The outsiders were defeated and fought repeatedly, and finally captured the artillery array, but the artillery array was sent into the sky by nuclear bombs in a blink of an eye, and all the giant insects and servants near the artillery array followed into the sky, which was simply a heavy loss.

It was supposed that the aliens should stop for a while, but they didn't, and immediately organized another ground force and set off for another artillery position.

"I just don't know whether to live or die!" Ye Han, who was far away on the Thunder Mountain, commented.

Don't look at the aliens succeeded once, but that was the result of Yuzhou's refusal to fight hard, now two full days have passed, Nanzhou will be able to return to Ceres in two more days, but no matter how small Ceres, the diameter is more than 1,000 kilometers, from the No. 1 artillery array to the No. 2 artillery array, the straight-line distance is not less than 1,000 kilometers, and the actual distance is 1,400 kilometers.

No matter how fast the giant insects crawl, they can't climb in two days, not to mention that the Yuzhou battle group can't let them climb so comfortably, and they have already prepared on the road, just waiting for the enemy to drill into the trap.

Aliens are not stupid in their brains, they just don't understand the means of human beings, but after so many battles, they should know some if they don't understand it, as long as their IQ is normal, they shouldn't continue to attack.

However, the aliens' desire to monopolize Ceres is very strong, and for this they would rather suffer huge losses.

The aliens knew very well that the human fleet was about to return, and in order to buy time for the ground troops, the alien fleet was divided into two, half of which stayed on Ceres to continue to support the ground forces, and the other half left Ceres, and all the warships acted separately and took the initiative to meet the returning human warships.

As the battle progressed from space to the ground and from ground to space, the military operations around Ceres between the two sides became increasingly complex.

Also to buy time, the aliens left all the bug planes to the ground forces to speed up the transition of the ground forces.

The aliens left behind did not dare to slack off, and immediately organized troops to attack, thousands of insects crawled with enemy soldiers on the fuselage, and car insects and armored insects shrunk into a ball and hung under the insect machine.

Maybe it's because the giant insect is too heavy, or maybe it's to reduce the burden, the insect machine is not a one-on-one hanging giant insect, but three or more insect machines cooperate, I don't know what to use to catch the giant insect and then fly at low altitude, the speed is not very fast, even if there is an accident on the way, it will not fall to death the giant insect.

Ye Han thought that the enemy was doing this to prevent the attack of the Yuzhou battle group, but before the Yuzhou could make a move, the insect machine in the transition had an accident first, and an insect machine suddenly fell out of control, and the enemy soldiers on its back fell like dumplings.

The other two insect machines immediately tightened the insect net, and several nearby insect machines rushed up to pull the insect net together.

This situation is a bit weird, why do you still have self-destruction? And as soon as there is a problem here, the position will be filled immediately, which must have been prepared for a long time!

The fallen insect machine fell to the ground and bounced a few times, and it didn't look like anything wrong with it, but it couldn't fly anymore, and I didn't know what was wrong.

At first, Ye Han thought it was a recurrence of an old injury, but soon found out that this was not the case, because other insect machines also had similar problems, falling down one after another, and after falling to the ground, they could move a few times at most, and none of them could fly again.

This is interesting, Ye Han immediately found out the information of the insect machine, not to mention that he really let him find out some clues.

Things have to start with the principle of flight of the insect machine, which uses vibration to throw away gas molecules to fly, in other words, the gas molecules are the fuel of the insect machine.

As for whether the fuel was refueled by aliens or accumulated by the worm machine itself, no one knows.

According to Beiyuezhou's research, the insect machine is a relatively primitive way of flying, and its efficiency is far less than that of jet engines that use chemical fuels, and it can only fly in weightlessness or microgravity.

Seeing this, Ye Han understood, don't look at Ceres's gravitational attraction is so low, but it is also a big burden for the insect machine, and the insect machine does not fly by itself, but also has to bring so many enemy soldiers and giant insects, which further increases the burden of the insect machine.

It's like a person carrying dozens of kilograms on flat ground, at most, it is a little heavier, but if you do this on the plateau, it is not much different from looking for death.

In other words, those fallen worm machines either ran out of fuel, or they were too heavy to crush their backbones.

It is better to be tired of the insect machine than to send the ground troops to the front line, Ye Han has a new understanding of alien determination.

It is said that there is a problem with the insect machine, and it is the best time to solve this group of enemies, but the Yuzhou still did not move and remained silent.

Ye Han knew that the Yuzhou must be waiting for the best time.

The enemy continued to advance, more and more insect planes fell, and more and more enemy soldiers remained on the road, and the Yuzhou finally felt that the time was ripe and raised its altitude to open fire on the enemy.

The enemy's ground forces did not care, even if they did not fight back and did not stop, and their only reaction was to accelerate forward.

However, the fleet left by the aliens moved, and quickly flew over the ground troops, and had an air-to-air bombardment with the Yuzhou battle group.

At the moment, the distance is still far away, beyond the range of the naval guns of both sides, and there is no problem in hitting the enemy giant worm or something, but the battleship is not like that, even if it hits the enemy ship, it will not cause much damage, unlike your life-and-death battleship confrontation, but a bit like a crappy performance in a third-rate science fiction movie.

The Yuzhou simply ignored the alien fleet and opened fire on the ground, giving priority to destroying the enemy's living forces.

The alien fleet was also unambiguous, and all its firepower was aimed at the Yuzhou battle group, trying its best to contain the Yuzhou battle group.

In this case, the ground forces of the aliens still did not give up and continued to advance despite huge losses.

The aliens soon found out that this would not work, and if they continued to do so, the ground troops would die before they could advance to the designated position.

In desperation, the aliens ordered the ground troops to stop advancing and rely on the favorable terrain to resist human strikes, and then the giant insect dug a hole in the ground, intending to dig all the way to the bottom of the artillery array, and then rush out of the ground in one fell swoop to completely occupy the artillery array.

This hand is indeed very effective, at least there is no need to face human air raids, the only drawback is that the speed is too slow, the distance in a straight line is six or seven hundred kilometers, let alone three days and two days, even ten days and half a month can not be dug through.

Soon after, all the alien ground forces went underground, and the follow-up troops also burrowed into the ground, and only the alien fleet remained in a low-altitude orbit.

Two days later, the first human warship to return to Ceres, but a few hours later, the Nanzhou returned, and the other ships returned over the next few days.

For the sake of safety, the alien fleet, which originally wanted to hold out a little longer, had to evacuate Ceres, leaving behind all the ground troops that had burrowed into the ground.

Fortunately, the ground forces are all hidden underground, and there is no need to worry about air raids by the human fleet.
