The method of destroying enemy detectors is very simple. It is still the same ejection device used to launch interstellar missiles, but the interstellar missiles are replaced with conventional high-explosive ammunition. It is a bit wasteful to use hydrogen bombs to deal with such small things.
After calculating the trajectory, Xiao Yu aimed at the instrument and launched the ammunition.
Seventy seconds later, the high-explosive ammunition passed through a distance of several thousand kilometers and met the alien civilization's detection instrument head-on. Then, the preset detonation device was activated, and the ammunition was detonated, bursting into a ball of fire in the air.
, the detection instrument was like a kite with its string broken, spinning in circles and not knowing where it had been.
Time is getting increasingly urgent. Although this instrument did not detect Xiao Yu, Xiao Yu cannot guarantee whether the next instrument will find him before he discovers it. It is like hanging above his head at any time.
A sharp sword can cut you down at any time.
This feeling of being threatened at any time is not good.
The two civilizations in the dark universe are both trying to find each other first. Whoever finds the other first will have a huge advantage. In the subsequent collision of the two civilizations, the winning rate can be increased by at least thirty
percentage point.
The current situation is not optimistic.
The other party has found an effective method, but Xiao Yu has not found his own method yet.
The method of releasing some detectors to wander randomly in space can be used by the other party, but Xiao Yu cannot. The reason is very simple. To achieve effective signal coverage and adapt to a huge search area, God knows how many detectors are needed. The other party has
With our own planet as a material base, the other party can obtain unlimited materials and build so many detectors, but Xiao Yu only has a fleet. Xiao Yu's materials are limited and cannot be compared with the other party.
Xiao Yu must find another way to fight against the opponent, otherwise, Xiao Yu can only pray for his good luck to prevent himself from being discovered by the opponent. However, luck can be good for one year, ten years, or fifty years.
What about a hundred years?
There are still several thousand years before reaching the Tianyuan Four Star System. Moreover, Xiao Yu cannot guarantee that he will be able to defeat the opponent after reaching the Tianyuan Four Star System.
Xiao Yu continued to make calculations. Under Chen Mo's gaze, he suppressed his self-destruction and made calculations patiently.
He didn't know how many times he had failed, nor how much time had passed. Xiao Yu only knew that during this period of time, he had destroyed at least ten more enemy detectors.
Gradually, Xiao Yu's eyes brightened.
Xiao Yu thought of a method. This method has passed the 40,000 detection obstacles set by Xiao Yu. This proves that this plan is feasible. Moreover, this plan does not involve a certain amount of luck like the other party's method.
, but, as long as it takes a certain amount of time, Xiao Yu can definitely find the other party.
Just like launching a large number of detectors to randomly search for this method, the other party can use it, but Xiao Yu cannot use it. Similarly, Xiao Yu can use this method, but the other party cannot.
That is, gravitational lensing.
The concept of gravitational lensing was first proposed and predicted by Einstein, the greatest scientist in human history. Simply put, gravitational lensing means that when starlight passes around a massive star, the light that originally travels in a straight line will be
It is bent due to the gravity of the massive star, which looks like a slight shift in the position of the protostar.
Xiao Yu knew that the mass of this alien civilization's planet was greater than that of the earth. It was certain that gravitational lensing would also occur around this planet.
However, on a cosmic scale, the mass of this planet is still too small, and the gravitational lensing effect may be negligible, which means that an instrument with a very high precision is needed to observe in which direction the gravitational lensing phenomenon occurs.
The next thing is very simple. As long as Xiao Yu observes which direction the gravitational lensing phenomenon occurs, and then through a series of precise calculations, he can calculate the opponent's position.
This is also the reason why Xiao Yu can use this method, but the other party cannot. Although Xiao Yu's fleet has a total mass of tens of millions of tons, compared with a planet, it can be regarded as an ant and can be ignored.
It is so difficult to observe the gravitational lensing phenomenon of a planet, let alone the gravitational lensing of Xiao Yu’s fleet.
At least, Xiao Yu estimated that a civilization that is thousands of years ahead of his own technology may be able to observe it, but this alien civilization definitely does not have this ability.
The position of the original star in the sky has been recorded in Xiao Yu's Sky Record of Heroes. The shifted position can be obtained through current observations. What Xiao Yu has to do is very simple, that is, all visible stars in the entire sky
Conduct the observation again, and then compare it with the data in the Sky of Heroes record to see where the starlight has shifted.
However, it is easy to say but not easy to do. This requires extremely high-precision observation instruments and a huge amount of data calculation.
Xiao Yu prepared for half a year to do this.
Countless data were collected into the central computer. After being processed by the central computer, the results were compared with the original data in the Heroes' Sky Record. One star after another was eliminated by Xiao Yu.
Every star that is excluded proves that there are no traces of enemies in this direction. Gradually, Xiao Yu's search range becomes smaller and smaller.
After the past three months, Xiao Yu's search range of 360 degrees in the entire sky has been reduced to a range of 160 degrees in less than half of the sky.
The next star to be measured is a star located in the constellation Canis Major, which humans usually call Military City One.
Junshi 1 is five hundred light years away from the sun. Before, humans had no detailed data about Junshi 1. However, when compiling the Sky Records of Heroes, Xiao Yu measured Junshi 1 and collected its mass and volume.
, spectral type and other data.
As soon as Jiangjun City observed it again, Xiao Yu began to analyze its various data, and then compared it with the original data.
"Huh?" When comparing, Xiao Yu found an extremely small gap.
After removing the error caused by the movement of its own position, Junshiyi's position is slightly offset from the original position, and its right ascension and declination are approximately 19 millionths of a degree higher than the original position.
offset.
Xiao Yu immediately caught this message and immediately started a second review.
The results of the re-examination came out quickly, and the conclusion reached remained unchanged. Military Market 1 indeed had an unexplained slight deviation.
After eliminating all possibilities, the only explanation was that the alien planet was hidden somewhere between him and Junshiyi.
Xiao Yu became excited, and immediately took Junshi Yi as the center of the circle and measured several stars on the celestial sphere and around Junshi Yi. The results showed that the stars around Junshi Yi had all undergone changes in size.
Unequal offsets.
"Okay, I finally found you." Xiao Yu murmured, feeling extremely excited.
With these data, Xiao Yu calculated the specific location of the alien planet in only thirty seconds.
They are located in the direction of Canis Major, about 32 million kilometers away from Xiao Yu.
"It's disrespectful to come back without reciprocating. If you launch a detector to find me, I will launch a hydrogen bomb and return it to you...just wait and see!"
Xiao Yu immediately prepared for launch and launched a large-yield hydrogen bomb. It is expected that in three months, the hydrogen bomb will reach the predetermined location and then explode.
After searching for more than a year, Xiao Yu found the other party. The anger that had been suppressed for a year suddenly burst out. Xiao Yu couldn't wait to see the scene of the hydrogen bomb explosion and express his resentment.
However, Xiao Yu's behavior was still under rational control. Xiao Yu deliberately launched the second batch of hydrogen bombs ten days after the first one was launched. This batch of hydrogen bombs contained a total of twenty.
After five days of silence, Xiao Yu launched the third batch of twelve hydrogen bombs.
Xiao Yu deliberately made his launch time and launch quantity irregular. In this way, the opponent would not be able to organize effective interception methods, and they would become frightened birds, always worried about the attack of the hydrogen bomb, and always living in the shadow of the hydrogen bomb attack.
Next. Because they never know when the next hydrogen bomb will arrive.
"Enjoy the hydrogen bomb feast, you bastards!" Xiao Yu thought viciously.
In three months, Xiao Yu launched a total of about 300 hydrogen bombs. Even if only 30 of these 300 hydrogen bombs could explode, it would bring extremely powerful radiation disaster to the planet.
Xiao Yu even made an estimate that if a hydrogen bomb of the same magnitude exploded on the earth, the radiation hazards caused by it would cause various cancers, infant deformities, etc., and the human population would collapse within a hundred years.
The population of 7 billion has dropped to less than 100 million.
This basically means the annihilation of the race. Of course, Xiao Yu does not know the body structure, radiation resistance level, etc. of these aliens, but judging from their panicked response last time, they are also very afraid of these hydrogen bombs.
"Blow it up, blow it up." The scheduled explosion time has come. Xiao Yu's eyes lit up and he nervously stared at the calculated direction of the planet.
In the distance, a faint burst of light suddenly burst out. It was fleeting and its brightness was not even as bright as some distant and dim stars. But that planet was more than 30 million kilometers away from Xiao Yu, and even though it was so far apart
Even at a long distance, the light it emits can still be observed by Xiao Yu, and its intensity can be imagined.
Xiao Yu felt excited and immediately calculated it.
The calculation results show that this burst of fire was the first hydrogen bomb launched by Xiao Yu!
Under this burst of firelight, Xiao Yu also observed the faint light reflected by the planet.
This shows that everything is as Xiao Yu expected! Their planet is indeed at that location.
