Chapter 249 One Million Hiroshima Atomic Bombs (3k)

During her conversation with Qian Mengjian, Luo Qing learned the following facts:

While the Solar System Fleet might not be able to destroy the Giant Ring with its military might, it certainly has the capability to destroy all of the Giant Ring's engines, and even to cleanse the entire surface of the Giant Ring, effectively wiping out the dinosaurs.

Driven to desperation, humanity accelerated 5000 star-class warships to 20% of the speed of light and rammed them into the giant ring.

This is equivalent to the total number of 5000 × 8000 = 40000000 star-shaped hydrogen bombs.

The energy of forty million stellar-type hydrogen bombs would create a crater even if the giant ring were a white dwarf, unless the ring itself were a neutron star.

Anyway, the Trisolaran fleet won't arrive on Earth for another 200 years. At worst, we can rebuild the number of star-class warships within those 200 years.

The Trisolaran civilization was left with only one planet and was very frugal with its resources, but humanity was not lacking in resources. The total amount of resources that the three Jovian planets provided to Earth was almost limitless.

But seeing Qian Mengjian's "I might as well explode with the dinosaur" expression, Luo Qing felt it was necessary to remind him.

Luo Qing said earnestly to Qian Mengjian, "Commander Qian, there's something I need to tell you. Shan Qing's sacrifice wasn't so simple. His death wasn't so simple. The main reason for his death was that he was attacked by the Dinosaur Empire's four-dimensional space warships."

Qian Mengjian was taken aback: "A four-dimensional spaceship? What is that?"

Luo Qing shook his head: "I'm sorry, I don't know either. Shan Qing was trapped in some kind of unknown space. When he was trapped in that space, my contact with Shan Qing was immediately lost. It wasn't until the very end that I was able to reconnect with Shan Qing through a mysterious bubble in that unknown space."

Ding Yi was the only person who witnessed this miraculous event through Luo Qing. He remained silent, frowning in thought.

Luo Qing continued, "At that time, Shan Qing had already suffered thousands of interdimensional attacks from the Devouring Empire, and was almost tortured to death. Later, in that unknown space, he encountered an attack from a four-dimensional spaceship. This warship was almost invincible, and all of Shan Qing's attack methods failed. Just when Shan Qing was about to be killed, Ding Yi reminded him to use the structure of four-dimensional space to attack, which finally destroyed that four-dimensional spaceship."

Qian Mengjian asked, "Could you explain in more detail?"

Luo Qing shook his head: "Shan Qing's remnant soul is still on the giant ring. After the fleet arrives near the Devouring Giant Ring, I will try to fly to the giant ring and retrieve his remnant soul. Before that, he will not be able to transmit any more information to me. However, you can ask Ding Yi; he seems to know a little."

Qian Mengjian turned his gaze back to Old Ding, who was standing to the side.

Ding Yi said quietly, "It's four-dimensional space."

Qian Mengjian asked, "I know that four-dimensional spacetime is three-dimensional space, and then adding one dimension of time makes four-dimensional spacetime."

Ding Yi shook his head: "Wrong. Four-dimensional space and Einstein's four-dimensional spacetime theory are not the same thing. Here, it refers to the pure spatial structure. Before Shan Qing's death, four-dimensional space was just a clear mathematical concept, referring to a space with four dimensions. In geometry, it can be compared to the definition of two-dimensional and three-dimensional space, and is described by the coordinate system x, y, z, w. It is mainly used to study the properties and topological structures of higher-dimensional geometric figures, and is the research object of branches such as linear algebra and differential geometry."

Qian Mengjian spoke succinctly: "Mr. Ding, I graduated from West Point Military Academy, and you know my level of physics... Please say something I can understand."

Ding Yi sighed, "In short, the four-dimensional space that only exists in the realm of mathematics has truly become a reality. Shan Qing has been trapped in a four-dimensional spatial structure, which has one more dimension than the three-dimensional universe. And that so-called four-dimensional space warship is a cosmic warship with a four-dimensional structure. Compared to four-dimensional space, three-dimensional space is just a shadow, just as a two-dimensional plane is just a shadow to us. This is why all of Shan Qing's attacks are ineffective against the four-dimensional space warship; no method in three-dimensional space can affect four-dimensional space. Just as no attack method of a shadow can threaten us."

Qian Mengjian asked, "Since the four-dimensional spaceship is so powerful, how did Shan Qing escape?"

Ding Yi: "At my prompting, he launched a hypercube attack that mimicked the structure of a four-dimensional space, destroying the four-dimensional warship, but he was also seriously injured. The four-dimensional warship was the main cause of his death."

Upon hearing this, Qian Mengjian became worried: "Doesn't that mean that these four-dimensional spaceships have an overwhelming advantage over the solar system fleet?"

Ding Yi shook his head: "You don't need to worry about that. Spaces with different dimensional structures cannot affect each other. Four-dimensional spaceships cannot appear in the three-dimensional universe. The reason it was able to hurt Shan Qing is because Shan Qing accidentally entered that small-scale four-dimensional space. We don't know how these four-dimensional spaces appeared, nor do we know what impact they will have on the upcoming war. In short, you must make the fleet be cautious and never underestimate the dinosaurs."

"To be honest, sending the expeditionary fleet directly into the Giant Ring before we understand that mysterious four-dimensional space is still somewhat risky," Ding Yi concluded.

Qian Mengjian is already preparing to leave again to convene a second operational meeting.

Luo Qing's voice caught up with Commander Qian, and he said, "Commander Qian, rest assured, in the subsequent battles, I will do my best to minimize the casualties of the human warships."

Qian Mengjian's hand was already on the hatch button. He turned his head and said, "Don't take any risks, and don't leave the fleet to fight alone. Shan Qing's sacrifice is already enough to make human civilization grieve. The Wallfacers must not be allowed to suffer any more accidents."

Unexpectedly, Luo Qing said very cautiously, "I won't be so reckless. If the clone dies, so be it. It's just a clone. I know nothing about four-dimensional space. Normally, spatial laws can only be used by the highest-level cultivators in our world, which worries me. I won't act rashly until I understand four-dimensional space. You can rest assured about that."

"Although human civilization has developed very well now, I still hope that I can live a little longer."

"After all, the Trisolaran fleet is still waiting behind."

… 20 days later.

The large ring detected the approach of a large number of small, high-speed targets, which had a speed of approximately 0.13c.

This familiar speed immediately alerted the Devouring Civilization.

It is currently known that the herbivorous dragon representatives sent by the Devouring Civilization have reached a ceasefire agreement with the Light Speaker Civilization, the White Fish Clan, and the Balloon Fish Civilization.

The Great Ring Commander, acting as the temporary leader of the Devouring Civilization, personally signed a peace treaty with the Light Speaker Civilization. The Devouring Civilization acknowledged the Light Speaker Civilization's status as a breeding civilization, but simultaneously informed the glowing mushrooms that, as beings of the Great Ring, all civilizations within it were inextricably linked to the Great Ring's fate. The Devourers would cede the Sixth District to these breeding civilizations, but warned the mushrooms against further disturbances.

Otherwise, even under the explosion of the nuclear mushroom, the Devourer would completely annihilate the mushroom population.

It should be noted that the volume of each district in the Great Ring is no less than that of the Earth, and the surface area of ​​District 6 in the inner ring is comparable to that of the Pacific Ocean. Such a vast living area was completely given to the Light Speaker civilization, which won unanimous praise from the Puji.

Stop causing trouble and just be a normal person.

After the initial disaster relief efforts, the commander of the Great Ring ordered the activation of the Great Ring's automatic repair system to begin repairing the Great Ring's engine, which had not been completely destroyed but had only been damaged.

The giant ring engine is the most important component of the giant ring and must be repaired as soon as possible.

After barely managing to resolve the internal issues, the Commander of the Great Ring was finally forced to face a new round of attacks from the human fleet.

Humans really never stop.

The number of small, high-speed targets detected so far is alarming. There are approximately one million high-speed targets flying at 13% speed.

Upon learning of the quantity of 100 million, the Commander of the Great Ring was greatly alarmed.

This number of stellar nuclear bombs could indeed severely damage the Giant Ring and wipe out all life on its surface.

But after further testing, it was relieved to find that these high-speed targets were not as large as the star-shaped nuclear bomb, with a diameter of about 0.3 meters, and were spherical in shape, weighing one ton.

This appears to be a high-kinetic-energy metal projectile.

Soon, the weapons research department of the Devouring Civilization analyzed what kind of weapon it was: electromagnetic gun technology unique to humankind.

The technology for millions of electromagnetic railguns was developed by 488 star-class warships bombarding the area at 10% of the speed of light for a full day and night.

The electromagnetic railgun's muzzle velocity is 3% of the speed of light. Adding the warship's cruising speed of 10% of the speed of light, the total is 13% of the speed of light. Without any interception or defense, these more than one million electromagnetic railgun shells will rain down on the surface of the large ring like divine punishment.

If the railgun were fired from a stationary human warship, the sheer size of the giant ring would easily withstand it. While a projectile traveling at 3% of the speed of light would be powerful, its limited size limits its effectiveness; it might be able to harass and devour a fleet, but it wouldn't pose a significant threat to the giant ring.

However, this 10% increase in velocity brought these metal projectiles to a terrifying speed of nearly 13%. According to the theory of relative kinetic energy, the kinetic energy of each metal projectile was no less than that of a 10-ton nuclear explosion.

To use a historical analogy, this is equivalent to 100 million Hiroshima atomic bombs.

Of course, even a million Hiroshima atomic bombs would not threaten the structure of the Great Ring, but the industrial areas and space docks on the surface of the Great Ring would not be able to withstand such an attack.

Upon learning that a million electromagnetic kinetic energy cannons were approaching, the commander of the Great Ring issued only one order:
[Increase the concentration of atmospheric particles in the outer ring]

The surface of the large ring is also covered with an atmosphere, which is about one-third the concentration of the inner ring. The presence of the atmosphere can wear down metal projectiles to the greatest extent. If the density of the existing atmosphere is increased to three times, it will be enough to wear down these metal projectiles without damage.

Is this the first probing attack by the human fleet?

It is really strong.

But the Big Ring is not an easy target; it's time to fight back.

The commander of the Great Ring issued the second order:
[Adjust the gravitational lens to focus energy into 350 super gamma laser beam cannons, executing a long-range laser counterattack against the incoming electromagnetic projectiles!]
