Countless comets and interstellar matter in the Oort cloud collide with each other like crazy.

The Oort cloud, which is as calm as the surface of the lake, seems to be ushering in a heavy rain, and the water waves on the lake surface splash and collide with each other.

A meteorite hits an asteroid, and the asteroid changes its trajectory and hits another larger asteroid. Countless meteorites and asteroids have been bouncing back and forth like ping pong balls. And these countless non-trajectories, and the situation of turning around each other has also begun to affect the forward route of the earth.

At this time, it is meaningless to clear the meteorites and asteroids in orbit, because a larger asteroid will rush towards the earth in the next second, so what the earth can do at this time is to attack and crush any small asteroids that threaten the earth. Planets and meteorites.

Under the control of the fire control radar, the defense circle and fortress satellites in orbit around the earth will disclose countless asteroids rushing towards the earth.

Countless lasers are launched every second, and the whole earth is like a hedgehog, attacking the asteroid rushing at 360 degrees without any dead ends.

"The No. 17 gravity generating device was hit by asteroid debris, and the internal electronic components were damaged and could not work properly. Please replace it immediately."

"Immediately calculate the route to the No. 17 gravity generating device and transport it from the space warehouse."

"The No. 11 energy battery of the No. 29 gravity generator is exhausted, please replace the energy battery immediately."

"Activate the internal backup energy source of the gravity mode device, and replace it immediately."

"No. 779, if the muzzle of the satellite's main gun is deformed..."

In the command hall of the Earth Federation Army, countless reminders sounded. All the staff are working in four shifts 24 hours a day, even so many people can hardly hold on. This is because the automatic processing mechanism of the starry sky is helping the staff, otherwise the gravitational generating device in the space is estimated to have been abolished three months ago.

The item stem is in the middle of the command hall.

Looking at the busy staff, looking at the big screen, frowning tightly.

"Xingkong, how much energy reserves do we have?" Xiang Gan asked in a low voice.

"Less than twenty percent."

"Can the mining on the moon keep up?"

"Mining is no problem, but the problem is that the transportation can't keep up. When each transport spaceship transports materials, it will affect the attack efficiency. If too many transport spaceships are dispatched at the same time, the asteroid wreckage will break through the defense circle, and the defense circle will be damaged. The equipment inside caused more damage."

"What about supplementing energy with wireless energy transmission?"

"The loss is too great, and the replenishment cannot keep up with the consumption."

"...Send battleships to make up for the firepower gap caused by the transport spacecraft operation. Fully exploit the lunar materials."

"Okay, boss."

Xiang Gan rubbed the space between his brows, and now he knows why there was a saying before that war is about logistics.

Now the earth is facing indiscriminate bombardment by countless asteroids, meteorites, and comets. It lasted for more than four months. The earth has not been attacked at all. It can be said that there is no asteroid wreckage that can break through the defense circle around the earth, let alone break through the atmosphere and fall to the surface.

But under this brilliant record, the consumption of resources can be said to be astronomical. These four months of fighting have consumed a full 60% of the earth's material reserves, of which energy consumption has reached 80%, which is about to bottom out.

Originally, Xiang Gan wanted to equip all the fortress satellites with electromagnetic shields, so that those asteroids with a size of more than ten centimeters did not need to be considered. But after Starry Sky calculated the energy needed to do so. Xiang Gan stopped talking.

Because that is simply unrealistic, and energy consumption simply cannot keep up. Think about if all the fortress satellites with a size of more than 160,000 800 meters are equipped with electromagnetic shields. Then it is turned on 24 hours a day, and it will take nearly 7 months to turn it on, so how much energy is needed.

The final result of the calculation is that unless the moon is hollowed out, the earth will not have so much energy at all.

There are now nearly 250,000 firepower points in the outer space of the earth, and the attacks for more than four months have almost exhausted the earth's energy reserves. If we don't step up the exploitation of energy, within two months, the firepower in outer space will be misfired, and the earth will be smashed into briquettes by then.

But the current situation is not too bad, only the logistics supply of the earth can keep up, and it is no problem to persist until reaching the hall of civilized race. According to the current speed, there are still 82 days to reach the palace of civilized race. As long as there is no problem with the gravitational force generating device, it is enough to keep the earth at this speed.

"A 17-kilometer-diameter asteroid 37 million kilometers away was hit to change the rules. Its goal is exactly the route of the earth, and it needs to be destroyed immediately."

"Scan the internal structure of the asteroid, determine the location of the attack, launch..."

"Immediately launch ten nuclear bombs with the equivalent of 1 billion tons of TNT." Xiang Gan said immediately after hearing the conversation of the operator below.

"clear."

In an instant, ten super-large nuclear bombs were launched. These nuclear bombs shuttled like fish among countless meteorites and asteroids, avoiding these meteorites. But even so, four nuclear bombs were hit by asteroid wreckage over a dozen centimeters in size while advancing, and they had to stop halfway.

Fortunately, these nuclear warheads are specially manufactured, even if they are hit by asteroid debris, they will not detonate. They will only detonate after receiving orders.

In line with the principle of waste utilization, Starry Sky will detonate these nuclear warheads immediately after the other nuclear warheads are farther away.

In an instant, light comparable to the light of stars erupted in the orbit in front of the earth. The power of a nuclear warhead with an equivalent of more than 1 billion tons of TNT erupted was terrifying. In an instant, small meteorites and asteroids within hundreds of thousands of kilometers around them were all hit by nuclear bombs. The impact of the explosion was thrown out by the shock wave.

When the light disappeared, the route in front of the earth suddenly became much cleaner, at least within hundreds of thousands of kilometers.

Eight hours later, the giant asteroid was detonated, and the debris was ejected in pieces.

The giant asteroid was blown up, and Xiang Gan also breathed a sigh of relief. He is not afraid of other things, like those large meteorites hundreds of kilometers or asteroids several kilometers in size, there are not many threats to the earth. Because such asteroids are just a matter of one or two shots for fortress satellites, and they can definitely explode before they enter the defensive circle.

But this kind of asteroid with tens of kilometers and tens of kilometers cannot be solved by the fortress satellite. If these giant asteroids are allowed to enter within 1 million kilometers of the earth, they will definitely cause great damage to the earth's defense circle, and they may even crash into the atmosphere.

One month later, the earth's material reserves dropped to the 20% dangerous warning line, and the energy reserves were still 15%. At this time, it was 51 days away from the palace of civilized race.

Two months later, only 13% of the earth's material reserves and 7.2% of its energy reserves remain. At this time, there are still 21 days away from the palace of civilized race.

After two months and 20 days, the material reserve of the earth is only 5.3%, and the energy reserve is 0.7%. At this time, it is still 19 hours before the hall of civilized race.

"Xingkong, how many satellites are left in the fortress?" Xiang Gan said weakly with dark circles under his eyes. He hadn't slept for 39 hours.

"There are still 135,200 left, and now these fortress satellites have all been mobilized around the gravity generator to ensure that there is no problem with the gravity generator."

"Can the energy of these fortress satellites last for 23 hours?"

"Thirty-seven percent is fine, and the energy of the remaining fortress satellites will be consumed within 23 hours."

"Give up attacking meteorites below one meter and let them hit the atmosphere. The earth orbit defense circle attacks those meteorites that threaten them or the orbit can rush into the earth. When the number of fortress satellites is less than 50%, send All the battleships are on defense." Xiang Gan thought for a moment, then said to the starry sky.

"Okay, boss."

Xiang Gan glanced at the big screen again, thinking that as long as there are no problems with this arrangement, it should be able to last for 23 hours.

Ten minutes later, Xiang Gan leaned back on the chair and fell asleep. He couldn't hold on any longer.

After sleeping for 11 hours, when he woke up, he found himself in the rest room of the office.

"Xingkong, how long have I been asleep?"

"Boss, you slept for 11 hours and 17 minutes."

After hearing this, Xiang Gan got up immediately. Although he washed his face with cold water to wake himself up, he ran back to the command hall.

"Xing Kong, how much energy reserve is left now?" Xiang Gan asked hurriedly.

"There's a half-a-half percent left."

"Don't use these energy reserves anymore. At the same time, adjust the power of the gravity generating device to the maximum, and start overloading without fear of loss. Call out all warships to help defend." Xiang Gan said hastily after listening.

"Okay, boss."

Only then did Xiang Gan have time to look at the big screen, but what made him more concerned was that the operators below seemed to have expressions of despair on their faces.

"Cheer up, there are still the last few hours, you must persevere." Xiang Gan said loudly to the following.

After listening to Xiang Gan's words, many people had strange expressions on their faces. Finally, a young man bit his head and said, "Chairman Xiang, I'm not questioning you, but there is no way out at all. Now our position We are still in the middle of the Oort cloud, and it will take more than two years to leave the Oort cloud. But now let alone two years, we can’t even hold on for two days, are we..."

"What nonsense are you talking about? Who even told you to leave the Oort cloud to avoid this crisis. Now there is a natural refuge more than 60 million kilometers in front of the earth, and we will be safe there. Xiang Gan said loudly.
