Two years later, the expeditionary force captured a radio wave again, and the frequency and band of this electromagnetic wave signal, and even the propagation speed were exactly the same as the previous radio wave!!

If the scientific team of the expeditionary force is not completely convinced that it is an unknown cosmic civilization that sent the signal before receiving the second radio signal, then after capturing the second radio signal, the existence of the unknown cosmic civilization can be completely confirmed.

In the Central Command Center of the Expeditionary Force Fleet.

“@#￥#%%@#￥#%%@#@#￥#￥@！ #@￥#￥#@#￥@#￥#￥......”

"This radio wave signal has more obvious traces of intelligent civilization information transmission. The duration lasts 45.1 seconds, with two distinct repeating bands, and 3 reused fields that are logically related to the message, probably similar to prepositions in our language. ”

Don Quixote, the scientific commander who had been in contact with the electromagnetic wave signal first, analyzed it to Hara Haochen.

"Don Quixote, Sergey, this time we can completely rule out the possibility that the signal came from some special pulsar or other celestial body!" Yuan Haochen looked at the two senior commanders beside him and said expressionlessly.

"Yes, Leader, that's an unknown cosmic civilization!"

"Moreover, the other party is at least an advanced stellar civilization."

Sergey and Don Quixote replied.

"What does it mean to be able to capture two electromagnetic signals in a row at such a long distance!?" Yuan Haochen asked and replied, "Behind the two accidental events is an inevitable result. There must be a lot of signals that are transmitted in this direction of the fleet, otherwise in the vast universe, how can we capture two radio waves in a row!! ”

"What do you mean, the unknown cosmic civilization ahead is very likely to be a huge group, and even the galaxy where their civilization was born is ahead!" Don Quixote asked softly.

"That's not going to be easy!!" Before Yuan Haochen could speak, Sergei's loud voice rang out first, "If the other party is a whole galaxy, then the strength of the expeditionary fleet will definitely be incomparable!" ”

"Sergey, this is not the worst." Yuan Haochen stared at Sergei and said with a straight face, "Maybe it's not just one star system, the other party's forces must cover many star systems in front of you." ”

"Yes! As an advanced stellar civilization, they must have mastered and developed the surrounding star system. Just like us, we will soon be adding the star system around the Sunrise galaxy to our map. Sergei looked grim and said thoughtfully, "So it seems that we have to go around these star systems in a big circle......

"Tesla!!" Yuan Haochen looked at the panoramic simulated star map in the command center, and suddenly asked Tesla, the commander of the engineering department, who had been standing silently behind him.

"Ah, Leader, I'm here." Tesla seemed to be wandering and suddenly woke up.

"You've already calculated the distance and direction of the signal source and the fleet this time." Yuan Haochen asked with a chuckle.

"Well, that's true." Tesla stepped forward and pointed to the star map to introduce to everyone, "According to the strength and attenuation of the signal this time, we roughly judged that the distance between the signal and the expeditionary fleet is 60~100 light years. In addition, combined with the propagation range of the two signals, we have obtained a crossover area, and if nothing else, this unknown cosmic civilization should exist within +-10.2 ° in front of the fleet's route. ”

And so it was! We're really going to dive headfirst into each other's lair! Yuan Haochen raised his eyebrows, and then analyzed with a serious face, "Two years ago, Tesla speculated that the signal source was about 80~120 light years away from the fleet. According to the speed of the fleet, after two years, the fleet advanced about 17 light years. Today, we are about 60~100 light-years away from the source, which means that the source has not moved in the past two years. ”

"Both of these radio signals are coming from some or some star system in front of us!!" This result made Don Quixote's eyes widen.

"So, in 6~10 years, we will cross the territory of an unknown high-level star civilization!?"

Although there has been such speculation for a long time, after the final decision, everyone is still stunned.

"As the fleet continues to advance, the scientific team must focus on observing and analyzing all star systems within 150 light-years of the fleet's front, and I need a detailed assessment report." Yuan Haochen ordered the scientific commander Don Quixote, of course, this work takes time, and it is difficult to observe the inside of the star system at such a distance.

"Yes, Leader!!" Don Quixote replied with a cautious expression.

"Where is the Phantom Recon fleet at the moment?" Yuan asked the military commander Sergei again.

"Here!" Sergei waved his right hand forward, and a column of light spots instantly appeared on the simulated star map, "About 4 light-years in front of the fleet, it continues to fly forward at high speed." ”

"We must always pay attention to one point, and we must not send any faster-than-light signals to the reconnaissance ship, in case the signals transmitted forward are intercepted by the other side and cause unnecessary trouble." Yuan Haochen confessed to Sergei.

"Please rest assured, according to the agreement at the time of departure, the Phantom reconnaissance ship has been in continuous one-way communication with the fleet, and if there is any trouble, the reconnaissance ship will report to us as soon as possible." Sergey replied.

"Good! After five or six years, all this should be clear, and I hope that everything will go well for the operations of the reconnaissance fleet!! Yuan Haochen nodded and said.

......

At present, the entire expeditionary force fleet is still about 80 light-years away from the unknown cosmic civilization ahead.

With such a distance scale, there is still a lot of room for the expeditionary force to make operational decisions.

In this vast cosmic space, at such a long distance, it is absolutely impossible for the expeditionary force to determine the specific location of this unknown civilization and to discover the planets in the galaxy ahead. Similarly, as long as the expeditionary force fleet does not make a big move, but only maintains a normal flight state, it is also a fantasy for the other party to want to discover the expeditionary force.

After discussions, all the senior leaders of the expeditionary force unanimously decided that the main body of the fleet would continue to fly on a straight course and make further decisions based on the intelligence snooped on by the Phantom reconnaissance ship in the future.

Whether to drastically change course or make contact with the civilization of the unknown universe (including friendly communication and warfare) will be decided by the expeditionary force within the last 10 light-years.
