By the time all the disinfection was completed and Su Ruyu confirmed that it was safe, Lu An had already been wearing a wet space suit and had been sitting in the isolation room for two hours.

Although he knew that Su Ruyu was deliberately "punishing" himself, Lu An still had to accept her order, and only after Su Ruyu signaled did he step on the water trail and return to the cockpit.

At this time, Su Ruyu had already drawn a three-dimensional map of the 273 asteroid, and when she saw Lu An coming in, she said without raising her head: "It just so happens that where did you see that person just now?" ”

Lu An rubbed the droplets of water on his face while pulling the inner lining of the spacesuit that was dripping water, and replied, "Oh, it's about three kilometers from us on the way to the previous landing site." ”

"Are there any specific coordinates?"

Lu An raised his wrist, shook the water droplets on Zhi's brain, called up the information of the holographic projection, and then pointed: "This is the route of travel, it seems that there are no specific coordinates." ”

"Oh, by the way, I just looked in the cockpit and the isolation pod, and there is no obvious bacterial spore reaction, so there should be no problem for the time being." Su Ruyu replied without raising her head.

"Uh, that means we've been tossing around for so long?"

"What if I'm talking about a spore reaction?" After Su Ruyu glanced at him, he said: "You clean up first, replenish some water and energy, take a little rest, and take me over to take a look later, I have to see it with my own eyes to rest assured, and record some useful information by the way." ”

"Okay, I'll go change my clothes."

An hour later, the two men were back on the road and quickly disappeared near the patrol boat, which had been scrapped as a "space station", blending into the darkness around them.

……

"The seventh."

"I knew we should have taken the opportunity to scan the holographic stereo of this asteroid in the first place, and we wouldn't be so helpless now!"

"Who would have thought of this situation? At that time, I just wanted to escape quickly, and even if I couldn't escape, it was very likely that I wouldn't be able to come back, how could we have the heart to do such boring things at that time, and we weren't going to live on this asteroid. ”

"yes, I'm just talking, who would have thought this would be like this!"

After a short silence, Su Ruyu lowered her head again and said, "Now it's basically certain that we should go and find the possible spaceship." ”

"Hmm. However, if it is as we suspected, the situation of the ship should also be worrying......"

"I hope so."

Lu An continued to say worriedly: "Moreover, there is another warship in the sky......

"Well, let's find it first."

Now it has been more than two days since Lu An took Su Ruyu into the darkness on foot and found the first "person", and in these two days, Lu An and Su Ruyu have found six more "people" one after another, all of whom are dead people.

Su Ruyu speculated that these people should have been dead for more than ten years, and Lu An's discovery confirmed his speculation, because peeling off these people's space suits, the visible military uniforms had revealed enough information.

All seven of them were dressed in the uniforms of the Combined Space Fleet from the last war, a blue and white military uniform that symbolizes the earth and has been quietly changed after the last war. Today, with a few exceptions, such as the gendarmerie, most uniforms have been uniformly changed to white.

These men have been dead for more than a decade and are dressed in the uniforms of the Combined Space Fleet of the Earth headquarters in humanity's first interstellar war......

Based on these two points alone, Lu An could easily deduce that these people were likely to have suffered some accidents in the last war, whether they were lost, lost in battle, or ship-breakdown, in short, they came to this asteroid far from the central battlefield area, and somehow died here unharmed.

This made Lu An even more confused.

Why is there such a strange thing about the "death" of soldiers in this desolate area?

You must know that as the only sample of human interstellar warfare, the human interstellar war, which lasted for four years that ended ten years ago, has become a key example for military cadets to study since the beginning of the war.

Today's military logistics construction, starfleet composition, interstellar defense and offense, and many other fields have also continued to develop with reference to the successes and failures of all parties in the last war.

The Third Military Academy of the Earth Headquarters, where Lu An is located, is naturally no exception, although in many battle case analysis, Lu An has to endure that name appearing in his ears over and over again.

Therefore, he knows very well that asteroid 273 has never been the engagement area of the last war, in that war, the engagement area of the United Space Fleet and the Outer Planet United Defense Fleet, from the Lagrange point between the Earth and the Moon to the surface of the Moon, from the surface of the Moon to the outer space between the Earth and Fire, and then the "Titan" fortress of the asteroid belt, and finally it is just the bloodless, disarmed and surrendered outer orbital space of Europa.

None of these five regions is not hundreds of millions of kilometers away from asteroid 273, and the only asteroid belt "Titan" fortress with the same astronomical region name is almost on the back of the line between 273 and the sun, and it is even the farthest of the five regions.

So, isn't it strange that a warship under the United Space Fleet of the Earth headquarters suddenly appeared on asteroid 273, far away from the battlefield?

Of course, this made Su Ruyu's previous very nervous and anxious speculation come to naught, even if the Earth Headquarters was desperately conducting various secret experiments during the war at that time, it was impossible to use the 273 asteroid in the hinterland of Mars and asteroid belts as a "space graveyard"; Even if these soldiers are on an unspeakable secret mission and want to create any mass destruction effects, it is even more impossible to come to this barren and lonely asteroid, and the use of biochemical and genetic weapons should always go to a densely populated place!

What made Su Ruyu and Lu An even more puzzled was that as the search area expanded, these dead soldiers were found one after another. Without the holographic scanning of the spacecraft, Lu An and Su Ruyu collected information and intelligence on the asteroid on foot, and these strange discoveries were made during this time.

One may be accidental, two may be accidental, after all, maybe after some spaceship crashes, some remains will float far, far away, such a precedent is not unprecedented.

But what about three? What about four? What about five? What about six? Coupled with the seventh one that Lu An just discovered, and it was an accident, then Su Ruyu and Lu An's luck was too exaggerated, why did they fall here so unlucky?

Perhaps, there is no need to continue looking for other evidence, Su Ruyu and Lu An have already begun to look for the "wrecked warship" that is very likely to exist.

"How do we find it? This asteroid No. 273 is not big, but it is not small, with a diameter of more than 20 kilometers, and it is roughly estimated to have an area of 5,000 square kilometers. And, in case you run into a crater, or if there's dust buried, it's going to be found, tsk—"

Su Ruyu stared at the holographic stereoscopic image on the screen of the bridge and said worriedly.

Lu An crossed his arms and thought for a while that there was no good way, so he had to shrug his shoulders and say: "Anyway, we are trapped here now waiting for death, and there is nothing else to do, it's better to find it than to wait for death, right?!" ”

"Hey, why do you keep saying something deflating?"

"Uh, deflated? Isn't that the truth what I'm talking about? ”

"Hmph, aren't you a cadet? You seem to have said before that you are a student in the Department of Space Information Gathering and Confrontation, if you go to war in the future, will you deal with your boss like this? Are you going to tell your captain that people are going to die anyway, and it's better to fight now than to die, right? ”

Su Ruyu imitated Lu An's tone, so sarcastic.

Lu An pursed his lips and retorted, "Huh! First of all, I won't go to war in the future, how far will I hide! Besides, going to the battlefield is not looking for ......," Lu An said, and suddenly his voice weakened.

Well, it seems that on the battlefield, judging the enemy's movements and looking for ways to find the enemy is also the responsibility of a military academy student like Lu An as an intelligence staff officer in the future.

It seems that there is indeed a class dedicated to this......——,

Lu An suddenly became embarrassed, he smiled at Su Ruyu, scratched his head and said, "Why don't we try to find it?" Ha, cough, hehe! ”

"How do you find it? You just seemed to have a sudden realization, did you think of something? ”

Lu An pointed to the seven coordinate points displayed on the screen and said: "Actually, to find the possibility of the appearance of the enemy like this, our school comprehensively considers various factors, evenly divides the combat area, calculates the probability of the appearance of each area, and then determines the area where the enemy may appear in turn according to the previous statistical distribution curve......"

"And then?"

"Well, we don't have to be so complicated, the simplest and most effective way is to draw a circle around the center of the circle around these coordinate points, and we can draw seven circles with a common overlap in the shortest diameter, and then that overlapping area is the last place where the target may be found."

Su Ruyu nodded thoughtfully and said, "Well, according to the method you said, we can actually do this when there are three coordinate points." ”

"Hehe, wasn't it uncertain if there was a spaceship at that time! In addition, the overlapping areas determined by the circle of seven coordinate points can be more accurate. ”

Soon, according to the method Lu An said, the seven discretely distributed coordinates circled an overlapping area on asteroid 273.

"This is it, isn't it?" Su Ruyu said suspiciously.

"Well, maybe, we'll see. Here, hmm, where is it? ”

Su Ruyu replied: "From here, go to the landing place we had before, cross about five kilometers, and then turn right seventy degrees and walk about three kilometers, which is a range of three hundred meters in diameter. ”

"Whew, okay, why don't we get a little ready, and then we'll go over and have a look?"

Su Ruyu took a deep breath and said: "It's not a little preparation, but a good preparation, ——, that area, unfortunately, it seems to be a crater area, in case we need to go down to the bottom of the valley with unknown depth, it will be really troublesome......"
