"What's wrong?" asked Yu Yao.

"The bottom of the mortise seems to have been engraved, but it is too small to see clearly. Mao Ye said, put down the wooden box, got up and went to the side, and opened the toolbox.

Yu Yao couldn't help but pick it up and look at it, the bottom of the mortise seemed to have some nicks, but it was too small, and it was really not clear.

Mao Ye took a strong flashlight and a magnifying glass, and looked at the tenon.

After reading one, and then another, until all three were finished, Mao Ye picked up a pencil, pulled over a blank piece of paper, and sketched on it.

Mao Ye drew a total of three figures, all of which were very simple, and they were all irregular threads.

It's a lot like the threads on that octagonal plank.

"At the bottom of the mortise and tenon, what are you carving this?" Mao Ye frowned at the three figures.

Yu Yao looked at the three figures, "Master Mao, this seems to be able to be 'spelled' together." ”

"What?"

"You see, the threads on each diagram are about the same, but each has a dot on it, and the position of this dot is different······"

When Mao Ye heard this, he immediately picked up the eight-sided wooden block with threads, and from the threads of this wooden block, he really found three points, in different positions.

The so-called three points are actually the places where the three threads are interrupted, and there is a small independent protrusion.

Mao Ye pressed these three points separately with his fingertips, and there was no sign of loosening, which was part of the thread.

"I see! There is a point at the top, middle, and bottom, which refers to the direction of rotation! From the top point, to the middle point, to the bottom point, you can twist it in this direction; from the bottom, it is exactly the opposite, and the hands are twisted in the opposite direction together!"

"This is too finely done! plus the carved threads, the gap between the upper and lower butts is really not visible!" Yu Yao sighed.

Mao Ye didn't dare to push too hard at first, he stretched his strength, first a little temptation, but after slowly adding force, he didn't add too much, and then he loosened.

Slowly twisting, a gap appears in the middle of the octagonal wooden block, which slowly expands.

It turns out that there is a layer of threads inside, and you can see that there is a very fine powder on it, and at the same time, there is a faint smell of pine.

"Rosin?" Yu Yao asked.

"It's not rosin, rosin is non-slip, if it's rosin, it's been so long, it won't be so easy to twist. Mao Ye shook his head.

"I see, amber powder! it's not sticky, and at the same time it doesn't make the crevices obvious. Yu Yao said.

"Yes!" said Mao Ye, who had already divided this eight-sided wooden block into two!

In the middle of this block, there is a rectangular groove, which is stuffed with cotton wool.

The cotton wool was pulled out, revealing something wrapped in white silk, which looked rectangular and much smaller than the groove.

Open the white silk, and inside is a rectangular jade plaque!

It is more than seven centimeters long and about three centimeters wide.

"No wonder!" exclaimed Mao Ye.

"yes!" Yu Yao nodded.

What Mao Ye means is that it is no wonder that it doesn't look like there is something in it, and there is nothing unusual in weight. Yu Yao saw the situation inside, and naturally understood what Mao Ye meant.

The specific gravity of jade is definitely larger than that of wood, but the wood is too hollow and stuffed with cotton wool, and the small jade plaque just makes up for the weight of the wood with the hollow cotton wool.

"Is this Hetian Topaz? What is engraved on it?" Mao Ye pointed to the strange words on the jade plate, but he didn't get started, this is Yu Yao's thing, and it is jade, so he can't get started easily.

This rectangular jade plaque is indeed yellow, with rounded corners polished. There is a round hole at the top, which is not like a small hole in an ordinary jade plate, but a large hole with a diameter of nearly two centimeters. The walls of the holes are also polished and smooth.

On the jade plaque, two columns of text are engraved vertically. The lettering method is rare, a bit like the current art word, which is composed of two yin lines. The text content is indeed very special, it is definitely not Chinese characters, it is a bit like minority writing, but it is not like the common ones.

"It's not Hetian jade, this is Hemo jade, which is produced in Mongolia and the northeast, but the composition is similar to Hetian jade, mainly tremolite. Moreover, it is extremely rare to be able to achieve this kind of yellow! It is generally yellow and white, but this goose yellow is deeper!"

Yu Yao picked up the jade plaque and looked at the back, there were also two columns engraved on the back, which was also this kind of text, but the content was different.

"This text is so weird, I don't know it!"

"This is a jade plaque from the Qing Dynasty?"

Yu Yao shook his head, "It should be early, like the Yuan Dynasty." By the way, that blue and white wine pot is also from the Yuan Dynasty, maybe these two things are the same in the Qing Dynasty······"

"What? What did you kick and shatter the Yuan Qinghua wine jug? and only lost 5,000?" Mao Ye didn't know much about things other than woodware, jade plates, and porcelain, and was startled when he heard Yuan Qinghua.

"The folk kilns of the Yuan Dynasty, inferior goods, were not worth much. Yu Yao explained two sentences simply, but his eyes never left the words on the jade plate, "The ······ of the Yuan Dynasty"

"Seems to be able to find it!" Yu Yao immediately took out his mobile phone and searched for it.

Mao Ye said to himself, "The one on this jade plate can't be a ghost drawing talisman, it's a ······ for psychics."

"Sure enough!" Yu Yao pulled up the pictures he found, "Look!"

Mao Ye looked at it, and the picture was a blue-yellow metal plate, also with holes, and the orifice was also inlaid with a circle. There are also two columns of text on the card, which are exactly the same as the jade card!

Yu Yao scratched the picture, it was the reverse side of this brand, and the engraved text was the same as on the jade plate!

"What the hell is this?"

"On the picture is a gold medal of the holy decree of the Yuan Dynasty, which is used to transmit the holy decree and is generally used for the holy decree of troop transfer. ”

"Is this true? not like pure gold. ”

"It's not pure gold, it's mainly gold mixed with silver, because pure gold is too soft and easy to deform. It must be true, this gold medal of the Holy Decree, with a clear origin and authority, is now in the museum!"

"Then your current piece is the Holy Decree Jade Plate?"

"It should be!" Yu Yao put down his phone and tapped his forehead, "However, there have been gold medals and silver medals of holy decrees in the Yuan Dynasty, but I have never heard of the jade medals of holy decrees······"

"What kind of writing is engraved on this, and what does it mean?"

"This is the Paspa script, which was coined during the reign of Kublai Khan, which basically means: With the power of immortality, the Holy Emperor is inviolable, the emperor's orders cannot be disobeyed, and anyone who does not obey will be punished by death."

"Oh!" Mao Ye pondered, "If this is such a thing, it is indeed not suitable for jade! It is easy to break! This can't be someone who made it himself according to the holy decree gold medal, right?"

Yu Yao shook his head, "It shouldn't be." How can ordinary people see the gold medal of the Holy Decree? Moreover, even if they have seen it, it is impossible to master the Pas-Pa language!"
