Chapter 726

Zhang Yuan sighed and carefully observed the pictures on the screen. Whether it's humanitarian or investigating the cause of the accident, finding survivors is really a good plan.

However, the probability of surviving the wreckage of the spacecraft is very small, and the probability of underground base is higher.

The crisis has not been completely ruled out. After some basic consensus was reached, the meeting was soon dissolved. Both sides began to restrain the people, reduce surface activities, and began to retreat strategically.

The War Star "Shanhai" of the new human civilization and the planet "Kalina" of the hemispheric civilization turn on the curvature engine and retreat to a place 200 astronomical units away from the ruins of the tosian civilization. This distance is safe enough.

Only the Kyushu Planetary Fortress remained in its original position as the central headquarters of the front exploration force.

Kyushu, as a military planet, has the most complete means of defense, which can withstand all kinds of twists and turns. In other words, if there is a real insurmountable danger, it is not impossible to abandon the planet and let it stand behind!

This safety measure took three days in total.

After that, the front-line unmanned investigation force has also approached the destination, and began to feed back the pictures. The whole investigation force is divided into two parts. One team approaches the ruins of those spaceships, and the other team begins to investigate the main base of the colonized planet of TOS civilization

"What happened?"

Zhang Yuan was not in a good mood and was not very steady in his sleep and rest.

TOS civilization is also an old friend of mankind. People have learned a lot from those giant giant giant salamanders. Some good electromagnetic technologies are provided by these giant salamanders. But judging from their current performance, they may have suffered some misfortune

If this kind of misfortune comes to human beings, can human beings resist it?

This kind of worry makes him a little restless, eager to find out the truth immediately.

Several colleagues next door are discussing in the conference room: "well, I don't know if any survivors have escaped. They're not going to die. "

They deeply lamented that the fourth level civilization was in trouble. It was really fragile.

"It should be. I found that the wreckage of these spaceships were all facing the same direction. It should be that they were attacked when they were fleeing. But in theory, there are spaceships that can leave smoothly, and their total population is over 100 million, which is not only what these spaceships can carry. "

"That's true."

"Do you think it's a five level civilization It's an internal riot in the Toth civilization? "

Zhang Yuan shook his head: "the possibility is not high. The social structure of these giant salamanders is quite stable and has not changed for so many years. In the 400 years since we left, drastic changes have taken place all of a sudden? The probability is very low... "

"Of course, we can't rule out that the TOS civilization played off some kind of black technology, and there was an incident similar to the sinking of our bright galaxy, and there was an internal riot."

"Black technology?"

During the conversation, the first group of uninhabited investigation troops have fed back the pictures they have captured.

From the satellite photos, we can see that it used to be a highly prosperous colonial planet. There are as many as 16 space ports alone, and there are still some large spaceships that have never left.

These spaceships are almost intact. They are industrial grade nuclear fuel transport spaceships, suitable for short-range navigation.

Maybe the whole civilization will be paralyzed before it can be started

Seeing this, Zhang Yuan locked his brow and thought hard.

He felt vaguely that since there were still intact spaceships in the port, the probability of finding survivors inside the base was not very high

It seems that a ground war broke out in the surface base, many infrastructures were destroyed, and the concrete ground that had been ground flat appeared pits. The glazed soil is the mark of the nuclear weapon attack, and the lumps of all kinds of metals that re coagulate after cooling are piled on the ground.

"Look

A staff member in front of the screen seemed to have found something and said in a loud voice, "is this the crater drilled by the heavy armor piercing bullet?"

Zhang Yuan turned his head and looked along the screen.

From the inside of this crater, we can see the condition inside the underground base.

Due to the complete power failure of the base, it is dark inside, and only the remains of some robots can be seen under the searchlight.

Deeper underground, there are still lights flashing.

During the conversation, more than 100 alliance exploration robots landed on the ground.

"Do you want to go straight in and investigate?"

"It's too far away, so don't give orders."

In order to ensure safety, the distance between the command center of Kyushu and the front line, full 10 hours of signal delay, so these robots are all automatic exploration.

If something happens, human beings can also send a certain degree of mandatory command.Only 10 hours later, the robot will be able to receive the information and respond accordingly. In this case, the robot is not allowed to come by itself.

Mechanical wreckage, craters, and some scattered corpses, the cruelty of the war, for a while and a half, let everyone breathless.

"TOS civilization was in a hurry to leave." Zhang Yuan's brow tightly wrinkled, "even the remains have no time to clean up, they ran away in a hurry. This shows that they think they have encountered an irresistible disaster and can't leave one second later. "

After a while, the other side of the spacecraft remains investigation forces, also came to the shooting results.

From the ruins of the destroyed flagship, it is full of various bullet marks. That is to say, there is nothing special about the conventional weapons, electromagnetic guns, lasers and some missiles of the third and fourth level civilizations.

But what's even more strange is that after investigation, it was found that some shells were actually launched from the inside, just like civil strife and the whole spacecraft exploded.

"How could that be?"

Zhang Yuan saw a mass of bloody and charred objects, sighed again, this should be the body of a big dog "momoro", but now the big dog has died, frozen in a vacuum environment.

It's really strange. According to Zhang Yuan's understanding, those giant salamanders are really Buddha like creatures. When they first developed the war star together, the endurance of this race was much stronger than that of human beings. How could they suddenly become like this?

Sitting beside Zhang Yuan, Li Zhendong said in a low voice: "external factors, probably caused by external factors!"

"We have to be careful. Some external cause suddenly led to internal chaos. In the process of evacuation, even the escape ship was in chaos!"

Zhang Yuan frowned and said, "but have you found that all the robot remains are from the tosian civilization. We didn't find the remains of alien civilization

"Maybe the battlefield has been cleaned up. It could be something else. "

It's already nine o'clock in the evening, and all the insiders are tirelessly discussing and guessing.

"If it's really the work of the five level civilization, what are its means of attack? Why did it attack the Toth civilization, just to seize the base? "
