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

The man in black stepped forward with a sword in hand, trying to snatch the ancient book from Qin Rubing's hand.

Qin Rubing smiled calmly and said to "Xiao Yu" with her mind: "I want to enter the space."

In an instant, Qin Rubing disappeared from the dilapidated house.

The black-clothed man's sword had already thrust out, but he failed to stop and fell face first into the dirt.

He got up from the ground and looked around, but couldn't find any trace of Qin Rubing.

It's haunted!

The man in black felt a chill on his back and fled the scene in panic.

After the man in black left, Qin Rubing came out of the space and returned to her room with the book.

She studied the treasure map carefully and summoned "Xiaoyu".

With the help of "Xiao Yu", Qin Rubing quickly found the right path to the treasure.

The next morning, the sun shone through the gaps in the dense leaves, casting mottled shadows. Zuo Qingyun and Qin Rubing led a team of more than a dozen people into the mysterious and deep forest.

These people are agile and have firm eyes, and are obviously veterans of many battles.

However, their every move has fallen into the eyes of spies sent by various forces in the underworld.

These spies lurked in the dark like ghosts, closely watching the movements of the treasure hunting team.

Not long after Zuo Qingyun and his companions entered the dense forest, several more groups of people followed them in from behind.

Some are members of a mysterious organization dressed in black, moving quickly and silently; some are a group of martial arts knights with long swords on their backs, each of them is heroic; and some are people from the martial arts world dressed in different styles, each with different purposes.

This dense forest seems to have turned into a huge stage, with various characters appearing one after another, and a thrilling treasure hunt begins.

Qin Rubing carefully put away the treasure map, her eyes gleaming with anticipation.

This time, she decided to take another risk and quietly activated the navigation function that had been hidden for a long time.

Following the navigation instructions, Qin Rubing, Zuo Qingyun and his party stepped into the dense forest.

They walked along the winding path, and the fallen leaves rustled under their feet.

Qin Rubing walked at the front of the team. She walked lightly and observed the surrounding environment with sharp eyes.

Occasionally, she would stop and check the treasure map and navigation information in her hand to make sure everyone was on the right track.

Under her guidance, they passed through deep woods and crossed fast streams.

Sometimes, they need to climb steep slopes; sometimes, they have to carefully pass through thorny areas.

But no matter what difficulties he encountered, Qin Rubing always remained calm and decisive, leading everyone step by step towards the goal.

The group followed Qin Rubing for most of the day until she finally stopped.

Everyone was surprised to find that the target Qin Rubing pointed to was actually a century-old tree.

Qin Rubing walked around the tree several times but couldn't see any clues.

She didn't think at all and just followed the navigation.

It can’t be wrong!

Qin Rubing knocked on the tree trunk again and again, but there was no response. Where was the mechanism?

Suddenly, she remembered the ancient book and quickly took it out to read it.

After flipping through a few pages, she found a pattern of a big tree, which was exactly the same as the big tree in front of her.

According to the book, we need to find a mechanism to open the secret room.

Where is it?
