The generals' faces became serious, and the information Zhang Binhui brought back made them feel even more powerful pressure.

"Don't worry, although Europa's environment is more conducive to aliens, occupying Europa has a great advantage for us, and that is its gentle terrain."

Seeing everyone's serious gazes, Zhang Binhui smiled: "The second battle will be the most magnificent landing operation in the history of mankind in the solar system, and this time, the geographical advantage is on our side." ”

Speaking of which, Zhang Binhui cleared all the atmospheric environment in Europa's map, and the terrain there was presented in front of everyone.

"The Alliance has long had Europa's clearest terrain data, which is the biggest advantage of our landing operations.

Europa's surface is quite smooth, as it is largely covered by ice, and it rarely has undulations of more than a few hundred meters.

According to intelligence, Europa is the smoothest object in the solar system. Its 'surface' will only show rippled undulations under the impact of huge tides for a long time, and its terrain is unobstructed, which is very suitable for large-scale armored operations.

Not only that, but due to Jupiter's huge weight, most of the meteorites fell on Jupiter, so there are very few impact craters on Europa, which is the real reason why Europa is the moon with the highest regisation.

In the second battle, our mecha troops and earthlings' tank troops will carry out beach landings, and the firepower of science and technology will sweep all aliens on the ice, and the advantage of the second battle will be on our side. ”

A smile appeared on Yan Chengjian's face, the prince of the Great Western Kingdom, the future emperor of the empire, he was a top mecha master, with extremely rich experience in swarm mecha combat.

With good vision and excellent terrain, Yan Chengjian is confident that he can defeat the alien on the ground.

"After consolidating Europa's surface positions, the third battle will begin, and it will be the most difficult."

Zhang Binhui clicked on Europa's topographic structure map and began to introduce his third-step battle plan:

"Xenomorphs love to stay underground, and if we want to get rid of them completely, we have to fight 'underground', so we have to go down to the bottom of the ocean.

There are two ways to get from the ice to Europa's bottom of the ocean, one is the ice cressure I mentioned earlier, which will be the main passage for our troops.

The fissures provide us with tens of kilometers wide of the ocean, from which our mobile forces can descend to the bottom of the sea, but here we must pay close attention to the greatest hazard, which is the huge tides of up to a hundred kilometers on Europa.

The second is the ice volcano on Europa, which is unique to Europa.

Contrary to Europa, Europa also has volcanoes, but it is an ice volcano that spews out ice cubes that mix with seawater to form ice fountains.

These volcanoes are capable of spewing spectacular fountains up to 200 kilometers high, which usually erupt intermittently for about seven hours.

Don't worry, the fountain can be timed, it will appear when Europa is furthest from Jupiter and disappear when it is closest to Jupiter, also because of Jupiter's tidal gravitational pull on Europa.

It causes cracks in the ice on Europa's surface at its farthest point, from which fountains erupt and gradually close when Jupiter's closest point is reached.

This is a similar situation to those cracks tens of kilometers wide, the same result of Europa's ice crust being 'breached' by the inner ocean.

The rift will also shrink, but it will not close completely, and these fountains, on the contrary, they are much narrower in width, so the appearance of the fountain is uncertain, but it will create another raid passage for us.

Here, I would like to emphasize one sentence: large forces can only enter through cracks, while raiding troops can take advantage of these fountains.

The fountain on Europa is a high-pressure water vapor and broken ice that escapes from a very narrow chasm, and because of Europa's strong gravity, what is spewed out does not escape into space, but instead falls back to Europa's surface when it erupts to an altitude of 201 km.

The intensity of the impact there is so great that raids are normally carried out by our Alliance team. ”

With the raging tides and violent fountains, it is clear that the location is once again on the side of the aliens.

Zhang Binhui went on to explain: "To enter Europa's oceanic interior, we need to build an undersea base and then start underground operations.

Europa's main body is similar to that of terrestrial planets, i.e., it is mostly composed of silicate rocks.

Europa's magnetic field is capable of generating an induced magnetic field on its own, and beneath its thick layers of ice and seawater is a circle of rocks. And in its deepest part, there is a metallic iron core. ”

Speaking of this, Zhang Binhui called up a series of weapons and equipment: "This is the ground-penetrating combat equipment supported by the alliance, and your special operations brigade has adapted to its operation, which is the most advanced weapon in the scientific and technological planet in our human alliance."

The Lava Tank, which is actually a battle mech, has beams of high-energy particles that break down nearby rocks, causing them to enter a lava-like granular state, allowing them to burrow into the ground with ease.

It has two main guns, one on the left arm and one on the shoulder, firing high-frequency particle beams.

However, due to the influence of the density of the medium, our human technology is far more affected underground than the alien, so its main weapon, the high-frequency impact stinger, is the real killer of the lava tank.

Our special operations brigade must follow the rules of the battlefield, that is, to strive for numerical superiority, we must use three lava tanks as a group to form an advantage over aliens.

I believe that after space battles, surface battles, and ocean base construction battles, the number of aliens on Europa will not be too many, and we will be able to have a numerical advantage over aliens.

But we also need to note that the last aliens in the underground are definitely their most powerful presence on Europa, so the battle will be more difficult at this time.

Crucially, each of you must remember the core mission on the battlefield mount, which is to kill the alien female worm on Europa. ”

Speaking of this, Zhang Binhui's voice became serious: "After a variety of data analysis, the alliance has been quite sure: the alien has a female worm on Europa.

In addition to the temperature, the atmosphere and moisture here have created excellent conditions for the reproduction of aliens, and there is no reason why they should not place their mothers here.

It's been a while since the Xenomorphs arrived in the solar system, and the data from the last Ganymede battle has been transmitted back, and based on the support forces from Europa at the time, the Alliance believes that there is a female worm on it.

Killing the mother worm on Europa is the final mission of our campaign. ”
