After more than 20 days of flight, Zhao Yu finally returned to the moon.

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

The situation on the frontline remains the same. For more than 20 days, both sides each consumed nearly 50,000 warships.

Correspondingly, Zhao Yu's technology points have also increased to 130,000. Not to mention the particle black hole transformation, even the type 3 particle black hole form is almost redeemable.

"Sir, welcome back!"

Just after landing, I saw Uncle Da standing at the entrance of the base to greet him, just like the scene before when Zhao Yu returned from an outing.

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

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

Zhao Yu was stunned when he heard this, "Is there any?"

"Yes!"

Uncle Da quickly took out a mirror, Zhao Yu looked at it and said, "No!"

Immediately afterwards, a photo that was taken before leaving more than a year ago was revealed by Uncle Da.

"Sir, look at this, this is what you looked like when you went out to war..."

After this comparison, Zhao Yu immediately saw the difference.

In the photo, he looks quite sunny, as young as a young man in his twenties, with bright eyes.

As for myself in the mirror, my temples are white. Although my appearance does not seem to have changed much, the light in my eyes is much dimmed, and my whole person is much calmer.

After some comparison, I look more like a man in his thirties who has gone through vicissitudes of life in the mirror.

"Yeah, I'm getting old..."

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

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

Based on the current situation of the Blue Star humans, they can only live to be about 120 years old without any disease or disaster.

After a brief exchange of greetings, Zhao Yu hurriedly entered the base control room.

After more than a year, Zhao Yu felt more at ease when he returned here again.

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

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

[Base: Level 2]

【Experience:/】

【Technology Points:】

I haven’t been back for more than a year. The base is still at level 2 and the experience points have not changed. Fortunately, there are 130,000 technology points, which is enough to raise the technology level to the mid-to-late stage of level 2.

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

Entering the base control room at this moment, Zhao Yu immediately started exchanging money in a bold manner.

Basic technologies have been developed one after another, and the levels of various weapons-related scientific research centers are also rapidly improving.

In just one hour, 130,000 technology points were spent.

[Base: Level 2]

【Experience:/】

[Technology point: 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 Sciences:2.50】

Except for life sciences, which only improved to 2.5, the other six basic sciences all improved to 2.70.

This level can be regarded as meeting the prerequisites for manufacturing type 3 particle black holes.

Once you have enough technology points, you can redeem them directly.

"Only 60,000 technology points are needed to reach level three..."

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

In addition, the role of the reputation system is far beyond imagination, and it can be redeemed for high technology that exceeds the base level limit.

The frontline can maintain its current situation entirely because of the light needles that were exchanged for reputation.

"Unfortunately, most of the 22 civilizations' progress bars 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 reputation system has not refreshed more powerful weapons, so he can only take one step at a time.

Fortunately, there are still more than 200,000 enemy warships on the front line. If they are destroyed all, the technology points they gain will be enough to upgrade the base to level 3.

When the time comes, if we fight openly and honestly, we may not lose to that Mo Dou civilization.

……

"Still no change?!"

"No!"

In the Proxima Alliance station, Dugo frowned slightly. He asked several times from the headquarters, but he didn't give anything new.

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

After Dugo pondered for a moment, he said: "In this case, let's send a fleet into the solar system to have a look!"

Just use the battleships of the other five second-level civilizations to test it, and I'm afraid it won't have any effect in a short time.

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

In his first trial, Dugo did not dare to send more troops. He only ordered a thousand battleships and sent them to the solar system.

Unlike the five major civilizations, Dugo's order for these thousand warships is to directly destroy the enemy's frontline base. If the opponent does not respond, continue to attack and destroy Blue Star.

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

Du Ge didn't believe that even if they had done this, the enemy would not show up.

……

"This battleship shape..."

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

According to records, this is the first fleet to appear in the Proxima Galaxy, and it should be a battleship belonging to the third-level Mo Dou civilization.

"Are they finally sending a battleship over?!"

Amid Colonel Chu's worries, the battleships near the wormhole outside Proxima Centauri disappeared. There is no doubt that they have begun to travel through the wormhole.

"Get ready to retreat!"

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

This was something he had discussed with Zhao Yu in advance. Once the battleships belonging to the third-level civilization were deployed, they would abandon their frontline bases and retreat to the rear.

"We can't escape very far in one day. Now we just hope that the other party won't spend more time on us..."

Colonel Chu didn’t know that the third-level civilization already had the ability to accelerate through wormholes, and he only thought that it would take a day for the other party to arrive.

During the escape phase, tens of thousands of warships were arranged. Except for a few ships with live people, most of them were controlled by robots.

Once the frontline base is destroyed, these tens of thousands of warships will disperse to try to avoid being blamed by the opponent, and at the same time, it can also distract the enemy's attention.

I had just boarded the battleship and less than an hour after flying away from the frontline base, a thousand more battleships appeared on the gravitational wave detector.

"So fast?!"

Colonel Chu was shocked. After carefully checking the situation, he determined that this was the fleet that disappeared from the Proxima Centauri wormhole.

He suddenly realized that the warships belonging to the third-level civilization could travel through the wormhole at a much higher speed than the warships belonging to the second-level civilization.

Upon seeing this, Colonel Chu quickly recorded this information, and together with the logs of these days, had them sent to Zhao Yu through Quantum Realm News.

The enemy came so quickly that Colonel Chu had given up hope that he could escape and ascend to heaven.

The number of Ruyi-type warships is limited, and most of them are placed in the rear. There are only a dozen or so on the front line, and the light needle warheads each ship carries are also extremely limited. If you want to use ten warships to fight against a thousand enemy ships, there is almost no possibility of victory.
