Only when Zhang Jingyi was really rowing the ship and approaching this large ship, could Zhang Jingyi deeply feel the shock brought by the ironclad ship.

The huge steel hull is like a copper wall lying across the vast ocean.

The ship is fifty zhang long and five zhang wide.

Such a size is actually much more majestic than the wooden ships of this era.

Like a giant on the sea.

Of course, it is actually called an iron-clad ship, but it is not entirely cast steel.

On the one hand, it is limited by the cost! On the other hand, if all iron armor is used, the hull will be too heavy, and the steam engine used is not as powerful as such a huge horsepower to push it.

So... the method used is to create a keel with steel, and the hull is to use the best ship wood, and then wrap the wood with iron armor.

Of course, even if it is just wrapped in iron armor, this huge ship is enough to withstand the artillery attacks of this era.

The addition of wood greatly reduces the weight of the ship. At the same time, one horizontal reciprocating steam machine and 10 coal-fired boilers in the ship can provide a horsepower of 2,700.

This is of course nothing in later generations. You must know that even ordinary cars often have more than 100 horsepower. The huge steam engine and ten-seater boiler are only powered by more than a dozen or twenty cars.

Fortunately... this is in the water, and such power is enough to ensure that this ship can sail at a speed of thirty-nine miles every hour.

The ship's steel armor belt is one inch thick and the inner lining is two inches thick, which can completely ensure that in today's world, no guns can be injured.

In addition, the ship's crew requires 420 people, divided into three shifts, and activates the ship in shifts.

Of course, the most powerful thing about this ship is its firepower.

When Zhang Jingyi made a decision to build such a ship, he actually had another idea.

Yellow gunpowder has appeared, and large-scale grenades or flowering bullets have become popular on land.

But when placed on the ship, a huge problem arose because the power of this cannon is too great.

And the power means that the recoil is also extremely high. Ordinary wooden boats cannot withstand the recoil of such artillery.

Not only does it cause irreversible damage to the hull during the shooting process, but most importantly, the ship will shake violently in the sea during the shooting process, which will result in the shells being almost inaccurate during the shooting process.

However, this ship was equipped with a large number of heavy artillery on both sides and front and back, with a total of forty-nine pieces. These heavy artillery have a large caliber and huge power. Its stable hull can ensure that the ship remains quite stable during the artillery attack.

Zhang Jingyi was excited to board the deck.

A group of teachers and students came to pay their respects.

Zhang Jingyi was in a good mood today and smiled at them intimately and said, "Thank you for your hard work."

Although these three words are simple, they are very encouraging.

In fact, before the ship was launched, they started practicing day and night.

After the test was launched, due to the urgent time, Zhang Jingyi asked them to achieve initial combat effectiveness within two months.

Therefore, these teachers and students practiced almost day and night, and were extremely exhausted.

After all, the consumption at sea and on land is completely different.

The bumps on the sea are indescribable, and the mental pressure is also great.

Fortunately, the biggest advantage of the Donglin Army is its strong endurance. At this time, I heard Zhang Jing say hard work one by one, which made many people feel much more comfortable.

After all, in this era, the concept of superiority and inferiority was extremely important, and Zhang Jingyi and other princes were like mentors. The effect was doubled by a heartwarming word.

At this moment, Zhang Jing thought of something and then said, "Have the coal and supplies been installed?"

The navy's teaching team officer, Liang Wenwu, the captain of this ship, stood up.

Liang Wenwu was in the first teaching team and made many military achievements. He was sent to Lushun to learn the methods of the navy. It can be said that he almost brought this navy teaching team.

Fortunately, although all this has been from scratch, there is a good phenomenon in the Donglin Army, that is, orders are prohibited.

Therefore, although many places need to be adjusted, everyone works together, which is still smooth.

After this sea trial, almost every water teacher and student became familiar with their positions.

On the ship, although the division of labor is different from the boiler leader, to the engine leader, to the commander leader, on the ship, most of them are technical positions, and Liang Wenwu needs to master them.

At this time, Liang Wenwu stood up and said, "Everything is ready."

"Prepare to set off." Zhang Jing said in a deep voice with a sharp light: "We will wait all the way south. Target Ryukyu..."

In fact... the order has been issued secretly long ago.

Almost everyone knows their destination.

Zhang Jingyi is not going to find pirates to fight this time.

Instead, he went straight to Huanglong.

Such a huge European Combined Fleet is actually not easy to harass the entire Ming coast.

After all, there are too many people and the fleet is too large.

If you want to continue to harass and attack, then... you must have a special base.

The base of the entire joint fleet is in Ryukyu. On the one hand, Ryukyu is close to Penghu and is almost deeply embedded in the hinterland of the Ming Dynasty.

If it is set up in Luzon, Sumatra, or Japan controlled by the Netherlands, it is too far away. On the one hand, it is difficult to supply, and on the other hand, it is necessary to travel across an ocean.

And going straight through the ocean is extremely dangerous for the fleet of this era, because once a typhoon is encountered, the consequences are unimaginable.

Ryukyu is different. This is the treasure island of later countries, close to Fujian, and as long as you pass through the strait, you can walk along the entire Ming coast.

Therefore... the general base of the joint fleet must be in Ryukyu.

The place of Ryukyu was originally under the jurisdiction of the Penghu Inspection Department of the Ming Dynasty. Since the Qin and Han Dynasties, a large number of Han people have moved there. In the Song Dynasty, administrative agencies have begun to be established. Since the Ming Dynasty, although the strategy of banning the seas still falls under the jurisdiction of the Inspection Department of the Ming Dynasty, because it has eliminated the migration of ordinary people, the Netherlands has seen an opportunity to take advantage of it. So they landed on Ryukyu Island with the Spanish, established strongholds, and occupied it here.

In Zhang Jingyi's opinion, to solve the problem of countless harassment of this joint fleet, the first thing to solve is to directly cut off their rear supplies.

The best way to cut off supplies is to take Ryukyu Island directly.

In this way, this overwhelming fleet completely cut off its retreat.

Think about it... the vast majority of fleets, the rations and supplies on the ship, cannot hold on to Luzon or the Japanese island. What does this mean?

Of course... for the joint fleet, Ryukyu is very stable. On the one hand, they themselves control the sea control power. Once the Ming Dynasty's fleet goes to sea, they may be discovered at any time and then besieged by countless ships.

On the other hand, Ryukyu itself has set up countless solid fortresses, and many returning fleets are anchored.

The Ming Dynasty was too busy to take care of itself, so how could it be that he would dare to go to Ryukyu to die?

Zhang Jingyi wanted to give it a try.

This time... he used this ironclad ship as the main ship.

Along with them, Zhang San was also a carefully selected fleet of thirty carefully selected ships in Tianjin.

In this way, a fleet was formed.

Iron-clad ships are mainly responsible for opening the road and fighting, while thirty ships are mainly responsible for transporting troops.

Therefore, the dispatched personnel included more than 1,300 water teachers and students, as well as the officer teaching team led by Li Dingguo, and the first teaching team, with more than 5,730 personnel.

At this moment, a command was given.

The huge ironclad ship set out first.

Immediately afterwards, other fleets followed.

In the shimmering waves, the vast fleet of ships started to move south in a vast way.

Just standing on this deck, Zhang Jingyi still felt the scam of the ironclad ships of this era.

Although the hull is much more stable than the wooden boat with sails.

But... the huge smell of coal-fired gas, mixed with the huge noise of the boiler, especially in this cabin, the feeling... almost makes people want to spit out all their bile.

Only then did he truly feel the difficulty of the water teachers and students.

Then, he followed Liang Wenwu to inspect the artillery cabin, gunpowder cabin, engine cabin, and dining cabin one by one. Then... he looked sad every day, staying in this uncomfortable environment, fighting against the "iron armored ship".

So many times, Zhang Jingyi wanted to get off the boat and go to other sailboats, but this idea was quickly dispelled. After all, it might be bad for morale, so he had to endure it.

At this time, in the combat cabin.

The Jinyiwei had already prepared a map of Ryukyu, and marked countless strongholds in northern Ryukyu and Spain. In addition, there were a large number of strongholds and fortresses in the Netherlands in the south.

It has to be said that Spain is not bad, but in the Netherlands in Southern Ryukyu, the Netherlands obviously hoped to use the entire Ryukyu as a springboard for them to penetrate the mainland, so they spent countless manpower and material resources to operate.

After they set up the fortress, they plundered the land, killed and enslaved the local natives and Han people, planted a large amount of sugar cane here and made sugar sugar. In addition, a large number of ports were established, so the main base of the entire joint fleet was within the control of the Netherlands.

In addition to building fortresses, they also arranged a large number of troops. At first, they only guarded against the resistance of the Han people and the natives, and at the same time guarded against the Ming army of the Penghu Inspection Department. Now... because of this expedition, the troops here have doubled.

Even... Spain recruited a large number of natives from Luzon and Sumatra and other places to assist the Netherlands in defense.

It can be said that for this battle, these people almost took out all the coffin books.

Obviously, they are just trying to do a big vote.
