The princess arrives and the prosperous Tang Dynasty begins

Deep in the vast ocean, a mysterious underwater palace is like a sleeping giant, quietly hidden in it. Lin Xiao and Li Xuan, two curious and courageous explorers, learned about the existence of this underwater palace by chance. Their strong desire for the unknown was instantly ignited, and they decided without hesitation to dive into the unfathomable seabed to explore the secrets hidden in the deep sea.

"Li Xuan, what do you think will be in this underwater palace?" Lin Xiao asked expectantly while checking his diving equipment.

Li Xuan smiled and replied: "No matter what it is, it will definitely open our eyes. Get ready for surprises!"

They put on their special diving gear and resolutely stepped into the cold and dark sea water. As soon as they entered the water, an indescribable sense of oppression surged like a tide, and the surrounding sea water seemed to swallow them up. But they did not retreat at all, relying on firm belief and fearless courage, they continued to swim towards the underwater palace.

Finally, the outline of the underwater palace gradually became clear before their eyes. Its majestic architectural style and exquisite carvings and decorations all spoke of its former glory and magnificence. Lin Xiao and Li Xuan swam carefully into the palace gate in awe.

"Wow, this is so spectacular!" Lin Xiao couldn't help but exclaimed.

"Yes, this is simply an underwater miracle." Li Xuan agreed.

The passage in the palace was narrow and winding, filled with an ancient and mysterious atmosphere. They walked slowly along the passage, the lighting equipment in their hands drew faint rays of light in the darkness. Suddenly, a strange light flashed before Lin Xiao's eyes, and she looked closely and found some strange symbols and patterns engraved on the wall.

"Li Xuan, come and see!" Lin Xiao shouted excitedly.

Li Xuan swam over hurriedly, looking at the symbols and patterns, and couldn't help but frowned: "What does this mean?"

Lin Xiao thought for a moment and said, "I think these may be the clues about time travel that we have been looking for."

"Really? Then we have to study it carefully." Li Xuan said excitedly.

They began to observe these symbols and patterns carefully, trying to decipher more secrets from them.

"Look, this symbol seems to represent time." Lin Xiao said, pointing to a pattern.

"Well, I think it's a bit similar too. What about this one?" Li Xuan pointed to another pattern.

"This... I'm not too sure. It feels like a symbol of some kind of power." Lin Xiao answered hesitantly.

As they continued to go deeper into the palace, more and more clues appeared before them. They found some ancient books that recorded theories and methods about time travel.

"Wow, these books must be very important!" Lin Xiao said in surprise.

Li Xuan carefully picked up a book, turned the pages, looked at the obscure words and pictures on it, and said, "We have to find a way to understand these contents."

They continued to move forward and discovered some strange instruments. These instruments emitted mysterious light and seemed to be closely related to time travel.

"What on earth is this?" Lin Xiao looked at an instrument curiously.

Li Xuan shook his head: "I don't know either, but it's definitely not simple."

In a corner of the palace, they found a tightly closed door with some complex runes engraved on it, emitting a mysterious light.

"There must be a more important secret behind this door." Lin Xiao said affirmatively.

"Then how do we open this door?" Li Xuan looked at the runes on the door and began to worry.

They began to rack their brains to think of ways to crack the rune code. Lin Xiao carefully observed the arrangement and combination of the runes, trying to find the pattern from them. Li Xuan kept trying various possible solutions.

"I think I have some idea." Lin Xiao said suddenly.

"Really? Tell me quickly." Li Xuan asked anxiously.

Lin Xiao pointed at several patterns on the rune and said, "Look, these patterns seem to be in order. Let's try them in this order."

Li Xuan nodded, and gently touched the runes according to the order Lin Xiao said. Sure enough, as he touched it, there was a slight sound on the door, and the runes began to flash.

"There's a reaction!" Lin Xiao shouted excitedly.

They continued to touch the runes in order, and finally, the door slowly opened. Behind the door was a huge room, and inside the room was a huge crystal ball. The crystal ball emitted a soft light, as if it contained endless power.

"This is the key." Lin Xiao said softly.

Li Xuan slowly approached the crystal ball and observed it carefully: "This crystal ball must be extraordinary."

At this moment, the entire underwater palace began to shake violently.

"Oh no, the palace is going to collapse!" Lin Xiao shouted loudly.

"Go!" Li Xuan shouted.

A strong current rushed in from all directions, knocking them all over the place. They tried to keep their balance in the chaos and swam towards the exit.

"Crystal ball, don't forget the crystal ball!" Lin Xiao shouted.

Li Xuan quickly turned around, swam towards the crystal ball, and hugged it tightly.

"Go!" Li Xuan shouted.

With their efforts, they finally managed to swim out of the palace before it completely collapsed.

When they surfaced, the sun shone on them, making them feel extremely warm and at ease. They looked at the crystal ball in their arms, their hearts filled with joy and excitement.

"We finally found it!" Lin Xiao said happily.

"Yes, but this is just the beginning, we still have a lot of work to do." Li Xuan said calmly.

After returning to the shore, they began to conduct in-depth research and analysis on the exploration of the underwater palace. They carefully studied the contents of those books, trying to understand the theories and methods of time travel.

"It mentions the twisting and folding of time and space, which may be the key." Lin Xiao said, pointing to a passage in the book.

"Well, there is also this. The use of energy is also very important." Li Xuan added.

They also carefully studied those strange instruments, trying to figure out their functions and uses.

"This instrument seems to be used to measure space-time fluctuations." Lin Xiao said.

"What about this?" Li Xuan pointed to another instrument.

"This... I'm not quite sure yet. It requires further research." Lin Xiao frowned.

As for the crystal ball, they were full of curiosity and awe.

"What's so special about this crystal ball?" Lin Xiao asked.

"I think it might be the core device for time travel." Li Xuan guessed.

They began to try various methods to stimulate the power of the crystal ball. They used light and energy to impact it, but the crystal ball still did not respond.

"Is our method wrong?" Lin Xiao said somewhat frustratedly.

"Don't be discouraged, we'll think of other solutions." Li Xuan comforted.

In the following days, Lin Xiao and Li Xuan continued to study the clues of time travel while strengthening their own strength and defense capabilities. They knew that there were many unknown challenges and difficulties waiting for them, but they firmly believed that as long as they united and moved forward courageously, they would be able to realize the dream of time travel and return to their own era.

One day, Lin Xiao suddenly had a new idea.

"Li Xuan, let's try to use the power of our mind to sense the crystal ball." Lin Xiao said.

"The power of the mind?" Li Xuan was a little confused.

"Yes, I think this crystal ball may require us to use our inner strength to communicate with it." Lin Xiao explained.

Li Xuan nodded: "Okay, let's try it."

They closed their eyes, concentrated their minds, and used their hearts to feel the existence of the crystal ball. Gradually, they felt a weak power surging in their hearts.

"There's a reaction!" Lin Xiao shouted excitedly.

They continued to concentrate, and the power grew stronger and stronger. Suddenly, the crystal ball emitted a dazzling light, illuminating the entire room.

"Success!" Li Xuan shouted excitedly.

They looked at the crystal ball, their hearts full of anticipation. As the light flickered, some blurry images appeared on the surface of the crystal ball.

"This is... a different time and space!" Lin Xiao said in surprise.

They saw ancient battlefields, prosperous cities, mysterious planets...

"This is the channel for time travel!" Li Xuan said excitedly.

Lin Xiao and Li Xuan know that they are one step closer to realizing their dream of traveling through time and space. But they also know that there are still many unknown challenges waiting for them. They will take this precious discovery and continue their adventure to pursue the miracle of traveling through time and space...
