This question, which Xiao Yu ignored, is actually very simple, that is, what is the ghost heart?

Does it have mass, does it have volume, how big is it, and what does it look like?

Xiao Yu has no answers to these questions. It seems that subconsciously, Xiao Yu thinks that something as special as the ghost heart can be easily discovered as soon as he comes to this star system.

But now, Xiao Yu knew he was wrong. And it's ridiculously wrong.

What was presented in front of Xiao Yu was an extremely chaotic situation. You know, the planet that was destroyed by the fish in the pond and blown up by the stellar cannon has a lot of water.

Matter does not disappear out of thin air, nor does it appear out of thin air, even if the planet explodes, its constituent matter is still the same substance, and water is still water, at most it changes into hydrogen and oxygen. Under the illumination of this extremely unstable star, whose radiation intensity is hundreds or thousands of times more intense than usual, water will sublimate and condense.

Therefore, what is presented in front of Xiao Yu is such a picture. In front of Xiao Yu, there are endless asteroids and rubble. These asteroids and rubble are of various sizes, ranging from hundreds of billions of tons of mass to a few grams of small ones. They have formed a new asteroid belt that is revolving around the star.

The mass of this planet is larger than that of the Earth, and according to the mass of a fragment of 100 million tons, after the explosion of this planet, it is enough to form tens of trillions of fragments. What's more, most of the fragments here are extremely tiny?

In this case, the number of fragments here is not more than tens of trillions? Their number is almost like the number of sand in the Ganges, and there is no way to calculate it.

If that's not an obstacle either, then ...... by water. What about the tail of a comet formed by volatile objects such as carbon dioxide, methane, liquid hydrogen, and liquid oxygen?

At the moment, most of the asteroids here are shrouded in the tail of the comet, which will cause a great obstruction to visible light, and at the same time, because it is too close to the star, infrared detection methods cannot be used.

So...... How do you find that ghost heart in so many fragments? What's more, Xiao Yu didn't know what the Ghost Heart was like at all.

It's just an impossible task.

Look at the chaotic galaxy in front of you. Xiao Yu's heart was full of chagrin.

"How so, how so?" Xiao Yu muttered to himself, thinking quickly in his mind, "Hateful." Why didn't I think of this question before, and didn't ask it clearly while the Ghost Clan's predecessors were still alive. My companion Ghost Clan may also know some clues. But I forgot to ask about it? ”

This mistake is really undeserved. Xiao Yu was very annoyed in his heart, but after the chagrin, Xiao Yu still began to think about how to solve this problem.

"It's already happened, and it's useless to regret it, so let's think about how to face the predicament in front of you. Kindness...... Since the predecessors of the ghost clan left this ghost heart to me. Then it certainly won't put some obstacles in my way that I can't solve. If this ghost heart was as tiny as dust, then even a sixth-level civilization would not be able to find it among the sand-like fragments of the Ganges. ”

"Then you can be sure of the appearance of the Ghost Heart. It will definitely not resemble these asteroids, and it will not be hidden inside these asteroids. Because then I wouldn't have been able to find it out. ”

"This asteroid belt, which is hundreds of millions of kilometers long and thousands to tens of thousands of kilometers wide and high, is ...... There's no way, let's take the most primitive way. Xiao Yu silently calculated in his heart and began his own actions.

It's really primitive, but it's also very practical. Theoretically, as long as there is enough time, Xiao Yu will definitely be able to find out the ghost heart. However, there was another problem, Xiao Yu was not sure how much time he had and whether he could escape smoothly before the fleet of the Molian civilization chased after him.

"Time...... Set at five years. If you still can't find the Ghost Heart within five years, simply give it up and look for it later. Anyway, if I can't find it, I won't be able to find the Murlian civilization. Xiao Yu thought and made up his mind.

The solution is simple, that is, to create an extremely large number of robots scattered in this asteroid belt to find them. This move is like an idiom, looking for a needle in a haystack, but the number of people involved is a little more.

"Let's revamp the current machinery first, ...... The manufacturing method of a probing robot is simple...... Well, the manufacturing drawings have been designed, and at the current stage, it is too late to use reserve materials for manufacturing and build large-scale mining, and the ore training base. Damn it, if I had asked in the morning, where was there such trouble. Xiao Yu started his work with some chagrin.

In Xiao Yu's huge fleet, because there is no need to carry life-sustaining equipment and reserve space for biological activities, at least more than half of the spaceships have loaded these saved spaces with various materials and mechanical processing equipment. The huge construction force required to build a huge number of robots is not a problem for Xiao Yu at all.

Under Xiao Yu's manipulation, countless mechanical equipment began to operate, and many microrobots with elemental decay and antimatter mixing engines began to be created. They will be able to move freely through the chaotic asteroid belt, and will be able to replenish them on the spot when they run out of fuel. At the same time, in order to solve the communication problem with these microrobots, Xiao Yu also created a lot of satellites scattered in the asteroid belt.

Half a month after arriving in this galaxy, the first microrobots set off.

Under Xiao Yu's control, the first batch of 100 million microrobots flew out of the exits of each spaceship, like a handful of sand sprinkled into the sea, and quickly integrated into the chaotic asteroid belt. These microrobots will detect all material with a radius of more than half a centimeter, and if it is indeed an asteroid, the microrobots will make a mark on them to indicate that the asteroid has been explored, and the rest of the microrobots will not waste time on the asteroid again.

This means an extremely large data exchange, as well as an unimaginably large database system. But because all of this data can be done with automated analysis programs, they don't take up the computing power of Xiao Yu's flagship, the Beijing.

In order to cope with these data needs, Xiao Yu simply made a sophisticated distributed program, and shared these data in the central computers of Tianjin, Chongqing, Shanghai, Hebei and other provincial spacecraft. Several provincial spaceships have joined forces to finally eat up this huge demand for computing power.

If an asteroid is found to be somewhat peculiar, the microrobot will make further observations of it and pass these observations to Xiao Yu for further analysis. Xiao Yu will not let go of any suspicious target.

Time flies by, and half a year later, more than 10 billion microrobots and tens of thousands of communication satellites have been active in the asteroid belt. These devices together form a big net, and in this sea of stars, they are trying their best to find a "needle" that is very important to Xiao Yu.

So far, Xiao Yu has still found nothing. Yes, although more than ten trillion asteroids have been explored, Xiao Yu still hasn't found what he wants. But Xiao Yu had some other gains.

"Huh? Another piece? Quality...... It's about eight kilograms, okay, recycled. After receiving a message, Xiao Yu quickly responded, assigning another recycling robot to rush here and grab a piece of black stuff in his hand.

That's right, these things are the wreckage of the primary star cannon that caused the explosion and disintegration of this planet. Xiao Yu didn't forget that at the beginning, in order to make this stellar cannon, he threw all the flesh and blood of the white dwarf alien beast into it. These things contain at least seventy percent of the flesh and blood of alien beasts, and their effect on Xiao Yu is self-evident.

"It's been half a year, and even the flesh and blood of alien beasts have been recovered piecemeal, but Ghost Heart, where are you?" Xiao Yu thought a little depressed.

During this time, in addition to finding the Ghost Heart, Xiao Yu also carried out other work, that is, the upgrade, transformation, and repair process of the existing spaceship. In fact, these works have been going on all along, but they have not been carried out on a large scale due to time constraints and material shortages.

Time is still slipping away bit by bit, and every second that passes, the sense of crisis in Xiao Yu's heart becomes a little heavier.

"That's a good thing...... Are diamonds formed during the explosion of the planet? It's worth a lot of money, but it's not useful to me. ”

"Huh? Such a big piece of gold? Still useless......"

Xiao Yu analyzed the data one by one, feeling a little bored.

Diamonds, gold, in the age of the earth, are priceless treasures, but here in Xiao Yu, there is no way to even let Xiao Yu go out and recycle them.

In the midst of this boring process, suddenly, another message was transmitted to Xiao Yu.

The information that can be transmitted to Xiao Yu is filtered by the automated program, and Xiao Yu is trying his best to reduce his burden, but the automated program will have shortcomings after all, which will still cause a lot of useless information to be transmitted to Xiao Yu, just like that diamond, just like that piece of gold.

However, this message does not seem to be the same as those things...... (To be continued......)
