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

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

Lao Liu looked at the screen in front of him a little nervously, and replied casually: "The Sun Shooting Probe." ”

The Sunshot probe, a probe launched by the Federation outside the solar system last year, has reached a speed of 150 kilometers per second and 540,000 kilometers per hour, equivalent to 1/2000 of the speed of light after many accelerations.

The Federation's current carrier-type spacecraft between Azure Star and Alien Star has a maximum speed of only 36,000 kilometers per hour, and it takes two months to cross a distance of 50 million kilometers.

As early as more than 100 years ago, the Apollo 2 probe launched by Eagle Island was able to fly at a speed of 240,000 kilometers per hour, and at that time, Eagle Island, the fastest spacecraft in the Federation at that time, could reach a speed of 38,400 kilometers per hour.

More than 100 years have passed, and the speed of the probe has doubled, while the speed of the spacecraft has decreased.

The reason for this is the problem between quality and speed.

The more massive the aircraft, the easier it is for the speed to reach the limits of human technology, or in other words, the limits of human physical knowledge.

Today's carrier-type spacecraft are much larger than those of spaceships that could only carry out missions to the moon at the time.

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

"That's not right."

Shen Mu denied Lao Liu's answer, he was also looking at the battle screen on the screen, and when he saw Ji Xinghe blocking in front of the emperor armor, he completely relaxed, completely different from Lao Liu.

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

"How could it be wrong?"

"It's really not right." Shen Mu replied after denying it again: "It's a manhole cover." ”

"Huh?"

Lao Liu frowned, recalling a certain rumor.

"You're talking about the manhole cover that was blown away at the nuclear explosion test site? Let's not mention that there is a problem with the authenticity of this matter, even if it is true, after the manhole cover was blown away by nuclear weapons, the theoretical speed was only 70 kilometers per second, which was more than a little bit worse than the Sunshot probe. ”

It is rumored that in a nuclear explosion experiment in the last century, due to the error of calculation by scientists, a manhole cover at the explosion site was blown away by the shock wave released by nuclear weapons, and completely disappeared into the world that human beings can detect before it was destroyed.

"It doesn't matter if it's true or not, the important thing is that in theory, that manhole cover is possible."

When Shen Mu spoke, the light in his eyes became brighter and brighter, and it actually gave people a sense of substance, looking very much like Ji Xinghe.

But what he got from Ji Xinghe's gift was only the qi of the second realm, and theoretically this situation should not occur, so it is worth studying.

It's just that no one can find out about this at present, Lao Liu's attention is all on the screen, and Shen Mu himself is completely unaware, and his tone is a little excited.

"Although the theoretical speed of that manhole cover is only 70 kilometers per second, you must not forget that it only went through one acceleration. And how many times did the Sunshot probe accelerate? And our spaceships, individual starships, how many times do they need to accelerate to reach their top speed? ”

"So what?"

"Therefore, if you can use multiple nuclear weapons to accelerate that manhole cover, its theoretical speed can continue to increase, and 700 kilometers per second is possible."

"Awesome!"

Lao Liu suddenly shouted, this admiration was of course not because of Shen Mu's statement, but because the battle on the screen was over.

This pursuit lasted for some time, and the battle finally began, so fast that many people couldn't react, and they could only see that after Ji Xinghe locked the prince armor, he smashed more than a dozen punches, and the prince armor could no longer move, even if it was trampled under the feet of Ji Xinghe.

Shen Mu's eyes were equally amazed, but he didn't have Lao Liu's reaction as big, he had already foreseen such a picture from the time 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 armor 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 that of a nuclear explosion."

Lao Liu was stunned for a moment, his gaze turned to Shen Mu, and then carefully recalled what he had just heard.

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

"Are you crazy?"

"I'm not crazy."

"In theory, the manhole cover was not directly destroyed, but that was because the manhole cover itself did not have the possibility of destroying it or not. If it is a spaceship, no, even if it is replaced by an aircraft, the end of a nuclear explosion will inevitably be destroyed, or at least destroyed. Excuse me, do you daytime dream of this ...... What's the point of using a propulsion engine with the power of a nuclear explosion? ”

"A nuclear engine? Good name. ”

Shen Mu sighed, and then said, "Yes, our aircraft, spaceships, etc., currently do not have the defense capability to directly withstand a nuclear explosion. But the problem is that we now have tungsten alloy formulas, we have energy shield technology, and I haven't thought about using nuclear explosion engines in aircraft and spaceships in a short period of time. I want to use it for ......"

Shen Mu's gaze moved away from Lao Liu's face and looked at the screen again.

There are three pictures shown above, and in the center is still the Emperor Armor dragging the Prince Armor, and on the left and right sides are the Xingyue Armor and the Divine Punishment Armor that are killing all directions.

Lao Liu was stunned, turned his gaze to look at the screen again, and then was stunned again, and finally turned his gaze back to Shen Mu's face, and noticed Shen Mu's crazy and serious appearance, but he was still stunned before speaking.

"You mean, Emperor Armor?"

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

In Lao Liu's mind, a scene he had just seen appeared.

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

The power of that Imperial missile is certainly not comparable to a nuclear explosion, if it is equipped with a tactical nuclear warhead......

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

"The nuclear explosion engine can be used not only on the battlefield of the alien surface, but also in space. There is no resistance in space, and the nuclear explosion engine can theoretically accelerate the Emperor Armor countless times until the Emperor A or the old man in the Emperor Armor cannot bear it.

The size and weight of the mecha are much smaller than those of the probe vehicle, and even if the mecha kit equipped with the propulsion engine is used, it can theoretically achieve a speed that is not weaker than that of the probe vehicle. I know that the Academy of Sciences is conducting experiments to find a faster way to get the mechs from Azure to Alien.

Although the maximum speed of the Solar Probe can reach 150 kilometers per second, it will theoretically only take 100 hours to reach another star from Azure Star. But it can have such a fast speed because it takes advantage of the acceleration of the gravitational pull of the year-old star, and the year-old 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 perform nuclear explosions again and again, and it can produce unprecedented propulsion. Even if it can only reach the maximum speed of the Sunshot probe......"

Shen Mu paused for a few seconds, looked at Lao Liu's stunned expression, and said, "The old man's driver Emperor Armor only needs two hundred hours to be able to travel back and forth between the Azure Star and the Alien Star. Attention, it's round trip, you know, what that means? ”

Lao Liu was stunned and asked, "What does it mean?" ”

Shen Mu took a deep breath.

"It means that if the Empire's space warships break through the blockade of our space fleet and go to the Azure Star, the old man will be able to catch up with them, stop them, and kill them like he did today."

Lao Liu finally understood, and exclaimed, "Do you really want the old man to drive a mecha to cut down the empire's space battleship?" ”

"I don't want to."

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

"But if there really is a day, the old man will definitely want to catch up. Whether he can cut down the Empire's space warships or not is his business. Whether he can catch up with the Empire's space warships or not is our business. ”

Lao Liu was silent and 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 mobilized, was suddenly splashed with cold water by Shen Mu, and he was really offended and angry.

"So you're talking to me?"

"Lao Tzu has such a genius idea, of course I have to tell someone, but it's a pity, there is only you around, and you don't know how to praise it."

“……”

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

"I thank you for your eight ancestors."

"Hey, hey."

Shen Mu, who was scolded, was not angry, opened the bracelet and began to formulate more detailed design ideas, but the title of this design idea was not the nuclear explosion engine that Lao Liu just said, but the emperor engine.

This is also normal, among all the current mecha in the Federation, except for the Emperor Armor that Ji Xinghe is currently using, there is really no one that can theoretically withstand the side effects of the nuclear explosion engine.

Moreover, Shen Mu felt that the name Emperor Engine was really compatible with Ji Xinghe.

…………

Mountain of the Gods, Imperial Command.

The expression of the King of the Imperial Zhenbei did not change significantly from beginning to end, just like a Wuliushang who died on the battlefield, not his son.

But the imperial crown prince knew very well that King Zhenbei's emotions were not as calm as it appeared, and the changes in the surrounding air pressure revealed that King Zhenbei was no longer able to control the qi in his body.

This is unusual.

According to the nine-stage realm divided by Ji Xinghe, the king of Zhenbei has reached the level of the seventh stage realm, and it is a very top-notch one.

Because he has obtained the power of inheritance, Ai Dakang, who has been promoted to the seventh stage realm, cannot compete with the king of Zhenbei at this stage.

"Although it is not appropriate to say this, ......" the prince hesitated in his tone: "Wu Liushang's death has nothing to do with my command. ”

King Zhenbei didn't react, his eyes looked straight at the picture on the screen, focusing on the prince armor who was dragged by the emperor armor, as if waiting for a miracle to come.

However, until the Emperor Armor, the Star Moon Armor, and the Divine Punishment Armor completed the convergence to a certain extent, that is, there were no more Imperial forces that could stop the three mechas.

The Prince's Armor, piloted by its most powerful son, did not struggle in any way.

It's really dead.

In fact, the life support system in Prince Jia's family had already sent back a report of Wu Liushang's death.

The waiting of the king of Zhenbei is really a little redundant.

There was some silence in the command center, and the soldiers and staff who kept giving orders all lowered their voices.

The crown prince, who was not afraid of offending the king of Zhenbei, and was even very willing to offend the king of Zhenbei, was still a little flustered.

It asked, "Or, throw a nuclear weapon?" ”

King Zhenbei did not respond.

The crown prince continued: "Although Ji Xinghe is definitely not afraid of nuclear weapons, Xingyue Jia can also bring him good protection, not to mention Emperor Jia. But if we're targeting the Divine Punishment Armor, there's a good chance we'll kill that human mecha warrior.

Or, throw it directly at the federal position, we will find a suitable opportunity, and it should not be a big problem to kill tens of thousands of people. At last...... gave Wu Liushang a funeral. ”

King Zhenbei finally reacted, and he turned his head to look at the crown prince.

"That's what you and your father want?"

The prince frowned: "I said it, this has nothing to do with my command. ”

"But you said that it is impossible for Li Yuanba to participate in the war."

"Yes, it is absolutely impossible for Li Yuanba to participate in the war, and in the Imperial Jiali, it is definitely not Li Yuanba."

"And how did he kill my son?" King Zhenbei was-for-tat, and even stepped forward to approach the prince, making all the orangutan monkeys in the headquarters nervous.

"You think, it's anger?"

The crown prince did not have the slightest fear, staring into the eyes of King Zhenbei.

"Although theoretically, the pilot of the Emperor Armor can kill the Wuliu Shang so quickly, the most likely thing is to use the power of Qi to penetrate the defense of the mecha. But even Ji Xinghe doesn't have such a strong qi, if he had, he wouldn't have been beaten so badly by Ai Dakang before. ”

Ai Da Kang lost, but in the mouth of the prince, it sounded like Ai Da Kang had won.

But if you really want to talk about it, Ji Xinghe was indeed beaten a little badly at that time.

King Zhenbei was silent.

Wu Liushang only said two words in the end - you are.

At that time, it subconsciously thought that what Wuliu Shang wanted to talk about was Ji Xinghe, because only Ji Xinghe in the whole federation had the qi that was not weaker than Wu Liushang.

But the driver in the Xingyue Armor is most likely Ji Xinghe, thinking that the prince said that Li Yuanba is unlikely to participate in the war in the near future, it thinks that Li Yuanba should have the same ability as Ji Xinghe, that is, Li Yuanba's qi may not be weaker than Ji Xinghe.

But after the anger subsided a bit, it felt that the possibility of Li Yuanba in the emperor armor was too small.

Moreover, even Ji Xinghe is unlikely to be able to do this.

"Then my son." King Zhenbei looked at the crown prince and asked, "How did you die?" ”

"I don't know for the time being, because we can't get the mecha of the Wuliu Shang." The prince replied: "However, I will find a way to know, you know, I have a way." ”

King Zhenbei took a deep breath.

"You'd better find out soon."

This is already an obvious threat, but because the orangutan who said this is the king of Zhenbei, the prince has nothing to do, but he has to be obedient and know the truth in some way as much as possible.

The four kings of the empire, the king of Zhenxi, have clearly joined the rebels, and the current actions of the king of Zhennan are also somewhat obvious.

If this brings the King of Zhenbei to the side of the rebels, its father, Emperor Wu III, will probably find some trouble, let alone it?

"Of course. But ......" the prince groaned slightly, and said, "I think we should talk about how to avenge Wuliushang now." ”

King Zhenbei's oppressive gaze finally moved away from the prince and looked at the big screen again.

Its son, Wu Liushang, had been dragged far away by Ji Xinghe, so far away that it would never be possible to bring it back.

But this revenge can be avenged.

"I know you have twelve duke armors under your command, let them go into battle, and also, the anti-galaxy legion."

King Zhenbei made another request.

"Yes." After the prince agreed, he asked, "What about you?" ”

King Zhenbei was silent for a moment.

When it received the order to come to the alien battlefield, it already knew what its nephew who was the emperor meant.

It was also ready to lose some of its own strength for this war, but before today, it could never have imagined that its losses would be so large.

Wu Liushang was its most powerful son, and the most gifted son, and in the imperial family of the Empire, this talent meant that something was possible.

Now, however, there is none.

It says.

"As long as you tell me who killed my son, I will take revenge."
