No one understands the situation on the seabed better than Yan Qingcheng, because she is responsible for the port reconstruction project, and she knows how many gullies there are on the seabed, so she asked Director Cao to find an ace diver to locate the cargo box on the seabed.

What level of divers in her own group salvage team, she herself knows very well.

Director Cao underestimated this matter, and then he began to get anxious.

The divers of the salvage team appeared on the surface several times, and the result was to shake their heads.

Yan Qingcheng was anxious, and a director comforted: "Mr. Yan, don't worry, nano silica is a material that is insoluble in water and will not be destroyed by water, and it is wrapped in a sealed box, so it makes no difference if you fish it out early or later." ”

Hearing this, Yan Qingcheng sneered: "I said, this shipment is not nano silica, this is a composite silica nano sheet imported from Dongying, who told you that it is insoluble in water?"

The director said embarrassedly: "I looked it up on the Internet before." ”

Yan Qingcheng sneered again: "Nano silica is insoluble in water, but this is not the case with composite silica nanosheets, it can be easily dissolved in water, and it reacts freely in water and assembles into structure-fluid, a very active structural fluid!"

"Besides, what if it has a sealed box to wrap it? The sealed box is waterproof and fireproof, but it is not protected against high water pressure! How long can it last at such a deep seabed? Once the sealed box is damaged by water pressure, this batch of goods will be completely finished!"

Listening to the introduction, Ao Muyang subconsciously asked, "Is this kind of composite silica nanosheet very expensive?"

Yan Qingcheng didn't get angry in the face of him, but sighed lightly and said: "The price is not expensive, one kilogram is only about 10,000 US dollars, but this kind of laboratory chemicals is a controlled material, and it is difficult to pass the customs. ”

Ao Muyang nodded silently, and then checked the Internet himself.

He didn't find a composite silica nanosheet, but he did find a nano-silica, which is exactly what its name suggests, a specially purified silica, very small in size, in the nanometer range.

Like many nanomaterials, it has small size effect, surface interface effect, quantum size effect and macroscopic quantum channel effect, has special photoelectric characteristics, high magnetoresistance, nonlinear resistance, and at high temperatures, it still has high strength, high toughness, good stability and other singularities, which plays an important role in many fields.

In the introduction, there is a paragraph that emphasizes that the research of nanomaterials in China has achieved many results, but the research of nano-silica has just started, and it is the focus of domestic materials chemistry research.

After reading these introductions, Ao Muyang probably understands that this thing should not be a rare item, but China cannot produce it freely, so foreign countries strictly control the market situation of Chinese manufactured goods that are rare and expensive.

Yan Qingcheng was very anxious to check his watch again and again, Director Cao made several phone calls, and said with a depressed face: "There is a traffic jam in the city, they are blocked!"

Hearing this, Yan Qingcheng almost kicked this Director Cao into the water.

Since people contacted capable and excellent divers, Ao Muyang didn't want to interfere in many things, but now seeing that the divers were late, Yan Qingcheng couldn't wait, so he decided to volunteer.

Putting down the coffee cup, he said, "Mr. Yan, your coffee is very fragrant and delicious." ”

Yan Qingcheng reluctantly smiled and said, "If you like it, if you want to refill the cup, you can say it." ”

Ao Muyang said: "Help me refill a drink, I will warm up later, and help me find a set of diving suits, and I will help you go underwater positioning." ”

Hearing this, everyone looked at him in surprise.

Ao Muyang said with a smile: "Don't hide it, I'm a diver, and to put it mildly, my diving skills should be the number one in the entire Red Ocean platoon." ”

He said this quite politely, in fact, his diving skills are the best in the world!

Yan Qingcheng hesitated: "Is it? But this ......"

Ao Muyang said: "Give me a set of diving suits, I should be able to help with this favor, I hope that Mr. Yan can also do me a favor when I buy a fishing boat." ”

Yan Qingcheng was overjoyed and said, "Whether Mr. Ao can help us determine the location of the cargo box, I will remember your favor." ”

A set of diving suits was brought up, this is a very modern diving suit, like a spacesuit, all white, very heavy, the hood is transparent in all directions, and there is a small computer screen on the arm.

He put on a diving suit, and someone put a couple of small palm-sized machines in his fanny bag, explaining, "This is a laser emitter, if you find the cargo box and attach it to it, we can salvage it." ”

Ao Muyang nodded, and then fell into the water in a back-to-back position.

In offshore areas, the sea water is turbid, especially in this kind of port area, because there are many ships coming and going and sewage pipes directly enter the sea, the sea water is even more polluted, and there is almost no visibility at all.

Ao Muyang's vision was also obstructed, his eyes were not affected by the light in the water, but they were affected by these pollutants, and his vision was all a dull yellow.

Seeing this, Ao Muyang sighed helplessly, where is the blue ocean?

Suddenly, he had a big wish in his heart, if one day his financial resources and ability were enough, he wanted to deal with the problem of marine pollution.

Of course, he can't control just the ocean of his homeland, and the entire global sea.

The water pressure was nothing to him, and he sped down as soon as he got into the water.

The ocean was deep, and at the end of the day, he saw a rocky bottom of the sea.

When he got to the bottom of the sea, his vision was a little better, there was a lot of garbage on the bottom of the sea, but there were not many liquid pollutants, because of gravity and buoyancy, this kind of pollutants were in the upper waters.

The divers of the Blue Boat Crew had already returned, leaving him alone in this silent world.

Yes, the bottom of the sea here is quiet, like a cemetery.

There is no life, no fish, shrimp and crabs, no seaweeds, and probably not even the most common plankton in the ocean.

Maybe there were many ships sailing on the sea, but Ao Muyang looked up, and his vision was so poor that he couldn't see anything.

This is not the time to be nostalgic for the past and the present, Ao Muyang stomped on the bottom of the sea and refloated, swimming quickly in the water to scan the bottom of the sea.

For others, finding something in the depths of the dark ocean can be a thrill and an adventure. But for Ao Muyang, this matter is very routine and ordinary.

He once helped Su Jinnan find the gun that fell to the bottom of the sea, except for the difference in water depth, the other processes are the same.

After swimming rapidly at the bottom of the sea for more than ten minutes, the first box appeared in his field of vision.

This is a box about the size of a freezer, sunk in an artificial trench, Ao Muyang saw it and understood the reason why Yan Qingcheng was so anxious.

Judging from the size of the box, there are a lot of composite silica nanosheets that can be loaded inside!

He attached a laser marker to the box, and then went to look for other boxes, according to Yan Qingcheng, there were a total of six boxes that fell into the water.
