Below 1000 meters, the operating range of professional deep submersibles is possible.

1500+ meters is already a deep sea, and the color of the sea is pitch black. At this depth, there are no large creatures such as whales and sharks.

Chen Rui dived to the bottom of the sea.

The sea is not deep, about 3 or 40 meters.

The light is very strong, the sea water is very clear, and the bottom of the sea is bright.

The landscape of tropical coral reefs under the sea is no worse than that on land.

The plants on the seabed are rich and colorful, and their colors are also diverse, including purple, green, and brown, and in terms of morphology, morphology, morphology, and ecological characteristics.

In terms of species, there are also many kinds, among which the most common species are seaweed, chicken hairy algae, licholilycliflower, red hairy algae, sea soa, partridge and so on.

In addition to plants, the animals are also very peculiar, with colorful tropical marine fish swimming around.

Flounder swims sideways in the sea like falling leaves fluttering in the wind.

Sea urchins inhabit the reef forests or stone crevices in the seaweed-rich sea area, wearing brown needles and felt, strange shapes, and when encountering foreign enemies, they desperately drill into the reef forests and stone crevices.

Sea turtles swim gracefully.

Sea cucumbers crawl on the stretch of their muscles and can only advance four meters per hour.

Squid and octopuses can suddenly spray water in front of them, using the reverse thrust of the water to quickly retreat

It is a colorful world in the sea, refracted by the sun's rays, colorful and colorful.

At this time, a sea snake swam past Chen Rui.

The sea snake is nearly 1 meter long, with a narrow head, a long snout, a black back, a distinctly yellow belly, and a yellow spot on the tail.

Chen Rui recognized this as a long-snouted sea snake, which is distributed in all tropical waters in the world, and is highly venomous, and can secrete neurotoxins, which is enough to be fatal.

In fact, most of the species of sea snakes that survive in the sea are highly venomous, far more poisonous than those on land.

Although, the long-snouted sea snake posed no threat to Chen Rui.

But Chen Rui was still cautious not to provoke it.

Chen Rui stood still at the bottom of the sea, waiting for the sea snake to swim by.

Waiting for the sea snake to gradually move away, Chen Rui continued to move forward.

Walking on the ocean floor.

Along the way, Chen Rui found many kinds of sea treasures at the bottom of the sea.

For example, not far from Chen Rui, a sea cucumber lying quietly on the reef is like a cucumber, dressed in a brown coat, and the back of its body is covered with large and small cone-shaped meat thorns.

Although sea cucumbers are like big bugs, they look a bit disgusting.

However, it is a very precious treasure in the sea, not only a delicacy on the table, but also a nutritional tonic, which has a good effect on enhancing physical fitness, preventing diseases and prolonging life.

It is called the 'ginseng' of the sea.

There is a saying that the most replenished in the mountains is 'ginseng', and the most replenished in the sea is 'sea cucumber'.

Chen Rui caught a few sea cucumbers and put them into the pregnant sea pearl space.

In addition to sea cucumbers, large lobsters and sea crabs were also caught.

The big lobster is very large, weighing several catties, and one is enough for Chen Rui to eat his fill.

The ocean is a treasure trove for mankind, and it is true.

The ocean is rich in biological resources.

Edible aquatic resources can be developed more than 3 billion tons per year without destroying the ecological balance.

There are a qiē mineral resources on land, and there are all under the great seabed.

The seabed alone contains enough copper ore for 6,000 years, nickel for 150,000 years, and aluminum for 20,000 years.

If all the salt contained in the ocean can be extracted and spread on the land, the ground will increase by nearly 100 meters.

There are also current energy, wave energy, and seawater temperature difference energy, which is "blue coal sea" by people.

Chen Rui continued to walk under the sea.

Suddenly, Chen Rui stumbled.

Chen Rui was stunned by something.

Chen Rui looked back and saw that it was a rock.

The rocks are soft.

Chen Rui kicked off a rock about the size of a pot lid from the rock.

A detached face is exposed on the rock.

When Chen Rui turned his head, he unconsciously swept the falling surface of the rock with the peripheral light of his eyes.

This look immediately shocked Chen Rui.

"It's a sea lily fossil." Chen Rui exclaimed in surprise, walked forward quickly, squatted down, wiped the sand and gravel from the rock, and examined it carefully.

Chen Rui saw that on the falling surface of the rock, some exquisite patterns appeared, with roots, stems, and crowns, the stems were ring-shaped, of different lengths, up to several meters long, and the shape of the patterns resembled a natural lily, lifelike.

Chen Rui once saw a sea lily fossil in the Yanjing Natural Land Museum, which is very similar to the pattern on the surface of the rock falling off in front of him.

Chen Rui can be sure that the pattern on the falling surface of the rock in front of him is the 'sea lily fossil'.

Many people see the name 'sea lily' and think it is a plant.

In fact, sea lily is a kind of echinoderm, and sea cucumber, sea urchin, etc., grew 450 million years ago, 200 million years earlier than the age of dinosaurs, is the earliest creature in history, but because the shape resembles a blooming lily, in addition to open buds, there are straight rhizomes, therefore, it was given a very apt name - sea lily.

These sea lily fossils are very valuable.

With very high scientific research value and archaeological value, people can see the internal structure of the sea lily, which provides extremely valuable information for the study of the evolution of the sea lily, truly reproduces the vicissitudes of evolution in nature, and outlines the wonderful landscape of the prehistoric ocean and marine life.

Its artistic value is also not low.

Sea lilies are extremely demanding on the environment in which they live, and it is extremely rare and precious to be able to become a complete fossil.

It is a national treasure.

In 06, a sea lily fossil with a length of 2 meters and a width of 1.2 meters reached a transfer price of 12 million.

A 3.2-meter-high, 2.6-meter-wide sea lily fossil in the Canton and East Museums is regarded as the treasure of the museum, and its value reaches 80 million yuan.

Chen Ruiyan was included in the pregnant sea pearl space.

Chen Rui also entered the pregnant Haizhu space.

Take a closer look at the sea lily fossils on the rocks.

Carefully peel away the rock formations.

What he saw shocked Chen Rui even more.

The sea lily fossil Chen Rui saw was not one, but a piece.

Chen Rui counted it, and there were 17 numbers.

Each one is clearly characterized, well preserved, the flowers are large, and the crystals are very bright.

The total area reaches hundreds of square meters, which is the largest in the world.

These fossil patterns of sea lilies appear on the rocks, lifelike, just like the lilies painted by the masters of Chinese painting, delicate and blooming.

"It's a work of art." Chen Rui said with some indignation.

Looking at these sea lily fossils, Chen Rui guessed in his heart.

About 200 to 300 million years ago, the climate of this sea area was warm, the sea water was blue and crystal clear, and beautiful sea lilies grew everywhere, because there were no natural predators, the number of organisms increased, and the remains of sea lilies and animals were constantly buried by sediment and deposited on the seabed, becoming precious fossils.
