> more large reconnaissance "dark eyes" are released, people need to know what is happening outside the asteroid ring early.

At the same time, the expeditionary force formulated a plan to clean up the asteroid ring, and according to the research of the staff committee, the Great Western Kingdom planned to build this asteroid ring as a barrier, first of all, to ensure that the aliens could not pass through here.

"Alright brothers, we have work to do again!"

Happily holding the warrant of the headquarters, Ma Tianyuan and He Qiliao rushed out of the commander's room, and then shouted at the mechanics outside:

"Fleet command order: The 16th cabin mechanic battalion has completed the mine installation task of the A19 bid section, and we are going to leave the cabin!"

The cheers suddenly shook the cabin, and all the mechanics from the earth jumped up with joy.

This is an out-of-cabin operation! Something never thought about. On Earth, watching those astronauts spacewalk, these soldiers don't know how envious they are, and they can't imagine that such a good thing will soon be their turn, and it makes people excited to listen to it.

"Cough", Ma Tianyuan coughed: "Don't be so happy so quickly, not everyone has it, at least half of them must be left, and the equipment maintenance task here is still inseparable from us."

I will draw 80 fighters, and explain in advance that you will not have a chance to walk in space, and your task is mainly to pilot the spaceship and cooperate with me and Vice Captain He. ”

It's okay to drive a spaceship, the mechanic battalion is equipped with engineering ships, and these soldiers have been itching for a long time, so they stared at the two captains again.

With a "poof", the lift-off passage was depressurized, and the crab-shaped engineering spaceship sailed out of the mothership.

The pilot of the spacecraft is called Wang Tiezhu, Wang Erdan's brother, and he was brought over by Ma Tianyuan.

After coming into contact with this unit, Wang Tiezhu finally knew the reason for his brother's sacrifice, and then he also saw the video, and immediately felt as if he had come to another world.

Wang Tiezhu applied for the training index of Daxiguo, and then followed him all the way here. Huo Ran looked back and suddenly felt like a dream, Wang Tiezhu never imagined that he would be able to pilot a spaceship one day, and even have the opportunity to lay mines to avenge his brother.

Meteorites and stars flowed past the side of the spacecraft, and Lot A19 was not far from the mothership, and the lights of the mothership could still be seen from behind.

In the cockpit, countless red lines automatically connected to the flying meteorite, which was the spacecraft's automatic rangefinder calculating the danger of the meteorite, and soon, the spacecraft had sailed to its destination.

"Start the landing process." Wang Tiezhu shouted out the operating procedures and began to control the spacecraft to land.

The target is a larger meteorite, and the ship will be anchored on top of it, which will better avoid the impact of other rocks.

Through the auxiliary observation system, combined with the ship's automatic landing device, the stars below the hull are getting closer and closer.

"Release the crab anchor." With Wang Tiezhu's command, the four huge mechanical legs of the spaceship stretched out.

With a "poof", the tip of the mechanical leg snapped into the rock, and the thick joint snapped over.

With the sound of suspension and decompression, the spacecraft landed steadily on the asteroid.

"Beautiful!"

He Qiliao praised him, and then got into the engineering mecha with Ma Tianyuan.

The hatch overhead closed, and the platform began to descend toward the planet's surface. On the lifting platform, in addition to He and Ma, there is also a small automatic spacecraft, which is both a robot and a mine transporter, which will cooperate with the two to complete the task of installing mines.

With a few "poof, poof" sounds, accompanied by a faint dust rising up, the mecha and the small spaceship sailed onto the ground of the planet, and the two of them will first complete the task of installing mines on this planet.

A little light flashed from the far star ring, and Ma Tianyuan and He Qiliao knew that it was the expeditionary force's troops clearing the aliens in the asteroid belt, and they would provide a safe environment for the various mechanic teams to forge this Great Wall of space.

With a slight jump, the mecha soared into the air, and the two jumped forward.

The mecha of the Great Western Kingdom was very advanced, and it had already automatically adjusted the gravity settings, so Ma Tianyuan and He Qiliao didn't feel any difficulties in operation, and they quickly arrived at the target installation site.

The two of them lowered the shoulder cannon, and it was only at this time that they really knew that this shoulder cannon, which was majestic on the earth, was only used by the Martians for cutting, and its power was not as powerful as that of the battle mech.

With a "buzz, buzz" sound, the astral rock began to melt, and the shoulder cannon easily cut a block into the ground.

The two engineering mechs pierced their hands at the same time, and with a "poof", four metal claws snapped into the rock block.

"One, two, three, lift!"

With Ma Tianyuan's command, the four mechanical arms exerted force at the same time, and the rock made a "click" cracking sound, and then saw the two mecha thrown out, and the stone weighing more than ten tons was thrown into space by them.

The small ship flew above the crater, its bilge opened, and a quadrangular device similar to the shape of the crater was buried.

Ma Tianyuan activated the mine, and the bottom of the pit made a "poof, poof" sound, and the mine fixed itself in the hole.

"That's it, let's move on to the next goal."

The two mechs landed on top of the small ship, and the ship flew towards the next star.

On the other side of the asteroid belt, space mechs fly between meteorites, followed by the camp of battleships.

Dense firepower blasted into the starry sky, and a large number of stars volleyed into powder, and the resistance of the aliens was difficult to achieve.

As expected by Command, the pest control team found more aliens, but they were mostly hidden in meteorite clusters in a sporadic state.

These bugs are supposed to be alien space expansion troops, and their main duty is to scout the appropriate expansion space for aliens.

This also shows a problem, which is exactly what everyone is worried about - the original breeding space of the alien is already full, and the alien has bred enough bugs, and they need a wider environment.

A month later, the asteroid belt was largely cleared, and even if there was any leftover, it would have no effect.

During this period, there were no aliens outside the planetary rings to help the star rings, and the expeditionary force completed all the operations in an orderly manner, and everyone's eyes fell on Ganymede.

Ganymede, a moon orbiting Jupiter, orbits in about 7 days. Sorted by distance from Jupiter from near to far, Europa is seventh among all Jupiter's moons and third among Galileo's moons.

It maintains a 1:2:4 orbital resonance relationship with Europa and Europa. Ganymede is the largest moon in the solar system. Its diameter is even larger than that of Mercury, with a mass of about half that of Mercury.
