After more than 20 days of tossing, everything that should be gone is gone, and what should be come is coming. The pacification division, the transfer division, the criminal department, the liquidation division, the capital court and the general bureau have all been transferred to Qiongzhou, and now only the remaining personnel of the internal government and the Chinese army and the various divisions to deal with the aftermath are left, and the noisy government is much quieter than usual, and Zhao Yu is rarely idle to think about things. To defend Qiongzhou, it is necessary to build a strong navy, which is something that Zhao Yu decided to go to Qiongzhou when he decided to go. Now that there are ships and soldiers, there are still no bottom in his heart whether he can hold it.

Zhao Yu knew that after Kublai Khan captured Jiangnan, he controlled more resources, and had the ability to form a large army to launch an expedition at any time, and he launched two wars against Japan in history, dispatching thousands of warships and 100,000 soldiers, of course, this was after the Battle of Yashan completely eliminated the Song Dynasty's government-in-exile. But if he fails to die in the cliff as he wished, it is likely that these powers will be used on his own body instead.

Limited by the resources of Qiongzhou, Zhao Yu knew that it was impossible for him to build a naval army that could match the number of the Yuan Dynasty, and he could only find a way to defeat the quantitative advantage with a qualitative advantage. With his understanding of this period of history, the Yuan army will launch a battle to attack Qiongzhou next year to cut off the escape of the Song Dynasty ******, so there is not much time left for him, and it is urgent to raise the combat effectiveness of the naval army to a level in a short time.

Modern people understand that the Mongols have developed the tactics and weapons of the cold weapon age to the extreme, and the only way to completely defeat them is to develop hot weapons. The hot weapon originated at the turn of the Song and Yuan dynasties, but it took hundreds of years of development to be perfected and completely replaced the cold weapon. Zhao Yu is not stupid enough to think that he is really a god, and he can complete the leap of hundreds of years, and cultivate the science and technology tree as high as Mount Everest.

In his previous life, Zhao Yu thought that it was very easy to build a primitive iron-hulled ship, but he did not know how difficult it was when he came to 800 years ago. First of all, there is no modern machinery, and it can only be done by hand; Even if you find a craftsman. However, it is still a question whether the most basic materials needed can be used; Even if you overcome many difficulties to build ironclad ships and equip the army, how can you drive them? Wouldn't it be funny to use oars and sails to drive.

And even if all difficulties have been overcome and military modernization has been achieved, it is tantamount to handing over a running train to a driver who can only drive a large car, and the result will be the same disaster. Cranky thinking and counting on unreliable God are in vain, thinking that now that I have embarked on the road of no return, I have pulled these tens of thousands of people into the water, Zhao Yu feels that he will not treat me at the right time. We must come up with a workable solution to the current crisis......

"Based on the status quo, fly over development!" Zhao Hao suddenly laughed, this sentence was written on the walls of the streets and alleys in his previous life, he thought it was very funny at the time, but now that he thinks it makes sense, maybe this is called a crisis!

Warships are the carriers and platforms of naval operations, and their quality is related to the success or failure of naval warfare, which is also the field that Zhao Yu is most familiar with. So he decided to start by rebuilding the ship. Although the structure and structure of ancient and modern warships are very different, they are the same, and the principle is still the same, especially since he has many years of experience in making ancient ship models. I still have confidence in this aspect. Since Zhao Yu crossed, he has always had a soft spot for turtle boats after experiencing two distress encounters, so he wanted to use it as a blueprint to create a Great Song version of turtle boats.

But Zhao Yu also faced a problem of time, he was an experienced engineer in his previous life. Know that a new ship takes a long period of time, even years, from design and finalization to manufacturing and sea trials. Now I have a model of a turtle ship. It's made to scale, and you can skip the design process, but it still takes time to completely build a new ship, especially in the current era when the manufacturing technology and methods are still all manual, so it is more appropriate for him to modify the existing ship.

Now Zhao Hao has a lot of ships on hand, and it is no longer the time when he was worried that he would not be able to take away his own little people when he was in Jiazi Town, and after arriving in Guangzhou, he confiscated and seized a number of ships, and now there are more than 700 ships in size, of course, there are many civilian ships. However, the hulls used by civilian ships and warships in this era are basically the same, only the superstructure and configuration are different, and they can even be used without modification, even in the naval army under the command of the imperial court, there are many requisitioned civilian ships and merchant ships looted in Quanzhou as warships.

The warships owned by the Marshal Army can basically be divided into three categories: sea combat ships, inland river combat ships, and river and sea war ships, among which there are sea falcons, building ships, ship ships, squid boats, sea boats, multi-oared boats, multi-oared flying river boats, red horses, white harriers, thousand stone boats, Ge ships, horse boats, loach ships, and other warships, as well as some special ships such as car ships, bottomless boats, and fire boats. Similarly, these boats are not all used to transform into turtle boats because of their different uses and structures.

Zhao Yu first expelled the special-purpose ships, followed by the thousand-stone ships and sea ships, and due to the changes in the form of water warfare in the late Southern Song Dynasty, all the warring parties focused on the taller ships in order to carry more troops and increase the ability to collide. But the size was too large, which reduced the maneuverability and speed of the ship. The battle they faced was based on Qiongzhou to attack and defend, and the turtle ships were based on surprise attacks, but strong mobility was necessary, so they could only abandon these large warships. After several screenings, Zhao Hao only had three alternative ships left on hand:

One of them is the ship. It is covered with raw cowhide, the two compartments are empty, there are crossbow windows and spear holes on the left and right, so that the enemy can not be close, the arrow stone can not be attacked, and the speed is fast, and the speed is fast. It can be seen that the warship is the most similar to the turtle ship, with 'armor' made of cowhide on its back, powered by oars, and arrow windows on all sides for attack. And it is fast, with surprise attacks as the main mode of combat. However, due to the emphasis on ship mobility, most of the ships are small warships with limited carrying capacity;

The other is a multi-oared boat. Its style is the bottom of the lake boat, the cover of the warship, and the bow and tail of the sea ship. It is characterized by a shallow draft, which is claimed to be transportable in a foot of water, and can be widely used in coastal and inland waters. Then there is the advantage of fast speed, regardless of the wind, and the reverse is as fast as flying.

Then there are the sea boats, which are tall, have a deep draft and a large carrying capacity, and can carry more soldiers, weapons and necessities...... (To be continued.) )
