Chapter 288: Call in the middle of the night!

Around 5:00, Ganlu Temple.
After Li Er had finished his dinner with his eldest grandson, he moved here and continued to work overtime.
As the emperor, Li Er's daily life is actually much more "hardened" than Li Zexuan. For him, "working overtime" is commonplace.
Quietly in the main hall, from time to time a cool summer breeze blows in, swaying with the candlelight on the wall, and occasionally there is a cry of grasshopper outside the hall, as if it is sending in this peaceful night. Song hymn.
About half an hour later, after reading the last memorial to Li Erbiao, he breathed a sigh of relief, leaning against the dragon chair a little tiredly, and then cast his gaze on the candlelight in the temple with a moment of wonder.
He was thinking about the telegraph that he saw in the workshop in the afternoon.
To be honest, the telegraph is a tool that can transmit information to each other more than a dozen miles apart. Before today, Li Er only felt that only the immortal family would have this kind of artifact, but today he not only saw it in person, but also this artifact. The maker turned out to be just a fourteen or five-year-old boy, which really subverted Li Er's cognition.
On the way back, although Li Er remained calm on his face, his heart was turbulent and it was difficult to calm down.
"Of course, this is only the possibility of being intercepted in theory, because the production principle of the telegraph is only proficient in the world!"
The words Li Zexuan said in the afternoon kept echoing in Li Er's mind.
Arrogance, there is no doubt that there is arrogance everywhere in this sentence, but people have arrogant capital!
Before Li Yuan was only Tang Guogong, Li Er, as the second son of the Guogong family, was not only taught by a famous teacher in martial arts, but also had certain accomplishments in literary cultivation. Therefore, the early Li Er was called a Both civil and military.
Although he did not study and break ten thousand books, his knowledge is absolutely impressive. Especially in the last years of the Sui Dynasty, Li Er followed Li Yuan's rebellion from Taiyuan and swept the world like a broken bamboo, finally set the tripod Central Plains, and now, he ascended the throne of God, he His identity has changed again and again, and he has risen step by step. Accordingly, his experience and knowledge have naturally become more and more extensive. Even so, he has never seen something like a telegraph, as well as the principle of the telegraph explained by Li Zexuan. , He was unheard of. He was quite sure that the knowledge Li Zexuan said had never appeared in the world.
"Not to mention the martial arts of this real spirit Xu, the best medical skills in the world, but the knowledge is still so profound, does this kind of person really exist in the world?"
At this moment, Li Er had a hint of curiosity, or suspicion, towards the real person Lingxu that he had never seen with his own eyes, and only existed by word of mouth.
"Could it be that he doesn't belong to the world? Then, does the knowledge shown by Li Zexuan come from the immortal family?"
Li Eryi was thinking wildly, and couldn't think of a reason. After a while, he suddenly said: "King Wei!"
Those who have been in contact with Li Zexuan more deeply and are familiar with his knowledge, Li Tai can be considered the top ranking, and Li Er decided to ask Li Tai carefully.
Previously, scooters, curved ploughs, paper machines, and compasses were all good to say. Although these things are ingeniously constructed, they are still within the scope of Li Er's understanding. However, the telegraph machine that Li Zexuan produced this time is a bit too... .. Too mysterious, yes, it is mysterious, as if this thing does not belong to this world.
It is for this reason that Li Er intends to ask questions carefully.
.......................
"My son has seen my father!"
About two quarters of an hour later, the chubby Li Tai arrived at the Temple of Ganlu. He can’t be blamed for this. Among the grown-up princes, Li Tai is a special case. Li Er specially allowed him to establish a mansion in Chang'an. This treatment is simply It was close to Prince Li Chengqian.
The Palace of the Wei Dynasty is still some distance away from the imperial palace, and at this time, all gates of the imperial palace are closed. Although the has a warrant from Li Er to take Li Tai into the palace unimpededly, he sits in a hanging basket all the way and crosses the palace wall. It also takes a lot of time.
"No gift, come, give a seat!"
When Li Er saw this chubby son, he couldn't help but feel happy. He had always been very fond of Li Tai, and apart from Li Tai's brilliant and brilliant, it might not have been related to Li Tai's very happy body shape.
"Thank you, Father!"
Although Li Tai didn't know what was wrong with Li Er calling him over so late, he believed that he hadn't done anything extraordinary recently, so he was certainly not imaginary.
"Qing Que, I call you late at night because I want to ask you something."
Li Er waved his hand and signaled the rest of the court ladies and eunuchs to retreat, and then the father and son exchanged routinely for a while, Li Er went straight to the topic and said.
"Father, please tell me, your sons and ministers will know all you can say!
"Well, Qingque, count the days. You go to the monitoring class of the country. It’s almost a month or so. I heard before that you have always been among the best in the arithmetic school. I am very relieved. I want to ask you today. What do you know about Li Zexuan's knowledge?"
When talking about Li Tai's achievements ~EbookFREE.me~ Li Er's face could not help but glow with a smug look. His son's grades are good, and I will be happy when I am an emperor, even if Li Er is an emperor.
Hearing Li Er's question, Li Tai couldn't help but frown. He didn't know what Li Er's question meant. After thinking for a long time, he replied:
"Back to my father, the longer I stayed with Mr. Li, the more I feel that my husband’s knowledge is like a sea of ​​knowledge. I only talk about arithmetic together. I am sure that no one in the world can defeat him in this respect. He proposed the concept , Method, Erchen later searched through all the ancient books and couldn't find it. In mathematics, Mr. Li should be his own family, and using his theory, problem solving is often faster and more accurate!"
When he said this, he was as proud as Li Tai, and his face couldn't help showing a trace of admiration.
This subtle expression was naturally caught by Li Er, and he couldn't help feeling a little surprised in his heart.
"What about other than mathematics? Have you ever understood Qingque?"
"Outside of mathematics?"
Li Tai glanced at Li Er curiously, he seemed to understand something.
"Speaking of Mr. Li's knowledge other than arithmetic, the most impressive thing about the children is that when he made a compass before, Mr. Li explained to us the hypothesis of the nature of the earth."
"Oh? The nature of the earth? What is the nature of the earth? Green bird, come and listen!"
Li Er couldn't help asking curiously.
"Back to the emperor, in order to explain to some of 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 still a big magnet..."
Li Tai slowly narrated the scene of that day, and Li Er listened carefully to the magic like a fairy tale, and the horror in his heart grew more and more.
