The marines were ready to land in the air, but the Yushan had no intention of moving, but the other warships accelerated to approach Europa, and the soldiers in the landing craft did not feel strange at all, and sat quietly in their positions and waited. Pen % fun % Pavilion www.biquge.info

The landing is not a matter that can be decided by touching the lips and patting the head, and the fleet must complete the necessary preparations before the departure of the troops.

Under the leadership of the Nanzhou, all the warships except the Yushan slowly moved forward, slowly approaching Europa, and releasing the carrier-based aircraft from a safe distance.

The fighter plane hovered near the battleship, ready to bomb the planet, and then Ling Yu gave the order, and the battleship and the fighter plane opened fire at the same time, and the lasers and shells pierced the void, piercing the atmosphere and falling to the surface of Europa.

The fleet first wiped out all the firepower points near the ice cave, and then radiated the firepower from the center of the ice cave, removing all the firepower points in sight.

There are many firepower points on the surface of Europa, some of which can be seen at a glance, and some of which are hidden under the ice, but it doesn't matter, the Expeditionary Force and the International Fleet have been recording the situation of Ganymede in previous battles, and they have already touched the firepower points on the surface of the planet, and the Third Fleet only needs to name them one by one according to the information.

Moreover, the front of Ganymede has long been scorched, and all the remaining firepower points are on the back of Ganymede, saving the fleet a lot of trouble.

There were also some suspected targets that looked like points of fire.

The fleet's movements were unusually smooth, and there was no resistance from the firepower points on the ground, this phenomenon attracted Ling Yu's attention, thinking of the whereabouts of the alien fleet, he couldn't help but say: "There is not even a building on the ground, the enemy must be hiding underground, let's bomb like this and not solve the problem at all." ”

"Voluntarily abandoning the ground? Hehe, aliens are quite generous! Wang Tianyu's tone was not good, "Commander, what do you say?" ”

"I don't know." Ling Yu shook his head.

It's fine if the aliens really give up on the ground, but on the other hand, if they deliberately retreat underground to lure humans to the hook, wouldn't the airborne landing fulfill the aliens' intentions?

Although there is no clear evidence at this time, from all indications, the alien lair must be located deep in the stratum of Europa, otherwise the alien fleet would not have been able to hide from the jets of the star engine...... The more he thought about it, the more he felt that aliens could attack the surface at any time.

Ling Yu's speculation does have some truth, but if Ye Han is here, he will definitely tell him that the alien battleship is not so simple, at least there is no problem with being a submarine part-time.

There is also the fact that alien warships are likely to grow on underwater vines, and this thing has been an amphibious since the day it was born, and the fleet must pay attention not only underground, but also underwater!

"Report!" Duan Jingwen's voice interrupted Ling Yu's thoughts.

"What's the matter?" Ling Yu asked unhappily.

"Commander, look here!" Duan Jingwen pointed to the screen and said.

On the screen is a magnified ice field of Io, where there is a charred black mark, clearly blown out by a cannonball, but the point is not that there is a large area of ice that has collapsed nearby!

The picture is not very clear, but you can see that there is an ice cave at the edge of the collapsed ice surface, and the arched ice cave is in a regular shape, and it is definitely not a natural formation.

Ling Yu immediately understood what Duan Jingwen meant: "This is ...... Alien lair? Is that why they love to drill holes? "The aliens who have landed on the earth are all burrowing in the ground, and the aliens on Europa are still drilling ice caves, could it be that the aliens have entered the cosmic age or are they cave creatures?

"Maybe it's safer underground." Wang Tianyu remembered the car bug, that thing is a good hand at making holes, which shows the preferences of aliens.

Ling Yu nodded, feeling that Wang Tianyu's speculation had some truth.

Although aliens have entered the age of space, the way to fly through interstellar space is not to drive warships, but to control planets!

Ling Yu had also attended training courses and made up for his astronomical knowledge, otherwise he would not have been the commander of the Third Fleet, and he could imagine the difficulties that Ganymede encountered in crossing interstellar space—moving away from the stars, the temperature gradually dropping, and even the air freezing to the surface of the planet, not to mention the long hours it would take to fly through interstellar space.

Before Callisto arrived in the solar system, it was impossible to imagine that it had been flying in cold interstellar space for hundreds or even thousands of years!

Think about it, how sturdy a ground building must be to withstand the erosion of time during a long journey? Besides, interstellar space is not really empty, and it may hit something one day.

Therefore, it is safest to move everyone underground and use the thick crust as a shield, and this method is the most economical, practical, and most in line with the technical level of aliens.

If you don't even have this level, I'm afraid that the aliens will all die before they reach the solar system.

Wang Tianyu said again: "Commander, don't you need to send a few people over......

Ling Yu didn't answer and asked: "Are there many similar situations?" ”

"Not much, there are three places collapsed now, but I think these holes under the ground are eighty percent of alien communication trenches, as long as it is a firepower point, there is this thing underneath...... Why don't you try to keep an eye on a fire point? ”

"Give it a try!" Ling Yu said.

Wang Tianyu immediately conveyed the order, Duan Jingwen personally picked a firepower point, and the Nanzhou specially vacated a naval gun to do this, and fired more than 20 shells in a row, at least half of which accurately hit the firepower point, but there was no intention of collapsing at all.

Wang Tianyu frowned: "Change places and pick the firepower points on the ice field!" ”

The earth's crust is relatively strong, and the ice crust is much more brittle than the earth's crust.

Duan Jingwen immediately executed it, and changed to a firepower point close to the ice cave that had been destroyed by the fleet.

This time the effect was quickly seen, and before ten shells were fired, there had already been a collapse, but the collapse was not serious, the section was relatively hidden, and the passage mouth could not be seen.

Wang Tianyu cast his gaze on Ling Yu: "Commander? ”

"Inform Ye Han of those holes and ask him to send someone over to take a look...... Also, the mission goal of the Marine Corps is the planetary engine, just look at those few holes, there is no need to risk it. ”

Wang Tianyu said: "I understand, I will tell him personally." ”

The communication was quickly connected, and Wang Tianyu explained the situation again, emphasizing safety, and then interrupted the communication.

Liu Bin, who was listening, couldn't help but ask, "Boss, what does this mean?" ”

"It's literal." Ye Han said without hesitation.

He didn't care what Wang Tianyu was implying in the literal sense, in short, it was no problem in the literal sense.

"Then I'll bring someone there." Liu Bin took the initiative to ask.

"No, you don't." Ye Han shook his head, "You take someone to find the engine, and I'll take someone to check the ice cave." ”

Liu Bin grinned and didn't insist anymore: "That's okay, I've left a psychological shadow, and now when I hear about drilling holes, my heart is furious!" ”
