In the Bohai Sea, the river flows into the sea, a large ship more than 20 meters long sails into the port from a distance, the sea water is cut from the middle, and the three-story hull brings a huge sense of oppression to the people on the shore.

Unlike the previous flat-bottomed boats, this one has a pointed bottom, which is more suitable for sailing on windy seas and is not easy to roll over. And the exterior is covered with a layer of iron sheet, which greatly improves the defense and impact power.

This was the first trial voyage of the third-generation warship of the Zhao State.

The first generation of warships of the Zhao State was ten warships bought from the Yue Kingdom, and after arriving in the Zhao Kingdom, there were only seven left, and many places were also damaged and needed to be repaired.

The second-generation warship is based on the original Vietnamese warship to improve, reinforce, enlarge, optimize the sail, so that the sail can be raised and lowered freely, adjust the direction, and add a number of masts to make the navigation more stable, and can also control the sailing speed by adjusting the number of sails.

At the same time, the ancient boat stone was replaced with an iron anchor, which was more firm when the ship was parked and avoided the phenomenon of running boats.

The second-generation warship has been greatly improved in both speed and performance.

The third-generation warship replaced the flat-bottomed ship with a pointed bottom ship, and wrapped it with a layer of iron sheet on the outside, which greatly reduced the probability of rollover when sailing at sea, and further improved the defensive and collision power.

The disadvantage is that iron sheets are expensive and easy to rust, which affects the stability of the entire ship.

Zhao Guo is still trying how to prevent the rust of the iron sheet, such as adding other metals to the iron, or spraying paint on the outside of the iron sheet. But the specific effect remains to be verified, this is the first third-generation warship of Zhao State, which has just been built, and many things are not perfect.

With Yuan Hua's shout, hundreds of catties of heavy anchors were thrown into the seabed, stirring up waves of more than ten meters, and the big ship docked steadily on the shore.

"As long as there are more than ten such big ships, even if Wu Yue's sailors are resurrected back then, the general will be confident that they will be defeated." Yuan Hua stood on the boat, facing the sea, and said excitedly.

In front of such a big ship, who would dare to say that the northerners are not good at water warfare?

Even if Lao Tzu's level is not good, just drive the boat over and hit your wooden boat, do you have a way?

What does it mean to break ten thousand laws with one force, this is it!

The only regret is that Zhao has no enemies at sea, not a single enemy, and although Yan also has ships, it has no navy.

Qi is also mostly fishing boats, and as for the naval fleet, it has long been abandoned.

However, these two countries often send some alchemists to the sea to look for sacred mountains or something.

Although Zhao Guo now vigorously supports the development of the navy, asking for money for money and people for people, Yuan Hua understands that if the navy cannot reflect its own value, these supports will disappear sooner or later, and even the navy will disappear.

The so-called value is that the benefits brought to Zhao are greater than the efforts of Zhao Guo.

In the past, although the navy had no enemies, it could be achieved through fishing, but now the fishing boats and the navy have been separated, each responsible for its own, and the navy can only be responsible for training and combat.

Unlike later generations who competed for marine resources, now there is no one competing for marine resources at all, and you have the ability to occupy the entire Pacific Ocean and no one cares.

The problem is the marine resources of this era...... In addition to fishing and drying salt, Zhao Guo couldn't do anything else.

Oil, gas? It's not as good as fish.

Maritime trade? Except for this part of the Central Plains, the others are all uncivilized savages, who will trade with you?

"It's hard." Yuan Hua sighed, and the excitement on his face was gone.

Without an adversary, it is impossible to create benefits, and even he himself cannot think of the meaning of the existence of the Navy.

But that didn't stop the group of boatwrights from continuing to get excited.

"I said that I can sail on the sea with iron sheets, and when I was in Daliang, the king told me this truth, one day, I want to build a real steel ship, instead of the small boat wrapped in iron sheets now." The young man, whose name was also Boat, said loudly.

He is very talented in physics, he has been studying at Handan College before, recently came to the shipyard to practice, and after two months, he will return to Handan College to continue his studies.

"If we can solve the problem of iron rust, it is indeed feasible." Wu Ying nodded.

He was a shipwright who came from Wu Yue, and is said to be a descendant of the down-and-out Wu royal family, who took Wu as his surname after the collapse of the Wu kingdom. The second-generation warships of Zhao Guo were designed and built by him, and Wu Ying is also one of the most skilled shipbuilders in Zhao State.

"What motivates you? In addition to the sturdiness of the warship, it also has extremely high requirements for speed. Even if your warship is a big steel ship and others are canoes, it is useless if you can't catch up with others. Ou Yeshou shook his head.

The stronger the ship, the better, but speed is just as important.

If it's just a layer of iron, it greatly increases the defense without reducing the speed too much, of course.

But if the entire warship is replaced with steel, not to mention whether it can be overcome technically, it is really built, and it can catch up with others when it is put on the sea?

Unless it is replaced with a more powerful powertrain.

“…… The problem of motivation will be talked about later, there is no way now, it does not mean that there is no way in the future, and it is ...... I'm just casually saying that the current technology is still far behind. The boat scratched his head and smiled awkwardly.

Not to mention steel, now even the problem of iron sheets has not been solved.

"It's better to tell the king about the three generations of warships first, and then apply for funds from the king, as long as the problem of rusty iron sheets can be solved, the three generations of warships are definitely the most advanced warships in the world." Wu Ying said proudly.

According to his understanding of Zhao Kuo, as long as the results are made, not only will the funds not be less, but also more will be given, and when the time comes, not only will there be money to build three generations of warships, but also be able to continue to research new warships.

"It's okay, first improve the third-generation warship and then talk about the rest, the meal must be eaten one bite at a time, and the road must be walked step by step." Ou Yeshou said, and walked towards the shore with the support of the boat.

"The old man didn't expect that one day he would be able to hope to win a fief for his children and grandchildren." Wu Ying stroked her sparse beard and said with relief.

Although the state of Chu has a water division, it does not attach importance to it, and the kings of Chu in successive dynasties have aimed to dominate the Central Plains.

Wu Ying built ships for the Chu State in Jiangdong for decades without receiving any attention, and after arriving in the Zhao State, it did not take long for him to be named Qing.

And according to the latest title system, as long as he obtains enough merits, he will be able to be the same as those generals who lead troops to fight in the future, and be crowned a marquis and obtain a fief!

"General, Handan sent an envoy here." At this time, a soldier hurried over from a distance, walked up to Yuan Hua, and said with a fist.

"Please go to the barracks first, I'll be there right away." Yuan Hua got off the boat and walked towards the barracks.
