Zhang Yuan couldn't help but wrinkle his nose when he saw these parameters, 2 light minutes, this number is only a very small number in astronomical units, the distance from the sun to the earth, 1 astronomical unit is equivalent to 8.3 light minutes. 1 light-year is also equal to 63,241 astronomical units.

But for human high-precision equipment, it's a big, big number.

It is impossible to install a super-telescope with a diameter of several kilometers on a curvature missile, nor can it install a super-powerful radar, so how can it detect a small target and then guide it accurately?

As for other space weapons, such as lasers and ion cannons, they don't even have the ability to guide after being launched, and the distance they can hit is within 2 light seconds.

Yes, only 2 light seconds!

The low-speed electromagnetic cannon can only be hit within 0.5 light seconds.

Ordinary nuclear bombs are simply pitifully slow, and can only be delivered at close range using drones.

"In other words, distance is still the best way to protect civilizations from civilization to civilization."

"All in all, the curvature missile is the only weapon that can cause high damage to the curvature spacecraft at an ultra-long distance, so we still have to develop ...... Vigorous development! ”

There was silence in the room, and some of the councillors who didn't know much about it began to talk and discuss it in their ears.

Zhang Yuan swallowed his saliva, what does this general mean? is taking this opportunity to ask for money nakedly!

Isn't one curvature missile equal to a spaceship? You have to install a curvature engine on the missile, a supercomputer with an ultra-high amount of calculation, and a dark matter tracking device to vaguely judge the opponent's traces, and the cost is ridiculously high!

Oh, by the way, it's already so expensive, this missile has to be amazingly destructive, and it has to be the most powerful antimatter in it!

Even so, the hit rate is still extremely low, 1 in 10,000?

Zhang Yuan licked his dry lips, and when he saw the captain's face on the stage, he couldn't help but be happy...... Luckily, he's not the captain of this era.

Fortunately, the entire civilization is strong enough, otherwise it simply cannot afford such a high-cost weapon.

The general ignored the specialists who were in charge of state funding: "...... Through long-term military exercises, we believe that the place of action of the fourth-level civilization is no longer limited to the cosmic strings, but should avoid the cosmic strings as much as possible, because if a war is fought near the cosmic strings, high gravitational fluctuations will destroy the curvature motion. ”

"If we lose the curvature of the voyage, even if we are stronger than the third-level civilization, it will become a difference between fifty paces and a hundred...... We don't need to be at the same starting line as a Level 3 civilization. ”

Down, on the screen is the cellular combat mode in the sub-light state.

Due to the poor communication environment of the spaceship in the faster-than-light state, sub-light environmental warfare will become the mainstream warfare method of the fourth-level civilization.

A swarm of drones is like a burst of lightning, which can wipe out the targets on the planet at once, and even this "target defense system" has not reacted at all.

All kinds of sparse differences, video displays, Zhang Yuan was dazzled to watch.

He doesn't know if it's powerful or not, at least it looks pretty good, it's quite gimmicky. With his nerve reflex speed and field of vision, it was impossible to observe a semi-stealthy sub-lightspeed ship.

However, the problem is that the cost of the "curvature" drone is surprisingly high, and it has to be equipped with a quark energy chamber and a curvature engine, and the production capacity is limited, unlike traditional drones, which are disposable consumables...... It's about the same cost as a manned spacecraft, and if you want to form a swarm, you need a lot of budget money.

The last part is to show the latest weapons: electromagnetic kinetic weapons, nuclear weapons, lasers, ion cannons, etc., all old toys, but upgraded.

The latest toys are photon torpedoes, which are antimatter weapons, as well as special electromagnetic pulse bombs, capable of disrupting battlefield communications specifically.

"People have no foresight, but they must have near-term worries!"

"We don't choose to violate others, but we should have the ability to defend ourselves...... I hope that these weapons will allow us to protect ourselves in future crises! Thank you! ”

After the military representatives finished speaking, the audience burst into applause.

Next, the two civilizations began to discuss the direction of future development, and the vast majority of people still felt that they should go out and communicate with other civilizations.

If you continue to study here slowly, you may still make some progress, but it certainly won't be as big as it was at the beginning. The technology that can be excavated is almost finished.

In addition, the six large motherships are also about to be completed, and the installation of the latest curvature engines will begin, and it will be able to start test flights after some time.

So, after some discussion, people discussed their own goal - Tabi Star!

That is the Dyson ball!

This is the goal that has been reached after a long period of discussion.

Tabi Star, codenamed KIC 8462852, has been observed by humans for a long, long time.

In the 21st century, mankind has discovered a planet that periodically changes in luminous intensity. Scientists at the time were puzzled and thought that there was some celestial body that periodically obscured the star.

But after a long period of observation, people finally decided that it was a Dyson sphere, and then believed that there was an even more powerful alien civilization in the universe, which caused a huge panic at that time!

Speaking of which, this Dyson sphere has a certain relationship with the "Earth Era" project.

If this Dyson sphere is not observed, people may still be obsessed with the idea that humans are the only intelligent life in the universe, like a tribal chief on an isolated island, who is proud to rule the entire island......

The discovery of the Dyson sphere had a huge impact on human beings at that time, and it was the first to prove the existence of extraterrestrial life. Secondly...... This is simply earth-shattering power, the difference between the sky and the ant!

Whether it is panic or excitement, the discovery of the Dyson sphere at this moment has had a profound impact on the history of the entire human society.

Of course, up to now, people are no strangers to extraterrestrial civilizations, but there is still only one Dyson sphere found in the galaxy.

It's very mysterious and weird......

As far as human beings are concerned, the Dyson sphere is really useless, it is just a large solar panel, which can collect all the energy of a star, which is indeed very, very powerful, but the fourth-level civilization will not lack energy, why do it? Even if there is a real lack of energy, you can build thousands of quark energy energy rooms, instead of building a difficult Dyson sphere.

That's weird.

It wasn't until later that there was a faint speculation in people's minds.

According to the Star Road Map exchanged from the fourth-level civilization, it is a gathering place of a large number of interstellar civilizations, about 400 light-years away from its current location, and there are members of the amoeba faction who have formed a trading market there.

In other words, a planet that periodically changes in brightness can naturally attract the attention of interstellar civilizations. It has become the most important symbol of Orion's cantilever, and most interstellar civilizations will be interested in it.

Combined with this species, human beings are still very willing to go to that place to explore the truth, and by the way, they also want to invite the Thoth civilization as an ally to go together, and one more ally is always one more power.

However, after thinking about it for a long time, the Tothians actually rejected this plan: "Unfortunately, friends of the new human civilization, we are indeed very interested in that Dyson ball. But we have just gained visual perception, and it will take a long time to popularize this technology to the entire civilization. ”

"With optical perception, we collectively believe that the tech tree of our civilization is too crippled. We need to adapt to this new perception ability, and we also need to develop corresponding technologies for optical perception to adapt to the new era. So, we intend to continue to develop here for hundreds of years or so. ”

"After that, we choose to go there."

The choice of the Toth civilization was also expected, because in the course of long-term contact, this flaw was clearly discovered. The other party's choice is also quite reasonable.

With a new kind of perception, we must first study its safety, and then slowly popularize and adapt, and develop new adaptive technologies. Maybe all the existing machinery and equipment will have to be modified, which is a huge amount of work.

And there is no need for human beings to wait for three or five hundred years, the so-called gentleman's friendship is as light as water, and most of the time, people still have to rely on themselves.

And just like that, after the meeting, all the Tothians boarded their ships and prepared to leave. Before parting, people also gave away some cheap technology, such as LCD screens, foldable personal mobile phones, clocks, computers, VR glasses and other things, these technologies are very cheap, but very useful.

If the other party really adopts these things, they may have more common topics when they meet in the future.

Finally, the two sides said goodbye to each other.

"May your civilization always progress ......"

A standard interstellar etiquette.

The life that truly knows the connotation of this set of rituals will never despise it in any way, and knows its weight.

Zhang Yuan, as a representative of civilization, bent down slightly: "I also hope that your civilization can continue to progress." ”

"Goodbye, friends."

……

The Thors civilization has launched its ship and left, and the new human civilization will embark on a new journey......

Target, Tabi Star!
