Gravitons are still used as imaginary particles that transmit gravitational attraction at the current stage of Earth civilization, but they have been widely used in interstellar civilizations. If the universe is seen as an ocean, then gravitons are seawater that exists in the universe and exert the same pressure in all directions of space, while antigravitons can counteract the pressure of seawater in one direction with the same force. In one direction where there is no seawater pressure, the object in it can be pushed forward by the pressure in the opposite direction.

In the universe, this water pressure is the speed of light. So in fact, the anti-graviton engine is not located behind the starship, but acts as a barrier against gravitons in the direction of the starship.

Of course, the anti-graviton engine alone is not enough to ensure the speed of light movement of the starship, in conventional space, once the maximum speed of light is reached, the mass of the object will tend to infinity, although the kinetic energy is provided by the graviton of the entire universe, but the starship itself cannot withstand such energy, and it also needs an energy field that wraps the starship and is semi-independent of the universe. In addition, at the speed of light, conventional observation methods are ineffective, in order to ensure the safety of navigation, it is also necessary to have neutrinos, tachyon and other particle information receiving and analysis terminals, in addition to a variety of corresponding supporting armor technology, ecological speed, life support technology and so on.

In short, interstellar travel requires more technology than a primary civilization can imagine. The fact that the First Civilization can be classified as an interstellar civilization means that if it is not fully operational, it has at least fully mastered these technologies. All that's left is to assemble all of this technology onto the starship.

As the most important of all technologies, anti-graviton technology is not only a force that allows starships to gallop in the starry sky, but also a high-quality energy. Even if it can't be mounted on a starship yet, it can achieve some ultimate effect on its own - once released, the gravitons in a certain area are blocked, and the unbalanced force will squeeze out objects within the range at extremely high speeds.

The reason why it is not the speed of light is that the antigraviton does not have precise manipulation and cannot perfectly block the force of the graviton. But even if it is only partial, its speed is far beyond the limits of the primary civilization. If the effect of the antigraviton were not applied to all matter, the friction between the object and the air at this speed alone would be enough to turn to ashes.

It's just that...... All the means and effects used by the First Civilization are also in the calculations of the chess players, who know more about the power of antigravitons than the First Civilization itself, and have enough experience using this power.

An antigraviton eruption that is at a sufficient distance away from space is equivalent to a powerful shock wave, and the effect of emptying a given area is incomparably better. However, in a universe with dense gravitons, the antigraviton can act in a limited range and dissipate rapidly, so as long as you keep a sufficient distance, you will not be affected at all. And for the starship, which is designed to fly at the speed of light, the thrust generated by using the anti-graviton engine as a bomb will not have the slightest impact on the starship.

Even on a planet with dense matter, because in the range of anti-graviton, all objects regardless of mass or size gain the same velocity, and all the associated forces are also blocked by anti-graviton, so it can be regarded as the entire space being pushed out together, even if it reaches a speed of thousands or even tens of thousands of kilometers per second, the objects within the range will not be damaged in any way, and the only possible lethality may be to suffocate and die because of the sudden transfer of organisms from the ground to the universe.

But in this space constrained by an invisible barrier, the huge thrust of the anti-graviton is forcibly blocked, and all objects are squeezed onto this barrier that cannot be moved synchronously, which is equivalent to the matter within the range of the anti-graviton hitting the barrier at high speed, not to mention the sound beast as a living organism, even the starship can definitely not afford it.

It's as if the chess players hidden in the depths know that the First Civilization has such weapons that are extremely dangerous to living organisms, so they use this space to limit the balance, so that the anti-graviton generator device has changed from a powerful killing device to an extraordinary means of dooming together.

But the First Civilization was forced to use this method because of the inevitable need for chess player pairs. The only room in your own hands is to use the starship's physics engine to counter the thrust of the anti-graviton. But they have room for pairs, and so does the other side.

Antigravitons are not penetrating, so when they come into contact with the ground where there is no void, they explode into the air on the one hand, and flow around like a liquid on the other hand, until they are reflected into the air again after touching the invisible barrier at the end of the ground.

Everything above the ground is pushed in front of the barrier in the air with absolute force, but because the starting point of the force is on the ground, there is no influence at all below the ground.

The First Civilization was completely ineffective, but not completely destroyed. All the Sound Poppers on the ground and in the sky are gone, but new Sound Poppers are pouring out beneath the ground. This is the result of a pair of players.

For the chess players on Qiu Yu's side, this move is to pay the chess piece of the First Civilization in exchange for the effect of destroying most of the blast beasts. For the opponent's chess player, this pair is a bit of a loss, but it is still within the tolerable range, after all, outside of harvesting the most troublesome civilization, the plan to attack the underground has not been affected in any way.

It's just that the game is not judged by the moves you can see in front of you......

The ground cleaned by antigravitons is almost absolutely flat, different from the relative sea level flatness on Earth, but rather a kind of flatness in the actual sense. As long as your eyesight is good enough, you can stand at any point in this space and see every other location without hindrance.

After the wreckage in the sky fell, a soundbeast poked its head out of the ground. Until then, it had tried to contain the vibrations of its body, carefully picking up every sound wave signal that might be transmitted by its own kind under the ground, but had found no information that could be understood by itself other than the sound of objects colliding.

After a long time, a strange emotion forced it to voluntarily burrow out of the ground, observing it with six pairs of compound eyes that were far less useful than sound waves.

The world in its eyes is like countless broken mirrors, each with a large number of overlapping scenes, through which it can clearly judge the distance of the target. But at this moment, no matter how much you turn your head, you can't find a target that can overlap in your field of vision.

There was nothing on the ground as thick and indistinguishable sand as there was a broken and strange starry sky in the air.

It didn't like the kind of world that was so empty that it made itself dizzy, and there wasn't a hint of the sound of the same kind. Although it was dark and unable to fly, there were countless voices of the same kind and several things that attracted it, so it was much better than this earthly world in every way. So after one last glance around, the vibrations on his body began to change from weak to strong, and the soft sand slid to the sides like loyal subjects who were prostrate and avoided in front of the monarch.

At the moment when he was about to completely sink into the ground, the loudspeaker beast was once again pushed by strange emotions, and against his will, he once again poked his head to the ground.

Before the image of the world was reflected on the eyes, a never-before-heard, but unusually familiar sound, pierced its body, like the echo of a fragile object torn apart......

"Master, are we really doing nothing?"

This is the sixth time Qian Xiao has asked the same question. Since he met Qiu Yu, Qiu Yu's calm often has only two possibilities, one is already winning, and the other is ready to take risks. With his own wisdom, Qian Xiao didn't think that Qiu Yu didn't say anything for more than ten minutes because of the former.

Based on the fact that he didn't get any response the first few times, Qian Xiao was more like venting his anxious emotions than seeking answers. So after Qiu Yu answered, he was still pacing back and forth, and after a few seconds, he suddenly realized what Qiu Yu seemed to say just now.

"Well, were you just talking?"

"The opposing player is in the game." After repeating this, Qiu Yu looked at the other allies who had reached the limit of uneasiness, "Get ready to fight." ”

At this time, most of the moves are also in the calculation of the chess players.

Because of the foreshadowing of several games, the earth civilization already has this almost blind confidence in its own words. In this game, I have gained a lot of places to show my strength, but this alone is the limit for other civilizations to follow the route they have set so far.

Limited understanding, civilizational estrangement, and self-pride do not allow oneself to become the leader of these allies. But neither they nor their own players regarded this game as a strategic game that only needed one brain. This is a chess game, a complex game in which all advantages and disadvantages are taken into account. Not being able to master all the pieces on your own is a bad situation, but on the other hand, your opponent is equally uncontrollable. This is an equal disadvantage for chess players, and especially for the near-omniscient weave of fate. However, for the chess players who have the same heart as the chess player, they have invisibly established a small but not negligible advantage.

What's more, Qiu Yu is better than his own players expected, and within limited conditions, he makes the opponent's players fall into small traps that are enough to wear out their advantages.

The complex deception and anti-deception are over, and the tricks that the opponent's chess players and chess pieces can use can no longer exceed the calculations that Qiu Yu can master, and the rest is just a step-by-step general......
