Asteroid belt, Thunder Mountain.

It was pitch black all around, and there were no celestial bodies in sight, no heaven or earth, only a smaller circle of the sun hanging in the distant sky.

Outside the battleship, dozens of people worked together to remove a ten-meter-square armor plate from the front cabin surface, and then held the heavy armor plate together, slowly moved to the middle of the battleship, and stopped above the last gap.

Ye Han let go and flew under the armor plate, and commanded loudly: "Down, down, down...... Posterior, posterior ...... A little further up, good! ”

The armor plates snapped into the gap, and a group of fighters immediately flew over and carefully fastened the seams between the armor plates.

The last piece of armor was installed in place, Ye Han let out a long breath, flew out of the battleship in a detour, and breathed a sigh of relief when he looked at the complete armor under his feet.

It's been a whole week, and the outer armor of the battleship has finally been repaired.

But when his gaze turned to the front cabin, Ye Han twitched a few times in his heart.

In order to repair the middle section and the rear compartment, not only all the intact armor plates of the front compartment were removed, but also a lot of damaged armor plates were removed, and the current front compartment is like a thatched hut after the passage of the hurricane, the skeleton and cabin are all exposed, and only a few broken plates are left to hang on it.

And every remaining armor plate has a worm machine nailed to it, and it looks tattered and in a mess, which is called a miserable and desolate.

Looking at the middle section and the rear compartment, everywhere is covered with heavy armor, although there are some gaps between some armor plates, but the armor is placed in a layered way, which has no protective effect on the enemy's firepower, but it is impossible for any rays from the outside to directly hit the inner layer, so as to ensure the safety of the inner layer.

At this moment, several different flavors were intertwined in Ye Han's heart, just like knocking over a five-flavor bottle, it was simply a mixed taste.

He couldn't help but sigh: "What is modularity, this is called modularity!" ”

This sentence is not said casually, because being able to repair the battleship so quickly not only benefits the all-out efforts of all the officers and men of the ship, but also has a direct relationship with the structure of the battleship.

Children have no mothers, it's a long story, from the very beginning, the human space battleship was born to fight aliens, in order to speed up the manufacturing speed of the warship, Beiyuezhou has adopted a modular design since level 011.

In other words, as long as all the parts required for the battleship are manufactured according to the standard, and then assembled together, it is a complete battleship.

Moreover, modularity is only one of the means to speed up the speed of shipbuilding, and another important means is a platform with a variety of configurations.

To put it simply, all the warships produced by Beiyuezhou use the same basic structure, this thing is like the skeleton of a battleship, and the orbital factory only needs to add cabins, armor and various weapons to the skeleton, it is a complete battleship!

In other words, although the Thunder Mountain is much more advanced than previous destroyers, its basic structure is not much different from previous warships, including the armor.

The armor of the Leishan is completely common to the armor of other capital ships, in order to do this, the military divides the armor into several types such as plane, curved surface and connection, each type of armor has exactly the same specifications, using the modular armor prepared in advance, it can quickly cover the surface of a battleship, at most a small number of armor plates of special specifications are used in the corners and corners.

However, the versatility of special specifications should also be considered, and the more battleships are built, the special specifications have become regular sizes.

It is precisely because of the modular base of the Leishan that the armor removed from the front cabin can be loaded into the middle and rear cabins without obstacles, and when it returns to Beiyuezhou in the future, as long as the front cabin is repaired and repaired, and then covered with a layer of armor plates, the Leishan will be able to recover immediately.

The armor has been repaired, but for the Leishan, this is only the first step in the long march.

At present, Leishan is still in the inner asteroid belt, and the distance from the Earth's orbit is not less than 1.5 astronomical units in a straight line.

This is nothing, and the problem that makes Ye Han scratch his head is that the battleship is not on the right course!

If the Thunder Mountain continues to fly on its current route, it will take at least three to five years to return to Earth, and in the event that all the thrusters fail, the most effective way to return home is to be rescued by friendly forces.

However, there are only a few human warships in the entire asteroid belt, and the friendly forces in the direction of Base 3 are too far away to quench their thirst; The distance between the Nanzhou and the Nanzhou was close enough, but after the Leishan broke away from the battle, the alien fleet refused to let go of the Leishan, and Gao Kai had to command the Nanzhou to entangle the enemy and buy time for the Leishan.

With the current situation, Ye Han only had two choices, one was to wait for the reinforcements sent by Beiyuezhou, and the other was to fly back to Beiyuezhou by himself.

It is simply unrealistic to wait for reinforcements, and it will take at least a month and a half to send a spaceship from Beiyuezhou to the reinforcements to get close to the Leishan.

A month and a half is not a long time, Ye Han can afford to wait, but no one dares to guarantee that the aliens will not trouble the Leishan during this time.

At present, the weapons on the Thunder Mountain are nine out of ten, let alone against the alien fleet, even an alien warship can't deal with it, it can be said to be completely disarmed.

If you can't count on rescue, you can only count on yourself.

After Ye Han returned to the bridge, he immediately summoned all the heads of the main departments and held a meeting.

The first meeting was to summarize the results of the previous stage, that is, to repair the outer armor with quality and quantity; The second is to deploy the next stage of specific work, that is, to repair the damaged thrusters.

Before the words were finished, except for Luo Qi and He Lu, who were in the know, the others were in an uproar.

It's not that everyone opposes the maintenance of the thruster, but that there is no precedent for field repair of the thruster at all, and if you want to repair it, you don't know where to start, how can everyone's reaction not be fierce?

However, Ye Han immediately said his plan, and everyone was relieved when they heard that it was only partially repaired.

"The first step in repairing is to find out the situation of the thrusters, and this matter is the same as repairing the armor, and I am in charge of it." Saying that, Ye Han rolled his eyes, "He Lu, you can introduce the situation of the thruster." ”

"Yes!" He Lu called up a document and said bluntly, "I haven't actually seen the thruster, according to the data analysis recorded by the tube loss system, the main problem of the thruster is the deformation of the reaction cavity caused by long-term overpower operation, and the other problems are all collateral problems caused by the deformation of the reaction cavity, and the specific situation must depend on the specific situation of the reaction cavity...... That's probably the case, Captain, I'm done. ”

Ye Han tugged at the corners of his mouth: "You are really simple enough...... Who still has questions? ”

Guys, you look at me, I look at you, no one spoke.

"No problem? So let's do it first. Ye Han said, "Everyone is very hard during this time, after going back, inform the soldiers to rest, when to repair the thrusters, etc., let's disperse." ”
