The steamship was launched in a lake near Gyeonggi.

Because this steam boiler was loaded on a river boat, this flat-bottomed boat, which was slowly transported by countless people in rolling logs, because it was too large, and even used the servants of the Shuntian Mansion to make them clear the way for it.

Fang Jifan and Zhu Houzhao have been waiting here for a long time.

This is a steam-wood ship, and under the current technical conditions, making an iron ship is almost a dream.

After all, the power required for ironclad ships is too great, and it is not something that can be solved by the current steam boiler.

In order to place the boilers, the ship was very large, nearly twenty zhang long.

From a distance, the hull looks long and narrow, and the top is ...... There is a chimney.

At the bottom of the boat, there is a dark wheel.

That is, it uses a steam engine to drive a dark wheel to power the ship.

This thing...... Don't look at it as just a wheel blade, but in history, there have been many detours, when people also tried to make steam ships, but at first, the manufacture was a paddle wheel, the so-called "paddle wheel" is installed on both sides of the ship outside or stern shaped like a big wheel, the paddle blade rotates to hit the water backwards, using the reaction force of the water to push the ship forward. However, the efficiency of using paddle wheels to propel is relatively low. Especially in the case of strong wind and waves, the oars often come out of the water and spin, and the boat shakes violently when driving.

It wasn't until fifty years later that people realized this huge drawback, and some people tried to improve it, and finally invented a propeller like a windmill and an electric fan blade to replace this paddle wheel, which greatly improved the efficiency of steam utilization and increased the speed of navigation.

Fang Jifan's eyes looked directly at the 'dark wheel' loaded on the stern, and he couldn't help but sigh in his heart, the so-called technological progress is actually just a process of trial and error.

From the bright chakra to the dark chakra, in fact, it only takes one thought, and the technical difficulty required is not high.

But just such a thing was delayed for 50 years, and after the dark wheel, the steamship had the possibility of large-scale application.

The design method of this dark wheel was mentioned by Fang Jifan.

Fang Jifan really didn't want his money to go down the drain, it was all money, silver spent in vain.

The boat began to be launched slowly, and then the tugboat slowly dragged the human scum Wang Bushi to the middle of the lake.

Zhu Houzhao was already dancing excitedly, and he was very happy.

This area of water has been explored, and in most places, the water depth is enough to allow such a huge ship to pass.

He dragged Fang Jifan: "Let's go, get on the boat." ”

"Isn't it dangerous?"

Fang Jifan looked at the behemoth in the middle of the lake with some worry.

Zhu Houzhao said: "You still can't trust this palace." ”

Fang Jifan's tiger body was shocked and shivered, but he was dragged onto a small boat by Zhu Houzhao, many small boats loaded with sailors and helmsmen set off together, and arrived at the scum Wang Bushi in the world, and then, people boarded the ship one after another.

Fang Jifan stood on the deck and looked back at the huge chimney.

Fang Jifan said: "How many times has Your Highness tried water?" ”

Zhu Houzhao said: "This is the first time. ”

Fang Jifan: "......"

He also thought that Zhu Houzhao had used other ships to conduct experiments before.

At least...... It's time to verify it.

At this time, Zhu Houzhao held a small flag and waved it.

Suddenly, the sailors in the distance got the order, in the boiler room, a group of sailors began to light the furnace, as the furnace burned, steam began to come out, Fang Jifan felt a slight tremor under his feet, as if he was standing under the boiling pot lid, he thought silently in his heart, nothing is wrong, nothing is wrong, the progress of mankind comes from the progress of technology, and this progress starts from our Jifan today.

What is the ...... Listen to make yourself like Tan Sitong.

Somewhat tragic.

At the bottom of the boat, the blades finally began to turn, and the whole boat slowly began to move, and it slowly began to splash in the lake.

The motivation seems to be quite sufficient.

Zhu Houzhao was already dancing excitedly, rushed to the wheelhouse, pushed the helmsman away, and happily turned the rudder, the whole hull began to tilt slightly, and the tilt began to become more and more powerful, Fang Jifan felt a force to push himself into the water, and at the moment when his face was like earth, the ship finally began to slowly stabilize again.

The ship turned its direction and continued to move slowly, and the speed began to increase, because the appearance of inertia made the ship begin to feel no resistance.

The huge hull of the ship began to move along the lake.

It wasn't until late afternoon that Fang Jifan got off the boat in a daze.

When they arrived on the shore, someone shouted: "Oh no, no, Qi Guogong fainted...... Fast...... Call the doctor. ”

Fang Jifan gasped for breath, and finally felt a little better, his eyes opened slightly, and he waved his hand: "Don't, seasickness!" ”

Zhu Houzhao was happy: "Walking in the lake, you are also dizzy, your body is ...... bones"

Fang Jifan suddenly became excited, and when he got up, he was about to pinch Zhu Houzhao's neck: "Your uncle, what are you turning around, can you drive the boat well?" ”

Zhu Houzhao snorted: "Look, everyone else is fine." ”

On the shore, there was already a group of students, carrying pens and recording data, and in the end, someone took a book and sent it to Zhu Houzhao.

Fang Jifan snatched the book and looked at it, the speed was not bad, compared to ordinary sailboats, even if it was a boat sailing along the river, the speed was nearly twice as fast.

The crew made calculations, and based on the length of the voyage, the maximum and average speeds, and the remaining fuel, they finally concluded that the ship could sail for twenty-three hours, or about five hundred and seventy kilometers, with a full load of fuel.

Of course, this is a lake, and if you drive against the water in an inland river, it will take 15 hours, about 400 kilometers. But if it's smooth...... So...... It will be possible to reach forty-one hours and eight hundred kilometers.

Fang Jifan looked at the data one by one and breathed a long sigh of relief.

There is still a lot of room for improvement, and if the ship and boilers are remodeled, it may be possible to sail for a longer time.

It would be nice to be able to make an internal combustion engine.

But immediately, Fang Jifan dispelled this thought.

With Zhu Houzhao's IQ, he can't see it in this life.

But it doesn't matter.

As long as the voyage can be guaranteed, the freshwater problem of steam sea ships ...... Can be solved......

Like what...... Steam ships can travel along the coast, in fact, in this era, most of the original ships are traveling along the coast and into the deep sea, which is too risky.

As long as there are ports built along the way, if the voyage can reach 600 kilometers, then it is enough to dock at any time for replenishment.

Fang Jifan exhaled, his eyes opened slightly: "Start improving immediately, in addition, the sea ship should be launched as soon as possible, silver, I am out, how much I want." ”

With this achievement, Fang Jifan was already satisfied.

Uncle, isn't it silver? Our successor is short of silver?

What our successors lack is women.

He cautiously raised his eyes and glanced at Zhu Houzhao.

Zhu Houzhao didn't know how to read minds, so he said happily: "It's easy to do it if you have money, in the Steam Research Institute, everyone is on standby, just wait for your words." Come, come, come, you go on the boat, continue to test the ship, see if there are any problems, where can be improved, these days, you are dying, all to this palace to die on the ship. ”

A group of students and craftsmen, where dare to slack off, busy is on the boat.

Zhu Houzhao and Fang Jifan were on the way back, and along the way, thinking that countless pieces of silver were about to be thrown into the water, Fang Jifan's heart ...... It's still a little painful, but now it'...... It seems that the light is about to be seen.

If...... When a real steamship can appear, then ...... The distance from Daming to the Golden Continent will be greatly shortened, and his father is still in the Golden Continent, but he doesn't know it......

Come to think of it.

Fang Jifan exhaled, I hope that in my lifetime, I can see each other a few times.

…………

Xingwangfu.

Zhu Houxi bowed his hand to several people with a well-behaved face: "Uncle Jingjiang is good, Uncle Liao is good, Brother Changyang is good, Brother Xingshan is good......"

More than a dozen princes gathered together, and Zhu Houxi greeted them one by one.

Zhu Youqi, the king of Jingjiang, stroked his beard and smiled: "Houxi is really a good boy."

As he spoke, he and Xingwang Zhu Youqi looked at each other and smiled.

Zhu Youqi said: "Where is it, Brother Wang is too loving, tomorrow ...... Dongcheng Theater staged "The Case of Quanmei", is Brother Wang interested? ”

The king of Changyang was young, patted his thigh and said: "Yes, yes, yes, my favorite thing to watch is "The Case of Quanmei", click it, be happy!" ”

Everyone laughed.

Zhu Youqi smiled, took a teacup, took a sip of tea, and then said: "Brother Liaowang, I am waiting for you to come this time because I want to discuss some important matters." ”

Liao King Zhu was stunned: "I don't know what to see." ”

"I heard, you still live in the Honglu Temple?" The first person who couldn't help it was Zhu Youqi, the king of Jingjiang.

When Zhu Chongzhu heard this, he immediately bowed his head and remained silent.

On the other side, Xingwang Zhu Youqi said with a smile: "This is not a long-term solution, you see, the king of Jingjiang has bought a mansion, eighty acres, and I am my neighbor; There is also the king of Changyang, the king of Youxing Mountain...... We all bought it, thinking that Brother Wang was still in Honglu Temple, those of us who were brothers, as well as these juniors, saw it in our eyes, and we were also anxious in our hearts. ”

Zhu Youqi said on the side: "Yes, yes, the prince of the palace, how can you have no fixed place, your family is young, there are more than 100 people, your age, it's okay, but you have to think about it for the son, now the price has risen again, our land, one acre has risen by more than 1,700 taels, how much is this 100 acres of land?" ”

Several other county kings also began to persuade: "Uncle Wang......"

When Zhu Chongzhu heard this, he was angry: "This king can't afford it, he can't bear this breath, this king understands it, this Xishan Jianye, His Majesty has shares, His Royal Highness the Prince has shares, and those surnamed Fang also have the courage to summon us, that is, to buy them a house, Emperor Taizu Gao's ancestral system is gone......"
