"The earth turned out to be a ball? And it is also magnetic?"

In the Ganlu Temple, after Li Tai told everything he had experienced when making the compass that day, Li Er's complexion became a little complicated. After a long time, he couldn't help muttering to himself.

These novel theories may sound absurd at first, but behind each theory, there are powerful arguments to support it, so you can't speak up if you want to refute it. Because of this, it took a long time after Li Er listened to it. Silently speechless.

"Qing Que, it seems that you already believe the doctrine proposed by Li Zexuan?"

Li Er turned around and asked softly.

Li Tai had been sitting down quietly before. Even though Li Er had been meditating for a long time, he did not show any impatience, let alone make any sound. At this time, he heard Li Er's question and quickly replied:

"It is true. Mr. Li's theory is not just empty talk. There are strong facts behind it. The son-chen also participated in a small experiment that day. The facts are in front of him, and he can't help him not believe it."

Li Tai paused, then said:

"Erchen used to be arrogant and intelligent, knowledgeable and talented. He was a little bit arrogant. After meeting Mr. Li, he knew what is a heaven and a man. There are people outside of the world. In front of the door of Qiqu Pavilion, Mr. Li’s inexplicable ten questions. The body of abuse is not complete.

Later, Erchen entered the School of Mathematical Studies. He had some thoughts of superiority, but as his understanding deepened, he was overwhelmed by his profound knowledge. A new door opened to Erchen. After entering, I realized that mathematics can be so exciting, interesting and novel!

It was not until a few days ago that my son understood arithmetic. It turned out that it was only the tip of the iceberg in the knowledge that my husband was good at. Physics, chemistry, these knowledges that my son had never heard of before, my husband could easily come to him. The higher mind has long since disappeared without a trace. "

Compared to two months ago, Li Tai is indeed more stable, more sunny, and focused on learning. He has even forgotten to fight for favor with Li Chengqian.

Li Er looked at his son. In a short period of time, the change was so great, and he felt a little emotional for a while. After pondering what Li Tai had just said twice in his heart, he suddenly questioned: "Chemistry? What is chemistry? You haven't mentioned chemistry before, have you?"

"Uh~~"

Li Tai was a little dumbfounded, and he accidentally said that he missed his mouth. He had promised Li Zexuan not to spread the principle of glass making before. What can I do now?

"Huh~? Why? Is there anything else that needs to be kept from me?"

How shrewd Li Er is, he immediately saw the hesitation in Li Tai's eyes. Isn't hesitation at this time equivalent to preparing to lie next?

Li Er felt a little dissatisfied. Among his sons, Li Tai was the one he loved the most. He didn't expect that his favorite son, now he wanted to lie to him.

"No, no, back to my father, my husband said before that the so-called chemistry is the science of change, which is the study of substance change. Under certain conditions, several substances can react with each other to form a new substance. This is the definition of chemistry and the purpose of chemistry!"

Li Tai was flustered by Li Er's eyes, and quickly blurted out.

"The study of change? This sounds interesting!"

Li Er held his chin and smiled, and then asked, "Why did Li Zexuan tell you about this knowledge? Could it be that this kid has created something new?"

Li Tai's heart sank. As expected, things were developing in the direction that he least wanted to see, but in this case, there was no time for him to think. Li Tai could only bite the bullet and said, "Going back to the father, Mr. Hu Shang's colored glaze was muddy and expensive, so he made colored glaze himself, and the knowledge he used was chemistry!"

"What~~?"

Li Erhuo Ran got up, he was really surprised and angry. Liuli was able to make such a profitable thing by Li Zexuan. This made him not surprised; the court commissioned the Qiquge workshop to make a compass. Including the reason for the colored glaze, the asking price was consistent. He thought about it at the time and agreed, but now Li Zexuan can make colored glaze by himself. The cost of the compass will definitely be much cheaper. Thinking of this, how is Li Er not angry?

Two days ago, Li Xiaogong rushed into the palace and told him that the compasses bought from the Qiquge workshop were of better quality, especially the colored glaze. At that time, Li Er was still wondering whether Li Zexuan was a conscience. What about the use of fine glass for this batch of compasses dedicated to the court? The results of it? He and Li Xiaogong were molested by this kid!

"Then Qingque, do you know the cost of the colored glaze made by Li Zexuan? How exactly is it made?"

Li Erping recovered his mood~lightnovelpub.net~ and asked.

"Um, back to the emperor, at that time, we only talked about the general principles of the colored glaze production process, but the details were not mentioned. The specific process of the colored glaze production is probably only known to the core members of the workshop. The cost of the colored glaze produced is unknown to the children, but I think it might be cheaper than the colored glaze sold by Hu Shang, and the quality should be even higher!"

Li Tae considered his words and said. He knew what Li Er was thinking, it was just that he was a little unbalanced. He deliberately didn't say the materials used by Liuli, otherwise Li Er would definitely be even more angry.

"Well~~, I didn't expect this kid to be really knowledgeable and talented, Liuli can make it!"

Li Er didn’t hear the news that Liuli was very cheap, so he felt a little better, but when he thought about it, he was relieved that Li Zexuan can make Liuli, for Datang, it is profitable and harmless. What really should be worried about is Those Husbands are right. Li Zexuan earns money by his ability. As an emperor, why should he care about the minutiae?

"What the emperor said is that the longer you stay with your husband, the more you can feel his erudition!"

Li Tai sighed in relief and nodded in agreement.

"Heh~! That kid has been moving recently, are you afraid that you don't know Qingque?"

Li Er took a sip of tea and smiled.

"Oh? Is there any invention of Mr.? My son has been busy preparing for the monthly exam recently, but I haven't seen him much! Can my father tell me one or two?"

The little fat man's eyes lit up and said hurriedly.

"Hehe, in addition to the arithmetic, physics, and chemistry you just said, what kind of electricity, magnetic field, and advanced mathematics is the kid also proficient in! This thing he did recently is based on these subjects!"
