"The thickness of the atmosphere of AB Star has reached 100 kilometers, and there is also an ozone layer, and the oxygen content in the atmosphere has reached 25%, which is several percentage points higher than the atmospheric oxygen content on the earth, but it is not more than 30% superdog, so there is 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, and no large amounts of toxic gases have been found to be human."

"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, which is perfect!"

Soon, the detailed data on the atmospheric composition on the AB star also came out, and everyone smiled brighter after seeing this data, because the proportion of atmospheric composition here is almost the same as that of the earth, and even because the oxygen content 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 the gift of the universe to our descendants of Yan and Huang, this planet is so perfect, if we don't consider the factor of the virus, we can even land directly on this planet to live."

Tang Boyuan sighed with a smile.

"The virus is not without a solution, as long as we can develop the corresponding vaccine, we can also have the same immunity as the indigenous people in a very short time, and then we can rest assured to settle on this planet."

Gu Feng smiled and nodded, although the biological virus is terrifying, but modern science and technology are also very powerful in the study of viruses, and one of the most effective means to deal with viruses is to develop corresponding antibody vaccines.

"This matter is going to be handed over to you, everyone wants to go to this living planet as soon as possible to play, tsk, this planet is completely opposite to some parts of our earth."

"We have an equator on the earth, and then the north and south poles and two cold zones, but this planet is just the opposite, because it has neither revolution nor autobiography, and the energy is obtained by two stars, so the place where the stars above AB shine directly form two hot poles, that is, cold spots similar to the north and south poles of the earth, but the planet is in the tropics."

"Then as the stellar light slowly changes from direct to bias, the temperature on the surface of the planet gradually decreases, temperate, cold, and it is extremely interesting that the cold zone on this planet is the same as the equator on our earth, which orbits the entire planet, rather than existing in the way of the north and south poles."

Tang Boyuan pointed to the simulated AB star on the monitor, a white round line around the whole planet, this is the cold zone on the planet, and then two red areas, these areas are the areas directly illuminated by the light of the stars, that is, the tropics on the planet, but there are two tropics.

"Two tropicals, one cold zone, just opposite to the earth?"

Luo Xiaoyao raised his eyebrows when he heard this.

"That's right, with this cold zone as the boundary, the whole planet can actually be the east and west hemispheres, the eastern hemisphere is irradiated by the light of star B, and the western hemisphere is irradiated by the light of star A, and above this cold zone line you can see two suns in the sky, and on this planet it is always day, no night."

Tang Boyuan nodded and said the very interesting part.

"And the life on the whole planet, because of the isolation of this cold zone is also very different, the eastern hemisphere is relatively close to star B, more affected, the temperature is relatively better, so the life on the eastern hemisphere is more prosperous, and the western hemisphere is farther away because of the light of A, so the climate in the western hemisphere is relatively colder, and the area of the cold 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 of rotation, the rotation cycle is about 360 years, in the long history of life evolution, the life on this planet has also developed a trend of following this change."

"So it will slowly move towards a pattern, from east to west, everyone look at this place, this small area connects the narrow corridor of the east and west hemispheres, and this area has animals migrating from east to west all the time."

"This may be a phenomenon on this planet that is really not conducive to our survival, because it means that we have to migrate every few hundred years, otherwise, you are now living in the tropics, and after a few hundred years, it will become a cold zone, I think this is why this planet is very suitable for the reproduction and development of life, but the important reason why the civilization here has always been relatively primitive, because it will be migrated on the entire planet every few hundred years, which greatly delays 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 civilization development here has always been in the stage of primitive civilization.

Time passed slowly, and the "Kyushu" spacecraft got closer and closer to AB Star, until it finally arrived at the outer space of AB Star and began to anchor here in outer space.

"Hurry, hurry!"

On the spacecraft, small anti-gravity spaceships in the shape of flying saucers are constantly taking off, and these spaceships are flying fast, flying into the atmosphere of AB star, heading straight to various locations on AB star, preparing to collect samples from all over the planet, especially the most important virus samples, because in order to develop a virus vaccine, it is necessary to study and analyze the virus.

In a vast grassland in the eastern hemisphere of AB star, the grassland is full of trees, grass grows and warblers fly, all kinds of animals live very leisurely on the grassland, the largest number of which is similar to the earth's cattle, sheep and other animals, the appearance does not look too different, but their reminders are far greater than the earth's side, any kind can also be compared to the big buffalo on the earth, and the large ones can be compared with the elephants on the earth.

Herds and mighty in the dense grass of the grassland, early grassland, large carnivores chase their prey, these carnivores are very large in size, far beyond the lion tigers on the earth, fast, agile, the bite force of the blood basin mouth is very strong, in the dense grassland comfortably chasing their prey.

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, wings spread more than ten meters, but like an airplane, the speed is fast gliding in the sky, a swoop and even directly attack all kinds of animals on the ground, even large predators are not afraid at all.

In the dense grass, a group of dwarf primitive natives with spears, stone axes, sticks and other weapons sneaked through the grass to approach their prey target, this time, their prey was a large buffalo-like animal like an African elephant, this buffalo was still leisurely eating grass, not noticing that it had become the prey of others.

“*&&…………”

Seeing that the time was ripe, the indigenous leader stood up and gave a loud command, and suddenly the natives who had already been surrounded on all sides instantly emerged, and the spears in their hands continued to fly out, forming a rain of spears and flying towards the already frightened buffalo-like animals.

Most of the spears were bounced off by the thick skin of the animals, and only a few were inserted, but they were not very deep, that is, some skin wounds, and the injured animals ran wildly with their hooves, and the natives did not dare to hit them even if they were in the front.

However, these natives also often hunt this animal to eat, so they are also prepared, some aborigines use long trees as tripping ropes, set traps in front of the buffalo run, the buffalo in the rapid running was tripped by the tree, and suddenly the bones on the legs were broken, and they could only crawl on the ground, and finally the aborigines slowly stabbed to death with spears.

The natives used stone axes, knives and other tools to cut the large animal apart, and then happily carried large pieces of meat back to their camp, where a group of children were already hungry for food.

There is no night or day on this planet, because the sun is in one position, so it is always day, back to the camp, soon the bonfire rises again, and the large, large pieces of meat are shelved, and the enticing aroma is emitted under the fire, and the primitive natives gather around and begin to sing and dance to celebrate the harvest.

Just when they were full of food and drink, they fell into a deep sleep and rest, 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 a group of earthlings wearing spacesuits and loaded guns walked out and went straight to the indigenous camp.

“**……&”

An alarm sounded, and the primitive natives in charge of the sentry finally found out, and he screamed loudly in panic, there was originally a fire, and beasts, animals, etc. did not dare to approach the camp, unless they were very hungry and dared to come and steal some food, but now these people who had never seen it before actually came straight to their camp, obviously with bad intentions.

Soon the natives were all 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, only to see these natives soon slowly fall, frightened the rest of the natives in panic and fled into the grass on all sides.

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