The two sides continued to approach, and the atmosphere of the fleet became more and more solemn, and gradually tense to the extreme.

"Strong electromagnetic interference! Radio failure! The nervous communications staff officer spoke quickly, as if this was the only way to make himself less nervous.

"Activate the resonance communication device—" Lu Jian was expressionless.

"Unidentified aerial vehicles slow down! Fifty-four light-seconds away...... The speed keeps dropping! The news was like a tranquilizer, and the atmosphere in the command suddenly calmed down.

The distance of more than 50 light seconds is far beyond the range of conventional strikes, and no weapon in the expeditionary force can achieve the purpose of rapid attack at such a long distance, except for light-speed torpedoes. The possibility of the enemy attacking at this distance is also very small, and slowing down means operating a safe distance, and from this point of view, the opponent should not be hostile.

"Keep your speed at a distance, and be ready to go faster-than-light at any time!" Lu Jian cautiously ordered, "Give me a magnified image of the other party." ”

Whoever has speed has the advantage in air combat, so never leave a battleship stationary unless absolutely safe.

The distance of less than fifty seconds is no pressure on the optical system, and soon more than a dozen asteroids of different shapes appeared on the big screen, and Lu Jian, who saw this scene, couldn't help but be stunned, and a sense of familiarity suddenly appeared in his heart.

Ye Fei, who also saw this scene, suddenly recalled the experience in the Battle of the Bone Mound, and immediately sent the highest-level communication request to the flagship, and after the application was approved, Ye Fei couldn't wait to say: "Commander, it's a mechanical civilization!" ”

Lu Jian was stunned, and then remembered the battle report of that year. The asteroid-like appearance and strong electromagnetic interference are completely in line with the appearance characteristics of mechanical civilization!

"Report, Electromagnetic Interference Gone, Unknown Communication Request Received!"

Lu Jian completely put his mind at ease, sorted out his military appearance and said, "Take it in." ”

A magnetic baritone echoed through the command: "Hello, human, I'm the main number six. ”

"Hello, allies." Lu Jian's tone was neither humble nor arrogant, "I am the commander of the First Fleet of the Chinese Expeditionary Force. Lv Jian. ”

Humanity has long been an offensive and defensive alliance with the Vanguard Four, which represents the mechanical civilization. It's best to call each other allies.

"Oh, that's a long name." The main force said with emotion, "My clan has not mentioned your arrival, can I ask you what you mean?" ”

Lu Jian's cheeks twitched. Resist the urge to explain that his name is not long: "It's simple. Humans are not the same as intelligent machines. We need the right environment to survive, there are planets with the right conditions, and we want to migrate to the planets here...... How? Is there a problem? ”

The adaptability of mechanical civilizations is thousands of times stronger than that of the Outer Skeleton Man. There is no need for a habitable environment at all, so there is no fundamental conflict of interest between humans and mechanical civilizations, which is the main prerequisite for human beings to ally with mechanical civilizations.

"We have no intention of interfering with the immigration of our allies, but not here." The main force six said unhurriedly.

"For what?" Lu Jian was slightly angry in his heart, "If I'm not mistaken, in the agreement of the alliance, not only should you not stop, but you should also conduct interstellar migration by humans. ”

"Don't overload, my friend, your processor is rising." The main force six is still not in a hurry, "I didn't mean to stop you, I know that you want to occupy the fourth planet here, but I'm sorry, the Outer Bone Race arrived here before you, and they have already occupied that planet." ”

The main six do not know about humans as well as the Pioneer Four, but the human anger is very similar to the processor overload of a mechanical civilization.

"What?" Lu Jian was shocked, "They've already arrived here?" ”

Lu Jian was the only one in the whole fleet who knew that this time the task of seizing was not as simple as it seemed on the surface, and it was not only the Americans.

Things have to start a few years ago, when the Pioneer Four met with the countries of Earth at the same time, and when they finalized the alliance between the two sides, in addition to mentioning the Wolf community and the Sky Wolf community, they also mentioned the Outer Bone Great Race that was about to arrive in Grilitzer 581.

The so-called Outer Bone Great Clan is actually the strongest group of all Outer Bone People.

Theoretically, mechanical civilization has infinite life, so the concept of time is very dull, and the so-called imminent arrival may be a few days later, maybe a few years or even more than ten years.

Before the U.S. Expeditionary Force was formed, it had a detailed communication with Vanguard 4 and confirmed that it would take a few years for the Outer Bone Race to arrive at Gliese 581, and then the plan for a direct flight was set - to occupy Gliese 581 before the arrival of the Outer Bone Man would be equivalent to the sovereignty of the United States over the planet, even if the planet was taken away by the Outer Bone People soon after, the colony star that the Americans had announced to occupy would no longer become Borderland.

The reason why the Chinese side put forward the preemptive plan is also based on the same calculation.

However, the details of the meeting that year were not publicly circulated, although the headquarters of the Heavenly Army provided Lu Jian with detailed mission information, but the level of confidentiality of the information was extremely high, and in the entire First Fleet, he was the only one who knew that the skeleton people outside the Dao were approaching.

It's a pity that Ji Lu's drawing is not as fast as the change, back then, the Pioneer Four had mentioned that the main force of the mechanical civilization had been following the outer bone people, and when it was confirmed that the UFO was the mechanical civilization just now, Lu Jian realized that the situation was not good, but he still had a glimmer of hope in his heart, but he didn't expect that before a few words were finished, reality completely knocked down the illusion.

"Not yet, to be exact, but there's not much time left." So said the main six.

Lu Jian's eyes lit up: "How long do we have left?" "He has long lost faith in the concept of time in mechanical civilization, maybe there is still a chance!

The main force six replied without hesitation: "The Outer Bone People have entered this galaxy, and in four hours, they will be able to reach the fourth planet." ”

"Four hours?" Lu Jian was in great pain, the time was too short, it was not enough to board the planet and announce the occupation, how good would it be if there were not so many deviations on the road?

On the big screen, the clever Xu Dong has captured the Gliese 581g through the optical system, which is the planet in this asteroid system that is likely to have a habitable environment. Due to the angle problem, the optical system can only capture the side and back of the planet, most of the planets are hidden in the dark, only a dark blue crescent moon jumps on the screen, and the white clouds are like a veil that makes the surface of the planet difficult to distinguish, and can only capture a scale and a half claw on the surface of the planet in the gap between the clouds.

What a beautiful planet!

Lu Jian sighed in his heart.

"My friend, although the main force of the Intelligent Machinery has been tracking down the Outer Bone Clan, we are no match for them, even with you, so. It's better not to take risks. The main force six persuaded bitterly.

Lu Jian frowned. My mind is constantly calculating like a pot.

According to the Moscow Agreement, the standard procedure for occupying a planet is to go to the planet's surface and obtain detailed data about the planet. In particular, environmental data.

The main tasks are to record a video after landing on the surface of the planet, collect specimens of soil and various common organisms, scan the terrain of the entire planet, and analyze the composition of the atmosphere. Finally, all the data will be released to all mankind. and a new name for the immigrant star...... Environmental scanning and analysis of atmospheric composition can be done over long distances, and naming can only be done after all the work has been done, mainly the first two items.

Four hours is a little shorter. Nor can it be said that there is no chance at all...... If they fail to land on the planet first, when the Americans arrive, the planet will become a disputed territory, and unless China and the United States tear their faces, they can only give up the monopoly of the immigrant star and share it with the Americans.

When transforming Mars, the Americans once played this hand with the Russians, turning Mars, which should have been exclusively occupied by China, into a joint management of three companies, how could Lu Jian let history repeat itself?

He had no choice at all, and instantly made up his mind: "Order the Yangtze River to immediately fly to the fourth planet at full speed, land on the planet as fast as possible, record the landing video, and collect biological specimens." All work must be done within four hours...... No, in three and a half hours. ”

Now when he thinks of landing, Lu Jian will be the first to think of Ye Fei, and subconsciously ignore Bi Qun.

"Yes!" Ye Fei received the order and immediately commanded the Yangtze River to set off, and the spaceship disappeared in the colorful light and flew towards the fourth planet at the highest speed.

With just over 20 astronomical units, it only takes five minutes for the Yangtze River to reach its target at full speed.

"Oh, my friend, what are you going to do?" The main force six found that the Yangtze River had disappeared, and although he was very preventive, the covenant stipulated that the two sides could not interfere with each other's actions, and he could not violate the constraints of the covenant.

Relatively speaking, humans are too flexible to break their covenants at all.

"Nothing." Lu Jian's eyes were blazing, "Isn't there still four hours left?" ”

As soon as the video of the capture of Gliese 581 is released, all mankind will immediately realize that the speed of the warships of the Chinese Expeditionary Force is much higher than the theoretical speed of light of 9.2 times, and there is no need to care about the mechanical civilization to know the inside story.

The main force six was helpless: "I hope you are right, I hope you are right." ”

"Rest assured, my friend, I will not put my fellow citizens at unnecessary risks." Lu Jian swore and said.

"Report!"

"Speak!"

"Look, Commander!" Xu Dong's fingertips jumped rapidly, and the picture on the big screen changed, turning to another planet, "This is the fifth planet!" ”

Xu Dong's voice trembled violently with excitement, just like a ten-year-old bachelor who married a young and beautiful wife, and finally came to the moment of entering the cave room.

Lu Jian took a closer look and immediately held his breath.

On the big screen, there is a planet with a white tone, most of the planet's surface is covered with white, but near the equator, it is full of life, and a large green land and green ocean are scattered.

Compared to Planet 4, which has not yet lifted the veil, the green color on the surface of Planet 5 is clearly a protist of this planet!

A galaxy has two planets with liquid water, one of which has a biosphere, and the sky really favors this little red dwarf.

"The Yellow River will set off immediately and land on the fifth planet!" Lu Jian didn't want to give an order, "The mission is the same as the Yangtze River, hurry up!" ”

"I must warn you, my friend." The main force six, who had not been cut off from communications, heard all the orders, "The fifth line is farther away, and the arrival of the enemy is less than four hours. ”

"Thank you very much, we will definitely evacuate before the Outer Bone Man arrives."

"Good luck to you. My friend. After the main six finished speaking, he cut off the communication.

"The Yangtze River reports that our ship has arrived in the outer space of the target planet and is preparing for orbital airborne!" Ye Fei's voice suddenly attracted all of Lu Jian's attention: "What did you say?" Airborne? ”

"Yes!" Ye Fei replied, "This is the fastest way to land, wait for the landing craft to set off immediately." ”

Time is pressing, and the orbital airborne can buy about three minutes.

Lu Jian hesitated for half a second and agreed to the request to be airborne.

The Yangtze River immediately opened a row of projection tubes in the belly of the airborne capsule, and a row of airborne capsules flew into the atmosphere of the fourth planet one after another.

Immediately after that, a landing craft broke away from the battleship.

At the same time, the Yangtze River began to scan the planet's terrain.

The Yangtze River, which highlights ground attack, also tends to ground attack with shipboard equipment. Scanning the terrain on the planet's surface is trivial. Not only the ground and the sea, but also cavities and mineral deposits at a certain depth under the stratum cannot escape the search of ground penetrating radar.

"Commander, the fourth planet is about 16,500 kilometers in diameter, which is 1.3 times the size of the Earth. It belongs to terrestrial planets. Water systems account for 47 percent of the total area. Liquid water and biosphere! Ye Fei sent the scan results back to the flagship as soon as possible, but then he became depressed again, "It's a pity." The planet has been tidally locked, although the atmospheric convection balances the temperature, but the temperature on the front is still about 60 degrees, and the temperature on the back side of the planet is about minus 30 degrees on average, only the temperature at the junction of morning and dusk is suitable, and most of the protists here are concentrated at the junction of morning and dusk. ”

Gliese 581 is a star much smaller than the Sun, and several planets are much closer to the stars than the larger planets of the solar system, and the distance between the fourth planet and the star is less than half the distance between Mercury and the Sun.

The ocean on the front is cloudy above, while the back is perpetually windy and snowy. However, the ocean on the back side is hidden under a thick layer of ice and remains liquid.

Such a planet, even if it has a habitable environment, has a very limited area to be exploited, and the only advantage is that it has no axis of rotation and a very stable climate.

Although the astronomical world had long speculated that this planet was locked, confirming this could not make Lu Jian feel the slightest sense of accomplishment, and his heart instead swelled with a sense of loss: "Ye Fei, you don't have to worry so much, complete the task first, use the fastest speed, understand?" ”

It is possible to emigrate only if there is a livable environment, as for the usable area...... The diameter is 1.3 times that of the Earth, the surface area is about 1.6 times that of the Earth, and the area is half more than that of the Earth.

"Yes!"

"Go ahead." Such a chicken-ribbed planet made Lu Jian at this time feel like Cao Cao was possessed.

However, this was not the end of the story, and soon the Yellow River also sent back news of the fifth planet.

The planet's gravity is about twice that of the Earth, its axis of rotation is rarely perpendicular to the plane of the ecliptic, there are no four shows on the planet at all, more than 70% of the planet's area is frozen in ice, and it is currently impossible to judge the ratio of the area of the ocean to the land. Only the temperature of the part equivalent to the earth's tropics is stable at about minus 7 degrees all year round, the native plants are low and stout, and most of the animals are small and fast, which is very similar to the earth's cold region ecosphere.

After hearing this, Lu Jian's heart suddenly cooled in half.

Forget about one chicken rib, but I didn't expect that two are all chicken ribs, how can people be embarrassed?

Fortunately, the good news came later, Gliese 581d, that is, the fifth planet, has a low level of greenhouse gases in the atmosphere, and it is completely possible to modify the planetary environment by modifying the atmospheric composition.

Finally, there was good news, Lu Jian became excited again - twice the gravity is indeed a big trouble, but human beings have mastered the artificial gravity technique, although it is impossible to adjust the gravity of the entire planet, it is not difficult to change the local gravity, it is great to only change the gravity of the colony...... Another trouble is that the air pressure is a bit high, but fortunately, humans are only sensitive to low air pressure, and high air pressure is not a big problem.

The movement of the two warships was not unreasonable, but the protists had to have as many specimens as possible, so the delay was relatively long. The normal capture procedure is not only to catch alien creatures, but also to do a good job of epidemic prevention at the same time as catching them, in case of infection with alien microorganisms.

Moreover, the epidemic prevention work is carried out in both directions, not only to prevent alien microorganisms from infecting humans, but also to prevent terrestrial microorganisms from infecting alien organisms.

The possibility of incurable diseases caused by unknown alien microorganisms is as high as 90%!

But now that everything can't be taken care of, Lu Jian's only order is to rush time!

Time passed minute by minute, and just over three hours later, the main force six took the initiative to contact again, warning Lu Jian that the outer bone man had arrived ahead of schedule and that the human race must be evacuated immediately.

The helpless Lu Jian did not dare to take the risk and immediately gave the order to evacuate.

The landers immediately returned to the landing craft with their harvest and quickly flew away from the planet.

After returning to the battleship, the landing personnel were temporarily quarantined and strictly forbidden to take off their combat armor. The Yangtze River and the Yellow River immediately left the dangerous airspace, and a few minutes later, the two warships converged with the main force.

The supply ship Pengzehu had already prepared the quarantine area, and after thorough disinfection, the specimens captured by the two warships were stored separately, and then the contaminated areas of the two warships had to be fully disinfected.

Lu Jian's attention never took away from the two habitable planets, and seventeen minutes after the main force six warnings, the two bone mounds flew close to the fourth planet, and then a large number of biological spaceships poured out of the bone mounds and entered the planet.

Lu Jian was distressed like a thief in his own backyard.

It didn't take long for the fifth planet to usher in three more bone mounds, and the same airborne landing was staged again.

This time, Lu Jian was distressed by the front yard.

"Commander, shall we just watch?" Xu Dong asked unwillingly.

"What else else can I do?" Lu Jian stared blankly at the five bone mounds on the screen, "Our strength is not even a fraction of the enemy's, what can we use to rob the outer bone man?" ”

"Commander......" Xu Dong gritted his teeth, "We can't get it, and we can't leave it to the Outer Bone Man, otherwise it will be the enemy!" ”

The current enemy is far from being able to do so with the expeditionary force, and if the Outer Bone Man makes full use of the resources of these two planets, he doesn't know how much his strength will rise.

"Main Force Six, my friend, I'm going to destroy these two planets!" Lu Jian made up his mind, and the mood of gains and losses suddenly became clear.

"How?" The main six asked calmly, "You don't want these two planets anymore?" ”

The mechanical civilization only needs mineral stars, and the habitable environment is not attractive to them at all, but it is natural creatures that create the mechanical civilization, so the members of the mechanical civilization always subconsciously protect the habitable planets with biospheres, which will not be destroyed easily.

"Yes, but the Outer Bone Man can't give me a chance. When they leave, there will be nothing left of these two planets...... Rather than that, it's better to wipe them out on the planet, and it's a shame that I'm not going to immigrate here. Lu Jian pursed his lips tightly, and the fierce light in his eyes flickered.

Planets don't run away on long legs, as long as they have the right environment, even a global catastrophe will be completely defeated in the face of time.

"What do you want to do?" The main force six suddenly felt that his processor was a little hot.

Lu Jian's gaze fell on the huge group of small celestial bodies on the periphery of the planetary system, and a trace of determination flashed in his eyes. (To be continued......)
