"The best wood for shipbuilding is teak. However, teak is scarce and precious, and is generally only used for ship decks and keels, and the most common woods used in shipbuilding are pine and fir. The so-called pine soaked for a thousand years, and fir blowing for 10,000 years is what it means.

The keel of this wreck is made of teak, and the bottom part of the ship is made of pine, which has been soaked in seawater for hundreds of years without decaying, and if my guess is correct, the wood is also soaked in water for three years, then exposed to the sun for three years, and then soaked in tung oil for three years......"

When it comes to shipbuilding technology, Long Zhi is endless, you must know that as a captain, his understanding of ancient sailing ships is no less than that of Professor Fang's academic school.

Chen Xiu listened to his explanation and looked at the half of the shipwreck in front of him, and suddenly he had a great understanding of the ancient shipbuilding technology and benefited a lot.

"Shizhou, enter the shipwreck. Professor Fang saw that Long Zhi was so happy that he almost forgot the purpose of this sneak, which was to directly grab the microphone and give an order to Shi Zhou, the pilot of the submersible.

"Yes!"

Shizhou first floated the submersible to the part of the wreck that leaked out of the seabed silt, only to see that there was an irregular crack hole three or four meters large at the bottom of the ship.

"The shipwreck must have hit the reef at the time, causing the cabin to flood, and finally sank!"

The submersible kept detouring the port side of the hull, and Professor Fang's hurried voice suddenly came from the earphones, "Stop, this is it!"

Shizhou fixed the submersible in this position, and all the spotlights were aimed at the port deck, and I saw that hundreds of square words were densely engraved on it.

"Pull in a little more!" Chen Xiu shouted.

Shizhou was closing the distance of the submersible, and finally saw the words on it clearly, each word was obviously carved with a sharp weapon, which can be described as a real three-point into the wood.

But what shocked Chen Xiu the most was not the carving method of those words, but that he didn't know any of those words!

These characters are not oracle bone inscriptions, nor are they gold inscriptions, but they are more cumbersome than ancient scripts in terms of structural strokes.

At first glance, it looks like the writing of various countries in the Spring and Autumn Period and the Warring States Period, but Chen Xiu also understands the writing before Qin, and it is already close to the official script written in the later affairs, and it is not like the words on the deck.

On closer inspection, it feels a bit like Tangut script, but it is plausible. If you split the radicals, it looks like the "harmony of Chinese characters" in the text. But when I look at the strokes, the writing method is different.

"Professor Fang, which country's text are these, how do I feel that my books have been read in vain, and I don't know any of them!"

Professor Fang in the control room smiled bitterly and said, "I don't know either, your mission this time is to decipher these words!"

"I'll decipher!?"

Chen Xiu finally understood why Huang Nanguo's three problems in the assessment of so many experts were all related to words.

It turned out that he was going to pick out someone with special skills in archaeological writing to decipher the text on the shipwreck.

But the problem is that although I have to read the oracle bone inscription during the assessment, it is all about cheating!

In terms of true talent and practical learning, it is that the 800 commonly used Chinese characters may not be able to be written correctly by hand. After all, this is a computer age, and it is most normal to forget to write a pen.

"We initially suspect that these words were engraved on the death of the people on board when the ship was about to sink. It was engraved with three hundred and fifty-six words, but it was incoherent, and some of them disappeared with the disintegration of the other half of the ship's hull.

We have already taken pictures of these words before, but in order to give you a direct impression, this dive has been specially arranged for you to observe up close. ”

Chen Xiu was crying out for a while in his heart, not to mention observing it up close, even if he let himself engrave it on his chest one by one, he was afraid that he would not be able to recognize it.

At the moment, his eyes were staring at every word engraved on the deck, although he didn't understand the literal meaning, but looking at the handwriting on it, he suddenly exclaimed "Huh!".

"Expert Chen, did you find anything?"

Professor Fang on the other side of the console heard Chen Xiu's exclamation and asked anxiously.

"The person who left the inscription should be a martial artist, either a master of swordsmanship or a good hand with a knife!"

When Professor Fang heard him say this, he was stunned for a moment, and then asked, "How are you so sure?"

"These words were obviously carved with sharp weapons, but these words are extremely smooth, and there is no trace of repetition, and it is impossible for someone with strong wrist strength to carve such words!"

Listening to Chen Xiu's analysis, Professor Fang asked Shizhou to push the live broadcast camera inside the submersible, and looked at the words on the upper deck that were indeed the same as what Chen Xiu said, and couldn't help but think in his heart: "Mr. Huang told me at the beginning that he had found an expert who was very knowledgeable and talented in the study of words, and I didn't believe it when he first got on the ship, and I have been studying these words for a long time and have never had a direction! Is it really related to that knife?"

Chen Xiu watched inside the submersible for a long time, but he still had no clue, and finally the oxygen in the submersible was about to run out, so he had to float back to the ship.

......

"Chen Xiu, I'll take you to see something!"

As soon as he returned to the ship, Professor Fang couldn't wait to take Chen Xiu to an independent secret room on the ship, and carefully took out a box from a safe.

Before the box was opened, Chen Xiu's palms first warmed up, this feeling Chen Xiu was very familiar, and he couldn't help but think expectantly: "What is in here?"

Professor Fang opened the box and took out a long knife similar to an Oriental knife, with a slightly different shape, slightly shorter than the general long sword, with a thick back and a thin blade, like a razor, but the whole blade has a curve, and the handle is quite long, but the blade is simple, dull and unpretentious, and it looks like it has been some years, but looking at the blade still makes people shudder.

"Embroidered Spring Knife!"

Chen Xiu handed over the name of this knife at once, and Professor Fang nodded and said: "Your vision is very accurate, many people can't tell the difference between embroidered spring knives and Miao knives! This embroidered spring knife was salvaged from the wreck not long ago!"

"What!"

Chen Xiu was very surprised, if those ceramic products could be soaked in seawater for hundreds of years without rotting, he didn't think it was strange, after all, those ceramics were not afraid of the corrosion of seawater. But it was really shocking to him that such a steel knife could be soaked in seawater for hundreds of years and still be in such good condition.

Although there have been unearthed in the Spring and Autumn Yue King Goujian sword before, it is claimed that it can cut the kraft paper when it is unearthed, but the bronze sword when the Spring and Autumn Yue King Goujian sword is inherently better than steel, and the more important thing is that the unearthed Spring and Autumn Yue King Goujian sword is not soaked in seawater.
