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

Qin Rubing stretched out her slender fingers and gently touched the extremely smooth bark of the tree.

Her movements were extremely gentle, as if she was afraid of disturbing this ancient and mysterious tree.

She keenly captured and felt the subtle touch of every inch of her fingertips touching the bark.

Qin Rubing explored carefully and attentively, not missing any possible abnormalities.

Her eyes were fixed on her hands, revealing a kind of persistence and determination.

Suddenly, she felt a slight strange sensation at her fingertips - it turned out to be a tiny bulge!

This discovery made her happy, and her tense nerves relaxed a little.

However, when she tried to press the small bulge with her fingers, she did not get the expected reaction.

Qin Rubing was not discouraged. She repeated the same action again and again, hoping to find a breakthrough.

Qin Rubing knew that the more ordinary and mundane details seemed, the more likely they were to hide key clues.

She checked the surrounding bark again. The surface was smooth except for this bulge.

While Qin Rubing was trying to find the mechanism, Zuo Qingyun and others carefully surrounded her. Everyone was on high alert.

They are all martial artists, so their ability to perceive their surroundings is naturally far superior to that of ordinary people.

At this moment, they all became alert and keenly sensed something strange - it seemed that there were many figures hiding in the dense jungle not far away, quietly spying on this place.

The aura of these people was looming, as if blending into the surrounding nature, but it was difficult to completely hide the deliberately suppressed hostility and curiosity.

There was a tense and weird atmosphere in the air, which made people feel cold.

Could it be related to fingerprints? This thought suddenly popped up in Qin Rubing's mind.

She started with the index finger of her left hand and tried each finger one by one.

When she gently pressed the small bump with the tip of her right ring finger, she heard a slight "click" coming from inside the tree.

Then, a hole about one person high and half a person wide opened on the trunk of the thick tree that required two people to hug.

"Xiao Yu, activate the illusion technique. Times the speed 2." Qin Rubing quickly gave the order with her mind.

"Okay, master." "Xiao Yu" activated the illusion technique.

Qin Rubing flashed and, like a nimble civet cat, quickly moved sideways and slipped into the seemingly narrow tree hole.

The moment she entered the tree hole, it seemed as if a mysterious force was controlling everything, and the tree hole actually closed up on its own.

It all happened so quickly that Zuo Qingyun, who was standing nearby, didn't even have time to see clearly what was happening.

He opened his eyes wide with a look of astonishment, watching the tree return to its original appearance in the blink of an eye, as if everything that had just happened was just an illusion.

However, the facts were clear: Qin Rubing had indeed disappeared into the tree hole, and the tree hole had closed without a trace.

Zuo Qingyun couldn't help but fall into deep thought, his heart full of doubts and curiosity.

What secrets does this tree hole hide? And why did Qin Rubing choose to crawl into it?

He rushed forward and touched the tree trunk with his hand, but there was no trace.

The others were even more stunned. Qin Rubing had crawled into the big tree right under everyone's noses.
