Technological Empire of the City

In Xingyue Nation’s laboratory, Xiaowen reported on the new trends of various countries. All institutions are preparing for the coming of the interstellar age. This made Zhang Yu a little anxious. Although she believed that she could fly out of the earth sooner than other countries, it’s something. There will always be a case, if it is surpassed by another country, your own myth will be broken.

From then on, the advantages of the Star-Moon Nation will no longer be obvious, and the countries will not be so afraid of the strength of the Star-Moon Nation. Zhang Yu cannot allow this to happen, so he has also begun to passively develop better interstellar spacecraft. But the suspension technology has been immature, and the anti-gravity engine has no clue.

"Ugh". Zhang Yu sighed when he thought of this.

After seeing Zhang Yu's dull appearance, the three Shi Xi asked suspiciously.

"Teacher, do you have something on your mind".

"Teacher, we are very strong. Tell me if there is anything difficult."

"teacher".

Zhang Yu glanced at the three of them, then shook his head and said, "You can't do it yet, the technology is too bad."

The negative words made Shi Xi and the three people very unwilling. They said to Zhang Yu firmly with all their faces: "We can, let's try."

Seeing the determined expressions of the three of them, Zhang Yu could only explain: "The anti-gravity engine has been clueless, can you help?"

"Uh". The three people of Shi Xi were completely dumbfounded. They didn't even understand the levitation technology, and they didn't know any anti-gravity technology.

"--". Upon seeing this, Zhang Yu shook his head and stopped talking, because Zhang Yu had no expectations of them.

The dejected Shi Xi trio, after looking at each other for a few times, still felt very unwilling, and began to look for the theoretical knowledge about anti-gravity to watch, an article about "relying on the reverse gravitational field formed by the machine itself to offset or block the external environment The book about the gravitational field gains thrust] completely indulged the three of them.

Mei Xue flashed a bright light in her mind and asked eagerly: "By the way, what is the theory of levitation technology".

"The reaction force of high-frequency electromagnetic drives the machine into the air." Xu Bo and Shi Xi didn't understand and couldn't speak. Zhang Yu, who was meditating on the side, heard the question and explained without thinking about it.

"Can't anti-gravity use high-frequency electromagnetic fields?" Mei Xue asked.

"No, the levitation force generated by the high-frequency electromagnetic field is too low to lift objects weighing several thousand tons into the air." Zhang Yu muttered in thought.

"---". Shi Xi and Xu Bo were dumbfounded. They didn't expect Mei Xue to really understand the information.

"What about gravitational waves, how about using gravitational waves generated by a high magnetic field to push the device". Mei Xue continued to ask, her eyes bright.

"Uh". Thinking Zhang Yu heard the words, he woke up immediately and continued to analyze the possibility. The main nature of gravitational waves is that they propagate at the speed of light in a vacuum, carry energy and information related to the wave source. They are transverse waves, and plane waves at distant sources, the lowest. The second is quadrupole radiation.

This kind of radiation intensity is extremely weak, the absorption efficiency of gravitational waves by matter is extremely low, the penetration of gravitational waves is extremely strong, the earth is almost transparent to gravitational waves, and its polarization characteristics are two independent polarization states, etc., so gravitational waves are The gravitational field of wave form and finite velocity propagation.

In this way, there is still a good chance of using gravitational wave magnetic field to generate anti-gravity engines to succeed. Thinking of this, Zhang Yu exclaimed: "Good idea, let's start experiment."

"Yes". When Mei Xue heard that Zhang Yu had really adopted this idea, she smiled happily.

"---". After Shi Xi and Xu Bo saw this, they were very envious, and they wanted to be admitted by Zhang Yu.

When Zhang Yu started his experiment, Liu Kai and others from the Meteorological Bureau in the Xingyue Country factory area, next to the evolution drug production plant, were full of decadence. Because three days passed, there was still no movement in the underground. Everyone felt that the shock wave three days ago was just an illusion.

Liu Ruo frowned and suggested: "Stop, or just forget it".

"No, I have to sort out the factors of instability." Liu Kai shook his head and refused.

Outside the temporary tent, after three days of hard work, the employees have lost the enthusiasm they had at that time. They all looked like a fool, chatting and farting. If this continues, Liu Kaixin will face the crisis of being distrusted by his subordinates when he takes office. Up.

At the same time, in the headquarters monitoring station, Shi Xianhai, who was dismissed, also heard that Liu Kai and the others had achieved nothing. He immediately said to everyone with a full face: "Look at it, I said it's okay. Follow him to sleep and eat."

The employees who remained in the monitoring station heard this and immediately replied.

"It's still a visionary in history."

"It's not fast to do things without hair."

"You are really wise."

"Can't say that, I'm no longer a bureau seat, maybe Liu will find something in a while, hahaha". Hearing this, Shi Xianhai replied with a smile on his face, as if to say another good thing about Liu Kai, in fact, he was hitting Liu Kai's decision and making him unpopular.

"Tattoo". Suddenly, there was a rush of footsteps, and an employee ran in and shouted: "I have discovered, I have discovered."

"---". Suddenly, all the surrounding employees looked at Shi Xianhai with weird faces.

"Uh". A few seconds later, Shi Xianhai, who was slapped in the face, was blinded.

A few minutes ago, next to the evolution drug production area, just as everyone did not believe Liu Kai, I saw a "didididi" sound in the tent on the monitor screen, and everyone in the tent reacted. He immediately looked at the display screen, and virtual pictures of three marine animals appeared on the screen.

"How is this going". Liu Kai was very puzzled.

"How can squid, crab, and a fish cause such a big shock." Looking at the display screen, Liu Ruo said blankly.

"No, look at the scale of the display." Suddenly, an employee shouted.

Liu Kai and others were unclear. So, they immediately looked at the proportions on the display screen: squid 1:60,000, crab 1:40,000, fish 1:50,000. The data surprised everyone. Such data showed that the monitor The actual length of marine life is 60 meters, 40 meters, and 50 meters. Such a behemoth is about the same size as the monsters that appear in the Bering Sea.

Liu Ruo stammered in panic: "How, how is it possible, there are such big creatures underground".

The employees also discussed in amazement.

"Could it be a problem with the instrument".

"Yes, how can such a huge creature appear underground".

"This unscientific".

In the noisy tent, only Liu Kai believed that there were huge marine creatures underground, because only in this way could it be explained why there were vibrations here for no reason, and the shock waves were so regular. Liu Kai calmed down quickly. , Ordered everyone.

"Hurry up and report the matter, our Xingyue country is in danger."

Upon hearing the words, all the employees responded with serious expressions: "Yes."

At the top of the headquarters, the correspondent in the monitoring station received the call. He only heard a few words before putting down the phone. After rushing into the staff studio, he panted and shouted: "I have found something, something has been discovered."

Shi Xianhai, who was beaten in the face, asked: "What did you find?"

"There is a monster underground, quickly report to the upper level." The correspondent yelled slowly.

"what". Everyone was stunned.

In the underground laboratory, Zhang Yu, who was doing antigravity research, was suddenly interrupted by Xiaowen, and suddenly asked in an uncomfortable tone: "What's the matter, can't I wait for me to finish the experiment?"

Xiaowen projected a figure, and reported with a serious face: "A monster was found under the Evolved Pharmacy Factory."

"what". Xu Bo and the three were stunned.

Zhang Yu's face changed greatly, and he shouted: "Activate all the robots to block the place, I will go over immediately."

"Yes". Xiaowen responded.

When Mei Xue heard that Zhang Yu was about to go over, she immediately stopped and said: "Teacher, there is danger, don't go."

"Yes, teacher, you can also remotely command here." Xu Bo suggested to Shi Xi.

Zhang Yu heard this, shook his head and said: "There is no danger there yet. I want to know why there are monsters under the Star-Moon Kingdom, so I have to go over. You don't have to persuade. Also, you have to prepare quickly. If the monsters show up, Open the gate of the base as soon as possible to allow citizens of the Star Rain country to settle in for refuge."

"Ok". The three of Shi Xi couldn't stop Zhang Yu, so they reluctantly responded.

After the order, Zhang Yu dropped his protective clothing, rushed out of the laboratory, and went to the suspension vehicle storage room on the back door of the headquarters. There were all the officials’ suspension vehicles parked here. Zhang Yu didn’t even look at it, and walked straight away. Next to the hovering car closest to him, he voiced his command: "Open the door."

"Drip the bottom layer password to start." The intelligence of the car is activated, and the door is opened by itself.

"call out". Soon, I don't know whose levitation vehicle was directly lifted into the air and flew away.

In the robot factory, the eyes of all the robots were lit up. They unplugged the chargers, lined up, and flew into the sky. The dense army of robots made all the pedestrians around the headquarters very strange. They felt something was wrong and talked loudly. Got up and said.

"What happened".

"How come all the robots are dispatched".

"It's not that other institutions will attack us again, right."

"---".

In the Xingyueguo No.2 villa, Tang Yan’s wristband hummed "didididi". When he opened the message, all the robots he managed were dispatched. This kind of thing made Tang Yan very worried because he was able to pass her command. Of the robots, Zhang Yu is the only one.

Uneasy, Tang Yan quickly dialed Zhang Yu's wristband phone, and murmured anxiously: "Pick up, pick up quickly."

After waiting for a few seconds, Tang Yan felt that it took a long time. After hearing the other end of the wristband was connected, he asked eagerly: "Brother Yu, what happened?"

"Unidentified monsters appeared underground on the other side of the factory. Prepare yourself. In case the monsters come out, you will bring all your loved ones into the headquarters as soon as possible, do you know?" Zhang Yu said in a serious tone.

Hearing this, Tang Yan didn't want Zhang Yu to worry, so he responded, "I will take care of them. Don't worry, you must take care of yourself."

"it is good". Zhang Yu responded and hung up the communication. ,, ..
