This time, Green City was quite calm. Humans had too many contacts with foreign civilizations in the northern border, and the number of diplomats was seriously overflowing.

The increase in strength also brings more courage. The new generation can't wait to see what the external civilization is.

"Everyone, please be careful not to be impatient." Lu Yuan gave a few simple instructions in the investigation room.

"After all, there is no strange crisis in the northern border, nor is there a great survival crisis. The civilizations of Pangu continent all emerge from the bloody storm. We must maintain necessary vigilance and willingness to fight, and peace will exist by fighting for peace."

"Okay, let's start contacting."

The whole step is not much different from the past.

A translator stood in front of the speaker and shouted loudly: "[Trade! Legendary masterpiece! Spirit!]"

This sound formed a storm and swept through it at an extremely fast speed!

The faces of the rat craftsmen standing aside were twisted into a ball. What era is it? Why are they still copying us?

However, this sentence is indeed quite good, with a bit of a barbaric flavor, but instead of starting a war on its own initiative, it will make the opponent unable to understand it.

After about ten minutes, the other party responded, and the content was completely shocked.

【Hello of unknown civilizations.】

[We are the Akagang civilization, with a great sky city and a massive army.]

[We are heading to the ruins of higher civilizations in the distance. Is your destination the same as us?]

"What... the remains of higher civilization?"

"They know about the high remains?!"

In the perception of the people, the higher relics, that is, the [Temple of Greedy], are similar. Many people immediately felt unreal, and then they were a little vigilant and doubted the authenticity of this message.

"Don't act rashly." Lu Yuan frowned slightly, "This 'high-level ruins' may be a wide-ranging message, so that most civilizations in this area know it. Otherwise, the other party would have hidden it and could not be revealed directly."

As the owner of the [Greed Temple], he was a little guilty, fearing that the [Greed Temple] would mislead everyone.

A senior military executive said: "Invite them to meet and show their strength in a friendly manner. Other words will lead to mistakes."

"It's true, but civilizations that mainly use hot weapons no longer need cold weapons to fight." Old cat said with a shaking head.

"Then we will focus on displaying thermal weapons and treble weapons."

Everyone in the conference room sorted out their words and wrote a letter.

[We are human civilization, love peace and stability, advocate harmony and development. We are very happy to meet you in the vast ocean.]

[I suggest that cities on both sides should maintain a reasonable distance and display scientific and technological weapons such as suspended fortresses, supersonic fighters, treble missiles, etc. to reduce the possibility of strategic misjudgment between the two sides.]

[After demonstrating military strength, then negotiate and trade.]

After sending this letter, Lu Yuan took a deep breath: "All troops, set off!"

12 floating fortresses started from the port of Green City, releasing densely packed and millions of drones!

These drones are like bees, through lights and themselves, forming the shape of a green city, then forming the shape of a human, and even forming the appearance of a missile!

This is not only a show of skills, but also a military deterrence.

Immediately afterwards, the treble fighter started from the suspended fortress. The aircraft, called "Veoron-99", was loaded with three shock-detonation engines, and the fuselage was engraved with a large number of drifting glyphs, which could increase the speed to the terrifying Mach 15! And the missiles it loaded were naturally all hydrogen bombs!

A total of more than fifty treble fighter jets have drawn white arcs in the blue sky and white clouds.

"Missile launch!"

One of the fighter jets projected a small hydrogen bomb of 5,000 tons equivalent from a distance of one thousand kilometers.

Accompanied by the flames like the sun, the hydrogen bomb exploded.

This is actually a muscle-showing behavior, because the larger the equivalent of hydrogen bomb, the easier it is to manufacture. Instead, the more difficult it is to miniaturize hydrogen bombs.

At this time, even the new generation who was excited could not help but become serious. The external environment is no longer the northern border, and the truth here is to stop fighting.

"Oh, there are no friends here."

...

After a long time, the other party's city seemed a little surprised by the military power of human beings.

Or maybe it was the first time they encountered this kind of "gambling fighter jets".

After half an hour, several floating fortresses flew out of the "cloud group".

There are seven ships in total!

The large diameter is 2 kilometers and is in the shape of a flying saucer.

Smaller ones are like airplanes, with two wings and are more flexible.

In fact, you can't judge the combat effectiveness from the appearance. Everyone's fortresses are all cement trunks, so the eldest brother doesn't laugh at the second brother.

However, if there is an extraordinary thing like "Orika Hicks" that can replace the "Pandora Crystal", the spacecraft will have higher maneuverability.

The glyphs flashing on the walls show that the supernatural science of this civilization has made good progress.

Immediately afterwards, the Akagang civilization imitated humans and dispatched more than 100 fighter jets—the speed was about Mach 2, which was actually quite good. The top fighter jets on Earth were at this speed.

The human "Veoron-99" treble fighter has excellent performance, but is expensive and requires a lot of participation from craftsmen and cannot be mass-produced.

If an aircraft is made using pure materialism, it will be a little more than Mach.

It seems that I feel that I am lagging behind a lot, and the Akagang civilization also fired a hydrogen bomb!

This hydrogen bomb was tested by an intercontinental missile and accelerated to a maximum speed of 7 times the speed of sound!

Its equivalent is much larger than that of humans, a full million tons!

From the perspective of human beings, thousands of kilometers away, in the distance between the sea and the sky, a dazzling white light suddenly tore the calm sky, as if the sun was falling on earth!

The light was extremely fierce, and even the air was trembling. The sea water was reflected like melted silver liquid, vaporized in large quantities, forming a white cloud of mushrooms.

The clouds formed by the evaporation of water vapor blocked the dark clouds.

"From the current military perspective, it is a second-level civilization." Many young people in the command center talked one after another, "and they have good attainments in the fields of idealism and materialism... they are slightly worse than dwarf civilization, and I think they are close to the strength of the long-haired clan."

"However, the existence of hydrogen bombs is indeed a weapon of peace. I don't know how many hydrogen bombs they have... Radioactive materials are very scarce in Pangu Continent."

If a hydrogen bomb with a equivalent of million tons is directly placed in Green City, it will also cause considerable trouble. Whether it is a level six master or a level seven master, it is impossible to survive the power of the hydrogen bomb.

According to the current defense project, the AK shield will be scrapped if it consumes a few more hydrogen bombs. Fortunately, the "Light Curtain Lingyan Shield" can completely defend against hydrogen bombs, but the cost of activating the light curtain in the entire city is relatively high.

Because of this, the chance of fighting each other is greatly reduced.

Next, the translators in front began to have a "cordial and friendly" exchange with the Akagang civilization. The two sides agreed to keep the city at a distance of 10,000 kilometers, and then go to the so-called "relics of higher civilizations" together.

In addition, floating fortresses will be dispatched for face-to-face consultations, trade and negotiations.

Aka Gangwen obviously already knows the two common currencies of Pangu Continent, namely Lingyun and Civilization Points.

But in addition, they actually proposed something called "value".

I saw the other party reply: [Is it the first time you have been there for your civilization? I am honored that it is also our first time to go there.]

[We have sent diplomatic teams in advance and took the lead to the ruins of higher civilizations and learned a lot of knowledge.]

[The high-level ruins are extremely large in scale, with a lot of aliens living, and dozens of civilizations gathered around them, making it a good place for communication.]

[However, that ruin does not receive any spiritual charm or civilization points. You need to use the "value degree" to buy high-level items.]

[According to the information we obtained, the value that a civilization can obtain is quite limited. It can be obtained quickly at the beginning, but it can obtain slowly later.]

[The method of obtaining value is also quite simple. Those strange people buy everything and sell everything, from technological creations, to idealism creations, to art, animals, plants, and population. However, they only buy everything once, and they don’t want it the second time. Therefore, value is a very special unit of currency, and the amount of acquisition of powerful civilizations and weak civilizations will not be much different.]

Looking at these explanations, Lu Yuan couldn't help but feel a little curious.

It is normal for a civilized ruin of trade-types to have a stranger manipulate it behind his back. Isn’t his [Shrine of Greed] faked like this?

But what does it mean to not collect spiritual rhyme or civilization points?

How did this remains be maintained?

Translation experts typed a line: "What is the full name of this civilization ruin?"

But this line of words was not sent directly, and Lu Yuan hesitated for a while and asked them to delete them.

"Invite them to talk face to face and find out everything."

Because when I met Lan Peng civilization, I met a [Demon] and all humans almost failed.

Now, Lu Yuan dares not be lazy in foreign exchange matters, and he meets with the "Greedy Demon God".

In the first diplomacy, more than 300 people were screened out, including scientists, translators, soldiers, etc.

These people entered a small floating fortress and carried some small gifts, such as fruit, wine, Crystal East Valley, and some literary works from the North.

The most precious of them is naturally a "spiritual plant field".

Lu Yuan plans to open up the "spiritual plant field" that is introduced into "field industrialization". As long as you are not my enemy, I will dare to sell it to you!

That's it, after everything was ready, the floating fortress rushed towards the destination slowly.

On the contrary, the Akasteel civilization sent the largest fortress.

The agreed location between the two sides is 6,000 kilometers away, which is almost the midpoint of the two cities.
