In the eyes of those fleet executives, the previous attack might be the Zerg's final counterattack.
After all, the previous artillery preparations had indeed severely damaged the Zerg, so that the number of troops they could use reached a low limit.
As a result, they immediately issued an order for the Marine Corps to expand outward.
Under the protection of the Marine Corps, the engineers directed the intelligent robot to build a new protective wall twenty kilometers away.
This is also a helpless thing. Although the Blue Star Alliance has been moving beyond its home star for a thousand years, its development speed in AI intelligence is still very slow.
Those intelligent robots are good at doing simple tasks, such as mining, simple maintenance, etc., but if they need to perform further self-judgment work, it will be very difficult.
Take the work of building protective walls as an example. Since the protective walls are built in continuous, uneven hilly areas, it would be difficult for those intelligent robots to complete this kind of work without human command.
They can't even judge where the anti-aircraft tower should be built.
The only good thing is that the existence of intelligent robots has reduced the amount of repetitive, simple and boring work for humans.
All it takes is an engineer to delineate the locations of protective walls, air defense towers, etc., and those intelligent robots will swarm forward, wield high-energy laser welding guns, and weld the steel plates together to form a protective wall.
These ten-meter-high protective walls can effectively resist the jumping impact of mantis insects.
After all, mantises can only jump to a maximum height of three meters, and soldiers can easily shoot them while standing on the protective wall.
But just when the protective wall was repaired, the Zerg attacked again.
And this attack is by no means comparable to the previous ones.
The first thing was the flying dragon insects flying over from the sky in dense numbers.
These flying dragon bugs can be regarded as relatively advanced units among the Zerg tribe. They are about three meters long, have a pair of bat-like wings, and can spray an extremely acidic liquid.
These flying dragon insects immediately annihilated the Nighthawk fighter jets patrolling the air for reconnaissance, and then ignored the continuous spider mines in front of the protective wall and went straight over the protective wall.
They didn't even pay attention to the human soldiers shooting wildly at them below and the air defense towers that kept firing missiles, and rushed straight towards the landing ship.
There is always a price to pay for breaking through in the direction of humanity.
Humans deployed a large number of air defense towers to knock down a large number of flying dragon insects to the ground.
But at this time, the faces of the fleet's senior officials turned livid, so just as the flying dragon bugs were attacking the landing ship, the ground under the self-propelled heavy artillery tanks suddenly bulged, and these big guys weighing hundreds of tons were thrown away. They flew out one after another.
Giant worms hundreds of meters long emerged from the ground and dealt a heavy blow to humans!
After drilling out of the ground, they immediately sprayed out rich hot oil in all directions. The hot oil fell on the ground, tanks, and air defense towers, and then burned. The extremely hot high temperature quickly melted the steel. Burn human soldiers to ashes.
A large number of clone soldiers screamed and fled in the flames. As for those soldiers sitting in tanks and air defense towers, even if they jumped out desperately, the hot oil on their bodies would still turn them into burning torches.
These giant worms appeared for the first time in the war with humans. They are a new type of worm!
In less than a minute, most of the more than 300 self-propelled heavy artillery tanks deployed near the landing ship cluster were lost.
At this time, an endless swarm of mantises appeared from the horizon and rushed towards this side crazily.
Those flying dragon insects that successfully penetrated the defense immediately launched an attack on the landing ship docked on the ground.
There is no doubt that this is the counterattack that the Zerg have been holding back for a long time.
In other words, from beginning to end, this is a trap for humans.
The flying dragons raided the landing ship, cutting off the human retreat route. The giant worms that had never appeared before directly destroyed the self-propelled heavy artillery tanks and air defense towers, providing cover for the attacks of the mantises and flying dragons.
At this time, the mantis insects had already rushed into the minefield. As the creaking mechanical sound sounded, the dense spider mines jumped up from the ground and rushed towards the insect swarm. After that, they turned into a violent explosion of fire. Bring dozens of mantises around him into the underworld.
The human soldiers standing on the protective wall were already firing at the swarm of insects. The dense high-energy projectiles penetrated into the insects at speeds of several Mach, blowing them to pieces.
This war has been intense from the beginning.
Seeing the changes on the surface, a large number of Nighthawk fighter jets took off one after another and started a fierce fight with the flying dragon insects to prevent the landing ship from being damaged.
The human warships outside the atmosphere also began to pour artillery fire on the ground.
Weapons such as high-energy particle cannons, mass bombs, small mushroom eggs, etc. continue to bloom their own brilliance on the ground.
But at this time, in some concave valleys in the hilly areas, huge, mushroom-like fleshy buildings stood up. They emitted layers of blue light that spread upwards, making the tops of the mushrooms keep getting brighter.
When the brightness became too bright to be seen directly, a blue meteor was immediately generated on the top of the mushroom and shot out of the atmosphere.
When thousands of blue meteors rose from the ground and kept approaching, the senior leaders of the human fleet naturally understood.
These meteors containing extremely high energy are probably the Zerg's counterattack against the human fleet.
"Speed Evasion!!!"
Since energy shields, ion shields, electromagnetic shields and other technologies have not yet been activated, when facing enemy attacks, the only things human warships can do are two things.
One is to avoid the ballistic trajectory of enemy attacks, and the other is to rely on its strong hull to resist.
This is also a helpless thing.
The Zerg fire blue meteors too fast.
The first wave of thousands of blue meteors had just broken through the atmosphere, and the second wave of thousands of blue meteors were immediately generated and rose into the sky.
Although there is no air in outer space and sound cannot be transmitted, the battleship was hit by a blue meteor and suddenly exploded, turning into countless blue streamers splashing in all directions. It looked extremely spectacular.
But such a spectacular scene shows that mankind has been severely damaged.
Although the exploration fleet poured a lot of firepower at those fleshy buildings in the first place.
After only three waves of blue meteors were emitted from many fleshy buildings, they were blown into fragments all over the sky. Chitin armor plates were intertwined with broken cellulose tubes. Body fluids splashed everywhere, evaporated instantly, and thick black mist rose.
The whole scene was like a super boiling ink bag being burst.
