"Perhaps, I can explain this!"

The deep voice remembered from behind Chang'an, Li Chang'an turned around in an instant, knelt beside Cao Yunhua, and looked hopeful.

"Isn't it really an evil one? Brother Cao! ”

Lieutenant Cao ignored his sudden cuteness, and beckoned Qin Shuang and Du Xiaoxiao to come closer.

Then groping in your trouser pockets, as if looking for something!

The little book that records the daily routine is gone!

Lieutenant Cao was seen getting up and rummaging in his jacket pocket. Xiao Xiao was puzzled, and from Lao Cao's movements, he instantly thought that what the other party was looking for was a small book that kept recording along the way.

"Cao Yunhua, don't look for your little book, have you forgotten? You threw it to the captain! ”

Ah!

slapped the door of the head, gave the little girl an embarrassing smile, and returned to her original position.

When the three of them got closer, Lao Cao took off the broken combat uniform and put the upper body on the wound on his buttocks, put on a relatively comfortable sitting position in the middle of the three, and stretched out his hands to gesture in the air.

"I have all studied physics, because the earth has rotation, there are days and nights, and the relationship between the sun's irradiation time and distance has a variety of regional environments!"

"Brother Cao, that's from Geography Middle School! Junior High School Geography! ”

Li Changan frowned, looking at Cao Yunhua's gaze full of weirdness, a person who can't even distinguish between physics and geography can really explain the strange climate and daylight here?

"Shut up, don't interrupt if the child doesn't understand!"

"Cao Yunhua, you go on, what's wrong with the rotation of the earth?"

Glared at by Qin Shuang, Li Changan pursed his lips and became well-behaved by the way.

Lieutenant Cao folded his hands into a ball and stretched out one of his fingers.

"We all come from different places in China, China is in the middle of the tropics and the cold zone, and there are various different environmental climates. Humid, warm, four distinct seasons! ”

"What are the reasons for the formation of climate, one is the difference in regional latitude, we all know that the tropics are at the equator of the earth, close to the sun, and the cold zone is close to the north and south poles, far from the sun, and the intensity of light is weak, so the relative temperature is much lower than the tropics!"

"Second, because of the atmosphere, the earth is shrouded in a layer of ozone, which is like a glass cover, which can ensure that the energy radiated to the earth escapes outward, so the temperature difference on the surface of the entire earth is not particularly large!"

"Let's talk about rotation again, the earth rotates once is a day, the day is divided into night and day, where the sun touches is day, and where it does not shine is night."

"And the division of seasons is because the earth revolves, affected by the galaxy stars, that is, the sun, and the galaxy planets, the orbit of the revolution is not a regular circle, but an approximate ellipse, in an elliptical orbit, the distance between the earth and the sun will also become different, so there will be four seasons of spring, summer, autumn and winter!"

Cao Yunhua gestured with his hands in the air, encircled his two arms around an elliptical planetary orbit, and kept explaining. Qin Shuang sat aside, her right hand supporting her head, and the light in her eyes flickered.

What he said can be described as easy-to-understand common sense, and any junior high school student on the street can be more detailed and complete than what he said.

Qin Shuang didn't comprehend the meaning of his words, but when he said about the rotation of the earth, a light seemed to flash in his mind, but he was interrupted by Li Changan. Thinking of this, he rolled his eyes towards Chang'an, and happened to be bumped into by Li Chang'an, who was scratching his head.

Li Changan didn't dare to provoke Miss Qin, after all, Miss Qin was notorious, and he had heard a little about it, so he simply stopped provoking it. After listening to Cao Yunhua's explanation of junior high school geography knowledge, he was confused, what is the relationship between the rotation of the earth and the revolution and the collision of several people?

"Brother Cao, what do you say about the rotation of the earth and us, our big sun hangs above our head without moving, and it took so long to find the water source in the boundless sand sea."

"Don't say anything else, I just saw the outside environment through the crack, and all kinds of sand and dust are blowing!"

Cao Yunhua glanced at Li Changan, squeezed his brows, and turned to look at Qin Shuang, the corners of his mouth curled.

"Still don't understand?"

Qin Shuang was stunned when she heard this, and there was something in Cao Dagongzi's words, which was obviously said to her alone. Of the four people present, only she and Cao Yunhua knew that they were on a different planet at the moment, and they were no longer on the original earth.

Could it be that Cao Yunhua is deliberately playing himself? Or do you want to spit out the truth at such a time?

raised his head and looked at Lieutenant Cao, the trace of defense in his eyes made Lieutenant Cao feel helpless for a while, and secretly said that this woman's mind was really extreme, and he had already told her so vaguely why the sun in the sky had not moved for so long, and there was no alternation of day and night.

"Cao Yunhua, do you mean that because the place we are in now is a planet without rotation and revolution in the setting of simulated war?"

A small voice sounded, causing Qin Shuang and Chang'an, who were immersed in their respective thoughts, to raise their heads suddenly.

"I'm not sure, but it's not much the same, we stretched at least thousands of kilometers from the time we landed to the time we were captured, but I saw only one climatic feature, so I'm sure that if we keep heading in a certain direction now, there will be a world covered in ice and snow waiting for us!"

Xiaoxiao was shocked by Lieutenant Cao's assumption, and exhaled a few hot breaths with a long mouth, with a bitter face.

"In other words, our area of action is equivalent to an Earth? With such a large territory, how did the captain find us! ”

"Don't worry, Captain Lu is a miracle worker!"

Lao Cao comforted the girl casually, which made Qin Shuang, who was still thinking on the side, think about it, and couldn't tell whether Cao and the others were sincere or false.

After listening to the small words, Li Changan got up and leaned into the fur-covered gap and looked up at the sky, at this moment the angle of the gap was no longer visible, but Chang'an squeezed half of his face on the steel fence like a scientist who wanted to confirm his conjecture, trying to rub a ray of sunlight.

Ignoring Chang'an's strange behavior, the two women moved back slightly, leaning against the railing, imagining a picture of Luthor shining on the entire globe, and the hope in their hearts became more and more diminished.

Qin Shuang leaned on the iron railing beside Lao Cao and asked in a low voice.

"What did you mean was that the planet we are on now is a planet that does not rotate or revolution?"

"Yes and no, to compare this alien planet with the earth, first of all, you have to know the shape of the earth, because the earth is an obvious oblate sphere, so the uplifted part is subject to more additional gravity, and the relationship between the yellow and red angles and the gravitational force of the planet causes the direction of the earth's deflection to be regular. And I don't know much about the planet we're on now. ”

"However, it can be assumed with a simple backward thinking, when we tried in the sea of sand, we inserted a saber on the shadow of Luthor's long knife, and the angle between the two shadows did not have any angle when it was placed, and when we observed it again after a long time, the shadows still overlapped, and the angle did not change to the naked eye!"

"This shows that the ground under our feet has not shifted at any angle. And for so long, there is really no day and night, which means that we have always been on this side of the sun! The endless sea of sand that stretches for thousands of miles is the best evidence of this hypothesis! ”

"All speculation can only show one thing, the seasonal climate of this planet, the time of day and night changes, is very long!"

"But what does this have to do with us falling into the hands of the orcs?"

Qin Shuang patted his smooth forehead, and finally understood the assumption in Cao Yunhua's heart, but he was extremely puzzled in his heart, no matter whether there was a rotation and revolution on this orc planet, what did all this have to do with a few people falling into the hands of orcs?

Lieutenant Cao glanced at the two teammates, saw that both of them were immersed in their own world, and did not bother, and said in a deep voice.

"I don't know how big this planet is, but looking at the appearance of the orcs, it shouldn't be able to stand the heat and cold, they are unlikely to build a base in the snowy region on the back, and there is no trace of any buildings in the endless sand sea, so guess that the location we are in at the moment should be at the junction of the tropics and the cold zone, a little more tropical!"

"Remember the poem I told Luthor when I was captured by the orcs?"

"Stay until the Double Ninth Day, and come back to chrysanthemums!"

"Well, is that it?"

Miss Qin listened attentively, and in an instant, she recalled the words that Cao Yunhua shouted when she was captured.

Lao Cao rubbed his nose, nodded in confirmation, and continued in his mouth.

"Along the way, I kept observing my surroundings and the slight changes in the climate, and from the moment I landed, I felt that my body seemed to be a little lighter! If you think about it, do you feel extremely smooth when exercising? ”

Without waiting for Miss Qin to nod,

"According to the law of gravitation, we can feel that the body becomes lighter, which means that the gravitational force of this planet is not as big as the earth, or more simply, the planet under our feet is not as big as the earth."

"A planet with negligible rotation speed, very slow rotation speed, and smaller than the Earth. Here, orcs can be used as a station, and there are not many places to build a base, only at the intersection of the tropics and the cold zone! ”

"At that time, in the endless sea of sand, I thought that if the orcs could only build a base at the intersection of two climatic zones, then as long as they moved in the direction of the shadow under the sunlight, they would definitely be able to find the location of the orcs!"

"That's what I really meant when I left Luther, Captain Luthor was a smart man who was good at miracles. He is also very stubborn, so as long as we wait patiently, he will inevitably appear! ”

It turns out that everything is under his control!

Qin Shuang has been shocked by Cao Yunhua's agile thinking at this moment, just by relying on a little bit of what he has seen and heard in life, he can guess so much information, although I don't know if what he said is really completely correct, but through the confirmation of his heart and reality, it is estimated that he is not far from ten!

And through Cao Yunhua's trust in Luther's tone, Qin Shuang felt extremely shocked while envious.

This!

Is it trust beyond words?
