However, the world is unpredictable, and just when Zhou Xin thought that the other party's harassment would only continue as it is now, the situation suddenly changed.

On this day, eight days have passed since the other side first began to attack frequently. Half an hour after the third alarm sounded today, the alarm that everyone had long been accustomed to sounded again.

"Brother Captain, Brother Captain." Along with the sound of the sirens came the sound of Atlas.

"Did the other party start attacking again?" Since Atlas had handled several alarms before and had not reported them, Zhou Xin was a little surprised to hear her report suddenly. However, he didn't pay too much attention to it, and said casually as usual, "Just let the probe retreat." ”

"The other party is here to attack us, but this time they are not in the same place where they have been harassing." Before Zhou Xin's words fell, the little girl replied with a slightly anxious tone.

This answer really surprised Zhou Xin, he was slightly stunned, and then confirmed: "Not the original place?" At this time, not only him, but everyone in the command module was also attracted by Atlas's answer.

"Hmm." The little girl nodded heavily, "The ruins of another town we are investigating have been attacked, and judging by the appearance, this group of attackers should belong to the same force as the previous attackers. As she spoke, she showed the screen what the probe had captured.

Zhou Xin found that in today's picture, what can be seen is actually not much different from before, the same oval cylinder is attacking, and at the same time, the detector that is within the opponent's attack range is escaping. Perhaps the only difference is that the number of attackers is relatively small, only a dozen. But even so, the performance advantage still puts a large number of detectors at a disadvantage.

Not long after the screen appeared, the opponent began to turn around, and soon, even the attack stopped. After a few minutes, their figures grew smaller and smaller, and finally they were gradually swallowed up by the dim sea.

Compared with the losses suffered in the attack, Zhou Xin was obviously more concerned about the position of the other party. He looked at the screen and asked, "Where did they appear?" How far is it from the town they've been attacking before? ”

"They attacked a very ordinary town this time." Atlas replied, "The distance between it and the ruins of the town that has been under attack is about two thousand kilometers or so. After saying that, she added in a puzzled tone, "What makes people feel strange is that there are still three or four town ruins between the two attacked towns, but the other party did not choose them, but chose the ruins in the picture far away." In the previous investigation, people didn't find anything special about it. ”

The little girl's words made everyone wonder, however, in the current situation, there was no way for them to figure out each other's intentions. Even Zhou Xin could only reluctantly order the detectors in various places to strengthen their vigilance, and at the same time step up the time to investigate.

"I don't think it's over yet." After Zhou Xin's order, Dart said with a solemn look, "Since they can attack the ruins of the second town, it means that they can also attack more places. ”

"So what can we do?" Zhou Xin smiled bitterly and continued, "The underwater technology is not as good as theirs, what can you do besides keeping the detector vigilant at all times?" Is it a complete withdrawal from the investigation of this planet? ”

"No, no, you misunderstood, the key issue is not the loss of the detector." Dart shook his head, "What I care about is what happens if our mining team is discovered by the other party if this continues." ”

Hearing this, Zhou Xin suddenly fell into silence, and after a while, he let out a long sigh, "Now we can only take one step at a time, I hope the other party will not find out about our mining team." ”

However, it is important to know that sometimes the more undesirable a situation is, the more likely it is to happen. Only one day had passed, and Zhou Xin and the others received the news that the third ruin had been attacked.

In the days that followed, it was like a plague spreading, and many places were hit by similar attacks. However, what made Zhou Xin and the others even more puzzled was that after a long period of observation and analysis, even Atlas did not find any pattern in the frequent attacks of the other party. Because sometimes two attacks in a row take place in two ruins that are very close to each other, but sometimes they take place in the ruins that are far apart.

When the two consecutive attacks occurred at almost opposite ends of the planet, Zhou Xin finally couldn't help it, "How did the other party's underwater speed allow them to reach the other side of the planet in such a short time?" ”

"The facts are right in front of our eyes." Dart continued, "All that is said is that they must have a way to do this." He then pointed to the map of the attacks on the screen and said, "But that's not the point, you see, the attack is less than 500 kilometers away from our mining site in a straight line." If this continues, I'm afraid it won't be long before they discover this place. Let's think about whether there is any solution. ”

"What can be done?" Zhou Xin said helplessly, "If the mining site is on land, we can also set up some defensive measures around. But now we have to work underwater, which is not what we are good at. Even if you send the combat robots down, I'm afraid it won't be very useful. Speaking of this, he sighed, "If they find out then, I'm afraid we will have to choose another collection point." ”

Regarding Zhou Xin's statement, everyone also felt a little helpless. Just when they didn't know what to answer, Atlas's voice suddenly rang out.

"Brother Captain, Brother Captain, people - it seems that something special has been discovered." There was a hint of strangeness in her voice in excitement, and at the same time some hesitation.

The little girl's words interrupted everyone's train of thought at once, and at the same time made Zhou Xin's attention focus on her, and he asked curiously, "Why is your expression so strange?" Tell me, what ...... discovered? ”
