"Xu Negative?"

Rose caught a glimpse of Xu Cheng standing in front of Qi Zhenxiu and Qi Lin, her eyes almost popped out, and she thought to herself, didn't you say that you wanted to keep it secret, why did you run out openly?

"Xu Negative?"

Another voice full of surprise sounded, and Qi Lin glanced back at He Weilan, a meaningful smile appeared on the corner of her mouth

"Oh mom, Brother Zhengdao!" Liu Chuang shouted in a big ballast accent.

Your uncle, give me a nickname again and beat you.

The most shocked belonged to Li Feifei, her eyes were full of disbelief, and she shouted with a worried and slightly embarrassed expression: "Mr. Xu." ”

Mom, I used to tempt him in black silk and OL suits.

The world is too small!

She has entered the special department, and she can still meet her former boss, it is so fateful, it is simply a bad fate!

Hearing the voices of the four people, Xu Ying's reactions were also different.

To Rose, nodding casually.

To He Weilan, he nodded kindly.

To Liu Chuang, he nodded coldly.

To Li Feifei, he nodded with a gentle smile, and said with a golden mouth: "Xiao Li, I haven't seen you for a long time, you are becoming more and more like a goddess, wearing this dark alloy armor is much better than black silk and hip skirts." ”

Li Feifei couldn't wait to pull out a sword and give him a sword, which pot was not opened, and he hated it to death.

Qi Lin's eyes went back and forth on Li Feifei, Rose, Liu Chuang, and Xu Cheng, and the sound of grinding teeth sounded a little more, good sister, good comrade-in-arms, hum!

"What's the situation?" He Weilan quietly moved to Qi Lin's side and asked in a low voice.

"We'll talk about it later."

"You guys?"

Qi Lin smiled and said, "Weilan, believe me, in fact, you like him more than me." ”

He Weilan was like a little wild cat whose tail had been stepped on, and shouted: "What kind of international joke are you making......

"Ahem." Dukao coughed lightly twice, and introduced to everyone: "His name is Xu Cheng, some of you know him, some of you don't, I say a code name and you will understand it all, Xu Cheng code name Pangu God." ”

"What?"

This time, even Qi Lin was a little shocked.

Xu Cheng, Pangu, Zombie True Ancestor, let's play with nesting dolls, the vests are one after another, endless, right?

Her instinct told her that this might not be the whole story of Xu Cheng's identity.

"Instructor Pangu."

Rose opened her mouth and shouted, and then saluted Ducao and the others on the projection: "Report to the leaders, except for Su Xiaoxi, Wu Jiyi, Zhao Xin, ......"

Dukao interrupted: "Okay, don't report it, we all know the situation, they won't be able to come back for a while, let's have a meeting first." ”

"Yes." Rose stepped aside.

Uncle Huang's gaze swept over Rose, Qi Lin, Ge Xiaolun, Liu Chuang and others one by one, and said with a pleased smile: "Male soldier company, one company can be worth one million male soldiers, I have seen your performance, very good, very good." This time, I suddenly called you back, my relatives can't be reunited, and I can't have a good Spring Festival, do you have resentment in your heart? ”

Ge Xiaolun and the others said in unison: "Always ready!" ”

"Good!" Uncle Huang praised and preached, "Can our satellites detect how many people have come to this gluttonous civilization?" ”

The technician in the video replied: "Report to the chief, the Denuo 3 detection and anti-detection satellite can only detect the flash signal of the suspected opening of the big insect bridge, and cannot detect the reality of the other party." ”

"Why?"

"Chief." "I think there are two possibilities, one is that they haven't invaded the solar system through the Big Worm Bridge. The second is that they have arrived, blocking the detection of Deno 3 by means that we cannot understand. ”

Uncle Huang nodded slightly, suddenly looked at Xu Cheng and said, "Knowing yourself and knowing your opponent will win all battles." Xu Ying, you have the ability to predict the future, and talk about the military strength of gluttonous civilization. ”

Xu Cheng replied: "I told Lao Du and them before that fate is reorganized, and the future is not accurate. In the original fate, the gluttonous civilization invaded the solar system in September, and now it is 7 months earlier. In the same way, the number of people they will come is also full of variables and cannot be accurately predicted. But as far as I know, the gluttonous civilization has a total population of about 1 million, and there is an astronautic-level vassal civilization, the giant wolf civilization, and at least 200 space warships are dispatched. ”

"200 ......"

There was a dead silence in the command hall, and even Liu Chuang, who didn't know much about aerospace-level civilization and had no concept of space battleships at all, was stunned, and the others had even more solemn faces.

After a moment of silence, Uncle Huang said to Rena: "Rena, our earth's technology is still a little behind, please help you Sun Civilization keep an eye on this gluttonous civilization and figure out their strength as soon as possible." ”

"Uncle Huang, I have already ordered Yuan Li."

"Thank you." Uncle Huang said gratefully, turned his gaze to Lian Feng, and asked with concern: "Lian Feng, during this time, you are responsible for forming the ground defense force and the space commando team, how is the progress?" ”

Lian Feng replied: "The progress is going well, the soldiers and equipment have arrived, and the training is proceeding normally. At present, we have built 20 Dawnlight A1 air and space fighters, 9 of which are deployed in orbit around the earth, and are on duty 24 hours a day. In terms of production capacity, an air-space fighter can be manufactured in an average of two days, and the production speed of other equipment is faster, and it is expected that the scheduled ground defense goals can be initially achieved in the next two months. ”

"You've reassured me." Uncle Huang laughed, and the laughter eased the solemn atmosphere in the command hall slightly, but soon, Uncle Huang restrained his smile and said solemnly: "Mercy Feng, how big is the gap between us and the space-grade civilization gluttony, and what are the odds of winning, you tell us in detail." ”

"Yes, Chief."

Lian Feng sorted out his thoughts and said, "As we all know, the cosmic civilization from low to high can be divided into primitive civilization, pre-nuclear civilization, aerospace civilization, god-making civilization, and super-god civilization. ”

God is a fucking well-known, and if it weren't for you aliens, the earthlings would know the five-point of civilization. When Xu Cheng heard the words 'well-known', he couldn't help but complain secretly.

If Lianfeng knew what he thought, he would definitely reply: "I didn't learn it from you." ”

"Our earth belongs to a pre-nuclear civilization, and the pre-nuclear civilization has some understanding of civilization and the universe, and has a variety of nuclear explosives of different powers, and has not yet gotten rid of the limitation of natural lifespan."

"Space-class civilization began with the development of its own aircraft that could break free from the gravitational pull of its home star and sail between stars. It is possible to establish a new survival system and production system outside the home star, and after nuclear baptism, we have a deeper understanding of life and the universe, and can use life science to extend the natural lifespan. ”

"There is a consensus in the universe that a mature, truly space-class civilization must master one iconic technology, and that is faster-than-light travel."

"To explore the universe, speed is important and crucial. Because the universe is so vast, the Milky Way galaxy where the Earth is located is more than 100,000 light-years in diameter, and it takes at least 100,000 years for light to fly out of the galaxy from one end. In a finite life, if you can't increase the speed of sailing, exploring the universe is a luxury. Even if the life span is extended, it is very short in the cosmic time scale. ”

"But at the same time, the speed of light is almost impossible to achieve, and the closer an object with a static mass is, the closer its mass and kinetic energy are to the speed of light, the mass and kinetic energy become infinite, and the energy and momentum required are also infinite. Secondly, the speed of light of an object will have a serious time dilation effect on the surrounding space-time. Based on these two points, almost all civilizations that have stepped into the threshold of space-level civilization will choose additional faster-than-light travel technology to reduce energy consumption and bypass the time dilation effect. ”

"That's the space jump, the curvature engine."

"Well-known ......"

Not again.

Liu Chuang, Ge Xiaolun, Qi Lin and others, who were dozing off and had straight eyes, let out a slight moan, and there was a feeling of being pressed to the ground and rubbed by someone.

As we all know, we don't know at all okay.

"Can you understand?" Qi Lin asked Xu Cheng in a low voice.

Xu Cheng replied casually: "It's very understandable!" ”

Yes, it's not a level of people!

Mercy Wind also seemed to realize that what he was saying was a bit annoying, and began to make a long story short: "Curvature navigation is a technique of navigating through compressed space-time, the principle of which is to create an artificial warp force field around a moving object using an antimatter-powered curvature engine, so that the object can move with this twisted curvature bubble at several times the speed of light. ”

"The energy consumption of curvature navigation is not related to the mass of the spacecraft, but to the size of the velocity bubble and the speed of the spacecraft. In addition, if the gravitational pull of massive celestial bodies is not addressed, curvature navigation cannot be used in the vicinity of massive celestial bodies, and forced use will damage curvature engines. ”

"And our solar system is rich in matter, there are nine planets, dwarf planets, asteroid belts and other celestial bodies, gluttonous civilization flew from Pluto to the earth, there are two possibilities in time, one is that they have solved the influence of celestial gravity, can use the curvature engine at will, that means they can reach the earth quickly, the specific time depends on their curvature navigation level. The second is that they have not solved it, and there is no wormhole to pass through, so they can only sail at sub-light speed. ”

"The ......"

Hearing a light cough, the wind omitted: "The Earth is 39.553 astronomical units away from Pluto, and at the speed of light, it takes almost 5.5 hours, and it will take even longer to travel at sub-light speed." That is, the war can take place in a few minutes at the earliest, and in a few hours. ”

"The above is an analysis of the time it takes for the gluttonous civilization to fly to the earth, and when the gluttonous fleet appears in the outer space of the earth, the earth faces a threat, how can we defend against it?"
