My system is not decent

After a diver enters the water, the first thing he does is to detect the water depth.

The water depth here is only 14 meters, and the waves cannot reach the sunken ship, while the seabed is hard and the current is slow.

Such an ideal underwater environment has even made people who have excavated other sunken ships in harsh environments feel intoxicated.

It's just that they can only find porcelain buried in sand, so the excavation speed is not fast.

During the day, they are busy looking for and digging porcelain.

At night, they used the ferry to monitor the shipwreck area.

On some nights, fishing boats loaded with diving equipment broke down nearby.

There is even a ship that has touched the alarm bells they have set up on the surrounding sea.

The pirates on the fishing boat confronted the team members, stopping and leaving from time to time. They dared not go into the water, but retaliated by preventing the team members from getting a good night's sleep.

The calm lasted only 10 days, because the typhoon came, and Chen Wenzhe and the others got a chance.

It's one of the worst things that can happen, but in danger lies opportunity.

The golden season for underwater salvage is from March to June. One of the reasons is that there are no meteorological disasters such as typhoons.

It will delay the time of excavation, stir up the sea water, and greatly reduce the visibility of the seabed.

However, for this excavation, the harm it brings is far more than that.

When the typhoon passes through, they must not go into the water, and when the typhoon subsides, the team members who have been trapped on the island for shelter from the wind for several days will go into the water again.

At this time, all the fishing boats peeping around had disappeared.

Those small fishing boats couldn't resist the typhoon at all, so they should have all evacuated from this sea area.

However, things are often not satisfactory, because after they go into the water, they find that the porcelain has been lost and damaged again.

The bulkheads of the wreck were ripped off, the baseline was torn up and the bottom was torn, and there were still stones used to tie buoys and fishermen's rakes.

And these newly-appeared buoys must be piracy.

Obviously, Chen Wenzhe's actions attracted the attention of the fishermen around them.

Therefore, when the typhoon passed through, someone went into the water.

In other words, these new pirates not only dare to steal under their noses, but they are not even afraid of typhoons.

In the midst of a typhoon, and dared to go into the water, those people really dared to go all out.

For the sake of money, some people dare to do anything.

Fortunately, the sunken ship had been stolen long ago, and there was nothing on board.

And what those people salvaged were only the fake salvaged porcelain that was newly put in above.

Think about it, is it worth it for them to go into the water under the situation of a typhoon for some counterfeit products?

Maybe it's worth it, because what they fear most is that they don't even have the chance to fight hard, right?

Chen Wenzhe and the others have already landed now, and they are all wearing shoes, so naturally they can't just work hard.

Therefore, it took more than a month to salvage the sunken ship this time.

During the more than 50-day excavation process, this water area encountered three typhoons.

On average, it happens once every ten days, and I can't work for two to three days each time.

Therefore, the excavation work of the sunken ship is intermittent, but the piracy occurs from time to time.

It's a pity that the things found on the sunken ship were all modern porcelain, and Chen Wenzhe was not a rarity at all.

It is because of the existence of this batch of counterfeit salvaged porcelain that they actually coexist peacefully in this sea area.

Of course, compared to Chen Wenzhe's salvage boat, those fishermen must have suffered losses.

During the typhoon, there was an adventurous fishing boat, which sank in the nearby waters.

Therefore, Gao Qijing and the others had to speed up the progress, and the exploration work that should have been carried out more fully had to be ended early.

More and more fishing boats gathered, complicating the situation.

What makes them feel the most urgent is to salvage the porcelain out of the water as soon as possible, so as to cut off the coveting hearts of other thieves.

However, after the typhoon, the visibility in the shipwreck waters dropped sharply.

According to Gao Qijing, the visibility in this sea area has been maintained at about 10 to 20 centimeters for several months, and has never improved significantly. At the lowest point, it was almost zero.

For the "treasure hunting" type of salvager, cloudy vision isn't an issue.

They can touch the cultural relics and bring them out of the water, but for the underwater treasure hunters, it is almost a disaster.

If you just salvage a deep-sea sunken ship, you only need to put down the steam claws at the sunken site, clamp the wreckage and pull it up to the surface, and you're done.

Chen Wenzhe's underwater treasure hunting work is by no means so simple and crude.

Because they want more, they need to search for more useful information.

Of course, they are also looking for clues within the scope of science, including various archaeological fields such as ancient porcelain research, navigation history research, shipbuilding history research, and maritime trade history.

Therefore, collecting all kinds of information on the sunken ship rather than fishing out the porcelain is the essence of the excavation work.

Only if you understand this, you may be able to find a series of treasure ships around.

Therefore, when the visibility is too low, the effectiveness of information collection will naturally be greatly reduced.

Fortunately, before the typhoon came, they had been able to lay special sulfuric acid paper under the water calmly, and draw a "detection map" with a pencil at a ratio of 1:20.

After the typhoon, they had no choice but to touch in the chaos, judge the position, shape, and proportion by touch, and draw the drawings by memory after returning to the ship.

After the drawings were completed, Chen Wenzhe figured out how the sunken ship sank to the bottom of the sea, and how the porcelain in the cabin was scattered on the bottom of the sea afterwards.

Of course, the most important thing here is the route, monsoon, typhoon and other issues.

Knowing this information, it is possible for them to find out all the sunken ancient transport ships around here.

With the desired information in hand, the next step was to fully excavate the porcelain surrounding this first shipwreck.

In order to excavate the shipwreck, Gao Qijing and the others carried out 6 experimental excavations, and even surrounded the whole shipwreck site within the mosaic frame.

Compared with other sunken ships, the contents of this ship have been emptied, but the porcelain buried in the nearby mud and sand is particularly well preserved.

"Wuhua is the best porcelain in the world; Kangyong is the best porcelain in China."

For the porcelain unearthed this time, Chen Wenzhe feels that it is the best among the proven underwater sites.

Under the influence of the weather, tides and currents in the southern summer, the underwater team members have very little time for launching operations.

Each time they go into the water, they can stay for up to 40 minutes, and each person goes into the water an average of 3 times a day.

In the deep sea, the consciousness of the team members is very blurred and it is difficult to concentrate.

Therefore, it is necessary to make all the plans accurately before diving, and hope to complete them as soon as possible after entering the water.

The hull and remaining cultural relics are buried under the silt.

The distribution of cultural relics under these silts has also been marked.

Afterwards, compare the blueprints, search for clues according to the drawings, and dig one by one.
