Annihilation of the solar system

The moon's twilight line slowly swept across the spire of the more than 300-meter-high laser tower, and darkness covered the laser tower and the moon like a cloak. Compared to the earth, the moon's twilight line moves very slowly.

Because of the Earth's tidal locking, the Moon's rotation period is the same as its revolution period, which is as long as one month.

However, since the surface of the moon is close to a vacuum, there is no scattering effect on light. This means that there is actually no real meaning of morning and dusk on the moon. The dawn and dusk line is a clear dividing line between light and darkness. One side of the line is close to minus 180 degrees Celsius.

The other side is pitch black, while the other side is as bright as 127 degrees Celsius.

Such a temperature difference spanning 300 degrees Celsius makes the thermal expansion and contraction effects of any construction material very obvious. Especially for a laser transmitting tower that is 300 meters high and will vibrate with small amplitude and high frequency during operation. After crossing the dusk line, the tower

The inspection of foundation settlement marks, displacement marks and verticality marks becomes particularly important.

The outline of the laser tower under the dark night glowed with a long red light. This was the aircraft's anti-collision warning light. As the light lit up and dimmed like breathing, the laser tower was like a sword thrust into the deep space, spreading and rising.

of murderous intent.

On the horizon that is almost mixed with darkness, there are two small red light spikes. Those are the other two transmitting towers outside the horizon. They are arranged in an equilateral triangle and together form a laser transmitting array. Counting the back and the North and South Pole

, there are a total of four laser emission arrays on the lunar surface.

Under the tower, a dozen people were gathering under the light of the lunar rover. They were a team of marking inspection engineers led by Li Linjie. Under this magnificent tower, their tiny figures were like a handful of ants under the Monument to the People's Heroes.

.

"Mr. Li, the markings on the last tower of the entire laser array have been reviewed, and all markings are in good position," an engineer said to Li Linjie.

"Let's go back to the monitoring station first!" Li Linjie replied.

Subsequently, the three lunar rovers drove to the monitoring station in the center of the three laser transmitting towers. It was a hemispherical sealed building. Most of the three laser transmitting towers can be seen in the glass dome on the second floor.

.

"Hey! Did you notice that the colorful clouds that appeared on the spore clusters and the broken ice belt have disappeared?" An engineer said, pointing to the stretching light belt in the space.

"Yeah, it was so big before, like a nebula. It partially covered the spore clusters and the broken ice belt. There must be something wrong with the space turret." Another engineer said.

"When I was checking the No. 3 foundation settlement mark, I felt a bright light appear in the colorful cloud, like something exploded..."

Li Linjie was about to stop them from continuing to discuss this topic that would make the atmosphere tense. Suddenly, an alarm message popped up on the computer on his arm, and almost the same alarm message popped up on the computer on everyone's arm. Li Linjie clicked on the message:

"Attention to all units! The laser defense system has begun to warm up, please be prepared before launching!"

"That's not right! According to the plan, shouldn't we start pre-launch preparations tomorrow? Why has it started now?" A young engineer asked in confusion.

"The laser emission system is under the command of the EDA Military Commission. We are just working together. Don't ask too much, just obey the order." Li Linjie said, although he also had the intention of stopping the young engineer's random speculation, but there was also a rise in his heart.

Questioned.

In the transparent dark starry sky, the mixed torrent of spore groups and broken ice belts that became clear again seemed to indeed indicate that there was a problem with the interception of the space turret, and the order for advance deployment just received further confirmed this speculation.

He looked at the gray torrent that could already be seen in the starry sky and was very confused. Not only was he worried about the first phase of the defensive battle, but also because his best friend Ke Guohao served on one of the space turrets. Three

The laser transmitting tower began to light up with blue apertures, which was a sign that the superconducting capacitor began to charge.

"Hey, I said that the high-energy lasers emitted by the three laser towers must be aimed at targets more than one million kilometers away at the same time. The requirements for the aiming coordination system must be very high!" The young engineer looked at the blue light that had lit up all over his body.

Laser tower, eyes flashing with excitement.

Li Linjie glanced at him:

"Didn't you work at Guanghan Palace Base before?"

The young engineer looked around at the three laser towers that surrounded them with only half of the towers exposed and said:

"Well, I have been working on the star port "Eden" before. Three months ago, the star port had to evacuate from low-Earth orbit to Lagrange point 12 to avoid possible low-Earth orbit impacts.

I originally wanted to stay on duty at the star port, but my major was in the assembly of large components, which was not suitable for me. So I couldn't stay, but I didn't want to go back to the ground. So I applied for the lunar base, but I didn't expect that the application would be returned.

Approved."

There was still a relaxed smile on his face under the visor of his aerospace helmet. Another engineer snorted coldly:

"Hmph! What, do you think you have a better chance of surviving in space or on the moon?"

The young engineer shook his head slightly. He didn't seem to be affected by these ironic words. He still had a faint smile on his face and searched the deep sky with his eyes:

"That's not true. When the crisis era came, I was 18 years old and had just been admitted to the flight academy. A year later, I went to space to participate in the space station construction plan. The day I received the notice that the star port was to move its orbit happened to be my 30th birthday.

I just thought, I have been in space for half my life, and I don’t want to go back to the ground. While I still have time, I want to see more of this beautiful starry sky and see more of the world that I have never seen before.

Now that I have come to the moon, I have no regrets."

The young engineer's words were very relaxed, but everyone could hear the faint sadness between the lines. A young man in his prime faced his upcoming fate so calmly. Everyone under the dome of the monitoring center admired him.

At the same time, I also felt the ruthlessness of the wheel of fortune.

"The emission angles of these three laser towers are fixed. The laser beams will be emitted to the space station with large prisms in a geostationary orbit at an altitude of several thousand kilometers. The prisms will converge the three laser beams into a higher energy laser beam, and the refraction system of the prism will

Shoot the high-energy laser to the target location." Li Linjie's voice broke the silent atmosphere.

"Wonderful! With four sets of laser systems distributed on the front and back sides of the moon and at the north and south poles, we can ensure that at least two sets are functioning at any time!" the young engineer said excitedly.

"Yes, the last big ice block was too small and hid on the back of the earth. Let's see how they hide in these hundreds of thousands of kilometers of spore groups and broken ice belts!" another engineer said angrily.

"When I was at the star port, I heard from the staff of the lunar base in transit that the energy of the lunar laser is very high. I don't know how effective it is in dealing with spore groups and broken ice belts in space." The young engineer asked again.

Li Linjie smiled slightly:

"When I participated in the acceptance inspection, I also asked the weapons system engineers the same question. They said that if the target is changed to the North Pole of the Earth, a high-energy laser can cut the Arctic ice cap into small pieces like cheese."

At this moment, undulating waveforms and jumping data appeared on the console screen. Three bright red laser beams were ejected from the three tall tower spiers on the edge of the horizon, and converged on the prism thousands of kilometers above the top of the monitoring station.

superior.

A blood-red sun suddenly appeared in the originally empty space, and its scarlet light instantly illuminated the entire moon like a purgatory battlefield sprinkled with blood. Before the engineers inside the monitoring station could exclaim, they were filled with

The red light of the whole world suddenly stopped, and the world returned to gray and white.

"The high-energy laser system works in the form of pulses. After two seconds of irradiation, there will be a short charging interval, and then it will be emitted cyclically."

As soon as Li Linjie finished speaking, scarlet light filled the whole world again.
