The asteroid was hollowed out and converted into a huge military base, with everything a military base should have, and it was also a complete and independent base, with its own research department.

The space inside the base is large and has perfect armed measures, it is a space fortress that belongs to the freedom of the Fourth Fleet, and it is also the real garrison base of the Fourth Fleet, as for the moon base, it is more like a comprehensive port under normal conditions, but there is only the First Fleet stationed.

This base reminded Qin Yun of the Solomon Fortress in the Gundam, although the shape is different and the color is different, but it is generally the same thing.

However, Qin Yun didn't know what the internal structure of Fortress Solomon looked like, but the inside of the Fourth Fleet base was a circular structure with the Central Spaceport as the central axis, and there was normal gravity in the entire base except for some areas, as for what kind of means and technology Qin Yun came to this point, it was not clear.

Since he was transferred to the technical unit, Qin Yun's clothes have changed into sky blue coveralls, and he can basically only stay in the technical department every day to cooperate with the compilation of the OS, and then cooperate with the technical department to test the backpack, and there is no chance to enter the bridge.

Qin Yun himself felt that it was of course best to be able to intern and perform his duties on the battleship, but for others, of course, this other person was more referring to the senior management of the Fourth Fleet, and it was more useful to use Qin Yun's ability in the development of new equipment.

There is no shortage of excellent captains, but people who can compare with a department in writing OS, and who can provide better development ideas and tests for new equipment, are much more important than a captain.

And after coming to the base, Qin Yun also communicated with Nikolai's entire department about the idea and design of the backpack, and put forward some opinions for the completion of the backpack, and then the technical department rushed to produce two versions of the new backpack in a dozen days.

The first version is equivalent to an upgraded version of the previous backpack, no longer the previous shape that looks roughly like a block, but has become a combination of the main structure and the lower structure, which looks more like a jetpack than a block.

The main structure is the backbone of the whole backpack, the upper structure is two separate sets of integral thrusters plus a pair of foldable flying wings, and the lower part of the structure is two sets of thrusters that can greatly adjust the angle and a pair of adjustable small flying wings.

In terms of weapons, the waist cannon was canceled and only two beam sabers were retained, the weapon interface and two beam cannons were retained, and the main structure part has two mechanical arms that can be mounted and used for weapons, which is a fully optimized version of the previous backpack, and even the shape has been completely optimized, at least it looks like it really has one more flying part instead of a school bag on its back.

The second type is a little more complicated, it can be regarded as an upgraded version of the high-speed fully armed backpack, and it is also a thing specially made for Qin Yun to test.

Let's talk about armament first, two high-energy beam guns, two high-speed beam guns, two electromagnetic waist guns, two Grimm machine guns, two ship-chopping knives that Qin Yun strongly demanded, two high-energy beam sabers, and built-in small eight missile launch tubes.

In terms of optional weapon configuration, you can choose two standard beam rifles based on the body, but through this incident, Qin Yun also heard from the people in the technical department that there are already other departments developing new beam rifles, but the specific situation even Qin Yun, who is in the technical department, has not been able to know.

If the first backpack can also be used in the atmosphere to obtain better air and flight performance than ordinary sky-type rays, then the second backpack is absolutely impossible to use in the atmosphere, and even if it can be used in front of it, it will only become a burden for the body and pilot.

The backpack has reverted back to a one-piece structure, and is thicker and larger, with six sets of main thrusters and eight thruster ports, and a large lump after being equipped on the fuselage, and adjustable flying wings are placed on both sides of the backpack in an X-shape.

The two choppers were not folded, and it is said that due to material problems, they eventually shrunk and hung under the fuselage and extended backwards, looking like two tail fins suspended below.

The two high-energy beam guns above the backpack have the ability to adjust at a large angle, and the two high-speed beam guns are integrated on the backpack, which just sandwiches the head of the body in the middle when the backpack and the body are combined, and only has the ability to adjust the angle of a small range, and the attack performance is one-third lower than that of the standard rifle, but the attack performance is reduced by one-third but the attack speed is doubled.

The waist cannon is also integrated into the backpack, it looks like two muzzles are clamped between the waist of the body, and the attack range is 30 degrees up and down, 25 degrees left and right, there is no gun body, only the muzzle This is because the gun body has been integrated into the backpack.

The Grimm cannon is also something that Qin Yun strongly requested to exist on the Hurricane before, although this thing is not necessarily easy to use against the enemy, but it also depends on people, but after correcting the OS, it can often get miraculous results against missiles, and it can also have a good effect on close-range attacks.

And these two Grimm cannons are completely installed on the mechanical arms on the left and right sides above the backpack, and they have learned the lessons of the last battle with the iron ball, this time Qin Yun did not forget about the shield, and the shield was reversely attached to the Grimm cannon, which made this backpack have two more shields.

At the same time, through the adjustment of the mechanical arm to defend the front and side, the most important thing is that this shield cannot be removed and there is a set of standard thrusters under the shield, from a certain point of view, this integrated Grimm cannon, shield cannon, thruster thing can be said to be a special combination of parts, and can be used as a balance wing and auxiliary thruster for backpacks.

This backpack is definitely an over-spec thing, in addition to not being able to act independently from the body, it has basically reached the limit that can be done in a short period of time, fully meeting all Qin Yun's needs for backpacks.

And the appearance of this backpack was originally unnecessary, because this is not something that normal people can use at all, and at the time of its manufacture, the entire technical department's evaluation of this backpack is that only monsters can control beasts, and the backpack has become larger, the energy size can also become larger, and the number of thruster groups is more correct, so that the speed has become faster, and it has reached four times the speed of the original radiant type.

It is worth mentioning that the normal performance of the first backpack after adjustment and optimization is twice the speed, and it can only reach three times the speed in the state of complete limit, and the whole process can be three times faster...... It's really not something that ordinary pilots can control, and if the speed is fast and the reaction is not enough, it is in vain.

Ordinary pilots can't do it, Qin Yun can know the condition of the body at any time, and then instantly adjust the output of the body to achieve the stable effect of the backpack, considering the direction of mass production, or need to consider more about the problem of versatility, safety, stability, operability are all areas that need to be considered, otherwise no one can use it after manufacturing, isn't it a waste of resources?

But the technical department also made it in order to collect more information, and it was also trial-produced in order to test the limit of what a backpack can do, and to change the limit of the body, because the current technical department is another monster that can't be measured by common sense.

After the two backpacks were manufactured, Qin Yun also conducted many tests, and Qin Yun was the only one in the first few days, but then Qin Yun didn't board the body to go out for testing, but sat behind the computer and watched the report to adjust the OS.

Because there is nothing else to do with the test, Qin Yun's test data cannot be used as a reference value at all, just to confirm the practicability, operation data, stability and so on of the ordinary backpack of type 1 and type 2 of the fully armed backpack, at most, it is to reconfirm Qin Yun's monster behavior, and even the unreasonable fully armed backpack of type 2 can be used flexibly.

However, this company has been tested for many days, and many people in the Fourth Fleet base already know that there is an extra monster in the experimental unit of the technical department, a monster that can operate mecha at more than three times the usual speed to fight, but few people will know what this monster really looks like.

On this day, Qin Yun sat alone in front of the computer and quickly tapped the keyboard with both hands without any thought, the crackling sound was connected into a string, and a bunch of people in military uniforms or work clothes stood behind Qin Yun, staring at the screen in front of Qin Yun with glowing eyes, and he rarely even blinked his eyes, for fear of missing any important data.

It wasn't until Qin Yun finally knocked enter to make the system in the computer start to self-test and simulate the operation that Qin Yun raised his hand and was about to pick up the cup on the table and take a sip of water.

But as soon as Qin Yun stretched out his hand, he was standing on the side, almost in his thirties, with a beard and hair a little messy, and a pair of glasses, so he handed the cup to Qin Yun with both hands, and said respectfully with admiration: "Big guy, please drink tea." ”

Qin Yun glanced at the other party's shoulder, which was one level higher than his own, and was silent for a while, took the cup, put it to his lips, and took a sip.

After putting down the cup, Qin Yun said helplessly: "Major Wu, you are the chief." ”

Major Wu hurriedly shook his head: "No, no, no, my technical major is not important at all in front of you, the big guy, are you right?" ”

"Cut, isn't it just that the technology is better, I came in a few years earlier than me, otherwise I would also be a major."

"That's right, he's an old man who doesn't like cleanliness, a single dog in his thirties, and the big guy will definitely become his chief immediately as long as he is willing to join our OS department with your skills."

Major Wu turned his head to look at his team members and shouted with an unhappy face: "Bastard, how can a girlfriend have a computer for fun." ”

Qin Yun: "............"
