The wound on the middle finger was still aching. Pen fun and pavilion www.biquge.info

Bei Shan still remembers the humiliation suffered in the Battle of Jizhou, the last fiasco caused the Blood Wolf Tribe to lose more than half, and the guilt of losing Shanhaiguan made his father Khan furious.

If it weren't for his mother's intercession with the leader of the Tula tribe, he would have had to atone for his sins with his life instead of cutting off the three fingers of his left hand.

After that, he was ordered to surrender his military power, and now he can only live in Goryeo, nominally supervising the vassal state.

"That's it, it's not his fault, this King of Qi of the Great Yu Kingdom is not so easy to deal with." Pei Shan forcibly suppressed his anger, his eyes rolled, and with his sensitive sense of war, he felt that a war seemed to be getting closer.

When the king of Goryeo heard this, he shouted to Park Jung-ho: "Beshandaeji has been merciful and forgives you, and he will not be thankful and retreat." ”

Vice General Kim suddenly kowtowed, and Park Jung-ho also knelt on the ground.

Turning his head to look at Bei Shan's thoughtful look, the King of Goryeo breathed a sigh of relief in his heart, he really didn't want to punish his generals for this matter, after all, they were also his own generals no matter what.

At this time, Pei Shan looked at the sea in the south and said to the king of Goryeo: "How long does it take to get from here to Dengju?" “

"Back to Taiji, it's very close to Dengzhou, and it takes a day to get to Dengzhou by boat." The King of Goryeo said cautiously.

"One day?" There was a strange glint in Pei Shan's eyes, and he then asked, "How many soldiers can your sailors transport at one time?" ”

"10,000 people is still okay." The king of Goryeo suddenly had a very bad premonition.

Nodding slightly, Bei Shan said: "It's too little, from now on, you Goryeo will use all means to step up shipbuilding and prepare for the Golden Horde to send troops to the Great Chongqing State." ”

The king of Goryeo's heart trembled, and he asked nervously, "Is the Heavenly Khan ready to go south?" “

"It's getting colder and colder in the north, and our cattle and sheep freeze to death a lot every year, and they become bullshit when they recuperate, and if we don't go south, our people will starve to death." Bei Shan sneered.

Although his rash advance led to the defeat at Jizhou and the loss of Shanhaiguan, he had been pushing the Golden Horde southward, and now the banner leaders of the tribes on the steppe finally understood that his decision was correct and was planning to go south.

It's just a pity that he can't continue to lead the troops now, so he can only let the other Taiji set foot on the land of Dayu first.

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

……

Dengzhou.

Xiao Ming really enjoyed the pure natural sea treasure of this era once, and licked his lips unsatisfied, and he showed a satisfied smile.

This time, he let the fishermen go out to sea to catch abalone for his own enjoyment, his real purpose was to find a trading point for Dengzhou, and there is no doubt that these sea delicacies will become another income after salt.

Now the fiefdom needs to develop, money is needed everywhere, Qingzhou's industry, Youzhou's agriculture and animal husbandry, and Dengzhou relies on the sea to eat the sea, and what he values most at present is these three places.

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

After his last departure, the soldiers of the construction battalion arrived in Dengzhou, and they built hundreds of batteries along the military port, which were equipped with heavy artillery to defend against attacks from the sea.

In addition to the military port, Yang Chengye also selected some coastlines that were easy for large armies to land on to build shore defense batteries.

In addition to the fort, Xiao Ming inspected the situation of the salt field, and now the salt field has established some cement ground salt pans with the help of the construction battalion, when Xiao Ming arrived at the salt field, hundreds of salt fields were drying salt, and there was no edge in sight.

The salt workers in the salt field came and went, and the salt in some of the salt fields was piled up into salt mountains, a piece of white flowers, seeing these salt mountains, Xiao Ming smiled happily.

"Your Royal Highness, since the use of this seawater salt, the salt production of our salt farm has increased more than a hundred times, not to mention the salt in the fiefdom, it is not a problem to export now, and our sea salt has been filtered and purified, the quality of this salt is more than a little higher than the quality of domestic salt, it can be said that our salt has completely reached the level of tribute salt." Yao Wenyuan said excitedly.

Yang Chengye said with a smile: "Your Highness, Yao Wenyuan's words are not bad at all, when we were in the country, the salt of our Dengzhou was sent to the palace as tribute salt." “

Nodding with satisfaction, Xiao Ming was even relieved in his heart, and he said: "Since this is the case, this king will go back and let the Chamber of Commerce come to Dengzhou to bring the salt back to sell." “

Yang Chengye and Yao Wenyuan were overjoyed, and they were both looking forward to increasing Dengzhou's finances through this salt.

After half a month of inspection and play in Dengzhou, Xiao Ming and Fei Yue'er set off to return to Qingzhou the next day, after all, he dealt with everything that should be dealt with in Dengzhou, and this time he asked the Chamber of Commerce to transport salt.

His ambition was great, and he wanted Dengzhou's salt to occupy the market of Dayu.

After three days, Xiao Ming and Fei Yue'er arrived in Qingzhou, and as soon as the two entered Qingzhou City, Lin Wentao, who learned the information, rushed over.

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

Lin Wentao said with a smile: "Your Highness, there is no problem with the steam engine, but in just one month, I changed the steam engine from the basic Newcomen steam engine to a duplex steam engine. ”

"Duplex steam engine?" Xiao Ming was surprised, but since Lin Wentao developed the Newcomen steam engine, he vaguely felt that the duplex steam engine was not far away, but he didn't expect this transformation to come so quickly.

However, this is also understandable, after all, the development of the Newcomen steam engine means that the problems of cylinders, cylinder plugs, and connecting rods have been solved, and the duplex steam engine is just a small modification to the Newcomen steam engine.

Generally speaking, in order to make the steam engine rotate efficiently, it is necessary to let the piston continue to reciprocate, one is to let the hot steam enter the cylinder first, so that the piston can be pushed upward.

The piston is then moved downward, which requires the vapor entering the cylinder to condense quickly to reduce the volume and pressure.

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

So Watt discovered this drawback when he was repairing this steam engine, so he thought that since he let the water vapor cool down and didn't want the cylinder to cool down, it would be enough to let the water vapor come out of the cylinder and then cool down.

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