Super Battleship Reborn

Chapter 40 The method of gravitational lensing to destroy enemy detectors is very simple. It is still the kind of ejection device used to launch interstellar missiles, but the interstellar missiles are replaced by conventional high-explosive ammunition. To deal with such small things, if you use hydrogen bombs A bit of a waste.

After calculating the trajectory, Xiao Yu aimed at the instrument and fired the ammunition.

Seventy seconds later, the high-explosive ammunition traveled a distance of several thousand kilometers and met the detection instruments of the alien civilization head-on. Then, the pre-set detonating device was activated, the ammunition was detonated, and a burst of fire broke out in the air. , the detection instrument was like a kite with a broken string, spinning in circles not knowing where it was going.

Time is getting tighter. Although this instrument did not find Xiao Yu, Xiao Yu could not ensure that the next instrument would find himself before he found it. It was like a sharp sword hanging over his head at any time, which could be cut off at any time.

This feeling of being threatened at any time is not good.

The two civilizations in the dark universe are trying to find each other first. Whoever finds the other side first will have a huge advantage. In the subsequent collision of the two major civilizations, the winning rate can be increased by at least 30%.

The current situation is not optimistic.

The other party has found an effective method, but Xiao Yu has not found his own method.

The method of releasing some probes to wander randomly in space, the other party can use it, but Xiao Yu can't. The reason is simple, God knows how many detectors are needed to achieve effective signal coverage and accommodate a large search area. The other party has his own planet. With his own planet as the material base, the other party can obtain unlimited materials and can build so many detectors, but Xiao Yu has only one fleet. Xiao Yu's materials are limited and cannot be compared with each other.

Xiao Yu must find another way to fight against the opponent, otherwise, Xiao Yu can only pray for his good luck so that he will not be discovered by the opponent. However, what about luck for one year, ten years, fifty years, or one hundred years?

There are still thousands of years before reaching the Tianyuan four galaxies. Moreover, Xiao Yu could not guarantee that after reaching the Tianyuan four-star system, he would definitely be able to defeat the opponent.

Xiao Yu continued to make calculations. Under Chen Mo's watch, he suppressed his self-defeating mentality and made calculations patiently.

I don't know how many times I failed, and I don't know how much time has passed. Xiao Yu only knew that within this period of time, he had eliminated at least ten more detectors from the enemy.

Gradually, Xiao Yu's eyes brightened.

Xiao Yu thought of a way. 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 have a certain element of luck like the other party's means, but, as long as it takes a certain amount of time, Xiao Yu will definitely be able to find the other party.

It's like launching a large number of detectors to randomly search for this method. The other party can use it, but Xiao Yu can't use it. Similarly, this method, Xiao Yu can use it, but the other party can't.

That is, gravitational lensing.

The concept of gravitational lensing was first proposed and predicted by Einstein, the greatest scientist in human history. In simple terms, gravitational lensing means that when starlight passes around a massive star, the light that originally propagated in a straight line will The gravitational force of the massive star is bent, and it appears as if the position of the original star has shifted slightly.

Xiao Yu knew that the planet of this alien civilization had a mass greater than that of the earth. To be sure, gravitational lensing also occurs around this planet.

However, on a cosmic scale, the mass of this planet is still too small, and the effect of gravitational lensing may be minimal, which means that a very high-precision instrument is required to observe which direction gravitational lensing occurs.

The next thing is very simple,

As long as Xiao Yu observed the gravitational lensing in which direction, and then through a series of precise calculations, he could calculate the opponent's position.

This is also the reason why Xiao Yu can use this method, but the other party cannot. Xiao Yu's fleet, although the total mass is as high as tens of millions of tons, but compared with a planet, it can be regarded as an ant that can be ignored. And it is so difficult to observe the gravitational lensing of a planet, let alone the gravitational lensing of Xiao Yu's fleet.

At least, Xiao Yu estimates that civilizations that are thousands of years ahead of their own technology may observe them, but this alien civilization must not have this ability.

In the sky, the position of the original star has been recorded in Xiao Yu's Qunying Sky Record. The offset position can be obtained by observing it now. What Xiao Yu has to do is to re-observe all the visible stars in the entire sky, and then compare it with the data in the Qunying Sky Record to see where the starlight has shifted.

But it's easier said than done. 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, and after the central computer was calculated, the results were compared with the original data in the Qunying Heaven Records, and one star after another was excluded by Xiao Yu.

Every excluded star is proving that there is no trace of the enemy in this direction. Gradually, Xiao Yu's search scope became smaller and smaller.

The search range of 360 degrees in the whole sky domain has been narrowed down by Xiao Yu to less than half the sky domain, within a range of 160 degrees after the past three months.

The next star to be measured is a star in the constellation Canis Major, commonly known as Military One.

Junshiyi is 500 light-years away from the sun. Humans did not have detailed data on Junshiyi before, but when compiling the record of the heroic sky, Xiao Yu measured Junshiyi and collected its mass and volume. , spectral types, etc.

As soon as the General 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, the position of Junshi 1 is a little bit shifted from the original position, and its right ascension and declination are about 19 millionths of a degree from the original position. offset.

Xiao Yu immediately caught this message and immediately started the second review.

The results of the re-examination came out soon, and the conclusions still remained unchanged. Military market one, there is indeed an unexplained slight shift.

After eliminating all possibilities, the alien planet, hidden somewhere between himself and the military city, became the only explanation.

Xiao Yu became excited, and immediately took Junshi 1 as the center of the circle, and measured several stars around Junshi 1 on the celestial sphere. unequal offsets.

Okay, I finally found you. Xiao Yu muttered, feeling extremely excited.

With these data, Xiao Yu calculated the exact 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.

Come and don't be indecent, you launch probes to find me, and I will launch a hydrogen bomb back to you... wait and see!

Xiao Yu immediately prepared for the launch and ejected a large-yield hydrogen bomb. It is expected that after three months, the hydrogen bomb will reach the predetermined position 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 burst out instantly, Xiao Yu couldn't wait to see the picture of the hydrogen bomb exploding, and let out a breath of resentment.

However, Xiao Yu's behavior is still under rational control. Xiao Yu deliberately launched the second batch of hydrogen bombs ten days after the first hydrogen bomb was launched. There were 20 hydrogen bombs in this batch.

Then there was five days of silence, and Xiao Yu fired a third batch, twelve hydrogen bombs.

Xiao Yu deliberately made his launch time and number irregular, so that the other party could not organize effective interception methods, and they would become frightened birds, always worrying about the attack of the hydrogen bomb, and always living in the shadow of the hydrogen bomb. Down. Because they never know when the next hydrogen bomb will come.

Enjoy the hydrogen bomb dinner, bastards! Xiao Yu thought fiercely.

In three months, Xiao Yu fired a total of about 300 hydrogen bombs. Of these 300 hydrogen bombs, even if only 30 can explode, it will bring extremely powerful radiation disaster to that planet.

Xiao Yu even made an estimate that if a hydrogen bomb of the same equiv- Seven billion people, down to less than 100 million.

This has basically meant the genocide of the dead. Of course, Xiao Yu didn't know the body structure and radiation resistance level of these aliens, but judging from their panicked response last time, they were also very afraid of these hydrogen bombs.

Blow it up, blow it up. It was already the scheduled time for the explosion, Xiao Yu's eyes lit up, and he stared nervously at the projected direction of the planet.

In the distance, a faint burst of light suddenly burst out, and it was fleeting, and its brightness was not even comparable to some distant dim stars. But that planet is more than 30 million kilometers away from Xiao Yu, and even if it is so far apart, the light it emits can still be observed by Xiao Yu, and its intensity can be imagined.

Xiao Yu was excited for a while, and immediately calculated it.

The calculation results show that this burst of fire is the first hydrogen bomb launched by Xiao Yu!

Under the light of this fire, Xiao Yu also observed the faint light reflected by the planet.

This shows that everything is as Xiao Yu expected! Their planet is indeed in that location.
