After throwing away the oxygen mask in his hand and adapting to the environment here, Tianming took a deep breath of air in a small space, and his lungs were as if they were watered with water, which was extremely refreshing.

Standing at the highest point of the hillside and looking around for a week, Tianming said happily: "To commemorate this historic moment, the mountain will be called 'landing mountain' in the future."

I greedily breathed the air here and lay on the green grass as green as oil. I have never seen this kind of grass on the grass before. The leaves are big and soft, as if I were lying on a carpet, densely packed, and the grass grows very thick and evenly. When I lie on it, I feel more comfortable than the big bed at home. Tianming has the urge to sleep on it for 3 days.

Tianming gave this grass that you have never seen before a simple name: "Sleep Grass", which means that you can fall asleep quickly when you lie on it.

I originally wanted to stay in the small space for a while, but my superpower space of less than 1 cubic meter is filled with tool supplies, as well as a few packs of biscuits and 2 bottles of drinks.

More than ten hours passed, and Tianming walked around the neighboring landing mountain, familiarizing himself with the terrain and didn't go far.

In fact, Tianming estimated that the land area inside the small space was not very large.

The length, width and height of the small space are 12 kilometers, and are in the barrier of a regular cube.

According to popular sayings, this barrier can also be called "space barrier". Under the isolation of space barriers, the small space continent consists of an 8Km crust layer and a 4Km atmosphere to form a closed ecosystem.

The land area of ​​12×12 equals 144 square kilometers is not all useful, and a large shadow area has been found in the sky dark.

The reason why there are shadow areas is that the characteristics of small spaces have to be explained below.

First, small space exists on the surface of a huge terrestrial planet, but is independent of this planet.

According to the parallel space theory, the existence of overlapping space is possible. Tianming guessed that a small space is the overlapping solidification phenomenon caused by the collision between the earth's plane and the mysterious plane. It can adapt to the rules of the two planes and can also isolate the matter in the two spaces, so that Tianming saw that a huge and smooth mirror cliff was cut by the small space on this earth-like planet.

The height of the cliff is more than 20,000 meters. Due to the shooting angle of nearly 30 degrees, the light shining from the orange-red star in the center of this galaxy is blocked by 1/3 of this cliff wall. That is to say, the area that accounts for 1/3 of the 46 square kilometers of small space is shrouded in the shadow of the cliff wall and is trapped in permanent darkness.

Thankfully, this planet is not autobiographical, and another 2-3 places can enjoy permanent daytime and light.

But it is not necessarily correct to draw a conclusion like this. There is darkness in small spaces. There is a huge gray-white meteorite belt around this planet. Every once in a while, the meteorite belt will pass over the small space and block the light from the stars.

After eating all the biscuits and drinks, Tianming observed in a small space for nearly 30 hours, and finally made an intuitive discovery about the change of day and night: about 22 hours during the day and 4 hours during the night.

The dark night here is the shading time of the solar eclipse.
