Universe dominance

"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 taken into consideration, 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 a 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 upon hearing 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 flying saucer-shaped anti-gravity spacecrafts were constantly taking off. These spacecrafts were flying at very fast speeds, flying into the atmosphere of the AB star, heading straight to various locations on the AB star, preparing to go Collect samples from all over the planet, especially the most important virus samples, because in order to develop a virus vaccine, the virus must be studied and analyzed.

In a vast grassland in the eastern hemisphere of Planet AB, the grassland is lush with trees and grass. Various animals live a very leisurely life on the grassland. The largest number of them are animals similar to cows and sheep on the earth. Animals don't look very different in appearance, but their size is much larger than here on Earth. Any one of them can be compared to a giant buffalo on Earth, and the larger one can even be compared to an elephant on Earth.

Groups of large carnivores thrive in the dense grass of the grassland. On the grassland, large carnivores chase their prey. Some of these carnivores are very huge, far exceeding the lions on the earth. Tigers are fast, agile, and have a very powerful bite with their huge mouths. They chase their prey comfortably in the dense grasslands.

In addition to these animals, the sky is also extremely cruel. Large raptors are hunting small birds. Some raptors are so huge that their wings spread out to more than ten meters. They are as fast as an airplane in the sky. It can glide, dive or even directly attack various animals on the ground, and is not afraid of even large carnivores.

In the thick grass, a group of short primitive aboriginal people, armed with spears, stone axes, sticks and other weapons, quietly sneaked into the grass to approach their prey target. This time, their prey was a huge African elephant. A buffalo-like animal, this buffalo was still munching on the grass leisurely at this time, without even noticing that it had become someone else's prey.

“*\u0026\u0026………”

Seeing that the time was right, the indigenous leader stood up and issued a loud order. Suddenly, the indigenous people surrounded by him suddenly emerged from all sides. The spears in their hands kept flying out, forming a shower of spears and flying toward the already frightened people. Buffalo-like animal.

Most of the spears were bounced away by the thick skin of the animals. Only a few were inserted in, but they were not very deep. They were just some skin injuries. The injured animals even opened their hooves and ran wildly. Get up, the natives don't dare to collide head-on.

However, these indigenous people also often hunted this kind of animal for food, so they were well prepared. Some indigenous people used long trees as tripping ropes and set up traps in front of the buffalo running. The buffalo running rapidly were caught by the trees. As soon as he tripped, all the bones in his legs were broken, and he could only crawl on the ground. In the end, he was slowly stabbed to death by the natives with spears.

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

There is no distinction between night and day on this planet, because the sun is always in the same position, so it is always daytime. Returning to the camp, the campfire soon rose again, and large pieces of meat were put on the rack and burned in the blazing fire. The roasted meat gave off an alluring aroma, and the primitive indigenous people gathered together and began to sing and dance to celebrate the harvest.

Just when they had eaten and drank enough, and fell into a deep sleep and rest, a flying saucer-shaped spaceship descended from the distant sky. The spacecraft slowly approached their camp, and soon parked, opening the door of the spacecraft. Slowly opening it, groups of Earthlings wearing space suits and armed with live ammunition came out and headed straight for the indigenous camp.

"**...\u0026"

A burst of sirens sounded, and the primitive aboriginal man who was on guard duty finally discovered it. He shouted in panic. There was originally a fire, and wild beasts, animals, etc. did not dare to approach the camp unless they were very hungry. He dared to come over and steal some food, but now these people he had never seen before came straight to his camp, obviously with bad intentions.

Soon the natives were awakened, and they picked up the stone axes, spears, etc. in their hands and prepared to fight and defend their homes and families. However, they had not yet had any contact with the enemy. I saw that these natives soon slowly After falling down, the remaining natives were frightened and ran away in panic into the grass on all sides.

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