Li Chen opened his system backpack, and immediately saw several special gift bags lying quietly inside.

[Super luxury gift package (advanced)]

After using it, you can get a variety of super luxurious rewards, including but not limited to energy crystal cores, evolutionary energy, technological equipment blueprints, production line blueprints, rare advanced potions, etc.

…

[Xinghai-class naval main fleet building spree]

The Xinghai-class battleship originated from the 1.9-level cosmic civilization. As the name suggests, it is a super battleship tailored for star navigation.

The battleship spree includes blueprints for building air-space carriers, air-space destroyers, air-space frigates, and air-space cruisers that integrate sea, land and air.

…

These two big gift packages are different from the rewards Li Chen received before.

If the grade quality is distinguished according to the color.

The rewards that Li Chen received before, such as super luxurious gift bags, were usually glittering in gold.

And this time I got these two big gift packages.

Their colors are colorful and gorgeous.

This should be the difference in quality...

In fact, you can tell just by looking at the description.

The super luxurious gift package, the rewards that can be opened are already very generous.

The advanced level super luxurious gift package, the reward is of course better.

But Li Chen had no choice.

Use the advanced super luxurious gift package directly.

The reason is also very simple.

This kind of dynamic reward gift package, the more rewards you get after using it, the richer and richer it will be!

At this time, Li Chen set his sights on the [Gift Package for the Main Fleet of the Xinghai-class Navy].

【Ding! Do you want to use the ‘Xinghai-class naval main fleet to build a spree’? 】

【Used successfully! Congratulations, you have obtained the blueprints of the aerospace carrier production line, aerospace destroyer production line, aerospace frigate production line, and aerospace cruiser production line... Please check them in the system backpack! 】

At the same time as Noah's reminder sounded, Li Chen's system backpack automatically popped up in front of him.

And the viewing angle is automatically locked to the corresponding production line drawing.

[Drawings for the Aircraft Carrier Production Line]

After use, it can be used to build the production line of the space carrier, which is used to manufacture the space carrier.

The space carrier is a technological product of the 1.9-level cosmic civilization, and it is one of the export-type equipment.

It is one of the series of star sea motherships belonging to the medium and large basic level.

The space carrier can carry out activities underwater, on land, in the air and in outer space.

It is mainly used to undertake combat missions in planetary sea, land, air, and outer space within a certain range.

A standard type of space carrier is about 1,800 meters in length and 450 meters in width, and uses the fifth-generation fusion reactor as the power source.

The power source can provide the space carrier with the power to continue sailing for more than three thousand years.

This type of space carrier can accommodate about a thousand integrated aerospace fighters of various types, reconnaissance/anti-submarine/anti-ship aircraft, electronic countermeasure aircraft, etc. at the same time.

…

Seeing the description on the construction blueprint in front of him, Li Chen was not calm at all.

"Sea, land, air, and space integration, four-dimensional warfare!"

"This f*cking space carrier is really badass!"

"A product of level 1.9 cosmic civilization! It really is amazing..."

Li Chen excitedly checked the descriptions of other production line drawings.

Aerospace Destroyer, Aerospace Frigate, Aerospace Cruiser, Aerospace Fighter...

All kinds of building drawings have similar descriptions.

These weapons and equipment are specially produced by alien civilizations.

Certainly not for their own use.

These are all used for export, equipment for lower civilizations to go to the stars!

In other words, these so-called medium and large-scale equipment in the air and space.

None of them are the active main equipment of level 1.9 cosmic civilization.

Instead, it is used for export and sold to low-level civilizations.

It is equivalent to those countries with powerful military and technology on the earth.

Equipment that you don't need, that have had their performance castrated, or even that have been eliminated.

"Export" to other relatively weak countries.

And charging the normal price, or even double the price, is almost the same.

But Li Chen didn't care about these things either.

Anyway, they are awesome.

It is enough to help Li Chen cope with the various crises and challenges that follow.

That's it!

As for more awesome equipment, that is something to consider in the future.

Thinking about it, Li Chen started to build these equipment production lines without hesitation.

And directly increase the production efficiency.

And it was at this time that Noah's prompt sounded in his mind.

[The host, which is close to the technological equipment of the second-level cosmic civilization, already belongs to the super-large energy response source body. 】

[You'd better control their number appropriately, otherwise once other alien civilizations notice the abnormality here, they may be attracted. 】

Noah's reminder made Li Chen slightly excited.

But Li Chen always had a doubt and wanted to ask.

Hearing that he was briefly stunned, he immediately asked.

"Noah, your statement is wrong!"

"Now the Star Destroyer mothership of the Prieters is watching in the sky."

"Isn't their super jumbo-class Star Destroyer Mothership carrying a bigger energy source?"

"If you have to say it, just their Star Destroyer Mothership far exceeds the energy radiation intensity of all our technological equipment combined?"

Li Chen asked this question after seeing the Star Destroyer.

In fact, I have already thought of it.

It's just that I never had the chance to ask Noah.

Hearing Li Chen's question at this time, Noah also gave an answer.

[Host, their Star Destroyer motherships have been strengthened. When operating or fighting, they will open up a powerful force field to surround the target planet. 】

[And block all energy radiation. 】

[In addition, even if some energy is radiated out, it doesn't matter. 】

[Because the universe is very large, and there are many, many high-level civilizations. Occasionally, a little bit of ultra-high-intensity energy radiation will not attract too much attention from alien civilizations. 】

[But the weapons and equipment of these advanced civilizations you have obtained so far do not have the effect of automatically hiding and isolating energy radiation. 】

[So if you systematically produce a large amount of equipment that exceeds level 1.5 civilization, you will be discovered immediately. 】

[The last one is that the Prieters are currently encircling and besieging the earth. 】

[They belong to level 3 cosmic civilization. 】

[Unless it is an alien civilization stronger than them, other alien civilizations will never intervene in the Pulitzer civilization to interfere with their offensive behavior on the earth. 】

[What they are more likely to do is to unite with the Pulitzer civilization to carve up the earth...]
