Chapter 264, Special Geographical Phenomena

"The thickness of AB star's atmosphere reaches 100 kilometers, and it also has an ozone layer. The oxygen content in the atmosphere reaches 25%, which is a few percentage points higher than the oxygen content in the atmosphere on Earth, but it is not more than 30%, so it is There’s no need to worry about oxygen poisoning.”

"In addition to oxygen, there is 73% nitrogen in the atmosphere, and the remaining 2% is composed of carbon dioxide, water vapor, and rare gases. No large amounts of gases that are toxic to the human body have been found."

"The composition of this atmosphere is very similar to that of our earth's atmosphere, except that the oxygen content is higher and the nitrogen content is less. It's perfect!"

Soon, detailed data on the composition of the atmosphere on AB star came out. After everyone saw this data, everyone smiled even brighter, because the proportion of atmospheric composition here is almost the same as that on the earth, and even because of the oxygen content. It is a few percentage points higher, so if you breathe on this planet, the air will be fresher.

"I have to say that this is a gift from the universe to us descendants of the Yellow Emperor. This planet is so perfect. If the virus is not considered, we can even land directly on this planet to live."

Tang Boyuan sighed with a smile.

"There is no solution to the virus. As long as we can develop the corresponding vaccine, we will be able to have the same immunity as the indigenous people in a short period of time. By then, we can safely settle on this planet."

Gu Feng smiled and nodded. Although biological viruses are scary, modern technology is also very powerful in studying viruses. One of the most effective ways to deal with viruses is to develop corresponding antibody vaccines.

"This matter will be left to you. Everyone wants to visit this living planet as soon as possible. Tsk tsk, this planet is completely opposite to our earth in some places."

"We have an equator on the earth, then the north and south poles, and two cold zones. However, this planet is exactly the opposite, because it neither revolves nor autobiography. It obtains energy from two stars, so the place where the stars above AB are directly shining Two hot poles are formed, which are cold spots similar to the north and south poles of the earth, except that the ones on this planet are tropical areas. "

"Then as the star's light slowly changes from direct to deflected, the temperature on the planet's surface also gradually decreases. The temperate zone and the cold zone. What is extremely interesting is that the cold zone on this planet is the same as the equator on our earth. It is surrounded by of the entire planet, not in terms of poles.”

Tang Boyuan pointed to the AB star simulated on the monitor. There was a white circular line surrounding the entire planet. This was the cold zone on the planet. Then there were two red areas. These areas were areas directly illuminated by the star's light, that is, on the planet. tropics, but there are two of them.

"Two tropical zones and one cold zone, just opposite to the earth?"

Luo Xiaoyao raised his eyebrows when he heard this.

"Yes, with this cold zone as the boundary, the entire planet can actually be divided into two hemispheres. The eastern hemisphere is illuminated by the light of Star B, and the western hemisphere is illuminated by the light of Star A. In this cold zone You can see two suns in the sky above the line, and it is always daytime on this planet, there is no night.”

Tang Boyuan nodded and told the very interesting part.

"And the life on the entire planet is also very different because of the isolation of this cold zone. The Eastern Hemisphere is relatively close to Star B and is more affected. The temperature is relatively better, so life in the Eastern Hemisphere is more prosperous. , because the western hemisphere is farther away from the light of A, so the climate here is relatively colder, and the area of ​​the frigid zone is larger. "

"Another interesting phenomenon is that the life on this planet has the habit of collective migration, because the two stars also rotate with each other, with this planet as the center point, and the rotation period is about 360 years. During the long history of life evolution, life on this planet has also developed a tendency to follow this change. "

"So they will slowly move in a pattern, from east to west. Please look at this place. This narrow area connects the east and west hemispheres with a long and narrow corridor. This area is moving all the time. There are animals migrating from east to west.”

"This may be a phenomenon that is really not conducive to our survival on this planet, because it means that we have to migrate every few hundred years. Otherwise, what you live in now is in the tropics, and in a few hundred years it will become It has become a cold zone. I think this is why this planet is very suitable for the reproduction and development of life. However, it is an important reason why the civilization here has always been relatively primitive, because it takes hundreds of years to migrate across the entire planet. This is It greatly delayed their development time.”

Just from some basic things on this planet, Tang Boyuan analyzed the strange phenomena on this planet, and also analyzed the important reasons why the speed of development of civilization here has always been in the primitive civilization stage.

As time passed slowly, the "Kyushu" spacecraft got closer and closer to the AB star, until it finally reached the outer space of the AB star and began to park here in outer space.

"hurry up!"

On the spacecraft, small anti-gravity spacecrafts in the shape of flying saucers kept taking off. These spacecrafts flew very fast, flew into the atmosphere of AB star, and headed straight for various places on AB star, ready to collect samples from all over the planet, especially the most important virus samples, because in order to develop virus vaccines, the virus must be studied and analyzed.

On a vast grassland in the eastern hemisphere of AB star, the grassland is lush with trees and grass, and various animals live very leisurely on the grassland. The largest number of them are animals similar to cows and sheep on Earth. They don’t look very different in appearance, but their reminders are much larger than those on Earth. Any one of them can be comparable to the big buffalo on Earth, and the large ones can be compared with the elephants on Earth.

In groups, they multiply and thrive in the dense grass of the grassland. On the grassland, large carnivores chase their prey. Some of these carnivores are very large, far exceeding the lions and tigers on the earth. They are fast and agile, and their bloody mouths have a very strong bite force. They chase their prey comfortably in the dense grassland.

In addition to these animals, the sky is also extremely cruel. Large birds of prey are hunting small birds. Some birds of prey are very large. When their wings are spread out, they are more than ten meters. They glide in the sky at a high speed like an airplane. A dive or even directly attack various animals on the ground, even large carnivores are not afraid at all.

In the dense grass, a group of short primitive indigenous people holding spears, stone axes, sticks and other weapons quietly sneaked in the grass to approach their prey targets. This time, their prey is a huge buffalo-like animal like an African elephant. At this time, the buffalo is still leisurely eating grass, not noticing that it has become someone else's prey.

"*&&…………"

The native leader saw that the time was ripe, so he stood up and gave a loud order. The natives who had been surrounded on all sides suddenly emerged, and the spears in their hands kept flying out, forming a rain of spears flying towards the frightened buffalo-like animals.

Most of the spears were bounced off the thick skin of the animals, and only a few were inserted, but they were not very deep, just some skin injuries. The injured animals took a step forward and ran wildly. The natives did not dare to hit them head-on.

However, these natives often hunted this kind of animals for food, so they were well prepared. Some natives used long trees as trip ropes and set traps in front of the buffaloes. The buffaloes were tripped by the trees while running fast, and the bones in their legs were broken. They could only crawl on the ground, and were finally stabbed to death by the natives with spears.

The natives used stone axes, stone knives and other tools to cut the large animals apart, and then happily carried large pieces of meat back to their camp. In their camp, there was a group of hungry children waiting for food.

There was no distinction between night and day on this planet, because the sun was always in the same position, so it was always daytime. When they returned to the camp, the bonfire soon rose again, and large pieces of meat were put on the rack. Under the smoky fire, they gave off an attractive aroma. The primitive natives gathered together and began to sing and dance to celebrate this harvest.

Just as they were full and fell asleep and rested, a flying saucer-shaped spaceship descended from the distant sky. The spaceship slowly approached their camp and soon stopped. The hatch of the spaceship slowly opened, and teams of earthlings wearing space suits and armed with live ammunition walked out and headed straight for the natives' camp.

"**……&"

A burst of alarms sounded, and the primitive natives who were on guard finally found out. He shouted in panic. Originally, there was a fire, and wild animals and so on did not dare to approach the camp, unless they were very hungry and dared to come to steal some food, but now these animals that had never been seen before actually ran straight to their camp, obviously with bad intentions.

Soon the natives were awakened, picked up the stone axes, spears, etc. in their hands and prepared to fight, ready to defend their homes and families, but they had not yet had any contact with the enemy, and saw these natives slowly fall down, and the remaining natives were frightened and kept running away in the bushes on all sides.

"They actually let a few of them run away, but they caught dozens of them, big and small, old and young, which is enough for experiments."
