She married a dying prince and she won three babies.

"Master Rong, is there nothing you can do?" asked the prince.

"Your Highness, I am not familiar with mechanisms. It would be best to ask Elder Du from the Qishan Sect to try. He is quite knowledgeable about mechanisms." Rong Luo replied regretfully.

"In that case, let's ask Elder Du from the Qishan Sect to give it a try."

The few of them took a good look at the section they had come in from. Apart from some murals on the mountain wall, there was nothing else, and they did not encounter any hidden weapons.

Everyone had to leave.

"Uncle Rong, let's mobilize some troops just in case," suggested the prince.

"Yes, that's exactly what I meant."

The prince went straight back to Fengrong City to find General Chen.

The prince ordered all the tents to be moved here.

Now that we have found the entrance, we must guard it.

When Elder Du of the Qishan Sect received the news, he quickly came with his disciples.

The prince also sent people to inform Qunying Villa and Kongshan Sect to come here.

I feel more at ease having them guarding me together.

However, the news spread quickly, and other people in the martial arts world who had not defected to the prince also gathered at the entrance of the valley.

Everyone knew that the prince and others had found the entrance to the treasure.

Everyone is waiting to see if there is a chance to get a piece of the pie.

Some took the initiative to approach the prince to show their goodwill and want to contribute.

Unfortunately, they have all been found, and the prince does not need any more manpower.

There are more than 20,000 border troops in Fengrong City now. Are they still afraid of these people from the underworld?

As soon as Elder Du arrived, he asked to enter the entrance to check.

Elder Du is also a martial arts master. Although he is over sixty years old, he is still in good spirits.

The prince ordered his men to guard the bottom of the cliff and went up with Prince Jing and Shangguan Ziqi and his wife.

Of course, Yu Yuanzheng was brought up by Shangguan Ziqi.

She had never expected her husband to be so capable that he could climb up with a grown woman like her.

This time it is more than ten feet high, several feet higher than the last time on Yuntai Mountain.

Yu Yuanzheng admired him so much that she was completely overwhelmed, and at the same time, she felt extremely proud and safe.

As soon as he entered the passage, Elder Du was attracted by the complex patterns on the stone door.

He looked carefully at the ancient symbols and patterns, his eyes flashing with excitement.

As a master of mechanical engineering, he was very interested in this challenge.

"Elder Du, do you think there is any way to crack the mechanism on this stone door?" the prince stepped forward and asked.

Elder Du stroked his beard and pondered for a moment before saying, "Your Highness, the mechanism on this stone door is indeed complicated, but it is not unsolvable.

These patterns may seem chaotic, but they actually contain the principles of the Five Elements and Eight Trigrams. If you can find the pattern, you can unlock the mechanism."

After he finished speaking, he took out an ancient book from his bosom, turned to one of the pages, and studied it carefully in comparison with the patterns on the stone door.

Everyone held their breath and didn't dare to disturb them.

Half a minute later, a flash of enlightenment flashed in Elder Du's eyes. He pointed to a circular groove on the stone door and said, "This is the core of the mechanism. We need to press the corresponding positions in the order of the five elements."

As he spoke, he reached out and gently pressed on the stone door. As he moved, a low mechanical sound came from inside the stone door, as if something was slowly turning.

With a "click", the stone door slowly opened to both sides, revealing a deep passage.

"Success!" Everyone showed joy.

Elder Du did not let down his guard. He warned, "Your Highness, there may be more traps in this passage. Everyone must be careful."

The prince nodded.

Elder Du took the lead and stepped into the passage.

"Your Highness, Elder Du, please wait a moment." Yu Yuanzheng suddenly called out.

They both stopped at the same time.

"Sister-in-law, is there anything wrong?" the prince asked doubtfully.

"Your Highness, the stone gate has just been opened. It has been closed for a long time. I guess it has been at least two hundred years. It has not been ventilated for such a long time. If someone rushes in like this, they may have difficulty breathing. It would be better to let it ventilate for a while before we go in. Anyway, it has been opened, so there is no rush."

Yu Yuanzheng felt that the air was very stale at this time, and there was also an uncomfortable feeling.

She had no martial arts skills, and she felt the bad air most clearly.

Only then did everyone feel their breathing carefully, and it was indeed different from outside.

"My sister-in-law is right. How long do we need to wait?" The prince felt that what Yu Yuanzheng said made sense and there was no need to put everyone in danger.

"It will take at least an hour." Yu Yuanzheng gave an approximate time.

There is only one opening for ventilation, which is definitely not enough for a short time.

The prince thought about it and nodded.

"Elder Du, for safety's sake, please come back tomorrow. It's already late and it's almost dark outside." The prince made up his mind not to continue.

In fact, the main reason was that Prince Rong had not yet arrived with his army. If the underworld people rushed over, it would be difficult for them to deal with such a small number of people.

"Your Highness the Crown Prince is right." Elder Du also thought of those people from the martial arts world who gathered at the entrance of the valley.

That night, Shangguan Ziqi personally led his men to guard the cliff.

There were actually a few groups of people who wanted to rush in and take a look, but they were all stopped by the secret guards.

The night passed with occasional screams.

At daybreak, the prince and General Chen came to the valley with 15,000 soldiers.

They had marched all night, and this place was about eighty or ninety miles away from Fengrong City.

As soon as they arrived, they camped at the entrance of the valley.

But even so, those people in the martial arts world were not afraid and insisted on waiting to see what would happen.

The prince saw that those people from the martial arts world refused to leave.

He walked straight forward, took out a black ball, lit it, and threw it at those people, but he didn't throw it at them, but left room for them.

A deafening explosion echoed throughout the valley.

Anyone standing close could see the deep pit.

Those people saw that Prince Rong actually took out all the bombs used on the battlefield.

Some of the Jianghu people became frightened and dispersed in groups of three or five, but most of them were reluctant to leave.

But I was far away and didn't dare to get closer.

The lure of treasure is too great.

"Chen Qiming, guard this place well. If anyone tries to break in, kill him without mercy." The prince ordered in a cold voice.

"Yes, Your Highness." General Chen Xiao responded loudly, also to show those people from the martial arts world who refused to leave.

The prince felt much more at ease when he saw the soldiers coming.

Then everyone came to the foot of the cliff again.

They all used their lightness skills to climb up the cliff.

Shangguan Ziqi carried Yu Yuanzheng on his back as he did yesterday and tied her up with a vine.

Climb up the cliff like a nimble monkey.

Entering the corridor, Yu Yuanzheng felt that the air was indeed much better than yesterday.

Everyone followed Elder Du and continued forward.

The passage is dark but not damp, which shows that the royal family of the previous dynasty chose the location carefully when hiding the treasure.

The murals on both sides looked particularly strange under the light of torches.

Elder Du walked in front, holding a long sword in his hand, knocking on the ground and stone walls from time to time to test whether there were any hidden mechanisms.

Sure enough, not long after they'd walked, Elder Du suddenly stopped and raised his hand to signal everyone to stop. He pointed to a stone slab ahead and said, "There's a trap under this stone slab. Everyone, go around it."

Everyone carefully moved around the stone slabs and continued forward.
