Autobiography of Li Yunfei, a time traveler

Li Yunfei, Lin Yue and Zhang Hao were standing in an unfamiliar land, surrounded by a lush forest. The sunlight shone through the gaps between the leaves, forming patches of light and shadow.

"Where is this?" Lin Yue looked around, bewildered.

Li Yunfei frowned and observed the surrounding environment: "I don't know, but it feels very unusual here."

Zhang Hao stretched his muscles and said, "Never mind, let's walk around and take a look first."

The three of them walked cautiously into the depths of the forest. After walking for a while, they heard the sound of gurgling water.

"There's the sound of flowing water over there, maybe we'll find something there." Li Yunfei said, quickening his pace.

They walked in the direction of the sound and saw a clear stream, the water flowing gently and sparkling in the sun.

"Wow, so beautiful!" Lin Yue couldn't help but exclaim in admiration.

Li Yunfei squatted down, scooped up some stream water with his hands, and washed his face: "The water here is so cool."

Just then, there was a strange movement in the woods not far away.

"Shh, there's some noise." Li Yunfei stood up alertly and signaled everyone to be quiet.

The three of them stood there quietly, staring at the woods. Then a snow-white fox jumped out of the woods, its eyes smart and cunning.

"It's a fox." Zhang Hao said softly.

The fox looked at them, then turned and ran deeper into the woods.

"Hurry up and follow it!" Li Yunfei shouted.

They followed the fox through the woods. The fox was so fast that they almost couldn't keep up several times.

"Where is this fox taking us?" Lin Yue said breathlessly.

Li Yunfei said as he ran: "I don't know, but there must be a purpose."

Finally, the fox stopped in front of a mountain wall, looked back at them, and then went into a cave.

"There!" Zhang Hao said, pointing to the cave.

Li Yunfei hesitated for a moment, then said, "Let's go in and take a look."

The three of them walked into the cave carefully. The cave was dark and damp, and filled with a bad smell.

"Be careful." Li Yunfei reminded.

They walked slowly, when suddenly, a low roar came from the front.

"Oh no, there's something!" Li Yunfei shouted.

I saw a huge black bear rushing out from the depths of the cave, with its bloody mouth wide open and fierce light flashing in its eyes.

"Run!" Zhang Hao shouted.

The three turned and ran, but the black bear was very fast and soon caught up with them.

Li Yunfei stopped and drew his sword: "You go first, I'll hold it back!"

"No, let's go together!" Lin Yue shouted.

"Stop talking nonsense and go!" Li Yunfei shouted.

Zhang Hao pulled Lin Yue and turned to run out of the cave.

Li Yunfei faced the black bear, took a deep breath, and used all his strength to fight the black bear.

The black bear waved its huge paw and pounced on Li Yunfei. Li Yunfei dodged sideways and then stabbed the black bear in the abdomen with a sword.

The black bear roared angrily and attacked Li Yunfei even more frantically.

Li Yunfei gradually felt exhausted under the attack of the black bear, but he still resisted tenaciously.

Just then, Zhang Hao and Lin Yue ran back.

"We're here to help you!" Zhang Hao shouted.

Lin Yue cast a spell, and rays of light shot towards the black bear.

With the joint efforts of the three people, the black bear was finally knocked to the ground.

"Huh, it's finally solved." Li Yunfei said, panting.

"Are you okay?" Lin Yue asked with concern.

Li Yunfei shook his head: "I'm fine, let's move on."

They continued to walk deeper into the cave, and after a while, they found some strange symbols and patterns in the cave.

"What are these?" Zhang Hao asked.

Li Yunfei looked at these symbols and patterns carefully: "It looks like some kind of ancient formation."

"Formation? What should we do then?" Lin Yue said anxiously.

Li Yunfei thought for a while, then said: "Let's be careful and see if we can find a way to crack it."

They carefully moved through the formation, and suddenly, the ground began to shake violently.

"Oh no, the formation has been activated!" Li Yunfei shouted.

Rays of light shot out from the surrounding walls, enveloping them.

"Ah!" Lin Yue screamed.

Li Yunfei held Lin Yue and Zhang Hao tightly and said, "Don't be afraid, we will definitely find a way out!"

They were trying hard to find a way out in the light, and suddenly, Li Yunfei found a bright spot.

"Look, there!" Li Yunfei shouted.

They ran towards the flashing light, and as they got closer, a powerful force sucked them in.

When they opened their eyes again, they found themselves in a strange place...
