The scene was shocking. Everyone was possessed, looking at the fire on the ground in disbelief, and then at the ice cubes in Li Qinzai's hand.
So, what was the operation just now? Why can a perfectly good piece of ice create fire?
This scene broke everyone's cognition. In their original cognition, water and fire were incompatible. Why could ice cubes turn into fire in Mr. Li's hands?
The dandies were excited, and many people did not even want to believe that this was so-called knowledge. It was obviously an immortal method.
Qiao'er jumped up, climbed up Li Qinzai's thigh like a monkey, neatly took the ice cube in Li Qinzai's hand, and then turned it over to check.
"Dad, is this an immortal weapon?"
Li Qinzai said with a smile: "It's not an immortal weapon, it's just a piece of ice."
Qiao'er blinked: "Oh..."
After a while, Qiao'er said again: "So, can it make something delicious?"
"...It is not a magical weapon and cannot be turned into something edible."
Li Sujie looked at the ice cubes in Qiao'er's hand with a dull look on his face. The shocking scene just now still lingered in his mind for a long time.
"First...sir, wasn't that an immortal magic just now?" Li Sujie said with a smile.
Li Qinzai shook his head: "It's knowledge, not magic."
Li Sujie suddenly bowed his head and said, "Sir, please teach me."
All the dandies saluted and said in unison: "Please teach me, sir."
Li Qinzai rolled his eyes and said, "You haven't learned to walk yet, so you want to run away?"
"You don't know anything about the basics. You have just memorized Jiujiu Ge, and you think you are good at it?" Li Qinzai curled his lips and said, "What you just said, in terms of physics, you can also call it 'Gewu'. The guru is profound.
The knowledge of human beings, arithmetic is nothing but the foundation and tool of studying things.”
"Learn the numbers and formulas in arithmetic well and apply them to the study of objects. Only then will you have scratched the surface of the study of objects."
Li Sujie and the other dudes fell into deep thought and murmured: "Arithmetic...is just the basics?"
"That's right, it's just the basics. The grid is more complex and grand than mathematics. It involves many aspects. What I just demonstrated to you is the optical part of the grid. The convex ice cube condenses the light into the focus and converts it into heat energy, so it can produce fire.
"
"It's not magic, it's knowledge. Different from the collection of classics and history you read, my knowledge can explain the principles of various things in life and can also be applied to life."
"Why can't ordinary people lift a thousand kilograms of heavy objects? Why do fans make people feel cool in summer? Why do Tang soldiers' sword handles have striped and convex patterns? Why do the sows in the village scream in the middle of the night?"
Everyone who was listening intently was suddenly startled:???
Li Qinzai said without changing his expression: "The last one doesn't count. In short, the study of physics is very profound and complicated. It takes many years of study to even scratch the surface."
"You are not the eldest son in your family. You don't have to inherit the throne or title. You don't have to worry about money and livelihood. You have lived a useless life all your life. If you can learn a little bit of knowledge about objects, your life will not be wasted."
Li Sujie said thoughtfully: "My disciple once heard that the divine arm bow and horseshoe created by Mr. have been used by military officers, and the pulley set has also been used by the Ministry of Industry. Are these all based on the principles of geophysics?"
Li Qinzai said with a smile: "Yes, they can all be explained by the science of geology. The principles are to use the least labor-saving method to create the greatest efficiency. This is the original intention of applying the science of geology to life."
Li Sujie bowed his head and said: "Sir, I am a great talent, and my disciples admire you. I am willing to study with you sincerely in this life. If I can get a glimpse of the way of investigating things, I will die in peace."
The other dandies also bowed their heads in admiration and saluted.
Different from his attitude towards studying last time, Li Qinzai could see that everyone was really sincere in their salutes at this time, and they finally became interested in his knowledge.
Li Qinzai said calmly: "It doesn't matter whether you study or not. Tuition fees cannot be owed anyway. This is the bottom line."
On the way back, Qiao'er jumped up and down, but her little hand held Li Qinzai tightly and never let go for a moment.
"Dad was so awesome today. Those fellow apprentices admired him so much that they all knelt down and worshiped him." Qiao'er said happily.
Li Qinzai smiled and said: "It's not that I'm great, it's that my knowledge is great. Even if they want to worship me, it's their knowledge that they want to worship, not me."
"Learning belongs to my father, so he is also very powerful."
Qiao'er's eyes were shining with light that she had never seen before, and her eyes were full of pride.
Looking at his eyes, Li Qinzai was suddenly startled. He realized that children actually need someone to admire.
In a normal family, the object of children's admiration is usually the father. The father can always do anything easily, which makes the children feel sincere admiration, which leads to the mentality of imitating him.
The father and son Li Qinzai and Qiaoer are not considered a normal family, but Li Qinzai will always try his best to give Qiaoer what he needs, and at the same time assume the responsibility of a mother.
If there is any gain from making fire with ice cubes just now, the biggest gain is that Li Qinzai unintentionally gained Qiao'er's admiration and realized that the child is growing up every day and his psychological needs are different at each stage.
"Dad, if Qiao'er is also full of knowledge, will others admire me as much as they admire dad?" Qiao'er raised her head and asked.
Li Qinzai thought for a while and said: "The purpose of learning is not to gain the admiration of others, but to make life more convenient for yourself and others."
Looking at Qiao'er's confused eyes, Li Qinzai smiled again and said: "Of course, it is also to improve my self-cultivation and conversation."
"For example, when you see heavy snow falling from the sky, you can't help but say, 'I'm thinking about it now, it's raining and snowing', or 'Life is like that everywhere, it should be like a flying dragon stepping on snow and mud', instead of 'Damn, it's so white.
Snow', this is the difference between reading and not reading."
Qiao'er seemed to understand, but nodded repeatedly.
The father and son walked slowly and chatted while walking. Li Qinzai took the trouble to answer Qiao'er's various "whys".
Walking from the Wei River to Zhuangzi, passing by the field bank on the roadside, Li Qinzai paused, suddenly opened his eyes wide, and blurted out: "Damn, he's such a big man!"
There was indeed a person lying in a ditch beside the field.
This was a young man in his twenties, lying in the ditch covered in blood. His clothes were ragged and shabby, covered in blood, and he didn't know whether he was dead or alive when he fell in the ditch.
Li Qinzai's first reaction was not to save people. Instead, he picked up Qiao'er with one hand, covered Qiao'er's eyes with the other hand, and whispered: "Let's go home!"
"Dad, is that man dead just now? It's so cold, why is he lying in the ditch? Dad, should we save him?" Qiao'er asked a series of questions.
"Good boy Qiao'er, let's go home first and then decide whether to save him or not, okay?"
