There are no vacant shops along the street, and they are full of novelties from all over the place. In the past few years, with the gradual calming down of the Western Regions. The ancient Silk Road has shown signs of gradual recovery, with caravans from the Western Regions entering and leaving Chang'an City in an endless stream every day. The people's money bags are full, and they are willing to spend in these shops that they would not dare to enter in the past. One after another, a good business environment has been formed. There may be many standards for the prosperity of a country, and many standards may contradict each other. But there is only one point that no one can deny. That is, if the country can make the lives of ordinary people have hope! Father and son Su Li and Su Che walked and watched all the way. Although he held his father's big hand, Xiao Sudi couldn't rest for a moment.
When he saw uneaten snacks, he would stop and raise his head to look at Su Li eagerly. In this regard, Su Li is different from other parents. Other parents prevent their children from eating outside food, mainly because they are afraid that it will be unclean and that eating will damage their health. But Su Che's body is like a little tiger, it is impossible for him to spoil his stomach. His 730 has a good digestion ability, and his appetite is several times that of ordinary children of the same age. Although the food in the Princess Mansion can be regarded as the best in the Tang Dynasty, but after getting used to delicacies from mountains and seas, it is natural for them to have an idea about simple and light food. This is human nature. Just walking around the Vermilion Bird Grand Dao, a full two hours have passed. This afternoon, the father and son tasted almost every food stall on the street. Su Che has a lively personality, and when he encounters interesting things, he will stop and watch them. Before you know it, it's dusk. The shops on the street and the hawkers who set up their stalls have all closed their stalls. Su Li took her contented son and walked slowly towards the princess mansion. Pedestrians are in a hurry everywhere, making the two seem more leisurely. "Father, I just found out that the waterwheel works like that." Su Che held Su Li's big hand and said excitedly. What he was talking about was the navy that the two of them saw just now in a shop that provided wooden gates for wealthy families. That thing is actually a scaled-down waterwheel model. Datang, as the land of Zhu Xia, is famous for its romantic dynasty, it is not a casual talk. One of the notable features is that various trends are updated very quickly. Recently Chang'an City doesn't know why, but there has been a trend of playing with gardens.
In this regard, rich and noble families have their own unique tricks, competing for excellence. Your family has a zoo-themed garden, and my family has a garden with a pure natural style. What's even more bizarre is that some people still prefer gardens with the theme of pastoral landscapes. For example, the waterwheel sold in the woodware shop just now is only one person tall, and has no practical function at all. But put it in the yard, make some rockery and flowing water, and reclaim several fields next to it. That feeling comes out just by scratching it! Some arty dignitaries like the smell of returning to the natural state. Su Li thought for a while and asked with a smile: "Then can you see where the power of the waterwheel comes from?" "Water flow! As long as there is a flow of water, the water wheel can keep turning to draw water." Su Che said happily. "Then Che'er, have you ever thought that we can artificially create a kind of power to drive various instruments to move on their own?" Su Li followed the temptation. Su Che's various attributes are frighteningly high, no matter what aspect he is, he is a real genius. Su Li doesn't believe in stick education when it comes to his son's education, but likes to teach through entertainment. Su Che is very curious. Today's outing, he is most concerned about the waterwheel. Su Li simply followed his words and asked him to think about this question. After raising this question, Su Li also felt a little emotional. He is familiar with the history of later generations, and has a high-level insight in many things. In this era, he knows better than anyone else the importance of productivity to a country. The power problem is the core problem that restricts productivity. (aebd) Before the invention of the steam engine, human productivity remained stagnant for a long time. The motivation people use most often is the human calendar and calendar. The use of natural power is also at a very Yuanshi level. Today's visit to Chang'an, Su Li also had a deeper understanding of the current situation in the Tang Dynasty. From his point of view, Datang's materials seem to be much richer than before, but this is far from enough! If you want to jump out of the mold and go further, the upgrading of productivity is imminent. Su Li's system warehouse Curry has complete steam engine manufacturing technology. However, he had no intention of taking it out. Su Li's mentality is becoming more and more lazy now, and he often feels that everything in the world is like a game to him. No matter who it is, with a life much longer than ordinary people, and after their strength breaks through the upper limit of human beings, they will inevitably feel this way.
At this time, his positioning of himself is more like a bystander outside the world. But today coincided with the meeting, Su Che suddenly became interested in the power issue. If it is to teach the son, then naturally there are no taboos. Su Li came up with a bold idea....... He wants to let little Su Che hand rub the steam machine! Hearing Su Li's question, Su Che immediately fell into deep thought. Thanks to Su Li's way of educating him, although Su Che is young, his way of thinking about problems is actually very mature. He was unusually quiet. Su Li didn't bother him either, just took his little hand, and the father and son walked towards home again at a slow pace. Back at the princess mansion, just in time for dinner. Su Li didn't take Su Che to wait for dinner, but led him all the way to the kitchen. He really wanted to guide Su Che, but he didn't intend to let his son really spend too much time on this matter. Su Li is well aware that ingenuity is of course important for the advancement of science. But more importantly, it was the flash of inspiration. This is true for several key nodes of scientific progress in later generations. For example, an apple that fell from a tree. Another example... a teapot lid for boiling water! The father and son walked into the kitchen, and Su Li pulled Su Che to a copper kettle that was boiling water. It is not uncommon for this kind of thin-mouthed copper pot to be popular in Chang'an now. Su Che stood in front of the stove, which was higher than himself, followed his father's instructions, and stared at the copper pot without blinking his eyes. "The thing you're looking for may be here." Su Li smiled and patted Su Che's head. After a while, the water in the copper pot boiled. The whistle placed on the lid of the pot made a sharp cry. At the same time, the boiling water makes the lid of the kettle jump constantly. Seeing this scene, little Su Che's eyes became brighter and brighter. He waved his little hand to stop the servants who ran over to remind him. The boiling water in the pot kept tumbling, and finally... With a click, the pot lid jumped up high and fell to the table. "Dad, I understand!".
