After the meal, there was enough rest, and a group of divers prepared in advance, and some of them had already entered the water first. Zhang Nan put on a three-millimeter-thick wetsuit, and then prepared to dive.

The maximum water depth is 18 meters, and there is a diving rope with a lead sinker hanging from the sun deck of the yacht to the bottom of the sea, and there is an eye-catching mark every five meters, but even so, Zhang Nan still has to wear a diving watch and be fully prepared.

I am not a professional engineering diver, I honestly dived for a while, waited stupidly for three minutes at the depth of 5 meters at the diving mark, and then dived to a depth of 10 meters: I omitted the step of "waiting for five meters" when diving ** meters before, but this will not work, you have to take your time.

Wait another two minutes at a depth of 10 meters, then another two minutes at 15 meters, and then descend to the seabed in front of you.

The eardrum was a little painful at first, but fortunately it was within the tolerable range, and it didn't hurt anymore when it came to a depth of seventeen or eighteen meters under pressure: the pressure inside and outside the human body had been balanced.

Even if there is an important situation, Zhang Nan had better not rise quickly, otherwise he will get a portable decompression chamber to stay for half a day before he can come out of 18 meters, don't look at it is not particularly deep, in fact, any depth is dangerous for diving.

Once you reach the bottom of the sea, you will find coral reefs and beautiful fish around you, which is a fun dive.

But it soon turned out that this dive was interesting, but the wreck was not very interesting!

The ship was small and almost surrounded by coral, and when the rotten planks were chiseled open in the areas where the coral was weak, it was found that the ship probably sank more than 100 years ago.

Because the divers found an air dead wind lamp, covered in glass, combined with some rusted iron utensils found, it was judged that this was a fishing boat.

Leaving a few divers to see if there was anything missing, Zhang Nan spent seven or eight minutes ascending in sections, and as soon as he got out of the water, he said to Philip who was waiting: "There is a fishing boat below, let the 'Big Shark' change anchorage in an hour to go to the last point." ”

The tone is not disappointed, normal.

This has been salvaged underwater by many boats, this is the first time that it has really run away, and it has been taken care of by God, and there is nothing to be dissatisfied with.

Philip noticed that the boss only said that the cargo ship should be replaced, and that the yacht was obviously not among them, and he didn't ask much, maybe the boss didn't want to follow him again.

Ten minutes later, the diver came up and saw that the boss was actually sorting out a few fishing rods, and it was clear that the coral reef and sand bottom below were full of all kinds of fish, which was definitely a good place for sea fishing.

After a while, before the "big shark" sailed away, Zhang Nan began to catch fish: sea bream, grouper, needlefish with a length of nearly one meter... Moray eels with thin wrists are all on them.

The water below is shallow, and the bottom is not much sandy, otherwise this moray eel will catch more.

The American guy doesn't seem to have the habit of eating moray eels, but Zhang Nan and Boss Guan like it very much!

Like in the place where Guan Boss grew up, the fishermen's rules: there are guests who can't serve the fish if the grade is not enough, but the moray eel is a good thing, marinate it with salt first, and steam it to be properly delicious!

Since Zhang Nan was too lazy to move here, Guan Xingquan and a few guys simply drove the traffic boat out to troll in a deeper sea area, and it was not necessary that there would be big fish.

But I didn't expect to come back in less than an hour, there was an extra 3-meter-long sailfish on the boat, it is said that if it wasn't for the fast flash, it would almost make the big Mark feel cold when he caught it!

Sailfish, that also has a pointed jaw!

The fish resources in the South China Sea are so abundant that it only took three hours to catch a super bumper harvest, and the two guys who helped with the fishing have hardly stopped.

Originally, I was thinking of fishing again, but the first time the "big shark" went into the water to clean up tentatively, there was news that many broken clay pots were found on the bottom of the sea, and a diver also found dozens of rusty, all cemented copper coins in a broken clay pot.

"Copper coins?"

Zhang Nan had just caught a two-pound sea bream, and after hearing Guan Xingquan's words, he hurriedly asked.

"Round square holes, what do you say?"

For the Chinese people, the name of this copper coin is only limited to the ancient round square hole money of China and neighboring countries; as for the copper currency in the world that has no hole in the middle, the ancient goods will be called copper coins, and the modern ones are called copper plates.

Boss Guan asked rhetorically, which made Zhang Nan understand the situation and have to go over and take a look.

5 nautical miles away, there was no need for Zhang Nan to rush to hurry, a high-speed traffic boat on the side of the "Big Shark" had already set off to send the samples over.

After a while, the things were in Zhang Nan's hands.

Most of the copper coins have been cemented together, and the handwriting is blurred, but this is not difficult for Zhang Nan.

Distinguish carefully, "Five baht." ”

You can't be mistaken, it's five baht.

With that, he looked up at the group of "curious babies" following on the side, and added: "Don't ask me when this is this, this thing Emperor Wu of the Han Dynasty will start to make, and it will stop casting in the fourth year of Li Yuanwude in the Tang Dynasty, and the casting time is more than 700 years, and the folk circulation time is at least more than 1500 years. ”

This is the truth, Zhang Nan understands ancient Chinese coins, even if he is not at the expert level, he can be regarded as a knowledgeable person.

There is a saying in the circle that "play with money does not play with five baht", because there are no friends who play this thing, even if you really have a rare variety of rare five baht coins at hand, then no one will play with you!

Everyone doesn't play, what else do you play?

Why not play?

The five-baht coin variety is as vast as the stars, looking at half a catty to eight taels, except for a very few versions of the characteristics are obvious, the vast majority of them look the same, "good and bad, rare and difficult to distinguish", it can be said that since ancient times the collection does not charge five baht!

What is the Western Han Dynasty five baht, the Eastern Han Dynasty five baht, the two Jin and Northern Dynasties five baht, the Sui five baht, the cut edge five baht, Dong Zhuo five baht, Shu five baht... This is the most brutal distinction, and there are too many five-baht varieties that have been minted for more than 700 years!

If someone says they can recognize all the five baht dollars, then he's 100%!

The five-baht coin was still used in the Ming Dynasty, at least there were five baht in the batch of Hongwu cellars that Zhang Nan dug up from the cellar of Xixi Wetland in Hangzhou. As for later......

When Zhang Nan was a child, he found five baht coins in the corner of his grandmother's old drawer, which means that at least until the Qing Dynasty, the common people still recognized these five baht coins.

The Braided Dynasty may prohibit the circulation of Ming Dynasty currency, but it will not care whether the common people occasionally mix the currency of the previous dynasty, just like the Qing Dynasty, there will never be an official government to check whether the people have a "Kaiyuan Tongbao" in their hands.

As for the origin of the five-baht coin in the Ming and Qing dynasties, there may not be many that have been handed down to the world, but imagine the terrifying amount of the five-baht coin...

There are dozens of tons dug up at a time, which was all money in ancient times! When the amount is large, it may be that when the copper is sold for the time before, what tens of hundreds of catties will be spent.

There were only a few dozen five-baht coins in this broken jar, Zhang Nan broke them open and looked at them, they were all corroded by the seawater like rotten iron, and there were no other coins mixed with it.

These five-baht coins alone cannot judge the age of the shipwreck, and it is not easy to judge: it is possible from the Western Han Dynasty to the Tang Dynasty, which is longer than the combined time of the Yuan, Ming and Qing dynasties.

"Where's the clay pot?"

asked the guy who drove the boat, and this said: "It's still in the sea, it's basically broken, and it won't be salvaged until the photos are taken." ”

Zhang Nan said "um" and said to the crew on the side: "Anchor, let's go over and have a look." ”

Take pictures and videos, there are a lot of these procedures, as for what to do first, just do it and then salvage.

We are fishing for treasure, not archaeology.

……

When the yacht docked on the cargo ship, Zhang Nan climbed onto the cargo ship again, and it didn't take long for the first basket of pottery to be sent to the deck.

The wreck below was basically completely buried by sea sand and silt, and the wooden components were almost completely decayed, leaving some broken pottery shards on the seabed.

After the divers took another photo, they finally dug up a good potbelly jar, and sent it first.

As soon as the net basket with steel bars and plastic ropes was opened and the contents were clearly seen, Zhang Nan said, "Double cans." ”

It is a straight-mouthed jar, with a short neck, a bulbous belly, a concave outsole, a height and a diameter of 234 centimeters, and some fragments of other jars on the side.

Take the jar out of the basket and put it on the deck to take a closer look: the shoulder and abdomen of the jar are decorated with string patterns and water ripples, and the leaf veins are double-systematic, and the surface of the jar is not all rough pottery like the Han jar, and there are some cyan substance remains.

Guan Xingquan on the side also had a good look in his eyes and said, "There is glazed water." ”

"Hmm. ”

Zhang Nan finished this "um",

A large fragment was taken from the basket and looked closely: it was part of the neck of the jar.

It's very barbaric, knocking directly on the deck, and it doesn't break with a "bang".

He has seen a lot of broken things, he is not playing archaeology, he forgot the fragments on the deck, and then stomped on his feet!

Divided, satisfied.

Zhang Nan wants to see the fragment section, and the fragment has been soaked in the sea water for too long, and the original section can't see the reason at all.

Now it was clear, I looked at it a few times, and then looked at it carefully with a magnifying glass.

"The things of the early Three Kingdoms period of the Yue kiln, this glaze water is about to corrode away. ”

No wonder it is regarded by divers as a clay pot, the glaze layer on the surface of the jar is very badly peeled off, and it is difficult to judge under the water.

Yue kiln, Zhang Nan has handled the number of Yue kiln celadon will make those experts embarrassed, and he is not only a "practical school", for Yue kiln, but also learned the essence of the "theoretical school" from Nong Bosheng, to be a Yue kiln celadon researcher is estimated to be qualified.

Guan Xingquan didn't know until Zhang Nan saw the ability of Yue Yao and knew that he was unlikely to lose his eyes, but he still had a question: "How did you break the dynasty?"

Recognize the kiln, Guan Boss does not have Zhang Nan's ability: more than 20 years of front-line experience is not something that can be learned by listening to it and looking at it.

"This jar is a common style and ornament in the Three Kingdoms and the Western Jin Dynasty, and it still belongs to the early type, and the two series of jars that came out of some tombs in the Western Jin Dynasty began to rise, and the ornaments were also a little different. ”

As he spoke, he handed a piece of fragment that he stepped on his hand to Guan Xingquan, "Look at it, the tire quality of the Yue kiln products in the Three Kingdoms period is firm and fine, the fetal bones are mostly light gray, and the residual glaze is also clean."

Moreover, from the experience I got from the agricultural curator, the decoration of the early Yue kiln in the early Three Kingdoms was simple, and the typical patterns were water ripples, string patterns and leaf vein patterns.

In the late Wu period, the decoration of Yue kiln porcelain became more and more complicated, and oblique checkered patterns began to appear.

As for the Western Jin Dynasty, there will be such a porcelain jar, but the carcass is generally thicker and heavier than this, and the tire color is darker than this, at least gray, or even dark gray, and the glaze layer is thicker than this, and the glaze is also darker. ”

What is an expert?

There are not only real museum experts to guide you, but also a large amount of front-line construction site Taobao experience, this is the expert!

How many times a year can your archaeological team dig a kiln?

Three or five times is too much, right?

Zhang Nan was able to dig hundreds of times a year!

Experts, that's not blown out, it's actually done!

Previous reports had stated that such broken jars were everywhere on the seabed below, and that the edible item was apparently cargo, not a daily item for the crew. Besides, unless it is the boss of the ship, otherwise a crew member will use a Yue kiln celadon double-series jar during the Three Kingdoms?

It also seems a little too extravagant.

At this point, Zhang Nan didn't look at the jars and broken porcelain pieces on the deck, but looked at the scorching sun in the west, and almost shed tears.

It was an amazing feeling, it was amazing!

1,700 years ago, a long-distance wooden ship was shipwrecked here, where did it go?

17 centuries, when the Roman Empire was still there, where was it going?

There will already be people on many of the islands around here, but basically they are helping the savages, and the Chinese ancestors should have arrived here, but it was too early to change this damn wild land near the equator.

The voyages 700 years ago were full of dangers, not to mention the 1700 years ago, there was a sea trade at that time, and this time I was really touched by myself, which was a magical feeling.

Its final destination will definitely not be a nearby island, and the only option is to cross the Strait of Malacca, which is not far away!

Guan Xingquan also thought of this and said: "I didn't think that the Maritime Silk Road would exist at that time, it's amazing!"

When Zhang Nan heard this, he laughed, "It has been there for a long time, and there are maritime communication routes recorded in the "Hanshu - Geographical Chronicles", which is the early maritime Silk Road.

At that time, seagoing ships carrying all kinds of silk went out of the East China Sea and the South China Sea, and it is said that there were long-distance seagoing ships in the pre-Qin Dynasty.

After Qin Shi Huang unified Lingnan, the Panyu area now has a considerable scale and a very high level of shipbuilding industry in the Yangcheng area.

After Emperor Wu of the Han Dynasty, merchants of the Western Han Dynasty went to sea to officially open up this maritime Silk Road.

According to the records in the "Hanshu Geographical Chronicle", the route started from the territory of Xuwen-County, the southernmost part of Nanyue Province, and the territory of Hepu-County of present-day Gui Province, and entered the Malay Peninsula, the Gulf of Siam, and the Bay of Bengal through the South China Sea, and arrived at a Huangzhi country and Chengbu country in the south of the Indian Peninsula, which is today's Sri Lanka, which is also the earliest written record of the Maritime Silk Road that can be found now.

During the Eastern Han Dynasty, there are also records of how the Han Dynasty and the Roman Empire interacted with each other, and the silk that drove the Roman aristocracy crazy was not only transported by camels: Chinese merchants took the sail ships built by the Han Dynasty themselves, first from the north to Yangcheng by sea to trade, and then transported silk and porcelain by sea to Malacca through Sumatra to ancient India, and then purchased spices and dyes to be shipped back to China.

Later, those ancient Indian merchants sent silk and porcelain to the port of Cairo in Egypt through the Red Sea, or through the Persian Gulf into the two river basins to Antioch, and then Greek and Roman merchants transported them from Alexandria, Gaza and other ports in Egypt to Greece and Rome by sea in the Mediterranean.

During the Three Kingdoms period, the state of Wu dominated Jiangdong, and at the end of the Han Dynasty, the Three Kingdoms were still in the critical period when the Maritime Silk Road shifted from land to sea.

It is said that Sun Wu's shipbuilding industry has reached the international leading level, and Sun Wu's silk weaving industry has far exceeded the level and scale of the two Han Dynasty, and for the first time, the official silk weaving was founded, and the celadon and silk were sold to ancient India, and the absolute profiteering in the profiteering. ”
