Xiao Ruyu turned his head away guiltily and leaned on his shoulder without saying a word.

Doctor Yang stood up and saluted.

"Then I will take the little princess away first."

Queen Duan nodded and watched the two of them leave.

The National Treasury is an important place in the imperial palace. There are many soldiers guarding outside the gate, and dozens of people patrolling back and forth inside and outside.

As soon as Doctor Yang stepped into the area outside the treasury, he was stopped by someone.

"stop!"

The person who came was the leader of the officers and soldiers. When he saw that the person was Doctor Yang, he saluted.

"Lord Yang, the national treasury is the focus. You are not allowed to approach without a written order."

"This is?"

He noticed the glutinous rice balls in Doctor Yang's arms, took a closer look, and quickly knelt down to pay his respects.

"Meet Princess Fu'an."

Xiao Ruyu shook the token in his hand and spoke in a baby voice.

"My mother asked me and Doctor Yang to come to the treasury to check some things. Here, I will give you the token."

The officers and soldiers took the token respectfully and made way for the three men.

When the door of the treasury was opened, the magnificent scene was jaw-dropping.

Several rare and valuable items were placed on various wooden shelves, including gold, silver, jewelry, pearls, jade, agate, and other rare and precious objects.

In the center of the treasury stood a vermilion sandalwood table, covered with a thin silk cloth, and on it were files laid out—

This is exactly what they are looking for this time!

Doctor Yang stepped forward quickly and spread out the files.

Xiao Ruyu felt overwhelmed when looking at the densely packed words.

[With so many, how can I find out where this medicine cauldron came from? ]

Eleven, who had been silent for a long time, suddenly spoke.

"The records are all written with the year."

“Different objects have different pages.”

After learning this important news, Doctor Yang hurriedly began to search.

Two hours later, Xiao Ruyu collapsed to the ground, with the files scattered all over the floor.

[Where is it? I’ll never be done even if I keep looking for it for days and nights! ]

She scratched her head in annoyance, picked up a file beside her and read it out slowly.

"In the twenty-third year of Xuan State, a neighboring country paid tribute to us with a medicinal cauldron."

She immediately sat up and hurriedly handed it to Doctor Yang.

【Master, is this it? 】

Seeing that the medicine cauldron drawn on it was exactly the same as the Nine Revolutions Cauldron, the two of them felt like they had grasped a life-saving straw.

Doctor Yang hurriedly continued to turn the page, but was dumbfounded.

[What? Only this line of records? ]

Xiao Ruyu flipped through the pages in disbelief, but apart from the record of the year, there was nothing else.

Doctor Yang sighed and explained.

"The twenty-third year of Xuan Country is nearly a hundred years. It is normal that we cannot find the origin since it is so long ago."

Unexpectedly, the clues they had finally found came to an abrupt end, and both of them sat on the ground somewhat disappointed.

Xiao Ruyu was unwilling to give up, and a thought came to his mind.

【Master, I have a solution. 】

She looked at Doctor Yang seriously and expressed her thoughts.

[I will try to see if I can bring the Nine Revolution Cauldron back to the space. Since it is something from Medicine King Valley, it must be able to play a role in it.]

Doctor Yang thought about it and agreed with her idea.

"This Nine Revolutions Cauldron can refine everything in the world. The reason why it is called the Nine Revolutions Cauldron is that the medicine is refined 9981 times in it, and the resulting elixir is comparable to a divine elixir."

“Since the spiritual spring in Medicine King Valley can be brought out to treat diseases, maybe if we bring the Nine Revolution Cauldron back, we can use it to its full potential in the previous life!”

There was no time to lose, and Doctor Yang immediately took her back to where the Nine-Revolution Cauldron was stored.

Xiao Ruyu took a deep breath, concentrated his mind and energy, and gently placed his palm on the Nine Revolutions Cauldron.

She closed her eyes and flashed into the storage space.

Opening his eyes and looking at the Nine Revolutions Cauldron in front of him, Xiao Ruyu couldn't suppress his inner excitement.

She stretched out her hand to mobilize her spiritual power to see if the Nine Revolutions Cauldron still had the same function as in her previous life.

A stream of spiritual power rushed in, and the Nine Revolutions Cauldron emitted a faint purple light, which shot straight into the sky.

After the light faded, Xiao Ruyu realized that he could go one step further into Medicine King Valley.

This Nine Revolutions Cauldron is indeed a spiritual weapon!

Xiao Ruyu couldn't wait to tell Doctor Yang the news, and closed his eyes, trying to get out of the space.

The next second, she opened her eyes again, and before her eyes was still the green hills and clear waters of the back mountain of Yaowang Valley.

What's going on?

Xiao Ruyu was a little panicked. She tried a few more times, but found that she couldn't get out no matter what.

Now she was completely anxious, and looked at the storage ring on her hand, which was still emitting a faint light.

But he seemed to be trapped between this four directions of heaven and earth, completely isolated from the outside world.

"What is going on? Why can't I get out?"

Xiao Ruyu murmured, his eyes falling on the Nine Revolutions Cauldron in front of him.

She circled the Nine Revolutions Cauldron several times, looking at the faint purple light on it thoughtfully.

Is it because of the spiritual power I injected into it?

Xiao Ruyu tried to mobilize his spiritual power again and attack it. After the Nine Revolutions Cauldron absorbed the spiritual power, the purple light on its body became stronger.

But her weak spiritual power was not enough to satisfy the Nine Revolutions Cauldron in front of her.

Just when Xiao Ruyu was at a loss, the Nine Revolutions Cauldron suddenly changed.

The spiritual power that had just been absorbed was now "spitted out" again.

Looking closely, the spiritual power was several times stronger than before.

An idea suddenly flashed through Xiao Ruyu's mind.

She quickly sat down in meditation, activated her Dantian, and absorbed the rich spiritual energy.

After several rounds, Xiao Ruyu exhaled a breath of turbid Dan Qi.

She didn't expect that this Nine Revolutions Cauldron could actually improve her cultivation.

If we continue like this, as long as we cultivate our spiritual power to a certain concentration, we will definitely be able to open the barrier and get out.

…

No one knew how much time had passed, but Xiao Ruyu could no longer distinguish between day and night.

It is estimated that over the past few months, the spiritual energy in his body has become increasingly strong.

And her cultivation is also growing day by day.

Finally one day, Xiao Ruyu suddenly opened his eyes, and a powerful spiritual power quickly condensed in his palms.

He flipped his hand and hit the Nine Revolutions Cauldron, and the purple light on the cauldron finally turned into dark purple.

As the barrier was broken, Xiao Ruyu moved directly out of the space.

The first thing she saw was Eleven standing in front of her.

"eleven!"

Xiao Ruyu threw herself into his arms, her voice somewhat tearful.

[I thought I would never come back. How long has it been?]

Eleven was a little confused, and seeing her tears as big as beans falling, he quickly reached out to wipe them away.

Xiao Ruyu asked while sobbing.

[What year and month is it now? Have my parents come to see me? ]

【What about you? You don't look surprised at all. 】

[Have you already forgotten this princess? ]

"Princess, what happened? It's only been half an hour."

He scratched his head in confusion, but seeing that Xiao Ruyu was already crying, he quickly began to explain.

Wait, half an hour?

Xiao Ruyu's crying suddenly stopped. She raised her head, with tears still on her long eyelashes.

[Only half an hour has passed? ]
