Iron Dynasty

One second of genius remembers, to provide you with wonderful novel reading.

The wound on the **** is still aching.

Bei Shan's memory of the humiliation suffered during the Battle of Jizhou is still fresh. The last fiasco caused the blood wolf tribe to be destroyed by more than half, and the guilt of losing Shanhaiguan made his father Khan furious.

Had it not been for his mother to plead with the leader of the Tula tribe, he could only use his life to atone for his sins instead of cutting off the three fingers of his left hand.

After that, he was even more ordered to surrender the power of troops. Now he can only live in Korea and supervise the vassal state in name.

"Fine, it's not his fault. The Qi king of Great Yu is not so easy to deal with." Bei Shan forced down his anger, his eyes rolled, and with his sensitive sense of war, he felt that a war seemed to be Getting closer.

Upon hearing this, the King of Korea shouted to Park Zhenghao: "Bei Shantai kindly forgave you, and I am not thankful for retreating."

Lieutenant Jin suddenly kowtowed, and Park Zhenghao also leaned over to kneel.

Turning his head and looking at Bei Shan's thoughtful look, King Goryeo lightly breathed a sigh of relief. He really didn't want to punish his generals because of this incident. After all, they were also his generals anyway.

At this time, Bei Shan looked at the southern sea and faced King Goryeo and said, "How long does it take to depart from here to Dengju?"

"Going back to Taiji, here is very close to Dengzhou, it takes a day to reach Dengzhou by boat." King Goryeo said cautiously.

"One day?" Bei Shan's eyes sparkled with a strange light, and he then asked: "How many soldiers can your navy transport at one time?"

"It's okay for 10,000 people. [] "The King of Korea suddenly had a very bad feeling.

Nodding lightly, Bei Shan said: "Too little, from now on, you Korea will use all means to speed up shipbuilding and prepare for the Golden Horde to send troops to Great Yu."

King Goryeo's heart trembled, and he asked nervously, "Is Tian Khan preparing to go south?"

"The north is getting colder and colder. Our cattle and sheep will freeze to death every year. Rehabilitation has become bullshit, and our people will starve to death if they don't go south." Bei Shan sneered.

Although his aggressive advancement led to the failure in Jizhou and the loss of Shanhaiguan, he has been pushing the Golden Horde to go south. Now the head of the tribe on the grassland finally understands that his decision is correct and is planning a plan to go south.

It's just a pity that he can no longer continue to lead troops now, and can only let other Taiji first set foot on the land of Great Yu.

But despite this, he never let go of his hatred for Xiao Ming. He has been waiting for a day when he can get revenge, but now he sees hope and has a wonderful plan in his heart.

...

Dengzhou.

Xiao Ming really enjoyed the pure and natural Haizhen of this era, and licked his lips unexplainably, and he smiled with satisfaction. 【】

This time he let the fishermen go fishing for abalone is not purely for his own enjoyment. His real purpose is to find a trading point for Dengzhou. There is no doubt that these sea treasures will become another income after table salt.

Nowadays, fiefs need development and money is needed everywhere. Qingzhou's industry, Youzhou's agriculture and animal husbandry, while Dengzhou relies on the sea to eat the sea. At present, he values ​​these three places most.

After tasting abalone, Xiao Ming tasted other seafood in Dengzhou in the next few days.

During the period, he did not idle, but inspected the situation of coastal defense. After he left Dengzhou last time, the soldiers from the construction camp arrived in Dengzhou. They built hundreds of forts along the military port, and these forts were all equipped with heavy artillery. Used to defend against attacks from the sea.

In addition to the military port, Yang Chengye also selected some coastlines where troops could easily land to build coastal defense forts. Now Dengzhou's strategic position is very important and he has to focus on defense.

In addition to the fort, Xiao Ming also inspected the conditions of the saltworks. With the help of the construction camp, some salt fields with concrete floors have been established in the current saltworks. When Xiao Ming arrived at the saltworks, hundreds of salt fields were drying salt. Not marginal.

The salt workers in the saltworks came and went, some of the salt in the salt pans were piled into salt mountains, white flowers and flowers. Seeing these salt mountains, Xiao Ming laughed happily.

"Your Majesty, since the use of this sea water for drying salt, the salt production of our salt farm has increased by more than a hundredfold. Now, not to mention the salt in the fief, it is not a problem to export it now, and after our sea salt is filtered and purified, the salt The quality is more than a little bit higher than that of domestic table salt. It can be said that our table salt has completely reached the level of tribute salt." Yao Wenyuan said excitedly.

Yang Chengye said with a smile: "His Royal Highness, Yao Wenyuan's words are not bad. When we were representing the country, our table salt from Dengzhou was sent to the palace as tribute salt."

Nodded with satisfaction, Xiao Ming was even relieved. He said, "If this is the case, the king will ask the Chamber of Commerce to come to Dengzhou to sell the salt."

Yang Chengye and Yao Wenyuan are overjoyed. They are all looking forward to increasing Dengzhou's finances through this salt.

After half a month of patrolling and playing in Dengzhou, Xiao Ming and Fei Yue'er set off for Qingzhou the next day. After all, he took care of everything that should be handled in Dengzhou. This time he asked the Chamber of Commerce to transport salt. .

He has great ambitions, and wants Dengzhou's salt to occupy the market in Dayu.

After three days of traveling, Xiao Ming and Fei Yue'er arrived in Qingzhou. They had just entered Qingzhou City, and Lin Wentao, who had heard the news, rushed over.

Xiao Ming asked Fei Yueer to go back first and asked, "What's wrong with Lin Wentao, is there something wrong with your steam engine?"

Lin Wentao grinned and said: "His Royal Highness, the steam engine is not a problem, but in just one month I converted the steam engine from the basic Newcomen steam engine to a compound steam engine."

"Double steam engine?" Xiao Ming said in surprise, but since Lin Wentao developed the Newcomen steam engine, he vaguely felt that the double steam engine was not far away, but he didn't expect this transformation to come so soon.

But this is also understandable ~www.wuxiaspot.com~ After all, the development of the Newcomen steam engine means that the problems of the cylinder, cylinder plug, and connecting rod have been solved, and the compound steam engine is just a small process on the Newcomen steam engine. Small makeover.

Generally speaking, to make the steam engine rotate efficiently, it is necessary to make the piston continue to reciprocate. First, let the hot steam enter the cylinder, which can push the piston upward.

Immediately after the piston is moved downwards, the steam entering the cylinder needs to be quickly condensed to reduce the volume and pressure.

Before Watt improved the steam engine, the Newcomen steam engine used to inject cold water into the cylinder, but this would lower the temperature of the cylinder itself, causing the next hot steam entering the cylinder to lose heat, which was very inefficient.

So Watt discovered this shortcoming when repairing this kind of steam engine, so he thought that since let the water vapor cool down and don't want the cylinder to cool down, let the water vapor come out of the cylinder and then cool again.

After all, these are all connected, and the air pressure in the cylinder can also be reduced.
