Around Wu time, Ganlu Hall.
After Li Er had dinner at his eldest grandson's place, he moved here and began to continue "working overtime."
As an emperor, Li Er's daily life is actually much "harder" than Li Zexuan's. For him, "working overtime" is commonplace.
The hall was quiet. From time to time, a cool breeze of summer night blew in, swaying the candles on the wall. Occasionally, there would be a scream of grasshoppers outside the hall, as if to give a breath of fresh air to the peaceful night. Song of praise.
About half an hour later, Li Er finished reviewing the last memorial. He breathed a sigh of relief, half-leaned on the dragon chair with some fatigue, and then turned his gaze to the candlelight in the hall, feeling lost in thought.
He was thinking about the telegraph machine he saw at the Qiquge Workshop in the afternoon.
To be honest, before today, Li Er only thought that only people from the Immortal Family would have such a magical tool, a telegraph machine that could send messages to each other even if they were more than ten miles apart. But today, not only did he see it in person, but also the magical weapon was The maker turned out to be just a boy of fourteen or fifteen years old, which really subverted Li Er's perception.
On the way back, although Li Er's face was calm, his heart was in turmoil and it was difficult to calm down.
"Of course, this is only a theoretical possibility of being intercepted, because only Xiaochen is proficient in the production principles of telegraph machines!"
What Li Zexuan said in the afternoon kept echoing in Li Er's mind.
Arrogance, there is no doubt that this sentence is full of arrogance, but people have the capital to be arrogant!
When Li Yuan was just the Duke of Tang Dynasty, Li Er, as the second son of the Duke's family, was not only taught by famous teachers in martial arts, but also had certain attainments in literary cultivation. Therefore, the early Li Er could be called Both civil and military.
Although he did not read more than ten thousand volumes, his knowledge was definitely good. Especially in the late Sui Dynasty, Li Er followed Li Yuan in revolting from Taiyuan. They swept the world with great momentum and finally settled in the Central Plains. Now, he ascends to the throne of God. He His identity has changed again and again, and he has been promoted step by step. Correspondingly, his experience and knowledge have naturally become more and more extensive. Even so, he has never seen anything like a telegraph machine, and he has never seen the principles of a telegraph machine explained by Li Zexuan. , which he had never heard of. He was very sure that the knowledge Li Zexuan mentioned had never appeared in the world.
"Not only does this Master Lingxu have extraordinary martial arts skills and unparalleled medical skills, but he is also so knowledgeable. Does such a person really exist in the world?"
At this moment, Li Er had a trace of curiosity, or suspicion, about the real person Lingxu, who he had never seen with his own eyes and only existed in word of mouth.
"Isn't it possible that he doesn't belong to the human world? Then the knowledge that Li Zexuan has displayed, doesn't it come from the Immortal Family?"
Li Eryi was thinking wildly and couldn't think of a reason. After a moment, he suddenly said: "Pass it to King Wei!"
For those who had deeper contact with Li Zexuan and were familiar with his knowledge, Li Tai was considered to be at the top of the list. Li Er decided to ask Li Tai.
Previously, scooters, curved plows, paper machines, and compasses were all okay. Although these things were ingeniously constructed, they were still within the scope of Li Er's knowledge. However, the telegraph machine Li Zexuan built this time was a bit too... .. It’s too mysterious, yes, it’s mysterious, as if this thing doesn’t belong to this world.
It was for this reason that Li Er decided to ask clearly.
... ... ... ... ... ... ... ... ... ..
"My son has met my father!"
About two-quarters of an hour later, the chubby Li Tai arrived at the Manlu Palace. You can't blame him for this. Among the adult princes, Li Tai is a special case. Li Er specifically allowed him to build a mansion in Chang'an. This treatment is simply incredible. He is approaching the prince Li Chengqian.
Prince Wei's Mansion is still some distance away from the palace, and at this time, all the gates of the palace are closed. Although the eunuch who passed the order has Li Er's warrant, he can take Li Tai into the palace unimpeded, but he has to sit in a hanging basket and cross the palace wall all the way. It also takes a lot of time.
"No courtesy, come and give me a seat!"
When Li Er saw his chubby son, he couldn't help but feel happy in his heart. He had always been very fond of Li Tai. In addition to Li Tai's extraordinary intelligence, it may not have been related to Li Tai's cheerful body shape.
"Thank you, Father!"
Although Li Tai didn't know why Li Er called him over so late, he believed that he hadn't done anything extraordinary recently, and he certainly felt justified.
"Qingque, I called you here late at night because I want to ask you something."
Li Er waved his hand and signaled the rest of the palace maids and eunuchs to leave. Then the father and son exchanged greetings as usual for a while, and then Li Er went straight to the point and said.
"Father, please tell me. I will tell you everything you know, and I will tell you everything!"
"Well, Qingque, let's count the days. It's almost been more than a month since you went to the Imperial College to monitor classes. I heard before that you were at the arithmetic school and your grades were always among the best. I'm very pleased. I want to ask you today. Qingque, how much do you know about Li Zexuan's knowledge?"
When talking about Li Tai's achievements, Li Er's face couldn't help but glow with a look of pride. If his son's grades are good, I will indeed be happy, and Li Er will not be an exception even if he is an emperor.
Hearing Li Er's question, Li Tai couldn't help but frown. He didn't know what the meaning of Li Er's question was. He thought for a long time before answering:
"Back to my father's palace, the longer I stay with Mr. Li, the more I feel that Mr. Li has a vast amount of knowledge. When it comes to arithmetic alone, I am sure that no one in the world can defeat him in this aspect. The concepts he proposed , method, I later searched all the ancient books but could not find it. In arithmetic, Mr. Li should be in his own way, and using his theory, problem solving is often faster and more accurate!"
Speaking of this, Li Tai was so proud that he couldn't help but show a hint of admiration on his face.
This subtle expression was naturally caught by Li Er, and he couldn't help but feel a little surprised.
"What about other than arithmetic? Have you ever understood Qingque?"
"Besides arithmetic?"
Li Tai glanced at Li Er curiously, and he seemed to understand something.
"As for Mr. Li's knowledge other than arithmetic, what impressed me the most was the hypothesis about the nature of the earth that Mr. Li explained to a few of us when we were making compasses."
"Oh? The nature of the earth? What is the nature of the earth? Qingque, please tell me!"
Li Er couldn't help but asked curiously.
"Back to my father, in order to explain to us why the compass can indicate the direction, Mr. Li once said that the earth under our feet is a sphere, and the sphere itself is also a big magnet..."
Li Tai slowly told the story of that day. Li Er listened carefully to the miraculous story that was like a fairy tale, and the horror in his heart grew bigger and bigger.
