Shangheling, experimental factory.


    It has been six days since Arthur came here last time, and now the steam engine he has been waiting for has finally been assembled.


    "Sir, is this the steam engine?"


    In the factory building, looking at the behemoth assembled with copper and iron in front of her, Leah asked in surprise and curiosity.


    As Arthur''s secretary, of course, she knew about the steam engine, and she helped sort out the drawings of the behemoth.


    But the feeling of drawings and real objects is completely different. It''s better than drawing a sun on the drawings, just like seeing the sun with your own eyes.


    "God, my dear friend! How many pieces of iron and copper do you have to use this thing! It looks like a magical thing - no, no, no! Wizards don''t have gold coins to make such a thing!"


    The birth of the steam engine will be of great significance. Arthur specially asked Leia and Gustav to witness this historic moment.


    "It''s ok if you want to understand it like this, but it''s not witchcraft, but the power of science!"


    Arthur agreed to be excited. In his eyes, this seemingly rough steam engine, the size of a living room, exudes unparalleled beauty - the beauty of industry and machinery!


    "Sir, can this thing really move?" even Thorne asked curiously, looking at the iron pimple in front of him.


    This thing called steam engine is all made of metal. If you want to move the whole thing, I''m afraid you need at least a dozen horses to pull at the same time.


    "Not only can it work, but also it has infinite power!" Arthur smiled with a proud tone. "With it, many heavy labor requiring human and animal power can get a steady stream of power, and it will never be tired. As long as there is steam, it can work all the time!"


    "My friend, is this stove like an iron bucket? God, I''m not questioning you, my friend. Constant power, it''s tempting, but steam, are you sure that thing can make it move?"


    You are questioning! Looking at Gustav, Arthur smiled mysteriously and said, "you''ll know later!"


    "I can''t wait!"


    At Arthur''s command, the workers began to make a fire and fill the steam chamber with water.


    About ten minutes later, the water was boiled and there was a tumbling sound. Then there was a sound of fried beans in the cylinder. Arthur knew that it was the sound caused by the heating of the cylinder block.


    The onlookers were all watching the big guy in front of them, with both the doubt of "just boiling water" and the excitement of looking forward to major events.


    With the passage of time, the cylinder was soon filled with hot steam. Then, under the eyes of everyone, the piston pushed the connecting rod and began to move outward slowly.


    "Move! Move the power!"


    "Move, this thing starts to move!"


    "Steam, steam pushes the iron bar to move!"


    ……


    At the moment when the connecting rod moved, the Knights couldn''t help shouting, while Arthur and Leah raised their heads and looked at them with flashing eyes.


    When the piston pushes the connecting rod to the top, the other connecting rod on one side pulls the sliding valve, and the hot steam then pushes the piston inward. The two connecting rods come and go back to quickly run the linked flywheel.


    After several round trips, with the continuous increase of power, the flywheel runs faster and faster. When the speed reaches the peak, the machine emits bursts of roar, and the exhaust port spits white gas.


    In an instant, the originally cold huge machinery woke up like a beast and stood in front of everyone with an unstoppable momentum!


    "This, this..."


    Looking at the huge iron wheel rotating rapidly in front of them, the knights were shocked and couldn''t even say a word.


    Originally, they were surprised enough to see the steam make the iron bar move, but now looking at the iron wheel rotating like a feather and feeling the air wave brought by the rotation of the iron wheel, they really realized what kind of huge power the seemingly bulky machine in front of them has!


    "Success! Ha ha ha..."


    After observing patiently for a while and finding no abnormality, Arthur finally couldn''t restrain his excitement, raised his fist clenched arm, and gave out excited cheers and laughter.


    Looking at Arthur who raised her arms and cheered, Leah held her hands on her chest with a happy smile on her face. If she didn''t worry about too many people around, she would shout out with Arthur.


    Gustav looked at the steaming steam engine with his mouth open. He was stunned for a long time before he came close to Arthur.


    "My friend, you just said that this thing can replace human and animal power. What can it do?"


    "What are you doing? Ha!" Arthur said excitedly, looking at Gustav with curiosity in his eyes. "He can do whatever you want him to do! Whether it''s drainage, transportation, iron smelting, forging... He can do anything that requires heavy labor!"


    "Think about it. We only need to build a conveyor belt to complete the iron ore transportation that used to take two or three hundred slaves! Similarly, a work that used to take ten days to complete may be completed in one day!"


    Gustav didn''t know what the conveyor belt was, but Arthur''s description of "working in ten days and completing it in one day" made him feel refreshed in an instant, and his curious eyes immediately turned into surprises.


    "Then the goods we produce..."


    Arthur smiled and nodded before he finished.


    ……


    ……


    After leaving the experimental factory, Gustav did not return to Shanghe Town, but came to Lingfeng castle with Arthur.


    The completion of the steam engine is only the beginning. According to the current situation in Shanghe Town, one steam engine is obviously not enough. Moreover, the use of new power needs detailed planning. For example, Arthur''s conveyor belt needs to be planned wherever and how to build it.


    In addition, the operation of the steam engine also requires special workers, as well as the maintenance of the steam engine.


    In the study, the servant had just sent some fruit pies and some fruits, plus a jar of low alcohol drinks. Arthur was asking Gustav, Thorne and Leah to enjoy them together. When he planned to eat and talk, he learned that Mr. Boye, who had returned to the city, hurried into the study.


    Arthur was in a good mood. Looking at the arrival of the bachelor, he smiled and said, "master Boye, let''s have a drink! Have some food by the way!"


    Looking at the people preparing for the "dinner", especially seeing Thorne participating in it, Mr. Boye was stunned and immediately guessed that something happy must have happened - Arthur rarely drank.


    "Thank you for your hospitality, sir," said the bachelor with a smile, handing the letter to Arthur. "This is an urgent letter from town. Please have a look."


    Arthur reached out and took the letter. In addition to the fire paint, there was a red word "urgent" printed on the upper left corner of the letter.
