Shangshu, a popular version of the annotations to the thirteen classics, is divided into Jinwen Shangshu and pseudo ancient Shangshu.

In fact, it's easy to understand.

The book Shangshu was lost long ago in the Western Jin Dynasty. Later, in Archaeology and from a few words of previous dynasties, Shangshu after the Western Jin Dynasty is actually a pseudo Shangshu, also known as Jinwen Shangshu.

Before the Western Jin Dynasty, Shangshu was the real ancient Shangshu.

Zhang Feng was in college before. He was fooled that the sister of the Department of ancient literature was very positive, so he foolishly took this course.

But once I went, I was stupid.

There are only three people in this class.

And they are both rough men, plus a dinosaur sister, which makes him how many grass mud horses he has in his heart?

But it's too late to want to run. After all, as long as you take an elective course, you need to calculate credits when you graduate. Coupled with the female professor, you finally see a normal human who is willing to come to this elective course. You can't help but take Zhang Feng as a baby pimple and take care of him.

However, at that time, Zhang Feng only thought that this course was about immortality and death.

But up to now, he really has to thank the female professor. If he hadn't forced him to instill knowledge of ancient Chinese at that time and didn't say anything else, such as family names, three character classics, etc., as well as the 18 times of Hu eggplant, which was also specially studied by the sister of the music department next door, he couldn't have learned it.

Although he also signed up for music elective courses.

But now it seems.

He was so excited that he had to find a painter to draw a portrait of a professor and offer incense three times a day.

However, in order not to shock the world, Zhang Feng had to give up.

After all, in this era, if anyone knows that your teacher is a woman?

Then you're finished.

Therefore, Zhang Feng was so excited when he saw the book of history, which had not yet revealed its true face.

He dares to conclude that this thing must be the ancient book of history!

Zhang Feng didn't ask where Li Yuan came from. Looking at the silk rusted with beautiful auspicious clouds, we can see that this thing is extraordinary. If it were Jinwen Shangshu, what kind of things in Lan street need to be cherished like this?

It can only be said that there is something wrong with the old man.

At this time, when Zhang Feng's hand was about to touch Li Yuan's embroidered robe, Li Yuan smiled.

After the destruction of the Sui Dynasty, he found it among the treasures of a great Confucian school in the Sui Dynasty.

He also knows the value of this thing, but it's always hidden in the book collection. It's not a thing. Now he wants to take it out to see if the boy knows the goods or not. More importantly, he wants to revenge one arrow.

After all, after being forced by Zhang Feng several times, Li Yuan was furious.

Seeing Zhang Feng's appearance, Li Yuan felt incomparable comfort all over his body!

"Boy, you should know what's precious about this thing, but you should understand that this thing can't be given lightly. Moreover, when I got this thing, I almost spent most of my family property. Otherwise, at this time, I don't pay attention to Guan Longba!"

Zhang Feng was surprised at the speech.

At this time, it is even more precious.

That's an exaggeration.

Although he can hear that Li Yuan is exaggerating, can he despise Guan Long?

Are you bragging?

If people do something, they can make Yang Guang, emperor of the Sui Dynasty, die or live. Otherwise, there will be nothing wrong with Li Tang. You told me that if you don't buy this thing, you will despise Guanlong group?

You're blowing up!

Do you think you are the Li surname in Longnan with five surnames and seven Wangli?

But Zhang Feng didn't dare to say it directly. He could only frown and say, "the old man's cowhide, such a good thing, must be that the ancient book of history is true?"

"Hahaha, you know the goods!"

When Li Yuan heard the speech, he laughed and stroked his beard.

Zhang Feng pulled the corners of his mouth and watched Li Yuan slowly untie the bag with the silk bag. At the next moment, a roll of bamboo slips with slightly brownish red and slightly dark color leaked out slowly. Although the silk thread connecting the bamboo slips had been replaced with a new one at this time, from the color of the bamboo slips, this thing is the ancient text Shangshu!

This is the real baby.

If we can get it, the reputation of Bailu academy will soar in an instant.

But until this time, Li Yuan didn't say what he wanted. Instead, he said how hard he got it.

This let Zhang Feng know that it is more difficult to get this thing.

Zhang Feng couldn't help sighing and forbearing to see the bamboo slips made by Li Yuan. "Although I know the value of this thing, there's an old saying that a gentleman doesn't take advantage of others! So, it's just that I can see you today. It's also a great blessing in life."

Li Yuan was stunned.

Looking at Zhang Feng who turned his face faster than the book in surprise, he asked, "boy, this is the authentic work of ancient Chinese Shangshu! Don't you want it?"
