The village-level spacecraft is a dual-purpose type of near-earth space and space, and within the dense atmosphere, the village-level spacecraft can also fly freely.

As the altitude decreased, the thermal imaging detector gradually captured the surface of the planet. Xiao Yu saw that on this planet, there was an endless desert, no water, no liquid substances, and no traces of living things.

At the same time, Xiao Yu also detected strong nuclear radiation. Xiao Yu knew that it was left over from the hydrogen bomb that he exploded on the other planet.

The five village-level spacecraft did not land directly, but were guided by more than 80 satellites in the sky to search for the planet.

The results of the search surprised Xiao Yu. Because although this planet is large, the traces of intelligent life activities occupy only a very small part. Xiao Yu only found a complex of buildings similar to a human city in one place, dozens of giant buildings with a height of 10,000 meters above the planet's equator, and only a few places similar to mining bases were found in the rest.

Xiao Yu speculated that the dozens of giant buildings that were 10,000 meters high should be the super giant fusion engine that propelled the planet to move.

On the entire planet, only one biological gathering city was found, and this phenomenon made Xiao Yu puzzled.

"Do they live underground? No, it's unlikely, why would they build cities on the ground if they live underground? Anyway, let's go check it out first. ”

Xiao Yu thought about it, commanded a village-level spaceship to land on the edge of the city, and two hundred robots formed a line, lined up in a neat line, and began to march towards the city.

These robots have been specially modified by Xiao Yu, and their materials can resist the corrosion of high concentrations of sulfur in the planet's atmosphere, and at the same time, these robots are equipped with Xiao Yu's newly developed Gauss pistol, under Xiao Yu's control, these robots have amazing melee Liliang.

The Gauss pistol is not a pistol that fires bullets through gunpowder, but accelerates the jishu to shoot bullets through an electromagnetic coil, and its bullet initial velocity is very high, and correspondingly, the lethality is naturally very strong.

The electromagnetic coil accelerates jishu, which is used in space warfare, is the high-velocity machine gun equipped on Xiao Yu's spacecraft, and after miniaturization, it is a Gauss pistol.

The style of the city is very strange, unlike any architectural style known to Xiao Yu, most of its buildings are low, except for buildings that are obviously used for special purposes such as scientific research and military affairs, the rest of the buildings are no more than five meters high. Xiao Yu speculated that this may be due to better access to geothermal heat.

The low-rise building brought convenience to Xiao Yu. Because there is less occlusion from the building, Xiao Yu can more accurately scan the ground for active heat sources to determine whether they still have a surviving liliang.

In the darkness of the earth, two hundred robots equipped with night vision devices slowly dispersed and explored the city.

Xiao Yu wanted to know, in this month, what happened on this planet, in the battle between the wood spirit and these intelligent creatures, was the wood spirit victorious and wiped out the other party, or did the other party destroy the wood spirit?

If it was the wood spirit that wiped out the other party, where did the surviving wood spirit go? If it was the other party who eliminated the wood spirit, would they still resist Liliang and ambush here waiting for Xiao Yu?

This is an alien planet, this is an alien city, there is no light source here, the air is full of high concentrations of sulfur, and the environment here is like hell for humans.

Fortunately, these robots do not feel fear, otherwise, the psychological pressure that such an environment can bring, even specially trained special forces may not be able to bear.

A robot broke away from the large group and walked towards a ten-meter-tall building. Among the complexes of buildings generally less than five meters, this ten-meter building stands out unusually well. Xiao Yu guessed that there must be something important stored in it.

Ahead, a little vibration suddenly spread through the air, which was picked up by the detector equipped on the robot.

Where there is air, vibration means sound.

This signal was quickly launched into the temporary base by the transmitter on the robot's body, and then launched into the Sun through the satellites in the sky, and immediately, this signal aroused Xiao Yu's vigilance.

In the thermal imaging detector, a moving object appeared. It was a strange creature less than thirty centimeters tall, two meters long, and six legs.

This creature is very similar to the lizards on the earth, except that this creature has a large head and does not have such a long mouth.

The creature kept emitting strange unintelligible syllables from its mouth and kept backing away from the building, seemingly terrified of the robot. Seeing its movements, Xiao Yu's heart moved.

Ordinary creatures with low intelligence can only make a few kinds of sounds, and they can produce so many syllables with different tones, which means that this creature should have intelligence.

Xiao Yu immediately manipulated the robot to aim the Gauss pistol at it, and first shot it in front of it. Immediately, the high-velocity Gaussian bullets cracked the ground inch by inch, and the creature screamed, stopped moving, as if it had fainted.

Xiao Yu felt very funny, so he manipulated the robot to step forward, picked it up, and walked outside, after meeting with the robot army, five robots took out a high-strength rope, tied it into a knot, and put it in a village-level spaceship waiting outside, and then the village-level spacecraft took off and entered the inside of the Sun.

Here, Xiao Yu has long prepared various instruments for haode. Xiao Yu plans to do a comprehensive examination of it to understand the various physical signs and data of this intelligent creature.

"Although you have caused me great losses, but you have failed, as the victor, I have no interest in torture and killing, you can go and see your god happily."

Xiao Yu thought about it, and manipulated the robot to cut off its head without hesitation, so that it died in a coma without the slightest pain.

Subsequently, a comprehensive inspection began, and Xiao Yu studied the data one by one.

"Thermostatic animals, the body temperature is maintained at about 27 degrees, and the brain capacity is 3,000 milliliters, which is not much different from humans...... Hermaphroditism? Can you reproduce on your own? That means they don't have aiqing, they don't have a family, well, this biological society must be cold. ”

"Like humans, it relies on fluids to transport nutrients in its body, and it has a huge digestive organ, well, and its immune organs are also quite strong." Xiao Yu studied little by little.

Slowly, a strange phenomenon caught Xiao Yu's attention.

"They...... Originally, it appeared to walk upright, which is evident from the fact that the forelimbs are significantly weaker than the hind limbs. It seems that they also went through the evolutionary process of crawling to upright walking at first, and then, for some reason, they went back to crawling walking. The most likely is to obtain more geothermal energy from the planet. ”

"Huh? This is...... Already degenerated optical sensing organs? These are their eyes? Xiao Yu saw that their eyes had degenerated, and a heat sensing organ had taken the place of the eyes.

Gradually, Xiao Yu analyzed and came to a conclusion.

"They should not be the original species on this planet, it seems that they migrated from a completely different environment, and then, in order to adapt to the environment of this planet, they not only changed from walking upright to crawling, but also from optical perception to thermal perception."

"Every civilization has its own magnificent story." Xiao Yu sighed and continued to study.

To capture this creature, Xiao Yu also has another purpose, that is, to study its physiological structure more haode in order to develop more lethal weapons.

Since there are creatures, it means that in the process of the wood spirit fighting them, it is the wood spirit that has been eliminated, and it also means that they must still survive. Xiao Yu can't allow them to continue to live, but Xiao Yu can't directly attack the city with hydrogen bombs or the like, because in that case, the electronic equipment in the city will also be destroyed, and Xiao Yu won't be able to get the information he wants.

The killing of the wood spirits was carried out instantly, and it was impossible for them to have time to prepare and destroy all the information, so Xiao Yu had no interest in arresting them for interrogation, and if he wanted to know anything, he could just search for information in the electronic device.

After a thorough study of the lizardman's body structure, an idea appeared in Xiao Yu's mind.

"In this case, infrasonic weapons are more suitable, only killing living things, and have no effect on buildings, electronic equipment, etc."

"Infrasound at a frequency of nine hertz is the most suitable." Xiao Yu came to a conclusion and immediately began to develop the corresponding infrasonic weapon. In interstellar space, infrasonic weapons cannot be used, but on the surface of a planet with a thick atmosphere, infrasonic weapons are very useful.

The killing principle of infrasonic weapons is to resonate with the organs in the organism through low-frequency mechanical longitudinal waves, causing their organs to deform, displace or even rupture, so as to achieve the purpose of killing.

During this period of time, Xiao Yu carried out a large-scale landing activity while carrying out busy weapons research work. The number of village-level spacecraft that have reached the surface of the planet has reached more than fifty, and more than 10,000 robots have been released into the city to carry out various exploration activities.

In the city, the robot formation was resisted by the lizard people from time to time, and Xiao Yu showed no mercy and killed them one by one. But this kind of rebellion also made Xiao Yu annoyed.

Time passed bit by bit in this situation, and finally, the giant infrasonic weapon developed by Xiao Yu could be put into actual combat.

Xiao Yu made a total of five of these giant infrasonic weapons, which were mounted on five village-level spaceships. These five village-level spaceships were suspended above the city by Xiao Yu, and the entire city was within the killing range of these giant infrasonic weapons.
