"Um."

"Why is there another box?" Yu Yuzheng was really impressed.

There are boxes inside boxes. Are they playing the gift-opening game?

Shangguan Ziqi took out a smaller box and saw another box underneath.

It's obvious that this box is made of jade. It's crystal clear and without any flaws. The quality of the jade is absolutely top quality.

Yu Zheng reached out to take it.

"Yeah, it's so cold."

When her fingers touched the box, the biting cold air immediately spread to her hand, and she retracted her hand in shock.

"Let me take it. It's made of thousand-year-old cold jade. You need to hold it with a cloth, otherwise your hands will get frostbitten." Shangguan Ziqi recognized the material of the jade box.

Yu Zheng directly took the pillowcase and handed it to him.

Shangguan Ziqi took the pillowcase and carefully wrapped the jade box before taking it out of the box.

The jade box glows with a faint cold light, full of mystery.

Yu Zheng couldn't help but move closer. Although she had just retracted her hand because of the cold, her curiosity made her unable to look away.

"This box doesn't look simple. I wonder what's inside?" she asked in a low voice, with a hint of anticipation and excitement in her tone.

Shangguan Ziqi did not answer immediately, but looked at the surface of the jade box carefully.

The lid of the jade box was engraved with intricate patterns, like some ancient symbols or the veins of mountains and rivers. Through the cloth, he gently stroked the patterns and felt a faint vibration, as if something inside the jade box was responding to his touch.

"This box... seems to have a mechanism." He frowned and said in a low voice.

Yu Zheng blinked. "Mechanism? Do I have to untie it before I can open it?"

Shangguan Ziqi nodded, his eyes still on the jade box. He tried to gently press the edge of the box lid, and suddenly felt a slight sinking somewhere. With a slight "click", the lid of the jade box slowly opened a gap.

"It's open!" Yu Zheng moved closer to take a closer look excitedly.

Shangguan Ziqi raised his hand to stop her, "Don't be impatient, be careful of traps."

As he spoke, he wrapped his fingers with the pillowcase and gently opened the lid of the box. There was no poisonous smoke or hidden weapons coming out of the box, only a neatly folded parchment lying quietly inside.

"Is this... a treasure map?" Yu Yuzheng's eyes widened. The emperor had really guessed it right.

Just reach out and take it.

Shangguan Ziqi stopped her again, "Wait, it has been in the jade box for too long, so it will also turn into ice."

As he spoke, he wrapped his fingers with the pillowcase again and then carefully took the parchment out of the jade box.

The parchment is soft, but the edges are a little yellowed, obviously having gone through a long time.

Shangguan Ziqi unfolded the parchment and spread it on the table, but he saw nothing. It was just a piece of parchment.

The two looked at each other.

"How could this be? Is this a book without words?" Yu Yuzheng blinked and looked again, but still there was nothing.

"The things contained in the thousand-year-old jade box must be treasures," Shangguan Ziqi said with certainty.

“But there’s nothing on it.”

"It should be written with some special ink, and it may need to be processed before it can be seen." Shangguan Ziqi guessed.

In order to maintain secrecy, they also used this method in the military.

"Oh." Yu Zheng also remembered some plots she had seen in movies and TV shows, which seemed to be true.

It is said that if you write with rice soup, nothing will be visible after it dries. But the person reading the letter only needs to spray iodine on the paper and the words will appear.

Isn't this parchment the same?

But there was no iodine in that era, so what should we do?

"Light a candle." Shangguan Ziqi said.

Then he turned the parchment over again, and there was nothing on the back either.

Further confirmed his guess.

Yu Yuzheng didn't understand what was going on, but she went ahead and lit a lamp anyway.

At this time, the parchment is not so cold anymore, and the Shangguanziqi player can pick it up directly.

Then he supported himself with his hands and warmed himself close to the candle flame.

As the temperature of the parchment surface increased, images and text suddenly appeared.

But the candle flame was only a little bit and could not heat the entire parchment.

Once you leave the fire, the pictures and text disappear again, but you can still see them roughly.

"So magical." Yu Zheng exclaimed.

A complex map is drawn on it.

Mountains, rivers, and cities are all marked in detail, and in the center of the map, there is a striking star mark with a line of small words next to it.

"Is this...ancient seal script?" Yu Zheng frowned, not recognizing it.

Although she had seen some ancient artifacts, she was not familiar with this ancient writing.

Shangguan Ziqi nodded and read the words in a low voice: "The source of the dragon vein, the secret of heaven and earth."

"Dragon Vein Source?" Yu Zheng was stunned for a moment, "What do you mean?"

Shangguan Ziqi's eyes became deep, and he said slowly: "Legend has it that dragon veins are the gathering place of the spiritual energy of heaven and earth. If you master the dragon veins, you can control the destiny of the world.

This treasure map may point to more than just a treasure, it may be a force that can change the situation."

Dragon veins are of great concern to the royal family of any dynasty.

Yu Zheng was shocked when she heard this and couldn't help swallowing her saliva, "Then... did we discover something incredible?"

"Don't think too much, it's all man-made. What I just said is just a legend. Just listen to it."

Shangguan Ziqi did not continue roasting, knowing that doing so would be enough to allow him to see it.

He folded the parchment again and put it back into the jade box, then carefully closed the jade box. The cold air of the jade box spread again.

There is also a small square iron box that I haven’t looked at yet.

There is a small lock hanging on the lock buckle.

Shangguan Ziqi picked up the golden key that had just flown out and inserted it into the keyhole.

With a twist, it opened.

Yu Zheng patted his chest.

Fortunately, it wasn't a combination lock, otherwise she didn't know how many times she would have to try.

It opened easily.

But the thing inside made them both exclaim in surprise: "Imperial Seal!?"

After being shocked, Shangguan Ziqi picked it up and looked at it carefully.

The jade seal is crystal white all over, with a faint green hue, as if condensed moonlight.

The jade is as delicate as fat, warm to the touch, yet faintly cool, like a piece of warm jade deep in a thousand-year-old cold pond.

Above the jade seal sits a lifelike coiled dragon, with its scales clearly visible and its whiskers flying. Its eyes are inlaid with two blood-red gems, which seem to be glowing with an enchanting light if you look closely.

The dragon's body meanders down, with its claws tightly clasping the seal's body, as if it will take off into the air at any time.

The seal body is carved with intricate cloud patterns on all four sides, with fine inscriptions faintly visible between the cloud patterns.

Turn the Shangguan chess piece over again and look at the bottom.

What is even more surprising is that at the bottom of the jade seal, on the small space of the seal surface, there is a natural pattern of mountains and rivers.

The mountains are undulating and the rivers are flowing, as if the entire country is condensed in them.

With a slight shake of the hand, the patterns of mountains and rivers seemed to come alive, with clouds and mist lingering between the mountains and waves surging in the rivers.

The most eye-catching thing is of course the four large seal characters on the seal: Destiny is the destiny.

"My dear, isn't this the imperial seal of our Great Wei? If the emperor knew that we had the seal, wouldn't he think we were going to rebel?"
