Rebirth of the Super Battleship

After sending out the message, Xiao Yu began his quiet wait.

Superluminal communication primarily relies on the quantum entanglement effect. Quantum entanglement refers to the phenomenon where two particles in an entangled state will instantly influence each other, regardless of the distance between them. While the exact principles of quantum entanglement remain unknown to humanity, it doesn’t hinder Xiao Yu from utilizing this concept.

However, quantum entanglement alone cannot be directly used for communication. While the information transfer between entangled particles is instantaneous, observers cannot discern the meaning of the transmitted information through the parameters of just one particle. Only by combining the parameters of both particles can the information be accurately decoded.

This limitation, however, brings the problem back to square one: the parameters of the other particle must still be transmitted to the observer through conventional methods, which negates the concept of faster-than-light communication.

Xiao Yu found a clever way to circumvent this obstacle. By using a large number of entangled particles and applying a specific logical algorithm, he could manipulate the parameters of these particles to follow a discernible pattern. The receiving end could then use the algorithm to reconstruct the transmitted information.

Nevertheless, this method has a drawback: during the process of quantum communication, there is a probabilistic error. With Xiao Yu’s current abilities, he can ensure that the information received at the other end is 99.99% similar to the original message, leaving a 0.01% margin for error. This margin is an inherent flaw of the logical algorithm and can only be minimized through various means but never completely eliminated.

Now, it was time to test whether Xiao Yu’s approach was viable.

Seventy seconds and 0.2 milliseconds later, Xiao Yu received the reply.

“Hello, universe. My name is Xiao Yu. I come from Earth.”

Next, Xiao Yu immersed himself in further research on quantum communication.

The advantages of quantum communication were evident. The most significant was its real-time nature. Another was the security of the transmitted information.

Quantum communication does not rely on electromagnetic waves for transmission but instead uses a process Xiao Yu did not yet understand. This means that no matter how strong the interference between the communicating parties, it would not affect the transmitted information.

This advantage solved one of Xiao Yu’s greatest concerns. Previously, he had worried that if an alien civilization discovered that he was an electronic lifeform rather than a sentient civilization, they might use interference methods to strip him of control over his ships. But with quantum communication, Xiao Yu no longer feared any interference.

However, this advantage was also a disadvantage. Since quantum communication does not use radio waves, Xiao Yu couldn’t use it to transfer himself. To achieve self-transfer, conventional radio waves were still necessary.

After numerous experiments and improvements, Xiao Yu created the “Superluminal Type-1” quantum communication device. This model could provide real-time communication with an error rate below one in ten million within a range of 200 million kilometers.

Beyond the 200-million-kilometer range, the accuracy of quantum communication would drop exponentially, and the information would rapidly degrade into unreadable gibberish.

But even real-time communication within 200 million kilometers was incredibly useful for Xiao Yu. Moreover, he could extend this range indefinitely by constructing relay stations.

With the Superluminal Type-1 communication device, the construction progress of Xiao Yu’s Tianyuan IV star system made another leap forward. Xiao Yu deployed tens of thousands of communication devices throughout the Tianyuan IV system, effectively achieving full signal coverage. As long as Xiao Yu remained in the Tianyuan IV star system, he could contact any instrument in the system at any time and place.

Stationed in Tianyuan A’s orbit, Xiao Yu remotely directed the construction of interstellar fortresses at Tianyuan C and Tianyuan B. As for Tianyuan A’s headquarters, it had already become heavily fortified. The entire planet was now covered with hundreds of large interstellar shipyards, thousands of satellites, tens of thousands of spaceships, and tens of thousands of space gun turrets. It had truly become an impenetrable fortress.

At Tianyuan C and Tianyuan B, Xiao Yu installed ten colossal energy cannons. These energy cannons had a range of ten million kilometers and could destroy an asteroid with a diameter of twenty kilometers in a single shot. In the past, such destructive power was unimaginable. Even the largest hydrogen bomb that Xiao Yu could currently produce could only shatter such an asteroid, not obliterate it completely.

Due to their immense size, these energy cannons could only be constructed on the satellites of Tianyuan B and Tianyuan C; none of Xiao Yu’s current spaceships could accommodate these behemoths.

In addition to the ten colossal energy cannons, Xiao Yu also stationed more than ten thousand Village-Class and Town-Class spaceships, along with one hundred 300,000-ton County-Class spaceships at these locations. Furthermore, Xiao Yu buried a large number of controlled mines and concealed turrets in the asteroid belt. These mines and turrets were designed to remain harmless to his own ships while delivering devastating blows to any enemy under Xiao Yu’s control.

The entire Tianyuan IV star system was now fortified into an inescapable web. Xiao Yu was confident that if an enemy with technological parity to the Moluton Civilization dared to invade, he could obliterate them into debris within one hundred seconds.

By this point, Xiao Yu had been in the Tianyuan IV star system for over two hundred years. During this time, Xiao Yu had truly experienced what paradise felt like. Indeed, this place was a paradise.

With infinite resources and precious peace, what could be better than this?

The large particle collider encircling Tianyuan IV continuously conducted experiments, generating massive amounts of data. On the surface of Tianyuan A and in space, Xiao Yu’s laboratories were everywhere, working on dozens of major research fields and more than three thousand projects.

Xiao Yu’s technological development flourished like never before.

The most notable breakthrough was in materials science, which finally overcame its limitations. This led to the construction of the first combat-ready City-Class spaceship.

This City-Class spaceship had a mass of four million tons when unloaded and was equipped with twenty energy cannons. Each cannon possessed 60% of the power of the ground-based cannons at the interstellar fortresses of Tianyuan B and Tianyuan C. According to Xiao Yu’s war simulations, a fleet of five City-Class spaceships, accompanied by 800 County-Class spaceships and 10,000 Village-Class and Town-Class spaceships, could completely destroy an interstellar fortress.

This was a true war fortress! In fact, just two City-Class spaceships alone, without any escort ships, could annihilate the entire Moluton Civilization.

During this period, Xiao Yu also made significant advancements in computer technology. The newly constructed super photon computer was a hundred times faster than the computers Xiao Yu had before arriving at Tianyuan IV. This new computer was installed in the City-Class spaceship, which became Xiao Yu’s new flagship.

Xiao Yu gave this City-Class spaceship a name filled with nostalgia for his homeland.

“Since it’s a City-Class spaceship… let’s call it Beijing,” Xiao Yu thought. “Unfortunately, the material requirements for City-Class spaceships are so demanding that my current ability to produce such ultra-high-strength materials is still very limited. Moreover, there won’t be any major breakthroughs in the foreseeable future. By calculation, building one City-Class spaceship takes thirty years. Well, no need to rush; I have plenty of time.”

With this thought, Xiao Yu once again immersed himself in an era of massive construction.

A hundred years quietly passed. Including the Beijing, Xiao Yu had constructed four City-Class spaceships in total, naming them the Beijing, Shanghai, Tianjin, and Chongqing. In addition to these four City-Class spaceships, Xiao Yu built hundreds of County-Class spaceships, thousands of Town-Class spaceships, and tens of thousands of Village-Class spaceships.

All these ships were equipped with nanorobot repair technology, and every County-Class spaceship and above was armed with energy cannons.

Activating this fleet of over ten thousand spaceships would consume 70% of Xiao Yu’s computational capacity. Combined with the demands from support ships, ground bases, space turrets, controlled mines, and concealed turrets, Xiao Yu’s computational power would be completely maxed out. However, Xiao Yu could only smile wryly at this reality.

He realized that the pace of his computer technology development seemed to be lagging behind the expansion of his fleet.

“This isn’t a good sign,” Xiao Yu thought. “I need to accelerate the development of computer technology. Until breakthroughs are made in computing, I’ll have to temporarily halt the construction of warships.”

With this resolution, Xiao Yu focused entirely on advancing his technology.

Just as Xiao Yu was engrossed in his research, a sudden distortion appeared 2 billion kilometers away from Tianyuan IV in the dark expanse of space. A pure white, streamlined object resembling a drop of water emerged from the void.

It seemed alive as it silently observed Xiao Yu’s activities. A month later, it transmitted a message to Xiao Yu.

“Greetings, stranger of the mechanical civilization.”
