"The Earth is actually a sphere? And it's magnetic? "
In the Sweet Nectar Hall, Li Tai finished recounting everything that had happened when he made the compass. Li Er's expression became somewhat complicated, and after a long time, he couldn't help but mutter to himself.
These novel theories might sound absurd at first, but behind each theory, there was a strong argument supporting it, making it impossible to refute. It was precisely because of this that Li Er was silent for a long time after listening to it.
"Qingque, it seems that you already believe in Li Zexuan's theories?"
Li Er turned around and asked softly.
Li Tai had been sitting quietly below. Even though Li Er had been deep in thought for a long time, he didn't show any impatience, nor did he make any sound. Now that he heard Li Er's question, he hurriedly replied:
"Indeed, Mister Li's theories are not empty words. There is a strong evidence behind them. Your son also participated in one of the small experiments that day. The facts are right in front of your son's eyes. Your son has no choice but to believe it."
Li Tai paused, then continued:
"Your son used to be conceited about his innate intelligence and erudite knowledge. Unavoidably, your son was a little arrogant because of his talents. Ever since I met Mister Li, your son has learned that there is always someone better than you. In front of the Curious Pavilion, Mister Li's inexplicable ten questions completely destroyed your son.
"Later on, your son entered the School of Mathematics. Originally, your son had some thoughts of competing with you, but as your son's understanding deepened, I was convinced by Mister's vast and profound knowledge. A new door opened to your son. After your son entered, your son discovered that mathematics could actually be so exciting, interesting, and novel!
"It wasn't until a few days ago that your son understood that mathematics was only the tip of the iceberg of Mister Li's expertise. Physics, chemistry, these are things that your son had never heard of before, but Mister Li was able to easily grasp them. Your son's previous thoughts of competing with you have long disappeared without a trace."
Compared to two months ago, Li Tai was indeed much more stable and sunny. He, who was focused on his studies, had even faintly forgotten that he had to compete with Li Chengqian for favor.
Li Tai looked at his son. In such a short period of time, he had changed so much. For a moment, he felt a little emotional. After mulling over what Li Tai had just said, he suddenly asked, "Chemistry? What is chemistry? Qingque, you haven't mentioned chemistry before, have you? "
"Eh ~ ~"
Li Tai was a little dumbfounded. He accidentally spilled the beans. He had promised Li Zexuan that he would not spread the principle of making glass. What should he do now?
"Hmm? What? Is there something else you need to hide from me? "
Li Tai was shrewd. He immediately saw the hesitation in Li Tai's eyes. Hesitation at this time was equivalent to preparing to lie.
Li Er was a little dissatisfied. Among his sons, Li Tai was the one he doted on the most. He did not expect that his favorite son would want to lie to him now.
"No, no. Replying to Imperial Father, the teacher said before that the so-called chemistry is the study of changes. It is a knowledge that studies the changes of substances. Under certain conditions, several substances can react with each other and form a new substance. This is the definition of chemistry and also the use of chemistry! "
When Li Tai saw Li Er's gaze, he panicked and hurriedly blurted out.
"The study of changes? This sounds interesting! "
Li Er held his chin and smiled, then asked, "Why did Li Zexuan mention this knowledge to you? Could it be that this kid has created something new? "
Li Tai's heart sank. Sure enough, things were developing in the direction he did not want to see the most. However, in this situation, there was no time for him to think. The little fatty could only bite the bullet and say, "Replying to Imperial Father, previously the teacher felt that the Hu merchant's glass was turbid and expensive, so he made his own glass. The knowledge he used was chemistry!"
"What ~ ~?"
Li Er suddenly stood up. He was shocked and angry. How could he not be shocked that Li Zexuan could make something like glass that was so profitable? Previously, the imperial court had commissioned the workshop of the Curious Pavilion to make compasses. Li Zexuan had asked for a high price because it contained glass. At that time, he thought about it and agreed. However, now that Li Zexuan could make his own glass, the cost of the compasses would definitely be much cheaper. Thinking of this, how could Li Er not be angry?
Two days ago, Li Xiaogong had excitedly ran into the palace to tell him that the compasses bought from the workshop of the Curious Pavilion were of better quality, especially the glass that was clearer. At that time, Li Er was still wondering if Li Zexuan had found his conscience and specially used good glass for this batch of compasses for the imperial court. In the end? He and Li Xiaogong had been teased by this kid!
"Then Qingque, do you know how much the glass Li Zexuan made cost? How exactly was it made? "
Li Er calmed himself down and asked.
"Erm, replying to Imperial Father, at that time, Mister only told us the general principle of the process of making colored glaze. He didn't talk about the details. I'm afraid that only a few core members of the workshop know the specific process of making colored glaze. As for the cost of the glass they make, your son does not know, but it should be somewhat cheaper than the glass sold by the Hu merchants, and the quality should be even higher! "
Li Tai considered his words as he spoke. He knew what Li Er was thinking. He was just a little unhappy, so he intentionally did not mention the materials used to make glass. Otherwise, Li Er would definitely be even angrier.
"Mm ~ ~ I didn't think that this kid would be so erudite and talented. He could even make glass!"
Li Er did not hear that the glass was very cheap, so he felt a little better. But after thinking about it for a while, he relaxed. Li Zexuan being able to make glass was only beneficial to the Great Tang. The ones who should be worried were the Hu merchants. Li Zexuan earned money with his own ability. As the Emperor, why should he care about such details?
"Imperial Father is right. The longer I stay with Teacher, the more I can feel Teacher's erudition!"
Li Tai heaved a sigh of relief and nodded in agreement.
"Heh ~! That kid has been up to something recently. Qingque, you probably don't know, right? "
Li Er took a sip of tea and smiled.
"Oh? Did Teacher invent something again? Your son has been busy preparing for the monthly examination and did not see Teacher! Can Imperial Father tell me a little? "
Little Fatty's eyes lit up as he hurriedly said.
"Hehe, other than the mathematics, physics, and chemistry that you mentioned just now, that kid is also proficient in electricity, magnetic fields, and advanced mathematics! The thing he made recently was made based on these few fields of knowledge! "
