Genshin Impact.

After experiencing the difficult choices in the adverse tide, Lin Feng, Li Er and the old man embarked on a more complicated and confusing immortal journey. Their journey to the mortal world this time is destined to be full of countless challenges and opportunities.

Lin Feng stood tall, his eyes revealing determination and courage. He was dressed in a green robe, with an ancient long sword on his waist, and mysterious runes engraved on the scabbard. Li'er was as beautiful as a fairy. She was dressed in a white dress, her long hair was like a waterfall, and her eyes were shining with a smart light. The old man was white-haired, but energetic. He was dressed in a gray robe and held a cane in his hand, which was inlaid with a sparkling gem.

They came to a strange place with picturesque scenery. However, they knew that under this beautiful appearance, there were countless dangers. Lin Feng took a deep breath and felt the surrounding atmosphere. He could feel that the spiritual energy here was much thinner than the place they were in before, but it was also full of a mysterious power.

"Is this the place where we will experience the tribulation?" Li'er asked softly.

The old man nodded slightly. "Yes, this place is full of unknown dangers and opportunities. We must proceed with caution."

They began to explore the place. Along the way, they encountered all kinds of creatures. There were cute elves and ferocious beasts. Lin Feng was always alert, holding the sword tightly in his hand. Li Er used her magic to protect herself and her companions. The old man watched from the side and gave them some guidance from time to time.

During the exploration, they found a mysterious cave. The entrance of the cave exuded a mysterious atmosphere, which made people curious. Lin Feng hesitated for a moment, then said: "Let's go in and take a look. Maybe there are treasures or clues in it."

Li'er said worriedly, "Will it be dangerous?"

The old man smiled slightly, "Where there is danger, there is opportunity. Since we are here to experience disaster, we cannot be afraid of danger."

So they walked into the cave carefully. The cave was dark and damp, with a faint light flickering on the wall. They walked carefully, always alert to the movement around them. Suddenly, a huge spider swooped down from the top of the cave. The spider's body was huge, more than a person's height, and its eyes flashed red light, which made people shudder.

Lin Feng immediately drew out his sword and faced the spider. His swordsmanship was sharp and every move was full of power. Li'er also used magic, shooting rays of light at the spider. The old man chanted a spell to bless them with strength.

After a fierce battle, they finally defeated the spider. The spider's body fell to the ground, emitting a foul odor. Lin Feng wiped the sweat from his forehead and said, "This spider is really powerful."

Li'er nodded, "Fortunately we worked together, otherwise it would be difficult to deal with it."

They continued to go deeper into the cave. Deep in the cave, they found an ancient book. The cover of the book was worn out, but the words on it were still clearly visible. Lin Feng picked up the book and opened it. It contained some methods and techniques of practicing immortal arts.

"This is a secret book of immortal arts!" Lin Feng said excitedly.

Li'er and the old man also gathered around and studied the secret book together. They found that the immortal arts recorded in the secret book were very profound and required them to spend a lot of time and energy to practice.

"Let's practice here." said the old man.

So, they found a quiet place in the cave and began to practice the magic. Lin Feng adjusted his breath according to the method in the secret book and guided the spiritual energy into his body. He could feel a strong force surging in his body. Li'er was also practicing seriously at the side, and her magic became more and more sophisticated.

After a period of training, their magic skills have greatly improved. Lin Feng's swordsmanship has become more powerful, and Li'er's magic skills have become more magical. The old man watched them with satisfaction, his heart full of expectations.

However, their practice did not last long. Suddenly, there was a violent tremor in the cave. They stood up in horror, not knowing what had happened.

"Is there some powerful creature approaching?" Li'er said worriedly.

Lin Feng gripped his sword tightly, "No matter what it is, we must deal with it carefully."

They walked out of the cave carefully and found that the world outside had changed dramatically. The sky was covered with dark clouds, lightning and thunder. Huge cracks appeared on the ground, as if the end of the world was approaching.

"What's going on?" Lin Feng asked in horror.

The old man frowned, "This may be the beginning of our tribulation. We must be prepared."

They began to look for clues everywhere, trying to understand the cause of the disaster. In the process of searching, they met some other immortal cultivators. These immortal cultivators were also struggling to survive. They exchanged information with each other and worked together to find a solution to the problem.

In the communication with other immortal cultivators, they learned that the disaster was caused by an evil force. This evil force attempted to destroy the world and establish its own rule. Lin Feng, Li Er and the old man decided to join the team of other immortal cultivators to fight against this evil force.

They started a tough battle. The evil forces were very powerful, and they possessed all kinds of evil magic and weapons. Lin Feng, Li Er and the old man relied on their magic and courage to fight against the evil forces.

In the battle, they encountered various dangers. Sometimes, they were hit by the magic of evil forces and were seriously injured. Sometimes, they fell into the enemy's trap and faced life and death tests. But they never gave up, and relied on their firm belief and tenacious perseverance to overcome difficulties again and again.

In a battle, Lin Feng was unfortunately hit by the enemy's magic and was seriously injured. Li'er and the old man immediately took him to a safe place to treat his injuries. Li'er used her magic to heal Lin Feng. The old man chanted a spell to bless Lin Feng with strength.

After a period of treatment, Lin Feng's injuries gradually recovered. He looked at Li'er and the old man with gratitude and said, "Thank you. If it weren't for you, I might have died."

Li'er smiled slightly, "We are companions, and it is only natural for us to help each other."

The old man nodded. "Now is not the time to talk about this. We must find the core of the evil forces as soon as possible and destroy them completely."

They continued to move forward, and in the process of searching for the core of the evil forces, they encountered many difficulties and challenges. Sometimes, they would lose their way and didn't know where to go. Sometimes, they would encounter powerful enemies and had to pay a huge price to defeat them. But they never gave up, and with courage and wisdom, they approached the truth step by step.

Finally, they found the core of the evil forces. It was a huge castle, surrounded by evil magic and traps. Lin Feng, Li Er and the old man walked into the castle carefully, ready for the final battle with the evil forces.

Inside the castle, the leader of the evil forces was sitting on a huge throne, his eyes revealing endless evil and arrogance. He looked at Lin Feng, Li Er and the old man, and sneered: "Do you think you can defeat me? You are too naive."

Lin Feng looked at the leader of the evil forces without fear, "We will definitely defeat you and save the world."

The leader of the evil forces laughed, "Then let me see your strength."

As soon as he waved his hand, countless evil creatures rushed out from all directions. Lin Feng, Li'er and the old man immediately prepared for battle. They used their strongest magic and started a fierce battle with the evil creatures.

During the battle, they discovered that the leader of the evil forces was very powerful, and his magic was almost invincible. Lin Feng, Li Er and the old man were in trouble, and they didn't know how to defeat this powerful enemy.

Just when they were in despair, Lin Feng suddenly remembered the secret book of immortal arts they had obtained in the cave. He opened the secret book and studied the contents carefully. Finally, he found a powerful immortal art that could fight against the leader of the evil forces.

Lin Feng immediately performed this magic, and a powerful light shot out from his hand, directly hitting the leader of the evil forces. The leader of the evil forces screamed, and his body began to gradually dissipate.

As the leader of the evil forces was defeated, the evil creatures also disappeared. The dark clouds in the sky dissipated, and the sun shone on the earth again. Lin Feng, Li'er and the old man sat on the ground tiredly, their hearts filled with joy and a sense of accomplishment.

They know that their tribulations are not over yet, but they have taken an important step. They will continue to move forward, explore this mysterious world, and find more immortal fates and opportunities. And their story will also be passed down in this world and become a legend.
