The officials on the dock were as nervous as Yang Hao as they looked at the ships slowly sailing in Jishui.

When the three sails were deployed, the ship's speed increased dramatically, and it went up against the current.

Yang Hao's eyes suddenly lit up when he saw this, this speed is many times happier than the previous warships of the Qi Kingdom, it is just a good phenomenon, as long as there are no other problems, at least this speed is enough for ocean voyages.

After the boat traveled for almost half an hour, it slowly leaned towards the dock, and Shi Xi, as the person who tested the boat, came to report to Yang Hao.

The excitement in his heart even surpassed that of Yang Hao, such a ship with excellent performance should be born to crisscross the ocean.

Just such a simple test does not verify the overall performance of this boat.

Yang Hao asked Shixi to steer the boat and go to the sea to test, if it was within a month, he would be able to complete all the tests.

This means that the Ministry of Industry can produce such ships on a large scale, and the tonnage will be many times larger than this test ship.

Thanks to the excellent natural environment in ancient times, the country of Qi did not lack excellent timber needed for shipbuilding.

As long as the imperial court is willing, it can form a huge naval division no less than the army, but this idea can only stay in the imagination stage.

After all, the cost of building a well-developed navy is simply not comparable to that of an army of the same size.

There is an old saying that 10 years of the army, 100 years of the navy.

This sentence was vividly embodied in the Age of Discovery, when the Netherlands, Spain, and Portugal built a powerful navy after a hundred years of maritime trade accumulation.

Once upon a time, Britain began to rise, relying on a powerful navy to establish a colonial system around the world, and this process, from the Battle of Gravoline to the victory of the Seven Years' War, took two hundred years, which shows the difficulty of naval construction.

Even if the Qi State is really willing to spend money to build a large number of sophisticated warships, the navy is still a long way from forming combat effectiveness, just like the original Manchu court, the navy seems to be powerful, but in fact it is vulnerable.

What Yang Hao wants now is not to dominate the ocean, he just needs to be able to sail the ocean and go to the other side of the sea to bring back what he needs.

As for colonizing the world, even if he was given another hundred years, he estimated that he would not be able to do such a terrible thing at all.

The Eurasian continent is big enough, as long as you manage your own one-third of an acre of land well, it will be a great cause.

It wasn't until the sail warship was far away that Yang Hao returned to the city with some unfinished business.

It's just that the excitement in his heart is not something that only idle people can experience.

America, that is a key link that can change the level of civilization in the Qi country.

As long as you have corn, peppers, potatoes and other good crops, you can do whatever you want at that time.

As for saving the Americans, Yang Hao didn't even have a thought, in his opinion, the Americans were a strange race that had nothing to do with him, and their life and death were not within his consideration.

If they are good at talking, and honestly trade with their own fleet, that is, friends come and have good wine, and if they use any crooked brains, he will not mind following the example of the white skins of Europe in later generations and killing him with rivers of blood.

According to the normal historical development trajectory, the Americas are now extremely backward, and perhaps the degree of civilization is even inferior to those Yue people in the south of the Yangtze River.

When there is food, there will be a massive population, and with a huge population and food as a confidence, he will be able to form a larger army, and he can occupy every piece of land within his sight for Yang Hao.

Yang Hao seemed to have seen the hope of unifying the whole country at this time.

This kind of reunification is not the unification of the Central Plains as understood by the Qi people, but the territory of the homeland of more than 9.6 million square kilometers.

This is a knot that Yang Hao has never been able to let go.

Coming to this era, he has worked hard for more than ten years, and so far he has not even occupied the traditional Han land, which he has great regrets.

But the moment the warship was launched, Yang Hao's ambition was ignited again.

On this day, Yang Hao's concubines were surprised to find that Yang Hao seemed to be more than ten years younger, whether it was the amount of food or some indescribable things, their king seemed to have endless energy.

Yang Hao, who was in a good mood, took a two-day vacation for himself for the first time, and took his concubines and younger children to a two-day tour around Chang'an City.

Today's Chang'an City, after more than ten years of construction, has a lot of places worth playing.

Yang Hao had a lot of fun, as if the pressure of more than ten years had disappeared without a trace at this moment.

At that time, under the beautiful scenery of the green grass, countless bones were buried.

The original enemy has long since turned into a handful of loess, which has become a nourishment for the earth.

Looking at the Chang'an City under the sunset, Yang Hao watched quietly for a long time.

The peasants returned to the city tiredly, and the starting point of Chang'an at night was bright, and the smoke curled up, looking so peaceful and quiet.

It's just that when most people are eating dinner and talking about their parents' shortcomings, the Academy of Sciences located outside Chang'an is brightly lit.

These Qi scientists, who don't listen to what is going on outside the window and only want to engage in research, have been greatly stimulated after the sail battleship is launched, how can these guys in charge of different research directions endure being subservient to others.

Each research group is holding back their energy, hoping to prove that they are not squandering wine bags and rice bags with their own efforts.

It's just that most of the researchers of the Academy of Sciences are fighting collectively, and only the prisoner of Dongmen, who studies the bridge, is still fighting alone.

He was not surprised that the sail battleship could be launched smoothly, and in the past six months, he had seen with his own eyes how crazy Yunfeng was, making such a large number of calculations.

Although Yunfeng was two years younger than him, he looked ten and a half years older than him, and he already had half gray hair at a young age.

Yun Feng's spirit deeply inspired him, and he believed that as long as he worked hard, he would definitely reap the rewards.

In the past six months, except for the occasional intersection with Yunfeng, he was completely out of a state of retreat, and it took him a month to learn all the primary schools of Qi State, and even the knowledge of intermediate schools, by looking up information, he could also figure out a general idea.

Coupled with his own intelligence, he is now no less knowledgeable than an ordinary person who has studied for several years.

With this theoretical knowledge as a reserve, it has played a double effect on his bridge research work.
