Xinguo Gongfu.
Han Du sat drinking with Tang He and Tang Ding.
Tang Hezheng, as he said, was too old. Originally, Han Du refused to allow him to drink. But Tang He said: "When I was young, I could drink whatever I wanted. Later, when I got old, countless people told me that my body and bones were getting worse day by day and that I should take care of myself. But I have been taking care of myself for so many years. , until now the dirt has been buried under my lips, and I have realized that I have made losses in the past few years. Since everyone is going to die, it is better to enjoy it before dying. "
Tang He is too old, his hair is completely white, not to mention the wrinkles on his face, the key is that his skin is densely covered with age spots. It was as if he had aged more than ten years in the past two years.
Han Du tried to persuade him several times but could not persuade him. Even Tang Ding was helpless and had to let him go.
However, in front of Tang He, Han Du tried to drink as little as possible and took care of Tang He's health.
After picking up a piece of food with chopsticks and eating it, he raised his head and glanced at the broom star still hanging in the sky, and said with a slight smile: "In this turmoil, more than a dozen ministers were killed. What do you think, sir?"
Tang He snorted and said casually: "What do you think? A group of people who don't know whether to live or die. Death is not a pity."
"Oh?" Judging from Tang He's meaning, it seemed that he knew something inside. Han Du couldn't help but become curious and asked, "Master, is there any secret in this?"
Tang He squinted his eyes and smiled, shook his head and said energetically: "It's not a secret, but not many people know about it. After the emperor founded the country, some civil servants used their high status to make excuses."
Han Du frowned when he heard this. This behavior of making excuses for people's origins, let alone the emperor, even ordinary people, would offend the other person to death, right?
These people say that Lao Zhu's background is not good. Isn't this just pointing at Lao Zhu's nose and calling him a nouveau riche?
"How can this emperor endure it? Why don't you chop all those people up?" Han Du said with a smile.
Tang He shook his head with a smile and said: "No, the superiors not only did not kill them, but seriously considered their ideas, and even planned to trace their roots."
"The emperor actually chooses to trace his roots and inquire about his ancestors? Who is so proud?" Han Du immediately lowered his voice, approached Tang He and asked curiously.
Tang He smiled and said two words, "Zhu Xi."
"Then why did the emperor regret it later?" Han Du didn't need Tang He to tell him, he knew that this matter would definitely not be done in the end. Otherwise, Zhu Xi's shrine should be worshiped in the Ancestral Temple. I didn’t see it when heaven and earth were offering sacrifices together.
Tang He said calmly: "Later, it was the Empress who came forward to persuade me to give up the idea of ascending to the throne."
After a pause, Tang He slowly sighed and said: "Originally when the emperor was preparing to recognize Zhu Xi, those people were celebrating and rejoicing, but later when they saw that the emperor never mentioned it again, they hated it even more. The superiors also knew what they were thinking, but the superiors didn't care, so the matter was settled. I didn't expect that after so many years, these people still haven't given up and caused such things."
"Then what happened to the Duke of Han?" Seeing Tang He talking with great interest, Han Du took the opportunity to ask more questions.
Tang He chuckled and whispered harmoniously: "Although the superior was very angry with these people back then, he also knew that these people would not be able to function in the court without them, so he did not pursue them and turned this matter into a trivial matter. It melted and finally came to an end.
But later, the superior asked Li Shanchang to preside over the formulation of court etiquette, as well as the style of official uniforms and salaries of various officials. "
Understood, Han Du suddenly looked at Tang He with a look of understanding in his eyes. These people must have thought that Li Shanchang had robbed them of their opportunity, and they had held grudges ever since. In the past, they could not find the opportunity to add insult to injury, but now that Li Shanchang was imprisoned by the emperor, they thought that an opportunity would come, so they couldn't wait to jump out.
"What about the Duke of Han? In my opinion, why did the emperor put him in prison?" Han Du thought of the triggers of these things and asked curiously.
Tang He smiled and asked in astonishment: "Why do you care so much about Li Shanchang? Is there something between you and him?"
While talking, Tang He's eyes never left Han Du's face, staring at him closely.
Han Du shook his head and replied calmly: "He and I didn't even talk about going together. I just asked out of curiosity."
Tang He laughed and continued to talk to Han Du calmly: "Li Shanchang is a man with a strong desire for power. If it were me, when the superior asked him to retire and return to his hometown for the first time, he would have stipulated that Go back in a good manner and never set foot in the court again, but he just wants to come back shamelessly..."
When he said this, both Tang and He couldn't help but shook their heads and sighed: "What he did has long been disliked by the superiors. If the superiors hadn't seen that he had made great contributions in the southern and northern wars, maybe I have been rude to him for a long time. To be honest, I don’t dare to guess what will happen to him this time, and I can’t guess it.”
Han Du closed his lips tightly and nodded subconsciously without saying anything more.
The broom star hung in the sky for twenty-eight days, and finally one early morning, it left the world with its big-tailed figure and disappeared into the vast universe.
The Broom Star has disappeared, but the topic about the Broom Star, or rather the topic about Han Jingyun, has not disappeared.
This time the broom star celestial phenomenon is not only spectacular and shocking. What most people talk about is that every step of the process from the appearance to the disappearance of the Broom Star was carefully planned by Han Jingyun.
People even felt that the Broom Star was no longer a celestial phenomenon, but a chess piece in Han Jingyun's hand. It appeared whenever they wanted it to appear; it disappeared whenever they wanted it to disappear.
Several years later, Han Jingyun's reputation as a scheming figure in the world once again resounded throughout the world. This time, it was not because of her status as a princess, but because of her attainments in mathematics that she was admired by people all over the world.
After all, Han Jingyun is a divine being who can even calculate the celestial phenomena. How could the people not worship her?
This time, the academy also took advantage of Han Jingyun's influence, and its prestige in the eyes of the people was greatly improved. Countless young students know mathematics, know Han Jingyun, and know the academy. No one dares to say that mathematics is a minor path anymore. After all, one can even calculate celestial phenomena. If this is considered a minor path, is there any knowledge in the world that is a major path?
More students became interested in mathematics for the first time, and many even chose to study in academies, with the purpose of seeing the true face of this magical knowledge in Mount Lu.
But what these ambitious students who want to make great achievements in mathematics do not understand is this. Why, when they first entered the academy and said they wanted to study mathematics, the students in the academy all looked at them with concern.
A few days after the broom star disappeared, Lao Zhu finally made a verdict against Li Shanchang.
"Li Shanchang was suspected of conspiring with Hu Weiyong to rebel. However, due to insufficient evidence, Li Shanchang was sentenced to death, retained his title and moved his family to Java. Marquis of Ji'an Lu Zhongheng, Marquis of Yan'an Tang Shengzong, Pingliang Marquis Fei Ju, Nanxiong Marquis Zhao Yong, Xingyang Marquis Zheng Yuchun, Yichun Hou Huangbin, Hou Luju of Henan and others were executed together. They also retained their titles and moved their families to Nanyang."
Han Du could tell from Lao Zhu's treatment of Li Shanchang that Lao Zhu really hated him, otherwise he would not have had to move his family to Java. If we move to Nanyang, there is still room for maneuver.
After all, Luzon also belongs to Nanyang, but it is not far away from the Ming Dynasty at all. Moreover, Luzon is prosperous and can be regarded as a peaceful place.
But Java is different. Although Java also has a governor's palace, almost no Ming people settled there. Java is full of natives, and after Li Shanchang's family has gone, I am afraid they will be the only Ming people in Java.
Han Du was not surprised by Li Shanchang's death. After all, he had known that Tang He had said that Lao Zhu would not let Li Shanchang go easily. However, Han Du didn't have much deep feelings about this. After all, he and Li Shanchang were not familiar with each other in the first place, and they had no contact with each other.
Han Du followed Tang He to express his condolences after Li Shanchang was sentenced to death.
Suddenly, more than ten wealthy families in the capital were all in silence, pouring a basin of ice water on the newly bustling capital. At this time, all the officials remembered that the person sitting on the dragon throne was not only a dying old man, but also a ruthless man who had "killed millions of soldiers in the south of the Yangtze River, and the sword on his waist was especially bloody."
Han Du felt very depressed because of this, and didn't want to go to court, so he simply used the excuse that the safe princess had an itchy body and stayed at home.
This is one of the benefits of being a consort.
However, Han Du did not remain free for long before the old man Tao Chengdao came to his door.
After hearing the news, Han Du rushed from the courtyard to the lobby. As soon as he walked in, he said with a smile: "I'm sorry for being late to welcome you. Wanhu can come here, it's really a blessing."
When Tao Chengdao heard Han Du's voice, he immediately raised his head. He didn't even care about drinking the tea he had yet to drink, and put it on the table. He quickly stepped forward and took Han Du's arm, and walked out without even thinking about it. "Let's go and help me find out. What's the problem?"
Han Du was inexplicably surprised. After suddenly coming to his senses, he quickly grabbed Tao Chengdao and said, "Wanhu, let's not be in such a hurry. Even if there is any problem, why don't we waste time for a cup of tea?"
If Tao Chengdao comes to the house and Han Du doesn't even drink a cup of tea with him, if word gets out, people may say that Zhenhai Houfu doesn't understand etiquette.
Han Du was not used to these red tapes when he first came here, but after all, he was living in such an environment, and it would be impossible not to follow the local customs.
When Tao Chengdao heard this, he immediately raised his beard and scolded loudly: "Drink the damn tea. I never care about the kind of tea. I only drink it when your servants serve it to me. I am usually busy." When I get up, I can fill several bowls of cold water."
"Come on, don't talk to me!"
Han Du had no choice but to let Tao Chengdao pull him away.
Once again, we came to Tao Chengdao's house. As soon as we walked into the backyard, we saw a huge thing placed on the ground, with cut corners everywhere.
Han Du walked up to the thing with a surprised expression, turned around and asked Tao Chengdao: "Wanhu, did you really make the thing?"
Upon hearing this, Tao Chengdao looked at Han Du carefully, and when Han Du was looking at him with confusion, he said: "Originally, I thought you were an honest boy, but I didn't expect that you are also a cunning person."
"Here, where do you start talking about Wanhu?" Han Du was scolded in person without hesitation, but he didn't dare to get angry, so he could only touch his nose and ask with a smile.
Tao Chengdao glanced at Han Du with disdain and blurted out: "When you didn't know my identity, you called me old man; after you knew my identity, you changed your name to old man. I said you are cunning and cunning. Is it wrong?"
Han Du was so embarrassed that he almost dug out three rooms and one living room with his feet on the ground. After coughing twice, he changed the subject and said: "Wanhu came to me in such a hurry. What is the important matter?" Han Du was reminding him. This old man, be careful what you say. It's enough to accuse Sang and Huai to push him once. If he keeps pestering him, have he forgotten that he has something to ask of him?
Although Tao Chengdao, an old man, spoke straightforwardly, he was actually very thoughtful, and he immediately understood the meaning in Han Du's words. He didn't dwell on it, and instead said: "I have made such a big Kongming Lantern, but now the oil lamp has become a problem."
"What's the problem?" Han Du asked.
Tao Chengdao sighed heavily and said helplessly: "I made the oil lamp big enough, but the heat generated can't hold it up."
Before the Kongming Lantern takes off, it needs to rely on the oil lamp to fill the interior with hot air and prop up the paper before it can fly into the sky. Now that I can't even hold myself up, I can't even talk about flying into the sky.
"Where is the oil lamp? Take me to see it." Han Du entered a rational state as soon as he encountered a problem. He stopped arguing with Tao Chengdao and said directly.
Tao Chengdao brought Han Du to the oil lamp.
Han Du took a look and felt that the oil lamp was really big enough. The wick in the middle alone is as thick as an adult's fist. One part of the wick was burnt black, and the other part was white. It had obviously been set on fire. There is a huge oil can connected below, which is filled with oil as fuel.
As soon as Han Du came here, he sniffed, then stretched out his finger to light the wick, put it under his nose and smelled it. Rubbing the grease on his fingers casually, he turned around and asked Tao Cheng, "Wanhu, are you using clear oil?"
Tao Chengdao responded matter-of-factly: "Isn't the oil lamp just the clear oil for lighting?"
Han Du immediately shook his head and said, "Clear oil won't work." Clear oil is a kind of vegetable oil. Although ordinary oil lamps can be used, it is obviously impossible to fly this hot air balloon into the sky. Because clear oil is not easy to burn, and the caloric value it provides is not enough.
"Then what should I use?" Tao Chengdao asked subconsciously, and then said in surprise: "You don't want to use strong fire oil, do you?"
Han Du immediately smiled and nodded, and said: "It's fierce fire oil. But ordinary fierce fire oil alone is not enough. It needs to be refined before it can be used."
"I have fierce fire oil here, but how to refine it?" Tao Chengdao suddenly felt a little embarrassed after hearing Han Du's request.
Han Du pondered for a moment and said, "It's a bit dangerous to refine this thing."
Hearing this, Tao Chengdao quickly asked: "Danger? How dangerous?"
Han Du gestured with his hands and said to him: "Let's put it this way, fierce fire oil is easy to burn when it catches fire, and it may explode. But if we want to extract something suitable for use, we must burn the fierce fire oil. Heating and then distilling and separating can get what we want."
"Think about it, if you think about it, fire oil is most afraid of flames, and we have to take the initiative to put it on the fire. Is this dangerous?"
After hearing this, Tao Chengdao said nonchalantly: "What are you doing without danger? I first became interested in firearms because the alchemy furnace exploded when I was refining elixirs. Just like making gunpowder, there are risks. But every time I I have been vigilant and careful every time I acted, and nothing has happened so far, right?"
After hearing Tao Chengdao's words, Han Du suddenly felt that he was lighting a lamp to a blind man in vain. After all, Tao Chengdao is a ruthless man who even dares to ride on a rocket speed car. To him, any danger is not worth mentioning.
Perhaps in his belief, he has never been afraid of anything because of exploration, not even death. Of course, his spirit deserves to be greatly promoted, but his behavior must be resolutely eliminated.
Han Du could only nod and said: "Well, Wanhu's words make sense. Now I will tell Wanhu the method of refining fierce fire oil, and Wanhu will have people prepare relevant things. Then, we must pay attention to some safety and try it first. Once successful, we will officially start production."
Handu does not know how to industrialize oil refining. What Handu knows is only local oil refining. This method not only consumes a lot of money, but also produces toxic and harmful gases during the process. Of course, this gas will not poison people immediately, otherwise people like those in Africa who secretly refine oil would have been poisoned long ago. Of course, if you are exposed to this gas for many years, it will definitely be very harmful to people.
Han Du's method is very simple. A big pit, a big stove, and a big iron can filled with hot oil are the equipment for local oil refining. After the fire oil is heated, the steam formed will cool down in the pipe, and "gasoline" and "diesel" flow out from the "high pipe" and "low pipe" respectively. Due to the different boiling points of gasoline and diesel, gasoline will be evaporated first during distillation, while diesel has a much higher temperature and can only be evaporated later.
The danger Han Du said is that during the heating process, once the fire burns too brightly and the temperature in the iron can is too high, spontaneous combustion will occur, the crude oil will ignite, and an explosion will occur.
