In the City of Neverwinter, Graycastle.
Ever since the news of the coronation ceremony was announced, Roland had handed over all the preparations to Barov. Barov seemed to be particularly diligent. Not only was he busy every day, but he had also invited Lady Blanche, the ceremonial officer of the old king's city, to Neverwinter. Obviously, he did not want to make any mistakes.
As for Roland himself, apart from occasionally checking the progress of the magic movie, he spent the rest of his time finalizing the internal combustion engine.
Since there was a certain error in the weights and measures of the two worlds, the prototype had to pass the stability test. Moreover, the fractionated oil was uneven, so he had to take into account the redundancy of the design. Since he did not have the means of simulating the real world, he could only make adjustments with the real thing.
From manufacturing, to experimenting, to scrapping, to improving, and to repeating. Roland felt like he had returned to his school days. Every day, he would travel between the castle and the back mountain of the North Slope, living a busy and fulfilling life of research. The knowledge that he had not touched for a long time became vivid again in the past half a month.
Of course, he did not have Anna to accompany him at that time.
What was more wonderful was that she was as enthusiastic about new things as he was.
Every time he saw her concentrating on assembling the precise parts and wiping the sweat from the tip of her nose, Roland could not help but sigh with emotion. Her desire for creation and knowledge seemed to be innate, just like her flame, scorching and pure.
This inner spirit was beyond the scope of what could be described by her appearance. He would never get tired of looking at her.
Every time she made a decisive progress, the smile on Anna's face could almost be described as the blossoming of all flowers. Roland even felt that the joy of creation was far greater for her than being a queen.
She had never concealed her thoughts. As long as they could stay together, she did not care too much about the false reputation.
Of course, Roland also knew that sometimes the reputation was not for the sake of the other party, but for the sake of the public.
As long as human beings were social animals, this was inevitable.
After marking a series of revised measurements on the blueprint, Roland put down the quill and rubbed his sore neck.
If there were no accidents, the design drawings in front of him were likely to be finalized. After all, the previous batch of prototypes had been running steadily for several days, and the accumulated working time was enough to meet the current needs.
As the second-generation power source, the principle of the internal combustion engine was not complicated. It could be regarded as the evolved version of the steam engine. The first generation of power source used steam to push the piston. No matter how ingenious the design was, it was impossible to avoid the energy loss caused by the transmission of steam. Therefore, people naturally thought of putting this power directly into the cylinder, which would certainly greatly improve the work efficiency. That was how the internal combustion engine came into being.
After mixing the oil with air, it would be injected into the cylinder, causing it to burn intensely. The expanded airflow would push the piston, and at the same time, the new fuel would be sucked into the cylinder. It sounded simple, but it was a huge project to implement. For example, steam engines had very low requirements for sealing. The gap between the piston and the cylinder block of the early products could even be stuffed with a finger. Felt and linen could be used to plug the gap. However, it was obviously not feasible for internal combustion engines.
Unlike steam engines, which were powered by external forces, the piston had to complete each cycle by itself. Therefore, if the seal was not tight, the cylinder would stop due to lack of fire.
In other words, only when the level of materials and processing technology reached a certain level could this simple principle be turned into reality. That was why the first internal combustion engine in history was actually decades later than the electric motor.
The first-generation internal combustion engine designed by Roland had a total of two directions. One was the cylinder inline type, and the other was the cylinder annular type. The former was stupid and thick, and it was made of cast iron. It was as stable as possible, and it could be put into the factory for large-scale production. The latter was also known as the star engine. Because the crankshaft was short and the structure was compact, it could be made very small, and it was very suitable for spacecraft. Overall, it was much more delicate than the former. It was made of aluminum alloy, and for the time being, only Anna was responsible for the processing.
The reason why Roland dared to develop these two products at the research and development stage was nothing more than standing on the shoulders of his predecessors. He could find a lot of information about these two time-tested products in the Dream World. Compared with the steam engine, which had gone through four generations, the starting point this time was much higher.
Coupled with the information revealed by the Senior Demon, he had to speed up his pace.
It was very difficult to defend the ground against a large number of threats from the sky, which had been proved by the expedition this time.
If the plan could be realized, human beings would be qualified to compete with their enemies in the sky for the first time.
"Your Majesty, don't move."
Nightingale suddenly said.
Roland immediately stopped and looked back.
"Is there... an enemy?"
Then he saw Nightingale come up to him and touch his head. He felt a slight pain as she put a strand of hair in front of him.
"Uh, this is white hair?" Roland did not know whether he should laugh or cry.
Although the color of gray hair was very light, these strands of hair were a little white, almost losing their luster from the roots.
"And?" Nightingale touched his hair for a while. "Have you had too little rest recently?"
"Have I?"
"You used to sleep late in the winter. Recently, you get up earlier than me and enter the Dream World at night. That can't be considered as real sleep, right?" She talked incessantly. "Yawning from time to time is a sign of fatigue. You're not even 30 years old, and your hair is already white. How can you continue like this?"
Looking at Nightingale's serious reprimand, Roland could not help feeling much lighter, and even his fatigue from work faded a little. As expected, she was not affected too much. It seemed that the agreement had played a crucial role.
"Don't worry. This is far from the limit. I've experienced it before."
"..." Nightingale looked doubtful, but she could tell that it was not a lie.
Because he was not lying. "Generally speaking, there will be a long period of palpitations, as if the chest is particularly empty. Then you will feel weak all over. You have to be careful at this time. If the reaction is strong, you will cough incessantly and even bleed — cough, cough, cough — "
Halfway through, he suddenly coughed violently.
"Hey, are you OK?" Nightingale suddenly looked nervous. She patted his back and said, "Do you need me to call Nana?"
Roland took a deep breath and said, "No... I'm fine. I just choked on my saliva."
"Really?"
"Don't worry, I..."
He turned his head and could not help but freeze for a moment. The distance between them was so close that they were almost touching. When their eyes met, both of them could not help but hold their breaths.
"Your Majesty." Just then, the office door was pushed open and Vendy walked in. "I have something to... Hmm? What are you doing? "
"Me?" Roland blinked and found that there was no one in front of him. He was half leaning back, and even without saying, he knew that it must be quite strange.
"His Majesty is practicing gymnastics." Nightingale was lying on the coffee table, leisurely chewing dried fish. "It's easy to get sore after sitting for a long time. He can try the effect first."
"I see." Vendy said thoughtfully, "Is this the gymnastics that you mentioned before that you're going to promote in the academy? But … is it really effective to put it like this? "
"Uh, it's okay." Roland awkwardly returned to his original position. He did not know why, but he felt that the innocent Nightingale was trying to hold back her laughter. "By the way, what do you want to say?"
