"You know, the location where those attackers appeared is the deep sea, such a clear place, why don't we investigate it first?" Zhou Xin said, "Maybe the control center we have been looking for is not within the search range of the current probe, but is hidden in the deep sea." Of course, I don't expect to find any control centers there, but I should always have some connection with them in the places where they gather. At least to be able to find more clues is much better than searching aimlessly like we do now, isn't it? ”

After listening to Zhou Xin's analysis, many people, including Spred and Dart, suddenly woke up like a dream, and Spred patted his head in annoyance and said, "Yes, why didn't I think of it?" Why didn't you think of it? ”

"It's not your fault." Zhou Xin explained in a calm tone, "Although we discussed the deep sea at the beginning, because of the special circumstances at that time, I did not order to continue the in-depth investigation. Seeing that everyone nodded repeatedly, he continued, "Although the situation has changed since then, we are obsessed with finding the control center in the ruins of the town, and at the same time, our attention has been distracted by the attacks of the other side in various places, so we have not considered the problem of investigating the deep sea again. As he spoke, Zhou Xin subconsciously glanced at the screen, "Actually, if Atlas hadn't just mentioned the deep sea, I wouldn't have thought of this." ”

"But, Brother Captain." However, at this time, Atlas's opposing voice sounded in Zhou Xin's ears, "Even if you think about it now, you can't do it." You know, the extent of the deep ocean is actually much larger than all the areas we're investigating today combined. Since we don't have any discoveries yet, what can we find in the much larger depths of the ocean? And, if a comprehensive survey of the deep sea were to be conducted, wouldn't it be as clear as it is now? Not only the little girl, but the others also showed puzzled expressions on their faces when they heard this objection.

"Of course I do." Zhou Xin continued, "So I'm not going to let the probe conduct a comprehensive exploration of the entire deep sea range. ”

"What if we don't conduct a full investigation?" The little girl continued, "Is there a local investigation?" But if we are conducting a local survey, how do we delineate the scope of the survey, is it a random choice? ”

"Obviously, you can't just choose that way." Zhou Xin shook his head, and his next words were even more confusing, "Of course, it's not up to any of us to choose, but on them. As he spoke, his gaze turned to the big screen.

Seeing Zhou Xin's movements, Spred seemed to understand something after thinking for a short time, and he said, "What do you mean - those attackers?" ”

"Hmm." Zhou Xin nodded, "We have been obsessed with looking for clues in the ruins before, but in fact, we forgot that the other party's whereabouts themselves are a very important clue. Of course, it can't be said that we have forgotten, mainly because our detectors can't catch up with them at all. However, since we can't find any better clue now, we have no choice but to use it for now. ”

"Follow the retreating raiders, find their gathering place in the deep sea, and then investigate the gathering place?" Spred summed up Zhou Xin's thoughts in one sentence, and then he struck mercilessly, "In theory, this idea is very good. But have you ever considered that our probes couldn't keep up with them before, so do you expect them to be able to keep up with the attackers now? If we can't keep up, how can we talk about follow-up investigations? ”

"At least it's a clearer goal, more reliable than the aimless search we have on the planet like we do now." Zhou Xin replied, "Moreover, now I just put forward an idea first, and as for how to do it, we need to discuss it next." ”

"Okay." Spred shrugged, "In that case, my first question is this—what are we going to do to catch up with the retreating attackers?" ”

Hearing this question, many people present subconsciously shook their heads with puzzled expressions, and Dart even smiled bitterly and said: "If we can think of a way, we have already figured it out in the previous discussion, why wait until now." Even Zhou Xin himself shook his head with a helpless look.

Seeing everyone's reaction, Spred sighed, "It would be nice if the speed of the probes could keep up with each other." ”

"Otherwise, we'll take some time to build a special equipment for underwater." Zhou Xin thought for a moment and made his own suggestion, "In this case, we should be able to barely keep up with each other in terms of speed, but if we want to do this, it will take about a week to manufacture." ”

"Now it looks like we'll only have to wait a week." Spred said.

"Waiting for a week isn't a big deal." Dart continued, "But have you ever thought about how to deal with the attack? Now it is possible to determine that our underwater detection equipment is inferior to those attackers. In other words, even if we can keep up, if we want to track, we can only swagger into the other person's field of vision. Those programs aren't stupid enough to be indifferent to a tail. ”

"This-" Zhou Xin didn't think about how to answer this question for the first time, he could only say ambiguously, "This-I should be able to think of a way at that time." ”

"Actually—" Atlas said with hesitation at this time, "they have thought of a solution." It doesn't take much preparation time, but it's a bit more cumbersome. ”

"What's the solution?" Now Zhou Xin couldn't think of a better way, so he didn't pay attention to the trouble mentioned in the little girl's words at all, but asked in an eager tone. Spred also answered, "Don't worry about the trouble first, you can speak up and listen to it first." ”

"Hmm." The little girl nodded, and then began to explain her thoughts, "Actually, after observing so many attacks that have occurred so far, people have found that the direction of retreat chosen by those attackers is relatively fixed. In that case, why don't we use relay tracking? ”

"Relay tracking?" Although Zhou Xin got some inspiration after hearing this word, he didn't fully understand the key in a short period of time, so he asked, "What do you want to do......?" ”
