"Get out of the car, guys! Here we are, and this is the residence of the Emperor of the Machines. Zhang Yue opened the car door as she spoke.

"What kind of guys are these black guys?" Kafka asked curiously.

"Robots." Zhang Yue replied casually.

"Robots? Is this really a mecha too? It's incredible, they look more like humans than these metallic sheen. Kafka lamented.

"Don't doubt what you see, the people who live in this mechanical eagle castle are the world's number one mechanical geek, and the name of the mechanical emperor is not in vain."

"Today was an eye-opener!" Kafka said as he carried the warden out of the car.

Except for him, all of them are women, and women can't be allowed to do such things, so Kafka is naturally duty-bound.

After just a few days of recuperation, the warden looked much better. The medicine given by Madame Peacock was very effective, and the warden's body recovered quickly, although he still looked a little weak, but compared to when he first came to the Twin Cities, he was completely like two people.

"It's really worthy of being a mechanical emperor, and his attainments in making mecha are so high." The warden had apparently heard the conversation between Zhang Yue and Kafka just now.

"What else can I tell you something more incredible?" Zhang Yue said with a smile.

"What's the matter? Don't sell it, let's get straight to the point. Kafka asked curiously.

Although the warden didn't say anything, the faint smile on his face clearly showed that he was also full of anticipation.

"These Ugin mechs are not only fully automated, but the fuselage of these mechs is not designed with fuel tanks and boilers, so they don't need to add fuel." Zhang Yue said.

"Oh! My Royal Highness, my princess, do you think that we are very good at fooling me when I am old with the warden, and will believe your nonsense? Anyone with even a modicum of physics knows that if there is machinery that can do without consuming fuel. If the energy conversion can be completed, it means that the perpetual motion machine has been invented in the world. But in this world, there can never be a perpetual motion machine. The total amount of work that can be produced by any kind of energy cannot be completely equal to the useful work, and in any case, the extra work will inevitably exist, unless it may be in God's heaven. That's what happens. Even middle school students in school know that the ratio of mechanical efficiency cannot reach 100%, and although I was born in biology, I still understand this basic common sense. Kafka said incredulously.

The warden also nodded behind Kafka, saying that this is common sense, even if the mechanical emperor is powerful, he can't break the unchangeable law of mechanical efficiency on Earth, unless he can get himself to another planet, maybe there is a possibility of breaking this truth.

"That's the magic of the Machine Emperor. All of the machines in the Mecha Eagle do not need to be fueled. Have you heard of Nikolai? Tesla Professor? And his radio streaming? Zhang Yue asked.

"Yes, but before he could succeed, he was gone." Kafka said.

"Your Royal Highness Princess, do you want to tell us that the Mechanical Emperor has achieved the wireless transmission of low-frequency electromagnetic waves? If that's the case, then the Machine Emperor is incredible. "The warden seems to realize something.

"No, although the Mechanical Emperor would like to make a breakthrough in this area, there are still many technical problems to be solved in the transmission of electric current in the air medium. Nikolai? Tesla wanted to use an electric current to break through the air to power various mechanical devices. However, it is easy to break down the air, and it is not so simple to achieve effective transmission, especially over long distances. However, the Machine Emperor has adopted a workaround. He didn't just focus on air as a medium, he thought maybe he could achieve the transmission of electricity through other media, as long as this conduction process was not noticed, then it would seem like a medium-free transmission, and what you are under your feet is the best invisible medium that the Machine Emperor has found. Zhang Yue said.

"The more you talk about me, the more confused I become, and I'm starting to suspect that it's your ability to express yourself. Or my comprehension problem. Kafka said.

"Look at the steel ground beneath your feet! These things are not just decorations, they have a much more important role. That is to provide all the machinery of the Mechanical Eagle Castle with the necessary power needed. Metal is undoubtedly a good carrier of current transmission, and the machinery here does not have fuel tanks, but instead resistors and step-up transformers are used to receive current. Zhang Yue said.

"Oh! …… I seem to understand that this means that the metal floor replaces the transmission lines and thus powers the machinery here, so the machinery here doesn't need to install bulky fuel tanks or drag a lot of connection lines, you mean? But if the ground is filled with electricity, as you say, why haven't we been electrocuted? Kafka asked incredulously.

"That's right! That's what it means, because there is a step-up transformer in the machine, the current and voltage of the metal ground are very low, and normal people can't feel it at all, just like a grain of aluminum battery. Zhang Yue said.

"I see." Kafka nodded.

"Incredible." The warden said.

"And that's not all." Zhang Yue said.

"And what else?" Kafka asked, puzzled.

"The machines in the Mechanical Eagle Fort are not in their own way, but are controlled by a unified central processing unit." Zhang Yue said.

"You mean the mechanical heart 'thinking machine'?" Kafka asked.

"Yes, that's right!" The complex setting of the thinking machine makes the national heart of each country need thousands of senior engineers, who are busy day and night to ensure the normal operation of the national heart. But at the Mechanical Eagle Castle, the Machine Emperor did the job alone. Zhang Yue said.

"He's such a genius! When I was working in the Gulag, I heard about his horrific experiments on how to combine machines with living beings, and how to achieve a natural pairing of machines and living beings through natural reproduction. I didn't expect his ability to be far more than that. Kafka lamented.

"See that golden eagle?" Zhang Yue asked.

"I've seen it from afar." Kafka said.

"That's the 'Thinking Machine' of the Mechanical Eagle Castle, and it's the real master here. Everything that happens in this place is controlled by it, and sometimes the mechanical emperor looks more like a puppet. It always makes people feel that the mechanical emperor is like the Guangxu Emperor, and this 'thinking machine' is the powerful Empress Dowager Cixi. Zhang Yue said. (To be continued.) )
