"Old Liu, do you know what is the fastest man-made object in history?"

When Chen Mu watched Ji Xinghe fly up in the Emperor Armor, his eyes became extremely bright, like a wolf that had not eaten meat for three years.

Old Liu looked nervously at the picture on the screen in front of him and replied casually: "The Sun-shooting Detector."

The Radiosolar probe is a probe launched by the Federation to the outer solar system last year. After many accelerations, its speed has reached 150 kilometers per second, 540,000 kilometers per hour, which is equivalent to two

One thousandth the speed of light.

The Federation's current carrier spacecraft that travels between Azure Star and Alien Star has a maximum speed of only 36,000 kilometers per hour. It takes two months to cross a distance of 50 million kilometers. The gap is not small.

As early as more than a hundred years ago, the Apollo 2 probe launched by Eagle Island could already fly at a speed of 240,000 kilometers per hour. At that time, Eagle Island was the fastest in the entire Federation.

A spacecraft can reach a speed of 38,400 kilometers per hour.

More than a hundred years have passed, and the speed of the detector has doubled, but the speed of the spacecraft has declined.

The reason is still the issue between quality and speed.

The greater the mass of an aircraft, the easier it is for its speed to reach the limit of human technology, or in other words, the limit of human physics knowledge.

Today's carrier-type spacecraft is much larger than the spacecraft that could only carry out moon landing missions at that time.

How to solve the problem between mass and speed is a key issue for the Federation to explore the universe.

"wrong."

Chen Mu denied Lao Liu's answer. He was also watching the battle scene on the screen. When he saw Ji Xinghe blocking the Imperial Armor, he relaxed completely. He was completely different from Lao Liu.

Old Liu also heard the relaxation in Shen Mu's tone. Thinking of Ji Xinghe's past achievements, the tension in his heart eased slightly.

"How could it be wrong?"

"It's really wrong." Shen Mu denied it again and answered: "It's a manhole cover."

"kindness?"

Old Liu frowned and recalled a certain rumor.

"Are you talking about the manhole cover that was blown away at the nuclear explosion test site? Let's not talk about the authenticity of this matter. Even if it is true, the theoretical speed of the manhole cover after being blown away by nuclear weapons is only seventy kilometers per hour.

Seconds, which is more than one and a half points different from that of the Solar System probe."

Rumor has it that during a nuclear explosion experiment in the last century, due to a calculation error by scientists, a manhole cover at the explosion site was blown away by the shock wave released by the nuclear weapon. Before being destroyed, it completely disappeared from the world that humans can detect.

among.

"It doesn't matter whether it's true or not. What's important is that in theory that manhole cover is possible."

As Chen Mu spoke, the light in his eyes became brighter and brighter, giving people a real feeling, looking very much like Ji Xinghe.

But what he received from Ji Xinghe's gift was only the Qi of the second stage. In theory, this should not happen, so it is worth studying.

It's just that no one can notice this yet. Lao Liu's attention is all on the screen, and Shen Mu himself doesn't notice it at all, and his tone is a little excited.

"Although the theoretical speed of that manhole cover is only 70 kilometers per second, don't forget that it has only experienced one acceleration. And how many times has the Xielu probe experienced acceleration? And our spacecraft, alone

Starships, how many times do they need to accelerate if they want to reach their top speed?"

"so what?"

"So, if multiple nuclear weapons can be used to accelerate that manhole cover, its theoretical speed can continue to increase. Seven hundred kilometers per second is possible."

"Awesome!"

Lao Liu suddenly shouted loudly. This praise was of course not because of what Chen Mu said, but because the battle on the screen was over.

After chasing for some time, the battle that finally started was so fast that many people were unable to react. They could only see Ji Xinghe locking the Prince Armor and punching it more than a dozen times before the Prince Armor disappeared again.

He couldn't move, even if he was stepped on by Ji Xinghe.

Chen Mu's eyes were also amazed, but not as big as Old Liu's reaction. He had already foreseen such a scene from the time when Ji Xinghe successfully stopped the Prince Armor.

However, because the battle did not end there, Shen Mu also fell silent for a short time.

It wasn't until Ji Xinghe dragged the Prince A away like a dead dog without encountering any pursuit or obstruction that he spoke again.

"I want to work on a propulsion engine that can produce an effect similar to a nuclear explosion."

Old Liu was stunned for a moment, his eyes turned to Chen Mu, and then he carefully thought about what he had just heard.

He was indeed a little careless just now, but now that he thinks about it, his eyes become weird.

"Are you crazy?"

"I'm not crazy."

"Theoretically, the manhole cover was indeed not directly destroyed, but that is because the manhole cover itself has no possibility of being destroyed. If it were a spaceship, no, even if it were an aircraft, the result of a nuclear explosion would be to be destroyed.

Destroy, or at least damage. Excuse me, what’s the point of using the propulsion engine that uses the power of nuclear explosions that you dream about in the daytime?”

"Nuclear blast engine? What a name."

Chen Mu sighed in admiration, and then said: "Yes, our aircraft, spaceships, etc. currently do not have the ability to directly withstand nuclear explosions. But the problem is that we now have the formula of tungsten steel alloy.

Energy shield technology, and I have never thought about using nuclear explosion engines on aircraft and spaceships in a short time. I want to use it on..."

Chen Mu moved his eyes away from Lao Liu's face and looked at the screen again.

There are three pictures displayed above. The one in the center is still the Emperor Armor dragging the Prince Armor, and on the left and right sides are the Star-Moon Armor and the Armor of God's Punishment, which are killing everyone.

Lao Liu was stunned for a moment, then turned his gaze to look at the screen again, then was stunned again, and finally his eyes returned to Shen Mu's face. He noticed Shen Mu's crazy and serious look, so he paused for a moment before speaking.

"You mean, Emperor A?"

"Strictly speaking, the mecha is made of tungsten steel, including the emperor armor, and it must be driven by an old man, because he is not afraid of the radiation produced by nuclear explosions. Well, Li Yuanba seems to be able to do it too."

In Lao Liu's mind, the scene he just saw emerged.

The Emperor Armor piloted by Ji Xinghe took advantage of the shock wave brought by the Imperial missile and gained an acceleration that could determine the outcome.

The power of that imperial missile is definitely incomparable to that of a nuclear explosion. If it is equipped with a tactical nuclear warhead...

Shen Mu's excited voice continued to sound while Lao Liu was thinking.

"Nuclear explosion engines can not only be used on battlefields on alien surfaces, but can also be used in space. There is no resistance in space, and nuclear explosion engines can theoretically accelerate the Emperor Armor countless times until the Emperor Armor or the Emperor Armor

The old man inside couldn't bear it.

The size and weight of the mecha are much smaller than that of the detection aircraft. Even if you use a mecha kit equipped with a propulsion engine, you can theoretically achieve a speed that is not weaker than that of the detection aircraft. I know that the Academy of Sciences is conducting relevant research

Experiment and find a faster way to send mechas from the blue star to the alien planet.

But the conventional propulsion engine is really not good. Although the maximum speed of the Sunshot probe can reach 150 kilometers per second, in theory, it only takes a hundred hours at the fastest to reach the alien planet from the Blue Star. But it can be so fast.

The speed is accelerated by the gravity of the Sui Star, and the Sui Star is not between the Azure Star and the Alien Star.

The nuclear explosion engine is different. It does not need to use the acceleration of the planet's gravity. It only needs to carry out nuclear explosions again and again to generate unprecedented propulsion. Even if it can only reach the maximum speed of the Sun-shooting probe..."

Chen Mu paused for a few seconds, looked at Old Liu's dumbfounded expression, and said: "The old man pilots Emperor A, and it only takes two hundred hours to travel between the Azure Star and the Alien Star. Note, it's a round trip. You know, this

Does it mean anything?"

Old Liu asked blankly: "What does it mean?"

Chen Mu took a deep breath.

"It means that if there are imperial space battleships that break through the blockade of our space fleet and go to the Blue Star, the old man can catch up with them, stop them, and kill them like he did today."

Old Liu finally understood and exclaimed: "Do you really want the old man to drive a mecha to kill the empire's space battleships?"

"I do not want."

When Chen Mu replied, he looked at the Emperor Armor driven by Ji Xinghe on the screen again.

"But if that day comes, the old man will definitely want to catch up. Whether he can destroy the empire's space battleship is his business. Whether he can catch up with the empire's space battleship is our business."

Lao Liu was silent for a while, and then spoke after a while.

"How?"

"You can't do it." Shen Mu suddenly laughed: "Although I know more than you, I can't do it alone. I have to find the Academy of Sciences."

Lao Liu, who was emotionally aroused, was suddenly poured cold water on Chen Mu. He was really offended and angry.

"Then you said nothing to me?"

"I have such a genius idea. Of course I have to tell others about it. It's a pity that you are the only one around me, and I don't know how to praise it."

"..."

"Hey, don't look at me like that. You are the first person to hear my genius idea. You will be written into history in the future. You should thank me."

"I thank you for eight generations of ancestors."

"hey-hey."

Shen Mu was not angry after being scolded. He opened the bracelet and began to formulate a more detailed design idea. However, the title of this design idea was not the nuclear explosion engine that he and Lao Liu just mentioned, but - the Imperial Engine.

This is normal. Among all the current mechas in the Federation, except for the emperor armor currently used by Ji Xinghe, there is really no one that can theoretically withstand the side effects of nuclear explosion engines.

Moreover, Chen Mu felt that the name Emperor Engine really matched Ji Xinghe.
