In the dark cave, only the creaking sound of tracks echoed.

The explorer and the cleaner move forward one after another. The instruments on the explorer constantly send information about passing caves back, and after processing by the server, they form a 3D map in real time.

While operating the robot, George not only sighed that although the food here can be described as hell, these devices made him feel a little overwhelmed.

In the tent, except for the operators staring at the screen nervously, Chen Zheng and the man in glasses also focused on the two robots that were constantly moving forward.

The long tunnel continued to extend forward. After walking almost two kilometers, two robots then came out from under the surface.

When ice and snow appeared on the screen, the operators began to calculate quickly... Through extremely high-precision map modeling, the operators quickly calculated the location of the exit.

"The exit is southeast, where there are woods," an operator reported.

"Collection of 20 drones over."

After saying that, Chen Zheng lifted the tent and rushed towards the woods in the southeast.

The exit location had been sent to Chen Zheng's personal terminal. I searched according to the location of the map and soon found the not-hidden cave entrance in the forest.

I looked around and found no very obvious footprints, but Chen Zheng soon discovered some passive marks on the nearby branches.

Based on these traces, it is easy to infer the black skin's movement pattern - relying on his tentacles to wrap around the branches, swinging like a monkey in the middle of the woods.

After discovering it, Chen Zheng quickly followed the trace and left.

At this time, the two robots were still leaving, and Chen Zheng's figure naturally flashed and disappeared on the screen.

"...This is flickering... It's really..." A newly promoted earth operator was shocked by this scene and didn't know what to say.

"Well, it's amazing, isn't it?" George looked like an old senior. "When the adults took me to fly from the bottom of the valley to the top of the cliff, the feeling of personal experience was more than ten times more shocking than it seemed... I'll tell you..."

“…”

In the tent, some slightly exaggerated gossip that didn't know the truth or the false was constantly coming from George's mouth... The glasses standing behind them did not restrict them. They walked to the corner and sat down, listened to these earthlings chatting, closed their eyes and started to sleep.

...

Following the traces on the trees all the way, Chen Zheng passed through the entire forest, and the traces disappeared outside the Shunlin.

In front of me, there is another vast plain. Unless black skin has wings, it will inevitably leave a trace on the snow.

But the snow field ahead was pure and flawless, as if the black skin had really flew into the sky and disappeared into the blue sky from now on...

But is this possible?

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

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

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

"……really."

Chen Zheng smiled.

Although the traces on the tree are not heavy, there are some subtle differences between the two traces. If you don’t look carefully, you may be deceived by him.

The method used by Black Pi is very simple. After walking to the end of the woods, then carefully return the same way. Each mark controls the overlap with the last mark.

Not only will humans use such skills, but some animals that have lived long enough will also use this trick to confuse predators.

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

When the secondary traces disappear, the black skin naturally hides and hides.

Chen Zheng searched around and found a newly dug cave on a leeward hillside.

It's hidden here?

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

Although the cave is pitch black, the space inside should not be very large. At least you can't feel the flow of air flow or hear the echo inside when standing at the entrance of the cave.

If you are careful, Chen Zheng should be here at this time and then notify the man with glasses and they will send the two robots over.

However, it took at least a whole day to do that - although Hei Pi's movement speed was much slower than Chen Zheng, he also walked a full two days to get here.

In fact, snowmobile is not suitable for moving forward in the woodland. When you encounter situations where you cannot take a detour, you need to open a passage by yourself. Even if you drive straight, it will be dark here with the speed of the snowmobile.

So Chen Zheng decided to take this risk, and Chi Ze changed. What if Hei Pi escaped again? Although he didn't know how big the entire wilderness star was, in terms of the entire planet, once spring comes, without the trouble of snow, Chen Zheng really has no choice if Hei Pi wants to hide.

With a mask on it, he summoned the lightsaber and Chen Zheng carefully drilled into the narrow hole...

Sure enough, the cave is not deep, about ten meters deep. However, there is a nearly half-fold curve every two or three meters - this should be a measure used by black skin to keep it warm.

Whenever he passed by the corner, Chen Zheng had to take a twelve-point focus and always calculate the position of his flashing. If something happened, he would leave the cave immediately.

However, until the last corner, the expected risks did not appear...

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

To be precise, it was a corpse with empty shells and loose skin, as if it had been absorbed with essence.

Although his face could not be seen clearly, it can be seen from his skin that this person was Hei Pi who was chased by Chen Zheng. Unexpectedly, he escaped from the canyon and died here inexplicably.

"..." Chen Zheng stood in front of his body and was silent for a while. He picked up a branch and picked up the human skin... and then he saw a pile of messy shells sliding down from his body.

Chen Zheng was wearing a protective suit and a mask on his face. He was not afraid of any spores, so he checked it very carefully.

There was only one fatal injury on Hei Pi's body - an oval small hole on the top of his head, which was about the size of a dime coin.

Strangely, the black-skinned bones seemed to be soaked in a strong acid solution, and the whole body was crispy, and it would fall apart with a slight movement.

"Click..."

Chen Zheng stepped on something... When he looked down, he found that it was a thin piece with a little gray color.
