The Jiuma team stopped on the poplar tree by the river.

Sensing the southwest direction upstream, there were no large ships parked on the riverside along the way, and there were no large-scale shipyards in sight. There are only a few small villages by the river with a few small sampans on the tidal flats.

So, induct downstream. There are more shipyards downstream!

Pieces of logs are floating in the water, shipyards are appearing on the riverside, boats are being laid, wooden boats are being brushed with tung oil, but there is no Zheng He's treasure ship as big as the memory of the Bright Brothers!

"Why not?

"Lenovo, are we looking for the wrong era?"

Ma Lian: "We seem to have missed something! Hey, brothers, did we just look at other people's shipyards?"

"yes! What do you look at the shipyard?" the group asked.

Ma Lenovo: "Let's go back this time, and specifically investigate the place where no one is around!"

Sparrow Gold: "What's the reason for that?"

Ma Lian: "I can't think about it either! I have a hunch, if I still don't find it, count me as a blind guess." If there is a discovery, it should be in the uninhabited grass near the river!

The Jiuma team returned to the west. This time, all nine of them focused on uninhabited open space according to the suggestion put forward by Ma Lenovo.

"Huh, you sense the depression at 11 o'clock. I seem to have found something!" was flying by the river, and the sparrow rain reminded me.

"Huh, it looks like it's the bottom of a boat! Let's take a look!" Sparrow Ray sensed it.

Nine sparrows were parked on a half-built ship.

Ma Yinguo: "This boat is so big! It is estimated to be 100 meters long!"

Ma association: "It is likely to be Zheng He's treasure ship!"

Sparrow Gold: "You say, where is this hereafter?"

Ma association: "According to the memory of the boss of the deity, the later generation is a suspected Zheng He treasure ship excavated near the Xiaguan of Nanjing. If it is this boat, then this should be the next pass of the future generations! Unfortunately, the boss is not a geography student, so in our memory, there is no map of Nanjing. Otherwise, we won't have to fly around!"

Ma Karma: "Look, there are five masts! The six-meter big coffin is also soaking!"

Sure enough, to the southwest of the half-cut ship, five masts and a large door panel were thrown under an upside-down shed. No wonder I didn't notice it at first, and I was crushed under the rubble.

"These five masts, the longest is almost eighteen meters! This fan is really six meters long!"

Sparrow Gold: "How tall is this eighteen-meter mast? At least twenty-five meters! The thousand-year-old tree on our Hanchen Island is not that tall!"

Ma Cause: "No! That's not made of the whole tree, it looks like it's spliced!"

As soon as Ma Cause and Effect said this, the others sensed into the inside of the mast.

"Huh, really! How can the mast be spliced together? Isn't the spliced mast easy to bend? What kind of structure is this? Hmm? I can't understand it!"

When a group of papermakers studied ancient shipbuilding technology, they basically couldn't understand it! If they could understand it, they would basically be demons!

Ma association: "Well, cause and effect, this one is the longest, and it should be the main mast." You don't find it, except for this mast that is spliced, the other short points are all single wood. The strangest thing is that the mainmast has been preserved better than the other short masts over the years! And the mainmast is much better!"

Ma Cause: "When you say that, I also notice the difference! What do you think is the reason for this?"

Ma Lian: "I can't say it either! Let's go to the hull of the ship and take a look! I have a suspicion that the keel of the big ship is probably connected by a similar method!"

A flock of small sparrows flew towards the hull again.

"It's a pity that such a good ship was thrown away halfway through. By the way, Lenovo, how do you think you can find clues in a place where no one has a boat?"

Ma Lian: "I was thinking at the time, according to historical records, the last time Zheng He went to the West, the emperor of the Ming Dynasty was no longer the Yongle Emperor! Zheng He was no longer Zheng Da's companion! and he was not treated by the new emperor. Therefore, half of the new ships were also stopped.

However, Zheng He was, after all, a confidant of the former emperor! No one knew whether he would regain power? Therefore, I am afraid that no one would dare to move this half-pulled boat.

After more than ten years, Zheng He died. But this ship, exposed to the sun and rain, also decayed. That's even more of a nobody's idea!

If the treasure ship is thrown in the open air, no one will be responsible! But if someone moves, if the emperor wants to go to sea on a whim one day, he will think of the treasure ship! The guy with itchy hands will definitely be unlucky!

You say, will anyone move a rotten bottom that can only be used as firewood?"

"Well, no one is going to look for a stall! Makes sense!" Everyone agrees with the reason for Ma Lenovo's speculation.

Of course, no one else should not approve of it! Because, I really found a big ship.

"Hey, Lenovo, the keel structure of the big ship is really very similar to the main mast! It is also more corrosion-resistant than other parts!What kind of technology is this?" Ma Causal with the guess of Ma Association, discovered the strangeness of the keel of the big ship earlier than others.

The reason why Zheng He's treasure ship was able to build a length of nearly 100 meters at 33 zhang was a breakthrough in keel technology! And the keel splicing technology, in the final analysis, is glue and mortise and tenon technology.

Mortise and tenon technology, as long as you are a top carpenter, you can basically master it. The problem is glue!

The glue used to make keels and masts should not only be convenient for construction, but also resistant to seawater erosion, and more importantly, have sufficient bonding strength! It's a pity! It's lost! Otherwise, we can also imitate a Zheng He treasure ship!"

Sparrow Lei: "Why is there such a powerful glue? The Ming Dynasty is not a later generation, there is wood glue, there is epoxy resin." ”

Ma Cause and Effect: "Don't underestimate the wisdom of the ancients. During World War II, the British used a kind of shellac to build an all-wood Mosquito airplane. It's an airplane that can be used in real combat!"

"Wow! That's amazing! I'll have to take a look!" Sparrow Ray heard for the first time that airplanes could be made of shellac and wood.

After noting down the mast and keel structure and bottom structure of Zheng He's treasure ship, the Jiuma team flew east along the river. It's hard to get out of it, and I haven't had enough of it!

After flying for three days, I arrived at the mouth of the sea. At this time, the estuary of the Yangtze River was not like that of later generations. The magic capital is still just a tidal flat! Only Songjiang County.

The Jiuma team didn't dare to have too much contact with humans, for fear of alarming the Heavenly Dao Mark!

When you get to the East China Sea, you can't pretend to be sparrows! Nine Haiou flew south along the coastline.

"Huh, cause and effect, isn't it the Diaoyu Islands at ten o'clock ahead?"
