The two sides are 30 million kilometers apart, and because they are on guard against each other, neither side is very fast, and they are approaching at a speed of 200 kilometers per second.

In about forty hours, the two sides will meet head-on.

Twenty hours later, the two sides were 15 million kilometers apart. Xiao Yu began to release the detection satellite and hid in space first.

Every second, thousands of satellites are thrown into the air by Xiao Yu, and the functions of these satellites are not very many, mainly responsible for detection and monitoring, preventing the other party from launching a sneak attack with the help of the dark cosmic background.

Of course, because Jin Ye foresaw in advance the importance of information in space warfare, Xiao Yu's satellites also have a simple attack function on them, three machine guns, mainly to destroy the enemy's satellites and destroy the enemy's information channel.

A large-scale space war will be unlike any kind of war on Earth. Because its battlefield is extremely large, it may occupy a radius of hundreds of thousands of kilometers, and it is three-dimensional, in this case, it will be impossible to rely on the detection ability of a single spacecraft to gather intelligence. So the presence of detection satellites is a must. This helps Xiao Yu to grasp the various situations of the overall situation on the battlefield, so as to better command the battle.

Although Xiao Yu has not experienced any large-scale space war, with the help of tens of millions of computer simulations, he has also deduced the most reasonable way of space war.

Thirty hours later, the two sides were eight million kilometers apart. In this position, the Sun and the Voyage gradually slowed down, leading the escort of more than 10,000 village-level and township-level spacecraft out of the main force. All the remaining spaceships surrounded the Tianyuan and rushed towards the battlefield with murderous energy.

It is impossible for Xiao Yu to put all his forces into the battlefield at once. When the war breaks out, these spaceships will become Xiao Yu's rear.

Thirty-five hours later, the two sides were four million kilometers apart. The first wave of encounters is coming.

The first to engage in a confrontation were the satellites of both sides.

The satellites of the alien civilization have no attack function, once it discovers the satellites of Xiao Yu's fleet, it will immediately transmit the data back to its own spacecraft fleet, and at this time, a laser will come and destroy the satellite.

In the battle for satellites, Xiao Yu undoubtedly has a great advantage, as soon as the satellites of the two sides meet, Xiao Yu's satellite can directly launch a machine cannon to break the satellites of alien civilizations into pieces. After all three machine guns are launched, Xiao Yu's satellite can also act as eyes and ears, and the satellites of alien civilizations can also send the coordinates back to the flagship, allowing Xiao Yu to command the spacecraft to destroy the satellite.

As the distance between the two sides got closer, a large number of small missiles were launched by both sides. These missiles are extremely fast and extremely stealthy, which makes it difficult to intercept them, and it is also a good deal to use these small missiles to deplete the opponent's fuel reserves.

At this time, the information superiority brought by Xiao Yu's satellite is reflected, and there are often three small missiles that hit the alien fleet, and only one small missile hits Xiao Yu's fleet. In addition, many of Xiao Yu's ships in the fleet have new Edelman-like alloy shells, and the damage rate of the two ships has reached 1:20.

For every time Xiao Yu's spaceship was damaged, about twenty alien spaceships were damaged.

Forty hours later, the two sides were 500,000 kilometers apart, and the high-velocity machine guns that had been specially modified by Xiao Yu began to fire. The overwhelming barrage of bullets began to rush forward. These bullets have an extremely high muzzle velocity and are much smaller, almost the same as normal bullets on Earth, so they will be impossible to intercept.

These bullets rely mainly on extremely high kinetic energy to generate destructive power. This will be the most commonly used and most abundant weapon in interstellar warfare at this stage.

Before the two sides actually start to make contact, a large number of miniature missiles and an overwhelming deluge of bullets will be the first to hurt the other side. Before the protective shield technology is really put into practice, micro missiles and ordinary bullets will become the most used weapons on the battlefield because of their excellent characteristics of being difficult to intercept and cheap to cost.

This conclusion can be reached thanks to the countless deductions made by Xiao Yu's huge computing power.

Xiao Yu conducted a large-scale simulation of this doomed interstellar war, in which Xiao Yu tried tens of thousands of different ways of warfare, and chose the most economical and efficient one among them. That is, conventional weapons are used as the main combat power, high-energy laser cannons are used as high-end combat power, miniature laser guns are used as the main defense force, and large-yield nuclear bombs are used as the ultimate combat power.

Xiao Yu didn't know if the other party also had this understanding, but after all, the other party was also a civilization, and there would definitely be countless amazing people among them, and their understanding of war was estimated to be the same as his own, that is, they were likely to use the same tactics as themselves.

Another half an hour passed, and the two sides were 100,000 kilometers apart. At this distance, if the other party also adopts the same means as Xiao Yu, then Xiao Yu is now about to meet the strike frenzy of miniature shells and ordinary bullets.

"Do not pin your hopes of victory on the stupidity of the enemy. Xiao Yu muttered silently, as a civilization, the other party will definitely not be weaker than himself.

Xiao Yu fired three giant flashbangs! This is a kind of ammunition specially developed by Xiao Yu to illuminate in space, powered by a nuclear fusion engine, which can provide bright flashbangs for a radius of tens of thousands of kilometers.

Three huge munitions were fired from the launch rack of the Tianyuan spacecraft and flew to their respective positions. Thirty seconds later, three giant flashbangs exploded together, and suddenly, it seemed that three small suns suddenly appeared in space, illuminating a radius of hundreds of thousands of kilometers.

With the help of the bright light emitted by the giant flash bomb, Xiao Yu's optical equipment observed the front, and a dense torrent of bullets was flying towards him, and it was expected that ten seconds later, these bullet torrents would hit his spaceship head-on!

"Sure enough, you can't underestimate the enemy, and they really have mastered such combat skills. However, the aliens may not have a new type of Edelman-like alloy, and I just don't know if they can withstand the torrent of bullets from me. Xiao Yu secretly thought that the Water Blue Star Fleet had a new type of Edelman-like alloy, and the damage that these bullets could bring was really limited, and Xiao Yu didn't even need to dodge these bullets.

Two minutes later, two torrents of bullets crashed into Xiao Yu and the aliens' fleet. Xiao Yu's fleet formation was a little scattered, but there was not much damage, but the alien spaceship once again damaged hundreds of township-level spaceships and more than forty village-level spaceships.

It can be said that in the first encounter, Xiao Yu completely suppressed the alien fleet.
