"If you leave, it will further affect the progress of the Voyager's maintenance, and then form a vicious circle." Atlas said.

"Or, evacuate all the robots, probes and other equipment related to us on the planet for the time being, and wait until the activities of those attackers have weakened or even disappeared before going back to continue our work?" At this time, another voice said.

"If you're going to do that, you don't know how long you'll have to wait." Zhou Xin said helplessly, "Moreover, now our large-scale operation on the planet has obviously aroused the vigilance of the other party, even if they can temporarily disappear from our field of vision, but we don't know when they will be rediscovered when we return to the planet again." For us, it's just too passive. Saying that, Zhou Xin sighed, "Forget it, use this as a backup plan." If you really can't think of a better way, and the situation on the planet worsens, then you can only do it for the time being. ”

"In this case, the best thing to do is to find the other party's control center." "I'm afraid nothing else can solve their problems once and for all." ”

"But where the hell is that damn control center?" Dart's voice looked a little irritated, "How could we possibly find it on such a large planet without any clues." ”

Dart's words caused the command module to fall silent again, and after a while, Zhou Xin said in a tone without confidence: "Then we can only let the probe continue to investigate on the planet, maybe we will find clues in the next moment." ”

Time passed quickly, and another few days passed. In the past few days, a large number of probes on the planet are still carrying out their own investigations according to the previous plan, and they also have to prepare for attacks from time to time, so it can be said that everything is basically the same as a few days ago. The only thing that surprised Zhou Xin and them was that after the mining site on the planet was discovered by the attackers, except for the first small harassment, in the following days, the other party never appeared again, which couldn't help but make many people feel quite puzzled.

"Strange, how the hell do they judge?" On the sixth day of the attack on the mining site, Zhou Xin finally couldn't help but ask, "I obviously found out where we were mining, but why did we avoid that place during the attack?" ”

"This may be a problem in the judgment of the program designed by the other party." Spred speculated, "Maybe the program didn't think it was a place of interest at all, so it ignored it." Then he spoke with a hint of glee, "Anyway, it's at least a good thing for us." ”

"I don't think so." Dart, however, was not as optimistic as Spred thought, and said, "Maybe the other party thinks that place is quite important, so they are preparing a larger attack behind it, and it is unknown that they want to destroy our mining site at once." ”

"Either way, we can't let our guard down." Zhou Xin did not express his opinion, but instructed Atlas, "Let the probes and combat robots around the mining site expand the patrol range, so that even if the other party appears on a large scale, we will have enough time to react." After giving the order, he then asked, "During the investigation in the past few days, has the probe found any clues?" ”

"Nope." The little girl on the screen shook her head helplessly, "In addition to the wreckage or wreckage, what can be found is not only that, but even the other party's activities around the planet also do not see any patterns." ”

"Strange, where the hell is the control center?" Zhou Xin frowned and fell into deep thought.

"Didn't you even find any special signals?" While Zhou Xin was thinking, Spred suddenly remembered a question, "Since the control center can control those attackers, then it should always send some control signals to them." ”

"Hmm-" Atlas looked hesitant when she heard the question, and after a moment she replied, "The probe did pick up a small number of strange signals, but after confirming the source of the signal, it was discovered that all of those strange signals came from the deep sea. At the same time, the strength of the signal itself is quite weak, and it is more like a biological signal than something emitted by some kind of device. Therefore, it is judged that the source of these strange signals may be some special creature on the bottom of the sea, or the echo formed by the signal emitted by our detector after it touches the deep seabed. ”

"Deep Sea?" At this time, a word in the little girl's words caught the attention of the contemplative Zhou Xin, and he subconsciously repeated, "Deep sea—is it——? After repeating it a few times, he once again fell into a new round of contemplation with his chin propped up.

Although the voice was not loud, Zhou Xin's self-talk still attracted the attention of some people around him, and Dart asked directly: "What's wrong with the bottom of the sea?" What do you think of? However, Zhou Xin, who was thinking about it at this time, did not pay attention to Dart's question.

More than ten minutes passed, and when many people noticed Zhou Xin's strange performance and focused their eyes on him, Zhou Xin slowly spoke: "I think - all along, our thinking has been drilled into the tip of the bull's horns? ”

"Horn tip? What horn tip? Before Zhou Xin's words were finished, Dart hurriedly asked.

"Nowadays, we are obsessed with finding the control center on the planet, isn't this the tip of the horns?" Zhou Xin replied.

"Do you want to give up looking for the control center, but if you can't find it, then how can we stop the attack?" Dart asked.

"I don't mean to give up looking." "It's that we're so obsessed with finding the control center that we ignore other things. Since we can't find the control center on the huge planet for a while, and we can't find any clues related to the control center, why don't we change to a more definite target to investigate? ”

"A different target?" At this point, even Spred's interest was raised, "What kind of investigation target do you want to change?" ”

"Under the sea." Zhou Xin said the word he had been repeating just now, and then he continued, "Deep Sea, to be exact. You know, the location where those attackers appeared is the deep sea, such a clear place, why don't we investigate it first......? ”
