While maintaining stability and harmony on the bright side of all countries, but all around behind, Wuhan University arrived at the seaside.
Li Jun is still the same, tall, with thick eyebrows, big eyes, red-faced skin, a mustache like a wire, and a bell-like voice.
As soon as they met, he "haha" laughed and gave Wu Da a bear hug first, and then respectfully saluted, "See the prince!"
Hug means closeness, brotherhood;
Satisfaction means obedience, which is the difference between superior and inferior.
Putting brotherhood in front of respect and inferiority, Wuhan University takes this set, and attaches great importance to friendship. Obviously, this old guy Li Jun, who has been riding the rivers and lakes for many years, is a smart person who knows the University of Wuhan.
Wu Da laughed and lifted Li Jun up, "It's been a long time since I've been stationed at the beach for a long time, don't you come here without problems?"
Li Jun smiled honestly, his big eyes narrowed into a thin slit, and he replied casually: "My lord, Li Jun was born to eat in the water. It is my honor to be able to relieve my worries for the lord. ."
He speaks rigorously, but his posture is very casual. It seems to be the same as before. There is no complaint because of Wu Da becoming the King of Beiyan. This is what smart people do.
Except for Ximen Qing, Zhang Liang, Wu Gang and other confidant generals, only Li Jun performed most satisfactorily to Wuhan University.
"That's good, it's just hard work for you."
Li Jun glared at his big eyes and said, "Where is the prince saying? I, Li Jun, is of no use on land, but since the prince, you can make me a naval captain, I naturally have to do my best to do my best. Yes. Go, Lord, I will take you on board first!"
In a few words, every sentence is about the heart of Wuhan University. Perhaps it’s a change of other people. It is bound to ask a few words about Wu University. Please take a rest for the long-distance Wu University before boarding the ship, but Li Jun did not. He knew that since the University of Wuhan was here, the ship was naturally the most concerned, so he didn't have a word of nonsense, and directly invited the University of Wuhan to board the ship.
Just such a few small things are enough to show how easy Li Jun is in dealing with people, and he can be a big responsibility.
Wu Da smiled and nodded, and walked to the big ships in front of him.
In fact, in the current year and month, the shipbuilding industry has been extremely developed, with the Song Dynasty as the most dramatic.
At the beginning of the founding of the People’s Republic of China in the Northern Song Dynasty, shipbuilding was established in Kaifeng.
Later, due to the continuous expansion of the navy, Jinming Pond could not meet the needs of shipbuilding. The Northern Song Dynasty government dug a large pond outside Xuanhuamen to draw water from the Cai River into the pond. 100 buildings used in the water war were used by the water supply army. These warships played a lot of roles in the subsequent war to unify Jiangnan.
According to the "Benji of Song History Taizu", Song Taizu reigned for 17 years, 15 times before and after "fortunately to teach shipping and observe water battles." It can be seen that the court paid enough attention to this.
But with the end of the Unification War, the responsibility of shipbuilding has changed to control the boat and water transportation. The official shipyards set up by the government on the banks of major rivers have also become the main places for the manufacture of water transport ships and official ships.
The Northern Song Dynasty official ship manufacturing has strict quota control. According to the "Song Hui Yao Collection", the official ship quota was 3,237 at the end of the Dao period. After the first year of Zhiping (1064 AD), the national water ship quota was 2,854.
However, when Jia Weijie was the deputy envoy of Jianghuai Shipping, he helped Cai Jing to build 25,000 ships without authorization for the exclusive use of Huashi Gang, and transported Taihu stones and strange flowers and woods from Jiangsu and Zhejiang to please Cai Jing and Song Huizong.
In any case, such strong data is enough to show the current prosperity of the shipbuilding industry.
Now, the ship that Wu Da ordered Li Jun to build cannot be compared with Da Song in the short term in scale, but it has improved in quality.
The reason is simple. Although Li Jun is a navy chief, he is commanding a navy, and there are other people who build the ship. A large number of craftsmen, led by Mohist craftsmen and supplemented by Wufu craftsmen, built them themselves.
Wu Da was also one of the token holders of the Mo family giant, so Mo family provided him with a certain number of Mo family children, and it was still possible to dispatch a group of craftsmen.
These giant combat vehicles are 30 feet long, have 42 wheel paddles, and are equipped with 8 wheels, each with 12 blades (blade), which is very light and agile.
Each ship needs 106 sailors, can carry 500 soldiers, and has a load capacity of more than 800 tons. It can be called a "big Mac" at sea that exceeds the number of people on all ships at present.
However, the ship is not huge enough in the water. The most important thing is to have absolute stability, especially the ship has so many tall pavilions, top-heavy, so in order to ensure that the ship will not capsize in the water, from the deck to the bottom of the ship. , Densely placed iron cast round plates with a large table top to ensure that the ship will not tip over.
In addition, the strength of the ship has also been improved. Not only the keel is installed to prop up the bottom of the ship, but also "large wax" (wood thicker than the ship's plate, similar to the fender of modern ships) is installed on both sides to clamp the whole ship, and Nail the row of nails, so that the boat can only resist wind and waves without sagging and breaking.
In this year and month, there is no engine, so in order to ensure that such a huge ship has enough power, the rudder used by the ship is a balanced rudder suitable for the whole ship to sail in shallow water and curved rivers. Part of the area of the rudder blades of this kind of rudder is before the rudder stock, and the rudder can be turned easily and effortlessly, and it can also improve the flexibility of the ship's maneuvering. At the same time, the rudder handle of this kind of rudder can be raised and lowered. When the channel water is shallow, the iron chain that can lift the rudder will raise the rudder to prevent the rudder blade from being inserted into the mud of the river bottom. When the channel water is deep, the rudder can be lowered to improve The efficiency of the rudder.
Moreover, there is a rotatable "rotating shaft" between the mast and the base, which is used for raising and lowering the mast, which saves manpower and is safer.
These are the basic structure of the ship, and its weapon system, system innovation, is even more amazed by Wu University.
Every huge ship is equipped with a three-bow bed crossbow.
Three-bow bed crossbow, also known as "Eight Bull Crossbow", the arrow is made of hard wood as the shaft and iron sheet as the feather. It is called "one shot and three swords" in the world. The bed crossbow can also fire the "stepping arrow". It’s spectacular when fired. The arrows are like javelins. They can be nailed directly into the city wall when fired at close range. When a salvo is fired, rows of stepping arrows are firmly nailed into the city wall, and the siege soldiers can use this to climb the edge. And up.
This thing is actually a siege crossbow, but it is not an ordinary siege crossbow, but an improved version of the Yin clan. When Wu Da was besieged in Sandaokou, the Yin Clan used this improved version of the siege crossbow to defeat the Liao army. superb.
These eight cattle crossbows originally required 6 people to operate, and they could only shoot 3 arrows each time, with a range of up to 600 steps, but now only two people can operate them. 6 shots in a row, breaking 1000 steps farthest!
This also means that once the enemy ship is in range, once the enemy ship is in range, Wu University can directly destroy the enemy on the road!
