The wormhole of the solar system is like Huarong Dao, such a small path can only barely support the development of galaxies and the huge communication needs with other galaxies within the civilization in the future.

If someone mutinies or an enemy attack, then it is easy to have the embarrassing situation of blocking a galaxy with a small number of warships.

Similar to the situation in the Age of Discovery, how to ensure the smooth passage between the colony and the central system is an important measure of the value of the colony!

Poor traffic conditions are also one of the reasons why the development of the solar system is a low priority.

At this moment, because the wormhole in the solar system was blocked by two "rebels", the pioneer legion in Proxima Centauri was not ready for the wormhole attack and defense, so it could only temporarily give up the plan to break into the solar system for reconnaissance.

"Report it to the public, we'...... Wait for the decision of the council! Ishar finally said.

Gustav had no position to object at the moment, so he had no choice but to acquiesce in this decision, but in his heart he hated Alsace, the source of everything.

It's all that scourge, why didn't he die in the solar system!

……

"Ahh Nie Yun commanded the two warships to complete a hanging blow to the Gemini reconnaissance ship, and when his consciousness switched back to his body, he sneezed violently.

"Strange, who's scolding me? Obviously let go of a ...... It is said that if you are a person and leave a line, you will see each other in the future, and people with a bottom line like me should be very popular, right? Nie Yun dissected himself and felt good......

That's right, that reconnaissance ship was deliberately let go by Nie Yun, the purpose was to paint the black cauldron of the Sea Clan with another layer of black paint, I believe that when the news reaches the Gemini, the Sea Clan's fun will be even greater.

In fact, Gustav was already in the middle of nowhere.

Nie Yun observed through the radar on the battleship that the wounded reconnaissance ship was returning to the interior of the galaxy, and the Gemini Pioneer Corps in Proxima Centauri did not show any signs of abnormal movement.

After observing for a long time, Nie Yun finally confirmed that the Gemini civilization did not intend to immediately carry out a more aggressive wormhole invasion operation.

"Very cautious! But...... Time has always been on our side! Nie Yun smiled.

……

Near the wormhole of the solar system, two warships defined as "rebels" each sent hundreds of silver shuttles to clean up the battlefield and devour the wreckage of the reconnaissance ships on the battlefield after destroying two reconnaissance ships from Proxima Centauri.

For the "super foodie race" mechanical bugs, every defeat of the mechanical enemy is an enhancement of itself.

It's like killing monsters to gain experience, the stronger the enemy, the more obvious the strengthening of yourself!

After the wreckage recovery work was completed, the two warships adjusted their attitudes slightly, and at the same time shot a traction beam that shone directly on a wandering asteroid about 10 kilometers in diameter tens of millions of kilometers away.

This wandering asteroid has been found to be extremely massive by gravitational radar, and it is preliminarily judged that it probably has a metal core that accounts for more than 50%, making it an excellent material for making floating defense fortresses!

The towing beam is used as an auxiliary acceleration device for long-distance interstellar travel on a battleship, and can also be used as a towing rope to tow a large mass target.

The battleship's engine spewed slightly, counteracting the huge reaction force.

The wandering asteroid was pulled by two beams of light, slowly changing its orbit and gradually approaching the wormhole......

At the same time, "Whoosh! "A large number of silver shuttles were ejected from the battleship, flew towards the asteroid at great speed, and plunged headlong into the asteroid's hard tundra after getting closer......

"Boom ......" ice chips splashed, and this very innocent wandering asteroid was instantly pierced into a hedgehog!

Wandering asteroid: "......" (#)

I'm a wandering asteroid, I didn't recruit anyone, I didn't mess with anyone, and I didn't think about a meteorite hitting the earth, but why? Why me?

I know I'm a little overweight, but being fat, is it also the original sin?!

"Chubby Paper" senses a deep malice from the world......

……

After a large number of mechanical insects landed on the asteroid in the way of "ten thousand arrows", they began to liquefy, and then immediately began to level the land, and built small robot production lines and supporting facilities with local materials.

About 10 hours later, when the asteroid was delivered to a predetermined location near the wormhole, three robotic production lines built from common materials and their accompanying resource gathering, metal smelting, and energy centers had taken shape.

A large number of mechanical bugs retreated to the mothership, leaving behind 10,000 small robots before leaving.

The robot production line and various facilities on the asteroid began to hum slightly, the indicator lights lit up one after another, and the rows of robots opened their eyes......

With the abundant energy infusion, the entire initial base instantly came to life and began to be noisy.

"The 12th Engineer Regiment, assemble here at once!"

"The resource collection team, hurry up and make the robot production line move, the construction period is very tight, we need more manpower to settle in!"

"From the General Staff Headquarters of the Earth Defense Force, immediately observe the terrain ......"

"Geological exploration team, collect data as soon as possible and send it to the Fortress Design Department of the Affiliated Academy of Sciences!"

“……”

A large amount of invisible communication fills this starry sky, the footsteps of civilization......

After more than two months, the Earth Defense Force has accumulated a lot of experience in the construction of the solar system defense chain, and is already familiar with the entire process of fortress construction.

As long as Nie Yun provided such a basic robot barracks, the rest of Nie Yun chose to be fully managed, entrusting the task of designing and building the fortress to the garrison of the Earth Defense Force!

Of course, advanced weapons such as shields and cannons still need to be provided by Nie Yun, and for the time being, the Earth Defense Force can only obtain various weapon parameters of related weapons, and they are red-eyed in envy and jealousy thinking about how to arrange these weapons......

However, professional is professional after all, Nie Yun, who has observed the construction of the solar system's defense chain, has to admit that in the field of weapon use, these professional soldiers have a keen sense of battlefield smell and more advanced design concepts, and the half-hung Nie Yun has drawn a lot of inspiration from the military defense system.

Robotic insects gain advanced technology by devouring copies, and Nie Yun learns advanced concepts and ways to use them!

Humanity is being guided and silently contributing its ingenuity!

"Is there a wormhole? Supposedly connected to Proxima Centauri? ”

On the edge of the construction site, three small, laid-back, somewhat out of place robots were talking to the distant starry sky in the direction of the wormhole.

Someone saw that these three robots actually looked like they were pointing at the country, and the higher military rank just wanted to go over and scold, but when they saw the title of "general" above the heads of the three people, they immediately continued their work without squinting.

Different from the various military rank systems of various countries, the Earth Defense Force has just been established and has not experienced many wars, so it is not common for military rank promotion, and the rank of general, there are only three people in the defense force so far!

"Hmmm! I really didn't expect that there was such a passage in the universe, and our earth had not even noticed it all along! Yuri, one of the three generals, sighed.

This is a deadly secret passage, and if it weren't for the Ghost Captain sharing the information they have obtained, they probably wouldn't even know where the enemy came from!

"Doesn't seem to be out of the ordinary? All sorts of detection devices did not react, and there really was a channel there? Schneider wondered.

Although this fortress is close to the wormhole, this "proximity" is only a distance of millions of kilometers relative to the range of weapons, and it is naturally out of reach for the observation equipment of small robots!

"Captain Ghost's intelligence has never been wrong!" General Hu said, and then looked at the starry sky in the distance, his eyes were a little yearning. "According to Captain Ghost, there are no noticeable changes in optics or force fields near the wormhole, which cannot be detected even by the most advanced radar.

The Gemini civilization is said to have the detection technology that can discover wormholes within a certain range, which is also the most secret strategic-level technology within their civilization! ”

"Yes! Whoever has this strategic advantage will probably have a headache! Yuri frowned.

"Hmmm! Know yourself and your opponent, since you want to carry out wormhole defense, then the understanding of wormholes must also be put on the agenda, communicate with Mr. Captain Ghost to see if you can get more detailed wormhole information! General Hu said.

"Hmm!" The other two nodded.

……

Knowing himself and knowing his opponent, Nie Yun naturally didn't think of this layer, and as soon as he successfully crossed the wormhole, a piece of information had already been sent to Yu Lao's hands.

"Shhh Wormhole observations?! When Yu Lao saw the report that Nie Yun had just sent to him, his expression was intertwined with astonishment and excitement, and his expression was quite wonderful.

There is still a 30,000-word professional analysis report? There are all kinds of strange astronomical data in the report, and even Yu Lao, an astrophysicist, knows a little about it.

Forget about the observation data, what is the matter with this kind of scientific research report that is clearly described in the tone of an expert?

How do you do it?

Could it be that the boss captured a group of Gemini scientists and tortured them? Yu Lao's heart suddenly came to mind......

Looking at the completeness of the information, this torture method ...... It's against the sky!
