……

On April 27, 2384 A.D., the people in the chariot could also feel the roar of the earth.

Everyone was very panicked and didn't know why, but Lu Zhengxing comforted everyone confidently not to panic.

Seeing Lu Zhengxing's determined expression, everyone stopped panicking.

After consuming a lot of scarce materials and metals, Mingjing finally completed the final upgrade of this Mingyue 3000.

Now the Mingyue 3000 is already the size of a minibus, and according to the design of the star, he can further increase the space.

For Mingjing, he really wants to rectify this car in place, but the earth is now in a special period, and it is difficult to get hold of many rare materials.

Qiao's daughter-in-law was embarrassed to cook without rice, and this time she finally found a lot of useful things in Yao Pojun's munitions warehouse, which made Mingjing feel very good.

Lu Zhengxing finally opened his mouth and asked with concern: "Leader Ming has done a good job, you have worked hard this time." ”

Mingjing's answer was very strange: "It's not hard, it's not hard, who made my life hard!" ”

Lu Zhengxing heard that there was a sense of strengthening the rod in these words, obviously when Mingjing was doing these things, Lu Zhengxing couldn't help with a little help. Although he is engaged in technology, the current technical level of this car has far exceeded the level of earth technology for many years.

Lu Zhengxing cheekily asked: "What is the technical level of this car now?" ”

Mingjing's answer was simple: "Level 2.5." ”

The answer was so simple, and it aroused Lu Zhengxing's curiosity: "What is level 2.5?" ”

Mingjing proudly explained: "Being able to break through the gravitational pull of the planet is a civilization level of 0.5, and the star system where the manned spacecraft can fly is a level 1.0 civilization standard......"

Hearing Mingjing's story, Lu Zhengxing was very depressed in his heart, it turned out that with the current civilization level of the earth, he couldn't even reach the standard of a first-level civilization.

Hearing that the Dark Water Civilization had closed the earth, Lu Zhengxing asked curiously again, "What level of civilization has the Dark Water Civilization reached now?" ”

Mingjing's reply was, "Higher than level 4." ”

It's very sad to get such an answer.

When an earthlings know that the enemy who imprisons the earth actually has such a high level of civilization, it will inevitably make the earthlings feel discouraged.

Lu Zhengxing was thinking, in the past three hundred years, the earth has been tossing and turning all day long, and he has not done anything serious.

Technology has barely developed, and there are hardly any major changes from 300 years ago.

If there is a change, it is that there are more movie stars, people have more leisure time, the names of sports activities are becoming more and more numerous, there are countless sports associations, and various amusement facilities are more sound.

Lu Zhengxiong remembered that before the end of the world, he once saw a statistic, according to statistics, there are 2 billion people engaged in sports-related industries in the world.

I know that the total population of the earth in the last days was only 7 billion.

Nearly one-third of people are busy with sports-related things all day long, so the progress of science and technology will naturally be affected.

Lu Zhengxing was thinking nonsense in his heart, but Mingjing didn't pay attention to him.

Mingjing knew in his heart that after he finished this upgrade, this car would not have to deal with the upgrade for a long time.

The earth began a new round of shaking, and the people in the car were a little dizzy.

Hearing such a vibrating sound, Lu Zhengxing understood that this was Yao Pojun carrying out the plan he had agreed upon again.

In a sense, the more severe this shock, the happier Lu Zhengxing was in his heart, which showed that Yao Pojun could cause more and more Yao Guang.

With the increase in the number of Yaoguang, the ability to destroy the iron shell of the Dark Water Civilization will also increase in the future, which is a good thing, so in the middle of the bumpy road, they are still laughing, and the other women in this car are very puzzled.

Yao Pojun must have started to try to activate Yao Guang's huge energy, Yao Guang swept, and the mountains and rivers trembled.

Mingyue 3000 floated gently from the ground and headed down the pitch-black valley towards the depths of the Seven Immortals Valley.

The car moves through the air off the ground so that the vibrations in the car disappear.

Their next target was the second mountain in the Valley of the Seven Immortals, named Kaiyang Mountain.

This Kaiyang Mountain is naturally named after Kaiyang Star, the second star of the Big Dipper.

Little Lori took the test and asked, "Do you know how many stars there are in Kaiyang, the second star of the Big Dipper?" ”

Yue Muyun looked at Lida Phil in some surprise, and wondered, isn't Kaiyang Star just a star?

A star is a star, how can there be many?

Lu Zhengxing lowered his head and thought for a moment before saying: "I remember that there is a fainter auxiliary star next to a star, and in ancient times, people even used it to test the strength of a person, do you mean this star?" ”

"More than 70% of the star systems in the universe exist in the form of double stars, and about 25% are single stars. The rest is the triple star, the quadrupole star, in the universe like your solar system is too rare, most galaxies have a star with two or more stars, I just told you about the Kaiyang star, it should actually be a 7-star system, its main star Kaiyang star is a 5-star system, the auxiliary star you just mentioned is actually a two-star system. ”

Lu Zhengxing was startled when he heard this, it turned out that there were a total of 7 stars in this Kaiyang Star plus auxiliary stars, but due to the long distance, it looked like two stars.

From this, Lu Zhengxing thought of the legend of the ancient Oriental country in which Hou Yi shot the sun, at that time there were 10 suns in the sky, and Hou Yi shot 9 because it was too hot, so there was only one sun left in the solar system, could it be that the solar system could have had multiple stars before, and his idea suddenly aroused Mingjing's curiosity.

He also said what he thought, and asked if Lori had a star system.

It's a pity that Mingjing checked the information for a long time, and he didn't find any relevant records about 10 stars, maybe his database is still too small.

Lida Fil said with a smile: "This is actually entirely possible, when many stars gather together, their orbits will be very complex, the most typical example is like the orbit of three stars entwined, that is, it is too complex to calculate, not to mention 7 or even 10 stars, often only the movement of the binary star system is relatively regular, often also has a certain periodicity." ”

Lu Zhengxing said curiously: "For the planets in the system. Isn't it better to have more stars? ”

Lida Fil said with a smile: "There are many stars, and the situation is complicated due to various variables. Therefore, the real environment is simple and more conducive to survival, and it should be a single-star system. ”

This made Lu Zhengxing very comfortable to listen to, it turned out that the earth was still quite good, at least there was only one star in the solar system, and there were not so many messy and complicated situations.

Lu Zhengxing asked Ming Zhu to call up the topographic map of Kaiyang Mountain, and he was surprised to find that Kaiyang Mountain is actually surrounded by seven peaks, so Kaiyang Mountain is actually not just a mountain.

As the car got farther and farther away from Pojun Mountain, the roar of the ground gradually decreased. The surroundings are getting quieter again.

Little Lori put on a mecha and prepared a camera ready to go out to collect data.

Lu Zhengxing didn't go, he asked Qiongli to accompany Xiao Lori.

As a result, there were only three people left in the car: Lu Zhengxing, Yue Muyun, and Jiang Lin'er.

Yue Muyun Yue Muyun, seeing that Xiao Lori and Qiongli were gone, bowed down and said: "The prince is above, and he is worshiped by Yue Muyun......"

I don't know if I'm dizzy or not, what do I want to say next, but Lu Zhengxing hurriedly mixed her up.

Lu Zhengjing said sincerely: "Let's not engage in these vulgar etiquettes in the future, I will treat you as a friend and relative." ”

Yue Muyun was very moved when she heard this, her voice was a little choked, and she couldn't speak.

She was originally a maid in King Lu's mansion, and how could he not be moved by such respect from Mr. Lu?

Lu Zhengxing diverted the topic, and said to Yue Muyun: "During the time I left, are you okay in the car?" Has anything ever happened? ”

Yue Muyun said: "It's good that nothing happens......"

It's just that at this time, Jiang Lin'er inserted a sentence sourly: "Of course it's not good, I bullied your Yue Muyun, what can you do with me?" ”

Hearing this, the corners of Yue Muyun's eyes twitched.

Because she remembered that in the days when Lu Zhengxing left, Jiang Lin'er had a fearless and arrogant approach.

Lu Zhengxing noticed this change, he looked at Jiang Lin'er coldly and said, "If it weren't the end of the world at this time, I would definitely get you out of the car." ”

These words were very cold, without any emotion, and there was a trace of ruthlessness in Lu Zhengxing's eyes.

Jiang Lin'er's eyes were red, and her tears fell, but she turned her head sharply and hid in the corner of the carriage again, not wanting people to see him.

Seeing Jiang Lin'er like this, Yue Muyun sighed: "Actually, it's nothing, I'm fine, you don't have to worry." ”

To be honest, Yue Muyun is a little pitiful to Jiang Lin'er now, and Lu Zhengxing looked at Jiang Lin'er's appearance and regretted that what he said just now seemed to be a little too heavy.

But poor people often have something to hate, and the misfortunes experienced by many people cannot be said to have nothing to do with him, just like Jiang Lin'er at this moment.

The kitten Jixiang rolled over in Lu Zhengxing's arms, stretched his waist and continued to sleep.

He felt safe in Lu Zhengxing's arms, and he felt that the closer he was to Mingjing, the safer it was.

Lu Zhengxing was a little helpless, the cat had been sticking to himself since he got back into the car, and he didn't know why.

He discussed with Yue Muyun: "Can you give Jixiang a bath, look at what is going on here!" ”

Hearing this, Jixiang was reluctant to move, but Yue Muyun said, "The kitten is coming to take a bath, and I'll make you something good that you've never eaten!" ”

Hearing this, the kitten Jixiang was obediently taken away by Yue Muyun.

At this time, only Lu Zhengxing and Jiang Lin'er were left in the carriage, Jiang Lin'er said leisurely: "Lu Gongzi is not right, Lu Wangye ordered, you don't have to dislike me anymore, I will leave soon." ”

Hearing this, Lu Zhengxing looked at Jiang Lin'er in surprise and said, "It's so dangerous outside, where are you going?" ”
