Autobiography of Li Yunfei, a time traveler

Li Yunfei and Lin Ya approached the castle quietly. They found that the castle gate was closed and there were no other entrances around.

"What should we do?" Lin Ya said anxiously.

Li Yunfei carefully observed the castle wall and said, "Let's see if we can find another way to get in."

They slowly groped along the wall of the castle, and suddenly Li Yunfei found some not-so-obvious cracks on the wall.

"It seems a little different here." Li Yunfei said.

Lin Ya came over to take a look and asked, "Is there some kind of trap?"

Li Yunfei nodded and began to study the gaps carefully. After some attempts, he finally found a way to open the mechanism.

With a slight noise, a secret door appeared in the wall.

"Found it!" Li Yunfei said excitedly.

They walked carefully into the secret door, which led to a narrow passageway filled with an old atmosphere and with faint lights flickering on the walls.

"Be careful." Li Yunfei reminded.

They walked slowly along the passage, and after a while, the passage suddenly opened up and a spacious hall appeared.

There are all kinds of strange objects in the hall, some of which emit mysterious light.

"What are these things?" Lin Ya asked curiously.

Li Yunfei was not sure either. "I don't know, but it feels very unusual."

They looked around the hall and suddenly heard footsteps.

"Someone is coming!" Li Yunfei quickly pulled Lin Ya to hide in a corner.

I saw a group of people in black robes walking into the hall, they seemed to be looking for something.

"What are they looking for?" Lin Ya asked in a low voice.

Li Yunfei shook his head. "I don't know, but it must be related to what they took from the ruins."

The group of men in black robes searched the hall for a while, but didn't find what they wanted, so they left cursing.

"They left." Lin Ya breathed a sigh of relief.

Li Yunfei walked out from the corner and said, "Let's keep looking. Maybe we can find some clues."

They continued to explore the hall, and suddenly Lin Ya found an ancient book.

"What is this?" Lin Ya picked up the book, opened it and took a look.

"I can't understand the words above." Lin Ya frowned.

Li Yunfei took the book and took a look. "The words on it seem to be an ancient spell."

"Spell? What's the use of that?" Lin Ya asked.

Li Yunfei thought for a moment and said, "I don't know, but maybe it has something to do with the secret of this castle."

They continued to explore the castle with the books, and deep in the castle, they found a huge secret room.

There was a huge coffin in the secret room, which was engraved with runes.

"What is this?" Lin Ya said in surprise.

Li Yunfei walked forward and looked at the coffin carefully. "I don't know, but it feels very unusual."

They circled the coffin several times, and suddenly the runes on the coffin flickered and emitted a ray of light.

"Oh no, get out of the way!" Li Yunfei shouted.

They stepped back quickly, only to see the coffin slowly open and a figure sitting up from inside.

He was an old man wearing a black robe, his face was covered with wrinkles and there was a strange light in his eyes.

"Who are you? Why are you here?" The old man's voice was low and hoarse.

Li Yunfei and Lin Ya looked at the old man warily, "We broke in accidentally."

The old man sneered, "Humph, you accidentally broke in? Do you think I would believe it?"

"We really just came in to take a look out of curiosity," Lin Ya explained quickly.

The old man looked at the books in their hands and said, "Give me that book."

Li Yunfei held the book tightly in his hand. "We found this. Why should we give it to you?"

A hint of murderous intent flashed in the old man's eyes, "If you don't give it to me, don't even think about leaving here alive."

As he spoke, the old man raised his hand and waved it, and a powerful force attacked them.

Li Yunfei and Lin Ya quickly cast spells to resist, but the old man's power was too strong and they were still pushed back a few steps.

"Let's go!" Li Yunfei shouted.

They turned and ran, with the old man chasing them closely.

They fled desperately in the castle and finally ran to the roof of the castle.

"What should we do?" Lin Ya said anxiously.

Li Yunfei looked at the old man who caught up with him and said, "Fight him!"

They cast spells again and started a fierce battle with the old man. The old man was very powerful, and Li Yunfei and Lin Ya gradually fell into a disadvantage.

Just when they thought they couldn't hold on any longer, Lin Ya suddenly thought of the ancient book.

"Yun Fei, try using the spell in that book." Lin Ya shouted.

Li Yunfei suddenly realized, and quickly took out the book and recited the spell on it.

As the spell was recited, a light emanated from the book, enveloping the old man.

The old man let out a scream and his body began to twist and deform.

"Success!" Lin Ya said excitedly.

After a while, the old man disappeared, leaving only ashes on the ground.

"Finally solved." Li Yunfei breathed a sigh of relief.

They sat on the roof to rest for a while and then began to think about what to do next.

"There must be many secrets in this castle. Should we continue exploring?" Lin Ya asked.

Li Yunfei nodded, "Well, let's look for it again."

They came down from the roof and continued to explore the castle. In one of the rooms in the castle, they found a huge map.

"What kind of map is this?" Lin Ya asked curiously.

Li Yunfei looked at the map carefully. "It seems to be the structural diagram of this castle, and some other places."

They found some marks on the map that seemed to be some hidden treasures or secret places.

"Let's look for it according to the map." Li Yunfei said.

They searched around the castle according to the map, and finally found a hidden treasure house.

The treasury is filled with all kinds of treasures, including precious gems, powerful magic weapons, ancient secrets and so on.

"Wow, so many treasures!" Lin Ya said excitedly.

Li Yunfei was also surprised, "These treasures must be very valuable."

They picked out some useful treasures from the treasury and then left.

It was dark when they came out of the castle.

"Let's find a place to rest first." Li Yunfei said.

Lin Ya nodded, "Okay, let's continue exploring tomorrow."

They found a safe place nearby and rested for the night. The next day, they continued their journey of exploration.
