"What are they trying to do?" Seeing the other party's actions, Zhou Xin couldn't help but get nervous again, "Is this posture about preparing to attack us?" Then he subconsciously ordered, "Voyager, let the battle robots be ready for battle at any time." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 But then he added, "Don't attack yourself, see what the other party does next." ”

At this time, he had already seen the dozen or so people who came out of the hovercar, and as soon as those people appeared, they walked towards the signal transmitter, and correspondingly, a few people came out of the signal transmitter to greet them.

Soon, the two groups met. Next, they stood at a distance of about a meter and looked at each other. Judging from the faces and movements of both of them, it is not difficult to guess that they are communicating at this time.

At the beginning, the two sides were just communicating normally, and their movements and expressions did not change much. But in a short period of time, that has changed. Zhou Xin saw that among the group of people who got off the hovercar, the expressions of several people suddenly became excited, and one of them even stretched out his hand and pointed at another group of people, with an expression on his face that looked like he was accusing each other. The strange thing is that the wave of people who came out of the aircraft did not respond with the same emotion, and many people showed helpless looks on their faces.

After this situation continued for a while, the people who were already very excited seemed to be even more excited, and they couldn't help but wave their hands in excitement. Suddenly, one of them turned backwards, apparently trying to walk back into the hovercar. Seeing this, another group of people hurriedly took a few steps forward, looking like they wanted to hold the person but didn't dare to pull it. The man who turned around had just taken a step back when the calmer-looking man next to him grabbed him. Immediately afterwards, the person who grabbed him showed a serious expression on his face, and after a stalemate for a while, the faces of those who were originally very excited eased. Another few minutes passed, and the two sides seemed to have reached an agreement, and a few people on the other side of the aircraft turned around and walked towards the signal transmitter with the group of people who had come out of the hovercar. Seeing this scene, I don't know why, Zhou Xinxin suddenly had a feeling as if he had escaped.

Although the mood has relaxed slightly, with the arrival of a new group of people, the surrounding situation has suddenly become more tense and complicated. The airspace around the Voyager had subdued down the aircraft, and they began to fly around the ship again, hovering quietly outside the warning range, and frequently rushed into the designated warning area. Although they would still fly out after encountering the probe's block, Zhou Xin still felt that the attitude of those flying machines seemed to be different from before. However, because the other party did not make more drastic moves, Zhou Xin did not respond to this fiercely, but just ordered the detector to strengthen vigilance.

Another ten minutes passed, and the other party did not make any other moves except for the slightly abnormal aircraft. Just when many people thought that nothing should happen for the time being, Atlas's excited voice suddenly sounded in the command cabin, "Brother Captain, I just received a recognizable signal from the other party. Hearing this, everyone in the command cabin couldn't help but get excited.

"Can you finally get in touch?" Zhou Xin asked with a relieved tone. However, the little girl's next stroke made him feel extremely disappointed, "The content of the signal is-huh? Isn't this just the contact signal that people sent before? The content is exactly the same as what they send, and even the waveform of the signal is exactly the same. Then there was a pause for a few minutes before she spoke again, "Brother Captain, the other party is now sending us a contact signal that we sent at the beginning in a loop as it is. ”

"What did they want to do by sending us the signal back to us?" Zhou Xin asked puzzled, "Do they understand what we mean?" This question made many people present have puzzled looks on their faces.

It thought for a long time, and then Spred replied in an uncertain tone, "I think - the other side may not understand what we are trying to say in the signal, or they wouldn't have sent the signal back as it is." After a pause before Zhou Xin could ask a question, he continued, "But although it is highly likely that they do not know the meaning of the signal now, this practice has revealed to us a message - that is, the other party has received the contact signal we sent. ”

"That is." Spred's reminder made Zhou Xin understand at once, "The other party received the signal we sent, but he didn't understand what the signal was trying to say. And in order for us to know this, he can't reply with his own signal, because then we can't understand it. So they intercepted a piece of the signal we sent and sent it back to us? This is a bit awkward, but the logic is relatively clear. As soon as Zhou Xin finished speaking, many people understood the meaning.

"That's it." Spred nodded.

"Since the other side has responded in this way, it is natural to expect us to react in the same way. At the very least, you can know that your previous efforts have not been in vain. After understanding this, Zhou Xin thought about it, and soon he ordered, "Atlas, like them, intercept a signal sent by the other party before and send it back to them." ”

A few seconds later, the little girl followed Zhou Xin's instructions and sent the signal out. After less than a minute, they got the other party's response again, "Brother Captain, the other party has responded to us with a new series of signals, which are also intercepted from the contact signals we sent to the other party before. ”

This time, there was no need for Spred's reminder, everyone understood. The meaning of this signal is "We already know." ”

"This also shows that the wisdom of the other party should be at least on the same level as ours." After receiving the response again, Spred added, "Otherwise, it is unlikely that we will be able to guess the meaning of each other's series of actions during this time." ”

For a long time afterward, the two sides resumed sending their own communication signals. But there's one more step - every half hour or so, Atlas receives a snippet of a signal from herself during that time. In response, Atlas will also intercept a signal sent by the other party and send it back, and so on. Unfortunately, that's all the two sides can do now. They still can't understand even the simplest word in the signal they are sending......
