Autobiography of Li Yunfei, a time traveler

Li Yunfei obtained important information from the crystal ball. He learned that in the far north of this world, there is an ancient teleportation array, and through this teleportation array, he may be able to return to his own world. However, it is not easy to reach the far north, and the road is full of difficulties and obstacles.

Li Yunfei packed his bag, took the treasures he got from the ruins, and resolutely embarked on a journey to the Far North. He walked along a winding path, surrounded by dense forests and steep mountains.

After walking for a few days, Li Yunfei came to a swamp. The swamp was filled with a foul smell, which made people feel very uncomfortable. Li Yunfei carefully looked for a path to pass through the edge of the swamp. Suddenly, a huge crocodile jumped out of the swamp and pounced on him with its bloody mouth wide open.

Li Yunfei reacted quickly, dodging the crocodile's attack by leaning sideways, then swung his sword and slashed at the crocodile. The crocodile had thick skin and flesh, and the sword only left a shallow scar on it. The crocodile was enraged and attacked Li Yunfei even more frantically.

While dodging the crocodile's attack, Li Yunfei was looking for the crocodile's weakness. After some observation, he found that the crocodile's eyes were its most vulnerable spot. So, Li Yunfei seized the opportunity and stabbed the crocodile's eyes with a sword.

The crocodile screamed, fell to the ground, struggled a few times, and then stopped moving. Li Yunfei breathed a sigh of relief and continued to move forward.

A few days later, Li Yunfei encountered a mountain that towered into the clouds. The mountain was extremely steep, with almost no place to climb. Li Yunfei looked at the mountain in front of him and felt a little worried.

But he did not back down, but began to look for other ways. He found a hidden path at the foot of the mountain, and after walking along the path for a distance, he came to a cave.

Li Yunfei walked into the cave carefully. There was a mysterious atmosphere in the cave. He walked forward along the cave and suddenly heard a low roar.

Li Yunfei stopped cautiously, holding the sword tightly in his hand. A huge black bear walked out from the depths of the cave, staring at Li Yunfei fiercely with a pair of bloodshot eyes.

Li Yunfei knew that this was another fierce battle, but he was not afraid, he held up his sword and rushed towards the black bear. The black bear waved its huge paw and started a fierce fight with Li Yunfei.

During the battle, Li Yunfei found that although the black bear was powerful, its movements were relatively slow. He used his agility to constantly dodge the black bear's attacks, and then took the opportunity to inflict damage to the black bear.

After a hard fight, Li Yunfei finally succeeded in defeating the black bear. He sat on the ground tiredly, took a short rest, and continued to explore the cave.

Deep in the cave, Li Yunfei found some ancient words and patterns. He studied them carefully and found that they seemed to be related to the path leading to the Far North.

Li Yunfei was very excited. He memorized these words and patterns firmly in his mind and then left the cave.

On the way forward, Li Yunfei encountered various strange creatures and dangerous traps, but he relied on his tenacious will and intelligence to escape danger time and time again.

Finally, after a long journey, Li Yunfei arrived in the far north, a world of ice and snow, with biting cold winds that made it almost impossible to breathe.

Li Yunfei was searching for the ancient teleportation array in the far north. After unremitting efforts, he finally found the location of the teleportation array. However, the teleportation array was surrounded by a powerful barrier, and it was not easy to break this barrier.

Li Yunfei was in trouble again, but he did not give up. He began to think about how to break this barrier...
