This question has been bothering Di Renjie for a long time, and he never thought that someone would be able to answer it, and he would still be so decisive.

Xi Guogong definitely wouldn't lie to him as a child, could it be that the speed of light is really 30,000 steps?

Han Chongwen also glanced at the sun in confusion, he didn't expect that there was really someone who could tell the speed of the light.

Di Renjie immediately asked, "That Duke of Xi Guo, how did you know?" Is there a way to measure the speed of light? ”

Hearing this question, Leng Feng suddenly had a black line on his face.

He knows the speed of light, but he really doesn't know how to measure it, and he's not a physicist, so it's rare to be able to remember this number!

"This problem is very difficult, I don't know how this speed is measured, but I can guarantee that this number is similar to the real result, how to measure the speed, it is estimated that the students who study physics will have to figure it out by themselves in the future."

No way, be honest about learning, Leng Feng doesn't want to fool students.

Han Chongwen said disdainfully: "You don't know the process of sealing, how can you swear to tell the students the answer directly!" There is no square of learned people. ”

Leng Feng said helplessly: "I don't blame me, the person who knew the sealing process is no longer alive, I only know the result, and it is already very good." ”

I'm sorry for modern physics, but the timeline has been staggered anyway, so it's okay to say you're dead!

Han Chongwen was helpless and patted Di Renjie's shoulder: "Now you believe that this is the Duke of Xi Guo!" ”

Di Renjie immediately nodded: "I believe it!" ”

After speaking, he immediately knelt on his knees and said to Leng Feng: "Gong Xiguo, I believe that you are the smartest person in the world, can you take me as an apprentice?" I want to be the second smartest person in the world! ”

Hearing Di Renjie say this, Leng Feng laughed: "What the second smartest person in the world, hurry up, I already have four apprentices to worry about, and one more of you will definitely be worse." ”

It's not a good thing for an apprentice to be smart. For example, Li Tai has now exhausted the little physics knowledge that Leng Feng knows, and has embarked on the road of independent exploration.

This Di Renjie was admitted to the Academy of Literature at the age of seven, which shows that his qualifications are definitely stronger than Li Tai. All the apprentices are like vampires, how can they be mixed up as masters!

Under the pull of Leng Feng, Di Renjie stood up. The little face that had been excited just now turned gray.

It was clearly rejected!

Leng Feng no longer paid attention to Di Renjie, and asked Han Chongwen instead: "I asked the Printing Workshop to help me print the new commercial tax law yesterday, why did they all excuse themselves and said that there was no schedule, and they postponed it to half a year later?" What is the printing of so much time wasted? ”

Han Chongwen grinned and said: "You don't know the efficiency of the printing workshop, it's not a big deal, can you postpone your business to half a year later?" At the beginning, the Literary Academy and the officials of various ministries of the imperial court wanted to write an encyclopedia of Zhenguan, and now, the writing has finally been completed. Such a huge book is definitely a hot seller, how can the printing shop not take this opportunity to salvage a sum! ”

Leng Feng laughed.

Reality! Reality can change many people, even Han Chongwen will inevitably become a "businessman" because of the Academy. You see how accurately he seized the opportunity, which is not something that ordinary businessmen can do.

Han Chongwen also knew why Leng Feng was laughing, and his old face couldn't help but turn red. There's no way, the students of the Quanquan Academy are counting on him to eat with pen and ink, how can he make more money if he doesn't want to do it?

Di Renjie saw that the two big men had finished talking, so he interjected and asked Leng Feng: "Duke Xi Guo, you really don't accept me as an apprentice?" ”

Leng Feng looked at Di Renjie, but still shook his head.

To be honest, he also wanted to accept Di Renjie, but with Li Tai, especially Wu Mei's experience, he was really afraid of the smart apprentice.

Seeing Leng Feng shaking his head, Di Renjie could only sigh and go back to the classroom, the next class was about to be. Compared with the little gentleman in the Academy, the old master of the Academy of Literature talked about much more profound things, and even he had a hard time following it. Competitive and competitive, he didn't want to give up his first throne.

After saying goodbye to Han Chongwen, Leng Feng went to the printing shop and got a brand new set of Zhenguan encyclopedias.

Due to the limitations of printing technology, the Zhenguan Encyclopedia could not be printed like a dictionary, but could only be a stack of fourteen books in a wooden box.

Zhenguan Encyclopedia, although its current role is a bit chicken, more like a sycophant of Li Shimin, but with the development of education, it will eventually play its effect.

After Bai took a set of Zhenguan encyclopedias, Leng Feng decided to keep it at home and treasure it. Anything that is old for years is worth anything. If you collect this first batch of Zhenguan encyclopedias, six or seven hundred years later, it will be no problem to change a house around Chang'an!

Holding the encyclopedia, Leng Feng returned home.

He has to go to work in the morning, and in the afternoon it is his personal time.

The two babies in the family are now supposed to read and write, and he, the father, has to take responsibility.

Just when Leng Feng was teaching Leng Jing and Leng Yuewu to recognize words, Lao Li knocked on the door and said, "Master, there is a post, and it is Shangshu Zuo Cheng Di Xiaoxu who sent the post." ”

"Di Xiaoxu? Who is this man? ”

Although Leng Feng has been the secretary of the military department for a long time, he doesn't know anyone in the court except for the big guy at the top, this Di Xiaoxu....

Could it be Di Renjie's father?

With questions, Leng Feng went out to greet Di Xiaoxu.

Although the identities of the two people do not match, but the official position of the person is not low, it is still a normal visit to send a post, and it is a manifestation of arrogance that he does not go out to greet him.

After a while, a simple carriage came by the door, proving the simplicity of the owner.

An old man with a bright head got down from the carriage, looking at his appearance, Leng Feng was sure that he must not be Di Renjie's father.

Di Xiaoxu arched his hand to Leng Feng and said, "It's really ashamed that the Duke of Lao Xi came to greet him!" ”

Leng Feng returned the salute: "It's a tradition for guests to come and treat the host, Di Zuocheng is coming, how can I wait in the house." ”

After speaking, Leng Feng invited Di Xiaoxu into the cold mansion.

After the two of them sat down in the living room, Di Xiaoxu directly explained his intentions: "Gong Xi Guo, Di Renjie of the Academy of Literature, is the second grandson of Xia, today he asked for leave to return to the mansion, but he was looking for a good cry!" ”

Leng Feng smiled bitterly, Di Renjie probably said that he was rejected for apprenticeship.

Sure enough, Di Xiaoxu continued: "Duke Xiguo, Renjie, this kid is very smart and admires you, why don't you want to take him as an apprentice? ”

Di Xiaoxu didn't think that Leng Feng looked down on their Di family, as far as he knew, the fourth apprentice of the Duke of Xi Guo was the girl of the late Ying Guogong Wushi Tong.

It stands to reason that famous teachers should like smart students, how....
