dealing with dozens to hundreds of reports every day, finally remembered who the captain of the Challenger was.


    We promoted and appointed Assistant Commander Oh Ha-seok as Manho (, Commander of 10,000 men), right?


    Thats right. We appointed him because he had experience sailing the ocean and had mastered the characteristics of sharp-bottomed ships through the ships of the Hui people.


    [TL/N: Sharp-bottomed ships or sharp-schooner are ships with sharp curved midsection on its /uploads/monthly_2020_04/image.png.bd8d7c738d1bd05b6a6c3cb86e8e4280.png ]


    Hmm I see.


    At Hyangs exnation, Sejong nodded his head.


    ording to his memory, those who had safely traveled to Aden with Oh Ha-seok were all assigned to the Challenger.


    They would gain experience in ocean navigation through the Challenger and then move on to be captains of the newlyunched ocean-going ships.


    In the end, Sejong had no choice but to take a step back.


    It is natural to be cautious as it is a matter upon which the future of our Joseon depends. However, we must prevent the dy of progress by putting in too much effort.


    I will keep that in mind!


    Hyang bowed his head and answered at Sejongs words. However, Hyang kept grumbling inwardly.


    Your Majesty! I am more urgent! Im saying we need to assemble the fleet as quickly as possible to send them to South America!


    ***


    Once the fleet is assembled, we must send it to South America under any pretext.


    Hyang muttered while examining the report recording the training situation and improvements of the Challenger.


    What we will bring from South America is not just gold or silver. There is something even more important. What we will bring from South America are potatoes, sweet potatoes, and rubber. No, even if we skip everything else, we absolutely need rubber.


    For Hyang, rubber was an item that he had to obtain at all costs. Hyang tapped the desk with his fingers and muttered.


    If we can just get rubber, we can warp this Joseon right away.


    ***


    The starting point for Hyangs desperate desire for rubber was the steam engine.


    Connecting the pipes through which high-temperature steam passed required copper gaskets. However, the steam engines currently being continuously improved in the research institute and Area 51 required copper gaskets for all parts that needed sealing, even if they were not exposed to heat.


    If its like this, the manufacturing cost will be too high, even if I dont know about the lifespan.


    It was not just a matter of the unit cost of steam engines. As more and more devices were being made, the need for rubber was increasing.


    The water hose attached to the water pump used by the Geumhwa-gun (Firearms Corps) to spray water towards the fire also needed rubber.


    The water hose made of thick and tough cotton cloth had a short lifespan, and its water discharge performance and pressure resistance were poor.


    If the pressure increased even slightly, the hose made of cotton cloth would burst first.


    As a result, the centrifugal pump mounted on the water pump could not be utilized to its 100% capacity.


    That was not all.


    Rubber was also needed for the housingplex for homeless officials, which hadpleted its design and only had thend purchase process remaining.


    The part where rubber would be used in the newly designed housing was the well pump. Hyang, who remembered the well pump installed in the kitchen sink in the Western movies he had seen in the 21st century, was agonizing over how to apply it.


    I remember the structure well, but the problem is the packing, as expected.


    The piston of the well pump, which was one of the few remaining in rural viges of Yangsan, had to have a packingponent made of rubber.


    Of course, it worked even when using a copper-made, hinge-type packing, but rubber had to be used for better performance.


    It could be somewhat substituted with wood, bamboo, or even paper, but there was the issue of decay.


    However, what made Hyang desperately want rubber was to create a device he considered most important along with the steam engine.


    If this ispleted, Joseon can develop not just by leaps but at warp speed!


    What Hyang was determined to make was a generator.


    ***


    In the 21st century, it was an era where survival itself would be a problem without electricity. Being so ustomed to the existence of electricity, Hyang absolutely could not give up on it.


    Its not like I dont know the structure of a generator


    During his high school days in the 21st century, Hyang had the experience of making a model steam lotive that actually moved by heating water and won a prize in apetition.


    Of course, Hyang did the overall system design and conceptualization, while his science-track ssmates did all the actual numerical calctions.


    At that time, it was mutually beneficial. Hyang, who was immersed in steampunk, was happy to indulge in his interests, and his science-track ssmates could acquire a card that would be advantageous when applying to university.


    Of course, Hyang had to receive both praise and scolding from his parents at the same time.


    Itsmendable that you won an award. But what will you use this award for as a humanities student!


    Although he was scolded like that, the following year, Hyang made and submitted a model of a generator connected to a steam engine.


    Therefore, Hyang had definite knowledge about generators.


    Thats why Hyangpleted the basic design of the generator as the steam engine was being made, but he had to stop there.


    The problem is the electric wire. The electric wire


    To be precise, it was the problem of the insting material to wrap the electric wire.


    Of course, electric wires could be made even without rubber.


    For simple instion, it would suffice to wrap the wire with paper or cloth soaked in oil.


    In fact, the wires inside the radio used by the Japanese military during World War II were wrapped in oil-soaked cloth.


    Hyang, who confirmed the relevant records through the inte, clicked his tongue.


    They had rubber-producing areas under their control, yet they made wires like this? No wonder they lost.


    Anyway, since there were relevant records, Hyang had thought of borrowing this method, but he soon abandoned the idea.


    It was because of the Great Fire of Hanseong, the devastation of which he had witnessed with his own eyes.


    Most of the houses have thatched roofs and are made of wood, and the wires are soaked in oil It will burst into mes.


    Hyang gave up on the idea of using oil-soaked cloth or paper as an instor.


    ***


    In addition, there were numerous devices whose performance would dramatically increase with the use of rubber, from water bottles to shoes.


    Hyang had thought of making synthetic rubber, but unfortunately, he did not know the process.


    Therefore, Hyang wanted the rapid deployment of the ocean-going fleet more than anyone else.


    Thats why, while soothing Sejongs impatience, Hyang was internallyining.


    If theres anyone here whos as anxious as me,e out and show yourself!


    ***


    Returning to his office, Hyang let out a long sigh.


    Phew~. For the ocean-going fleet to function properly, we need at least 15 ships. And thats just warships.


    Hyangs n was to operate the fleet by having 3 ships go to the Middle East, another 3 ships return from the Middle East, and another 3 ships rest and undergo maintenance.


    After allocating 9 ships in this way, out of the remaining 6 ships, 3 would be on standby as a reserve force, and the other 3 would be sent to the New World. This was Hyangs scenario.


    Fortunately, sending them up north and having theme down south is safer and can receive more reliable support than having them cross the Pacific Ocean unconditionally.


    Hyang spread out the world map he had made  which was nothing more than a rough sketch, regardless of scale  and checked his n.


    Starting from Wonsan, passing through Sakhalin, using the Kuril Inds as a signpost, passing through the Kamchatka Penins, crossing the Bering Sea from there to arrive in ska, and then going down along the west coast of North and South America will ensure maximum safety while moving. Of course, we have to be careful that the northern route bes inessible as soon as winteres Then, will the first forward base be the Kamchatka Penins? Or divostok? Its not Russian territory now, so what should we name /92/243492-050-0340B2AD/Locator-map-Kamchatka-Penins.jpg


    Looking at the map and fantasizing alone, Hyang suddenly realized the reality and burst intoughter.


    Hah! Its like a dream. Were currently struggling to secure wood to build ships, yet


    ***


    The state of Joseons forests during this period was not easy.


    Although coal was being supplied more and more, many trees were still being cut down for cooking and heating.


    Therefore, efforts were being made to protect the forests and restore the destroyed forests from the early days of the founding of the nation.


    However, trees do not grow rapidly, and the need for quality wood was not limited to shipbuilding, so the supply and demand of wood were not smooth.


    Therefore, even when building turtle ships, there was a saying, Every time a turtle ship is built, a forest disappears.


    Knowing this situation, Hyangughed in dismay.


    The conclusion is that we must secure the Siberian forest zone. Dense and strong wood is the best for building ships. Why do you think French ships of the line and American frigates were called ruffians?


    Recalling the movies and inte records he had seen in the 21st century, Hyang reaffirmed the need to secure the Siberian forest zone.


    The problem is that the stabilization of the pioneer areas in the northeast is not yetplete. Roads will be built and people will enter only when this area is stabilized


    Continuing to check the situation, Hyang let out a long sigh.


    Phew~. When will that ever happen
