Many things in the world do not make sense at all. Most people have boiled water all their lives, never thinking that the steam from boiling water is actually a kind of power. In fact, human history has been thousands of years, and it is unknown how many generations have passed. In the end, there was only one person who discovered this principle. Of course, the appearance of the steam engine in later generations is not due to one person. But with the development of the times, Yuanshi's power can no longer meet the needs of human beings, which eventually led to the birth of the steam engine. There is one thing to say, today's Datang is far from the point where it needs mechanical power. Datang's products have not yet developed to the limit at this stage, and there is no soil for the birth of steam engines. However, for Su Che, these are not problems. He didn't live in those times.
But, who let him have an omnipotent father? With Su Che's intelligence and Su Li's proper guidance, it is almost natural to rub the steam engine by hand. For the next few days, the father and son stayed at home, spending every day in the study, studying how to make a steam engine. "For a complete power system, energy, power compression and transmission, these three conditions are all necessary!" Su Li said, looking at Su Che seriously. The table next to the two of them was already filled with papers full of patterns. The above paintings are the appearance of the steam engine imagined by Xiao Su. There are gossip patterns, egg shapes, and the most bizarre thing is that there is something that looks like a horse. He also plausibly explained that the horse-shaped steam engine was Bailong's inspiration for him. Horses are originally animal power, and as the top grade of horses, Bailong can travel thousands of miles and carry tens of thousands of catties. Since the horse can reach that limit, there must be some reason. Therefore, it must be easy for the steam engine to form a horse shape. This kind of theory is similar to what to eat to make up for the difference, which made Su Li dumbfounded. His son's mind was wide open, and Su Li did not discourage his enthusiasm. Whenever Su Che drew an outline drawing of a steam engine, he would seriously discuss it with him. Is it okay to do this, and if not, where is it not. After several days of tossing, little Su Che finally realized that all the shapes he designed were meaningless before he figured out the internal structure of the steam engine. He finally calmed down and asked Su Li honestly for advice. Su Li was succinct and told Su Che directly about the core structure of the steam engine. After hearing Su Li's words, little Su Che fell into deep thought.
Then, he began to study these three issues with great concentration. The first energy issue, it's not going well. These days, common people basically use firewood for heating, while rich people use charcoal. However, whether it is dry wood or charcoal, the combustion efficiency is actually not good. Even if it is charcoal, the energy density is very low, and it must not be burned if it is used as the energy source of the steam engine. And the problem of compression is also very difficult. Steam is used as power, and if you want to compress it, the first thing you need to ensure is airtightness. Little Su Che tried a lot of materials, but finally found that none of them were feasible. Good seal, not soft enough. And the material is soft enough, but there is no sealing at all. The transmission problem is easy to say, as long as you are willing to try it, you can solve it sooner or later. Seeing her son being troubled by her own problems for several days, Su Li felt that it was almost done, and found Su Che again. He first took out a piece of coal and asked Su Che to experiment. Then Su Che discovered excitedly that this kind of black stone fully meets the requirements of the steam engine. Coal is actually not uncommon in the Land of Zhu Xia. As early as in Yuanshi society, the people of Zhuxia began to use coal for heating. In the pre-Qin period, this thing was called burning stone. The burning fire is strong and long-lasting, but it is limited to mining conditions, and it has not been used on a large scale so far. In addition, Su Li took out the rubber material purchased from the system and handed it over to Su Che. There is no doubt that the airtightness problem is also solved. In less than a month, little Su Che really built a steam engine with only one hand. After the finished product came out, Su Che pestered Su Li every day, asking him to find coal and rubber for himself. Coal is easy to say, there are a lot of it in Bingzhou, the land of Longxing where Li Er and his father and son lived. Not to mention those buried underground, there are quite a few open-pit coal mines, but no one mines them. But rubber is a bit tricky. The origin of this thing is on the other side of the ocean. But when the son was three years old, it was rare for him to do a serious thing. As a father, this matter is difficult but has to be done!
So Su Li called up another fleet to search for rubber. 0…ask for flowers…… Time passed day by day, and before he knew it, it was the eldest grandson Wugou's birthday. As an empress, the eldest grandson Wugou's frugality is very famous in history. This birthday, because it is not a big birthday every tenth, so the couple did not make a big fuss. It was just a family banquet held in the palace, and all the relatives of the Li family in Chang'an were invited over to have a meal together. Of course, Su Li couldn't refuse this kind of thing. Recently, Li Er frequently showed his affection, and even specially asked Su Li to chat alone for a while at the birthday banquet. Seeing that Su Li's attitude was the same as before, Li Er's heart was finally relieved. Full of wine and food, Fude official. Su Che and other juniors were left in the palace to accompany the queen. In the dead of night. When Li Er came to Changsun Wugou's bedroom, he saw Changsun Wugou walking out with a roll of paper in his hand. Seeing that Li Er was about to speak, Changsun Wugou quickly gestured to him, signaling Li Er not to speak. When the two came to the courtyard of the bedroom, the eldest grandson Wugou let out a sigh of relief. "What are you doing?" Li Er asked a little funny. "This kid, Che'er, has too much energy. After playing around all day, he didn't feel tired at all. It took me a long time to coax him to fall asleep." Changsun Wugou said with a smile on his face. In the past few years, the number of times Chang Le entered the palace was very small, the grandmother, Changsun Wugou, never saw her own grandson a few times throughout the year. However, she really likes this grandson from the bottom of her heart. It was rare for Su Che to stay overnight in the palace today, the eldest grandson Wugou purposely kept him in his bedroom, but he caused trouble for himself. After listening, Li Er couldn't help laughing. Afterwards, he pointed to the roll of paper in Changsun Wugou's hand, and asked, "What is this?" "This one? Che'er brought it into the palace. According to him, it was some kind of world map drawn by Su Li. Li Er couldn't help being taken aback, and curiously took the map from his eldest grandson. Spreading it out, Li Er was stunned. The details of this map are completely beyond his imagination. What shocked him even more was that Datang only occupied a palm-sized area on this map. What?
I took all the surrounding areas of Datang into my bag, but what Datang actually occupies is only the tip of the iceberg in this world? Li Er was stunned, and then suddenly there was an impulsive feeling in his heart that hadn't appeared for a long time.
