If the money is enough, Xu Ming also wants to buy a full-body protective clothing.

This will prevent direct exposure to unfamiliar environments and being affected by invisible damage such as harmful microorganisms and strong radiation in the air.

However, the price of professional sealed protective clothing costs at least four or five thousand yuan. If you buy it, you will soon become a pauper.

After thinking about it, I had to give up.

"Besides, rabbits can survive normally for more than two days, be healthy and lively, which means that there will be nothing wrong with humans when they are gone. Those extra worries are unnecessary. The radiation intensity has been measured with a radiometer, and at least the nearby radiation intensity is within a safe range."

All right.

Since you are poor, you can only take more risks.

The timids starve to death, the bold ones to death!

Xu Ming made up his mind to be at 8 pm on November 3rd.

He changed into a windbreaker, wore cut-proof gloves on his hands, hiking boots under his feet, and a filter mask with a pig's mouth structure on his face, pinning the domestic multi-purpose saber around his waist.

Then use your mind to control it, expand the diameter of the light-transmitting hole in the center of the mysterious vortex to the size of the millstone.

Due to the different atmospheric pressures on both sides.

Under the action of siphon, a strong wind suddenly appeared in the rented house of 15 square meters, and a large amount of air poured into the vortex of the small portal.

Fortunately, Xu Ming closed the window in advance, locked the door, pulled the curtains, and tried not to leave any gaps.

The lights in the room were also turned off.

In the dark room.

Only the mysterious vortex in front of me that emits white light is the only light source, illuminating the small area.

Accompanied by the whirring airflow.

Through the large channel of the millstone, Xu Ming stuffed his travel backpack, outdoor sleeping bag, windproof lighter, telescope, solar flashlight, compass, two boxes of mineral water, a large bag of convenience food, as well as gravity meter, radiometer, air component detector and other items.

But Xu Ming did not rush to go there.

Sitting beside the bed, he stared at the data changes of the barometer in his hand, and waited patiently for the air pressure in the room to lower it to the appropriate range.

"After measurement, the atmospheric pressure there is only 83% of that of Blue Star, which is equivalent to the mountain environment of Blue Star at an altitude of 1,500 and 600 meters. If you don't prepare, the air pressure in the body is greater than the air pressure outside the body. Even if you don't enter a vacuum environment and the blood boils and dies instantly, it will also have an impact on human health, such as being unable to inhale in a short period of time, tiny bubbles in the blood vessels, causing heart discomfort, etc."

Therefore, there must be a smooth transition process.

The method Xu Ming took was to close the doors and windows tightly, wait until the air in the room was absorbed to a strong and balanced pressure, and then go to the world after the vortex.

By the way, how could he know so much?

You should know that he only has the education of graduating from high school, and his academic performance is not very good at school.

How do you know so much?

This is mainly due to the contribution of the Internet era. He especially likes to watch some popular humanities videos, and has followed many up-and-comers in the technology and digital circles of B station, including "The Universe", "Survival in the Wild", "Man and Nature" and other series of documentary videos.

I usually read hundreds or thousands of books on the Internet, so I naturally know more.

More than twenty minutes later.

The data on the barometer is 0.889 (standard air pressure is 1).

Then it can't be lowered anymore. After all, this rental house is not completely sealed, and air outside will still seep in through the gap.

"Forget it, this value is almost enough, and the airflow is much smaller. The change in air pressure difference by a few percent will not have much impact on the human body."

Xu Ming no longer hesitates!

He stood up, fixed the mysterious vortex, then leaned forward, and stuck his head into the aperture.

Then the body trunk part.

Fortunately, the aperture diameter is more than half a meter, 1.72 meters tall and 120 meters weighs, Xu Ming easily put most of his body in.

Then he kicked hard under his feet and disappeared into the rental house.

...

After landing,

Xu Ming immediately felt lighter, as if he had lost dozens of kilograms of weight.

But breathing becomes a little difficult, exhaling out easily, but inhaling into the body is a little difficult.

He quickly walked to the mysterious vortex that was still following him, sucked the high-pressure and strong air flow coming from the rental house, and slowly narrowed the diameter of the vortex to adapt to the environment here.

More than ten minutes later.

Xu Ming finally got rid of the uneven air pressure on both sides and had the opportunity to observe this new world.

The blue sky above the head.

The stars hang like burning yellow diamonds in the sky, shining soft cross light.

Under your feet is a earth that is as green as oil and full of vitality.

The warm wind is gentle.

Huh ~

Take a deep breath.

The lungs are like a clear spring flowing through, nourishing every cell.

On the Blue Star, the air mixed with harmful particles such as car exhaust, pm2.5, industrial pollutants, etc. 24 hours a day was completely isolated and disappeared, and the atmosphere was transparent to an absolute transparency.

This made Xu Ming look at the scenery in the distance as if he had an anime perspective, and every corner was as clear as an oil painting.

"Fresh, the air here is so fresh, and there is a sweet smell!"

Xu Ming's words are not exaggerated. The dirty and smelly polluting air has been breathing for a long time, and suddenly comes to this new world. Even if the air is originally colorless and tasteless and has no smell, it will feel extremely sweet, with the fragrance of soil and plants.

Look around the surroundings.

Xu Ming found himself in a green grassland, his feet were very soft and slightly elastic, like a layer of green carpet laid on the ground.

The terrain of the foothold is relatively high and is located on the top of a hill.

He took out his compass to determine the four directions: southeast, west and north.

Take out a blank A2 paper and a 2b pencil from your backpack, and name the hill under your feet "Meadow Hill" and mark it in the center of the map.

Taking this as a reference point, Xu Ming drew some pictograms on the map as he saw through the telescope.

"In the east direction, there are forests within ten kilometers, with the crown height of about ten meters." Xu Ming drew a few small trees on the map to represent the forest.

"In the north direction, the terrain gradually rises, and the surface plants transition from forest to grassland." The word "not" similar to the inverted hand-in-hand represents the grassland.

"In the west direction, looking around, there are all tall trees, with a height of more than 100 meters, covering the sky and the sun, and the sight cannot pass through. They are temporarily considered as forests."

"In the south direction, there is a river flowing from north to south, with a large runoff. Except for the impact of the riverbanks on both sides, the rest are forests."

That is to say,

The hill at Xu Ming's feet is surrounded by forests, and there are only mountains in the north that can see some grassland landforms.

After roughly observing the surrounding environment and making map notes.

Xu Ming used those physical measurement equipment to quickly measure several important parameters about this world:

Gravity acceleration: 6.82m/s^2 (only 70% of Blue Star)

Atmospheric pressure: 0.083mpa (only 82% of Blue Star)

Air oxygen content: 28%

Nitrogen content: 70%

Carbon dioxide content: 0 (it is difficult to measure accurately below 0.01%)

Natural radiation intensity: 1.45msv/year (only 60% of Blue Star)

Temperature: 22c

All measurement items are over.

Xu Ming jumped up with force and easily jumped to more than one meter high.

After landing, he excitedly said: "No wonder he felt that it was dozens of kilograms lighter. Except for the gravity coefficient, the atmospheric pressure in this world is obviously smaller than that of the Blue Star. The other differences are basically not big, or the impact can be ignored... Ordinary humans can survive here normally!"

"The plant resources here are so rich and the area is so vast, and there is no sign of development. It can be said that it is another vitality blue star!"
