Three years later.

The Imperial Astronomical Bureau, which received a special extraterrestrial wave, was sent using the lingua franca of the galaxy.

After the radio waves were deciphered, the meaning was clear and clear.

The main person in charge of the Astronomical Bureau immediately held an economic meeting to discuss countermeasures.

The official of the Extraterrestrial Liaison Department said:

"It's the radio waves from that alien fleet."

"It's very succinct, let's stop developing and get ready for them."

"A single qiē of this star system, including us, will be their property."

Boom -

The conference room burst into laughter.

"Haha, hahaha......"

"The aliens probably want to keep us in captivity as zoo animals, give us a piece of land, and then let people buy tickets to visit?"

"Aliens are really funny, this bit of IQ is estimated to be sent to death when they come."

……

In recent years, the extraterrestrial liaison department of the Astronomical Bureau has received more than tens of millions of interstellar broadcasts, and the information contained is endless.

A small half, before the destruction of the weak civilization, sent a distress broadcast, full of desperate cries, "Help us!" We are about to perish. "Save us, good civilization!"

There is also a part of the message, which is a diplomatic message...... "I am XX civilization, and we want to make friends with you." "I am XX civilization, and we can carry out exchanges in science and technology, economy and trade."

There is also a part of the territorial information...... "I am the XX civilization, I own the XX stars of the XX star field, you must not cross the border, and you must not violate our territory." ”

The Liaison Department learned from some territorial information that the star system to which Blue Mercury belongs belongs belongs to the territory of a fifth-level civilization named Zhenlan.

The Zhenlan civilization has a territory of more than 100,000 stars, and these territories include six or seven fourth-level civilizations, more than fifty third-level civilizations, and more than three hundred second-level, first-class, and primitive civilizations.

That is, it is only within the fifth-level Zhenlan civilization. There are nearly 400 civilizations, large and small.

Divide it by 100,000, that is to say, the probability of the number of intelligent civilizations appearing in this star field has reached 4 in 1,000.

4 thousandths...... That's more than 100 times denser than scientists previously estimated at 1 in 30,000.

The perimeter of Blue Mercury alone is so crowded...... How can this massive galaxy be imagined?

From the perspective of civilization hierarchy, in addition to the fifth-level Zhenlan civilization, there are sixth-level civilizations, seventh-level civilizations, and even eighth-level civilizations that claim to have ownership of this galaxy.

Outside of the eighth-level civilization, in another galaxy. There are also ninth-level civilizations that have ownership of this galaxy.

Outside of the ninth level, I don't know if there is a tenth-level civilization...... After all, a level 10 civilization must have the ability to break the barriers of the universe.

The ninth-level immortal dragon civilization in another parallel universe has not been able to break through the tenth-level in nearly ten billion years, and the possibility of a tenth-level civilization appearing in this universe should not be great.

Of course, in addition to distress broadcasting, diplomatic broadcasting, and territorial information broadcasting, there is also a small number of interstellar broadcasting, which can be said to be very peculiar.

But the value is very high.

There is a sixth-level civilization before it is destroyed by another sixth-level civilization. After packaging all their scientific and technological information, it was sent to the vast universe in the form of free, and their request was very simple: if other civilizations received the technical information they sent, they would be upgraded to a sixth-level civilization. Ask them to defeat the civilization that destroyed them and avenge them.

This is called "technology diffusion information".

Of course, there are also some interstellar travelers, starships, interstellar cruise ships sent messages for help, star field exploration information, mysterious ruins information, and so on...... Maybe there are very high interests in it.

Some of this information is very true. Some are deceptive and are collectively referred to as "messy messages".

The messages sent to Blue Mercury by the aliens can be classified as "territorial information" or "messy information".

……

Wen Jichu discussed with his colleagues for a while. Quickly reported this news to Tianming.

……

That group of aliens sent an ultimatum to the Empire?

Tianming was slightly stunned and asked for details.

"That group of aliens, it seems to be called the Wuga civilization."

"It's a third-level civilization that controls 400 stars, including our galaxy."

"It's just that their civilization's technology is limited, and they can't break through the faster-than-light flight technology, and they say that they have a territory of 400 stars, and I estimate that they can manage 100 of them......"

"They sent us an ultimatum, presumably because they saw that we were developing too fast and threatened their expansion plans, so this civilization issued an intimidation against us!"

"We are not afraid of this kind of intimidation, mainly because of the war potential behind this civilization...... Even if we mobilize the resources of 10 stars, we will have to drink a good pot. ”

"And in another seventeen years or so, they will come, Your Majesty, what are we going to do?"

Wen Jichu said with some concern.

In the war between civilizations, apart from science and technology, all that remains is resources.

Even if the empire has fully developed this star system and created hundreds of millions of starships, in the face of that Wuga civilization, if they mobilize 100 million starships from one star system, ten star systems will be a billion, and a hundred star systems will be ten billion.

The war potential is incomparable.

If the empire wants to go out and create greater glory, the resources of a star system may not even be comparable to a third-level primary civilization, let alone the fourth-level civilization and fifth-level civilization above......

This is also the reason why the Astronomical Bureau of the Empire has only accepted interstellar broadcasts instead of sending interstellar broadcasts: once the coordinates of the star system where the empire is located are exposed, I am afraid that it is easy to arouse the vigilance of the surrounding civilizations, and even invite annihilation.

Tianming pondered for a while and said, "We don't have to pay attention to the threat of aliens. ”

"But the pace of our development must be further accelerated."

Tianming made a call to Jiang Yuan, the head of the Imperial Army Department.

"Now, how many C-class ships are there in the Empire?"

"There are 144 ships in total, of which 120 are assigned to the four fleets on the Imperial Frontier, and the other 24 are incorporated into the Imperial Guard."

Tianming's brows furrowed heavily, "Three years have passed, how can you produce such a C-class battleship?" It's too slow, right? ”

Jiang Yuan, who was on the other side of the screen, said with a bitter face: "I also want to hurry up, throw away the technical difficulty, just the materials needed to build C-class warships are too many, and one will require at least 5 billion tons of various metals...... The mining speed of mining equipment cannot keep up with the speed of materials! The production of 100 ships a year is almost the limit. ”

"Aliens will come in more than ten years, how can a hundred ships a year be enough? At least 3,000 ships are needed. ”

Jiang Yuan's eyes widened, "Three thousand, on average, isn't it more than ten ships to be built in a day?" We can't do it! ”

C-Tier ships aren't just about materials.

It integrates a second-generation curvature engine, a 10 million megawatt spar energy reactor, a super-powerful particle cannon, a high-power laser cannon, and state-of-the-art space storage and rune shield technology...... It all requires some special means to achieve it.

For example, the second-generation curvature engine would have been impossible to make without the help of Celestial's ability.

And this curvature engine needs to consume a huge amount of mental power to drive...... But where in the current empire are there so many people who can provide enough mental power?

Is there a behemoth weighing 5 billion tons, how many people are needed to act as "human-shaped batteries" to power the curvature engine?

There is also spar energy, which is a special substance found in the core of the planet after Tianming completely stripped the barren star...... Its structure is extremely compact, the density is very huge, and the amount of a small key can weigh millions of tons.

Because this core material of the planet, which is shaped like a crystal, stores a huge amount of energy inside, and when excited, can produce ten times more energy than ordinary controllable nuclear fusion power stations...... It is collectively referred to as "Crystal Energy".

In the core of the planet, the content of "spar energy" is very minimal, take the barren star that is close to the size of the earth, for example, in the core of the star, Tianming only gets a spar slightly larger than the size of the TV...... It is this spar that can provide 500 C-class warships with enough energy supply for 50 years.

But it's only five hundred, and once the five hundred C-class battleships are built, the five hundred and one C-class battleships will have to wait for Tianming to strip off the heart core of the second big planet.

There is also the rune shield, which requires a large number of lines to be engraved on the surface of the starship...... This work can be done by the machine, but the requirements for the material are very high, and the material must have good adherence characteristics.

Finally, there is mining, a star system with sixteen main planets: nine solid planets and seven gaseous or semi-gaseous planets...... After Tianming took away the barren star and the golden giant, there are now only fourteen main planets left.

Of course, it is better to mine on solid planets other than gaseous and semi-gaseous states, but except for blue mercury and red giants, the environment of the other six solid planets is relatively harsh, some are extremely hot, some are completely frozen, and some are too gravitational...... There are only two or three suitable for large-scale mining.

Add to that the refining efficiency of mining equipment, transportation problems...... It has always constrained the speed of the manufacture of starship battleships.

"Another problem is that there is an extreme shortage of manpower, whether it is the workers who build starships or the engineers who maintain the mining and refining equipment! We need at least 10 million workers to have enough people in this area, but we have less than 2 million. ”

After smashing all these problems, Tianming understood why the manufacturing efficiency of C-class warships was not up to speed.

He thought for a while and said, "I will help you solve this problem, and strive to improve the production efficiency of C-class warships within three years!" ”
