Li Chen had already asked Megatron to bring a large number of special nano-soldiers, as well as the newly-controlled shooter civilization troop with more than 300 million combat power, into the sixth area of ​​the shooter civilization.

And now these hundreds of millions of combat forces belonging to their Earth Civilization Alliance are lurking in the entire Archer civilization.

Megatron cooperated with S2K, waiting for Li Chen to give them combat instructions.

They are ready to fight at any time and cooperate internally and externally.

And Li Chen, using the technology of the seventh civilization, ordered their scientists and engineers to help transform the power system of the original star destroyer battle group formation of the earth civilization.

The third-generation curvature engine, the limit speed can no longer meet the current combat needs.

One light-year per second seems to be very fast, but in terms of long-distance combat missions of tens of thousands of light-years.

Such a speed simply cannot meet the combat needs of a level 4 peak civilization.

After all, the opponents they are facing now basically have the fourth-generation curvature engine as standard configuration.

In addition to upgrading and refitting the fleet commanded by Li Chen himself with the fourth-generation curvature engine.

Li Chen also ordered the seventh civilization to help them upgrade and improve weapon systems, defense systems, stealth systems, and so on.

Especially the technology of detecting stealth targets by using the principle of antimatter resonance.

Li Chen attached great importance to this technique.

Earth civilization has been relying on powerful anti-stealth capabilities and stealth technology to crush their opponents on the battlefield.

For example, when they fought against the Massim civilization and the iron-blooded civilization, they fought against the old civilizations in the tenth district.

It is precisely because the earth civilization has more advanced stealth technology and anti-stealth technology.

That's why they can predict the enemy's opportunity everywhere, and they can accurately intercept the raiding enemy's fleet every time, so that the enemy has no power to fight back.

But such advantages have disappeared since meeting the evil **** civilization and the seventh civilization.

The fleet of earth civilization can no longer fight in stealth.

In front of the enemy is equivalent to streaking.

This makes many of their previous tactics based on the advantages of stealth and anti-stealth technology unusable.

In the final analysis, the essence of interstellar war is to compete for technological level.

Whoever has better technology will win the final victory.

The level of science and technology is not only reflected in the power system of the ship, but also in their weaponry system, defense system, detection capability and so on.

In addition, there is the efficiency of energy storage and utilization and so on.

Each of these items may determine the final outcome of a war!

So now there is still some time, and there is such a suitable opportunity, of course Li Chen will not miss it.

He must improve the technological level of the earth's civilization and the comprehensive combat power of the combat troops.

"Master, don't worry, we will definitely follow your orders and make everything as perfect as possible!"

I heard Li Chen say that after the upgrade of his fleet is completed, he can set off to fight against the archer civilization.

The Mechanic King immediately made a promise.

Li Chen glanced at him with satisfaction and nodded.

"After completing the task, don't forget to reward the technicians."

"If you behave well, there will be no less that should belong to you."

"Thank you, master!"

On Li Chen's side, the Seventh Civilization was upgrading its fleet at the same time.

The advanced scientific and technological materials from the evil **** civilization and the seventh civilization also arrived at the headquarters of the earth civilization.

Scientists began to study these advanced technologies day and night.

And use these advanced technologies to start promoting the development of the entire earth civilization.

On the other side, the shooter civilization in the sixth district.

In a hidden intelligence station.

S2K met Megatron here and shared the information he had investigated.

And draw up a battle plan with Megatron.

"The Sagittarius civilization is a civilization dominated by carbon-based life forms. It is very similar to our previous earth. The races here are almost all carbon-based life forms."

"And one of the characteristics of carbon-based life forms is that they must obtain energy through eating and drinking every day."

"In terms of eating, they are no longer limited to ordinary food, because ordinary food contains too little energy to meet their energy needs."

"But drinking water is a must. Whether it's pure water or energy liquid that combines highly concentrated energy, they will always come, even high-level people are no exception..."

While talking, S2K transmitted the detailed list of the main living supplies here, the characteristics of each food and drink, and other data to Megatron.

"They are much more advanced and developed than the original Earth. They have a very advanced and efficient supply system, which can provide every member here with timely and sufficient guarantee of survival materials."

"That's been very helpful for us."

As he spoke, he showed another map.

On the three-dimensional space map of the holographic projection, there are densely packed lines.

He pointed to the countless criss-crossing lines on the map and explained.

"These are the Sagittarius civilization, the current water supply system of the main planet Sagittarius Planet. We only need to find the source and put a special potion there. It won't take long for the entire Sagittarius Planet to fall under our control."

"In addition, we have also investigated the water supply routes on other planets of the Sagittarius civilization, and they are all here."

S2K tapped the map a few times, and shared all the data with Megatron.

After receiving these data, Megatron immediately nodded solemnly.

"I will send people to carry out these tasks."

"Don't be so anxious!"

S2K reminded.

"how?"

Megatron looked back suspiciously.

"Although the Archer civilization did not master nanotechnology, they knew that such nanotechnology existed, so their scientists created a barrier that could defend against nanotechnology."

"This barrier is specially used to protect important facilities, such as energy supply systems, life support systems, and more!"

"If you can't find a way to break these barriers, you won't be able to get in..."

The words of S2K reminded Megatron that they attacked the enemy's fleet before.

At that time, they also tried to control the power room of the enemy's Star Destroyer.

However, it was discovered that even the nano-special fighters could not sneak into the target area by means of nano-robot avatars.

Later, I had no choice but to give up.

Now it seems that this should be the kind of technology that can limit the infiltration of nanobots.

"If this barrier is breached, will it trigger an alarm?"

Megatron recalled the previous events, and couldn't help but feel a little thump in his heart, and became a little worried.

If this kind of barrier is invaded and the alarm is automatically triggered, doesn't it mean that they have already been exposed?
