In addition to the improvement of economic, military, technological and other strengths in earth civilization.

Their improvement in culture and other aspects is also very significant.

That's why at this moment, you can get the invitation letter for the entry invitation of the fourth-level civilization.

However, of course Li Chen would not pay attention to the invitation letter.

Is it not good to be a level 1 civilization happily?

"Noah, it's almost time for us to attack the remaining five civilizations, right?"

"They guys, now I look very annoying..."

Li Chen looked at Noah and said in a deep voice.

With the comprehensive strength of the current earth civilization, they don't need to look at the face of any third-level civilization at all.

Moreover, the size of today's star shelters is produced by countless advanced star destroyer battle groups every day.

Become an important weapon in safeguarding the core interests of earth civilization!

Plus more than 150,000 large interstellar mining transport ship formations.

Through the installed second-generation curvature engine.

They can travel at up to half a million times the speed of light.

Every day, countless energy resources are continuously being transported back to the star shelter.

These are the current strengths of Li Chen!

great power!

Adequate logistical supplies!

And a complete industrial system!

[Host, I am about to report this situation to you! 】

[The current coalition forces of Prome civilization, Valoran civilization and Noah civilization have started to act after being silent for more than half a month! 】

[Their allied forces brazenly invaded the Gaia civilization! Now the two sides are engaged in a fierce war! 】

[I was planning to ask you, do you want to take this opportunity to clean up these civilizations! 】

Noah heard Li Chen's inquiry and reported immediately.

They have been secretly monitoring the enemy's every move during this time.

Not doing nothing for more than half a month.

Now everything is ready.

A large number of star system resources have been mined back.

Sufficient energy reserves as a star shelter.

Coupled with the rapid development of science and technology in star shelters, the current earth civilization already has the comprehensive strength of an entry-level fourth-level civilization.

In addition, the enemy began to officially break out internal strife, and several third-level civilizations attacked each other.

There is simply no better opportunity!

"After waiting for them for more than half a month, they dare not come to provoke us! Haha!"

"Now I can finally do it myself!"

"Good! Very good!"

"In this case, let's fight! Take this opportunity to unify the entire tenth area of ​​Orion's spiral arm!"

Li Chen gave the order decisively.

Let the commanders under your hands make preparations immediately and start organizing forces immediately!

"Let's start with the Pulitzer Civilization Empire first! The resources of the fifth star field look pretty good to me!"

Li Chen ordered.

But at this moment.

Suddenly they received a report from Xu Ruoxi, Mo Li and others.

"Commander, we have encountered a little trouble here!"

Xu Ruoxi sent back to contact, and explained the situation to Li Chen straight to the point.

Hearing such news, Li Chen's heart trembled slightly.

They were sent in the past to return to the sixth star field to mine special material resources specially used to build the energy core.

It has just arrived in the relevant area, and the mining tasks are being carried out in an orderly manner.

At this time encountered an unexpected situation.

Could it be that…

Are there still enemies in the sixth star field?

"Interstellar pirates?"

Li Chen frowned and asked in a deep voice.

"no!"

Xu Ruoxi immediately denied it.

"Oh? What's that?"

Li Chen's heart trembled slightly, and he vaguely felt a sense of uneasiness.

"Commander, I don't know how to explain it to you. I have already sent Noah the video impact data. You can analyze it for yourself. I'm not sure..."

Xu Ruoxi's words were unclear.

That's rarely the case with her.

Hearing what she said, Li Chen immediately looked up at Noah.

At this time, Noah also nodded to indicate that he had received the relevant information.

[Host, do you want to open it now? 】

Noah asked.

This is the highest command center,

There are many other commanders here.

"Open it! There are no outsiders here!"

Li Chen nodded and ordered.

Hearing this, Noah immediately followed suit and opened the video data sent by Xu Ruoxi.

I saw that there was a video about fifteen minutes in it.

In the video screen, there is an almost pitch-black starry sky background.

A star is dotted in it.

Looking at the screen, the star destroyer battle group of Xu Ruoxi and others is hidden in the shadow of an incomparably huge planet.

Spy on a stealth super spaceship to detect what's ahead.

At first, there actually appears to be nothing in the frame.

But soon, through the anti-stealth energy detection radar, spaceships that looked like mining ships began to appear on the screen one after another.

"It's very far away..."

When Li Chen saw the ratio of this picture to the target, he knew that Xu Ruoxi and the others were at least several million kilometers away from the target.

Possibly even further.

"Commander, this is a picture we took from a distance of 15 million kilometers with our ultra-high power spy stealth spacecraft."

Xu Ruoxi replied.

Hearing this, Li Chen raised his eyebrows slightly, but didn't make a sound, continuing to observe the situation on the screen.

Immediately afterwards, they saw more and more spaceships, suspected to be mining transport ships, appear out of thin air in the vast interstellar space.

And began to disperse, flying towards planets and stars in all directions.

"Who are these guys?"

Seeing this, Li Chen has already realized that someone is secretly stealing the resources of their sixth star field.

And it seems that the technological level of this group of people is not low.

At least their main ship, under the detection of the anti-stealth radar of the spy spacecraft dispatched by Xu Ruoxi and others, can actually remain invisible without being discovered.

Even those third-level civilizations can't do this.

"Master, we found that this group of people is stealing our resources, and the area is exactly the one you asked us to collect!"

"But their identities are unknown, and they definitely don't look like interstellar pirates!"

"We have sent nanorobots to try to sneak into the opponent's spaceship, and now we are waiting for specific intelligence information..."

"We speculate that the enemy is most likely from a fourth-level civilization, but we dare not jump to conclusions, so we will report the situation to you first."

At this time, Mo Li's voice also came back.

Hearing their words, Li Chen frowned even deeper.

"Level 4 civilization?"

At this time, Li Chen remembered what happened about a month ago.

"Noah, do you remember that huge Star Destroyer Mothership back then?"

"It was the one that crashed into our mining transport ship and the escorting Star Destroyer battle group formation in an instant!"

Li Chen asked.
