The wound on his middle finger still throbbed faintly.
Bei Shan vividly remembered the humiliation suffered in the battle of Jizhou. The last disastrous defeat caused the Blood Wolf tribe to lose more than half its forces, and losing Shanhaiguan enraged his father, the Khan, like thunder.
If it weren’t for his mother and the leader of the Tula tribe pleading for mercy, he would have had to pay with his life rather than just lose three fingers on his left hand.
Afterwards, he was ordered to hand over command of the army and now had to live in Goryeo, officially supervising this vassal state.
“Forget it. It’s not his fault. The Great Yu’s Prince Qi is not so easy to deal with,” Bei Shan forcibly suppressed his anger. His eyes shifted. With his sharp sense of war, he felt that a new conflict was drawing closer.
The Goryeo king said to Park Jeong-ho, “Bei Shan Taiji is kind-hearted and has spared you. You should thank him and withdraw.”
Vice General Kim kowtowed repeatedly, and Park Jeong-ho bowed down on his knees.
Turning his head to look thoughtfully at Bei Shan, the Goryeo king sighed in relief. He really did not want to punish his generals over this. After all, they were still his men.
Bei Shan then looked toward the southern sea and asked the Goryeo king, “How long does it take to sail from here to Dengzhou?”
“Taiji, Dengzhou is very close. It takes only one day by boat to reach,” the Goryeo king answered cautiously.
“One day?” Bei Shan’s eyes gleamed strangely. Then he asked, “How many soldiers can your navy transport at once?”
“Ten thousand is still possible.” The Goryeo king suddenly had a very bad feeling.
Bei Shan nodded lightly and said, “Too few. From now on, Goryeo must use every method to speed up shipbuilding and prepare for the Golden Horde’s campaign against Great Yu.”
The Goryeo king shuddered in his heart and nervously asked, “Is the Great Khan preparing to march south?”
“The north grows colder every year. Many of our cattle and sheep freeze to death annually. Rest and recuperation is nonsense. If we don’t go south soon, our people will starve to death,” Bei Shan sneered.
Although his rashness caused the defeat in Jizhou and the loss of Shanhaiguan, he had continuously pushed for the Golden Horde to move south. Now the tribal leaders on the steppe finally realized the correctness of his plan and were preparing for the southern campaign.
Unfortunately, he could no longer lead the army himself and had to let other Taijis set foot on Great Yu’s soil first.
Even so, he never let go of his hatred for Xiao Ming. He waited for the day to take revenge, and now he saw hope and had devised a brilliant plan.
…
Dengzhou.
Xiao Ming truly enjoyed the pure natural seafood of this era, licking his lips with satisfaction.
The fishermen were sent out to catch abalone not just for his own enjoyment. His real purpose was to find trade goods for Dengzhou. Without a doubt, these sea delicacies would become another source of income after salt.
His fief needed development and money everywhere: Qingzhou’s industry, Youzhou’s farming and herding, and Dengzhou relying on the sea. These were the three places he valued most.
After tasting the abalone, in the following days Xiao Ming sampled other kinds of seafood in Dengzhou.
He was not idle during this time, inspecting the coastal defenses. After he last left Dengzhou, soldiers from the construction camp had arrived and built hundreds of artillery batteries along the military harbor. These batteries would be equipped with heavy cannons to defend against attacks from the sea.
Besides the harbor, Yang Chengye had chosen some coastlines vulnerable to large-scale landings and built shore defense batteries. Dengzhou’s strategic position was very important and had to be heavily defended.
Xiao Ming also inspected the salt fields. With the help of the construction camp, cement-floored salt fields had been established. When he arrived, hundreds of salt pans were drying salt as far as the eye could see.
Salt workers moved busily around. Salt in some pans had piled into white mountains. Seeing these, Xiao Ming smiled happily.
“Your Highness, since using seawater salt evaporation, our salt production has increased by over a hundred times. Now, selling salt outside the fief is no problem. Moreover, after filtering and refining, our sea salt quality surpasses domestic salt. You could say our salt has reached tribute-level quality,” Yao Wenyuan said excitedly.
Yang Chengye smiled, “Your Highness, Yao Wenyuan’s words are true. In the past, our Dengzhou salt was even sent to the palace as tribute.”
Xiao Ming nodded with satisfaction and felt reassured. He said, “In that case, I will have the merchants come to Dengzhou to buy and sell the salt.”
Yang Chengye and Yao Wenyuan were overjoyed, hoping to increase Dengzhou’s revenue through salt sales.
Half a month passed quietly as Xiao Ming toured and inspected Dengzhou. The next day, Xiao Ming and Fei Yue’er set off back to Qingzhou. He had handled all matters in Dengzhou and planned to have the merchants transport salt from there.
His ambition was great: to have Dengzhou’s salt dominate the Great Yu market.
After traveling for three days, Xiao Ming and Fei Yue’er arrived in Qingzhou. As they entered the city, Lin Wentao hurried over upon hearing the news.
Xiao Ming told Fei Yue’er to return ahead and asked, “What is it, Lin Wentao? Is there a problem with the steam engine?”
Lin Wentao smiled, “Your Highness, the steam engine is fine. But in just one month, I have upgraded the Newcomen steam engine into a compound steam engine.”
“Compound steam engine?” Xiao Ming was surprised. Since Lin Wentao developed the Newcomen steam engine, he had sensed the compound steam engine was near, but he didn’t expect the upgrade to come so quickly.
This made sense. The Newcomen steam engine’s invention solved issues with the cylinder, piston, and connecting rod. The compound steam engine was just a small modification of the Newcomen.
Overall, to make the steam engine run efficiently, the piston had to move back and forth continuously. First, hot steam enters the cylinder, pushing the piston up.
Then the piston needs to move down. To do that, the steam in the cylinder must condense quickly to reduce volume and pressure.
Before Watt improved steam engines, the Newcomen engine injected cold water into the cylinder. But this cooled the cylinder, causing the next hot steam to lose heat and lowering efficiency.
Watt, when repairing such engines, noticed this flaw and thought: since we want the steam to cool but not the cylinder, let the steam exit the cylinder first, then cool it outside.
After all, the cylinder and condenser are connected, so the pressure in the cylinder can still drop.
