Beibei roams the magical starry world

The blue Atlantic Ocean is sparkling, and the sea breeze blows across your face, bringing gentle freshness. Looking at the distant blue sky and sea water blending into one, a fast-moving small submarine recklessly cut through this vast blue silk curtain.

On the small submarine, Beibei, Xiaohui, Jack, Xiaosheng, Honghaier and other friends formed a fan shape. Facing everyone in the middle was the robot Xiaocong.

At this time, each partner holds a cup of chocolate ice cream in his hand, licking the ice cream while listening to the robot Xiao Cong telling the history of human civilization.

"Thirty thousand light years after leaving the Andromeda Galaxy, our spacecraft arrived in the solar system. The sun was our first stop. We discovered some suspected life forms in the core of the sun, but they did not activate the wisdom of life. This made us in this galaxy It’s not optimistic that intelligent life will be found.”

"After leaving the sun, we went to Mercury and Venus, but no intelligent life was found. Then we came to the earth. This is a magical place. In addition to living things of different sizes, there is also intelligent life. We are particularly excited about this discovery. ."

"We are prepared to observe the growth, reproduction and evolution of intelligent life forms and social civilizations for a long time, so we temporarily parked the spacecraft at the bottom of the Atlantic Ocean and established a research center at the bottom of the Bermuda Blue Hole."

“According to your current age recording habits, we came to the earth about 10,000 BC, when intelligent humans were in the transitional stage between the late Paleolithic Age and the early Neolithic Age.

"Do you want to see the society at that time?" Robot Xiao Cong asked

"Okay! Can you take us to that era?" Jack asked in surprise.

"No, it's data imaging. You can feel the social culture at that time in an all-round way."

"Let's all go over and have a look!" Beibei suggested curiously.

The friends also nodded curiously.

I saw the robot Xiao Cong taking out a few things that looked like motorcycle helmets. The difference is that there is an extra wireless antenna on the top of the hat. "Everyone put on the hats, put the seats flat, lie down on the chairs, close your eyes, Relax your whole body. We will go to Mesopotamia Civilization, Europe, North Africa, East Asia, and India. Look at the differences and similarities between different regions in this era. During the trip, everyone can discuss it with consciousness, our virtual time travel Let’s set off.” Robot Xiao Cong said

The friends worked very cooperatively to sink their consciousness into the digitally constructed virtual world. Everyone found that they were sitting on a time ship, with a blue sky in front of them, and an endless virgin forest and vast grassland with animals in the distance. Free-running, rugged mountains layer upon layer.

The time ship led everyone to the Mesopotamia, the first stop of this time travel. Below the spaceship were two large rivers, the Tigris River and the Euphrates River.

"I understand why it is called the Mesopotamia. This civilization developed in the area between the Tigris and Euphrates rivers." said the Wolf Spider Hawker Wasp who is very talented in geographical location.

"Corresponding to the current map, what countries are included in the Mesopotamia?" asked the robot Xiao Cong

Xiaofeng said confidently: "It's too simple. It is located in western Asia, including: Iraq, Syria, Turkey, Jordan, Lebanon, Israel and Palestine. Now these countries mainly produce oil and are the richest countries in the world."

"Look below, what is growing in the vast farmland?" asked the robot Xiao Cong.

"Wheat, barley, beans, vegetables, cotton, spices, daylily, papyrus, fruits and other crops." Bullet Ant said in a very professional manner.

"What's the problem?" asked the robot Xiao Cong

"It shows that they won't be hungry." Bullet Ant said.

"It shows that the land is fertile, the rain is abundant, the irrigation is convenient, the vegetation is rich, and crops were the main industry at that time. The development of agriculture guaranteed people's basic living needs, and also laid an important economic foundation for the future concentration of the population to form cities." Xiaohui said professionally. replied

"Answer all seven points correctly, 100 points." said the robot Xiao Cong.

"Look, there are many men wearing animal skins and skirts, holding stone spears in their hands. They are going to hunt with spears made of stone!" Fat Tiger said.

I saw that these people were thick and muscular, with protruding front skulls. Each wears ornaments made of beast bones around their necks, wrists or ankles.

"Let's go take a look too!" said the aggressive little bee.

So, the time ship followed this group of people, and suddenly a wild boar rushed out of the forest. Four hunters held four stone spears and stabbed the wild boar in front and on both sides. They heard four "bang bang bang bang" sounds. Two of the spear poles were broken, but four stone spears penetrated the wild boar's body.

The wild boar turned around and ran away. Several hunters followed the blood trail leisurely. After walking for more than half an hour, there was a wild boar lying in front of them that had lost too much blood. The hunters happily tied the wild boar to the spear pole and left happily. .

"Keep following and taking a look." Xiaopang said curiously.

Soon they came to a village-like place. The hunters handed the wild boar to the tribal leader. He first made a sacrifice and thanked the tribe's patron saint, and then divided the wild boar according to the contribution. Every household in the tribe got some meat. Everyone All very happy.

In the evening, many children drove groups of cattle, sheep, pigs and chickens back home. The adults carried the caught fish and discussed fishing techniques happily. The children were very happy looking at the wild boar meat on the table.

"What do these pictures mean?" asked the robot Xiao Cong

"It shows that hunting, herding and fishing were also the main industries of this era, and tribes were formed, and tribal leaders began to form rights and sacrifices," Beibei said

"Answer six key points correctly, 100 points." said the robot Xiao Cong

The time ship came to the commodity trading area of ​​a market town and saw many stalls selling various pottery, accessories made from prey bones, furs, etc. People barter to get what they need.
