"Professor Shen, do you have a specific study of this world?"

Zhang Zhen waved his hand, motioned to the soldiers next to him to help Professor Shen sit in his seat, and asked very respectfully.

After all, the professor in front of him is at the same level as Zhang Zhen when it comes to military ranks, and he enjoys the treatment of the rank of national general, and his qualifications are even better, so he naturally will not show his momentum in the face of those soldiers.

"Well, although I don't understand the mechanism of this world, I have studied the entire structure of it."

Shen Ningzhen's wrinkled face showed a smile, revealing the restraint of a scholar, handed the USB flash drive in his hand to the student next to him, and motioned him to insert the USB flash drive into the central projector, and on the central projector, this existence that Yue Xiao called the Yuan Spirit Realm immediately appeared.

An artificial sun is suspended in the center, surrounded by endless oceans and continents, similar to the world of Dyson spheres.

That's right, the world that Zao Wou-Ki traveled through is not a planet, and there is no star map for observation, because this is a semi-closed nature with ecological cycle ability, and for the time being, it is a shell-like world called a Dyson sphere that is beyond the reach of human current technology.

"Guys, this is the world across from us. It has a diameter of 12,000 kilometers and a mass of about 7.37*10^22kg, which is the same size as the mass of the moon. The sun hanging in the center of it is about 100 kilometers in diameter, although its size is small, it occupies 90% of the mass of the entire Yuan Spirit Realm, and its energy released per second is about 1.7x10^17 joules, which is equivalent to the energy we receive from the sun. As for its longevity, it is not yet known. ”

"Well, Professor! May I ask a question? I remember that the lower limit of mass for the formation of stars was 0.08 solar mass, so why would this artificial sun be able to carry out nuclear fusion reactions with such a low mass? ”

The mass of the sun is 1.9891*10^30kg, which is 330,000 times the mass of the earth, and the mass of this artificial sun is only equivalent to three millionths of its mass, and such a mass has to be said to be too little.

"The reason is unknown. However, the simplest explanation is that the sun is man-made, so it can use its own control system to restrain this artificial fireball with a diameter of 100 kilometers, and make it continue to carry out nuclear fusion reactions steadily. Shen Ning really smiled, but his words suddenly became cautious: "Of course, I hope this thing is not made by aliens." ”

"But what's the matter with the night? After all, if it is designed according to the Dyson sphere, then there should be no night. ”

"Quite simply, because we found these things on its surface."

As the slides on the projector switched, a structural drawing showing an artificial sun appeared.

In this picture, you can clearly see the entire surface of the sun, which is wrapped in a black substance, making it unable to emit dazzling light.

Shen Ningzhen also pointed to these slides and said word by word: "According to measurements, the area of these materials is exactly half of the sun, and the surface temperature is only 300 degrees Celsius, far lower than the high temperature of 6,000 degrees Celsius on the surface of the sun. It is these substances that continue to move steadily on the surface of the sun, thus creating the phenomena of day and night. Of course, we haven't analyzed these black substances either, but for the sake of caution, let's think it's an extraterrestrial product. ”

"I see! No wonder I think the sun in the sky doesn't move? I see! ”

"That's true. Beyond this sun is the ionosphere, which stretches for thousands of kilometers. ”

"Because of the radiation ejected from the sun, high-energy charged particles, solar wind, etc., the whole area is in a state of extreme chaos. All kinds of rubble, high-energy particles, meteorites, plasma plasma, lightning, etc., are constantly generated in this area. From 300 kilometers above the ground, the temperature exceeds 300 degrees Celsius, and the higher the altitude, the higher the temperature. It is precisely for this reason that our reconnaissance satellites cannot operate normally in an area of more than 300 kilometers. ”

Shen Ningzhen said this, feeling a little thirsty, so he drank a glass of water and continued to explain: "More importantly, dangerous objects such as meteorites, high-energy charged particles, and plasma will fall from the sky occasionally, so even if it is a dangerous area above 20 kilometers, it is difficult for even our most advanced aircraft to sail in this area. ”

"So, the world might be man-made?"

When Zhang Zhen heard these materials, he also felt frightened.

Because if he can build such a civilization in the world of Dyson Sphere, he is not sure that he will be able to defeat the other party.

After all, the gap between the two is too big, and it is difficult to make up for the gap between modern society and primitive society.

"Not sure." Shen Ningzhen shook his head and said with a wry smile: "After all, according to the information we have, this world is still in the medieval feudal era, and there is no unified government. Maybe it was abandoned by some accident. It's like those abandoned cities, but this time it's just a world that has been abandoned. ”

"What about the whole world?"

"Although because of the ionosphere, we can't fully detect it. However, after rough calculations, it was found that the crust was composed of six continents. Its total area is about 28 per cent of the total surface area, making a total of 130 million square kilometers, with the smallest being 13 million square kilometers and the largest being 25 million square kilometers. And between the continents, it is covered by a vast ocean. Since there are no specific measurements, it is not clear exactly how deep. ”

"Well, thanks to the professor's guidance, I'm more sure of that."

Zhang Zhen looked at the information that had been sorted out, and after seeing Shen Ningzhen go back, he turned his eyes sideways and looked at Zhang Yue next to him, and asked, "That kid Zao Wou-ki, hasn't he occupied Cangbei City yet?" ”

Zhang Yue shook his head and said, "No! ”

"Didn't he ask us for support either?" Looking at the table, Zhang Zhen became more and more serious.

Zhang Yue put a stack of printed paper in front of Zhang Zhen, his eyes swept slightly from Zhang Zhen's face, and he knew that his leader was in a state of thought at the moment. He didn't dare to express his opinion, but just stood aside and said calmly: "No." However, Cheng Zheng sent back the information they had gathered. It's about the distribution of forces in the entire Cangbei City. ”

"Is there any information on the distribution of forces?" Zhang Zhen flipped over, and his mouth was lukewarm: "This guy is somewhat useful." ”

Zhang Yue retreated, his eyes swept over the sand table that had already been prepared next to him, and on this sand table covering a radius of thousands of miles, except for the five major villages and Cangbei City, every ravine-crisscrossing mountain range was marked on it with those chess pieces that were used as signs, and anyone could clearly see the specific situation of the entire Cangbei City.

He asked, "Then may I ask if we are still going out now?" After all, according to Cheng Zheng's report, Major Zhao has not heard from him for three days. ”

"Three days? What exactly is Zhao Boy doing? ”

Zhang Zhen faintly felt that something was wrong, and suddenly felt that the thread he was originally tied to Zao Wou-Ki had become extremely fragile, and even had a feeling that he couldn't control it.

Even so, he didn't care, the left and right were just a small soldier, at best a pawn used to eradicate the enemy.

"I don't know. After all, he's not the same as we are now. Within him, however, there is an otherworldly power. Zhang Yue said.

", is this guy going to use our power to gain the power of the other world? This damn boy is a little cautious. Thinking of this, Zhang Zhen couldn't help but secretly curse "elf ghost", and immediately understood what Zao Wou-Ki planned to do.

With the help of the army, to obtain enough to improve his strength, Zao Wou-ki's purpose from the beginning was this.

He himself is just a big soldier, he has been a soldier for eight years, and after a hundred battles, he is only a lieutenant rank, and there are a lot of military merit medals, but the so-called military ranks have always stagnated, and all the so-called qualifications and connections in the army have long been clearly seen.

So he volunteered to accept the task this time, that is, to use this merit to completely change his current disadvantage.

Since he can't compare with those proud sons who were born in Jiangmen in terms of connections and relationships, he can gain enough power in this otherworld that is enough to change all the status quo, and he may be able to completely change his fate as a low-level soldier.

Zao Wou-Ki had already understood this when he broke into this world and accepted this otherworldly force.

Zhang Yue let out an "um" and asked again, "By the way, General." That being the case, what do we do next? ”

Although his attitude was respectful, he couldn't help but flash a hint of mockery when he swept through the people in the command room.

When the investigation was first carried out on the other world, many people enthusiastically asked to participate, but after seeing the combat effectiveness shown by the indigenous girl, they immediately began to refuse when they were surprised, after all, the situation in the other world is unknown, and there is such a powerful individual existence.

They don't carry anything with them, and they just come to the other world by their own bodies, isn't that waiting for death?

Among other things, the toxins contained in those strange plants and animals alone are enough to easily bring a person down. They are not mentally retarded enough to lose their lives here in order to steal merit.

For this reason, Zhang Zhen also had to wake up Zao Wou-Ki and let this brave and skilled warrior go on a reconnaissance mission.

"Attack! After all, according to intelligence, the United States of China and the Great Song Empire have already begun to enter the other world. In order to prevent the other side from occupying the Atlas, we need to start acting immediately. There is no time to wait any longer. Zhang Zhen did not hesitate, swept over from the command room, and immediately ordered: "The 337th Mobile Combat Brigade is immediately ready, and in twenty-four hours, it will immediately launch an attack and completely occupy the intended target." ”

"We got it."

For a moment, the entire staff members immediately got busy, passing on the various orders and preparing to start further operations.

The 337th Heavy Mobile Combat Brigade, composed of 58 LZT99 "Xuanwu" main battle tanks, 102 BBZ-93 "Weasel" infantry fighting vehicles, 42 BYS-87 "Swift Mouse" armored personnel carriers, 16 self-propelled howitzers, 165 information equipment, and 764 logistics support equipment, totaling 3,400 people, is also ready to completely take over the entire Cangbei City in one go.
