Numerous huge curtains enveloped the entire ship.

The boathouse in the deep-water port is a huge hull warehouse, and the length of the warehouse in the north-south direction is dozens of zhang away, and when you look at one end of the warehouse to the other, you will feel that the person on the other side is a small idea.

The longship mast is a standard large ship.

The three masts stand tall and upright, and they are painted to ensure that the hull is not eroded by water vapor. Unlike ordinary ships, this ship does not have high teeth and no floors, but only a high pavilion at the stern. However, at this moment, the whole ship was covered with a tarpaulin, and the face of the ship could not be seen. The captain of the trough beckoned the men to get on the boat and put away all the pieces of cloth covering it!

It was a huge project, and even if more than 30 people got on the ship to start work, it would take some time to remove all the curtains that covered it.

Taking advantage of this gap, the head of the trough asked Liu Tingyu to rest on the side, and took out some documents to ask him to look at.

"Set sail!"

The crowd got busy.

......

After a meal, the tarpaulin on the ship was gradually pulled away, and the behemoth gradually revealed its appearance.

The guards around Liu Tingyu stopped what they were doing, and all looked at this amazing huge ship intently! The tiled deck made the whole hull look like a spacious and bright square, and in it stood wooden planks as tall as a wall, which were also wrapped in iron sheets.

Remember the URL

The bow of the ship was still not visible, and the sailors were carefully removing all the tarps that covered the bow. But the towering shape is already imaginative!

The swordsmen on land have been fighting in the north for a long time, and they have not had much experience with boats, and they will only see some ordinary ships on the banks of the Yellow River! But if we compare this kind of boat with the ships seen on the side of the Yellow River, the boats on the side of the Yellow River can only be called small boats. Fishing boats!

More than I imagined, even when I came to Dongting Lake, I saw some big ships, but they could only be said to be big merchant ships at best!

And the ship in front of you is not called a merchant ship, but a warship in the real sense!

Heavy warships!

When the ship appeared in front of him, even Liu Tingyu glanced at it and never looked away.

The well-informed man in white has extremely rich experience and knowledge, although he is not impressed by the enormity of this ship, but being able to build such an armed heavy warship is still enough to make people sigh at the wisdom and creation ability of these craftsmen today!

Seeing that Liu Tingyu was interested in this, the trough chief followed him and followed him to the boat.

Since the beginning of China, there have been few water wars, and the water armies are almost all in vain. Warships are mostly used for coastal protection, but the Dahua Empire is strong, and the countries around the sea route are some small countries, weak countries, they don't even have time to take care of their own domestic affairs, how can they have the energy and strength to make powerful warships. Therefore, the Chinese navy has made some achievements on seagoing ships, but it is mainly used to fight pirates! It can almost be said that it is a knife used to kill chickens.

Sea ships are different from river boats, and the Dahua Empire has a unique kind of vehicles and ships in the navy, which greatly promotes the development of the navy and water warfare.

Like a giant combat vehicle, the ship can be between 20 and 30 zhang long, and has as many as 24 wheel pulps. It can be said that it has continued the glory of the Tang Dynasty, and it can be regarded as extremely advanced shipbuilding technology in the world!

There are more than a dozen types of vehicles and ships, and double-vehicle ships and four-vehicle ships are common small and medium-sized combat vehicles and ships.

And this kind of river naval warship is mostly imitating sea loach, that is, fish-shaped warships. In addition, the river ships are made by taking the advantages of various types of warships such as double cars, ten boats, and anti-sand flat-bottoms, which are mainly used for river defense and deployment.

Therefore, there is this kind of multi-pulp boat with the bottom of the lake boat, the cover of the war ship, and the bow and tail of the sea ship. With 58 oars alone, it can carry 500 soldiers. The most important thing is that the ship deck is tiled, and there are padlocks on the side, if necessary, it can be connected with the warships next to it in a short time, forming a combined chain of warships, and the connection of multiple warships will be like a city on the water, even the army can ride on the prancing horse to charge on the ground as if walking on the ground.

This warship structure still benefited from the Battle of Chibi in the late Han Dynasty, although the tactics of the serial warship were broken in Chibi, but this idea left inspiration for future generations.

Although there were no large-scale water battles during the Dahua Empire, some people put forward an advanced concept of water warfare, that is, chain ships!

By connecting enough heavy warships side by side and crossing the river, and using cladding as a support connection, you can quickly build a long bridge over the river for the infantry and cavalry to pass quickly, so as to achieve the purpose of surprise attack!

At first, this idea was considered nonsense, but there were always people who were willing to try it, and even poured a lot of human and financial resources into it. In the end, this thing was really done! When it was time to show the results, the emperor himself came.

Hundreds of heavy warships lined up on the river, and after connecting the cableway, they connected the land on both sides of the Yangtze River in just half an hour, and provided a light cavalry to quickly cross the Yangtze River to the opposite bank!

This move won the praise of the emperor.

However, it was not long before more advanced and specialized light ships were built on the basis of this idea and conception! Fortunately, heavy warships still have good uses, such as the advantage of a wide deck, suitable for transporting or storing large equipment and large quantities of supplies. Gradually, this heavy warship became a military transport ship on the river.

It was not until later, when the nations were in strife and the world was in great war, that under the division of various countries, such heavy warships were either destroyed or dismantled, and there was not much left.

"I heard that when Wang Kuian took over the port of Xiongzhou, he seized eight vehicles and ships, and then transformed them into ordnance ships, and named them Chongshou! That is, last month, he severely defeated the Qingzhou sailors!" Liu Tingyu could feel the heaviness of this deck when he stepped on it, and it was completely made according to the level of sea ships. Although the deck is stable, the protective plates, angles of attack, and the giant ordnance at the bow of the ship are installed, which increases the weight of the entire ship, making the draft of the board too heavy, which is not conducive to driving in excessive wind and waves.

Therefore, during the rainy season, or when the southwest wind prevails, it is not safe for such boats to travel!

"Oh my God!" ......

The curtain was lifted by several shipwrights, and the hidden weapon of the killer was finally revealed. The shape of the giant bow and crossbow was enough to shock everyone present! Even the trough commander and these boatmen who had seen it several times could not help but be shocked by this huge structure!

A boatman stood beneath a massive crossbow and still had to look up.

Real crossbow also. Take the mountain mulberry as the body, the sandalwood as the bow, the iron as the gun chamber, the steel as the machine, the hemp rope as the string, and the silk as the string. The maximum firing range is more than two hundred and forty steps. This is the bed crossbow.

The bed crossbow first appeared in the Spring and Autumn Period and the Warring States Period, and was launched by a winch, with a long range, but poor accuracy, and the tactics of large-scale salvo fire were generally adopted.

The large-scale popularization of bed crossbows was in the Han Dynasty.

The bed crossbow is called the cart crossbow in the north, but in fact, the use of this giant crossbow is more common and common in the north than in the south.

In the vast southern part of the country, this large area of the Gobi Desert is almost a flat river, which is very suitable for cavalry movement, so it is also very suitable for transporting large siege equipment, and the crossbow is one of them.

When Emperor Wencheng of the Northern Wei Dynasty, it was recorded that the troops of the three provinces of Yuanhe were stationed in Monan, "the city placed 10,000 people, and gave 12 beds for strong crossbows".

In the Tang Dynasty, this kind of crossbow was called "car crossbow", and after the Song Dynasty, it was commonly called "bed crossbow". The bed crossbow was greatly developed in the Song Dynasty.

One of the most famous things is that the bed crossbow played a great role in the battle of Lanyuan in the first year of Jingde.

At that time, the marshal of the Liao State, Xiao Tzulin, waved his troops into the Yuanyuan, and the Song army across the river, during the inspection, the Song army on the opposite bank caught the opportunity, with a kind of car crossbow on the other side of the river to ambush it with a long shot, did not expect a fatal blow. And because of this, the Tanyuan Alliance was promoted, which brought peace to the Northern Song Dynasty for sixty years!

It is reported: "The bed crossbow, the divine arm bow, the strength of a man can win 800 catties, the shooting can reach 500 steps, and the real army is also a sharp weapon." ”

Shooting from a distance across the bank, several times the range of an ordinary archer, this is the power of a giant machine crossbow.

The most important thing about the crossbow is its mobility, which uses oxen to pull the vehicle and move the crossbow transport to the necessary position. In terms of shooting, it also pursues greater lethality! In particular, it will have a great threat to the cavalry, because the horses will also feel fear when they see such a terrifying lethality! Therefore, the Northland cavalry will also set up horse helmets for horses to block the horse's line of sight.

Then the machine crossbow in front of you, both in its construction and its size, is far superior to an ordinary car crossbow.

The frame is like a bed board, and it does not have a curved bow hook like a common ringer, but a square wooden frame, which is fixed with steel blessings and casts, and then there are rows of bones and tendons with strained roots.

This is a standard eight-strand bed crossbow, but its size is several times larger than a normal eight-strand bed crossbow!

And the most powerful thing about such a powerful killing weapon is that it can be controlled by only one person.

Liu Tingyu walked over slowly, looking at such a huge machine: "This is the final machine?"

"Yes. The tank commander explained: "It was originally installed on both sides of the ship, so the draft was too heavy and the speed was reduced, so we restructured, leaving only this one, which should be enough, and the others have been dismantled." In addition, the base has been modified so that it could not be rotated too much before, but now it has a card slot installed and can be rotated to this angle!"

He pointed to the card slot, and Liu Tingyu nodded.

Then the trough chief tapped the copper pipe next to it, as if to send a signal. Then I heard a voice from the brass pipe: "Moo......"

"Cow?"

The trough chief nodded: "Yes! This kind of machine crossbow is strong, the method they use is to use people to rotate, like pushing and grinding, but it takes a strong force of nine people to do it, after we refit, the boat will be lighter than before, so we use oxen to strength, which is faster, and more convenient and labor-saving." ”

Liu Tingyu nodded.

The practice of the crossbow in the north is also to use oxen to pull the energy, so the transportation of the crossbow will also use ox carts to transport, which is also the best use of the material and saves the cost to the greatest extent.

This is the first time that a cow has been used on a boat, because after all, the ship is not on land, so it is inevitable that there will be a feeling of bumps, and I don't know if the oxen will be able to adapt to it.

As if seeing Liu Tingyu's worries, the trough chief said: "No problem, these cattle have been carried on the river many times before, and they are already used to boating!"

"Well, how many cows?" asked Liu Tingyu

"Three cows!"

The power of three bulls!
