The method of destroying enemy probes is very simple, it is still the kind of ejection device used to launch interstellar missiles, but the interstellar missiles have been replaced with conventional high-explosive ammunition, which is a bit wasteful 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 munition traveled thousands of kilometers and met head-on with the detection instruments of the alien civilization, and then, the pre-set haode detonating device was activated, the munition was detonated, and a ball of fire exploded in the air, and the detection instrument, like a kite with a broken string, turned in circles and did not know where it was dried.

Time is getting tighter. Although this instrument did not find Xiao Yu, Xiao Yu was not sure that the next instrument would not find itself before he discovered it. It's like having a sharp sword hanging from the top of your head at any time, ready to be cut down at any moment.

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 great advantage, and in the subsequent collision of the two civilizations, the winning rate can be increased by at least thirty percentage points.

The current situation is not optimistic.

The other party has found an effective means, but Xiao Yu has not yet found his own way.

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

Xiao Yu must find another way to confront the other party, otherwise, Xiao Yu can only pray for his good luck so that he will not be discovered by the other party. But what about a year of luck, 10 years, 50 years, 100 years?

There are still thousands of years to go before reaching the four galaxies of Tianyuan. Moreover, Xiao Yu could not guarantee that after reaching the Tianyuan Four Star System, he would definitely be able to defeat the other party.

Xiao Yu continued to calculate, under Chen Mo's gaze, suppressed his self-abandonment, and patiently carried out the calculation.

I don't know how many times I've failed, and I don't know how much time has passed. Xiao Yu only knew that during this period of time, he had eliminated at least ten or 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 barriers set by Xiao Yu. This proves that this jihua is feasible. Moreover, this jihua is not like the other party's means, there is a certain element of luck, but as long as it takes a certain amount of time, Xiao Yu will definitely be able to find out the other party.

It's like sending a large number of probes around to find this method randomly, the other party can use it, Xiao Yu can't use it, the same, this method, Xiao Yu can use it, but the other party can't use it.

That is, gravitational lensing.

The concept of gravitational lensing, first proposed and predicted by the greatest scientist in human history, Albert Einstein, simply put, gravitational lensing means that when the starlight passes around the massive star, the light that originally travels in a straight line will be bent due to the gravitational pull of the massive star, and it looks as if the position of the protostar has shifted slightly.

Xiao Yu knew that the mass of this alien civilization on the planet was even greater than that of the earth. It is certain that around this planet, gravitational lensing also occurs.

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 it requires very high-precision instruments to observe which direction gravitational lensing occurs.

The next thing is very simple, as long as Xiao Yu observes which direction the gravitational lensing phenomenon occurs, and then after a series of precise calculations, the position of the other party can be calculated.

This is also the reason why this method can be used by Weishenme Xiao Yu, but the other party cannot use it. Xiao Yu's fleet, although the total mass is tens of millions of tons, compared to a planet, it can be regarded as negligible ants. And it is still so difficult to observe the gravitational lensing phenomenon of a planet, let alone observe the gravitational lensing of Xiao Yu's fleet.

At least, Xiao Yu estimates that a civilization that is thousands of years ahead of his own technology may be observed, but this alien civilization definitely does not have this ability.

In the sky, the position of the protostar has been recorded in Xiao Yu's Heroic Sky Record. The offset position can be found by observing it now. What Xiao Yu has to do is very simple, that is, to make a new observation of all the visible stars in the whole heavenly area, and then compare it with the data in the Heroes Sky Catalog 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 computation.

Xiao Yu prepared for half a year to do this.

Countless data were collected into the central computer, and after the central computer calculated, the results were compared with the original data in the Heroes Sky Record, and one star after another was eliminated by Xiao Yu.

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

The search range of three hundred and sixty degrees in the whole heavenly domain has been narrowed down by Xiao Yu to less than half a heavenly domain, one hundred and sixty degrees after the past three months.

The next star to be measured is a star in the constellation Canis Major, commonly referred to by humans as Gunshi One.

Junshi 1 is 500 light-years away from the sun, and there is no detailed data about Junshi 1 before, but when compiling the Qunying Sky Record, Xiao Yu measured Junshi 1 and collected data such as its mass, volume, and spectral type.

As soon as General City re-observed, 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 his position, the position of Junshi No. 1 is a little offset from the original position, and its right ascension and declination are about 19 millionths of a degree away from the original position.

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

The results of the review were quick to come out, and the conclusions reached remained unchanged. The military market one, inexplicably small shifts have indeed occurred.

After ruling out all possibilities, the alien planet, hidden somewhere between itself and the military market, became the only explanation.

Xiao Yu's mood became excited, and he immediately took Junshi No. 1 as the center of the circle, and measured several stars above the celestial sphere and around Junshi No. 1, and the results showed that several stars around Junshi No. 1 had shifted in different sizes.

"Well, Lao Tzu has finally found you." Xiao Yu muttered, extremely excited in his heart.

With this data, Xiao Yu only calculated for thirty seconds to calculate the specific location of the alien planet.

They are located in the direction of Canis Major, about 32 million kilometers away from Xiao Yu.

"Come and don't be rude, you send a probe to me, and I will launch a hydrogen bomb to return it to you...... Wait and see! ”

Xiao Yu immediately prepared for launch, and ejected a high-yield hydrogen bomb, which is expected to reach the predetermined position and explode in three months.

After searching for more than a year, Xiao Yu found the other party. The anger that had been suppressed for a year exploded instantly, and Xiao Yu couldn't wait to see the picture of the hydrogen bomb explosion and let out a sigh of resentment.

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

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

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

"Well haode enjoy a hydrogen feast, bastards!" Xiao Yu thought viciously.

In three months, Xiao Yu launched a total of about 300 hydrogen bombs. These 300 hydrogen bombs, even if only 30 can explode, will bring extremely powerful radiation disasters to that planet.

Xiao Yu even made an estimate that if a hydrogen bomb of the same yield exploded on the earth, the radiation hazards caused by various cancers and infant deformities would reduce the human population from 7 billion to less than 100 million within 100 years.

This basically means that the dead race is extinct. Of course, Xiao Yu didn't know the body structure of these aliens, the level of radiation resistance, etc., but judging from their panicked response methods last time, they were also very afraid of these hydrogen bombs.

"Fry it, fry it." It was already the scheduled explosion time, Xiao Yu's eyes lit up, and he stared nervously at the direction of the planet in the calculation.

In the distance, a faint burst of light suddenly burst out, fleeting, and its brightness was not even comparable to some distant and faint 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 in his heart, and immediately calculated it.

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

Under the reflection of 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, indeed, is in that location.
