Amon was studying weapons, but Xiao Jiang was paying attention to the front. At this moment, the detection spacecraft approached the border of the Tiandu Empire at fifty times the speed of light. It was about one light year after reaching the border from the wormhole exit area. In less than a day, the detection spacecraft had escaped from the super-light speed. At nearly ten million kilometers ahead of the spacecraft, a light blue planet was slowly moving around the stars in the distance along orbit.

"SAS planet, the life planet on the edge of the Tiandu Empire, has a diameter of 18,000 kilometers... This planet is far away from the Tiandu Empire because of its lack of mineral resources. It was once the prison planet of the Tiandu Empire."

Xiaoxing explained the planet in front of him. Xiao Jiang opened the detection system and frowned while releasing the detection satellite:

"I feel a little weird. According to Xia Mi, this prison planet is all imprisoned for serious prisoners. Shouldn't this outer space have defensive facilities? It's a bit strange that I didn't see the defense facilities during the scan."

Amon looked at the data ahead and scanned, and scratched his head and said:

"It's true. If it were a prison planet, there must be at least a space base outside. However, the entire outer space of the planet is not even an asteroid, and the nearest planet is hundreds of millions of kilometers away. Wouldn't it be easy if someone robbed the prison?"

Xiao Jiang was also puzzled for this situation. As the detection satellite approached the SAS planet, the detection images became clearer and clearer. This planet has a scattered water source area but does not have a large-scale connected ocean. The mountains everywhere are rings. The analysis concluded that before the planet produced life and atmosphere, it had been hit by countless asteroids to form large-scale craters, and those water source areas were lakes or small oceans inside the crater.

But after a while, the satellite had reached the planetary synchronous orbit. As the scanned high-definition images gradually formed, Xiao Jiang's eyes were fixed and he looked at a map. This was a small plain outside a large crater. There was a house area several kilometers wide built on the plain. Looking at the tall walls and signs of various posts, this should be a prison, but there was no one inside or outside the prison in the image.

When the complete image of the planet scanned by satellites came out, Xiao Jiang had found more than 30 prisons of all sizes and more than a dozen small cities, but like the first prison, there were no traces of biological inside and outside the buildings, and even no animal hot traces appeared on the entire planet.

As the spacecraft slowly approached the SAS planet, Xiao Jiang kept analyzing the data and said:

"What's wrong. There are no detectable traces of animals on this planet. What's going on?"

Amon muttered:

"There are no traces of animals, but the vegetation above is so rich. The temperature and air quality of the planet are very suitable for the existence of living organisms. How can there be no traces of animals?"

Xiao Xing on Xiao Jiang's shoulder turned his head around and said:

"Virus, war, and cosmic rays may cause biological extinction, but according to the scanning data, there are no traces of war on the planet nor any residual radiation waves, so these two situations can be ruled out, and the only thing left is viruses or unknown causes."

Amon said in surprise:

"Virus? What kind of virus will exterminate all animals but retain sufficient vegetation?"

Xiaoxing said without any hesitation:

"According to what I know, the number of viruses has reached more than 300 million. The properties of various viruses are different. However, I have no data on viruses that can kill all living organisms at the same time, because viruses need to pass on their own genes. Killing all hosts is equivalent to eliminating themselves. That is not a normal virus but a suicide virus."

Xiao Jiang frowned and said:

"If you want to know what's going on, you have to investigate it, launching atmosphere detectors and micro-robots into various areas for investigation."

Amon asked:

"Aren't we going to enter the Tiandu Empire to contact the other party's forces? How can we investigate the situation here first?"

Xiao Jiang opened the signal analysis system of the spacecraft and made a schematic diagram. Xiaoxing directly connected to the data on the system and said:

"According to the analysis of various signals received by the signal receiving device, there is an artificial signal interference area in the area 1.5 billion kilometers away. All communication signals have become garbled codes. If you try to crack some signals, you can only get some messages, that is, the Tiandu Empire is being attacked by large-scale cosmic locusts, and the rest are unknown."

"What? Cosmic locusts? What kind of creature is this?" Amon asked in a daze.

Xiaoxing said:

"The universe locust is translated based on cracking signals. The creature has space flight capabilities, the maximum speed can reach sub-light speed, and is not afraid of low temperatures and high temperatures. Its own shell can withstand strong impacts. Wherever it passes, all living things will be swallowed by them. If the calculation is correct, the life bodies on the SAS planet will be eaten up by the universe locusts."

"Eat it? Why are the vegetation on this planet still there?" Amon asked.

Xiaoxing said:

"Because cosmic locusts do not eat vegetarian food, they are only interested in organic living organisms and organisms with blood cells. Perhaps they can ignore this cosmic locust, but humans and animals are their vegetables."

Amen glared at his eyes and was about to speak, but suddenly he saw the ground robot on the projection screen next to him starting to scan the pictures everywhere and said in surprise:

"Tao, don't eat vegetarian food yet. Hey, why are there no biological remains in the picture sent back by the ground robots, and there are not even the so-called cosmic locust corpses? Do they even eat bones?"

Xiao Jiang touched his chin and said thoughtfully:

"It seems that this is true. Cosmic locusts can actually reach sub-light speed in space. What does this mean? It means that this organism has a powerful body and a special way of flying. I believe that this cosmic locust will not fly by flapping its wings. Their physical fitness determines their specific properties. I wouldn't be surprised to say that they can eat metals and absorb energy."

"Didi."

Just as Xiao Jiang finished speaking, a dripping sound rang out, and an image was magnified in front of Xiao Jiang. This was a special confinement room in a prison. The metal door of the confinement room was closed and the window was tightly closed. However, it had been opened under the cutting of the robot. In the confinement room, a white bone was sitting against an iron bed. On the ground in front of him, a strange corpse of insects as thick as an arm made Xiao Jiang's eyes lit up.

Xiao Jiang rubbed his hands and said:

"Let the robot come back with the corpse of the insects and the landing craft. This insect is probably a cosmic locust. It looks so evil and terrifying."
