The moon base I built was exposed

Chapter 169 Shocked, Level 4 Civilization Appears!
After more than 20 days of flying, Zhao Yu finally returned to the moon.

During this period, he has also been paying attention to the developments on the front line, and from time to time communicated with Colonel Chu through the Quantum Realm Technology.

The situation on the front line remained the same as before. In more than 20 days, the two sides each consumed nearly [-] warships.

Correspondingly, Zhao Yu's technology points have also risen to 13. Not to mention the sudden change of the particle black hole, even the type III particle black hole shape is almost ready to be exchanged.

"Sir, welcome back!"

Just after landing, I saw Uncle Da standing at the gate of the base to greet him, just like the scene when Zhao Yu returned from going out.

"I haven't seen you for more than a year, you are still the same!" Zhao Yu said with a smile.

Uncle Da looked at Zhao Yu carefully, "Sir, you have more white hair on your hair..."

Zhao Yu was taken aback when he heard the words, "Is there any?"

"Have!"

Uncle Da quickly fetched a mirror, and Zhao Yu looked at it, "No!"

Immediately afterwards, Uncle Da revealed a photo left before he left more than a year ago.

"Sir, take a look, this is what you looked like when you set off..."

In this comparison, Zhao Yu immediately saw the difference.

In the photo, he looked quite sunny, as young as a boy in his 20s, with piercing eyes.

As for the self in the mirror, his temples have turned white. Although his appearance doesn't seem to have changed much, the light in his eyes has dimmed a lot, and he has calmed down a lot.

After some comparison, the self in the mirror is more like a man in his 30s who has gone through vicissitudes.

"Yeah, old..."

Zhao Yu sighed with emotion. During those days on the front line, he was under a lot of pressure in his heart. Unknowingly, his image changed.

Just a few days ago, he used the medical machine to check his body, and the results showed that he was very healthy, but people will eventually grow old one day.

With the situation of their Blue Star humans, they can only live to be around 120 years old without any disease or disaster.

After exchanging pleasantries for a while, Zhao Yu hurried into the base control room.

After more than a year, returning here again, Zhao Yu felt at ease.

Although the system is always with him, the base is his core. Once the base is destroyed, everything about him will be gone.

Fortunately, it is now level [-]. In addition to the moon base, there is also a sub-base on the mothership of Bell's Comet.

【Base: Level 2】

【Experience: 110800/300000】

[Technology points: 134231]

I haven't been back for more than a year, the base is still level 2, and the experience value has not changed. Fortunately, there are 13 technology points, which is enough to raise the technology level to the middle and late stage of level 2.

Regarding the upgrade of the base, Zhao Yu had discussed it with Uncle Da in detail during the 20-odd days on his way back.

Entering the base control room at this moment, Zhao Yu directly exchanged it drastically.

One by one basic technology has been pulled up, and the level of various weapon-related scientific front yards is also rapidly improving.

In just one hour, 13 technology points were spent.

【Base: Level 2】

【Experience: 240150/300000】

[Technology points: 4882]

The seven basic sciences have also been greatly improved.

【Mathematics: 2.70】

【Logic: 2.70】

【Astronomy: 2.70】

[Planetology: 2.70]

【Physics: 2.70】

【Chemistry: 2.70】

【Life Science: 2.50】

Except for life science, which only rose to 2.5, the other six basic sciences were all pulled to 2.70.

This level can be regarded as meeting the prerequisites for the manufacture of type III particle black holes.

It can be exchanged directly when there are enough technology points.

"It's only [-] technology points away from level three..."

Zhao Yu is very fortunate. Fortunately, he chose the title of King of War at the beginning, which allowed him to quickly accumulate so many technology points in a short period of time.

In addition, the role of the prestige system is far beyond imagination, and it can be exchanged for high-tech that exceeds the limit of the base level.

The front line can maintain the current situation, all thanks to the light needles that were previously exchanged for reputation.

"Unfortunately, most of the progress bars of the 22 civilizations have stopped moving..."

Zhao Yu is also very clear-headed. Once the enemy finds out that they only have light needle weapons and no other more powerful weapons, they will be greeted with a fatal blow.

But now, the prestige system has not refreshed more powerful weapons, so he can only take one step at a time.

Fortunately, there are more than 20 enemy warships on the front line. If all of them are destroyed, the technology points they get will be enough to upgrade the base to level 3.

When the time comes, they will fight dignifiedly, and they will not necessarily lose to that ink fighter civilization.

……

"Is there still no change?!"

"no!"

In the Proxima Alliance resident, Du Ge frowned slightly. He asked several times at the headquarters, but he didn't give anything new.

This made the headquarters somewhat doubt whether there is really a third-level civilization in the solar system, and even asked Du Ge to confirm the matter as soon as possible, and the pressure came over immediately.

After pondering for a moment, Du Ge said, "In this case, let's send a fleet into the solar system to have a look!"

In this way, using the other five battleships of the second-level civilization to test, I am afraid that it will not work in a short time.

After all, they still have to sacrifice part of their own fleet!

For the first test, Du Ge didn't dare to send more troops, and only ordered a thousand warships, and let them go to the solar system.

Different from the foreign workers of the five major civilizations, Du Ge's order for these thousand warships is to directly destroy the enemy's frontline bases. If the opponent does not respond, they will continue to attack and destroy Blue Star.

With the strength of their third-level civilization, destroying a second-level civilization with a thousand warships is a bit of a fuss.

Du Ge didn't believe that if they all did this, the enemy would still show up.

……

"This battleship shape..."

Colonel Chu stared at the battleship that appeared near the Proxima wormhole, feeling a little frightened.

According to the records, this is the first fleet to appear in the Proxima Galaxy, and it should be the battleship of the third-level ink fighter civilization.

"Are they finally sending battleships over?!"

Amid Colonel Chu's worries, the warship near the wormhole in Proximity disappeared. There is no doubt that it has begun to travel through the wormhole.

"Prepare to retreat!"

Colonel Chu quickly sounded the alarm, telling all living people to leave the frontline base, board the battleship, and prepare to retreat.

This is also what he discussed with Zhao Yu in advance. Once the warships belonging to the third-level civilization go out, they will abandon the front-line base and retreat to the rear.

"One day, you can't escape very far, now I just hope that the other party won't spend too much time on us..."

Colonel Chu didn't know that the third-level civilization already had the ability to travel through wormholes to accelerate, and he only thought that the other party could reach it after a day.

In the escape link, tens of thousands of warships were arranged, and except for a few with living people, most of them were controlled by robots.

Once the frontline base is destroyed, the tens of thousands of warships will be dispersed, trying to avoid being taken over by the opponent, and at the same time distract the enemy's attention.

Just got on the battleship, and within an hour of flying away from the frontline base, there were a thousand more battleships on the gravitational wave detector.

"So fast?!"

Colonel Chu was startled. After examining the situation carefully, he determined that this was the fleet that disappeared from the wormhole of Proxima Centauri.

He suddenly realized that the battleships belonging to the third-level civilization can travel through the wormhole at a much faster speed than the battleships belonging to the second-level civilization.

Seeing this, Colonel Chu quickly recorded this information, and along with the logs of these days, sent someone to Zhao Yu through Quantum Realm News.

The enemy came too fast, and Colonel Chu had no hope of being able to escape and ascend to heaven.

The number of Ruyi warships is limited, and most of them are placed in the rear. There are only a dozen ships on the front line, and each ship carries extremely limited light needle warheads. If you want to use ten warships against the enemy's thousand ships, the possibility of victory is almost impossible.

"It exploded~!"

At this moment, someone rushed to report, "Our frontline base has been bombed..."

Colonel Chu hurriedly checked the situation, only to find that the asteroid where the frontline base was located had been blown into pieces. Not only that, thousands of space fortresses with defensive facilities had also been blown up.

"Such a short time, it should be the use of light needle technology..."

In less than ten seconds, the frontline base was bombed, and there was no other possibility except light needles.

In just ten seconds, all the defense facilities of the frontline base, as well as nearly a million warships of various types, were all destroyed.

"It's over..."

The principal of Chu University sighed, knowing that he was going to die here.

At this moment, he suddenly noticed that the gravitational waves near the wormhole began to twist violently.

"what's the situation?!"

Colonel Chu turned his head and glanced at the detector that had been monitoring the situation of the Proxima Centauri wormhole, and found that there was no change there.

This shows that some warships did not shuttle through Proxima Centauri, but shuttled from other places.

"Is it their support?!"

Colonel Chu muttered to himself, and suddenly discovered another strange phenomenon.

Near the wormhole in the solar system, the more than a thousand warships that came in did not attack them. Instead, they surrounded the entire wormhole after discovering that the wormhole was abnormal.

"Aren't you with them?!"

Colonel Chu was surprised, the solar system is already lively enough, could it be that there are other civilizations coming? !

But the current situation is not bad for him, no matter how bad it is, can it be worse than it is now?

"If you come to a third-level civilization..."

He believed that if a third-level civilization appeared at this time, the attention of the Modou civilization would be diverted, and they would be safe for the time being.

The gravitational wave outside the wormhole quickly spread out for ten kilometers. Senior Colonel Chu's eyes widened, wondering what would emerge from it.

Who knows, after waiting for a long time, no spacecraft appeared outside the wormhole, and the gravitational wave was still spreading, reaching fifty kilometers in a blink of an eye.

"This?"

Colonel Chu was a little surprised. After these days of observation, he also summed up some rules.

For example, the spread range of gravitational waves is only affected by the maximum size of the shuttle warships, not the number of shuttle warships.

Even if [-] warships are shuttled at the same time, before the wormhole is about to be drilled, the spread range of the gravitational wave is based on the largest of the [-] warships.

"It's more than [-] kilometers, which has surpassed the mothership standard. Could it be another type of warship?!"

Not only Colonel Chu and the others were surprised, but also Zhao Yu and the others who were watching what was going on here on the moon were also puzzled.

And outside the wormhole in the solar system, the more than a thousand battleships and the more than 20 cannon fodder groups composed of the five major civilizations on the outer defense line also looked vigilant.

On the contrary, Du Ge and others who were far away in Proxima Centauri were a little dazed, "Why didn't they attack?!"

"How did the formation become like this?!"

"Looking at the situation, it seems that something is about to pass through the wormhole..."

"Are you coming?!"

Du Ge narrowed his eyes, guessing that the third-level civilization hidden behind the solar system couldn't sit still anymore, and it should show its real body.

Just as everyone was watching, the range of gravitational waves outside the wormhole in the solar system expanded.

From [-] kilometers, break through to [-] kilometers, then to [-] kilometers, and then to [-] kilometers.

At this time, everyone was shocked, and even a little scared, not knowing what the thing passing through the wormhole was.

A battleship with a length of a thousand kilometers is completely unimaginable.

The upper limit of the second-level civilization is to build a warship with a length of [-] kilometers, and then it is restricted by various factors and cannot be broken through.

Therefore, everyone knows that the ones who have traveled through the world are probably the real third-level civilizations.

Finally, when the length of the gravitational wave exceeded [-] kilometers, a super spaceship the size of the moon appeared.

"what is this?!"

On the front line, outside the wormhole, the people in the thousand battleships all collapsed.

Looking at the behemoth in front of me at a close distance, the appearance full of technological sense directly shattered everyone's cognition.

Level [-] civilization cannot build such a large battleship!
"Attack~!"

The commander of a battleship was nervous and gave an order to attack.

Seeing this, the other warships followed suit, regardless of who gave the order.

Countless light needles, as well as various types of weapons, spewed out and shot towards the huge monster.

Unexpectedly, this super space battleship would not dodge or dodge, allowing these attacks to hit.

The next moment, the super space battleship suddenly blurred, and all the attacks passed through his body, as if these attacks were not in the same dimension as it.

Immediately afterwards, all the attacking battleships, at this moment, seemed to have gone crazy, and flew towards the super space battleship.

The moment the two came into contact, all ordinary battleships disappeared, as if swallowed by a super space battleship.

At this moment, no matter whether it was the six major civilizations in the solar system or the whale army in the neighboring galaxy, they were all shocked.

"Level 4...Is it a level 4 civilization?"

Du Ge's teeth were chattering a little. He didn't expect that there was a fourth-level civilization hidden behind the solar system.

"Escape!"

At this moment, he didn't dare to think too much, he just wanted to escape.

Before the opponent could react, he sat on the wormhole and escaped far away.

He reacted the fastest. After simply giving the legion an escape order, he was the first to drive the command ship into the wormhole and escape from the neighboring galaxy.

In the solar system, after the super space battleship stopped in place for a while, it split into a small battleship only ten kilometers away, and flew towards the direction of the blue star.

Then, under everyone's incomprehensible gaze, this super space battleship did not destroy the more than 20 other warships that were onlookers. Instead, it instantly turned into a giant light, flashing and disappearing from everyone's sight.
