In the dark cavern, only the creaking of the tracks echoed.

The explorers and cleaners are moving forward one after the other, and the instruments on the explorer's body continue to send back the information of the caves they pass by, and the 3D map is formed in real time after being processed by the server.

While operating the robot, George not only sighed a little, although the food here can be described as hell, but these devices make him feel a little in love.

In the tent, in addition to the operators staring nervously at the screen, Chen Zheng and the man with glasses also focused their attention on the two robots that were constantly advancing.

The long tunnel continued to stretch forward, and after walking for almost a full two kilometers, the two robots emerged from beneath the surface.

When the ice and snow appear on the screen, the operators start to calculate quickly...... Using extremely accurate map modeling, the operators quickly deduced the location of the exits.

"The exit is in the southeast, and there's a grove there." An operator reported.

"Mobilize 20 drones to go over."

After speaking, Chen Zheng opened the tent and rushed to the woods in the southeast.

The location of the exit had been sent to Chen Zheng's personal terminal, and he searched for it according to the location of the map, and soon found the cave in the forest, which was not hidden.

Looking around, there were no very obvious footprints, but Chen Zheng soon noticed that there were some traces of movement on the nearby branches.

From these marks, it is easy to deduce Blackskin's pattern of movement, relying on his tentacles to wrap around the branches, swinging like an ape in the middle of the woods.

After discovering it, Chen Zheng quickly chased the traces and left.

At this time, the two robots had not left, and Chen Zheng's figure naturally disappeared on the screen.

“…… That's flickering...... It's really ......," a new Earth operator was shocked by the scene and didn't know what to say.

"Well, it's amazing, isn't it?" George put on an old-timer look, "When the adults took me from the bottom of the valley to the top of the cliff at once, the feeling of my own life was more than ten times more shocking than it looked...... I'll tell you......"

“……”

In the tent, some slightly exaggerated gossip that I don't know whether it's true or false keeps coming out of George's mouth...... The glasses standing behind them did not restrain them, and they walked to the corner and sat down, listened to the conversation of these earthlings, closed their eyes and pretended to sleep.

……

Tracing the traces on the trees all the way, Chen Zheng walked through the entire forest, and the traces disappeared outside the forest.

Ahead, there is a vast plain, and unless the black skin has wings, it will inevitably leave a trace on the snow.

But the snowfield in front of him was pure and flawless, as if the black skin really flew into the sky and disappeared into the blue sky......

But is this possible?

Although considering the weirdness of those bugs, the option for the black skin to grow wings will not be zero, but ......

…… Chen Zheng stood at the place where the trace disappeared silently, and suddenly turned around and walked back.

On the way back, Chen Zheng observed every trace very carefully, until one place Chen Zheng suddenly stopped, turned around and returned to the branch where the previous trace appeared.

“…… Really. ”

Chen Zheng smiled.

Although the marks on the tree are not heavy, there are some subtle differences between the two marks. If you don't look closely, you might really be deceived by him.

Blackskin's method is very simple, walk to the end of the woods, and then carefully return the same way, each mark is controlled to coincide with the previous one.

This trick is not only used by humans, but also by some animals that have lived long enough to confuse predators.

However, the traces left by the black skin are not footprints after all, and no matter how careful the traces left by the tentacles are, they will inevitably leave some clues the second time.

When the secondary traces disappear, it is naturally the hiding place of the black skin.

Chen Zheng searched around, and sure enough, he found a newly excavated cave on a leeward hillside.

It's hiding right here?

Chen Zheng turned on the flashlight and shone it into the cave.

Although it was dark in the cave, the space inside should not be very large, at least standing at the entrance of the cave, you could not feel the flow of air, and you could not hear the echo inside.

If it was prudent, Chen Zheng should have stayed here at this time, and then informed the man with glasses that they would send the two robots over.

However, it would have taken at least a full day to do so—although Heipi's movement speed was much slower than Chen's, it had taken him two full days to get here.

In fact, snowmobiles are not suitable for driving in woodland, and if you can't make a detour, you have to open a passage by yourself. Even if you drive up a straight road, it's dark here at the speed of a snowmobile.

So Chen Zheng still decided to take this risk, and later it will change, what if Heipi escapes again? Although I don't know how big the entire desolate star is, in terms of the entire planet, once it is spring, there is no trouble with the snow, and Chen Zheng really has nothing to do if the black skin wants to hide.

Wearing a mask and summoning a lightsaber, Chen Zheng cautiously slipped through the narrow hole......

Sure enough, the cave is not deep, about a dozen meters deep. It's just that every two or three meters there is a bend that almost folds in half - this is supposed to be a measure used by the black leather to keep warm.

Whenever he passed around the corner, Chen Zheng had to pay twelve points of attention, and always calculated the position of his flash, and once something happened, he would leave the cave immediately.

However, until the last corner, the expected risk never materialized......

Then, Chen Zheng saw something that made him creepy - a human skin.

To be precise, it was a corpse with an empty carapace, loose skin, and as if it had been sucked out of essence.

Although his face was no longer visible, it could also be known from his skin color that this person was the black skin who was chased and killed by Chen Zheng. Unexpectedly, he escaped from the canyon, but died here for no apparent reason.

"......" Chen Zheng stood in front of his corpse and was silent for a while, picking up a branch and picking at the human skin...... Then he saw a mess of carapace sliding down his corpse.

Chen Zheng was wearing a protective suit and a mask on his face, but he was not afraid of any spores or anything like that, so he checked very carefully.

There was only one fatal wound on the black skin's body - a small oval hole in the top of his head, about the size of a dime.

Strangely, the black-skinned bones seemed to have been soaked in a strong acid solution, and the whole thing was crispy, and the slightest movement would drop off the slag.

"Click......"

Chen Zheng stepped on something...... When I looked down, I saw that it was a thin sheet of grayish color.

"It's ...... Eggshell!? ”
