When the countries remained stable and peaceful on the surface, but behind the scenes, they were all ready to move, Wuda arrived at the seaside. Pen, fun, and www.biquge.info

Li Jun is still the same, tall, with thick eyebrows, big eyes, red skin, a mustache like wire, and a voice like a bronze bell.

As soon as they met, he laughed "haha" and gave Wuda a bear hug first, and then saluted respectfully, "See the prince!" ”

Hugging means closeness and brotherhood;

Bowing means being submissive, but there is a difference between superiority and humility.

Put brotherhood in front of respect and humility, Wuhan University eats this set, attaches great importance to friendship, it is obvious that this old guy Li Jun, who has been galloping the rivers and lakes for many years with a rough appearance, is a smart person who is thick on the outside and fine on the inside, and knows Wuhan University very well.

Wu Da laughed and helped Li Jun up, "I haven't seen you for a long time, I've been stationed on the beach for a long time, don't you come unharmed?" ”

Li Jun smiled innocently, his two big eyes narrowed into a slit, and he replied very casually: "Lord Wang, I, Li Jun, were born to eat in the water, and it is my honor to be able to relieve my worries for the prince." ”

The words are clear-sighted, but the posture is very casual, it seems that it is still the same as before, and there is no problem because Wuda became the king of Northern Yan, this is what smart people do.

In addition to Ximen Qing, Zhang Liang, Wu Gang and other henchmen, only Li Jun's performance was the most satisfactory to Wuda.

"That's good, it's just hard for you."

Li Jun stared at his big eyes and said, "What is the prince talking about?" I, Li Jun, are of little use on land, but since you have appointed me as the Governor of the Navy, I naturally have to do my best. Let's go, lord, I'll take you on board first! ”

A few words, every sentence has talked about Wu Da's heart, maybe he has changed others, he is bound to say a few warm words to Wu Da, please take a short rest before boarding the boat, but Li Jun did not, he knew that since Wu Da came, the most concerned thing was naturally the boat, so he didn't have a word of nonsense, and directly asked Wu Da to get on the boat.

Just a few small things are enough to show how easy Li Jun is to deal with people and things, and he can take on big responsibilities.

Wu nodded with a smile and walked towards the big ships in front of him.

In fact, in the current era, the shipbuilding industry has been extremely developed, with the Great Song Dynasty as the most dramatic.

At the beginning of the founding of the Northern Song Dynasty, a shipbuilding service was set up in the capital city of Kaifeng, and it began to be called a shipbuilding service, which was responsible for building and repairing ships and teaching water warfare.

Later, due to the continuous expansion of the navy, the Jinming Pond could not meet the needs of shipbuilding, and the government of the Northern Song Dynasty dug a large pond outside the Xuanhua Gate, leading the water of the Cai River into the pool, and 100 building ships were used in the water war, which were used by the water supply army. These warships played a lot of roles in the later war to unify Jiangnan.

According to the record of "Song History Taizu Benji", Song Taizu reigned for 17 years, and 15 times before and after, "fortunately taught shipping affairs and watched water battles". It can be seen that the imperial court attaches enough importance to this.

However, with the end of the War of Unification, the responsibility of shipbuilding changed to control the ship and transportation. The official ship yards set up by the government along the main rivers have also become the main places for the manufacture of water transport ships and government seat boats.

The Northern Song Dynasty official ship manufacturing has a strict quota control, according to the "Song Hui to Compile Manuscripts" records, to the end of the Dao year, the official ship quota is 3,237, after the first year of Zhiping (AD 1064), the national quota of Cao ships is 2,854.

However, when Jia Weijie was serving as the deputy envoy of Jianghuai shipping, in order to echo Cai Jing, he built 25,000 ships without authorization for the exclusive use of Huashigang, and transported Taihu stones and strange flowers and trees from Jiangsu and Zhejiang to please Cai Jing and Song Huizong.

However, in any case, such strong data is enough to show the prosperity of the shipbuilding industry at present.

And now the ships built by Li Jun under the order of Wu Da will definitely not be comparable to the Great Song Dynasty in terms of scale in the short term, but they have reached a higher level in quality.

The reason is very simple, although Li Jun is the governor of the water division, he commands the water division, and there are other people who build the ship, which is led by the Mo craftsmen and supplemented by a large number of craftsmen from the Wufu Province.

Wu Dahao is also one of the holders of the Mo family giant token, and Mo Lao has provided him with a certain number of Mo family disciples, and it is still possible to transfer a group of craftsmen.

These giant combat vehicles are 30 zhang long, with 42 wheel oars, and 8 wheels next to them, each with 12 blades (blades), which is very light and agile.

Each ship needs 106 sailors, can carry 500 soldiers, and has a carrying capacity of more than 800 tons, which can be called a "giant" at sea, surpassing the number of people carried by all ships at present.

However, the ship in the water, is not huge enough, the most important thing is to have absolute stability, especially there are so many tall pavilions on the ship, 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 with a large table of iron cast round plate weight, to ensure that the ship does not capsize.

In addition, the strength of the ship has also been improved, not only the keel is installed to support the bottom of the ship, but also the "big wax" (wood thicker than the ship's plank, similar to the fender material of modern ships) is installed on both sides to clamp the whole ship, and the row of nails is nailed, so that the ship can only resist the wind and waves without loosening and breaking.

In those days, there were no engines, so in order to ensure that such a huge ship had enough power, the rudders used were balanced rudders suitable for the whole ship to sail in shallow and crooked waters. This rudder has a part of the rudder blade area before the rudder rod, which can be used to turn the rudder lightly and effortlessly, and also improve the flexibility of the ship's maneuvering. At the same time, the tiller of this rudder can be raised and lowered, when the channel is shallow, the iron chain that can control the rudder can be lifted to prevent the rudder blades from being inserted into the river bottom mud, and when the channel is deep, the rudder can be lowered to improve the effectiveness of the rudder.

Moreover, there is a "rotating shaft" that can be rotated between the mast and the base, which is used for the rise and fall of the mast, which is both manpower saving and safer.

These are the basic structures of ships, and the innovation of their weapon systems and systems is even more surprising to Wu Da.

Each huge ship was equipped with a three-bow bed crossbow.

Three-bow bed crossbow, also known as "eight-cow crossbow", the arrow is made of hard wood as the arrow shaft, the iron piece is the feather, the world is known as "one gun and three sword arrows", the bed crossbow can also be fired "stepping arrow", when it is launched, it is magnificent, the arrow is like a javelin, the close-range launch can be directly nailed into the city wall, when the salvo is fired, the rows of pedal arrows are firmly nailed into the city wall, and the siege soldiers can climb up by this.

This thing is actually a siege crossbow, but it is not an ordinary siege crossbow, but it has been improved by the Yin clan.

These eight-bull crossbows originally required 6 people to operate, and they could only shoot 3 arrows in a row each time, with a range of up to 600 steps, but now only two people are needed to operate, one person can wait and see, one person can fire, and each time it can fire 6 arrows in a row, and the farthest break is 1000 steps!

This also means that once the enemy ship enters the firing range, Wuda can directly destroy the enemy on the road!
