The princess traveled through time for a year to help the prince build his kingdom and then left

In the tree hole.

Zuo Qingyun and Qin Rubing have been wandering in this mysterious place for several days.

Every step is full of unknowns, as if being in an endless maze.

When they are thirsty, they drink the clear and sweet mountain spring water; when they are hungry, they rely on the rich resources in the mountains - either picking delicious and juicy wild fruits to fill their stomachs, or using their agility to catch fish and pheasants and cook them into delicious dishes.

When night fell, the two of them found a flat place, used the earth as their bed and the sky as their blanket, and fell asleep peacefully.

Despite all the hardships and efforts, the legendary place where countless precious treasures are hidden has never appeared.

The fire of hope in their hearts sometimes burned brightly, and sometimes almost went out, but no matter what, they never gave up the search.

Three days passed.

"Take another look at the treasure map?" Zuo Qingyun suggested.

"it is good."

Qin Rubing carefully took out the mysterious and ancient treasure map from her arms.

The two sat together, spread the treasure map in front of them, and looked at it carefully, trying to find a clue from the yellowed map.

However, after a long period of research, they found that apart from clearly marking the location of the huge old tree, there was no mention of the topography inside the cave.

The treasure map was like an alluring puzzle that only gave half the answer, leaving them in deep confusion.

Qin Rubing frowned and gently stroked the edge of the treasure map with her fingers, as if she wanted to feel the hidden information from it.

She murmured to herself, "Is this all? Why is there no description of the inside of the cave?"

Zuo Qingyun on the side encouraged: "Maybe we need to think from a different angle, or look for other relevant clues to solve this mystery."

"By the way, I have another ancient book." Qin Rubing took out the ancient book again.

"The book contains nothing but the origin of the treasure and how to crack the mechanism of the tree hole door."

Qin Rubing said this and handed the book to Zuo Qingyun.

Zuo Qingyun stretched out his hands, took the mysterious book, and said softly, "Let me see."

He gently turned the pages of the book, as if he was uncovering a long-covered veil, and began to read every line of text, word by word, with a focused and serious look.

However, as he continued to turn the pages until the last page, he still failed to find any more text information of practical value.

Just as Zuo Qingyun was about to put down the book, a unique pattern on the back cover caught his eye.

Its lines are simple yet full of mysterious charm, as if it hides some unknown secrets.

Zuo Qingyun took a closer look and suddenly had an idea. "Rubing, look, what does this pattern look like?"

Qin Rubing leaned over to take a look and found it a little strange. "Why didn't I notice this pattern before? It looks familiar."

She looked at the pattern and then at her surroundings.

"I see. This pattern depicts a certain place in this tree hole."

Zuo Qingyun looked around, feeling somewhat worried. "This cave is so big, where could the pattern be drawn on?"

"Yes, this pattern only shows a part, and there is no landmark here?" Qin Rubing said to himself.

"Marker?" Zuo Qingyun looked at her puzzledly.

"It's something with characteristics. For example, a waterfall, a stream, a big tree, a rock..."

Qin Rubing observed her surroundings while listing the distinctive things she could see.

"Look at that big rock. Doesn't its shape look like the rock in the book?"

Qin Rubing looked in the direction where Zuo Qingyun pointed. On the hillside not far away there was a large rock several people tall, shaped like a rooster singing loudly.

She lowered her head to look at the book again, and sure enough, there was also such a big stone in the pattern on the back cover.

The two did not dare to delay for even a second and hurried towards the hillside.

They climbed up the hillside breathlessly, approached the big rock cautiously, and felt the mysterious aura it exuded.

Carefully comparing the patterns in the book, they patiently groped their way around the huge stone.

The surface of this big stone was surprisingly smooth, as if it had been carefully polished, without any rough texture.

After a long search, Qin Rubing finally found an inconspicuous bulge.

This bump is so tiny that it is almost impossible to detect without careful observation.

According to the method he had learned before to open the tree hole door, Zuo Qingyun cut his finger without hesitation, and dripped bright red blood onto the bulge.

In an instant, a mysterious force seemed to be activated. With a loud "boom", the originally closed stone door slowly opened, revealing a dark and deep passage before the eyes.

Zuo Qingyun and Qin Rubing were filled with excitement. They looked at each other and walked into the stone gate side by side.

When they stepped in, they were surprised to find that it was indeed a huge warehouse as the legend said!

All around me were piles of gold, silver and jewels of all kinds, sparkling with dazzling light.

There are so many treasures that it is dizzying to look at. It is simply an inexhaustible treasure trove.

The tenth day of October, in the imperial capital, at Prince Yan’s Palace.

Chu Tiancheng had just seen off the last batch of ministers who came to report matters, and turned to walk towards his study.

During this period, Crown Prince Chu Tianxing was punished to reflect on his mistakes behind closed doors, and Chu Tiancheng assisted the Eastern Emperor in handling state affairs.

The wind direction in the court changed quietly, and many ministers intended to get closer to Chu Tiancheng.

Chu Tiancheng returned to the study and saw a letter delivered by carrier pigeon on the desk, which was marked as coming from Linshan County.

An inexplicable sense of nervousness surged in his heart. He walked quickly forward, picked up the envelope impatiently and opened it quickly.

He eagerly scanned the words on the letter paper. Suddenly, his eyes became shocked and he muttered to himself:

"What? The princess actually entered that mysterious forest and hasn't come out for three days?"

This news was like a thunderclap in his heart, and he instantly fell into deep worry.

He knew very well that the dense forest was full of unknown dangers and variables, and it was really worrying that the princess had rashly intruded into it.

Chu Tiancheng suddenly jumped up from his seat and shouted outside: "Yan Yi!"

Before he finished speaking, a black shadow flashed into the house like a ghost.

This person was Yan Yi, who had a strong figure and moved as swiftly as the wind.

"You must make arrangements immediately. I have decided to go to Linshan County immediately! There must not be any delay!"

Chu Tiancheng was extremely anxious, and his tone was firm and unquestionable.

"Yes, sir!" Yan Yi responded without hesitation, turned around and left at lightning speed, and began to make intensive preparations for the trip.

Chu Tiancheng held the information tightly in his hand and read it over and over again. Every time he read it, his worries grew heavier.

"Qin Rubing, ah Qin Rubing, you must not make any mistakes, otherwise I..."

He muttered to himself, his eyes revealing endless worry and concern.

There seemed to be thousands of words hidden in those deep eyes, but at this moment they could only turn into silent prayers and silent concerns.

After Yan Yi left, Chu Tiancheng paced back and forth in the room, feeling extremely anxious. He kept thinking about the dangers Qin Rubing might encounter and how to get to her as soon as possible.

At this time, a guard came hurriedly and handed over the latest intelligence. Chu Tiancheng took it hurriedly, unfolded it and looked at it, his face became more solemn.

It turned out that the mountain road near Linshan County had recently encountered a mudslide, which blocked the road and made it difficult to pass. But this did not stop Chu Tiancheng's determination to move forward. He immediately summoned his confidants to discuss countermeasures.

Finally, they decided to take a detour. Although the journey was long, they could reach Linshan County faster. Chu Tiancheng led a team of elite soldiers and set out on the journey without stopping.

Prince's Mansion.

As soon as Chu Tiancheng stepped out of the imperial capital, Chu Tianxing quickly learned the news.

Chu Tianxing has been keeping a low profile recently and has not left his house, but he has never relaxed his surveillance of Chu Tiancheng.

He had planned it in advance and secretly sent his trusted people to keep a close eye on Chu Tiancheng's whereabouts.

At this moment, these specially selected trackers quietly followed Chu Tiancheng out of the imperial capital.

Everything is under Chu Tianxing's control. When the time is right, he is ready to give Chu Tiancheng an unexpected blow.
