The boundary can also be a reminder of the warships of other countries.

When another warship is about to enter the territory, it will release a strong beam of light to remind the other party that this is our territory.

Back on the Elemental Planet, Ye Yu sent a message to Li Xue, and then also transmitted the production technology of the boundary line, he needed to let Li Xue produce this kind of boundary equipment in the shortest possible time.

He hadn't found out that the Lieyuan Kingdom and other countries were okay before, but now he needed to establish a border, which had both advantages and disadvantages.

If you establish a boundary, it will be a bit difficult to detect the outer planet in the future.

However, as long as there is strong force, no one dares to stop even the exploration and mining of other planets.

After Streich and the others left, he hurriedly transmitted the news here again: "The other party has advanced and powerful light-speed class interstellar battleships, three have been discovered so far, and nine warships of the same level as ours have been discovered, but it is estimated that they still have a large number of interstellar warships, this country is called the Galactic Federation." ”

Soon the news came back from the headquarters of the Lieyuan Kingdom: "Don't offend them, we will send an envoy to see what the situation is there." ”

Ye Yu did not leave in the follow-up, and stayed on the elemental planet all the time.

In seven days, a C-class battleship came to the Elemental Planet with a large number of boundary equipment, and then began to lay out the boundary in the territory detected in the galaxy according to Ye Yu's request.

Each planet in the vicinity of the territory has to be equipped with a boundary device, and according to the current scope of the territory, they currently need to arrange more than 400 boundary devices.

However, these are nothing, the industrial production capacity of the Galactic Federation is now very terrifying, and the production speed is very fast, six hundred boundary devices have been produced in five days.

There are C-class warships, and it took less than two days to arrange these boundary equipment, and the territory of the early stage of the Galactic Federation is roughly determined.

Ye Yu never left on the Elemental Planet, because he knew that there would definitely be someone from the Lieyuan Kingdom in the future, and he was waiting here.

Ten days later, a hundred D-class warships arrived on the nearby planet of the Elemental Planet.

This is almost the entire power of the Galactic Federation, and there are only a few starships left on the Blue Star side, including two C-class warships and a few D-class warships.

At present, the eight production bases are all working hard to produce starships, and each production base can produce about 20 ships per month if it is fully operational, and the eight production bases can build a large number of starships in a month.

In the past, most of them were producing interstellar mining transport ships, but now the number of transport ships has reached three or four hundred, and without so many, there will be no endless resources to supply the production of interstellar warships.

These mining transports are fundamental, and there would not be such a high production without so many mining transports.

It has been a month since the people of the Lieyuan Kingdom left, and it is estimated that the people of the Lieyuan Kingdom will come here in more than a month.

During this time, Ye Yu also went back to Blue Star for a while, mainly thinking about his two children, and he didn't see them grow up a lot for more than a month.

Maybe it's because of the genetic drugs, the two little guys are already able to talk and run around on the ground.

After staying at home for a month, he felt that the time was almost up, so he took Xue Wanqian to the Elemental Planet again.

Five days later, space observation satellites again observed a fleet, a large number of starfleets, heading in the direction of the elemental planet.

Ye Yu also set off with the fleet to meet him, and the two sides met near the boundary line.

A voice came from there: "We are the fleet of the Fifth Legion of the Lieyuan Kingdom, I am the diplomatic ambassador of the Lieyuan Kingdom, Bellock, I heard that there is a powerful and prosperous Galactic Federation here, and at the order of our king, I have come to establish friendly relations with your country in order to promote trade exchanges between our two sides." ”

Ye Yu heard his words, and replied in a light tone: "Our Galactic Federation welcomes the diplomatic ambassador of the Lieyuan Kingdom, but what do you mean by coming so many warships?"

Belloc: "I don't know what you call it?"

"My name is Ye Yu. ”

Bellock: "Mr. Ye, we have no other meaning to bring so many ships here, the road is far away, and it is inevitable that we will encounter interstellar bandits, who are protecting the safety of our mission." ”

Ye Yu: "If you want to come to our Galactic Federation, you can do it, but these warships are not allowed to enter, and we will guarantee your personal safety." ”

Those people's faces were slightly stunned when they heard Ye Yu's words, it seems that the other party's vigilance is very high.

They thought for a moment and replied, "Yes." ”

Later, a flying machine flew over to pick up the people from the Lieyuan Kingdom mission, and there were more than a dozen people in their mission.

The flying machine picked them up onto Ye Yu's battleship.

Ye Yu This is the first time he has seen people from alien civilizations, they are similar to the people on the Blue Star, some are like the Westerners on the Blue Star, and some are like the Easterners.

The people led by them looked at Ye Yu and Xue Wanqian: "Hello Mr. Ye, I am Bellock of the Lieyuan Kingdom. ”

Ye Yu nodded slightly: "Hello, Mr. Bellok." ”

"May I ask Mr. Ye, are you the leader of the Galactic Federation?" Bellock asked.

Ye Yu: "Sort of, I can call the shots about the Galactic Federation, everyone who comes to visit our Galactic Federation, I'll let someone take you around the galaxy first, and we'll talk about something else when you're done." ”

Belloc nodded: "Well, okay, trouble Mr. Ye." ”

Then they were sent to other warships, and Ye Yu had a smile on his face, then you should take your time first, and come to me after a few months.

A few months is enough time for Ye Yu to produce a lot of interstellar warships, and then he doesn't have to worry about any Lieyuan Kingdom.

Unbeknownst to Belloc and the others, they were about to embark on an interstellar voyage for a few months, and by the time they reacted, it was already a few days later.

After Ye Yu arranged those few people, he left here, but there were many interstellar warships parked on the border, and he was also worried that the Fifth Fleet of the Lieyuan Kingdom would attack directly.

Ye Yu and Xue Wanqian returned to the Blue Star, and they could develop steadily for a few more months.

Back on Blue Star, Ye Yu accompanies his children every day, and then occasionally writes some advanced R&D technologies and transmits them to the company's brain server.

This kind of confidential technology is only allowed to be viewed by Li Xue, and no one else can see it.

He is now making some preparations for the future, and if one day he is not on Blue Star, Blue Star can also develop steadily.

After the diplomatic mission of the Lieyuan Kingdom sailed in the starry sky for seven days, they began to react, and then asked the battleship Zhi Brain to contact Ye Yu.

"Where are you, Mr. Ye?" asked Belloc as he saw him.
