She married a dying prince and she won three babies.

"Ah."

"Why is there another box?" Yu Yuanzheng 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.

This box is obviously made of jade, crystal clear and without any flaws. The quality of the jade is absolutely top quality.

Yu Yuanzheng 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, making her pull her hand back in shock.

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

Yu Yuanzheng 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 emits a faint cold light, full of mystery.

Yu Yuanzheng couldn't help but move closer. Although she had just retracted her hand because of the cold, 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 carefully at the surface of the jade box.

The lid of the jade box is carved with intricate patterns, which look like some ancient symbols or the veins of mountains and rivers.

He gently stroked the lines through the fabric 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 Yuanzheng blinked. "A mechanism? Do I have to untie it before I can open it?"

Shangguan Ziqi nodded, his gaze still fixed on the jade box. He gently pressed the edge of the lid, and sure enough, he felt a slight dent somewhere. With a slight click, the lid of the jade box slowly opened a crack.

"It's open!" Yu Yuanzheng moved closer to take a 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 in a pillowcase and gently opened the lid of the box completely. No poisonous smoke or hidden weapons emerged from the box, only a neatly folded piece of parchment lying quietly inside.

"Is this... a treasure map?" Yu Yuanzheng widened her eyes. The emperor had really guessed it right.

Just reach out and take it.

Shangguan Ziqi stopped her again, "Wait, it's been in the jade box for too long, so it's also very cold."

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 have turned a little yellow, obviously having gone through a long time.

Shangguan Ziqi unfolded the parchment and spread it flat on the table, but saw nothing. Just a piece of parchment.

The two looked at each other.

"How could this be? Is this a wordless book?" Yu Yuanzheng blinked and looked again, but there was still nothing.

"Something that is so solemnly placed in a thousand-year-old cold jade box must be a treasure." Shangguan Ziqi was very sure.

"But there's nothing on it."

"It must have been 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 Yuanzheng 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 water, 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.

Couldn't this parchment be 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.

This further confirmed his guess.

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

At this time, the parchment was no longer so cold that Shangguan Ziqi could pick it up directly with his hands.

Then support yourself with your hands and warm yourself close to the candle flame.

As the temperature of the parchment surface rose, pictures and texts 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 Yuanzheng exclaimed.

A complex map was drawn on it.

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

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

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

Shangguan Ziqi nodded and whispered the words: "The source of the dragon vein, the secret of heaven and earth."

"The source of the dragon vein?" Yu Yuanzheng was stunned for a moment. "What do you mean?"

Shangguan Ziqi's gaze grew profound, and he slowly spoke, "Legend has it that dragon veins are where the spiritual energy of heaven and earth converges. Those who control them can control the destiny of the world.

This treasure map might point to more than just a treasure, perhaps it's a force capable of changing the landscape."

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

Yu Yuanzheng's heart trembled when he heard this, and he couldn't help swallowing, "Then... did we discover something incredible?"

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

Shangguan Ziqi didn't continue roasting, knowing that doing so would allow him to see it.

He folded the parchment again, placed it back in the jade box, and then carefully closed the jade box. The cold air from 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 Yuanzheng patted his chest.

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

It opens easily.

But the contents inside made both of them exclaim in surprise: "Jade Seal!?"

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

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

A lifelike coiled dragon is perched above the jade seal, with its scales clearly visible and its whiskers flying. Two blood-red gems are inlaid in the dragon's eyes, which seem to be glowing with an enchanting light upon closer inspection.

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

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

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

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

The mountains rise and fall, and the rivers flow, 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 shrouding 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.

"My dear, isn't this the imperial seal of the Great Wei? If the Emperor knew we had it, wouldn't he think we were planning a rebellion?"
