The Swift Sword, rapier, was popular in the late 16th and 17th centuries of the Earth, and the King of Armorless Duels. Its biggest feature is its gorgeous handguards and a slender sword body. In many people's impression, the Swift Sword is mostly

It is called a thin sword or a stabbing sword, and the sword body is extremely elastic and has only the function of stabbing. It is more gorgeous than the tough and simple long sword, and is marked as a "woman's sword".

After all, Xunjie Sword is commonly seen in the hands of female characters in most film and television entertainment works, so it is no wonder that ordinary people have this impression.

But in fact, the real Swift Sword's body is not soft, and it is not a slender cone, which loses its ability to chop. The cross-section of the Swift Sword's sword body includes the early flat triangle, which later developed into thick and

The narrow hexagon is like a long sword after losing weight, which strengthens the stabbing ability and weakens the chopping ability. The sword body of the Swift Sword is very hard. Although the chopping ability is not as good as the long sword, it cannot face armor.

The body of a person is still extremely threatening.

It has the flexibility and the protection ability of the opponent that the long sword has never had. The gorgeous handguard is the key to protecting a swordsman from being knocked out by the enemy. At the same time, the Swift Sword has the length and weight of the long sword, but

It is a one-handed sword, a complete "man's sword".

"So how can these women in the Terra world play these weapons so smoothly!"

Valentine yelled in despair in her heart, and her face under the mask had already been soaked with tears (crossed off) sweat.

"Because men are unreliable, women can only be forced to take up weapons." Kaoru Zhengyu said an extremely feminist statement in Valentine's mind.

"I think men in this world are very good and handsome. Look, aren't that what I am like?" The appearance of Jiao Zhengyu's voice calmed Valentine's restless heart. Every time he talked to the system, he said

You can feel a sense of security from the bottom of your heart.

"You are not handsome, you are beautiful."

Jiao Zhengyu teased and continued to spread knowledge about the Terra world to Valentine.

"I remember I said... Oh, did I say it? No, it doesn't matter... How many people do you think there are about Terra world?"

Jiao Zhengyu did not want to tell Valentine directly, but set up a suspense.

"What I hate the most is a bastard like you who doesn't say everything at once and ask the audience specifically. I just want to know the answer, so don't be interested in guessing riddles at all, okay?"

If Kaoru Zhengyu appeared in the real world, Valentine would definitely point at his nose and yell out this sentence.

Suffering one's appetite is really one of the worst things in the world, it's as half of talking and out of context.

"This world is bigger than you think, but the number of people is much smaller than you think."

Kaori Zhengyu ignored Valentine's inner complaints and began to explain his "Terra World and Population" ppt.

A god-loving Valentine's consciousness appeared in the spiritual space. Under the white light of the horizon, a pure wooden table with yellow all over the body appeared in front of him, and a bench with the same style as the table appeared behind him.

"Your desks and chairs in high school are to remind you of that boring but carefree good time again." The Filin-shaped Kou Zhengyu appeared a few meters ahead of Valentine, and he was still at hand.

A blackboard appeared.

"I don't think this environment will remind me of the good times in high school." Valentine looked around and felt cold and silent.

But soon, in just a blink of an eye, the mental space changed.

Pure white walls, ceramic tiles over one meter high, desks filled with books, Valentine raised his arm, he could see all kinds of scratches on the desk, and the black edges left by time

Traces. The window on the right is very large, with front and back. There are three square glass installed in the window, which can be opened on the left and right sides. The door is a relatively small type, yellow, and can accommodate up to two people entering and exiting at the same time.

The lock was hung on the handle behind the door, and thick transparent tape was wrapped on the other side of the door switch, probably to make the door close tighter and avoid air leakage.

The floor was dirty, and the marble tiles were soaked with black gray. The sycamore trees outside the window were swaying, and the golden sunlight shone into the classroom through the gaps between the leaves, shining on Valentine's desk. The cicadas were chirping.

Rhythmically, Valentine's ears echoed continuously. There was no air conditioner or fan in the classroom, the air was stuffy, and even the famous aphorisms hanging on the walls were distorted by the high temperature.

Valentine's clothes were very simple, with a black and white coat, with red lines on it, and the collar was also bright red. Valentine's brain tingled in the sun, and she felt a warm current rushing into her nose.

The clothes are simple, not beautiful, or even ugly, but they carry his most tense and relaxed memories.

He blinked, suppressed the bitterness in his heart, and turned his head to look at the podium. The Jiao Zhengyu on the podium still looked like a Philin tribe, with a white-haired cat-eared boy. However, the clothes on his body had turned into white shirts and

The combination of trousers and the belt reveal a familiar and cheap feeling.

This was the most common dress for male teachers in that era, both young and old.

Puff.

Valentine sniffed and laughed out loud.

"It feels strange to wear this outfit when you are so young."

Too old and too ordinary.

It doesn't match the Harvard-Yale-level appearance at all.

"Didn't you say that the environment just now won't let you recall your wonderful high school days? In order to meet your requirements, I deliberately turned into this and restored it according to your memory."

He raised his hand to his neck and swung his clothes down.

"Even I restored the teacher's clothes."

"That's why I feel strange..." Valentine responded blankly, speaking faster, and it seemed that she was immersed in memories.

"Okay, Valentine... should be said to Chen Yue, don't talk now." Jiao Zhengyu knocked on the blackboard.

"Study is now on, close your mouth."

Valentine raised her hand and touched her head, her cold horns still pointed directly at Yunxiao on both sides of his head.

"You'd better call me Valentine..."

"Well, Valentine, stand me up, who gave you the right to speak in class?"

A ruler appeared in Jiao Zhengyu's hand and knocked on the blackboard.

Valentine smiled bitterly and shook her head, and stood up.

"Very good, this lesson is very short. It mainly talks about some knowledge about the Terra world, and it is also to let you understand the world just right." Jiao Zhengyu put down the ruler in his hand and opened two small pieces in the middle of the blackboard that can be moved.

blackboard.

There is a large white display inside, directly connected to the computer on the podium.

After a light mouse click, a picture appeared in front of Valentine.

A planet with blue and green tones, with some white and large yellow in green, which looks the same as the earth, but the shape of the continental plates can only be said to be similar, but there are still some differences.

"This is the world of Terra, a planet similar to Earth." Gonemae tapped the display with a ruler.

"It looks like there is no earth green." Valentine carefully observed the planet and gave his evaluation.

"And the sea is a little dark?"

"It's true." Kaoru found a continent to enlarge it. Two-thirds of the entire continent were yellow and very few green.

But it is worth noting that these yellow plots contain a lot of blue thin lines.

That's a river.

"Because of natural disasters, the environment in this world is not as good as you think, and is much worse than the earth."

"But the wilderness also provides another convenience for people in this world without any obstacles."

As the picture turned, an aerial picture of the Rhode Island base appeared on the display.

"Human active stones are technical, the ground is smooth and without obstacles, and are often threatened by natural disasters, so mobile cities emerged."

"But their technology does not exceed the level of the Earthlings' technology. The reason why mobile cities can succeed is because of the existence of the Source Stone."

"Uh... the strong bricks fly?" Valentine remembered a word.

"That's right." Kaoraki snapped his fingers, and the picture changed again.

Countless black pipes spread in the picture, like spider webs. At the center of the web, a transparent square container connects all the pipes. In the container, a huge source stone lies there. The source stone The color is very bright and the purity is definitely not lower than the level of purity.

"In order to make it obvious, I have specially made that core transparent. You can't actually see the source stone inside the real core."

"To be honest, I think if the Earthlings had the active stone, the first solar system war would have begun." Valentine scratched her head.

"In terms of the nature of the earthlings, it should be the second solar system war."

Ghost Journey knocked on the mouse, and the picture changed again, turning into a photo of Rhode Island operators.

"The natural disasters have made mobile cities popular, and the source stones left behind have promoted the development of the Terra world. In just a few hundred years, they have given them technology that surpasses the people on earth."

"But during this period, new problems arose."

“Population problem.”

"The world of Terra is about the same size as the earth, with a ratio of land to oceans of 4:6, which means that the land of this world is larger than that of the earth."

"Is this why some people in this world have never heard of the ocean..."

Valentine murmured to herself.

"But the total population is only one billion."

"Mobile cities and natural disasters and ore diseases have limited the rapid growth of human beings, and the annual growth rate of human beings in the Terra world has so far remained at 0."

"A baby was born in one place, and someone died in another place under natural disasters."

"Of course, one billion humans are not a problem." Ghost Yu shrugged.

“The real problem is the ratio of men and women.”

Two huge numbers appear on the screen, blue 1 and pink 2.

“1:2.”

"A billion people, 66% of them are women."

"...Is this paradise?" Valentine seemed to see a bunch of girls waving to him.

"To some extent...yes. Because people in this world have a special gene, I don't know if those medical researchers have discovered this thing. Here I named this gene 'appearance gene'. ”
