"There are two kinds, Huang Yu Ling vassal king, Bai Yu Ling Provincial Yuan Tai!" Cai Pengxi replied, "Topaz uses Hemo jade, and Baiyu uses Hetian jade. ”

The so-called Provincial Yuan Tai is the three central institutions of the Yuan Dynasty: Zhongshu Province, the Privy Council, and the Yushi Tai.

"Why haven't I seen anything about such an important thing?" Yu Yao was a little surprised.

"Because of these two kinds of holy decree jade plates, the holy decree issued is not a troop transfer order, but a major event for the crown prince! The Yuan Dynasty is a very special dynasty, such as the secrecy of the imperial tomb, such as the lack of some historical materials, and for example, the chaos of the succession to the throne!"

Cai Pengxi then explained, "This holy decree jade plate should have only been used by a few emperors of the Yuan Dynasty, and it was all secretly transmitted, so this situation occurred." That's why it's so rare, and not just in terms of antique value!"

Yu Yao thought to himself that the chaotic succession to the throne in the Yuan Dynasty was indeed a historical fact, especially after Kublai Khan. The political, economic, and cultural system of the Yuan Dynasty lagged behind that of the Han dynasty, and was inferior to that of the last Manchu feudal dynasty.

In the Yuan Dynasty, there was no such thing as an "eldest son", nor did it have the Eight Banners Conference and the secret decree of the first emperor like the Manchu Qing Dynasty, and the qualifications of the crown prince could be extended to all direct descendants of Genghis Khan.

The competition for the throne within the Yuan imperial family and with the four khanates has always been fierce, and the Yuan Dynasty had a period of less than 30 years when there were eight "emperors".

Therefore, as Cai Pengxi said, only a few emperors have used it, and it is also complementary to historical facts;

"Then how did you find out?" Yu Yao then asked.

Cai Pengxi waved his hand, "I also picked up the tooth wisdom of the master Lang Gong." ”

"Gong Lang told me that in his early years, he had the opportunity to get a white jade plaque of the Holy Decree, but unfortunately, he was preempted by Xie Liuzhai. Therefore, Lang Gong checked a large number of cultural relics and various historical materials, and thus deduced this conclusion, and some so-called historical materials may actually be just a few words or inscriptions on cultural relics. Therefore, it is normal for the Holy Decree Jade Plaque, even if it is a master in the antique circle, to be unheard of. ”

"No wonder. Yu Yao couldn't help but pick up the jade plate that Cai Pengxi put down, and at this time, he rubbed it between his fingers, and suddenly had a different feeling - this is a natural sublimation reaction of understanding the source and psychology.

That's the charm of antiques. Why are paintings and calligraphy the easiest to fetch high prices? Because they often leave the imprint of the author and collectors of previous generations, it is easier to create a sense of substitution of "dialogue with the ancients".

"Then where did this holy decree white jade plate end up? Yu Yao asked again.

"I don't know! Maybe it's sold, but the collector keeps it secret, or maybe it's been kept secret. Cai Pengxi shook his head, and then said solemnly, "You can already make a lot of money from this pigeon's blood red;

"Old man, I just don't have pigeon blood red, and I won't sell this jade card. Yu Yao responded.

At this time, Cai Zhihuang suddenly sighed, "Grandpa, you have never told me about this, but when I heard it today, I really felt lonely." ”

"I didn't have a phone before, so I didn't mention it. Cai Pengxi glanced at Cai Zhihuang, "Not only you, even if it was Lang Gong back then, there will be times when you feel lonely and unheard! Antiques are very widely related, and the knowledge required is as vast as a sea of smoke, and the sea of learning is endless!"

Cai Zhihuang seemed to be touched and fell into deep thought.

······

After Yu Yao and Cai Zhihuang agreed on some matters about pigeon blood red, they took their leave.

Yu Yao contacted Shangguan Yu again and went to pick up the patch together. In the evening, Yu Yao, Shangguan Yu, Yang Rui and Lin Fengcao met, and after dinner, they came to Lin Fengcao's residence.

Lin Fengcao's residence, not far from the school, is an ordinary closed community, with two bedrooms and one living room, and the furniture industry is very ordinary. However, there are still a few antiques in the study.

Yu Yao didn't look closely, because a pair of lampstands had been placed in the middle of the study.

Because the size of Shangguan Yu's patch is very different, so try it first, the comb teeth above and below the lampshade were originally stuck on the patch, but Shangguan Yu's patch can only be stuck below, and the top is not reachable, and it is short, and there is a gap of about two centimeters on the lampshade.

Try Yu Yao's patch again, it fits just right after a week, there is no gap, and the upper and lower comb teeth can be stuck, but it is still a little too short, completely stuck underneath, and the top is just barely stuck.

In fact, if it was supposed to be a pair of moon shadow lights, the patches should also be a pair, reflecting each other, but in the current situation, you can only try one first.

Naturally, I tried the patch of Yu Yao that was more suitable first.

Lin Fengcao had already prepared smokeless candles, lit them, and closed the lampshade. The thick two-layer curtains have been pulled to death, and even the door of the study has been sealed by Lin Fengcao. In the whole room, there was only candlelight in the lampshade.

There was no response for more than ten seconds.

But all four of them were able to hold their breath as well.

The candlelight is getting brighter and brighter······

"It's turned!" Yang Rui suddenly couldn't help but scream.

At this time, the lampshade did shake slightly, but it was not an obvious rotation.

"Maybe it's been too long, and it needs a warm-up process. Shangguan Yu responded.

After a little more than a minute, the lampshade finally began to rotate slowly, slowly and stuttering.

No images were seen in the surrounding area.

The lampshade is turning faster and faster. Of course, this is only relatively fast at the beginning, and the actual speed is still relatively slow. Finally, a constant tempo is reached, which is also a relatively slow rhythm.

After the lampshade rotated at a constant speed for about half a minute, light and shadow really began to appear all around!

At first it was mottled, then it gradually expanded, gradually merged, and gradually became clearer!

It's kind of like a slideshow.

The four of them seem to be surrounded by a scenery of rivers and mountains, with high mountains stretching and dense forests undulating with the mountains.

The red sun is rising, and its path is bright. The river flows out of the subterranean and flows into the ocean.

Because the patch rotates with the lampshade, if you only freeze at one place, the picture will move, and if you look at it with the speed and frequency of the lampshade, it seems to have a three-dimensional feeling.

Such a thing, in the face of modern technology, is actually not worth a penny. But this is something from hundreds of years ago, relying on only a lamp, a paper and a candle!

"It's amazing!" Yu Yao couldn't help but sigh.

At this time, Yu Yao found that in the picture, there was a scene that could not be seen on the patch!

The big river has a distant view of the sea on the patch, but on the small patch, this part of the scenery is not very clear, and it is at the end of both sides of the patch, which is "separated".

Now the patch is closed on the lampshade, and this part of the scenery is magnified, only to see a tall and relatively smooth cliff wall by the sea, with four characters engraved vertically.

The words are not very big in the light and shadow, and the light and shadow are not very clear, but if you look closely, you can still recognize them:

Give me back the rivers and mountains!
