He Lu rolled his eyes: "You're almost there, have you forgotten, aliens' brains are like hard drives, they can write things directly into their heads, in case they write the technology that has been passed down from the past directly into their brains, what do you say is the result." ”

Luo Qi couldn't help but be stunned when he heard it, and had the heart to refute it, but in the end he had to agree with He Lu's hypothesis, because aliens do have this technology, if there is really any ancient technology that has been preserved to this day, it is much easier to recover than humans.

Luo Qi was silent for a moment, and suddenly thought of the omission in He Lu's words: "No, no, no, it's not like this, if they could really do it, they would have occupied Mars a long time ago, and they wouldn't have been able to wait for today, how long has it been, they first occupied Jupiter and then drilled the asteroid belt, but they didn't have the idea of Mars, doesn't this explain the problem?" ”

This statement immediately won everyone's approval.

For aliens, Mars is a barren land, but for humans it is different, aliens must know that humans have the ability to use Martian resources, and they know that once Mars falls into the hands of humans, it will become a bridgehead for humans to enter the asteroid belt, which is not good news for aliens who are bent on occupying the earth.

To put it more simply and bluntly, that is, Mars belongs to a long-term vision, steady and steady; Crossing Mars is a strategic adventure for quick success.

It is true that extraterrestrial civilizations are different from humans, but that doesn't mean that aliens don't have a strategic vision...... Well, the adventurous wave of aliens is now on Earth, and those who don't like to take risks are approaching Earth step by step.

Thinking of this, Ye Han said: "Okay, don't fight, we know too little about things, it's not interesting to fight for these, what should we do."

This is the end of the debate, and everyone continues to focus on the situation on Mars.

The aliens were not in a hurry to attack, and the defenders were not in a hurry, taking advantage of some time, the defenders seized the time to adjust the fleet, and the transports that were too late to be withdrawn, the transports that could not be withdrawn, and the orbital elevators all flew to Phobos, where the super cannons had already been completed and could provide protection for these auxiliary warships, which was the best anchorage and safe haven.

Since only the super cannon was built on Phobos, and other auxiliary facilities had not yet had time to be constructed, the battleships that were withdrawn there could only fall into the craters on the surface of Phobos, and then cover them with camouflage nets and other things.

Although the method is a little dirty, the effect is still very good, even if the warships of the human family are not carefully searched, they can hide the past, and it is not a big problem to hide the enemy.

You have to be careful when burying it, the gravitational force of Phobos is too low, and if you use a little more force, the dirt and rocks that are lifted up can fly away from Phobos.

Because there are too many transport ships, and there is such a big guy as a rail elevator, in the end there are not enough craters, and the extra transport ships can only be parked on the surface of Phobos.

As for Deimos, there is no need to mention it, no one wants to go at all.

There are also super cannons on Phobos, which can also protect transport ships, but the problem is that Phobos is small in size, and there are not so many places to place transport ships, and the orbital altitude of Phobos is more than 23,000 kilometers, which is really far away - the super cannons placed on Mars and its satellites are of low grade, the number of lasers is not enough, and the maximum range is only 25,000 kilometers, which barely includes Phobos in the range.

To put it simply, it is the three super cannons on Mars and Phobos, as well as the Martian defenders who can cover each other, but Phobos is alone, and the division of troops will dilute the strength of the defenders, and the artillery cover is also a little inadequate, so the defenders think that the aliens are likely to use Phobos to open the way to Mars from here.

To this end, the defenders tried their best to strengthen the strength of Phobos, and set up a large number of missile positions on Phobos, hoping that these missiles would allow Phobos to hold out for a while.

Two days later, a second group of enemy ships arrived on Mars, along with dozens of asteroids.

The alien fleet immediately launched an offensive and threw the asteroid towards Mars, and the asteroid was thrown at a very tricky angle, perfectly avoiding the firing range of the super cannon.

In order to avoid the super cannon, the aliens hollowed out their minds and made a long observation in advance, not only determining the location of the artillery array, but also using the experience gained on Ceres, to calculate the firing range of the four artillery arrays.

That's not all, they also took into account the location of the two moons, and deliberately waited for Phobos to move to the other side of Mars.

As we all know, the angle of rotation of the laser launcher determines the firing range of the super cannon, and the two artillery arrays on Mars are located at the north and south poles respectively, controlling 68% of the Martian sky.

The artillery array on Phobos can also control a part of the sky, but the specific areas to control must depend on where Phobos runs.

The same is true for Phobos, since the positions of these two satellites are not fixed, the control range of the artillery array is not fixed, and it is not difficult for the aliens to avoid the super cannon as long as they find the right direction.

If all the artillery arrays are placed on Mars and the positions are reasonably distributed, the four artillery arrays can absolutely control the Martian sky 100%, the problem is that Mars is never a good baby, but is known for its short temper, almost every year at the turn of spring and summer, this grumpy red planet will have a large-scale dust storm, covering half of the planet dust storms are not uncommon at all.

The average duration of a Martian dust storm is a few weeks, but there are many longer ones, with the largest Martian dust storm on record occurring in 1971 and lasting several months from late September to late December.

In October, the most severe month, all but the bright region of the polar crown of Mars was covered in dust storms, which lasted for so long and covered a wide range that it was simply appalling.

Compared to Mars, the sandstorms on Earth are simply weak.

Of course, global dust storms are not so common, but regional dust storms are commonplace.

On the contrary, if the artillery array is placed in another place, once a dust storm occurs, the floating dust raised by the wind will float to a height of several thousand meters in the air, completely submerging the artillery array under the dust, even if the artillery array can determine the target direction through satellites, the beam will be greatly weakened by the dust in the sky.

It is precisely because of these restrictions that the joint command has to place two artillery emplacements at the poles and the other two artillery emplacements on satellites.

Designers and builders have mentioned more than once that Mars is not a suitable place for supercannons, but rather that the atmosphereless environment of Ceres, Ceres and satellites, is more suitable for artillery arrays.

The placement of the artillery array had to accommodate the environment, leaving a lot of flaws, and now this flaw has been discovered by aliens, so they directly take the asteroid and smash it on Mars.
