After realizing that he might have encountered a more advanced alien civilization, Xiao Yu immediately turned all the 110,000 spaceships, as well as more than 1.5 million steel armor robots, to the radio silent mode, turning off all visible light and engines, so as to prevent the lights or the tail flame of the engines from exposing the location of his fleet. At the same time, Xiao Yu turned on various observation equipment to the maximum power.

In the boundless dark universe, Xiao Yu stalked silently.

Jin Ye had already dressed up in a cosmic battle armor and was ready for battle.

The armor has a height of nearly two feet, a pitch-black metal shell, and a cold appearance, like a killing machine born specifically for killing.

If you count the skills you have cultivated for a year of meditation as one year's skills, in the past nearly three thousand years, with the help of various elixirs and the perception of the exercises again and again, Jin Ye has 10,000 years of skills, and his combat power is close to that of a county-level spaceship.

Not only that, but Jin Ye also specially created a battle armor for himself according to the environment in the universe, the Douzhan No. 1 Armor. Due to the limited space on the armor, Jin Ye only equipped the armor with a laser weapon system, but even so, relying on the small and flexible characteristics of the armor, under Jin Ye's control, it was not a big problem to use the Douzhan No. 1 armor to drag the two county-level spaceships.

Xiao Yu has already begun an intense decoding work, trying to translate the signal carried in this radio wave into a language that he can understand. At the same time, Xiao Yu secretly prepared all laser cannons, high-velocity machine guns, hydrogen bombs, etc., ready to fight at any time.

Under such circumstances, Xiao Yu could not escape. Because now, that civilization should not have discovered Xiao Yu and Jin Ye's Water Blue Star Fleet, and if it escapes, it means starting the nuclear fusion engine to change the movement state of the spacecraft, and as soon as the nuclear fusion engine starts, it will emit a bright tail flame and strong radiation, and it is almost certain that it will be discovered by the other party, and then the enemy is in the dark, and he is in the light, he will become a bright target.

Xiao Yu can only rely on the ship's own inertia to navigate.

Ten days have passed, and during this time, everything is quiet as usual, Xiao Yu just waits in silence, preparing in silence. Unlike Xiao Yu, Jin Ye couldn't keep his nerves on to prepare for battle, which would be too exhausting, so he chose to meditate silently in the battle armor.

Then, Xiao Yu received a second message. This message still shows obvious logical characteristics. These two information receptions finally allowed Xiao Yu to make a rough positioning for the information emission source.

At the same time, after a lot of calculations, Xiao Yu came to a conclusion that this unknown information emission source was also approaching Tianyuan 4, but its speed was only 546 kilometers per second. According to this rate, two and a half days later, Xiao Yu will come into contact with him.

So the question is, do you want to fight this civilization? or just run away.

Xiao Yu fell into deep thought, and after three hours, after a lot of analysis, two pieces of information were cracked.

"The 7 survey satellite is running out of fuel, with a speed of 13.5 kilometers per second, and the detection module has been shut down, requesting instructions for the next step. ”

"The 7th survey satellite has successfully deorbited, and the communication module is about to be shut down, please confirm. ”

What is the special meaning behind these two pieces of information?

A large amount of computing power was called up by Xiao Yu to think about this problem.

From the literal analysis, this is a device called "Sky Survey Satellite 7", which communicates with a console somewhere. This satellite-like instrument is discarded after the fuel is exhausted. Then it can be known that in the eyes of this civilization, the cost of recycling this instrument is higher than the instrument itself.

This point made Xiao Yu confused. Since the interstellar voyage is launched, it is inevitable to reserve a large amount of fuel.

There are too many components that can be recycled on a normal operating instrument, and it is generally more reasonable to recycle the usable parts on it instead of throwing them away.

"It seems that the fleet of this civilization is in an energy crisis, and only this is explained. Xiao Yu thought silently, his mood heavy.

Now that this civilization is in an energy crisis, Xiao Yu is in danger. Because this civilization is likely to rob the Aqua Blue Star fleet for fuel and energy.

There is another piece of information, "The speed is thirteen.5 kilometers per second", which also confused Xiao Yu.

"Thirteen.5 kilometers per second?" Xiao Yu thought, "Since the speed is indicated, there must be a reference, so what is this instrument moving relative to?" Normally, it will take at least a year for an instrument to run out of fuel, and it can fly a distance of 400 million kilometers for such a long time, but from the strength of the signal I received, this signal cannot be received by the console 400 million kilometers away. ”

"This contradiction can only be explained by the fact that the instrument is moving in a circular motion around the console. Xiao Yu manipulated the huge computing power and made many calculations in an instant. "But in this case, a new contradiction will arise, under what circumstances will a fleet, need a satellite with a speed of thirteen.5 kilometers, revolving around it all the time?"

Xiao Yu has already calculated that only a star with a mass of 1.6 times that of the Earth will have an orbital speed of 13.5 kilometers.

"Could it be that the total mass of this fleet is 1.6 times that of the earth? That's why a special instrument is needed to monitor the situation of the fleet at any time? No, it can't be, the fleets have their own communication systems with each other, so why do they have to get a satellite out? Moreover, how can such a huge fleet not recover the fuel of a satellite?"

Xiao Yu was shocked, puzzled, he couldn't, he could only contact Jin Ye and listen to Jin Ye's thoughts.

Jin Ye himself had a certain understanding of the plot, and with the existing information, he already had a general idea in his heart in a moment.

Jin Ye thought for a while and said, "First of all, it can be determined that they have not mastered super-distance communication, that is, in terms of quantum theory, they are not as deep as me. Then, on the energy side, the first message says that the fuel is running out, and then it runs for another ten days before the communication module is turned off, so we can make some speculations about the fuel utilization rate. ”

Xiao Yu followed Jin Ye's train of thought and calculated: "Let's assume for the time being that the instrument is in a circular motion, mainly relying on inertia to maintain its orbit, and from the point of view of its abandonment, its mass cannot be too large, otherwise it cannot be abandoned so easily, for the time being, assume that its mass is ten tons, and then assume that its fuel is only 0.1 percent left, then, from the perspective of comprehensive analysis, ......."

"They're still fusion energy. ”

"In this way, the other party and ours should be at the same level of civilization. Jin Ye nodded and continued to speculate: "The other party's sailing speed is only five hundred and forty-six kilometers per second, and the speed we can reach is far more than this number. ”

"Then it means that the maneuverability of our fleet is far greater than that of the other party!" Xiao Yu seemed to think of the key, just like the navy evaluates the combat effectiveness of frigates on the water, maneuverability is also a manifestation of combat effectiveness on the spaceship.

"But how can the other party build such a large spaceship? It takes a satellite to observe its own hull?" Xiao Yu is still puzzled, the size of the battleship is also a manifestation of the strength of civilization, according to common sense, it is impossible to make such a huge hull in terms of engine power at such a low level.

"So is there a possibility that the other party is not a fleet at all, but a civilization developed by a planet wandering in the universe?" Jin Ye thought of the plot he got and said his thoughts.
