The short air raid was over, and the aliens lost dozens of worm planes, but thanks to Ceres' low gravity and sturdy carapace, most of the enemy soldiers who landed on the ground stood up, and only a few who were unlucky broke their arms and legs, and almost none died.

Maybe it was because they were worried about the next wave of air raids from humans, or maybe the number of insect planes was insufficient to take all the enemy soldiers away, so the aliens simply gave up the idea of low-altitude raids and let the worm planes put down all the enemy soldiers, and the enemy soldiers advanced on foot, and the worm planes followed at low altitude.

Well, if the armored bugs keep up, the aliens' tactics are to get out of the way with armored assault and air-ground coordination.

It's just that the armored worm was left far behind by the forward troops of the assault, and the vanguard didn't mean to wait, and continued to move forward after dropping the corpses of the insect machine all over the ground, which seemed to be quite a bit of a sense of eliminating all difficulties.

The Yuzhou was not accustomed to aliens at all, and the fleet suddenly climbed at the right time to take the advancing enemy forces into view.

Then it was simple, all the laser cannons of the six battleships fired together, and the lasers swept almost close to the enemy, and the enemy strikers who were still fine just now instantly rushed into the street, and countless enemy soldiers were quickly turned into charcoal by the laser, and then disappeared.

The low-flying insect planes flew like headless flies, but they also couldn't escape the pursuit of the laser, and most of them were killed and injured in a short time.

After solving the enemy forces, the Yuzhou ship group immediately lowered its altitude, and there was a ground artillery array to support the bottom, and the Yuzhou did not worry about the enemy ships catching up at all.

Of course, the height here is only relatively speaking, and when the fleet is at its lowest, the actual distance from the ground is also a hundred or dozens of kilometers.

With a diameter of nearly 1,000 kilometers and hovering in a low-altitude orbit of only more than 100 kilometers, Ceres directly filled the perspective on the side of the fleet, almost 1670 degrees, close to half of the circumferential perspective, and looked unusually huge and full of oppression.

But when the fleet is raised, it is different, if the altitude of the fleet is raised to a thousand kilometers, the angle of view occupied by Ceres is only more than fifty degrees, and only one-seventh of the circumferential angle of view, which looks much smaller than in low orbit.

Therefore, the angle of fire of the fleet at different altitudes is completely different, and the increase in altitude by 180 kilometers can expand the angle of fire a lot, and the Yuzhou took advantage of this to carry out a short surprise attack on the enemy and successfully destroy the advance of the alien ground forces.

The successive defeats have made the aliens realize that it is not so easy to knock down the artillery array, and in order to avoid greater losses, all the alien troops that landed have stopped advancing.

Soon after, the alien fleet that had been parked over the landing zone finally made a new move, and the fleet split into two, half moving in the direction of the artillery position, and the other half increasing in altitude and gradually moving away from Ceres.

The movement of the alien fleet attracted the attention of Ye Han and the others, because there was too little news in hand, although everyone had various speculations, there was no tone to indicate the enemy's purpose,

The enemy ships that were far away were not noticed for the time being, and everyone's attention was focused on the enemy ships moving towards the artillery array.

However, this enemy force did not cross the safety line, they stopped before coming into range of the super-artillery, taking care of the ground forces with the fire of the fleet.

After this enemy force moved, the ground security line moved a certain distance in the direction of the artillery position, but this distance was not long, and the enemy troops still had to pass through the danger zone of several hundred kilometers if they wanted to rush to the vicinity of the artillery position.

However, Ye Han believes that the enemy's purpose in doing this is not to cover the ground forces, but to deter the Yuzhou ship group! Because the current position of the alien fleet can control the medium-altitude orbit above the Yuzhou ship group, once the Yuzhou ship group increases its altitude, it will have to face the fire attack of the alien fleet.

Of course, no one worries about this, because the straight-line distance between the two sides is too far, far beyond the effective range of fine light, and it is greatly exceeded, unless the Yuzhou takes the initiative to approach the enemy, it is difficult for the alien fleet to threaten the safety of the Yuzhou battle group.

The enemy's ground forces finally had a new movement, and they advanced to the artillery emplacements in several directions.

The Yuzhou really didn't plan to fight the enemy to the death, and there was a way not to knock if it didn't knock.

The fleet waited patiently for a while, and after the enemy had entered the appropriate distance, all the guns on the remaining battleships were erected high, and a blast of artillery fire directly covered the enemy with artillery fire.

All the warships that returned to Beiyuezhou have undergone a major transformation, and replacing naval guns with laser cannons is one of the key points of the transformation, and the remaining naval guns of each ship are only equipped with nuclear shells.

It's just that there are no absolutes, the Nanzhou happened to leave the two battleships that failed to return to Beiyuezhou in Ceres, these two battleships are still dominated by naval guns, and there are still a large number of shells on the ship, which are just used to bombard the enemy.

So the two battleships fired at full speed, and the shells were smashed at the enemy like money, and there were several nuclear shells mixed in the middle of the ordinary shells.

A little later, shells fell.

Because the distance was too far, there was a great error in the landing point of the shells, and as a result, five or six hundred shells were hit, and less than one-tenth of them really hit.

It wasn't until the nuclear shells hit the ground that the situation changed completely, and another round of alien attacks failed.

The aliens finally stopped attacking, and it stopped for several days, but no one felt that the aliens had given up, because their ground forces were still gathering near the security line, and the fleet had not withdrawn to the landing zone.

At this point, the departing fleet turned around without warning, and it was getting faster and faster.

At first, no one noticed this anomaly, and it wasn't until the enemy army flew close to Ceres that they didn't slow down, and everyone realized that something was wrong.

With the current direction and speed of this enemy force, the closest possible distance to the ground was only a few kilometers when these enemy ships flew close to Ceres, and their position was just above the artillery array.

Ye Han immediately remembered the scene when he attacked the enemy ship on Ceres, and immediately realized the enemy's intentions - they wanted to learn from the original Thunder Mountain and use the battleship to make an ultra-low-altitude assault!

Everything is clear, the enemy did not abandon the offensive, but switched to a more effective way.

Ye Han wanted to remind Yuzhou, but he gave up after thinking about it.

What he can think of, Yuzhou must also be able to think of, because the control system of each warship has previous combat examples, people can't think of it, and the computer can also find a clue through comparison to provide reference for the commander.

Sure enough, only ten minutes later, the six battleships led by the Yuzhou collectively turned around, all facing the direction of the incoming enemy, and the enemy wanted to fight over, and he had to pass through the fleet first.

Ye Han could completely imagine that at this time, every gun chamber of the Yuzhou battle group was loaded with nuclear shells or artillery missiles with nuclear warheads, and just waiting for the enemy ships to fly closer, he would give the enemy an unforgettable and painful lesson.
