"ah……"

When he saw Wang Guan opening the iron box, Yu Feibai was stunned and his eyes seemed to burst out.

"Haha, it seems that this lock has become somewhat decayed after hundreds of years of erosion. After a few random touches, the lock cylinder became loose and opened." Wang Guan smiled. In fact, he used his special ability to cheat.

After seeing the entire structure inside the lock through the pores, I easily opened the iron box.

At the same time, this explanation barely convinced Yu Feibai, but he also sighed a little, shook his head and said: "If I had known it, I wouldn't have to prepare so many tools. In order to collect these tools, I was sneaky, as if I was a thief.

Yes, I was questioned many times by the old man."

"Thank you for your hard work." Wang Guan also felt the same way.

After all, the origin of this iron box seems a bit shady. Therefore, when he was in the nursing home, he clearly had this ability, but he didn't dare to open it. He was afraid that the nurses who came to inspect from time to time would find out. It was difficult to explain.

clear.

"Now, it's finally done. Stop talking nonsense and take a quick look at what's in the box." Yu Feibai said eagerly, staring straight at the iron box, as if looking through the autumn water.

"good……"

Wang Guan was no exception. With a bit of excitement, he gently opened the slightly popped lid. Suddenly, the air circulated, and a dull breath came out, forming a vortex in the air.

"Ahem..." Fine dust hit their faces, and they were caught off guard, choking a little. However, neither of them had any intention of avoiding it. They just blinked and continued to look down at the iron box.

If this was a movie scene, or a plot in a martial arts novel. When the iron box was opened, either a concealed weapon would be ejected, or poison would be sprayed out. The two of them had no defense, so they would probably die.

Of course, the two of them were not so unlucky, so they saw very smoothly that there was no gold or silver treasure as expected in the box, but two different items were quietly placed on one side.

The long object was at the bottom of the box, tightly wrapped with strips of cloth. The square object was on top, also wrapped with a piece of yellow silk. The two of them couldn't see clearly what the two objects were.

After taking a second look, Yu Feibai was not disappointed. Instead, his voice trembled slightly as he said, "Wang Guan, I have a feeling that we seem to have discovered something incredible."

"What should I say?" Wang Guan asked casually, taking a gentle breath to calm down his agitated mood.

"Have you seen the dark dragon pattern on the yellow silk?" Yu Feibai said softly: "The yellow silk with the five-clawed golden dragon pattern must not be used casually in ancient times. I once saw a piece of it in the Palace Museum, which was specially used for wrapping.

Of jade seal."

"Jade seal?" Wang Guan was surprised, and then overjoyed. He looked at the square object carefully, and the more he looked at it, the more he felt that it was a box. Maybe there was something as valuable as a jade seal in the box.

"Isn't that right? You'll know just by looking at it."

While speaking, Yu Feibai reached out and took out the square object wrapped in yellow silk. Then, he carefully peeled off the silk. Suddenly, a lacquered gold box appeared in front of their eyes.

At the same time, Yu Feibai did not take a closer look at the box, but eagerly opened the lid. Suddenly, a crystal clear brilliance shone out of the box. Then, the brilliance was restrained and the warm color returned.

"It's really a jade seal." Yu Feibai said excitedly, his hands trembling slightly as he carefully took out the contents of the box.

Wang Guan looked carefully and saw that this square jade seal was carved from blue and white jade. The pure white color was as white as fat, with a bit of the brightness of clear blue water. Above the jade seal, there was a crowned tiger head button.

.The tiger head has a vivid image, the tiger's eyes are bright, the tiger's temples are spread out, and it is majestic.

Seal is actually a seal. Before the Qin Dynasty, seals, seals, seals, dragon buttons, tiger buttons, and unicorn buttons were not clearly divided. However, when Qin Shihuang unified the country, it was clearly stipulated that only the big seal used by the emperor could be used.

It can be called Xi, but no one else is allowed to use this title.

From then on, the seal became the unique term for the emperor's seal. Zhang Xianzhong also founded the country and proclaimed himself emperor, and his seal could barely be called a seal. Of course, now we need to confirm whether this square jade seal belongs to Zhang Xianzhong

thing.

"Look at what's printed on it."

At Wang Guan's reminder, Yu Feibai quickly turned over his hand and turned the jade seal upside down to look at it. He saw that there were four characters engraved in seal characters on the seal surface. However, because the characters were reversed, and there were also residues on the seal surface,

Some bright red ink pads covered the words, so they couldn't make them out for a while.

"Bring the paper, let me print it." Yu Feibai said quickly.

"Where is the paper..." Wang Guan looked around and suddenly found a glass mirror on the bedside. He had an idea and hurriedly took the mirror over and took a look at the printed surface.

Anyway, after a sway, the words of Jade Seal immediately appeared on the mirror.

"The Treasure of the Great West!" Yu Feibai read out the seal characters one by one, and immediately said with surprise: "As expected, this is really Zhang Xianzhong's jade seal."

In addition to being excited, Wang Guan also smiled and said: "You are so sure, you are not afraid that it is a fake."

"Fake? Impossible." Yu Feibai shook his head.

"Oh, are you so sure?" Wang Guan was a little surprised. You know, he may use his special ability to identify the authenticity and approximate age of the jade seal. However, Yu Feibai does not have this ability.

If you can tell whether a jade seal is authentic or fake based only on the seal of "Treasure of the West", then just take a random piece of jade, carve it into the shape of a large seal, and then engrave the seal on it, and you will see jade seals all over the streets.

"Of course." Yu Feibai nodded seriously and said with a smile: "Unless the story you said about digging for treasure in the mountains is a story made up to deceive me. Otherwise, all kinds of evidence show that this thing is definitely authentic.

"

"That's how you calculated it." Wang Guan was a little disappointed, thinking that Yu Feibai could make a detailed and clear identification from the jade seal itself. In this way, he could also learn some knowledge from it.

"What kind of expression are you looking at?" Yu Feibai said dissatisfied: "It's a treasure map, a large sum of money from the King of the West, and the tiger's power token. It's a clear context. Isn't this enough?"

"Not enough." Wang Guan shook his head and said: "If, without other supporting evidence, you just get this jade seal, can you identify its authenticity?"

"How can there be so many ifs in the world?"

After complaining, Yu Feibai said confidently: "However, don't underestimate me. At least, I can conclude that this jade is truly top-grade jade. Do you know what kind of jade material this is?"

"Hetian jade?" Wang Guan guessed.

"No, it's Nanyang Dushan Jade."

Yu Feibai said with some pride: "Hey, don't guess all the jade is Hotan jade. Although most of the imperial seals of the past dynasties were carved from Hotan jade. However, there are occasional exceptions."

"In the past two days, in order to find out the origin of the Huwei token, I have been checking Zhang Xianzhong's information."

After a pause, Yu Feibai continued to smile and said: "The three famous jade in China are Hetian jade, Xiuyan jade and Dushan jade. Among them, only Du jade is produced in the hinterland of the Central Plains. Judging from the war-torn and turbulent situation in the late Ming Dynasty,

Zhang Xianzhong may be able to grab it, whether it is Japanese jade or Xiu jade. However, if you want to carve such a large piece of jade into a jade seal, the best choice is Duyu."

Wang Guan nodded slightly and felt that it made sense. After all, this piece of jade seal was more than ten centimeters in length and height. It was also delicate, soft, glossy and transparent, so it was definitely the best jade material.

In that era of war and chaos, transportation must have been hindered. Zhang Xianzhong was also busy defending the enemy and fighting, and he probably didn't have the heart to abandon the near and seek the distant, so he sent people to distant places to buy Hetian jade. Therefore, he had to settle for the next best thing and get Dushan jade.

Made a jade seal.

Of course, although this statement has some truth, it can only be used as a reference and is not the main basis for identifying the authenticity of the jade seal.

At the same time, Yu Feibai smiled and said: "Also, when I visited the Jade Seal in the Forbidden City, I once listened to the commentator describing the changes of the Jade Seal in the past dynasties. Among them, there is such a detail, but I still remember it fresh."

"What details?" Wang Guan asked quickly, very excited. Because when appraising an object, it is often the small and inconspicuous details that play a decisive role.

"Jade seals, before the Tang Dynasty, had dragon buttons, tiger buttons, unicorn buttons, etc. But in the Tang Dynasty, Li Yuan's grandfather was named Li Hu. He was a minister in the Northern Zhou Dynasty and was named Tang Guogong. This is the origin of the country's title in the Tang Dynasty.

." Yu Feibai talked eloquently: "After that, Li Yuan established the Tang Dynasty. In order to avoid the taboo of his grandfather's name, he no longer used the jade seal with tiger buttons."

"So, after the Tang Dynasty, the shape of jade seals was basically standardized. Dragon buttons were all used, such as Panlong button, Crouching dragon button, Crossing dragon button, Dual dragon button, etc. We have never seen tiger buttons again.

form."

Yu Feibai smiled brightly and said: "By coincidence, I checked the information in the past two days and found that historical records record that Zhang Xianzhong was tall and yellow-faced, and was as brave as a tiger in battle, so he was nicknamed the Yellow Tiger and was known as the Eight Kings. After all, Zhang Xianzhong was a grass-head

He was born as a king and liked the nickname Huang Hu, so he often referred to himself as a fierce tiger. Therefore, I am afraid that only he can make and use the tiger button-style jade seal."

"Pah, pah, pah..."

Wang Guan couldn't help but clapped softly and extended his thumb. Putting aside other factors, simply listening to Yu Feibai's analysis can make people 80% sure that this thing is the jade seal used by Zhang Xianzhong to found the country.

"It's funny, it's funny."

At this time, Yu Feibai became modest and said with a smile: "If you are worried, you can ask an expert to identify it. Or, simply take the ink pad under the jade seal for testing. Presumably, these ink pads are hundreds of years old."

"We'll talk about this later. Now I want to see what kind of treasure it is, also hidden in the box. It's obviously as important as the jade seal." Wang Guan said with interest, casually taking the long object in the box.
