In the dark and empty deep space of the universe, two twin star rangers are slowly slowing down, approaching Ganymede.

"Report, the opposing warship has entered the detection range of our radar!" Gemini Wisdom Brain suddenly sent a report.

"Huh? It's finally here! The size of the opposing fleet? The two captains were shocked.

"One, no other sources found!"

"Hmm...... Keep an eye on your surroundings to prevent your enemies from having hidden powers! ”

"Yes!"

……

It wasn't until 2 hours later that the Return detected the signal of the other party's spacecraft, and from the detection range, Ma Zhe's gravitational wave radar from the two probes was obviously not as good as the shipborne model of the Gemini civilization, and it belonged to a pair of "myopic eyes".

However, close to this distance, in the case that both sides have gravitational wave radar, all kinds of stealth technology have lost their effect at the moment, unless they can shield their own gravity, otherwise at this time, they can only look at each other affectionately, but after all, it is an itchy stage that can be watched from a distance and cannot be blasphemed......

And if you want to shield yourself from gravity, it is definitely difficult to climb to the sky.

Gravitation is the only one-way force among the four fundamental forces that only attracts and does not repel!

According to the general theory of relativity, gravitation is the distortion of space by the mass of an object, so the real anti-gravitational force is to smooth out the space distortion caused by the mass of matter, and by extension from here, if the anti-gravitational force can be achieved, then in fact curvature navigation can also be done, because the two are essentially the same principle.

Even further, if the anti-gravity force is cracked and the four fundamental forces are unified, then even the legendary theory of great unification is expected to be overcome!

If one side really conquers the anti-gravity supertechnology, then we won't see both sides spending months just to cross the ocean to see you......

But by the time you see the other person, you're dead......

To put it simply, shielding one's own gravitational pull is a rather lofty technology! At least neither side sees the shadow of this technology from the other, otherwise either side will immediately flee.

It is precisely because of the almost unsolvable gravitational wave radar detection methods in the current civilization stage that the battlefield information of both sides tends to be transparent!

At the detection range of 100 million kilometers of gravitational wave radar, without the cover of complex celestial bodies, any sneak attack and ambush is basically impossible to complete, and at this distance, if there is no faster-than-light attack means, then long-distance engagements are basically blind shots with a high probability.

Any attack you launch, whether it's a heat-generating particle beam or laser weapon, a relatively slower kinetic weapon, or a gravitational ray, will be clearly detected by the opponent's various detection methods and calmly dodged in advance!

Therefore, the current situation of the two sides is to find the distance > the range of weapons > lock the distance, and in this case, there is no way to talk about long-distance engagement.

Therefore, space warfare at this stage of civilization basically needs to be close to 10 light seconds, that is, within 3 million kilometers, in order to make an effective attack.

Under deliberate control, the Return and the two Rangers arrived in the Callisto field at about the same time, with Calymede facing each other tens of millions of kilometers apart.

Since they didn't know the opponent's attack method and attack distance, both sides were very careful to turn on the low-power force field shield at the moment, guarding against a possible sneak attack.

Naturally, the force field shield of the Return surprised the Gemini civilization very much!

"It's strange, the other party's protective technology is also a force field shield? And in the radar detection, why is the graviton wave imaging emitted by the opponent's shield so similar to that of our civilization? The captain of the Feather Clan said with some surprise.

Before stepping into the interstellar civilization, the initial development of civilization was relatively independent, so it gave birth to very different technological routes, such as the graviton technology and force field shield of the Gemini civilization, while Proxima Centauri developed a peculiar bioaugmentation technology.

If you look at the normal development of the earth, you may be able to develop protective technologies such as magnetic shields or plasma shields.

Or...... The Earth civilization discovered the graviton and followed the same path as the Gemini civilization to develop the force field shield, but in the process of improving the equipment, the two sides will be quite different.

Therefore, it is not impossible for two civilizations to develop the same type of shield, and even the external characteristics of the shield are very similar, but it is ...... It's basically no different from winning the lottery!

Just when the Gemini civilization was surprised and inexplicable, the optical imaging systems of the two sides finally captured each other's images and completed the "first meeting"!

Ma Zhe looked at the two battleships of the Gemini civilization on the screen with a solemn face.

Among them, the cigar-shaped Sea Clan battleship is about 500 meters long, and the pitch-black paint is matched with more than a dozen hideous outboard gun muzzles on the hull, which is obviously a space battleship that pays great attention to offensive firepower.

What made Ma Zhe pay attention to the obvious and extraordinary-shaped triple helix main gun at the front of it.

Then he looked at the other Feather Clan battleship, which was painted in silver-gray and had a mirror-like appearance. Ma Zhe didn't even see the shadow of the weapon system on it, it was very weird.

The Gemini civilization is also looking at Ma Zhe's return.

In terms of shape, it is also a cigar type, but on the outside it looks very choled, full of irregular edges and corners, and the design is quite rough, even ugly!

"Humph! Sure enough, it's a barbaric civilization, and elegance probably doesn't exist in the dictionary of their civilization at all, and those who don't know think it's an interstellar refugee from somewhere! The captain of the Yu clan looked at the battleship and couldn't help but say with disdain.

The Feather Clan has always had a high opinion of himself, and his pursuit of art and beauty is also quite demanding, and when he saw the return with no sense of beauty, he had the urge to immediately turn it into a fire.

"Strange, why can't you see its weapon system? Could it be that you are the same type of battleship? "The captain of the Sea Clan doesn't have so many feelings, the Sea Clan has always been a pragmatist, no matter whether it looks good or not, it is the truth that it is powerful enough!

Soon, the two sides carried out the last communication before the war......

"Ha~ Two friends, long time no see! I slept like a month? It's a long journey...... "The Eight Knights" on the screen yawned big....

"Your Excellency Hachijo looks like he's got a lot of money in his chest! Hehe......" Captain Yu sneered.

The other party's pretending to be relaxed and arrogant style is very unpleasant, sleeping for a month before the war? What about the crooks?

Ma Zhe really didn't lie, he did go to some degree of "dormancy", and even now, strictly speaking, he hasn't woken up......

"No, no, I'm just a little impatient! So, can we get started? He looked excited.

"Waiting for you at any time!" The Sea Clan Captain is also not to be outdone!

"Good! According to the agreement, the first battle will be a battle for the planetary ground, the second will be a space battle for carrier-based weapons, and finally a space fleet battle.

So now for the first battle, the battle for the planetary ground, with Ganymede as the battlefield, except for the battleship itself, any weapon can be put into the battlefield! The first to destroy the opponent's base wins! Is there a problem? ”

"Huh? Any weapons other than the battleship itself? The captain of the Feather Clan sighed.

"Not bad! Other words...... The ship-borne weapons of the second game can also be put into battle! Ma Zhe said with a smile.

The two people of the Gemini civilization were stunned for a moment, and then after a little thought, they understood the purpose of this rule.

Generally speaking, carrier-based space weapons can also be used as air support in the ground battle for planets without atmosphere, and the power of weapons is much stronger than that of ground weapons, after all, it is a combat weapon to cooperate with the mothership and the enemy space battleship.

But if it is put into battle in the first game, it is equivalent to being figured out by the opponent the reality of its second weapon, then it is easy to be targeted in the second game, and lose the information advantage and strategic first!

However, they all understand that this is completely different from Tian Ji horse racing, and the three races are more important the further they go! The duel between the upper and upper sires is the winner or loser!

Two wins in three games is a joke in itself, and if you can't win the final fleet battle, what if you win the first two?

Is it possible to expect the opponent to keep his promises? All right...... Even if your character is strong enough and your opponent keeps his promises, but without a battleship, can you still swim to Earth from here with a rescue pod?

So from the very beginning, the Gemini civilization didn't pay attention to the rules of the best-of-three game at all!

What a clumsy ploy! The two captains sneered in their hearts.

The other party is obviously quite confident in his ground weapons, and wants us to dispatch carrier-based space weapons to support when we lose on the ground battlefield, so that the right party can increase the chips for the second competition!

Arrogant! Naive! Think you're going to eat us?

"Yes! We have no opinion at all, and we hope that your ground forces will not disappoint me too much! The Sea Clan captain sneered.

Ma Zhe didn't say more, nodded with a smile and hung up the communication.

……

Shortly thereafter, three warships from both sides simultaneously ejected an assault landing craft and charged towards Europa.

Taking advantage of the time when the landing forces of both sides approached Europa, the warships of both sides were not idle.

Almost simultaneously, they began to spread miniature probes to Ganymede and the vast star fields around it for tens of millions of kilometers! Targeted battlefield information coverage and intelligence masking!

Neither party has expressed any objection to this, the agreement is an agreement, but as long as there is an opportunity to see the flaws or weaknesses of the other party, neither party will mind ending the game early!

A rabbit may race against a tortoise, but if a rabbit finds out that its opponent is a snail, it probably won't mind stomping it flat at the start!

Unlike Gemini, Ma Zhe's miniature probe is just a show to attract the attention of the other party, and the surrounding airspace has long been filled with space spies disguised as cosmic dust.

When the other party's probe was still sailing by inertia, Ma Zhe had already begun to watch the two warships inhumanely......

In the captain's room of the Return, a 30-degree holographic model of the Sea Tribe battleship without dead angles is being built at a rapid pace......

And Ma Zhe's face showed his signature captain-style smile......
