Early morning.

The awakening camp gradually became lively, and people wearing different colors of overalls gathered at the food distribution point one after another to receive compressed dry food for breakfast, and then took the dry food and walked to their construction site according to the assigned type of work.

Crowds of different colors dispersed after passing through the food distribution point, and people wearing the same color clothing walked in the same direction, red to red, blue to blue, without a trace of variegation.

It's a spectacular sight.

However, Chen Zheng had long been familiar with such a scene, he poured some salt on the toothbrush, and then stood in front of the public sink with a wooden cup in his left hand and a wooden-handled toothbrush in his right hand, trying to clean his mouth.

"My lord, the director is looking for you." George's voice sounded behind Chen Zheng.

"Gollum...... Phew......" Chen Zheng rinsed his mouth, spit out the waste water in his mouth, and turned around to come to his senses, "It's good to send an email, why bother...... He didn't say anything? ”

"Nope." George shook his head.

"Oh, I see." Chen requisitioned his mouth with the towel on his shoulder, and then came to the main tent with toiletries.

At this time, a group of people were gathered around the glasses, they were discussing something, and they didn't notice Chen Zheng coming in.

"I heard you were looking for me?" Chen Zheng casually put the wooden cup containing the toothbrush and salt box on the computer desk, and separated the crowd and came to the man with glasses.

"Yes." The man with glasses nodded and called up a video: "You must see this." ”

Shown in the projection is a video of an excavation.

Several agents were busy operating the machine, and judging from the footage, the location they were digging in was supposed to be the same level where the mother worm once lived.

They dug and dug when suddenly a wall collapsed in a tremor, revealing a dark hole.

Several agents looked at each other, carefully threw down the digging machine, and tiptoed away from the excavation site - according to Chen Zheng's orders, anything strange was to be removed as soon as possible.

On the one hand, this is to ensure that zero crystals and various valuable things are not coveted by individuals, and on the other hand, it is also to ensure the personal safety of excavation personnel.

Although it seems that the entire canyon is not in danger anymore, no one knows if those hateful bugs still have a hidden backhand.

On this isolated planet, every human being is the most precious resource, and there is no way to replenish it if it causes casualties.

When everyone is gone, the video ends.

However, the man with glasses did not turn off the projection, but magnified the dark hole countless times, until the marks on the ground were clearly visible, and then pointed to a certain place and said:

"Look here, my lord."

On the ground at the entrance of the cave, there is a clear line of footprints, which stretch into the invisible darkness.

“…… Have you compared it to the previous footprints? Chen Zheng looked at the footprints and was silent for a while, then turned his head and asked.

"I've compared it, here's the information." The man with glasses called up the footprints found by the robot in the mural cave before the mother worm exploded, adjusted the two footprints to the same screen, and then listed a series of comparative data.

“…… Is it the same person? Chen Zheng asked hesitantly.

"It's more than 90 percent likely." The man with glasses has always been very strict in this kind of matter - he never makes absolute judgments.

"It's a black-skinned footprint, right?" Chen Zheng said the greatest possibility.

"We don't have any information on the footprints of the black skin, but judging by the size, size and depth of the footprints, the person who left the footprints is not much different from the body size of the black skin." The man with glasses pushed his glasses.

"Looks like I'll have to go again......" Chen Zheng muttered to himself, looking at the footprints on the ground.

……

Early the next morning.

A snowmobile stopped at the edge of the canyon, and the agents who had been waiting for a long time gathered at the side of the snowmobile and began to collect their breakfast.

Chen Zheng, the glasses man, and several of his recently trained human assistants jumped from the other side of the snowmobile, came to the snow plow behind them, and began to unload the vehicle.

The snow plough is equipped with a cleaner, an explorer, and associated control equipment and a tent.

An hour later.

The tent has been erected, and the robot and equipment have been debugged and placed in the hole behind the mother.

"Let's get started."

As everyone stares at the screen, the two robots begin a new adventure again.

"Wait, a little to the left, zoom in...... Stop. ”

Following Chen Zheng's order, the explorer's screen stayed on the cave wall, and through the enlarged picture, it can be seen that the cave wall is full of neat and regular tooth marks.

"This is the trace left by the pit worm before, exactly the same." After the man with glasses noticed Chen Zheng's gaze, he hurriedly explained.

"I see...... He's already run away from behind him. Chen Zheng frowned, "Strange...... How does it feel that his status is higher than that of the mother worm?? He's just an infected!? ”

The man with glasses was also silent.

"Unless ......"

Chen Zheng and the glasses man's eyes suddenly met, and they thought of a possibility at the same time:

"Unless he's carrying something more important than the mother!"

“……”

Having come to this conclusion, the entire tent fell silent.

What could be more important than a mother?

King worm larvae?

Or is it something more important?

No matter what the black skin took away, Chen Zheng and they all fell into strategic passivity.

As the saying goes, if you are not afraid of thieves stealing, you are afraid of thieves, only a thousand days of thieves and no thousand days of thieves, the things taken away by the black skin are like a time bomb, but Chen Zheng and they don't know where this bomb is, and they don't know when it will explode.

"......" Chen Zheng was silent, and he didn't know what he was thinking. The air in the entire tent seemed to freeze.

"That...... I have some ideas. A man at the console raised his hand, he was one of the few assistants that the eyed man had recently received.

Chen Zheng looked down and saw that he still knew this person - he was the Chinese who had gone down with Chen Zheng to explore the way before, the young agent named Zhang Chao under Lao Wang.

"Oh, you say." Chen Zheng nodded encouragingly.

"I guess the threat we face in the future should still be dominated by the 'dragon' of that day, right? After all, that's what it says on the mural......" Zhang Chao saw that everyone was staring at him, and then his voice became smaller and quieter, and finally he didn't move at all.

"Well, that's a good point." Chen Zheng suddenly remembered the previous mural.

The legacy of experience left behind by that destroyed civilization is very valuable for reference.

"For the record, the threats I can think of right now are 'dragons', spore infestations, and those little bugs. So we need stronger drones, better medical examinations, better protective measures, better shelters, and more powerful flamethrowers. ”

"The robot continues to move forward, and if it can follow the clues to find the black skin, nothing else needs to be mentioned."
