The princess arrives and the prosperous Tang Dynasty begins

Lin Xiao and Li Xuan stepped into the mysterious door of time and space. When they stepped over the threshold, a completely unfamiliar and endlessly attractive world appeared before their eyes. What appeared before them was a scene of desolation and mystery. The dilapidated city walls seemed to collapse at any time under the ruthless erosion of the long years. The ancient streets were covered with thick dust and broken stones, as if whispering the tragic fate of this once glorious kingdom.

They stepped carefully on this silent land, and every step they took seemed to touch the heavy pulse of history. The decayed smell in the air, mixed with a faint sadness, lingered around them.

"Is this the lost kingdom?" Lin Xiao asked softly. Her voice echoed in the quiet space with unspeakable awe.

Li Xuan nodded solemnly, his eyes full of curiosity and a strong desire to explore: "It should be. From these ruins, we can vaguely see how prosperous it was in the past."

They walked slowly along the street that seemed to carry endless stories. Although the surrounding buildings were extremely dilapidated, they could still see the ingenious craftsmanship and unique style of the past from the remaining traces. The stone pillars with exquisite carvings and the faded but still gorgeous murals were like messengers of time, leading them back to that glorious era.

They stopped in front of an abandoned palace. The tall gate of the palace was half-closed, as if silently inviting them to explore inside. Lin Xiao and Li Xuan looked at each other, then understood each other and resolutely pushed open the gate.

The palace was dark, and the dust looked like a group of dancing elves under the sunlight. Their footsteps echoed clearly in the empty palace, and seemed particularly clear and lonely. In the hall of the palace, they were pleasantly surprised to find some ancient documents and records.

Li Xuan flipped through these precious documents attentively, his brows gradually furrowed. "These record the history of this kingdom in detail. It turns out that it was once so prosperous, but later it gradually declined due to a terrible disaster."

Lin Xiao came closer and stared at the ancient texts: "What disaster is it?"

Li Xuan continued to read further: "It seems to be a fierce plague. This plague is like a terrible nightmare. It swept across the entire kingdom, ruthlessly taking the lives of countless people, and eventually led to the destruction of the kingdom."

They could not help but feel an inexplicable sadness in their hearts, as if they could deeply feel the pain and despair that those people had experienced. Then, they unexpectedly found a secret room deep in the palace. The door of the secret room was tightly closed, but there were some strange symbols and patterns engraved on it, which made people puzzled.

"What is this?" Lin Xiao asked curiously, with a puzzled gleam in his eyes.

Li Xuan studied the mysterious symbols carefully: "I think this may be some kind of code or mechanism. Perhaps it hides more important secrets of this kingdom."

So, they began to concentrate on trying to crack the code. Time passed by, and after racking their brains, they finally found the key to open the secret room. With a dull sound, the secret room door slowly opened, and an old smell came to the face, which seemed to contain the precipitation of years.

There were some precious items and documents neatly placed in the secret room, among which there was an ancient book that was particularly eye-catching and instantly attracted their attention. Li Xuan carefully picked up the book and gently opened the first page.

"It records some mysterious legends and secrets of this kingdom." Li Xuan's voice was filled with uncontrollable excitement. "It is said that this kingdom once possessed an incomparable and powerful treasure that could give people endless power and wisdom."

Lin Xiao's eyes suddenly lit up, like bright stars: "Then we must find this treasure!"

With full of expectations, they followed the guidance of the map and moved forward firmly towards the location of the treasure. Along the way, they encountered all kinds of unimaginable difficulties and obstacles, including rugged roads, ferocious beasts, and unpredictable natural traps, but they never gave up, and the faith in their hearts was like a burning flame, burning stronger and stronger.

Finally, they came to the place where the treasure was. It was an ancient temple, and the walls of the temple were engraved with mysterious runes, like mysterious spells. They walked into the temple carefully, and in the depths of the temple, they found a box emitting a strange light.

"Is this the treasure?" Lin Xiao asked softly, with a hint of nervousness and anticipation in his voice.

Li Xuan nodded, his expression became particularly serious, and he carefully opened the box. Inside the box, there was a crystal clear gem, which emitted a soft light, as if it contained endless power and wisdom, and that light seemed to be able to illuminate the whole world.

Just as they were about to pick up the gem, suddenly, a sinister laugh sounded in the temple. They turned their heads and saw a dark figure slowly emerging.

"Haha, do you think you can take this treasure away easily?" The black shadow sneered, with endless chillness in his voice.

Lin Xiao and Li Xuan's hearts tightened, and they looked at the black shadow warily: "Who are you?"

"I am the guardian of this kingdom. I will not let you take away the treasures that belong to this kingdom." said the black shadow, and the voice seemed to come from the depths of hell.

A fierce battle broke out instantly, and Lin Xiao and Li Xuan fought a desperate battle with the black shadow. During the battle, they gradually discovered the black shadow's weaknesses, and finally defeated him successfully with tacit understanding and courage.

Holding the precious gem, they walked out of the temple, the sun shining on them as if cheering for their victory.

"What should we do with this treasure?" Lin Xiao asked thoughtfully.

Li Xuan thought for a moment, his eyes revealing a determined light: "Maybe we should bring it back to our world and let more people know the story and secrets of this lost kingdom."

Lin Xiao nodded and said in agreement: "Okay, then let's take it back."

They took the gem and went through the gate of time and space again and returned to their own world. They shared this wonderful experience and the precious gem with people, allowing more people to understand the tragic history and important secrets of the lost kingdom. And their adventure will continue to shine with unique light in the long river of time, just like the eternal stars.

In the days that followed, Lin Xiao and Li Xuan often recalled every detail of their time in the lost kingdom. The ancient buildings, mysterious codes, precious treasures, and the fierce battle were all deeply imprinted in their minds like a brand. They knew that this experience would become the most precious treasure in their lives, accompanying them forever and inspiring them to explore more unknown worlds and pursue more truth and wisdom. And the lost kingdom would also remain in their hearts forever, becoming a unique memory deep in their souls.
