At this time, how did the six space-time smugglers know that thousands of miles away, there would be a pair of sinister blue eyes staring at them, and they also had a bad idea against them!

They also did not think that the Tatars were good at using spies. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Of course, since the two sides have never cut off commercial and trade activities, it is not a big deal for such a thing to occur, and it is not yet time for the north and the south to tear their skins.

In real history, they will need another two full years!

Wanshida also specially inspected the sea vessels prepared for them by the city's shipping department, which is the top priority.

He was happy to see that the dozen or so were all old sea boats!

This is good, the shipbuilders of the Great Song Dynasty are good at using nailing, tenon and riveting structural processes to build ships, for the sea ships built in this way, the old sea ships are more durable than the new sea ships.

At this time, the three major inventions of ancient shipbuilding technology: stern rudder, watertight cabin, pointed bottom shape and keel structure, have been widely used in ocean-going ships.

However, for those extraordinarily large sea ships with a load of tens of thousands of hu, only the bauhinia wood and ebony wood in the Qinzhou area of Guangxi are the most suitable, because the wood is several zhang long and well-organized, and it will not be damaged even if it encounters vicious winds and waves.

For the pointed keel structure, although the Great Song Sea Boat was applied early to break the waves, but because the draft is not conducive to shallow water navigation, at this time, the Great Song Dynasty began to like to build flat-bottomed squid boats, such as the combination of the seventh and eighth plates on the left and right sides, each with a long log with a semicircular cross-section, longitudinally installed on the outboard, its role is to enhance the concealment of the ship, called the anti-shake keel.

Later, Western wooden boats also had such a structure, but it was hundreds of years later than in China.

These dozen or so sea vessels are of this type.

Wanshida burrowed into the cabin and examined it carefully, especially for the largest of them, which they were going to sit on.

He saw that the sea vessel used the triple plate process, and found that the connection tightness of these multi-plate structures was okay, and it could fully withstand the invasion of wind and waves for a long time.

It was then examined whether the joints between the decks were mixed flat or lap joints.

Due to the multiple plates of the hull, if there are gaps between the planks, the hull is very easy to corrode quickly, which requires his inspection work to be meticulous.

The stress conditions of the hull parts of the sea vessels are different, so it is necessary to carefully check the quality of the wood in different parts.

Generally, the material of the side panels, the bottom plate and the bulkhead panel is of the highest quality.

Wan Shida saw that the side panels, the bottom panels and bulkhead panels were mostly made of whole timber, and he carefully measured the thickness of the planks.

Generally, the thickness of the inner layer is more than 80 mm, the middle layer is about 50 mm, and the outer layer is 45 to 50 mm.

He focused on checking whether the keel of the hull was made of masson pine, because the horsetail pine was thick and corrosion-resistant, but fortunately, it was indeed a masson pine material.

He also looked at the ribs, the head column, the rudder bearing, the mast and the winch axle of the ship, which should generally be made of camphor wood, fortunately, there is basically no need to make major repairs, only need to replace some small pieces.

He finally looked at the quality of the rib installation at the junction of the bulkhead and the hull board, which could also be made of camphor wood.

Generally, the ribs in the front half of the hull are installed behind the siding, and the ribs in the second half of the hull are installed in front of the siding, which can strengthen the bulkhead and improve the overall solidity of the whole ship.

Wanshida's inspection made Fa Keti who accompanied him embarrassed, he really didn't trust the shipbuilding technology of the Great Song Dynasty, and he was professional enough.

Wanshida walked up and down, inside and out.

The quality is okay, it can sail safely, but it is a pity that this is not the largest sea ship, and it is an official ship.

During this period, the largest sea ship in the Great Song Dynasty could carry 1,000 people, with a maximum of 12 sails, hundreds of tons of cargo, and a rudder length of several zhang.

This kind of giant sea ship was far ahead in the world at that time, and the "Zheng He Treasure Ship" of later generations also inherited and carried forward the advantages of shipbuilding in this period.

If it is an official ship, it means that they usually do not pay much attention to maintenance, and the surface of many places is in tatters, and the worst thing is that some cabins are smelly and coaxing, and they have shipped a lot of dung!

Wanshida ordered the captain of each ship to take the sailors to start washing with clean water, and the unqualified report was that the boss changed people and changed ships!

I don't know if this is the official family of the Great Song Dynasty to listen to us?! Otherwise, we don't care about your national fortunes!!

This was a terrible remark, and the captains of the ships began to scour and clean with their sailors.

Wanshida is really wrong to blame the people of the city, this is still looking for a good quality sea boat.

Ordinary official ships, it's generally good to float.

Seeing that they were using flat trapezoidal skewers that could be adjusted by the direction and strength of the wind, Wanshida concluded that the sailors would probably use the zigzag method of sailing and could sail down to any wind.

I asked the sailors carefully, and sure enough.

But some of the sails are also tattered, so you can't change them right away!

The captains were pleased, for it was too much effort to find the repairs that were usually required to repair the ship, but this time it was good, and even the rigging could be replaced with a new one.

There was also a great improvement in this period when it came to nautical technology.

After Shen Kuo discovered the geomagnetic declination, the water floating magnetic needle was applied to ship navigation.

After entering the Southern Song Dynasty, the shipwrights combined the water floating magnetic needle with the parts with the orientation marker into a complete instrument, which was later called the "compass", which opened a new era of world navigation technology.

After that, the compass was introduced to the Arab region and European countries with the merchant fleet, and it strongly promoted Western navigation.

However, the comparison between their compass and the professional sailing compass carried by Wanshida is not to be mentioned.

In this time and space, he is the only one in the world who can use a sextant.

Therefore, there is basically no problem for everyone to go to sea together.

Song Ziqiang didn't care that everyone went to sea together.

He said lightly: "The sailboat, it won't be deducted all at once, if there is really any accident, as long as there is a few seconds of preparation time, everyone can cross back." ”

Of course, everyone will be in the same boat.

According to their request, the Great Song government also provided 3,000 soldiers.

They all meet their criteria: they are all people who can do farm work.

As for the other craftsmen they chose, they were all satisfied.

These people were all handed over to Wu Dapeng to integrate, this guy likes to manage people's work.

Later, Zhang Guoan also went to help.

Wan Shida, Song Ziqiang and Wang Defa began to refit the flagship they had already selected, which was the three-masted ship with a tonnage of 200.

They mounted four bed crossbows on the left and right sides of the ship. At this time, Faktihar, who had been accompanying them, finally understood the labor-saving effect of the so-called pulley group.

Two and a half sized boys can pull the cow tendon the thickness of the thumb into position!

This would have taken two prime years to do.

So why is this happening?

Watching people busy back and forth, he didn't have the embarrassment to ask, so he went back and tried to do it repeatedly, anyway, he could see it.

Then the Phaktihar understood the use of the iron pipes, and it turned out that they were making assault rifles...... But it's too fine, and it can only hold a little gunpowder, and I'm afraid it will only smoke.

Six space-time smugglers, commanding a group of half-sized men early, loaded their own things onto the largest ship.

They also had "001" painted on the sides of the bow, indicating that this was the flagship of the fleet, and of course, the 200-ton tonnage could still be called a ship in this time and space.

They began assembling the Rumi arquebus on the ship, while Faktisha observed.

Just to let out a puff of smoke, as for spending so much energy?

Wang Defa saw that the official uniform on his body was still the same as before, and knew that last time he hurriedly got the bogie of the four-wheeled/big carriage, it seemed that no one cared about it.

Wang Defa discussed with everyone and proposed to let this Fa Keti give Lumi arquebus again.

Everyone thought about it and agreed.

They originally wanted to wait for themselves to develop it and sell it to them, but they felt that the structure of this Lumi arquebus was too simple, and with the craftsmanship level of the Great Song Dynasty, they could completely imitate it.

There is a basis for this, when they asked those craftsmen to make it in the armory, they found that they made it without any difficulty, and the size was quite qualified in all aspects.

Besides, long carpenters, short blacksmiths, some parts are about the same, they have large, medium and small frustration knives.

Wang Defa took an assembled Lumi arquebus and said to the confused Fakhothi: "This thing is called an arquebus...... In Yindian, we are used for hunting...... When a friend comes, you have a good wine, and when a jackal comes, you have an arquebus, so it's okay to hit someone. ”

Fakotisha laughed silently, this man was really joking......

Hu Zhenbei, a blacksmith who had been eager to try beside him, said: "A certain is a talented blacksmith, why don't you let a certain teach him......"

Okay, this blacksmith from Hu Zhenbei is a good teacher, and he just saves his own things.

Wang Defa asked them to go ashore to find a remote test gun.

Hu Zhenbei blacksmith said: "Give a certain box of matches......"

"No, you have flint and velvet!"

Well, let's be stingy, Hu Zhenbei blacksmith took Fakti ashore to find a place.

They began to equip the bow with whaling cannons.

Just make the base of the bow thicker and rivet it stronger, and don't expect it to drag the whales, they will use ropes and wooden pontoons to deal with the whales.

The body of the whaling cannon is cast, and they have personally instructed this, so it is not too thick, and it can hit the whaling cannon shaft twenty or thirty meters.

As far as the eyesight of whales is concerned, the older ones, in general, they can't see their tails as far from the surface of the water.

After they finished setting up, Blacksmith Hu Zhenbei and Blacksmith Fake returned, and judging from the black ash on their faces, they both let go of their guns, and more than once.

Fakoti said, "I see, if you hide in a secret place, or if you are at the head of a city, when the enemy comes forward, you will shoot him, and the other party will surely die!"

Haha, I see! ”

, what do you understand?!

Wang Defa smiled and handed him a packet of gunpowder.

This is a granular type prepared by Zhang Guoan, not a dust-type black fire/medicine of the Great Song Dynasty.

Fakotihar smiled again, small, and his teeth were quite white.

"Give an arquebus......

"No, you go back and find a craftsman who has built it for us!"

Well, let's be stingy, Phakti turned around and was about to go to the armory.

Wang Defa thought for a while and said, "Do you know how to process lead bullets?" ”

"I know, Blacksmith Hu is really talented, he told a certain ......"

Wang Defa thought for a while and said, "Do you know how to process gunpowder?" ”

"I know, Blacksmith Hu is really talented, he told a certain ......"

"You control the temperature?"

“……”

"Forget it, Fa Keti Ha, you go and try it again......"

Industrial thermometers are consumable parts, but I can't give them to you, try them yourself, if you can think of artillery.

"Wait a minute, don't be in a hurry! Do you know how to make your superiors look at it? ”

“……”
