The alarm bell inside the Broken Sky Ring Fortress is loud, and the red indicator light representing danger is constantly flashing.

When Gundam saw this scene, his face changed drastically, and he blurted out, "It's not good, the Broken Sky Ring Fortress is under attack." ”

The fleet of the Golden Steel Civilization moved to the vicinity of the Broken Sky Ring Fortress, and they directly launched the strongest attack.

Directly twenty-five kilometers of high-density metal-mass projectiles, after which they are accelerated to sub-light speeds. The hyperspace device ejected it, and in an instant it was near the fortress.

While the Jingang civilization attacked, it released a high-energy signal that could not be concealed. Immediately detected by the Fractured Ring Fortress.

The main base of the space artillery, which had been prepared long ago, immediately launched a rapid counterattack under the guidance of radar.

The huge energy fluctuations quickly calmed down, and Li Hao immediately observed the damage to the Split Sky Ring Fortress.

The fact that he can be safe here means that the Broken Sky Ring Fortress has been able to withstand the first wave of attacks from the Jingang Civilization.

Li Hao discovered that the Split Sky Ring Fortress had not been penetrated by the space weapons of the Jingang Civilization. Most of its shell is sunken down about a hundred meters, but it is still capable of defense.

Seeing this situation, Gundam said in a relaxed tone: "It seems that the technology of the Key Laboratory has worked, and we can't lock the Jingang Civilization Fleet now, so we can only passively counterattack."

But they won't be able to take our Broken Sky Ring Fortress either. Our strategic goals have been met. ”

Li Hao looked at the shell of the Split Sky Ring Fortress with a broken shell, and he said worriedly: "Will the shell of our Split Sky Ring Fortress be slowly worn away by the Jingang civilization. How thick it is. ”

He has carried out detailed inspections of the Broken Sky Ring Fortress, mainly important systems such as energy supply systems, logistics support systems, weapons systems, and defense systems.

The thickness of the Split Ring Fortress, a simple technical indicator, he hadn't paid attention to yet.

Gao Da said confidently: "Mr. Li, we all go through the space passage when we go out of the Sky Splitting Ring Fortress, so there is no need to leave a passage to enter and exit.

It is a large tightly fitting hood, the thickness of which is 10,000 kilometers thick built from composite materials. The thickness of the earth is just over 6,000 kilometers.

Now the Split Sky Ring Fortress is partial, and it has only been laid down by the Jingang civilization for more than 100 meters.

We've just received a signal from the space cannon to wipe out two members of the Steel-Gold civilization.

Every time they attack, we fight back. They simply could not withstand our counterattack.

If the Jingang civilization has no other way, our Split Sky Ring Fortress is impregnable. Definitely not missed. ”

After listening to Gundam's introduction, Li Hao exclaimed, "You have done a good job, and this has completed our set strategic goals. ”

It is only now that he has completely relaxed, and the safety of human civilization is guaranteed.

If the Broken Sky Ring Fortress is well guarded, they will have no weaknesses.

Even if the Jingang civilization ventures to walk through the Becky Black Hole, through the territory of the Dog Clan, and through the stellar belt of white dwarfs. Li Hao has a way to stop them.

He prepared a big gift package in the white dwarf star belt, and if the Jingang civilization really wanted to go there, Li Hao would definitely let them know why the cosmic danger was terrifying.

After the attack of the Jingang Civilization Fleet, Iron Hydride looked confident, waiting to reap the fruits of victory.

He saw that the metal mass bullet had attacked the fortress of human civilization without hindrance.

Iron Hydride smiled triumphantly, but what awaited him was a space bomb fired from the Human Fortress.

The two planetary mechanical lifeforms of the Golden Steel Civilization near the Broken Sky Ring Fortress were set on fire. Each was besieged by more than a hundred space cannons, and was smashed to pieces in an instant.

"Withdraw, withdraw." Iron hydride immediately issued an emergency order.

"How can this be, our metal mass bomb can easily penetrate even a planet. What kind of material is this fortress made of, and why can it withstand our attacks? ”

Iron hydride was shocked, he didn't expect that the qualitative assault regiment that shook the Jingang civilization would actually sink into the sand next to a small civilization fortress.

Nitrogen Oxide Copper walked to the side of Iron Hydride, and he said with a solemn expression: "I have collected the data of the attack just now, the defense of this fortress is too terrifying, I hope the captain of the fleet will carefully consider the next choice." ”

After he finished speaking, he passed on the situation of the attack on the fortress of human civilization just now.

The metal mass bullet of the Jingang civilization was just in contact with the shell of the fortress of human civilization.

The shell of the fortress of human civilization emitted a blue light.

The structure of the metallic mass projectile changes suddenly. It goes from a strong, high-density metal alloy to a high-density metal alloy powder.

The energy released by high-density metal alloy powder, he is much worse than high-density alloy.

The metal alloy powder hit the fortress of human civilization, and the shell of the fortress was only slightly damaged, blocking the attack of the Jingang civilization.

Iron Hydride was unwilling to say: "During an attack, each ship continues to attack one point. I don't believe in how thick the defensive shell of human civilization can be. ”

The Jingang Civilization Fleet once again attacked the fortress of human civilization, this time only attacking the nearest point according to them.

After the Jingang civilization made a move, it was counterattacked by human civilization. That is, the fleet has been prepared, and it still pays the price of one death and one disability.

Iron hydride exuded an aura of rage, and he looked at the copper oxide.

"How about this time, break through the fortress of human civilization?"

The tone of ferric hydride was anxious and there was a hint of expectation, waiting for the good news of copper nitrogen oxide.

Nitrogen oxide copper said helplessly: "Our attack this time penetrates a distance of one kilometer. It still hasn't broken through the shell of the fortress of human civilization.

I don't know how thick the shell of the fortress of human civilization is, and every time we attack, we pay for the lives of our people.

We use the lives of our people to explore the thickness of this fortress, which is a bit unworthy. ”

Iron hydride said tangledly: "Let's go, I will personally ask for support." Thinking that in the turtle shell, we can't do anything.

It is terrible that this civilization must not be allowed to develop. ”

When he evacuated, he shouted over interstellar radio: "Human, you wait for me, I will definitely come back." When the time comes, pierce your tortoise shell. ”

When Gundam received the information, he said excitedly: "The Jingang Civilization Fleet can't deal with us, they retreated. We won. ”

Li Hao said indifferently: "We still can't relax, they are in the strategic initiative, and we are in the strategic passivity."

The Jingang civilization took advantage of their mobility and could come back at any time.

We still need to be vigilant, especially when the radar has failed.

After all, the Jingang civilization is higher than ours, and who knows what trump card they have. ”

Gundam immediately said solemnly: "Please rest assured, Mr. Li, we will definitely do our best to resist the invasion of the Jingang civilization." ”

"Just remember one thing, don't leave the Broken Sky Ring Fortress. They can't deal with the Broken Sky Ring Fortress, and the best way to do that is to lure you out. Li Hao instructed.

Gundam promised: "We will pretend to be turtles to death, and we will never go out to fight the Jingang civilization." ”

"That's not what I said, I'll go back to the Key Laboratory and let the scientists solve it. Even if I tell you, you will not be able to defend against it. Li Hao thought of the weakness of the Split Sky Ring Fortress and sighed a little.
