The No. 1 college in the world starts by cultivating top scorers in the college entrance examination

So fast.

Hearing Xue Hao's words, Qin Cheng's face instantly became serious.

According to the information behind Xiao Jiu's devouring light brain, it can be known that this group of aliens should be Barnard's.

But Barnard's star is six light-years away from the solar system, and it takes six years for light to reach the solar system.

But at this time, it is only about two months before the light brain sends out the message.

It turned out to be so fast.

Qin Cheng's thoughts ran quickly.

For this doubt, he quickly thought of the reason.

The transmission method used by the light brain should be through faster-than-light particles, which are extremely fast.

Can exceed the speed of light.

This must be the reason why the light brain's information travels so quickly.

The reason why Barnard's spacecraft came so quickly is estimated to be that it traveled with curvature, directly crossing the speed of light and reaching the edge of the solar system.

So everything makes sense.

As for why they didn't cross directly to Earth, there should be two main reasons.

First, they don't know the situation of the solar system at this time, and they need to be careful.

The second is that there are so many rocky planets in the solar system that there is no way to sail in through curvature.

So they can only temporarily stop at the edge of the solar system and then come to this side of the Earth by ordinary voyage.

At this time, Qin Cheng calculated a little.

Probably in about half a year.

That is to say, around June next year, aliens will arrive on Earth.

Basically, after the New Year, everyone can detect the spacecraft through various astronomical observation instruments.

"This should be Barnard's alien fleet."

"Barnard Star? The light before was dim, could it be because a large number of spaceships blocked some of the light? When

Xue Hao heard this, he asked incredulously.

In this regard, Qin Cheng did not hide it, and nodded directly.

"That's right, in fact, Master Wei discovered this anomaly early on."

"There are many astrophysical institutions around the world studying Barnard's star, but Barnard's faint light has never been found before, so it cannot be a planetary occlusion."

"Plus Barnard's star is indeed a threshold for space navigation, so this is easy to speculate."

"And now, they've reached the edge of the solar system, and that's the best proof of that."

"This..."

Xue Hao was directly shocked when he listened to Qin Cheng's words.

Unexpectedly, Barnard, who has studied for several months, gathered a group of aliens.

"Master, what should I do now?"

"They are already approaching the edge of the solar system at this time, and it can be speculated based on the way they arrived in the solar system."

"Their technology is much higher than that of the earth, and the aliens who can perform space navigation are definitely not what the earth can face at this time."

"I hope they don't use the universe as a hunter of the forest as depicted in the three-body problem, otherwise the earth is gone."

Xue Hao spoke, his face was very pessimistic.

There is no chance of victory.

But this cannot be blamed for his lack of ambition.

Because the reality is like this, at this time, the technology of the earth, under the leadership of Qin Cheng, can use any resource on the earth.

Even soon, it will be possible to land on Mars.

Voyages within the solar system are about to begin.

But even so, it is too difficult to fight aliens.

It was an almost one-sided situation.

"Don't be so pessimistic, isn't there still Master in front of all this."

"You will now send the observation data to Zhuge Ye, and then proceed to observe the aliens."

"Quickly report to me if there is any situation."

Qin Cheng chuckled and patted Xue Hao's shoulder.

The current situation is not without a solution.

The key to this is the upgrade of the system.

Qin Cheng had a hunch that as long as the system was upgraded, then all problems would be solved.

"Okay, I'll go right away."

Xue Hao nodded heavily, and then turned to leave.

However, he was stopped by Qin Cheng again.

"Help me call Wu Hua over, he is a freshman in this class, and he is also my inner disciple, and he should be in the laboratory now."

Xue Hao heard this and thought about it.

Then I remembered the name.

The junior who launched a dog-carrying rocket in the playground before.

At that time, Xue Hao had seen it in the past, so he also had some impressions of Wu Hua.

"I'll go to him right away."

Xue Hao didn't ask anything more, and after nodding quickly, he walked out of the door of Qin Cheng's office.

"Dad, what are aliens?"

The little cotton jacket had been playing in the office and saw Qin Cheng chatting with Xue Hao about big things.

She didn't bother obediently.

Now that the two had finished chatting, they stepped forward to ask and chat with Qin Cheng.

"Aliens, come and send experience babies."

Qin Cheng picked up the small cotton jacket and laughed softly.

If there is anything, just bear it yourself, the little cotton jacket is only responsible for growing up well, and then look beautiful like a flower.

When Wu Hua was in the gap, Qin Cheng took the Bible out of the system again.

After opening it, study it carefully.

Except that the paper is a little different, the contents inside are exactly the same as those sold on a certain treasure.

For example, light was created on the first day, and then what was created on the second day.

There is no difference.

After that, Qin Cheng injected some spiritual energy, and the result did not change.

So angry that Qin Cheng exchanged more than a dozen bad luck stickers and used them on them.

This time, however, something has changed.

[The holy relic is contaminated with bad luck stickers, and there have been special changes]

The system prompts, but it is very simple.

This made Qin Cheng a little puzzled.

Later, some bad luck stickers were exchanged and used on them.

The result has not changed again.

After Wu Hua knocked on the door, he entered Qin Cheng's office.

"Master, are you looking for me?"

Wu Hua stood in front of Qin Cheng and said with a smile.

"Well, how's the recent research on Mars?"

Qin Cheng nodded, and then opened his mouth to ask about business.

"It feels okay, I have initially designed a spacecraft with the latest fusion thruster that can accelerate our exploration of Mars."

"At least the time to travel to Mars can be shortened."

Hearing Qin Cheng ask about the Mars voyage, Wu Hua immediately answered.

This is his forte.

"The average distance of Mars from Earth is 230 million kilometers, but because the orbital period of Earth and Mars is different, the distance is also different."

"At its farthest time, it reached 400 million kilometers, and in the most recent time, it was only 55 million kilometers."

"According to the current state of technology, it takes about eight months to reach Mars with electric propulsion, and about six months for fossil fuel propulsion."

"With our latest fusion thrusters, three months is enough, or even two months or so if it is faster."

"But it should be noted that these need to be launched at Mars opposition, which means that spacecraft need to be launched when Mars is closest to Earth."

Wu Hua said slowly, introducing the situation of sailing Mars one by one.

The opposition of Mars is the day when the Sun and Earth and Mars are in the same straight line, and it is also the closest day between the Earth and Mars.

Generally, spacecraft going to Mars will launch during this time.

When Qin Cheng heard this, he spoke.

"Slow down!"
