Several people who dived this time, Yang Hua, Wang Lei often dived.

On this steel dragging boat, he had dived, and Li Xuan was very relieved to the two of him.

But Qin Bin, from his come to the steel dragging boat to this day, this is the first time he has participated in underwater operations.

Qin Bin's high school results are not ideal.

I went to the shipyard as a apprenticeship before I finished my middle school.

According to Li Xuan, although he stayed on the sea all the year round, he also stayed on the ship all year round and almost did not contact the sea.

Therefore, after Li Xuan went to the sea, he paid special attention to Qin Bin.

But soon, Li Xuan discovered that his worry was superfluous.

After all, Qin Bin also grew up in the fishing village, and he had been eating at sea than Li Xuan.

He is very good in water, and he is curious about everything on the sea floor.

The seawater in this sea is not clear. Although the offshore is far away, the seawater has been contaminated to a certain extent. It seems that there are some gray and black.

This is the normal state of the ocean in most places now.

While the rich resources of the ocean are developed and utilized, they are also severely polluted because of the lack of protection of protection.

There is no trace of polluted ocean, which looks beautiful blue, and the taste of the sea is slightly salty. Under the seawater, there are a lot of healthy and beautiful marine animals.

For more than a century, human beings have continued to obtain marine resources, and most of the oceans around the world have been damaged by different degrees of environment.

Like Yulong Bay, there are almost no industries along the coast, there are really not many.

However, the surrounding seawater is not deep, only tens of meters.

Most of the trained divers, wearing the most common diving clothes, can dive to this depth.

Li Xuan's diving suit wears most of the dive clothes on the overshide of the overshide. After this depth, in addition to feeling that the ears are somewhat different, it seems that there are some earwax in the ears that are constantly falling off. Occasionally, everyone makes a sound. Everyone

No discomfort.

On such a deep sea, the sun is no longer so dazzling.

The sun shot directly into the sea, and the light looked green.

A large number of marine plants are covered with the entire sea.

Among them, there was a seaweed that shocked Wang Lei and Qin Bin.

Seaweed refers to the multi -cell algae plants that can be seen in the naked eye growing in the sea. There are many types. There are more than 100 edible seaweed in the world. There are common kelp in life, skirt vegetables and seaweed.

But those seaweed, compared with the seaweed seen in front of you, the visual effect is really too far away.

I saw the seaweed, the appearance was a bit like a inverted pagoda sugar, which was very huge in size. It was as high as three or four floors. Looking at it from a distance, it was really like a floating island in the cartoon.

Gifted

Li Xuan knew it at a glance. This is a kind of brown algae, named giant algae, the longest in the algae kingdom. Most giant algae can grow to tens of meters high.

100 meters, fix the algae on the reef by the fixing device.

The giant algae I saw now is only three or four floors, and it is really small in the giant algae.

Li Xuanyou took a closer look at it and found that it was a trunk in the center. There were dozens of small branches like small branches. There were small leaves on the handle. Some leaves were nearly half meters long.

Width.

Li Xuan knows that the reason why this giant algae can grow upward looks like floating on the bottom of the sea. That is because its blades have airbags, and the airbags can produce enough buoyancy

Raise it.

In front of a huge algae leaf, Li Xuanyou took a closer look and saw that those airbags were visible to the naked eye on both sides of the main leaves on the leaves.

This giant algae grows very lush, and the huge leaves are layered in layers of sea water.

Li Xuan couldn't help but sigh, it can be described as a grass, which can become a forest.

This kind of scene is almost unimaginable on land, but on the bottom of the sea, it can be seen everywhere.

But just after a while, Li Xuan was not interested in continuing to look down.

The huge algae can be so large, which originated from its rapid growth rate. Its daily growth rate can reach half a meter. It can grow up to 50 meters a year. It is one of the fastest growing creatures in the world and its life span

It is also 12 years, and it is not surprising that it grows at this growth rate. It is not surprising.

But this giant algae has grown to the limit of its growth, and it will never grow up.

Li Xuan knows very much about giant algae.

The giant algae is a type of cold water. It likes to grow on the underwater rock with deep water, and vertically distributed on the low tide line.

In the shallow sea in eastern Pacific and near the Oceania, giant algae form a magnificent "underwater forest" on the bottom of the sea. Those "underwater deep forests" provide inhabiting and breeding places for various marine creatures.

Strictly speaking, it is considered to be a subtropical ocean. Although this giant algae can grow out of the sea floor in this sea area, it is impossible to grow up due to the environment.

In the eyes of humans, it is a behemoth.

But in the same kind of algae, it is a small bean.

Only at the bottom of the relatively dark deep sea can we grow a very strong giant giant algae.

Seeing Qin Bin and Wang Lei still watched this giant algae and didn't want to leave, Li Xuan couldn't help but pushed them.

This trip is to search for fishing, but it is not from the sightseeing.

Although such huge algae are in the fields of chemicals, energy, medicine and other fields, are important raw materials. 80%of giant algae are moisture, and the rest contain potassium and iodine. Therefore, a variety of chemical raw materials can be extracted.

Crush the plants of giant algae and add microbial fermentation for a few days, and can produce 4,000 cubic meters of combustible gas per 1,000 tons of raw materials, with a conversion rate of more than 80%.

Alcohol, acetone, etc.

However, Li Xuan's fishing boat is not as large as this giant algae. Even if they think of a way, pull this giant algae to the sea, it is impossible to bring it back.

No beneficial.

After Li Xuanyi reminded, Wang Lei and Qin Bin smiled embarrassedly, and quickly spread out, and went to the bottom of the sea to search carefully.

而另一边,可能是以前见过巨藻,所以对巨藻见怪不怪的杨华,根本就没有多看这株巨藻一眼,此刻他正在海底,跟一条外表酷似多宝鱼,但比多

Treasure fish is much more fierce and ugly.
