On this day, people around the world who have not slept discovered the abnormality for the first time.

"The phone is out of signal?!"

Many people think that it is just that their mobile phones have no signal, but they don't know that this is a global electromagnetic wave disorder caused by the Star Destroyer cannon.

The duration will be as long as a month, during which time people will return to the wired network era and all mobile phones will be moved to bricks.

Not to mention the 6G network, not even 2G does not exist.

What followed was an earthquake that was felt all over the world.

People in almost every region felt the tremors clearly, but they were not frequent and the damage was not great.

Some knowledgeable seismologists were puzzled, and the measuring instrument did not respond, which means that there was no earthquake in the country, but the earthquake was felt from underfoot.

"Unless, unless, there's a huge earthquake coming from farther away, and all we feel here is aftershocks......"

Earthquake experts were all shocked, and if confirmed, it would be an unprecedented earthquake.

With no cell phone signal, no way to make phone calls, and frequent earthquakes, many people realize that something may have happened at this moment.

But the spread of information is not smooth, and all people can do is go home and turn on the cable TV and wait for the news.

……

"Sir, you're going to Earth?!"

Listening to Uncle Da's questioning, Zhao Yu was a little weak-hearted, he hadn't discussed this matter in advance.

When I was negotiating with Colonel Chu, I added it myself, because I was afraid that Uncle Da would not agree and wanted to make it an established fact.

"Ahem, negotiation, I have to go out, they can't do it, it's easy to be manipulated......"

"I know, I'll make a fleet to protect the captain's safety as soon as possible......"

What Zhao Yu didn't expect was that Uncle Da didn't jump his feet.

Don't dwell on mistakes, just choose the best at the moment?

Zhao Yu suddenly realized that Uncle Da is like a human no matter how human, he is still just an artificial intelligence, and in terms of emotions, there are not many unnecessary emotions.

"Sir, the first phase of the plan has been formulated......

Uncle Da didn't dwell too much on this matter, and talked about what Zhao Yu had explained before.

"Well, tell me about it!"

"For our base, there are two main things lacking......"

"First, science and technology, this is the core, can upgrade science and technology, develop new industrial ......"

"Second, resources, which are necessary to be able to mass-produce combat machines......"

"The biggest benefit for us to trade with Earth should be the return of tech points for the title of 'Mystery Merchant'......"

"Resources, in the short term, we do need the resources of the earth, but in the long run, there are many barren planets in the universe, and the resources are almost inexhaustible......"

Zhao Yu nodded slightly, the eight planets in the solar system, except for the earth, the resources on the other planets are ownerless, who comes first and gets it.

After thinking about it, he asked again: "How long is the window to land on Mars?" ”

The eight planets of the solar system all revolve around the Sun, sometimes on the same side as the Earth and sometimes on the other side.

When on the same side, the natural distance is the shortest, and for spacecraft with limited spacecraft, it is the best landing period, also known as the window period.

"11 months to ......"

Uncle Da shook his head and said, "Sir, in the first phase of the plan I set up, there is a mission to send a spaceship to Mercury......

"Mercury?"

Zhao Yu was stunned, he was very unfamiliar with this planet, and he only knew that it was the closest planet to the sun.

Uncle Da nodded and continued: "Our spacecraft now has two power modes, one is magnetic, and the other is nuclear......"

"Magnetic power is not very practical for interstellar navigation, after all, most of the universe is barren, and there is no strong magnetic force to borrow......"

"If you go to other planets, you can only rely on nuclear power......"

"Our fusion reactor technology is now in its second generation, with conventional nuclear-powered spacecraft traveling at only 61,400 km/h......"

"At this time, if you want to go to Mars, it will take 88 days to get to ......"

"And, even if they do, they won't be able to return to ...... until two years later."

The closest distance between Mars and the Earth is 55 million kilometers, and the longest distance is 400 million kilometers.

Otherwise, according to the farthest distance, the time on the light path will be consumed for more than a year.

"Venus's conjunction with us has an average period of 584 days, and it is now about 110 million kilometers away from us, and it has not yet reached the farthest point, that is, the next conjunction will be about 290 days later, which is longer than Mars......"

Zhao Yu understood his words and asked, "What about Mercury?" ”

"Mercury is 83 million kilometers away from us, and 218 million kilometers away......"

"The good news is that Mercury orbits very fast, with only 88 Earth days, an average of 116 days to meet the Earth, and is now in the conjunction period, which is the window to Mercury......

Zhao Yu nodded and asked, "Send the spaceship over now, how long will it take?" ”

"57 days."

"So long?"

Uncle Da nodded and said, "Therefore, the core of our second-phase plan is to upgrade the second-generation nuclear fusion reactor to the third-generation ......."

"Upgrading nuclear fusion?"

Zhao Yu's brows furrowed slightly, nuclear fusion almost runs through the core of the entire technology below 1.99, and the exchange price is also rising.

The first generation of nuclear fusion, when exchanged, only cost 1000 science points.

But the second-generation nuclear fusion has become 5,000 technology points, and it took more than half a year to save up in order to upgrade.

Similarly, the third-generation nuclear fusion requires as many as 10,000 technology points, and Zhao Yu never thought about upgrading at all.

"Yes!"

Uncle Da nodded and said: "Nuclear fusion is the core, according to calculations, if nuclear fusion is upgraded to the third generation, the speed of all our nuclear-powered spacecraft will be increased on a large scale......"

"In addition, all facilities involved in nuclear fusion, such as energy shields, ground-based laser defense systems, etc., will also increase in power......"

These are supported by nuclear fusion reactors, and when nuclear fusion is upgraded, the natural tide rises and the boat rises, and it will become stronger together.

Zhao Yu thought about it carefully, and it really should be upgraded to the third generation of nuclear fusion.

I didn't think about it before, because all the science and technology points are all about saving, and 10,000 technology points need him to save for two years.

Now, with the title 'Mystery Merchant', he can quickly gain a lot of tech points from the Earth side.

"Yes, is the first phase of the plan to trade heavily with Earth?"

"Yes!"

Uncle Da nodded and said, "My idea is to use that asteroid with a diameter of 50 kilometers as our base on Earth......

"Then set up a company to build factories around the world and recycle technology ......"

"The money earned on the earth can be exchanged for some resources on the earth, after all, we don't have the ability to run too far now, and the nearest Mercury at present takes 57 days to reach ......"

Zhao Yu nodded, the plan was similar to what he thought, "Is the list of transactions listed?" ”

"Lined up, maglev cars, intelligent robots, and the first generation of nuclear fusion power stations ......"
