Although after research, Xuanwu actually has a complete and systematic operation mode. However, the energy required is completely beyond expectations, and if something goes wrong with the Xuanwu 900 kilometers underground, it is not necessarily known whether the people living inside can survive, and the people on the ground will definitely die.

You know, the radius of the earth is only about 6,341 kilometers, but Xuanwu occupies as much as half, if there is really any problem, not only human beings, but the entire earth may suffer.

But if the safest mode of floating is to use the almost infinite energy of today, human beings can create new excavation suits and overalls, so that they can not be affected by mining guns and those small cultural relics. At the same time, with the continuous deepening, the airtightness and heat resistance of the workwear, as well as the supply of people are a long line. Not to mention, this has to be dug 900 kilometers underground.

Such a time-consuming and energy-consuming project may not be able to be completed even if it takes 43 years for mankind to complete. Of course, the most fatal thing is the lack of academic qualifications and knowledge of these people left on the earth. Fortunately, after the assistance of Bing Shijue in the early stage and more than a year of collective learning, most of the people have also adapted to the new position and the acquisition of new knowledge.

It's just that now, Bing Shijue can't help everyone, but after having enough foundation, some of the original high-energy consumption technologies have also been redeveloped, nuclear fusion is used as a backup energy supply, and the private terminals of the Earth faction have also begun to go online.

In this terminal, people can choose any of the courses offered, and those who study and pass the exam can directly exchange contribution points. The contribution point is to be able to buy some daily necessities and food. Even if you complete the courses provided, you can get the qualification to enter Xuanwu earlier and enter the interior, and get a more stable position.

With such incentives, people's enthusiasm is naturally increased. And the current policy is to encourage people to learn, in the hope that people will grow in knowledge. Although it didn't work out in the short term, in the dead of night, almost everyone wore their graying glasses and listened to the lectures on physics, geology, and energy.

It was also after more than a year of data screening that the Earth Sect discovered the sinister intentions of the Star Sect. They were given detailed instructions on how to build and how to explore the alien ruins. But this is just an instruction manual, like a thick, detailed manual, telling you how to repair the phone, but the principle of the phone battery, the internal arrangement of the chip, and how the parts on each circuit board are made, I don't know anything.

Despite this, it is difficult for people to resist such temptations. On the one hand, as long as you enter the relevant program according to the instructions, the machine will start automatically, and the robots that help people live will continue to appear. The other is to start from scratch, from the beginning of the code to think about why the code is written the way it is, and what exactly each code does. What effect will be formed by the combination, and if there are any other notes that are not indicated.

Not only that, but also to understand the principles behind each machine, the mechanism by which the robot can do the work. It takes more than 10 times as much effort as before. People still prefer ease to hard work.

However, he had to learn, and there were more incentives and rewards after learning, and even Zheng Kai in Yanjiang City hinted that if he had just gotten past the first few years of human escape without any progress, he might abandon him on Earth.

Of course, there is no explicit statement, and there is no document. It's just that people catch something out of that frenzied wave of learning.

The days of Xuanwu's ascension passed day by day, and some people were still immersed in a relaxed time. Contribution points are distributed every month, and food is worry-free. The disadvantage is that there is too little entertainment content on the Internet, except for learning or learning. And with the shaking brought to the earth by the rise of Xuanwu a little bit, many coastal places have all appeared the phenomenon of river and sea flooding, and some regional earthquakes are also frequent, and those who still think that the starry sky faction and the earth faction are scams, or obsessed with thinking that the earth is safe and sound, and want to rule the earth in the end, have died in the waves, or in the building called the heavens and the earth.

On the 27th day of Xuanwu's ascension, the radio telescope where Bi Min was standing guard suddenly received a strong signal. The screeching sound continued one after another, causing him to frown as he patrolled the inner room.

"What's going on?" Tu Ran, who was patrolling the top floor, also heard something and asked over the radio.

"Colonel Bi, there is an alarm on the monitoring of the Moon Faction." The researcher, dressed in a white lab coat and with messy hair, watched as the computer printer was spitting out reports, "But I can tell you the rough picture, it was the telescope that detected 10 sun-like flashes on the moon." ”

"10 flashes? 10 nuclear fusions? Bi Min thought for a moment and asked, within the scope of his current knowledge, only nuclear fusion could burst out with such powerful energy. In addition, their Earth Sect can study nuclear fusion, and it is normal for the Starry Sky Faction of the two level 3 civilizations to have 10 reactors.

"10 fusion spacecraft, to be exact." The researcher said, handing over the report and computer-cleaned pictures to Bi Min, "The direction is not Earth, but Mars and the asteroid belt." ”

"However, the fusion spacecraft ......" Bi Min noticed a few of the most critical information, "If these fusion spacecraft fly to our earth, and then according to the previous technology level of the Star Sky faction, can they suppress the earth?" ”

"This ...... Colonel Bi, I'm a major in archaeology and astronomy, and I've just entered the school, so I don't know much about the parameters you mentioned. The young man in the white coat noticed that the folds on Bi Min's brow were getting deeper and deeper, "But I can inform the people concerned right away." ”

"As soon as possible." Bi Min nodded, picked up the walkie-talkie, and switched to a channel that only him, Tu Ran, and the core personnel of Yanjiang City could hear, "I may have to prepare to implement a follow-up plan." ”

When this radio wave was quickly transmitted to the walkie-talkie of the relevant personnel, a group of hurried scientists also came in front of Bi Min. After a year of intensive study, their academic qualifications and knowledge have at least superficially reached the level of graduate students. However, most of them are some current students.

"Starry Sky Sect......" Bi Min couldn't wait to peel off the skin and cramp the people of the Starry Sky Sect in his heart, those excellent scientists, all the experienced ones were taken away, and the remaining people still needed to be cultivated from scratch.

"Colonel Bi, here is the member we have found temporarily based on your question just now, and should be able to answer your question." After the introduction of the boy in the white coat, he left directly and began to get busy in his seat.

"My name is Sophia, a former student at St. Petersburg State University, and now I am the leader of the observation team of the Lunar Mission," a white-haired girl said to Bi Min in a proficient language, "Colonel Bi, listen to my colleague, you have something to ask me about the speed of ships in the universe, and Mars?" ”

"Yes." Bi Min couldn't help but breathe a sigh of relief when he saw the other party's fluent speech, and after simply repeating the question he had just asked, the white-haired girl named Sophia lowered her head, turned around and returned to her position on the side, and after taking a pen and paper and making a simple calculation, the original smile on her face disappeared.

"Bad news?"

"Very bad, according to the mapping of my colleagues......" Sophia waited for the printer to copy the materials, and simply circled two sheets of paper with a red pen, "You may not be able to tell that these ships are traveling at the speed of one hundredth of a light." ”

"So that means?" After Bi Min heard this speed, he was a little bit big.

"It may not be clear to you that the distance between Mars and Earth is not fixed." After Sophia found out about Bi Min's situation, her eyebrows raised slightly, but she still explained as simply as possible, "It's only 55 million kilometers when it's close, and it's 400 million kilometers when it's far away." ”

"If we consider the best-case scenario, the fleet sent by the stars will depart at the longest distance, and it will only take 37 hours to reach Earth." As Sophia spoke, the blood on Bi Min's face also decreased little by little, "In the worst case, you can reach the earth in 8 hours." ”
