The alien fleet flying at high speed did not retreat, and the Yuzhou battle group also had no room to retreat, and the moment the enemy entered the firing range, the Yuzhou battle group opened fire with full firepower, and shells, missiles, and lasers pounced on the enemy at the same time.

The alien fleet was not ambiguous and immediately launched a counterattack.

Probably because they were afraid of being wiped out by the super cannons, the enemy's warships were very scattered, and the result was that the firepower of the Yuzhou ship group had to be averaged to all enemy ships, and the firepower assigned to each enemy ship was not strong.

While the fleet opened fire, the artillery emplacements were also ready to fire, and all launchers were aimed in the direction in which the enemy ships were flying...... Want to dodge the Super Cannon with speed? It's a beautiful thought!

Several alien warships were hit by the Yuzhou battle group, some crashed and some lost control, but the remaining enemy ships did not retreat at half a point, and still advanced at full speed against the firepower of the Yuzhou battle group.

The Yuzhou battle group originally wanted to use firepower to force the enemy to give up the attack, but the alien fleet had no intention of giving up at all.

The distance between the two sides is getting closer and closer, and after a while, the Yuzhou will enter the range of fine light.

At this time, the Yuzhou battle group suddenly climbed up and took the initiative to break away from the battle.

Ye Han was stunned for a while, but soon understood that the Yuzhou was carrying out Huo Qiang's order to avoid losing more warships.

As for the super artillery, hehe, the cost of an artillery array is worth half a battleship at most, and from a tactical point of view, there is nothing wrong with protecting the artillery array with a fleet, but from an economic point of view, it is not an ordinary stupidity to do so.

With Huo Qiang's order in advance, the Yuzhou did not have to defend Ceres, and naturally it would not fight the enemy for an artillery array.

Only a few minutes later, the first enemy ship flew into the artillery firing angle, its altitude was extremely low, and a hill was chosen as cover, and when it could be directly hit by the laser, the distance from the artillery array was only a few tens of kilometers.

At the current speed of the enemy ship, it only takes more than ten seconds to fly over the artillery array.

The artillery array was ready to shoot for a long time, and the radar locked on to the enemy ship for the first time, and then the artillery array suddenly opened fire, and tens of thousands of laser beams instantly hit the enemy ship.

In order to ensure the firing range, there are hundreds of thousands of lasers on each artillery array, and one or two hundred thousand lasers are only a small part of the entire artillery array.

The laser penetrated the enemy ship, but the laser is a directed energy weapon, has no physical impact ability, and the speed of the enemy ship far exceeds the escape speed of Ceres, and the result is that although the enemy ship lost control after being destroyed, it still continued to fly according to the previous trajectory.

People can think of this, the control system of the artillery array is not so smart, it mistakenly thinks that this enemy ship is still combative, so it continues to lock on to this enemy ship, and there is another laser shot in tens of thousands.

At this time, several other enemy ships flew out from behind the mountain in unison, and the artillery array fired in batches and in turn, destroying one enemy ship after another in the air.

Of course, these "dead" enemy ships are all moving according to the previous trajectory, unless the entire battleship is completely vaporized, the rigid control system will always judge that the enemy ships in the air are still threatening, and will continue to bombard them with lasers.

The first enemy ship attracted a great deal of firepower, creating an extremely short period of opportunity for the following enemy ships, which took advantage of this fleeting opportunity to launch the heaviest attack on the artillery position.

For a while, countless thin lights fell into the artillery array, cutting off everything in its path, and the firepower from the artillery array plummeted.

Everyone knew that it was only a matter of time before this artillery array was finished and completely destroyed, but the aliens did not rush to kill them all, and they didn't know if they didn't have time or deliberately let go of the artillery array...... This is obviously impossible, and the aliens will only think that the artillery array is not completely destroyed.

However, this judgment was soon shattered by the aliens, as their ground forces attacked again, this time without a counterattack from the defenders or a bombardment from the fleet, and the ground forces rushed all the way to the vicinity of the artillery position.

At this time, the condition of the artillery array was very bad, half of the launchers were destroyed, the circuits were also broken a lot, and less than a fifth of the launchers were still usable.

But the control system hidden under the artillery position was still intact, and the rigid control system did not know how to be flexible, and it faithfully carried out the combat procedures, manipulating the remaining lasers to lower the firing angle and fire at the attacking ground forces.

The super cannon is not right in the air, but it is not impossible to fire flatly, it is just that it cannot be concentrated.

The giant insects and enemy soldiers are not as powerful as the alien battleships, and the lasers sweep through them, and they suddenly turn into a piece of minced flesh, and they can't die anymore.

All the people who witnessed this scene couldn't understand the aliens' thoughts, they all looked like this, the fleet came again, the entire artillery array was completely abandoned, and then the other artillery array could only control the small half of the sky of Ceres, and the aliens could come and go without saying that they wanted to come and go, at least they could land on Ceres without hindrance, and they could not say that they had the strategic initiative, at least they had some of the initiative.

What does it mean to still insist on ground advance at this time?

The aliens were more persistent than everyone imagined, and soon organized another wave of attacks, but this time they did not come close to the artillery position, but stopped from a safe distance, and the giant insects that accompanied the army immediately dug their burrows and quickly burrowed into the ground.

The enemy soldiers followed the giant worm, and it didn't take long for this wave of enemy soldiers to burrow into the ground...... The place where the hole is drilled is a bit far away, and even if the giant insect has an amazing digging ability, it will not be able to dig a place for a while.

In this way, the giant worm dug for two days in a row, and finally dug the tunnel under the artillery emplacement, and an enemy soldier was lucky enough to dig into the control room of the artillery emplacement, successfully cutting off the control of the system to the launcher.

At this point, this broken artillery array fell into the hands of aliens.

Yuzhou found from the monitoring that the enemy soldiers are very protective of the control equipment, this situation immediately caused Yuzhou to attach great importance to the situation, the situation is very obvious, the alien goal is not to destroy the artillery array, but to occupy the artillery array and then understand the artillery array, and there may be the idea of replicating the artillery array, this is not a good phenomenon, Yuzhou reported the situation to the Nanzhou at the same time, decisively detonated the nuclear bomb placed under the artillery array.

In the center of the artillery array, which had just been occupied by the enemy, a dazzling bright light suddenly burst out, and then there was a wave of shaking of the heavens and the earth, and a powerful nuclear explosion overturned the entire artillery array, turning the location of the artillery array into a half-kilometer-deep crater.

The early placement of nuclear bombs is only a necessary means of prevention, which is nothing to mankind, the simplest conventional tactic.

But it was different for the aliens, the artillery array that had just arrived flew again, and the aliens were so aggrieved that they almost vomited blood, and in their excitement, they immediately ordered the ground troops to continue to attack the next artillery array.
