The four assault landing ships quickly gathered their scattered personnel and evacuated the vicinity of the bone mound as quickly as possible, and when the four warships withdrew to a safe position, the Aquila silently fired a planetary burst bomb at the bone mound.

The huge missile drilled into the shaft that went straight to the core of the bone mound with unerring accuracy, and after more than ten seconds, the bone mound suddenly bloomed like an electrified lamp, and countless torrents of flames erupted from the shafts all over the surface of the bone mound, and then the blue-spotted bone mound shattered into several large pieces from the inside out, turning into several veritable asteroids.

Ye Fei, who returned to the bridge, watched the destruction of the bone mound without saying a word, and said with emotion: "Our battleship is compared with the enemy's bone mound, just like a bean next to a watermelon......

"It's a pity, this bean has already killed more than one watermelon, and there will definitely be more in the future." The veterinarian smiled and took over, "If only there were a few more beans like this." ”

"Needless to say!" Ye Fei let out a sigh, "It's finally over." ”

"yes, it's finally over." The veterinarian accompanied Ye Fei and watched the scene outside the ship together.

This was the second large-scale battle between humans and the Outer Bone Man in Gliese 581, from the evacuation of Gliese 581 by the Third Fleet to the destruction of the Blue Spotted Bone Mound by the Aquila, which lasted only more than half a month.

Compared with the first battle, the strength of the foreign bone side in the two battles is roughly the same, while the number of warships on the human side is much lower, but the combat effectiveness has increased more than a step - on the surface, the victory in the first battle is the result of the unity and cooperation between humans and mechanical civilization, but in fact there is no mechanical civilization. It is simply impossible for humanity to win the first battle.

The second battle was not supported by mechanical civilizations, and the Third Fleet and the American Starfleet stationed in Gliese 581 suffered heavy losses, and if it were not for the Aquila crossing to turn the tide, the outcome of the battle would have ended in the complete defeat of mankind.

But Ye Fei, who won the battle, couldn't be happy.

He was one of the first humans to arrive at Gliese 581, and he still remembers the scene when he first arrived in this planetary system, but now Gliese 581 has long since been disfigured beyond recognition by the great war between humans and the Skeletons.

The fifth planet, which originally had a primary ecology, became a lifeless death star due to the impact of the bone mound and the light-speed torpedo, and no trace of the original can be found; After the bone mound shattered, countless celestial bodies of all sizes were formed to cover the entire galaxy space, which was also mixed with an unknown number of biological battleship remains, human warship wreckage, and even the remains of human beings and exoskeletons floating in the helpless void.

All of this makes Gliese 581 look like a chaotic junkyard.

The veterinarian accompanied Ye Feifa for a while. Suddenly, he asked, "What next?" Is it withdrawn? He didn't say this on the fly.

The battle for Gliese 581 came to an end. There is no need for the Aquila to stay here anymore, and the location of Gliese 581 is twenty light-years away from the solar system, which is the farthest battlefield from the solar system in the human front, and the most advanced salient of the Allied defense line!

Salient in the battle line. It is usually a support point for your side. Thorns in the flesh of the enemy. But the position of Gliese 581 is too poor, and it is very suitable to describe it as lonely. Moreover, Gliese 581 is only a red dwarf, although it has many planets. However, the galaxy is too small, and there is no complete military base, so it does not have the conditions for fortressing, and it is impossible to support the fleet for long-term holding.

Tactics must serve strategy, no matter from which point of view, giving up the Gliese 581 is the right intention, after all, the overall strength of the human race is still a little difficult to deal with the outer skeletons, and it is more beneficial to the overall combat deployment to withdraw such a strong combat power of the Aquila into the overall defense line.

Ye Fei frowned tightly and didn't speak, and only said softly after a while: "I don't know what Lu Dao means, look at the meaning of the headquarters." After saying that, he returned to the command position and connected the communication of the headquarters of the Sky Army.

The command center received a communication from the Aquila, and the combat staff immediately forwarded the communication to the head of the shift.

"I'm Ke Long!" On duty today is the chief of staff of the Celestial Army, who has just been promoted from his deputy post.

"Chief of Staff, I'm Ye Fei, the captain of the Aquila!" Ye Fei reported to the door, then briefly introduced the current situation, and sent the detailed information related to the battle to the command center, and finally asked for the next action plan.

In fact, asking for instructions on the next action plan is Ye Fei's most important purpose.

Ke Long listened carefully to Ye Fei's report and asked calmly, "How is the situation of Yin Yang Star?" ”

"It's not very good, we haven't had time to clear the enemies on the Yin Yang Star, the number of enemies entrenched on the planet is unknown, but it is absolutely indispensable, if the enemy is cleared on the premise of protecting the ecological balance of the planet, it is impossible to regain control of the Yin Yang Star in a short time, and a new bone mound may appear at any time." Ye Fei did not hesitate to say his judgment, and vaguely reminded his suggestion.

Just kidding, if he had been ordered to take back control of the Yin-Yang Star, the Aquila wouldn't have to stick here?

Ke Long was silent for a moment and said, "Ye Fei, I understand the current situation of you and your fighters, but I must also remind you that Gliese 581 must be controlled in our hands. ”

"For what?" Ye Fei asked puzzled.

Gliese 581 is one of the few planets with independent ecology discovered by humans, and if there is no interference from the Outer Bone Man, it is not a problem for humans to transform the Yin and Yang Star, but in the Outer Bone Army, the new Outer Bone Population may re-enter this devastated planetary system at any time, and he does not see any need for this barren planetary system to hold on.

"Actually, the problem is not Gliese 581, but on Giant Star!" Colon said.

"What?" Ye Fei was stunned, "What's wrong with Giant Star?" ”

Ke Long didn't intend to hide it from Ye Fei, and immediately explained: "Presumably you also know that the Giant Star is the only real colonial star at present, do you understand what kind of significance the Giant Star has to our country and nation?" ”

"I don't really understand, but I probably do." Ye Fei told the truth, he would never pretend to understand in this situation.

"That's good." Colon said. "We started the migration in May last year, and in more than a year now, we have invested 1.47 million immigrants and a lot of manpower and material resources in Giant Star, where three large cities, seven medium-sized cities and countless small settlements have been initially built. In the future, the investment in immigration and manpower and material resources will only be more, and it is impossible to reduce it in the short term, and the initial investment is completed by the military's transport ships, but interstellar migration is a long-term process, and it is impossible for the military to undertake this task all the time, and it is imperative to introduce civilian forces. ”

Speaking of which. Ye Fei suddenly remembered Jiang Yufei. Didn't he say that he wanted to buy a faster-than-light transport ship to run interstellar routes?

He didn't understand what Ke Long was doing with these things, but he could think that Chief of Staff Ke must have his intentions, so he listened quietly.

Colon paused and said, "You are used to the speed and endurance of warships. It may not be clear what will happen to civilian faster-than-light ships. At present, civilian transport ships led by the military have been put on the market. But civilian ships cannot pursue extreme range and speed like warships, these ships must free up enough space to serve as cargo holds, and must find a balance between speed and energy costs. Therefore, the speed of these spaceships is not very fast, and the range cannot reach the distance of twenty-nine light years, according to the current level of technology, civilian spaceships must be resupplied twice on the way to Giant Star, at least twice! ”

Ye Fei suddenly realized: "You mean that Gliese 581 is one of the pre-selected supply points?" ”

"Yes, that's it." Colon said.

Interstellar immigration is definitely a thankless loss-making business, if it is not an act of the state, no matter how rich an individual or organization is, it is impossible to support the cost of interstellar immigration - the question is not how much interstellar immigration costs, but to find a new home for mankind, so that in the case of mortal threat or even complete destruction of the home planet Earth, it will not be extinct for mankind!

In the Age of Discovery, the driving force that supported the voyages of navigators was the countless wealth of the New World, but no matter how dangerous the Age of Discovery, ships always sailed on the sea, even if the ship capsized.

Interstellar space is a completely different concept, each planetary system is an island in the universe, and it is impossible for anyone to fly through the space of light years to the interior of a planetary system in a conventional way after a shipwreck.

The danger of flying to the universe has increased greatly, but the potential benefits are not much, exoplanets may have a large number of precious minerals, special native animals and plants, but these products can not be transported back to the earth, it is not a fart, and the degree of human development of the solar system is not high, the minerals contained in the outer solar system are still waiting for human development, no matter how precious and rare minerals are transported from exoplanets to the earth, the price will be an astronomical amount, and only idiots will do this kind of eroded trading.

No matter how you look at it, interstellar transportation is not a good business, and only migration at the strategic level in the form of a state can have the possibility of success.

Civilian ships are slow, take a long time, and have a much worse quality than warships, and if they don't replenish fuel and repair the hull on the way, it is impossible to fly as far as the Giants.

"Chief of Staff, do you say this because you want the Aquila to stay in Gliese 581? It's not that I'm too talkative, the Outer Bone Colony could appear at any time, and it's impossible to establish a permanent supply base in this place at the moment. "Ye Fei can fully imagine how much manpower and material resources the country has invested in the giant star, but building a colony star under the threat of the Outer Bone Man is not much different from sending him to death, and the gains outweigh the losses.

"You think badly, the civilian spaceship has not yet sailed to the Giant Star, and I have no intention of letting you stay there." Menglong explained, "The meaning of the headquarters is that as long as the planet is still there, even if it is robbed by the Outer Bone Man, we can take it back, but we can't let Yin Yang Star become an accomplice of the Outer Bone Man." ”

Ye Fei nodded heavily: "I understand, there are still some storm fungi on the Aquila. ”

"No, storm fungi are organic, and maybe give the exoskeletons some time and they will be able to digest the storm fungus too."

"What do you mean...... Destroy the Yin and Yang Star? Ye Feiden hesitated.

No matter how bad the conditions of the Yin and Yang Star are, it is a living planet after all, and if it is destroyed like this, it is too tyrannical, right?

"It's pretty much the same, but it's not the same thing." Ke Long actually admitted it publicly.

"Chief of Staff, if this planet is destroyed, how can we build a supply point?" Ye Fei has walked through a lot of galaxies, but the only ones that have suitable conditions for immigration are the Yin Yang Star and the Giant Star.

"I don't mean to wash the floor with a nuclear bomb." Colon said. "The military has organized top scholars in astronomy and ecology to discuss that the most important thing on an ecological planet like Yinyang Star is not the ecosystem, but the distance between the planet and the star!"

"Huh?" Ye Fei's mind didn't react for a while.

However, the veterinarian's reaction was very fast, and he immediately leaned over to Ye Fei's ear and whispered: "The chief of staff means that the distance between Yin Yang Star and Gliese 581 is just enough to maintain a suitable temperature on the surface of the planet. ”

Ye Fei immediately understood what the veterinarian meant: "Chief of Staff, do you mean to only destroy the ecosystem?" ”

Liquid water is a prerequisite for the production of life, and the temperature of the morning and dusk circle of the yin and yang stars is maintained at about 20 degrees for many years, and there is no shortage of water on the yin and yang stars, these two conditions are the preciousness of the yin and yang stars!

Even if all life on the Yin Yang Star is wiped out, as long as the planetary environment does not change. It won't take many years. New creatures are bound to spawn again.

In other words, as long as the Outer Bone Man who occupies the galaxy is driven out, humans can completely sow earth plants and reproduce earth animals. Re-establish the ecosystem of the Earth model.

Colon glanced at the veterinarian. Nodding with satisfaction: "That's not what I meant. Rather, it is the result of discussions in the Ministry of Defense. If the Giant Star cannot be defended like the Yin-Yang Star, the First Fleet will also destroy the Giant Star ecosystem according to this plan when it leaves. ”

"I understand the Chief of Staff." Ye Fei thought about it carefully and then smiled bitterly, "Chief of Staff." On the Aquila, there doesn't seem to be a weapon that can destroy the ecosystem without harming the planetary environment! ”

The weapons of mass destruction he could think of were nothing but nuclear bombs, and even if they were only bombarded with laser cannons, they would have an irreversible impact on the planet's ecological environment.

Ke Long suddenly smiled: "When did I say that you should carry out this mission?" ”

"So what are you telling me so much about?" Ye Fei asked in surprise.

"Telling you so much is to let you understand the importance of Gliese 581, don't blow it up with a hot head." Colon said, "Your mission is to immediately go to the Giant Star to join the First Fleet, and cooperate with the First Fleet to protect the Colony Star...... The first fleet has been connected with the Outer Bone Man two days ago, and the two sides are currently facing off, according to the reliable information provided by the mechanical civilization, at least one colony will arrive at the Giant Star in the next month, if the Aquila can't arrive in time, the consequences will be unimaginable, your task is very difficult! ”

"I thought I could go back, but I didn't expect to fly farther and farther." Ye Fei smiled bitterly, "Let's go, what about the Yin and Yang Star?" ”

"I've contacted the U.S. Starfleet, and they're going to send a fleet to destroy the Yin Yang Star."

"Americans?" Ye Fei was stunned.

"You don't know what to do, do you? The Yankee Starfleet's secret weapon has been revealed. Colon said.

Ye Fei pouted violently: "Is that useless neutron cannon?" ”

"The neutron cannon of the fart, the secret weapon of the Americans is the high-power X-ray laser cannon!" Ke Long's words debunked the mystery.

The Allied fleets stopped the exoskeleton colonies near a dozen stars near the solar system, and the fleets of China and the United States, China and Russia, and the United States and Russia cooperated with each other many times.

Ye Fei smiled dumbly, he never thought that the answer would be so simple.

X-rays are also a type of light, and there are no technical difficulties in laserization, but it is indeed the first initiative of the Americans to put X-ray laser weapons into practical use.

After explaining the task, Ke Long gave a few more words, and then passed the recent battle report to the Aquila before cutting off the communication.

After Ye Fei ordered Jiang Xue to adjust the course and fly directly to the Giant Galaxy, he returned to the captain's room and began to read the battle report.

In the months that the Aquila has been fighting in all directions, the warships of other forces have not been idle, regardless of the Chinese, American, and Russian fleets are all operating at full capacity, and even the three fleets that the European Union has just formed have officially left for the battlefield.

Although the performance of the US and Russian fleets is far inferior to that of the Chinese side, at least it is also an old fleet that has fought head-on with the Aliens, but the fleet just formed by the European Union is also unexpectedly strong, showing extremely strong combat effectiveness in several battles, which impresses the military observers of China, the United States and Russia.

However, the fleets of various countries, including China, also suffered a lot of losses in the crazy attack of the Outer Bone Man, and Ye Fei was not interested in the specific situation, so he directly crossed over and did not look at it.

At present, the battle line of mankind is stable in the range of about ten light years around the solar system, and the Allies have divided their respective war zones according to the existing positions of the fleets of various countries, but in fact, the control areas of each country are staggered, and there is no law at all, and the so-called war zone is a joke at all.

Overall, the situation is fairly stable.

In addition to the resistance of humans, the mechanical civilization has also eliminated some of the outer bone colonies during this time, but the human beings only learned these news from the intelligence of the mechanical civilization, and there have always been some people in the upper echelons of the Allied forces who doubt the authenticity of the information.

War reports make up only a portion of all the documents, but in addition to them are internal documents of the military, which contain nothing more than recent military movements.

Ye Fei thought that this time the document was the same as before, but he didn't expect to open it and find an investigation report on whether he was in favor of merging the army, navy and air force into the heavenly army!

Since the emergence of the Heavenly Army, the position of the army, navy, and air force has become more and more awkward, and the voices of all branches of the armed forces have never ceased.

However, the conservative wing of the military has always had a certain say, so the traditional division of the military has not changed.

However, after the appearance of the Outer Bone Man, this situation has changed fundamentally, only the Heavenly Army has the ability to fight against the Outer Bone Man, although the army, navy and air force continue to transfuse blood to the Heavenly Army, but all along, the traditional three major military branches have only had a direct confrontation with the Outer Bone Man in the Martian Campaign, but the results of the Martian Battle are unsatisfactory, and the most difficult thing is to rely on the Heavenly Army to reverse the overall situation.

Today, the proposal to merge the various branches of the armed forces has finally prevailed, and as the saying goes, the wheels of history are rolling forward, and all the old forces of conservatism will be crushed by the wheels.

Ye Fei happily wrote his concurring opinion on the investigation report. (To be continued......)

PS: Today's state is bad to home, collapse.
