My system is not decent

At any time, the professionalism of the tomb robbers should not be overestimated.

Of course, they also do better. For example, at sea now, those tomb robbers are more professional because each of their ships has diving equipment.

Not far from the sea is where the shipwreck is located.

In this shipwreck waters, the day Chen Wenzhe saw the most was actually 25 fishing boats rushing around, circling left and right, busy to and fro.

The scene at that time was very chaotic, as chaotic as a naval battle.

There are diving equipment on the fishing boats, and there are buoys floating on the sea surface for positioning.

It can be said that as long as the fishing boats come over, they are already "fished by all the people".

Some of these people come from professional salvage companies, while others are tourist diving instructors in the nature of "fanciers".

There are even a few Lao Haizai who live on fishing for abalone and sea cucumbers in the fishing grounds.

Due to the high cost, the fishermen each formed a temporary "Daobao joint-stock company".

The cost of piracy is borne by multiple fishermen in the form of a joint-stock system, and the proceeds are shared in proportion.

During the two days when the wind was at its peak, the peaceful island in the past was like the legendary Golden Island.

The pirates are in high spirits, and all kinds of fishing boats shuttle back and forth day and night.

Cultural relics began to be salvaged on a large scale, and countless damaged and discarded.

From time to time, cultural relic dealers come to the island to buy porcelain at prices ranging from hundreds to 1000 yuan.

In the past few years, a similar situation happened during the excavation of the shipwreck of the Yuan Dynasty in the "Sandaogang in Northeast China".

However, under the ban of relevant departments at that time, the fishermen's piracy was quickly curbed.

This time it is very different. With the development of information dissemination and the smooth flow of the folk cultural relics market, the local fishermen have a clear idea of ​​what they will harvest.

No way, it can only be said that times have changed.

You must know that decades ago, when some old fishermen salvaged underwater porcelain, they all returned directly to the sea.

Now it's all for profit, as long as there is money to make, what things can't be done?

Man made money and birds died for food. The reason why this ship can still leave some things is because of the law enforcement agencies of several local countries.

Although they grabbed the big head, they also made a little contribution to the sunken ship.

At least with their presence, many casualties have been avoided.

In the process of stealing treasure ships, especially at night, there are many cases of divers drowning late at night due to failure of oxygen supply equipment.

Most of these divers use dangerous air pump oxygen equipment to prolong their stay underwater.

This method is as old as 1848 when humans first conducted underwater archaeology.

At that time, in order to search for the relics of the inhabitants in the Swiss lake, the curator of the Lausanne museum was on a small boat, using a manual compressor to supply air to the divers.

And those fishermen, what good equipment do they have?

Some people's equipment is not even as good as that of the ancients one or two hundred years ago!

In the waters of underwater shipwrecks, not only vicious incidents of overt robbery, undercover robbery, and illegal armed robbery have occurred, but what is more, there has been a phenomenon of fishing boats from a country raising funds to participate in piracy.

This kind of chaos didn't stop until the waters of the wreck were controlled by law enforcement ships from various countries and the divers of the pirates were driven away.

After that, things were simple. After the salvage by the national law enforcement personnel, the underwater sunken ship became bare and nothing could be seen.

Later, it was used by others as a fake treasure ship to deceive people.

Of course, during the period, put some porcelain by the way, counterfeiting hailao porcelain.

It is also lucky to find those members of the Kangxi blue and white market. They did not enter the sunken ship, and they did not even search near the sunken ship.

After all, it was not the first time they had done something like salvage a sunken ship, and they already had a lot of experience.

After they got into the water, they didn't board the boat immediately, but measured and plotted around.

Afterwards, based on calculations, they specifically searched for places with thick silt and excavated. Unexpectedly, they really found something.

"Boss, these porcelains are preserved in large wooden boxes, and these large boxes are buried in the sand under a trench."

"I found it from under a coral reef. The coral reefs here are very scattered. Among the intervals of some coral reefs, some were filled with sand. When I dug, I found a big box."

"The situation is similar. The ship was half capsized and the cabin was broken. A lot of cargo should have been thrown out of the cabin."

"Stop talking nonsense. Now that you have found something, let's all go into the water. You must know that there are fishing grounds everywhere around this sea area, and it is easy to be discovered."

In fact, Gao Qijing didn't say anything, everyone knew that their actions could not be kept secret for two days.

Now that he found out, Gao Qijing made a decisive decision and sent people into the water again.

Underwater salvage, or underwater archaeology, is not easy.

First of all, the buoys to be left on the surface of the water, the team members followed the buoys and dived directly to the vicinity of the sunken ship.

The GPS position was determined and the first underwater photography was carried out.

Conduct preliminary underwater surveys and start counting porcelain.

Of course, under the water here, all you can see are broken porcelain pieces, and it is not easy to find a complete vessel.

Besides, there is no difference in essence between the excavation of underwater ruins and the excavation of field ruins.

The first period of time at the beginning must be used for treasure hunting.

That is, for surveys, i.e. positioning, measuring, photographing and videography, etc.

After entering the water, come to the side of the sunken ship, first use an iron rake to hook it on the side of the sunken ship.

Then use the lead drop buoy brought down, and then follow the safety rules and go into the water in pairs along the water entry rope under the buoy.

As far as the work process is concerned, underwater excavation is like an elegant and interesting game of building blocks, if you don't have to compete with other poachers for time and space.

In the first half of the day, the diving captain led the team to set up a baseline for marking the position above the sunken ship.

Then follow the direction of true north and south, use stainless steel pipes or ropes to set up a 20 cm x 20 cm "exploration square".

That is, the cells used to excavate porcelain are marked with red tape every 20 cm for underwater identification.

This is their underwater Rubik's Cube. At this stage, the team members should try to maintain the original appearance of the underwater ruins, but the original appearance is long gone.

As early as the first time they went into the water, they discovered that the underwater situation was really horrible.

At the bottom of the water, broken porcelain is scattered everywhere, and every fracture is shining with a new white light.

This is just a recent damage. There is a place on the west side of the stern where the sediment on the seabed is particularly soft. It seems that it was bombed a few years ago, so the stern has completely disappeared.

Fortunately, they encountered good hydrology.

Now the water temperature in this sea area is around 28c, the flow velocity is around 30cm/s, and the visibility is between one and two meters.

This kind of visibility is already a very good situation. After all, the water is not too deep and the water pressure is not strong. This kind of visibility can make it easier for them to find treasures.
