She married a dying prince and she won three babies.

"Your Highness, I have something to report." Shangguan Ziqi put Yu Yuanzheng down and said excitedly.

"Oh? Have you two also found any clues?" The prince knew from the expressions of the two that they must have discovered something.

“Yes, there are dozens of cypress trees on the hillside not far from here.

Madame found them arranged in a very regular pattern.

We have drawn the arrangement of the trees for your review, Your Highness."

Shangguan Ziqi took out the piece of paper from his bosom and handed it to the prince, treating it as if it were a priceless treasure.

Prince Jing and Prince Rong both came over to watch. Rong Luo was also curious and stretched his head over.

"Earth!?" several people chanted at the same time.

"Your Highness, my two princes, I was just about to say that if we add another horizontal line from that position on the cliff, it will form the character '天'." Rong Luo said, pointing to the cliff not far away.

Then he repeated his findings and guesses.

After hearing this, several people looked carefully in the direction he pointed.

We all practice martial arts and have good eyesight, and it is really as he said.

Only Yu Yuanzheng couldn't see so carefully.

The prince pondered for a moment, his eyes moving back and forth between the cliff and the word "Earth" in his hand, excitement flashing in his eyes.

He turned to look at Rong Luo and asked, "Young Master Rong, how do you think we should fill in that horizontal line?"

Rong Luo replied respectfully, "Your Highness, from what I have seen, that horizontal line may not be a physical line, but may require some kind of mechanism to trigger it.

The cracks in the cliffs and the water flow have formed the Chinese character "人" (person) and a horizontal line. If we can find the mechanism at the top of the "人" character, perhaps we can complete the "天" character and open the entrance to the treasure."

The Crown Prince nodded and turned his gaze to Prince Jing and Prince Rong: "My two uncles, what do you think?"

Prince Jing stroked the small strand of beard under his chin, thought for a moment, and then said, "Young Master Rong is right. We might as well give it a try."

"That's right. But the cliffs are steep and the traps are hard to find, so we need to be careful." Prince Rong also agreed.

"In that case, let's split up. Young Master Rong, you're proficient in Qimen Dunjia, so you'll be in charge of finding the mechanism. Shangguan Ziqi, you're skilled in Qinggong, so take a few people with you and go up with Young Master Rong. Uncle Wang, we'll wait at the foot of the cliff. If they accidentally fall, we'll help them."

Everyone responded in unison and took action.

Shangguan Ziqi, along with Rong Luo and several agile guards, slowly climbed up the cliff.

The cliffs were steep and the rocks slippery, so the men climbed cautiously, fearing a fall. As Rong Luo climbed, he carefully observed the cracks and currents on the cliffs, trying to find clues to the mechanism.

Yu Yuanzheng stood below, looking up at them, feeling both nervous and expectant.

Although she didn't understand the tricks of these mechanisms, her intuition told her that the entrance to the treasure was right in front of her.

Suddenly, Rong Luo stopped moving, his gaze fixed on a crack. He reached out and gently touched the edge of the crack, discovering a slightly raised rock there, slightly different from the rest. He turned back to Shangguan Ziqi and whispered, "Prince, there seems to be something unusual here."

Shangguan Ziqi took a closer look and discovered that the rock was indeed different from the others, as if it had been placed there by humans. He grabbed the protruding rock with one hand and, together with Rong Luo, pushed it. The rock actually sank slowly with a distinct "click".

At this moment, the water flow on the cliff suddenly changed.

The water that originally flowed downwards miraculously flowed upstream and gathered in the middle of the Chinese character "人", forming a water line across the cliff.

The waterline gleamed in the sunlight, like a silver horizontal line, completing the character "人" (man) into a complete character "天" (sky).

"Found it!" Shangguan Ziqi exclaimed excitedly.

The prince and others below also saw this scene and showed surprise.

The prince waved his hand, signaling everyone to be careful.

Rong Luo and Shangguan Ziqi continued to climb and reached the top of the character "天". There was a huge rock with intricate patterns carved on its surface, which seemed to be an ancient mechanism.

They were too far away to see before, but now they were closer and could see clearly.

Rong Luo studied it carefully and found that there was a circular groove in the center of the rock, with eight directions engraved around the groove.

"This is the Bagua mechanism." Rong Luo whispered, "It needs to be turned in the correct order to open the entrance."

Shangguan Ziqi frowned: "But we don't know the correct order."

Rong Luo pondered for a moment, and suddenly his eyes lit up: "'The source of the dragon vein, the secret of heaven and earth', perhaps the clue lies in these eight words. 'Dragon vein' corresponds to the 'Zhen' position in the Eight Trigrams, and 'Heaven and Earth' correspond to the 'Qian' and 'Kun' positions. We might as well try starting from the 'Zhen' position and moving to the 'Qian' and 'Kun' positions in turn."

Shangguan Ziqi nodded in agreement: "Okay, I'll do as you say."

Rong Luo took a deep breath, reached out and pressed his hand against the rock, and slowly turned the mechanism in the "Zhen" position. As the mechanism turned, a low rumbling sound echoed from within the rock. He then turned the "Qian" and "Kun" positions, one after another.

When the last mechanism was turned, the rock suddenly made a loud noise and slowly separated to both sides, revealing a dark cave entrance.

"The entrance is open!" Shangguan Ziqi was extremely excited.

The prince and others below also heard the noise and looked up.

The prince waved his hand again, signaling everyone to prepare to enter.

Rong Luo and Shangguan Ziqi, along with a few guards, entered the cave first and found a narrow passage inside. Both sides of the passage were engraved with ancient murals that seemed to be telling an ancient story.

But several people didn't understand it at first.

There is water outside, but it is relatively dry inside.

It's amazing.

At the end of the passage, a huge stone door can be vaguely seen. There are complex patterns carved on the door, which seems to be another mechanism.

"It seems we still have to unlock the mechanism of this door." Rong Luo said in a low voice.

Shangguan Ziqi smiled and said, "With you here, these mechanisms shouldn't be a problem."

"No, Your Highness, you are too kind. When it comes to mechanisms, I don't know much. I know someone who is more knowledgeable about them. Perhaps we could ask him for help." Rong Luo said modestly.

"Who?"

"Elder Du from the Qishan Sect."

Shangguan Ziqi thought for a moment. He had come this time too, bringing his disciples with him to work with them, but the prince had sent him elsewhere.

"Let's try it first. If it doesn't work, we can ask him for help." Shangguan Ziqi decided to test it out first.

But the two of them studied it for a long time and couldn't figure out anything.

Even the prince and his men came in, but neither of them could figure out what was going on.

"How is it?" The prince saw them groping in front of the stone gate.

"Your Highness, this door is a mechanism." Shangguan Ziqi turned around and saw them coming in, and stopped groping.
