The ending was not perfect, but Ye Han was quite satisfied, and after ordering the fleet to cease fire, the three battleships flew away unhurriedly.

Before leaving, Ye Han didn't forget to send Albert a communication, telling him that he was done with his busy work here, and he should come over as soon as possible to pick up the air raid, so as not to leave a buffer for the aliens.

Albert almost vomited blood.

Ye Han didn't care what Albert thought at all, the assault fleet planned to circle back to the back of Ganymede, which would take a little time, Ye Han finally had some free time, and couldn't help but start wondering what the situation with the aliens was.

First of all, the defense of both Ganymede and Ganymede is empty, which is not to be said, it must be the undesirable consequence of the departure of the main force of the alien fleet, and this precisely gives the raiding fleet a chance.

Judging from the current situation, the warships and troops remaining on Ganymede are more than enough to control Ganymede...... It is likely that the Strike Fleet took control of Ganymede, turning the aliens into frightened birds.

This is not surprising, aliens are not very good at dealing with air raids...... It's not right, not only aliens, but also humans themselves are not good at dealing with air raids, and the natural advantages of air to ground are not to be talked about casually.

So as soon as the air raid on Ganymede began, the aliens who stayed behind realized that they couldn't hold Ganymede, maybe the alien nobles were greedy for life and afraid of death, or it could be that the aliens also knew what it meant to stay in the green mountains, so that the aliens who stayed behind on Ganymede made the absurd decision to flee here.

That's right, it's ridiculous, if the aliens stay underground honestly, no matter how strong the attack fleet is, it's not so easy to break into the underground bunker and run out directly in a spaceship, is this afraid that the human fleet won't know where you are?

Ye Han didn't dare to say how good his strategic vision was, but from his point of view, the aliens either stuck to the ground or left quickly, no matter how they chose, it was reasonable, but what about the aliens? If you don't keep it resolutely, you can't go happily, it's simply a typical negative teaching material!

However, human beings still do not know the superstructure of the aliens, and perhaps it is the delay of the multi-headed command that creates an opportunity for the assault fleet.

In addition to these speculations that don't know right or wrong, Ye Han's remaining thoughts are "offense is the best defense" and "destruction is always easier than construction." ”

Think about it, it has been a full decade since the Jingjiang incident, and only those few expeditions in the past ten years have been real attacks, and the rest of the time humanity has been on the defensive passively.

The result? The earth has been ravaged by giant insects, nearly half of the world's population has been lost, industrial and agricultural production has been regressed for decades, and the price is too painful to mention.

Delving into the reasons, it is an objective fact that human beings are defenseless and technologically inferior to aliens, but it is an indisputable fact that aliens have been on the offensive from giant insects to alien battleship landings to Ganymede, but human beings have to be passive due to various factors, which is also one of the extremely important reasons.

Perhaps the alien fleet that is about to engage the interceptor fleet is tasked with continuing to maintain military pressure on humanity, and in order to achieve this goal, the aliens even do not hesitate to empty Jupiter's defenses and send out most of the warships.

Thinking about it a little deeper, the aliens themselves may not want to do this, but the rapid growth of human space military power, and the mixing with the resistance group, make the aliens have to pay attention to the military strength of human beings, and if they do not send out the main force of the alien fleet, they will not be able to suppress human beings.

All in all, the reason why the aliens did this should not be so simple, as a result, the raiding fleet killed Jupiter in one go, but the alien fleet did not have time to defend itself.

Maybe the aliens didn't expect that humanity would progress so fast from the beginning.

After thinking about it for a while, Ye Han finally remembered what was going on and ordered, "Pick up the Donghai for me." ”

The Tokai, the flagship of the Resistance, was disguised as a destroyer, so it was also given a name for camouflage.

"Yes!" The communications staff officer agreed loudly, but quickly replied, "Report, the electromagnetic interference is serious, and our ship and the Donghai are on both sides of Ganymede, so they can't be connected for the time being!" ”

Ye Han grinned, and said in his heart that this sound really familiar: "Keep calling, when you connect, when will it be counted...... You don't need to call me after you connect, tell them to come back and continue with the landing plan. ”

"Yes!"

Ye Han pulled up the map on the back of Ganymede again, carefully pondering the next plan of action.

The main forces of the fleet have left, the bomb load and fire intensity of the assault ships are not very good, and the conditions for a large-scale air attack are no longer available.

However, the progress of the air raid was less than one-third, and there were a large number of air defense positions on the back of Europa, both openly and covertly, and the transport ships of the resistance groups could not approach at all, let alone engage in any landing, and if they wanted to land, they could only use airborne capsules or landing craft.

The assault ships brought some airborne capsules, but the number was so small that even the airborne division could not do one, and it was impossible to support the servants.

Besides, the servants are longer than the airborne capsule, so they can't get into it at all, and it's useless to support them.

And what about landing craft?

There were a total of 90 landing craft on the three assault ships, and more than 80 were damaged, and each of them could hold a fully armed airborne platoon of about 30 people, which was replaced by tall servants...... Well, regardless of comfort, you can probably fit so much with a squeeze. If all of them were dispatched, a single wave could send more than 2,000 people to Europa, and it would take four and a half flights to empty a transport ship.

Continuing to count, it only takes thirty-six rounds to send all the servants on eight transports to Europa.

However, the account is not calculated like this, the landing craft can indeed take off from satellites with less gravity, but each liftoff needs to consume a lot of fuel, and the fuel reserve in the assault ship is not so much, and it can support three round-trips at most.

The three supply ships also brought some spare fuel, which could probably support another six round-trips.

In other words, if all the fuel is exhausted, you can send two servants, and you can barely send it all.

Ye Han didn't know how many aliens there were on Europa, but there must be more than three and a half million, and how many sounds could be heard in the more than 20,000 servants?

After thinking about it, a large-scale landing will have to rely on landing.

There is no hope of a full-scale air strike, and the only feasible way is to conduct a targeted air strike, clearing a safe landing ground first...... The effective range of fine light is 6 to 700 kilometers, and the range of concentrated fire is even farther, and in order to ensure safety, the radius of the landing field cannot be less than 800 kilometers.

Thinking of this, Ye Han couldn't help but smile bitterly, that is, clear the landing field and send the servant army up, if you want to expand the scope of control, you must first cross the 800-kilometer safety zone, what a special OO he is XX!
