Due to the lack of satellites and aircraft, the concept of war of the Taipu civilization is still generally stuck in the era of giant ships and cannons. Whoever has more troops, the more fierce the artillery, and the higher the combat effectiveness of either side. And in order to overcome the friction of the air, the mass of the cannonball is extraordinarily huge, and it is completely an enlarged version of the shell that humans once shelled.

In addition to the giant ship artillery, there is also a mode of war - that is, using airboats to deliver missiles and bombing the ground, whichever side can fly higher, then, which side will be invincible.

"War is never far away, ah......"

Just as I watched the TV, a streamlined airship arrived, and O'Brien hurriedly ate his breakfast and boarded the airship with the crowd of passengers.

Immediately afterwards, the air pressure pump sounded "suddenly", and quickly inflated the surrounding auxiliary airbags, and with the increase in the volume of the auxiliary airbags, the empty boat was very smoothly lifted into the air.

The top speed of this kind of airboat, codenamed "Lin Qibai", can reach a maximum speed of 80 kilometers per hour, and in the city, each public airboat has its own route, and its rated speed can reach about 50 kilometers per hour.

Fortunately, there are direct stations between stations, and there are no intermediate stations, so this speed is still acceptable.

Since there is no way to build high-rise buildings, and the population that can be accommodated per unit of land is small, this civilized residential area is like farmland, neatly spread out piece by piece, and the central core area must be an empty boat parking place.

O'Brien's place of work is at the Observatory's meteorological office, 50 kilometers away, which can be reached in just an hour.

When he came to the Astronomical Observatory, he found that the atmosphere inside was as usual, most of the colleagues gathered together to chat casually, and the working day had not officially begun.

The Astronomical and Meteorological Observatory is mainly responsible for the exploration of the outer starry sky and meteorological monitoring.

Of course...... Mainly the latter.

The climate requirements of the airboat navigation system are still quite high, whether it is windy weather or heavy rain weather, it may lead to traffic paralysis. This also requires the meteorological station to be able to predict the weather conditions more accurately and issue timely notifications.

O'Brien's greatest wish was to launch a real weather satellite...... There was such a project in the plan, but it eventually died because the technical difficulty was too high and the financial requirements were too high.

It is very difficult for the whole country to even create an airborne vehicle, let alone launch a rocket.

So the amount of money spent on starry sky exploration is very, very small, and everyone thinks that if we think about it in a few years after the technology is developed, maybe we can save a lot of money?

And they haven't used artificial satellites, and most of the Taipu people don't think this kind of thing is very urgent, can't they live well without satellites, and can't they accurately predict the weather? These meteorologists are the only ones who are eager for satellites, but the appeals of these experts are often of little use.

"Tomorrow is a new tomorrow, and the government allocates millions of dollars every year, at most to maintain a not too big astronomical telescope, satellite? At this rate of development, it is unlikely that there will be another century! ”

O'Brien sneered in his heart, complaining about the lack of eyes of the politicians. Without visible benefits, it is impossible for politicians to allocate funds.

A large number of scientists are sharpening their heads and thinking about how to make the airship fly higher, and all the money is invested in the airship. Since the failure of the last plan, the people of Taipu have not bothered to think about other aircraft that can produce qualitative changes. There are even many people who directly believe that it is impossible to be able to fly in the air with an iron bump.

"What's the weather like today?" As he thought so, a colleague greeted him.

It's not just a casual greeting, it's their job.

Since there are no satellites, climate observations must be made through the airboat observatory above. Radio communications and computer technology have already appeared on this planet.

O'Brien glanced at the data on the computer and came back to his senses: "It shouldn't be too much of a problem...... Of course, this is just my empirical judgment. Now our area is in a state of high pressure, there is a downdraft, and the probability of rain is scarce...... The humidity of the air is also not great. ”

"It's been another easy day." The colleague stretched lazily, as if he hadn't woken up.

Just then, suddenly, a computer in the next room emitted a "Didi" alarm.

"It looks like a radio interferometer is observing a signal from outer space."

This kind of thing is not once or twice, any neutron star, pulsar, and even the solar wind may have electromagnetic wave signals. The planet's atmosphere is thick enough that even the most violent solar winds have a negligible impact on the planet.

"I'll go check it out, it's good to record it."

O'Brien trotted over and recorded the signals into the storage device. He suddenly discovered that these signals, with certain rules, were more like the universal telegraph code of the Taipu civilization.

"It's good that I learned the language of the telegraph......" he scratched his head, and after tapping on the keyboard, the whole translation came out at once.

"Unknown civilization, hello, we are a human civilization from afar, with peace and goodwill."

"We abide by the principle of equality and free trade, everything can be bought, everything can be sold, as long as you can pay the corresponding price......"

"We ......"

When he saw this line of text, the colleagues who came to join in the fun around him laughed dumbly, "I bet it was some idle guy who sent this message on the empty boat...... Even the code is our telegram code, could it be that we Tepu people have inadvertently conquered the entire universe? ”

"Bet on what? A lunch? I'm going to invite you. O'Brien didn't pay much attention to it, and began to try to manipulate the space telescope: "But the direction of the radio waves does come from space." ”

"Their spacecraft stays above the atmosphere, really? You're so bored, so you have to look for it, and be careful of being scolded by the stationmaster. The colleague was still chattering next door, his eyes fixed on the screen: "Hey??! ”

"It's ...... What the?! ”

His voice grew louder, almost from a bland sentence, to a huge scream!

"Outside...... Alien! ”

A large wave of colleagues heard this scream and hurried over, thinking that something had really happened.

There really was a small shadow in the telescope!

Seem...... Staying at an altitude of 60,000 kilometers, no airship can fly to an altitude of 60,000 kilometers, there is no atmosphere at all.

There was a deathly silence in the air, it was incredible!

Aliens, aliens really appeared.

Everyone in Tepu held their breath, as if their brains had shut down, and after a few seconds, the Organic Spirit hurriedly ran to find the leader.

"Turn up the resolution ten times more!" When the stationmaster of the meteorological station heard the news, he also hurried over, and he said in a trembling tone.

O'Brien swallowed, his face not very pretty.

The shadows on the screen gradually became clearer.

Vaguely you can see that there is not just one ship, but ...... 10 ships!

There are a total of 10 ships, moving above the atmosphere!
