400 meters from the entrance of the branch cave at the back of the dormitory courtyard is the 104 Temple, which is one of the transfer hubs of 151, which goes north to the No. 1 warehouse of the giant machine and south to the nuclear reactor. If you look down from the sky, the main structure of 151 is a huge H-shape with a span of 1.5 kilometers, the 104 temple is a vertical vertical on the left side of this H, and there is a 105 main cave parallel to it, which is the one on the right, and the two main caves are buried under the two parallel ridges of Nanshan, and two ventilation towers with a diameter of 5 meters and a height of 160 meters are erected on each ridge.

Two people commute on the 104 zipline.

Shang Lu didn't expect that there would be an aerial cableway in the cave, with slings hanging under the 30-meter-high dome of the 104 Temple, and tracks laid on the ground, characters were divided, people commuted in the air, and goods were hauled on the tracks.

The 104 temple is brightly lit, Chen Yu said that it is lit up 24 hours a day, and every post in 151 requires someone to be on duty 24 hours a day. Sitting in the carriage of the ropeway, Shang Lu had time to observe the surrounding environment, he once again marveled at the grandeur and liveliness of the tunnel project, looking down, the trailer on the railroad tracks coming and going in both directions was crawling slowly, making a "clang" sound, like a mountain of dark crates piled on the trailer, tightly tied with ties and seals, and also pasted with a crimson warning, Shang Lu suspected that they were some kind of flammable and explosive, so he slowly moved under his feet.

It's a platform, as lively as a dock, with cranes on the sidewalks on either side of the tracks, where people from other tunnels gather, except for the army-green short-sleeved and dark blue overalls, their voices are chaotic and noisy, Chongqing dialect mixed with Mandarin, Henanese, and even Cantonese.

Looking up, the incandescent light of the sun headlights overhead is so bright that people can't help but want to hide, and everyone feels like a little bug about to be scorched under such a strong light.

There are six seats in the ropeway carriage, but there are only two people, Chen Yu and Shang Lu.

"We're going in the direction of a tree, and there's an observatory over there." Chen Yu said, "In the past, a tree was a scenic spot, and there was a lookout on it, and you could see the night view of Chongqing from the lookout, but later we built a higher one on the hill next to it, with an altitude of seven or eight hundred meters, which is higher than the Spring Ridge, and you can see the direction of the tea plantation." ”

The ropeway carriage continued to go deeper into the tunnel, and soon the noisy voices around it gradually faded away, and Shang Lu looked ahead, and the tall tunnel could barely be seen to the end.

This gave him the illusion that gravity was moving forward, and that they were on the elevator leading to the underground.

"Where are the angels?"

"Yesterday it was still at Dashiba, and it has been there for almost a week."

Shang Lu was stunned for a moment, "Big Stone Dam? Dashiba in Jiangbei District? Isn't that in the city? ”

"Ah no, no, it's in Dashiba in Nanchuan District, close to the Shiqiaoba Reservoir, more than forty kilometers away from us." Chen Yu said, "There are six big stone dams in Chongqing. ”

"Is it getting closer?"

"Yes." Chen Yu nodded, "But the speed is very slow, and the speed of the angels is very slow." ”

The ropeway car stopped, and Chen Yu took Shanglu to swipe the card to the elevator, and he said that the elevator went straight to the top of the observation station.

The observatory has a large platform at an altitude of more than 700 meters above sea level at the top of the mountain, with a white marble floor, sealed with a circle of pale yellow glass like floor-to-ceiling windows, a row of heavy three-defense suits hanging in a large cabinet on the side, and a duty room in the center, arranged like a radar station, but there is no radar. At this time, no one went to the observation station, only the cadres on duty sat in the room facing a circle of computer monitors, and there were four telephones on the table, three black and one red, three small and one large.

The two got out of the elevator, and when they saw the sun again, it was already dark, and they went down the mountain, and Chen Yu said hello to the cadres on duty.

"Lilac!"

"Pendulum?" Sitting in the duty room was a female lieutenant with short black hair, who looked up at him, "It's rare that you can come here, what?" Duty is over? ”

"Today's work is done, and the chief of staff wants to keep us down for a meeting, but fortunately I ran fast." Chen Yu said, "I brought the little chief engineer over to see the angels...... Come on, Lilac, let me introduce to you, this is the 151 technical commissioner and chief engineer of the base supported by the Institute of Automation of the Chinese Academy of Sciences, Shang Lu. ”

The girl looked Shang Lu up and down, then got up and stretched out her hand through the small window of the duty room.

"Hello little chief engineer, I am Ding Xiang, a technician at the One Tree Observatory directly under the base."

Shang Lu shook hands with her.

"How's the angel doing?" Chen Yu asked.

"It's still moving slowly." Lilac replied, "Now its location is probably in the area of Taipingchang Town and Hongshengji Reservoir, the range is about a circle with a radius of one kilometer, you know we can't determine its precise location from a distance, and the accuracy of the Riemann probe is limited." ”

"What about the curvature of space?"

"At present, the detected part is an approximate unit sphere, the tidal force density is within the estimated range, and the area of the exact four-dimensional contact surface cannot be estimated for the time being." Lilac shook her head, "It's too far away, wait for it to come into visual distance." ”

"Can the contact area accommodate Red Lotus's fist?" Chen Yu said, "If we can put our fists in, there will be no angel who can't be killed." ”

"I don't think it's a big problem." Lilac smiled.

Shang Lu didn't care about the conversation that the two didn't understand, he turned around and walked to the floor-to-ceiling glass window of the observatory, looking out from here, looking in the direction of the tea plantation, the earth was lifeless under the bright starry sky, the town that was originally a gathering place for humans had long been emptied, and the empty buildings were located in the quiet night, without a sound.

All that was left was the dark red lights that flickered in the darkness, and from a distance, they were only a little the size of sesame seeds, like fireflies, laid out regularly on the earth, thousands of them, forming a square.

"That's the Riemann probe." Chen Yu stood behind Shang Lu, "It's our early warning system, it can detect the curvature of space that is imperceptible to the naked eye, and the distortion of space-time means that there are high-dimensional objects approaching." ”

"Angels?"

"Angels." Chen Yu nodded.

Shang Lu got close to the glass, he tried to keep his eyes open, but there were still undulating ridges in front of him blocking his view, these hills were the defensive barrier of Chongqing, and through the huge shadows of these black mountains, Shang Lu would inevitably have a little inexplicable sense of security.

What is there in the world that can destroy mountains?

It is a part of nature, majestic, heavy, and standing still for thousands of years.

There was a lone peak at the gap in the hills ahead, standing upright, like a tall building at night, and like a huge rock protruding from the ground, strange shape, Shang Lu noticed it, he wanted to see it more clearly, but the light was too dim.

"Angels are in that direction, Taipingchang Town." Chen Yu patted Shang Lu's shoulder, stretched out his hand and pointed forward, crossing the ridge and ravine, "Lilac, what is the change cycle of that thing?" ”

Lilac sat in the duty room and turned her head to look at the computer screen.

"Three minutes to go."

With that, she pulled down the lanyard on the wall.

The alarm on the ceiling of the observatory went off, and a blinding red light swirled around the room.

"It's too noisy, Lilac, can you turn it off?" Chen Yu covered his ears with one hand, and pointed to the alarm with the other, "It's just us here." ”

"I'm going to have to pull it as it is." Lilac said, "Even if there's no one here, I'll have to pull it." ”

"What does the alert mean?" Shang Lu asked.

"Means you'll be able to see it right away." Chen Yu said, "One minute countdown. ”

"Thirty seconds."

"Ten seconds."

"You don't have to be so focused, you don't need to hold your breath, angels are not lightning, they don't slip away from you all at once, they often make a lot of noise." Chen Yu leaned against the railing of the observation platform, "As long as you are not blind, it is difficult for you to ...... if you want to see it."

Shang Lu's face suddenly turned red and turned red.

In his pupils, Chen Yu saw an extremely bright line.

No one knows why there is such a bright crimson pillar in the air, its source is far, far away, far away on the other side of the mountain, and it shoots diagonally upwards into the night sky, illuminating almost the whole world at once, as if there is a searchlight as huge as a star in the distance. Chen Yu turned his head suddenly, he saw that the huge searchlight began to turn, it swept from the sky to the ground, and swept down and swept through the Eight Desolations and Liuhe with an almost wielding long knife, everything in its reach was instantly evaporated, and the mountains, forests and wilderness were burst into flames!

In an instant, the world turned red.

"This is the angel." Chen Yu said, "We generally name it based on its sighting characteristics, and the name of this angel is Lighthouse Angel. ”

Shang Lu breathed heavily, and only then did he realize his arrogance, the enemy 151 was about to face was such a terrible monster, and he actually had a chance in his heart.

A fire ignited in the distance lit up the night sky, and at a glance, Shang Lu saw the lone peak he had noticed before, the rock-like shadow stood in place, standing between the hills, and the firelight illuminated one of its sides, it was a crimson giant, with broad shoulders and chest, and four long arms, it faced the direction of the angel and the flames, standing still.

Is that a red lotus?

Shang Lu thought to himself.

Is the young girl manipulating it? What was she thinking at this point?
