Otaku Engineer in Great Tang Dynasty Chapter 288: Call in late night!

At around 5:00, the Temple of Ganlu.

After Li Er finished his dinner at the eldest grandson's place, he moved here and continued to "work overtime".

As an emperor, Li Er's daily life is actually much more "hard-worked" than Li Zexuan's. For him, "working overtime" is commonplace.

The main hall is quiet, and a cool summer night breeze blows in from time to time, swaying with the candlelight on the wall, and occasionally a grasshopper's call is heard outside the hall, as if for the peaceful night Send a hymn.

About half an hour later, after reading the last memorial to Li Erban, he breathed a sigh of relief, leaning against the dragon chair a little tiredly, and then cast his gaze on the candlelight in the hall for a while.

He was thinking about the telegraph machine he saw at the Trick Art 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 immortal figures would have this kind of artifact, but today he not only saw it in person, but also The creator of this artifact was only a fourteen or five-year-old boy, which really subverted Li Er's cognition.

On the way back, although Li Er was calm on his face, his heart was turbulent and it was difficult to calm down.

"Of course, this is only a theoretical possibility of being intercepted. Because of the production principle of the telegraph machine, only the minister is 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 this sentence is arrogant everywhere, but people have arrogant capital!

Previously, when Li Yuan was only Tang Guogong, Li Er was the second son of the Guogong family. Not only was he taught by a famous teacher in martial arts, but he also had certain accomplishments in literary cultivation. Therefore, the early Li Er was called It is both civil and military.

Although he did not study and break ten thousand books, his knowledge is absolutely remarkable. Especially in the last years of the Sui Dynasty, Li Er rebelled from Taiyuan along with Li Yuan, and swept the world like a broken bamboo, finally set the Ding Zhongyuan, and now, he ascended to God His identity has changed again and again, and he has risen step by step. Correspondingly, his experience and knowledge have naturally become more and more extensive. Even so, he has never seen such things as telegraphs, and he has never seen such things as Li Zexuan. He has never heard of the principle of the telegraph machine. He was quite sure that the knowledge Li Zexuan said had never appeared in the world.

"This spiritual mortal man has extraordinary martial arts and a world-renowned medical skill, but his knowledge is still so profound. Does such a person really exist in the world?"

At this moment, Li Er had a hint of curiosity, or suspicion, about the real spirit Lingxu who he had never seen with his own eyes, and only existed by word of mouth.

"Does he not belong to the world? Then the knowledge shown by Li Zexuan comes from the fairy family?"

Li Eryi was thinking about it, and he couldn't think of a reason. After a while, he suddenly said: "King Wei!"

People who have had a deep contact with Li Zexuan and are familiar with his knowledge. Li Tai is also considered the top ranking. Li Er decided to ask Li Tai carefully.

Previously, scooters, curved ploughs, paper machines, and compasses are all good to say. Although these things are cleverly constructed, they are still within the scope of Li Er's understanding. However, the telegraph machine that Li Zexuan has assembled this time is really too Too...too too mysterious, yes, it is too mysterious, as if this thing does not belong to this world.

It is for this reason that Li Er intends to ask carefully.

"My son has met 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 adult princes, Li Tai is a special case. Li Er specially allowed him to build a mansion in Chang'an. The treatment is almost equal to the prince Li Chengqian.

Wei Palace 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, he can take Li Tai into the palace unimpeded, but he sits in a hanging basket all the way. The palace wall also takes a lot of time.

"No gift, come, give a seat!"

Li Er can’t help but feel happy when he sees this chubby son. He has always been very fond of Li Tai. Apart from Li Taicong, he may not have the same body shape as Li Tai. related.

"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 of course he was right.

"Green bird, I call you late at night, I want to ask you something."

Li Er waved his hand and motioned to 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 children will know everything you can say!"

"Well, Qingque, count the days, you go to the monitoring class of the country, almost a month or so. I heard before that you have always been among the best in the school of mathematics. I am very relieved, I want to ask today Ask you, how much do you know about Li Zexuan's knowledge?"

When talking about Li Tai's achievements~IndoMTL.com~Li Er's face couldn't help showing 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 about it for a long time, he replied:

"Going back to the emperor, 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 mathematics. I am sure that no one in the world can beat him in this respect. The concepts and methods proposed by the children were not found in all the ancient books afterwards. In mathematics, Mr. Li should be his own family, and using his theory, problem solving is often faster and more accurate!"

Speaking of this, as proud as Li Tai, there was a hint of admiration on his face.

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 learned about Qingque?"

"Outside of mathematics?"

Li Tai looked 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 the compass before, Mr. Li explained to us the imaginary nature of the earth."

"Oh? The nature of the earth? What is the nature of the earth? Green bird, hurry up and listen!"

Li Er couldn't help asking curiously.

"Back to the father, Mr. Li used to explain to us why the compass can indicate the direction. He 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.
