Girls und War

As he spoke, he waved the command panel in front of him and issued the initial fleet orders.

There is also such a command panel in front of Xia Shu, which lists the fleet strength and turn count.

The scale of the combat star field on the primary chessboard is roughly limited to a distance of one hundred light years.

And generally, the rules of space folding and wormholes do not apply. So it is relatively simple to understand.

Although it sounds simple, when the chessboard is extended, the huge three-dimensional virtual interface is enough to make people dizzy.

Not to mention, we have to constantly calculate the gravitational influence that the stars in space exert on each other, as well as the various constants that change subtly as a result.

In fact, unlike the virtual universe pictures in popular science books, the real universe is actually quite empty.

The distance between one star system and another may be several light years away.

If you want to reach different places through space travel, you have to face a very physical problem.

The speed of light is limited.

According to the theory of relativity, an object with mass cannot travel faster than light.

If you want to fly faster than the speed of light, you will face a barrier in space, which is a physical barrier that squeezes all matter. Any attempt to break the speed of light will cause the attempter to crash into the wall and be shattered.

But is this barrier truly insurmountable? Does this mean humanity can only navigate the universe at a snail's pace, measured in years?

Obviously not.

In order to successfully complete intergalactic travel without affecting physics, humans have developed another theory.

That's warp speed sailing.

The so-called curvature originally refers to the bending value of a curve at a certain point.

Here we are referring to the curvature of space, which is a method of changing the rules of physics to shorten the distance and allow the destination to "run ahead" on its own.

However, this behavior of changing the physical rules cannot be reversed within a period of time.

It's like digging a trench in the ground and then filling it back in without leaving any trace.

This is the "trail" left by curvature navigation.

This trail will appear very clear under the illumination of starlight, just like a firefly shining in the night.

In a sandbox battle, this is like a glowing golden line suddenly appearing in the dark curtain of the universe, which is particularly eye-catching.

Therefore, the tactic of the battle is to find out all the enemy's combat forces bit by bit based on the track left by the curvature navigation, and eliminate them completely without leaving a single one.

However, although the trajectory of curvature navigation is very clear, their combat map is still extremely large.

Finding the track of a spaceship in a map that is hundreds of thousands of light years away is as difficult as finding a strand of hair in the Pacific Ocean.

Because the universe is really that big.

In the sandbox, the scope of their exploration each round was also limited. Each round of exploration was like casting a thin net in the ocean.

Think about it, the speed of light is only 300,000 kilometers per second. A spacecraft can travel faster than the speed of light. By the time you capture the trajectory of a curvature-traveled ship, the enemy would have already vanished. Would they still be waiting there for you to take them down?

Therefore, the attack in the sandbox battle basically relies on prediction.

Let us introduce another concept.

That is, the attack power of space combat weapons is surprisingly great, and it is a range attack.

You can imagine it as a flashlight shining somewhere, and everything within the area of ​​the light is completely destroyed.

The main gun of a space battleship has an attack range of about fifteen light years and an attack range of about 2°.

Therefore, the main warships in sandbox battles basically will not act in groups.

It can be understood as one battleship for one formation, and each formation is wandering around the battlefield, constantly looking for the shadow of the enemy fleet and then annihilating it.

In the basic space warfare course, the students control a total of ten chess pieces, that is, battleships.

Each battleship can only move ten light years in a unit of time, and the fleet's main guns require a unit of time to recharge.

The condition for victory is to annihilate all the enemy's troops.

If you fail to completely annihilate the enemy within the specified time unit, it will be considered a draw no matter how many battleships you destroy.

Of course, there are also rules for super long tug-of-war with unlimited rounds.

However, the "senior" just wanted to give Xia Shu some guidance, so they still played according to the professional competition's fifty-round rules.

At the same time, in professional rules, both sides' turns are carried out simultaneously.

That is, in each round, they can input their own combat strategies into the panel.

Then, after a unit of time passes, the battle situation is played out on the sand table, and both sides proceed to the next round of actions.

The game continues until one player loses or the round ends and the match is a draw.

There are many other details about the rules, which are explained in detail in the subject of space warfare.

Although Xia Shu still hasn't fully understood it, it doesn't prevent her from being tortured and killed by her "senior".

So not long after the game started, by the fifth round, the "senior" had already caught the clues of Xia Shu's fleet and killed one of the chess pieces with a round of concentrated fire.

Following a burst of supernova explosion special effects, Xia Shu's expression immediately became uncomfortable.

944. Lan Ke Senior's Guidance

During the sandbox battle, both players issue turn commands synchronously.

So there is no difference between first and second.

Then the only reason for being at a disadvantage is that you are not as skilled as others.

There is nothing else.

Searching for enemies on the chessboard, predicting and attacking were simple operations, but Xia Shu just couldn't figure it out, while the opponent could easily predict the movement of the chess pieces.

In the sandbox battle rules, the unit time for each round of chess pieces' actions is the time it takes for the main ship to recharge. Therefore, the operations of a round are limited to this time.

Of course, in actual combat, it may not be that simple.

For example, while the main gun is charging, other reconnaissance ships discover new targets and spread the news using quantum communication.

But for strategic deduction, simple rules are enough.

Moreover, there are actually many automated attackers and defenders in the chess rules.

For example, when playing chess, if the chess pieces of the enemy and our side happen to be in the detection range of each other, they will automatically attack the other side when the main gun is fully charged.

This is called "Exchange" in the rules.

There is also another particularly interesting setting.

That is the main gun of a chess piece. When it is not charging, it will automatically fire when a clear enemy appears within the attack range.

This will lead to a very interesting phenomenon.

That is, your predicted attack happened to miss the enemy. At this time, the enemy discovered your attack and you are within its attack range.

The chess piece will automatically counterattack.

Commonly known as "rebound".

Because the chess pieces have a certain advantage when these charges are not released, novices like Xia Shu and others have the habit of attacking from behind.

But no matter what, the chess piece's reconnaissance range is much smaller than its attack range.

Therefore, this habit of tending to be safe can easily lead to disadvantages in chess battles.

However, it is also not advisable to just mindlessly shoot at the map without any regard.

Because this type of range attack will cause a strong fusion reaction in all matter within the attack range.

Therefore, when attacking, it is actually very easy to expose one's own coordinates.

If at that time, he happened to be within the enemy's attack range and the enemy's main gun had just been fully charged, then even if the attack was successful, he would still be "eaten" by other chess pieces.

Therefore, in high-end chess games, it is very easy for either no cannons are fired, or once fired, a chain reaction of exchanging pieces will occur.

It is very likely that both sides had ten chess pieces in the previous round, but in the next round, it has become a endgame with only one or two chess pieces.

Of course, with Xia Shu's level, it is impossible for him to fight with his "predecessors" to the endgame.

And although the "senior" took the initiative and captured one of her pieces, because all of Xia Shu's pieces were ready to go, her automatic counterattack immediately exchanged for two of the opponent's pieces.

Xia Shu seemed to have the advantage on the scene.

However, Xia Shu was very clear that the situation was already unfavorable to him.

Because of this automatic counterattack, several chess pieces that were hidden very deeply were exposed.

Soon, after a few rounds, the "senior" completed the roll call of Xia Shu's chess pieces one by one.

Although in the end Xia Shu cleverly destroyed two stars and created a dark area for himself to hide.

But it was obviously impossible for the "senior" to let Xia Shu drag the game to a draw.

She quickly calculated Xia Shu's final hiding place by observing the curvature trajectory of the chess piece that was finally exposed when the star exploded.

So a few rounds of volleys ended the game in the 23rd round.

Xia Shu accepted the defeat with conviction, but he did not feel bad. Instead, he felt that the game was very enjoyable.

She thought that the professional chess player would crush her without any chance of fighting back.

Now it seems that I still had a chance of winning.

But if you think about it carefully, this should be because the "senior" didn't want to play too hard, so he deliberately gave up a few moves, which can be regarded as a "guiding chess game" for the children.

This way, they won't completely lose interest in the space battle sandbox battles.

-

After seeing Xia Shu finish, Qingxian and You didn't see the trick. Instead, they thought, "That's it? I can do it too." So they became eager to try.

Seeing this, the "senior" played a round with them one by one.

Needless to say, the result was that they were easily defeated head-on.

However, after this back and forth, the three of them seemed to have experienced the joy of playing chess.

Once you accept the various rules of sandbox combat, it seems that this chess... is quite interesting.

"Well, okay, I think I have a clear idea of ​​your level."

After finishing the game of chess, the "senior" closed the holographic panel and drank his coffee calmly.

The three of them looked at each other, confused for a moment. What on earth was this "senior" who hadn't even introduced his own name trying to express?

So they winked at each other, and finally Xia Shu took the lead and asked, "Then, Senior, how should we learn space warfare?"

The "senpai" looked at Xia Shu and said, a little puzzled, "Playing chess. Isn't that what you came here to ask? I told you."

"Ah? This... playing chess can improve our grades?" Qingxian was a little bit incredulous. She still felt that sandbox battles were just a game, and didn't seem to be of any help in memorizing formulas.

Seeing this, the "senior" said impatiently, "Sandbox chess is a strategic game based on the real universe. It's about both education and entertainment, don't you understand? Many of the rules on the chessboard are actually microcosms of constant formulas. By the time you're familiar with the discipline of space warfare, even without the chessboard assist, you'll be able to calculate fleet flight trajectories smoothly—that's when you'll be considered a master."

After hearing this, the three of them showed an expression of enlightenment.

The "senior" yawned again and seemed to be sleepy again.

The three were about to say goodbye and leave when they heard footsteps at the door. A researcher suddenly led Professor Hua in.

"Ah, Senior Sister, you're still here." The researcher seemed very surprised by the presence of the "senior" and said, "You've been here for three days, right? Go back to sleep. I'm serious."

Hearing this, the "senior" curled his lips and said, "No. I still have to play chess."

Then he turned to look at the professor and said, "Long time no see, teacher. You brought your students here for a tour today."

"Ah, yes." The professor nodded, then smiled at Xia Shu and the other two and said, "You're here too? Have you seen Lan Ke? Then I don't need to introduce you."

Then the three of them suddenly realized that the name of this "senior" was Lan Ke.

It's quite appropriate.

However, when Xia Shu heard this name, he showed a puzzled expression again.

This name sounds familiar, I seem to have heard it somewhere before?

The young commander seemed to have mentioned this name.
