Chen Rui said, "This military ID card is the only thing that can prove the identity of this corpse, together with his relics and ashes, when it returns to the surface, I will hand it over to the German government and government, so that the German government and government can find his family, inform him of the news, and return his relics and ashes to his family." ”――

Chen Rui is in the Inner Earth and has two tasks, 1, to explore the Inner Earth. 2. Collect samples of biological species, hydrology, climate, natural resources, etc. in the inner world to inform, and determine whether the inner world can become a new ideal home for human beings.

Chen Rui camped at the lakeside and stayed there for five days.

During the five days, Chen Rui explored the entire lake and circled around the shore, collecting samples and information about biological species, hydrology, climate, and natural resources around the lake.

In Chen Rui's species bank and natural resources bank, 179 species of wild animals and fish have been discovered, 271 species of plants have been newly discovered, 14 species of microorganisms have been added, and 11 species of fungi and other organisms have been added.

Chen Rui turned on the live broadcast camera and said in front of the camera, "Nature has various ecosystems, tropical rainforests, savannahs, deserts, wetlands, oceans, rivers, even if it is a small pond, it is a complex ecosystem.

In the inorganic environment, through the 'invisible hand' of nature, ecological regulation constitutes a balanced, circulating, and constantly regulated unified overall ecosystem.

At the surface, the largest ecosystem on Earth is the biosphere, and the most complex ecosystem is the tropical rainforest ecosystem. Humans mainly live in artificial ecosystems, mainly in cities and farmland.

underground. The entire inner world is a balanced, circular, unified, and closed ecosystem, and the geocentric sun is like an engine, continuously providing energy for life activities in the inner world.

The lake, and the natural environment around it, is a circulating ecosystem.

Trees in the jungle around the lake, bushes. Surface vegetation, fungi, and aquatic plants near the lake, aquatic plants in the lake synthesize inorganic matter into organic matter through photosynthesis, and are the 'producers' in the ecosystem, providing food for 'consumers' and a source of organic matter.

The herbivores, insects, and herbivorous fish that live around the lake depend on plants and become 'primary consumers'. There are also 'secondary consumers' above the primary consumers, who live on herbivores. Finally, there is a tertiary consumer above the secondary consumer, who preys on small carnivores, at the top of the food chain.

The most important link in the lake ecosystem, the decomposers, are mainly microorganisms, microorganisms in the soil, and microorganisms in the lake, which decompose organic matter into inorganic matter.

Plants take in energy from the inorganic environment, synthesize organic matter, after the producer is swallowed by the primary consumer, the energy will be transmitted to the primary consumer, the primary consumer is preyed, and then the energy will be transferred to the secondary, tertiary, and finally, when the organic life dies, the microorganisms that play the role of decomposer will decompose them into inorganic matter, and return the source from the environment to the environment.

Inorganic matter - (energy) - organic matter - (energy) - inorganic matter, this is a complete cycle.

Energy is the foundation of life.

Life is a cyclical process.

Biologists and naturalists all over the world are of great interest to the ecosystems of the inner world.

The lush forests, fertile soil, temperate climate, dense rivers, lakes, and a large amount of information collected by Chen Rui about the inner world in Chen Rui's real-time live broadcast have made countries around the world look forward to it more and more.

The inner world, the new home of mankind, has become the consensus of more and more people.

After staying by the lake for five days, Chen Rui left the lake and continued to set off.

While live broadcasting, the mobile phone APP was used to scan the newly discovered biological species on the way, collect specimens, and record data information.

On a hill, Chen Rui picked up a black object from the ground and said in front of the camera, "This is a piece of coal, and under my feet is an open-pit coal mine."

The discovery of this open-pit coal mine illustrates the fact that hundreds of millions of years ago, this was a world of unusually lush vegetation.

Because the process of coal formation is a long period of hundreds of millions of years, a large number of plant debris after complex biochemical, geochemical, physical and chemical processes, transformed into coal, the formation of coal at least tens of millions, hundreds of millions of years. ”

There is coal and there is definitely oil, coal is formed from plant remains, and oil is formed from animal remains, animal fats and proteins are gradually liquefied to form oil.

Coal and oil can provide energy for the humans living in the Inner World in the future. ”

Chen Rui made a mark on the map of his phone where he is now, collected some samples of coal, and then left the coal mine.

Chen Rui continued to set off along the river.

Chen Rui said, "The river is to this vast and vast land, just like the blood vessels are to the human body, the river water nourishes the land on both sides of the river, and through the small river can reach the wider river, most of the creatures live by the river and in the jungle on both sides of the river."

Because, plants need water to irrigate, moisturize, animals need to drink water, get rich food from the river, hunt other animals that come to the river to drink water, especially when the weather is hot and the land is dry, the river is related to their survival, and an unusually large and prosperous natural ecosystem has been formed around the river.

If I want to collect information about the species of creatures in the inner world, the best way to do that is to follow the river.

Moreover, most of the ancient civilizations on the earth lived in river basins, because rivers not only provide drinking water and living water necessary for human survival, but also rich fish food can be obtained in rivers, rivers irrigate the land along both banks of the river, so that the land is fertile, and human beings cultivate on the fertile land, obtain sufficient food, and settle down.

For example, the ancient Chinese originated in the Yellow River Valley, the ancient Egyptians originated in the Nile Valley, the ancient Indians originated in the Ganges River Valley, and the ancient Babylonians originated in the two river basins.

So, I'm going to go upstream along the river.

This vast and vast land is not like the surface, after thousands of years of human development, the degree of development is very large, and the vegetation on the surface has been seriously damaged.

The land is unexplored, and most of the area is dense primeval jungle, with tall towering trees, and rainforests that are more extensive than the Amazon rainforest.

Chen Rui walked along the river through the dense jungle.

In fact, Chen Rui has a faster way, flying in the sky, in less than a day, he can follow the river, from the source of the river to the outlet of the river, the ocean, as long as a few days, you can draw a detailed map of the inner world.

However, this doesn't make any sense to explore the Inner World.

In order to explore the inner world, collect information on the biological species, hydrology, climate, natural resources, minerals and other information on this land, and discover the relics left by the geocentric civilization that once lived on this land, Chen Rui chose to walk along the river through the dense jungle.

And, for a true adventurer, it's the joy of discovery, exploring magical worlds, discovering the wonders and mysteries of this world.

For the more than 500 million viewers around the world who are watching Chen Rui's live broadcast, the live broadcast of exploring the inner world is magical.

Watching Chen Rui use the mobile app to discover new biological species, make specimens of newly discovered biological species, and record the detailed information of biological species, it is full of amazement.

In the live video screen, Chen Rui's continuous discovery also shocked them, 300 kilograms of giant doghead gold, super gold mine, corn cobs in the inner world, the bones of Nazi officers, and, now, the giant forest in front of Chen Rui.

"In front of me was a huge forest, towering and juggling into the clouds, and I felt as if I had come to the land of the giant tree, and standing under the giant tree, I felt very small, like I was walking in front of a building, and I needed to look up at it." Chen Rui said.

The towering giant tree is towering and straight into the clouds, the huge trunk needs dozens of people to be able to hold it, the first branch of the giant tree alone is more than 2 meters in diameter, larger than a big banyan tree in Chen Rui's hometown, and several trucks can run in parallel on the trunk of the giant tree, which can really be called a tree of the towering giant tree.

Audiences all over the world were also shocked, and the giant trees were towering! Straight into the clouds.

Chen Rui counted it, and there were 47 giant trees in the giant forest.

Giant trees are classified according to the type of trees, and they are considered to be cedar genus.

Chen Rui found the largest cedar tree in the giant sequoia forest, "Is there a bigger tree on earth than this tree, and is there a !! ”

Definitely not!!

Chen Rui took out a cloth ruler and measured the giant sequoia tree, and then said, "The circumference of the tree is 57.7 meters, which is 40 meters above the ground."

A branch, 3.1 meters in diameter, 247.4 meters high, what is this concept, 57.7 meters of tree circumference needs 50 people to be able to hold it, 247.4 meters of tree height, equivalent to the 'stratosphere giant', is more than 5 times the statue of the goddess without adding the pedestal, equivalent to a 70-story building, higher than 3 'Dinghai International Hotel'.
