"Hey, mom, I won't go back for the New Year this year... Yes, I have an urgent matter, I'll take time to go back after the New Year... OK, I'll take your daughter-in-law back then and I won't forget..."

The end of the year is approaching, and with the approaching of the alien warship, it is obvious that Lu Yi cannot have free time during the New Year.

Amid Lu's complaints and Lu's father stopped Lu's mother, Lu Yi hung up the phone, reached out to rub his eyebrows, and continued to check the data on the screen.

Now the warship has crossed the orbit of Pluto, and its target seems to be heading to Jupiter, but at this time the warship, Jupiter and Earth are on the same line, and no one can be sure that the other party is not coming to Earth.

"What did this happen? Could it be that the war was really damaged by the warship and had to enter the solar system to repair the spacecraft. However, the damage surface did not seem to be caused by mass guns, but it was a bit like a meteorite crashing."

Lu Yi looked through the latest images of the warship. When the other party crossed the Kuiper Belt and entered the solar system, the dust and meteorites of the Kuiper Belt were missing, and the other party's traces were completely exposed to human sight.

What surprised humans was that it was not a fully armed warship that entered the solar system, but a broken warship.

Not only Lu Yi was unexpected, but everyone was a little surprised. This also caused the other party to be not war, but to cultivate and exchange peacefully.

"Is it really here to repair the warships, not malicious?"

An idea emerged in Lu Yi's mind, opening up the image information that had been captured by the warship before, especially after the other party sent out active detection.

"Is this?"

Suddenly, two abnormal pixels on an image attracted Lu Yi's attention.

According to calculations, this is an item with a diameter of about 30 cm. It is only at such a long distance scale. Even if the most advanced scanning detection array is used, the item has only two pixel points in the image.

Such pixel points are generally classified as useless information during detection because they are too small and too blurry.

And it is within the Kuiper Belt, with dust everywhere in the starry sky, which is a burial ground for meteorites. Therefore, even if the detector sees it, he will subconsciously ignore it, thinking that it is the gathering of dust or small meteorites in the Kuiper Belt.

Lu Yi had some obsessive-compulsive disorder, so he retrieved all the historical images in this direction, and after comparison, he found that these pixels did not appear in the previous scanned image.

"What the other party threw down? Or the meteorite that was covered before?"

Lu Yi, who felt that he had discovered something, calculated the speed and channel of the unknown item based on only 4 images that scanned the abnormal item, based on the scanning time of the image, and the direction of the item changes when the scan was discovered.

"The speed is about 60 meters to 200 meters per second. At this speed, most meteorites in the Kuiper belt do not have much difference in speed, but this orbit..."

Lu Yi looked at the calculated orbit. If there was no collision, the orbit of this item was similar to that of most comets, and they were both an elliptical shape.

However, Lu Yi retrieved the previous scanned image based on this track, but did not find this item on this track path.

"In this case, then this unknown item is likely to be thrown by this warship, so it's very interesting."

Lu Yi kept thinking about it. During the interstellar voyage, any part of matter is precious and will not be thrown away like on earth. Instead, it will be reused after use.

Even if it is feces and urine, it will be collected, and then the substances and elements inside will be reclassified and reused.

During the interstellar voyage, it is likely that the water you drink is actually the feces or urine that you pulled 5 minutes ago.

It's okay to throw it, but the initial force and angle of this throw are obviously strictly calculated, and are thrown out based on the speed and orbit of most meteorite comets in the solar system.

"The other party is deliberately covering up the thrown item!"

After thinking for a while, Lu Yi affirmed his guess. If the force and angle thrown out were not strictly calculated, it could be said that the loose parts of the opponent's battleship were knocked down by a small meteorite.

But if you throw it out after strict calculations, it is undoubtedly certain that the other party was deliberately concealing something.

If there hadn't been a chance to find the other party's trace before that, and had already established a large scanning and detection array on the moon, space orbit, and on the ground, it would have been impossible to scan this small object with a diameter of less than 30 cm.

If the other party's active detection behavior was discovered at that time and did not use all scanning arrays to track it as soon as possible, even if it was discovered later, it would not have been linked to the alien warship with the object that was not different from the meteorite comet.

"Commander Lu, there is an update, and the other party actively emits electromagnetic waves to communicate!"

While Lu Yi continued to guess the other party's purpose, a staff member suddenly rushed over to report to him.

"Teacher actively?" Lu Yi's eyes narrowed slightly, he saved his analysis results, and quickly stood up and walked inside.

"What's going on now?"

Walking inside, all the people were busy. Lu Yi looked at the information on the big screen and asked Lao Su.

"Five minutes ago, the other party launched a large laser screen panel, and the information was flashing repeatedly on it. Through preliminary analysis, the information belonged to the language dictionary."

Lao Su hurriedly replied that the 5 minutes here refer to the time when the laser screen was detected, rather than the time when the alien warship actually launched the laser screen panel.

According to the speed of light, the other party has just crossed Pluto and is nearly 4 lights away from the earth. The actual time to launch the laser screen should be 4 hours ago.

This is just like the sunlight seen on Earth, which is actually emitted by the sun 8 minutes ago.

Lu Yi nodded and did not disturb him again. He was not an information expert, and Lao Su could only count half of it. If he really wanted to decrypt the language dictionary sent by the other party, the group of scientists with a little cold scalp in front of him were.

Half an hour later, Professor Hill took a tablet and handed it to Lu Yi and said, "It's a language dictionary, but it's just a language dictionary that has been processed. There is not much valuable information on it."

A language, a word, and the meaning contained in every pronunciation and every symbol is given by wisdom and life. If others want to understand their own language, they must tell the other party about the meaning given to each pronunciation and symbol.

That is to say, a complete language dictionary. In addition to the content of various languages ​​and characters, these contents must also be matched with images before they can be used.

For example, in human Chinese, I write two Chinese words "Sun" and let others guess the meaning. Except for those who have learned Chinese, others, including aliens, will be foolish when they see it.

But if you write the word "sun" and then draw an image of the sun next to it, others will understand it, and even after further proficiency, you can directly use "sun" to express it.

This process of giving meaning to the pronunciation language can reveal a lot of information about this civilization. The general form of life in this civilization can be derived from some word explanations, the general system of this civilization can be known from some noun explanations, and even the scientific and technological level of this civilization can be known from some words.

But unfortunately, the language dictionary sent by this alien warship has been analyzed and is obviously a processed dictionary, and the civilization information that can be disclosed on it is almost equal to 0.

Lu Yi pondered for a moment and ordered: "Send communications in the other party's language dictionary, ask the other party to explain the purpose of entering the solar system, and ask the other party not to cross the orbit of Jupiter!"

Jupiter's orbit is 630 million kilometers away from the Earth. At such a long distance, coupled with the interstellar dust permeated by the asteroid belt, even high-energy light weapons will attenuate most of their energy, thus unable to pose too much threat to the Earth.

As for mass guns, although the actual energy decay in space is very low, the mass bomb speed can be scanned in advance and discovered at the speed of light. Humans will have enough reaction time to intercept at such a long distance.

"yes."

A technician next to him responded, and Hill nodded in agreement with Lu Yi's proposal, which is the safest choice for humans.

drop.....

Before the technician could edit the communication based on the other party's language dictionary, the radio scanning array in space detected a regular electromagnetic wave.

The information of the electromagnetic wave is not encrypted, and the system automatically matches the information and matches the other party's language dictionary to display the information contained in this section of electromagnetic wave.

[Dear civilization, hello, we are the communication ship of the Qinglan civilization.

When we were sailing interstellar, we collided with interstellar stray meteorites at high speed in outer galaxy space due to a detection system failure, resulting in serious damage to the AC ship. We hope to replenish matter and stay in your galaxy for a period of time to repair the hull. In exchange, we can use some scientific and technological data as rewards.]

Everyone in the entire hall stopped their movements, looked at the first alien civilization communication in human history, and then turned their eyes to Lu Yi.
