Because Yu Ming knows that in history, in 1845, there was an interesting competition held in England. They had a race between the rattlesnake propeller steamer and the Eriktor paddle steamer, of the same tonnage and loaded with the same horsepower steam engine.

The British tied the sterns of the two ships with thick cables and made them go in opposite directions. The rattlesnake's propeller spun rapidly, and the Erikto's paddle wheel violently threw water backwards. At first, they refused to give in to each other, but after a while, the "Sidewinder" towed the "Eriktor" away. This race proved the superiority of the propeller. Since then, propeller steamers have replaced paddle wheels.

Although the steam engine was not invented now, boats are rowed by manpower. But Yuming believed that as long as the same number of sailors turned the pulp. The propeller will never lose to human paddling, after all, it is better than the paddle steamer, which is far faster than human paddling.

Zhou Qiang couldn't help but be a little skeptical. Yu Ming knew that he would not fully believe it for a while, so he instructed him to make the propeller and order the carpenter to make it first, and try it on a small boat first, if the speed is really much improved, then use it on this big ship.

When Zhou Qiang heard this, he felt that this could be a try, so he immediately called several of his subordinate carpenters, and then handed them the propeller drawings drawn by Yu Ming, and asked them to immediately make two propellers that could be used in small boats.

At this time, the eldest grandson Wujian was still a little skeptical, and after stroking her hair with her slender hand, she asked softly: "Husband, even if that propeller can greatly increase the speed of the ship, this ship is also big!" Wouldn't it become a live target for the enemy's fire attack at sea? In addition, it doesn't rotate very flexibly, so it's dangerous to use it in battle! ”

Yu Ming smiled slightly: "I have already thought of this problem. In fact, this is not difficult to solve, as long as we change the ship's side and deck to iron wrapping, won't this problem be solved? ”

"Wrap the ship's side and deck in iron? Oh, my God! That's a lot of pig iron! When the eldest grandson heard this, he couldn't help but exclaim.

Zhou Qiang was even more anxious and said: "His Royal Highness King Zhou, this method of wrapping in iron sheets has actually been thought of by shipwrights before. But it has not been adopted, in addition to the eldest grandson princess said that there is a lot of iron, the cost of shipbuilding is high, there is also a serious lack of stuffing, once the ship is damaged in battle, especially after the underwater hull is damaged and enters the water, resulting in the ship sinking quickly. Purely wooden boats, on the other hand, are not in danger of this. ”

After hearing this, Yu Ming said confidently: "As long as the cabins are isolated to form several ** cabins, all the cabins are sealed with doors, and after one is flooded, all the hatches entering the cabin will be closed, and the other cabins are still intact." In this way, even if one or two cabins are flooded, the ship will not sink to the bottom! ”

The isolation cabin is a new technology in this era, and even a veteran shipwright like Zhou Qiang has never thought of it. Yu Ming's reminder suddenly made him suddenly brightened. There is a feeling of brightness in the eyes.

After thinking about it for a while, he immediately said ecstatically: "His Royal Highness King Zhou, your proposal really made Zhou Mou Mao stunned!" The subordinates must apply the propellers, isolation cabins, iron wrapping hulls and other technologies you mentioned as soon as possible! It's just ......"

Zhou Qiang said cautiously: "In this way, I am afraid that the cost will be greatly overrun, and the copper coins drawn by the princess are afraid that they will not be enough!" ”

Yu Ming didn't care about it when he heard this, shook his head and said: "Lord Zhou, you don't have to worry about money, I will let Wujian pull out enough money to give you enough money." But the scale of our shipyard is also small! Just because of the construction of this large sailing ship, other shipbuilding projects had to be suspended. It may not have a big impact! Didn't you mention the expansion of the shipyard to Lord Du? ”

When Zhou Qiang heard this, Fang Chang sighed: "His Royal Highness King Zhou, my brother and I can't wait to expand the shipyard!" But now there is a shortage of manpower. Even if you have money, you can't improve the efficiency of shipbuilding. Because skilled craftsmen are like this, if it weren't for my brother, I urgently mobilized a group of villagers from my hometown to Liaodong. I'm afraid we won't be able to build even a medium-sized warship. But for this matter, my brother was abused by several elders of the clan, saying that he actually abducted the clansmen to suffer outside the customs......"

Yuming didn't expect that the Zhou brothers would also suffer so many grievances, and he was also a little emotional.

After he took a deep breath, Fang discussed with Zhou Qiang about the construction of this giant sailing ship and the difficulties that the Liaodong shipyard was currently facing, and Fang returned home with his eldest grandson, Wuji.

He already planned to convene an enlarged meeting to concentrate on resolving the current problems and contradictions in eastern Liaoning. Otherwise, there will be a lot of friction and conflict within ourselves in the future.

……

On September 10, the twelfth year of the Great Cause, Yuming held a meeting of all his high-level personnel in the palace of King Zhou in Liaodong City.

The meeting was held in an ordinary hall in the palace, and there were many people who participated, not only did the eldest grandson Wuji rush over from Silla, but even the two ladies of Red Sleeves and the eldest grandson Wuji were also notified to attend. The county guards of the six counties of Liaodong and the commanders of the Ninth Army were all present. Only Li Xiuning was assigned a special assignment to accompany Yang Luoqi to Pyongyang to inspect local affairs. so as to take the opportunity to separate this princess, lest she inquire about the content of the meeting in Liaodong City.

Yuming also has a headache for Yang Luoqi now, and it is inappropriate to get rid of her, leaving her worried that Liaodong's secret will be discovered by her. But it was difficult to lock up this princess, so she had to order several ladies to take turns to accompany her to wander around, and at the same time ordered strict control of everyone Yang Luoqi might come into contact with. According to Yu Ming's meaning, she can only let her fiancée meet the person that Liaodongjun wants her to meet.

Yuming originally thought that Red Sleeves, Li Xiuning, and the eldest grandson Wujian would be furious when they learned that he was engaged to Yang Luoqi. But to his surprise, the woman didn't have the angry scene he imagined, but just counted him down a few words and asked him not to be careful.

And what made him feel the most strange was that the relationship between Red Sleeves, Li Xiuning and the eldest grandson Wujian was not harmonious before, although he did not dare to say that he was like an enemy before. But now after the woman arrives in Liaodong, she eats, sleeps, and walks together, often hooking shoulders and arms, talking and laughing, like sisters.

What is the reason for the sudden improvement of the relationship between this woman? Yu Ming was puzzled.

He didn't know that this was the result of the eldest grandson Wuji's elder brother, the eldest grandson Wuji, after learning that Yang Guang had given his daughter Yang Luoqi to Yuming in marriage, and then told her.

The eldest grandson Wuji once specially persuaded his sister: "Wuji, our Da Sui is a husband and a woman, and a woman has a woman's virtue!" There are seven ways to divorce a wife, among which jealousy is to leave a wife! Look at how a pampered and proud woman from ancient times to the present has a good end? Even the queen is like this. Empress Lu of Liu Bang, the ancestor of the Han Dynasty, was in power at that time, but in the end she ended up with a tragic ending. ”

"According to his brother, Yuming's future will definitely be much greater than that of his father Yuhua and grandfather Yushu! Those members of the royal family, ministers of the DPRK and China, border generals, celebrities and gentry...... Which one is not a wife and four concubines? Those wives who take the initiative to persuade their husbands to take concubines, and even introduce concubines into the house on behalf of their husbands, who does not praise her for being virtuous and virtuous, and treating others generously? You don't want to have a reputation for jealousy, it won't be worth the loss...... Men really want to be careful, but women can't stop it if they want to......"

"Sister, look at the current situation, although our eldest grandson family is also a Guanlongmen valve, it is only a small family, not to mention compared with the Yu, Dugu, and Yuan families, even compared with the Li family. You can marry Yu Ming, this is also because he is a man with deep affection and righteousness, not how good your conditions are......"

Eldest Sun Wuji's eloquent words continued to echo in Eldest Sun Wuji's mind: "Sister, if Yu Ming first has a relationship with Li Xiuning or Red Sleeves, it is really difficult to say whether he will marry you." At present, Princess Luo Qi has been married to Yuming by the saint, as a princess, she is one of the four beauties in Luoyang, regardless of status, appearance and temperament, she is much stronger than you. If you have a hard fight with her, it's a question mark whether you can keep your status as a wife......"

"But you don't have to be alarmed, I see people very accurately, Yuming is a person who values love and righteousness, and he really loves you. Now that you have given birth to your daughter Shanshan, in the future, as long as you regenerate your whole heart to assist him and serve Ying Xiang. Even if Princess Luo Qi is more beautiful than you and her status is more noble than you, your wife's position is untouchable, and no one will want to snatch it. ”

"But you must remember: pantothenic acid and jealousy can only be thought about in your heart at most, and you must not speak ill of Princess Luo Qi because of this, and even be jealous and quarrel in front of Yuming. In my opinion, Ah Nian is young and handsome, and he is both martial, and now he has controlled the entire territory of Liaodong, with 100,000 troops, and he may have to march into the Central Plains, or even become the emperor...... There must be a lot of women who marry into the door. You might as well have a good relationship with Princess Luo Qi, Miss Li and Senior Sister Red Sleeves, and get closer to them more, so that you can get along well in the future. And Yuming sees that you are so harmonious, and his thoughtfulness and generosity towards you will only be more grateful, respect you more, and will only be better to you! ”

The eldest grandson Wujian was slowly sitting down with the jade arm with red sleeves at this time, and the two daughters seemed to be like sisters, but the pain in her heart was known only to herself.

She couldn't help but sigh secretly, who is a wife who doesn't expect her husband to go out of the land and become an official and become a knight, so that his wife will also have a light on her face. But once the husband has a career and his status rises, he has to share his husband with other women, which is really a "repentant husband and a proper king", and there will be gains and losses.

This meeting, which was related to the fate of Yuming and a group of followers, was held in such a simple and quiet hall......
