"The earth is actually a round ball? And it's also magnetic?"
In the Manna Hall, after Li Tai told everything he went through when making the compass that day, Li Er's expression became a little complicated. After a long time, he couldn't help but murmur to himself.
These novel theories may sound absurd at first, but behind each theory, there are strong arguments to support it, making it impossible for you to refute it. It is precisely because of this that Li Er took a long time after listening to it. Silent.
"Qingque, it seems that you have already believed in the theory proposed by Li Zexuan?"
Li Er turned around and asked softly.
Li Tai had been sitting quietly below. Even though Li Er had been thinking for a long time, he did not show any impatience or make any sound. When he heard Li Er's question, he quickly replied:
"Indeed, Mr. Li's theory is not empty talk. There is a strong factual basis behind it. I also participated in one of the small experiments that day. The facts are before my eyes. I can't help but believe it."
Li Tai paused and then said:
"My son used to boast that he was talented and knowledgeable, but he was a bit arrogant. After meeting Mr. Li, my son realized what it means that there is heaven and there are people outside the world. In front of the Qiquge Pavilion, Mr. Li's inexplicable questions made my son confused. He was tortured to the point of leaving no trace of his body."
"Later, Erchen entered the Arithmetic School with some thoughts of competing. However, as the understanding deepened, he was impressed by the profound and vast knowledge of Mr. Erchen. A new door opened to Erchen. After I went in, I discovered that arithmetic can be so exciting, interesting, and novel!"
"It wasn't until a few days ago that my son understood that arithmetic is just the tip of the iceberg among the knowledge that my husband is good at. Physics and chemistry are all knowledge that my son has never heard of before. My husband can master them at his fingertips. What I learned before The thought of competing has long since disappeared without a trace."
Compared with two months ago, Li Tai is indeed more stable and sunny now. He is focused on his studies and has even vaguely forgotten about competing with Li Chengqian for favor.
Li Er looked at his son, who had changed so much in a short period of time, and felt a little emotional for a moment. After thinking twice about what Li Tai had just said, he suddenly asked: "Chemistry? What is chemistry? Qing" Que, you probably haven’t mentioned chemistry before, right?”
"Uh~~"
Li Tai was a little dumbfounded. He accidentally let it slip. He had promised Li Zexuan not to spread the principles of making glass to others. What should he do now?
"Huh~? What? Is there anything else you need to hide from me?"
Li Er was so shrewd that he immediately saw the hesitation in Li Tai's eyes. Doesn't hesitation at this time mean that he is preparing to lie next?
Li Er was a little dissatisfied. Among his several sons, the one he loved most was Li Tai. He didn't expect that his most beloved son would now want to lie to him.
"No, no, back to my father, sir, I said before that the so-called chemistry is the science of change, which is the study of material changes. Several substances can react with each other under certain conditions to generate a new substance. This is the definition of chemistry and what chemistry is for!”
Li Tai panicked at the look in Li Er's eyes and blurted out quickly.
"The science of change? This sounds interesting!"
Li Er held his chin and smiled, then asked: "Why would Li Zexuan mention this knowledge to you? Could it be that this guy has created something new?"
Li Tai's heart sank. Sure enough, things developed in the direction he least wanted to see. But in this case, there was no time left for him to think. The little fat man could only bite the bullet and said: "Go back to my father, sir. Hu Shang’s colored glaze was turbid and expensive, so he made his own colored glaze, and the knowledge he used was chemistry!”
"What~~?"
Li Er suddenly stood up. He was really shocked and angry. Li Zexuan made something as hugely profitable as Liuli on his word. How could he not be shocked? Previously, the imperial court commissioned the Qiquge Workshop to make a compass. Li Zexuan asked for a price of four thousand dollars because it contained colored glaze. He thought about it at the time and agreed. But now that Li Zexuan can make colored glaze himself, the cost of the compass will definitely increase. It's much cheaper. Thinking of this, how can Li Er not be angry?
Two days ago, Li Xiaogong excitedly ran into the palace and told him that the compasses he bought from the Qiquge Workshop were of better quality, especially the colored glaze was clearer. At that time, Li Er was still wondering whether Li Zexuan was a conscience. Did you find that the compasses specially given to the imperial court were made of fine glass? The results of it? He and Li Xiaogong were both teased by this kid!
"Qingque, do you know how much the colored glaze made by Li Zexuan costs? How is it made specifically?"
Li Erping calmed down and asked.
"Well, back to my father, Mr. At that time, he only told us the general principles of the glass production process, but did not go into the details. I am afraid that only a few core members of the workshop can know the specific process of glass production. As for them I don’t know how much the colored glaze costs to produce, but I think it may be cheaper than the colored glaze sold by Hu Shang, and the quality should be even better!"
Li Tai thought about his words and said. He knew what Li Er was thinking, it was just that he was a little unbalanced. He deliberately did not tell the materials used by Liuli, otherwise Li Er would definitely be even more angry.
"Hmm~~, I didn't expect this kid to be so knowledgeable and talented, he can even make Liuli!"
Li Er didn't hear the news that colored glaze was very cheap, and he felt a little better. But after thinking about it for a moment, he felt relieved. Li Zexuan could make colored glaze, which would be beneficial to the Tang Dynasty without any harm. He should really be worried. It's those Hu businessmen who are right. Li Zexuan makes money based on his ability. As an emperor, why should he care about the minutiae?
"What my father said is that the longer you stay with your husband, the more you will feel his erudition!"
Li Tai breathed a sigh of relief and nodded in agreement.
"Haha~! That kid has been making some noise recently. I'm afraid you don't know about it, Qingque?"
Li Er took a sip of tea and smiled.
"Oh? Sir, does he have any other inventions? I have been busy preparing for the monthly exams recently, but I haven't seen much of you! Father, can you tell me something?"
The little fat man's eyes lit up and he said hurriedly.
"Haha, in addition to the arithmetic, physics, and chemistry you just mentioned, that kid is also proficient in electricity, magnetic field, and advanced mathematics! The thing he made recently was based on these subjects!"
