Du You, who was originally going to cultivate Sera, saw that Sera offered to follow, and Du You agreed.

"By the way, how far away are those asteroids, and how long will it take to end the battle?"

"We're pretty close to that, and we can get there in about a month at the speed of a transport ship. Don't think that a month is a long time, this is already a very short time, and the other party will definitely not be able to build any powerful combat power in such a short time. It's not a territory like ours, and it takes a complete industrial system to build. ”

Du You sighed, how did he feel that time was becoming less and less like time. Well, these people on the technology side are really completely different from themselves. "Then you can do it yourself, and I'll take care of my business too. ”

With that, Du You walked out and looked outside, Du You said depressedly: "It's all useless things." ”

"Master, what are you talking about?" Lin Yushi asked a little strangely. Before, in the command headquarters, the two sisters couldn't say a word, but now that they are out, Lin Yushi has regained her lively personality.

"I'm talking about those dark elemental dragons, if they had been bred in the first place, they would never have been so miserable this time. Each Dark Elemental Dragon is definitely no worse than a ship of the same level, this is a thousand. If they had helped before, these warships would have died as many as they came. ”

No way, I don't know if it's because of the different rules of different worlds, these dark elemental dragons have been bred for a long time, and they haven't been successfully conceived until now.

As a result, when fighting before, the other party thought that this was some kind of secret weapon, and most of them were blown up in one round of attacks. Now these blasted elemental dragons are about to be reborn.

The Black Dragon Tower doesn't play much of a role, there is no way, the defense of the battleship is too strong.

After the other party arrived, the elemental pool attached to the Black Dragon Tower began to attack automatically, but unfortunately this attack was not strong enough and was blocked by the battleship's defensive barrier. And the battleship did not notice that this thing was attacking. Otherwise, there would have been attacks that would have landed on the elemental pool, or even on the head of the Tower of the Black Dragon.

The loss of a magic tower is incalculable. There is no magic tower to shield the laws of the world, so that the IQ of civilians will not be suppressed. If your own civilians want to train it, it will cost more and the effect will definitely be worse.

Looking at this tattered territory, Du You felt a burst of anger. The journey has been smooth until now, and it is the first time that Du You has been beaten to his hometown and beaten his territory so badly.

Shaking his head, Du You opened the panel, and at this time, the task of resisting the enemy's attack had been completed.

Although in this mission, because there were too many people cooperating, Du You didn't have many things. However, with the completion of this task, there is still a treasure chest.

"Let me see what's in there. Hey, it's kind of rewarding. ”

Du You's eyes lit up, in addition to the crystal coin, there were two drawings. However, this is not an architectural drawing, but a blueprint for a technology item, and this type of design is very common in this type of technology world.

"The design drawings of the air combat ball require a technological weapon production factory or an air-type building. Yes, my Air Force headquarters and automated weapons production plants can be built. I'll see, the Air Force Command has more production capacity, so let's hang on it. Du You threw the blueprint into the tattered Air Force headquarters.

The next moment, a new icon appeared in front of Du You.

Air Combat Ball Level 29: 500 pieces/month, full price 100 Green Crystals/piece

After producing one, Du You found that this thing was not one of the weapons dropped by the enemy before, and the combat effectiveness of the weapon was constant at level 29, which was the same type as those satellite railguns.

Able to fly at low altitudes, the flight speed is not very fast, and the defense is not very strong, but the attack is powerful and flexible enough. The territory, which had just lost a lot of combat power, finally recovered a little.

This thing is not of high level, and it is impossible to transport it all the way to the opponent's base to fight. Just dispatch some Blu-ray mechs this time, small soldiers, and the academy will help you solve it.

Du You looked at the second drawing, this is the frigate drawing, frigate type 5.

"This frigate should belong to the battleship type, it's good, it can really merge with my spaceport. Du You put the two drawings together, and sure enough, they merged all at once.

When your own spaceport is established, you will be able to add a warship of the Frigate Type 5.

In space operations, warships are the main force, and only when they have enough fleets can they be able to attack, retreat, and defend. A territory without a fleet can never be considered a powerful territory.

Besides, on Earth's side, its own garden star also needs a fleet. There seem to be a lot of interstellar pirates outside recently, and although they don't dare to come in, they can't expel these guys themselves.

Du You looked at his territory experience, and after this battle, his territory experience had improved a lot. If you go up a little more, it will be enough to reach the fifth order. It is easy for large worlds to level up, and this kind of interstellar type of world, as long as there is enough strength and achievements, it is fast to raise the level.

According to Du You's calculations, waiting until the opponent's three asteroids are counter-killed this time, this is a classic battle. After the promotion of the Star Ring Alliance, there is no problem at all when the territory reaches the fifth order.

Thinking of the battleship that was about to be built, Du You was excited.

"Hmph, let you come and fight me, I will have a fifth-order battleship at that time, I want you to look good. "The fifth-order battleship is already considered the main battleship in the Star Ring World, second only to the sixth-order main battleship, and it can be regarded as the number among the major forces.

It's just that Du You's performance is really a little childish. The two sisters watched it funny and endured it very hard.

After a long time, after finishing the two drawings, Du You found that there seemed to be nothing to do. Because I've basically done my own thing, I'll leave the rest to someone else. As for the development of the territory, you can't do it on your own. It seems that it is necessary to communicate with the major territories and the other side of the earth as soon as possible.

"Let's go, let's go back first, and we'll come back when the space passage is established. ”

The two sisters nodded slightly, and the two of them would not refute Du You's decision. Coming to the secret room that had been built a long time ago, Du You directly avoided the others and opened the space passage. No one knew that at this important time, their lords would leave their realm and return to Earth.
