She married a dying prince and she won three babies.

After walking a few steps, Elder Du discovered another mechanism.

There were several protruding stones on the stone wall. After carefully observing them, he said, "These stones are the triggers for the hidden weapons. Everyone, don't touch them."

Under his guidance, everyone avoided several deadly traps and finally arrived at the second stone gate.

This stone gate is more majestic than the first one. There is a coiled stone dragon engraved on the gate, and two gems are inlaid in the dragon's eyes. Under the illumination of the fire, it reflects light, as if watching the intruder.

Elder Du approached the stone gate and carefully studied the patterns on the dragon's body.

After a moment, he said, "This door is also a mechanism, and it's related to the dragon on the stone door. Everyone, wait a moment, I'll study it."

It was more than a quarter of an hour later that he finally noticed something.

Elder Du pointed to several scales on the dragon's body and said, "These scales can be pressed, but the order must be correct. Otherwise, it may trigger more dangerous mechanisms."

Elder Du pondered for a moment, and then pressed down several scales one by one according to the records in ancient books.

As the last scale was pressed down, the giant dragon on the stone gate seemed to come alive, the gem in the dragon's eye suddenly lit up, and the stone gate slowly moved from the middle to both sides.

Before everyone had time to be happy, there was a sudden sound of machinery in the passage, and countless arrows shot out from the walls on both sides!

"Be careful!" Elder Du shouted and quickly squatted down.

Everyone also dodged, and fortunately they reacted in time and no one was injured.

Shangguan Ziqi has always been protecting Yu Yuanzheng.

"Madam, follow me closely and step on the footprints I left behind." Shangguan Ziqi whispered.

"Ah."

After the rain of arrows, Elder Du stood up and dusted himself off: "It seems that it is not easy to find the treasure.

I guess the royal family of the previous dynasty was also on guard, and not everyone could come in.

Although I have solved these mechanisms, there are still many tests.

Everyone needs to be more careful on the road ahead."

The third stone door appeared before everyone. This door was even more mysterious than the previous two. There were no patterns on the door, only a huge "dragon" character engraved in the center.

The word "dragon" is written to look like a vivid dragon.

There is a small protrusion in the middle.

Elder Du walked closer to take a closer look.

The small protrusion is like a small bowl, with a small hole at the bottom. There are a few small words on the front of the bowl: "Royal Blood Guide."

Everyone came over to look.

Everyone saw those four small words.

The literal meaning of these four words is very simple.

Elder Du stared at the four words with a frown.

He muttered to himself, "Royal blood? Does it require the blood of a royal family member to open it?"

To get the treasure, one must be a member of the royal family.

"I didn't expect that the previous dynasty hid the treasure so tightly that we can't get it even if it's right in front of us." Elder Du sighed helplessly.

The prince and Shangguan Ziqi looked at the words and exchanged glances.

Yu Yuanzheng also saw the eye contact between father and son.

Yes, aren't they descendants of the previous dynasty in terms of bloodline? But it's been so many generations, I don't know if it still matters.

"Your Highness." Shangguan Ziqi called softly.

The prince turned around in confusion.

The Crown Prince had never read the letter left by the ancestor of the Rong Palace, so he did not know that the third generation Rong Palace Princess was the granddaughter of the last princess of the previous dynasty.

"Your Highness, let me try." Shangguan Ziqi said again.

The prince was shocked. Anyone could understand the meaning of those four words.

"Ziqi, it's talking about royal blood, but my blood should be more effective." The prince thought Shangguan Ziqi just wanted to try it with his own blood.

Although he wasn't from the previous dynasty's royal family, he was the current crown prince. Some mechanisms were quite mysterious, and perhaps they simply referred to members of the royal family in general, not necessarily members of the previous dynasty's royal family.

The prince did not give anyone a chance to stop him. He simply rubbed his index finger lightly on the sword, and a thin bloody wound oozed out.

The prince reached out to the small bowl and squeezed a few drops of blood into it.

Everyone stared at the few drops of blood.

Blood slowly seeped in from the small hole.

Everyone waited for a quarter of an hour, but there was no response.

"Your Highness, let me try too." Shangguan Ziqi also picked up the sword and lightly drew a line on his fingertips.

Five drops of blood were dripped into the small bowl.

Everyone stared at the drops of blood again.

It seeped in slowly just like before.

Miraculously, everyone heard the sound of the mechanism.

Then the stone gate really began to move to both sides.

But it only moved a palm's width before stopping.

Could it be that Prince Rong’s Mansion is related to the royal family of the previous dynasty?

Elder Du looked at Shangguan Ziqi with bright eyes.

The prince also looked at Shangguan Ziqi in disbelief.

"Uncle Rong?" The prince turned and looked at the prince again.

A look of confusion.

"Crown Prince, my Rong Palace has some connections with the royal family of the previous dynasty. I will tell you after returning to Beijing." The prince did not want to talk about this in front of outsiders.

The prince looked away. Now was not the time to think about this.

"Your Highness, it's so narrow that no one can get in. Only a rabbit can pass through." Elder Du said regretfully.

The prince said nothing, walked forward, cut his finger with the sword, and dripped a few drops of blood into it.

When the blood seeped in, a mechanical sound was heard again.

The stone door opened a little more, but only half a foot, enough for a child to go in.

Everyone looked at each other.

What should I do?

"Father, why don't we let Dabao and the others try too?" Yu Yuanzheng's voice suddenly rang out.

The prince originally wanted to see his precious daughter, but she was so far away that it would take at least more than a month to go back and forth.

As a result, Yu Yuanzheng spoke up.

Upon hearing this, the Crown Prince laughed and said, "Haha, yes, there are still three children from Prince Rong's Mansion who haven't tried it yet. Well, let's stop here today. The treasure is right before our eyes, so there's no need to rush. We'll talk about it tomorrow when the three treasures from Prince Rong's Mansion come."

Everyone had to withdraw.

The next day, Yu Yuanzheng and his wife returned to the city and brought their three children with them.

When the three children arrived at the valley, they looked curious.

"Mom, are you taking us here to hunt?" Dabao looked around curiously.

But why did so many people come to hunt?

When we first entered the valley, we saw many tents, obviously belonging to soldiers, all wearing armor.

They remember clearly that when Dad returned to the city after winning the battle, he was wearing armor.

My grandmother said that those who wear armor are heroes of the Wei Dynasty.

Later they learned that they were soldiers defending their country.

And their grandfather also told them that when he and his brother grew up, they would have to shoulder the responsibility of defending the country.

"Dabao, mom is taking you to hunt for treasure." Yu Yuanzheng whispered in Dabao's ear.

"Really?" Dabao became interested immediately after hearing it.

Bao, everyone likes it.

Even though he is only four years old, he is very sensitive to treasures.

Because he asked his mother why the three brothers and sisters were called Dabao, Erbao and Sanbao.

My mother said that they are the most precious treasures in their parents' hearts.

That means treasure is the best thing in the world.

When the person arrived, the prince ordered to go and investigate again.

The prince took the eldest treasure, Prince Jing took the second treasure, and the crown prince took the third treasure himself.

The three kids weren't afraid at all; they were so brave. I don't know who they took that from.

The first time Yu Yuanzheng was led by Shangguan Ziqi, she couldn't help but want to close her eyes.

The three children were actually very excited as they watched the distance between them and the ground getting higher and higher as they climbed onto the adults.

They are probably used to flying high because of their father and grandfather.

Yesterday's group came to the third stone gate again.

It's still only half a foot open.

But after a night, the air had circulated almost completely.

Yu Yuanzheng didn't feel depressed.

"Children, the treasure we are looking for is inside this stone door.

We need a little bit of your blood to open this door.

Mother will prick a small hole in your finger, but it won’t hurt too much, just like a mosquito bite.”

Yu Yuanzheng explained everything clearly to the children before taking action.
