It's reasonable for me to have a two-way foil for a second-level civilization, right?

The cap is broad and brightly colored.

Like the accretion disk of a black hole.

Coupled with the towering trees that are often hundreds of meters high, a fantasy picture is clearly presented in front of everyone.

Under Zero's control, the hatch on the side of a detector slowly opened.

Several small robots quickly stepped out of the hatch, and walked towards the blade with solid steps.

Sample, contain...

The robot that finished sampling the leaves quickly got up and put the samples back into the detector.

Chapter 593 Abnormal Vibration

"Quiet."

"It's too quiet."

Mao Zhengzhi stared at the fantasy scene in the holographic projection like a scroll, and squeezed out a few words from between his teeth.

Lu Yongchang also nodded solemnly.

As Academician Mao Zhengzhi said, this forest is so quiet!

Except for the sound of the wind blowing the broad blades, there is hardly any other sound!

In many cases, being quiet is the biggest anomaly!

"Are there no animals on this planet..."

Lu Yongchang muttered to himself in doubt.

When everyone was confused, Zero still carried out the sampling task in an orderly manner.

After the leaf sampling work is completed, it is trunk sampling, soil sampling, and associated fungus sampling.

Soil sampling is simple.

Under Zero's control, the robot did the job quickly.

The most difficult thing is the sampling of trees.

The reason... is naturally that the hardness of these tree trunks far exceeds the imagination of Lu Yongchang and others!

But also understandable.

From the appearance point of view, these 12000-meter-level trees belong to the same species as the [-]-meter-high giant tree.

These tree trunks can support such a huge object under the gravity of 1.5g, and the strength can be imagined.

But all of this became false after the robot was replaced with a drill bit made of the same material as the starship shell.

Under the impact of the star gold-carbyne composite drill bit, a cylindrical sample that runs through the cross section of the tree was taken out.

"Professor, the detector detected some abnormal vibrations on the ground."

At the same time as the electronic synthesizer sounded, all the robots put down the scientific research equipment in their hands, revealing the small laser guns installed on the mechanical arms.

Driven by the fusion battery, the muzzle of the gun shone with lavender light, and the surrounding temperature also rose rapidly, causing a slight distortion in the calm air.

The vibrations are gone.

But the robots still maintained their original movements, looking around vigilantly.

10 minute later.

"No unknown creatures were found."

"Comprehensive judgment, the source of the vibration is a slight earthquake."

"The alert has been lifted, and the original sampling task will continue."

The lavender light gradually dissipated, and the small laser gun was retracted into the mechanical arm.

……

After half an hour.

"The sampling work at each landing site has been completed."

"Probe ready for return operation."

Zero's report surrounds the lab.

It was supposed to be a staged progress, but there was no smile on Lu Yongchang's face.

He looked at the holographic image in front of him very solemnly, with doubts in his eyes: "What do you think of the shock just now?"

Mao Zhengzhi next to him stared at the data in the projection, and heaved a long sigh.

"Almost simultaneously, all surface detectors detected this slight tremor."

"Like an earthquake, but not at the frequency of seismic waves."

"It's very strange." Mao Zhengzhi turned his head, stared seriously at Lu Yongchang's eyes, and repeated again, "It's really strange."

Lu Yongchang was silent for a moment, then said softly, "You don't think this is an earthquake, either?"

Mao Zhengzhi nodded silently: "What a coincidence."

"Almost all robots were performing tree trunk sampling at the time."

Lu Yongchang stared at the robots entering the detector one by one in the screen, thinking carefully about the next measures to be taken.

In his heart, the possibility that this planet is the work of an advanced civilization has been raised to the first place!

But after all, there is no definite evidence.

Today's human civilization needs all the resources that can promote development!

Never give up these valuable resources because of some assumptions with insufficient evidence!

"All the probes loaded with samples have returned."

After pondering for a long time, Lu Yongchang finally spoke again: "The rest of the probes have entered the low-earth orbit of the lost star to conduct real-time observations on the surface of the lost star."

"In addition, execute the second batch of wake-up plans."

"Next time you land on an exploration mission, send some experienced planetary explorers up."

"receive."

At the same time as the electronic synthesizer sounded, Mao Zhengzhi's voice also sounded.

"Professor, is this too risky?"

"At present, there are still a lot of mysteries in the Lost Star that have not yet been solved, so I rashly dispatched planetary explorers..."

Before Lu Yongchang could speak, Fang Xu on the other side interrupted Mao Zhengzhi's voice.

"It is precisely because of this that we need to send planetary explorers."

"You have also seen the surface environment of the Lost Star."

"Complicated forest landforms, extremely soft soil..."

"In such an environment, zero-sum robots can only play a role in assisting exploration."

"If you want to really uncover the veil of the Lost Star, it is essential to send explorers to conduct landing exploration."

……

The probe left.

Only a part of the probes remained in the low-earth orbit of the lost star, quietly staring at the forest below.

But under the cover of layers of tree canopy, the detection effect is not very good.

The soft soil trembled slightly.

A section of thick tree roots slowly drilled out of the ground and stretched out to the area where the probe landed.

It crouched as far as possible on the scorched black surface, as if there was honey on it.

Time passed slowly.

With the rotation of the Lost Star, night came.

The bright accretion disk covering the entire sky slowly disappeared at the end of the horizon.

Since the last "great change of heaven and earth", the night has become colder and colder.

The tree roots crouching on the scorched ground twitched slightly, as if sensing the cold surrounding, they retracted into the soft soil again.

At night, this quiet forest finally becomes lively.

Huge arthropods crawled out of the dense canopy, pulled their huge number of gastropods, and crawled towards the ground along the thick trunk.

They crawled very fast, and they climbed down the [-]-meter-high tree trunk in a few seconds.

After reaching the ground, they quickly climbed to the bottom of the tree trunk without the slightest hesitation.

Over there, there is the food they desperately need.

These foods, which are shaped like the big disc in the sky, can only be safely eaten at night.

After a few of the arthropods were full, they moved their legs and twisted their bodies, and came to a slightly raised mound.

The soil of this mound is extraordinarily soft, as if it has just been turned by something.

Head to head, they exchange information with each other with their antennae.

"It's dead."

"Yes, it's dead."

"it's a pity."

"How many times have I told it that I can't go down to look for food during the day, that's the devil's bait, and it just won't listen!"

"Ah... what a pity..."

After the communication, the arthropods turned around and crawled away.

While the night is still dark, they need to find food as much as possible.

As for the regret just now?

After taking ten steps, they were completely forgotten by them.

Chapter 594 Unidentified Creatures

The night is dark.

A huge arthropod is rapidly swinging its hundreds of gastropods, twisting its body covered by a hard exoskeleton, and nimbly walking through the lush forest.

Occasionally, it would slow down its pace a little, and lower its head to nibble two bites of food at the root of the tree trunk beside it.

Even though the food in this area is very rich, it still has no intention of staying.

suddenly.

For the first time, it stopped its hurried small steps, raised its head and looked forward.

A light breeze blows, blowing a warm and somewhat damp breath.

It sticks its abdomen on the soft ground and feels it carefully.

Fine vibrations came from the front, as if foreshadowing something.

After confirming the specific direction, it swung its legs again and walked forward quickly.

After a few seconds, the vision suddenly widened!

The lush forests come to an abrupt end here!

Ahead, there is an endless ocean!

As it moved forward, its body spontaneously underwent some changes.

The color of its body surface changed, becoming very similar to the color of the beach.

For it, this is like instinct, and it hardly consumes any energy.

It ran to the beach quickly, lowered its head and took a few sips of the slightly warm fresh sea water.

Then, it raised its head and looked around.
