Genshin Impact.

After going through numerous hardships and obstacles, Lin Feng finally found a glimmer of hope in breaking through the fog and seeking the truth. However, at this moment, he did not relax at all, because the road ahead was still full of unknowns and challenges.

Li'er accompanied Lin Feng, her eyes full of determination and trust. They followed the mysterious old man and continued on this long journey to immortality.

The old man led them to a deep valley filled with thick fog, making it difficult to see the road ahead. Lin Feng felt a little alert, but he did not retreat. Instead, he tightened his sword.

"Lin Feng, there is a mysterious power hidden in this valley that may help you break through your current predicament." The old man said slowly.

Lin Feng nodded and stepped into the valley carefully. As soon as he entered, he felt a strong pressure coming towards him. Li'er screamed, and Lin Feng quickly protected her behind him.

They were moving forward with difficulty in the valley, when suddenly, a group of strange creatures appeared around them. Their figures were blurry and they exuded a strange aura. Lin Feng was not afraid at all and used his magic to fight them fiercely.

During the battle, Lin Feng discovered that these creatures were not ordinary monsters, they seemed to be controlled by some mysterious force. After a hard fight, Lin Feng finally repelled these creatures.

However, before they could catch their breath, something changed in the valley. The originally calm ground began to shake violently, and huge cracks spread out.

Lin Feng and Li Er quickly evaded, but found that the retreat route had been blocked. Just when they were in a desperate situation, Lin Feng suddenly felt a mysterious force guiding him.

He followed the guidance of this power and came to the depths of the valley, where they found an ancient stone tablet engraved with mysterious runes.

Lin Feng studied these runes carefully, trying to find the key to breaking the deadlock. Li'er waited anxiously on the side, her heart full of worry.

After much contemplation, Lin Feng finally understood the secret of the rune. He used his magic to activate the power on the stone tablet, and a beam of light shot up into the sky, illuminating the entire valley.

As the light faded, they found themselves in a mysterious space. The space was filled with powerful immortal power, and Lin Feng felt that his cultivation began to improve under the nourishment of this immortal power.

Li'er also benefited a lot, and her magic was further strengthened.

Just as they were immersed in this power, the space suddenly began to collapse. Lin Feng and Li'er quickly fled, and at the critical moment, they finally returned to the real world.

However, they found themselves in a strange place, surrounded by a barren desert with no sign of life.

"Where is this?" Li'er asked.

Lin Feng frowned and shook his head. "I don't know, but I believe that as long as we keep moving forward, we will find a way out."

They walked hard in the desert, and the scorching sun made them exhausted. But Lin Feng never gave up, and the belief in his heart supported him to keep moving forward.

Finally, when they were about to despair, they saw an ancient city in the distance. They quickened their pace and walked towards the city.

After entering the city, they found that the people here were indifferent and wary of them. Lin Feng tried to communicate with them, but no one responded.

During his exploration of the city, Lin Feng discovered some secrets about the city. It turned out that the city had suffered a terrible disaster, causing people to lose hope and trust.

Lin Feng decided to help them. He used his magic to bring life and vitality to the city. People gradually smiled and were grateful to Lin Feng.

After leaving the city, Lin Feng and Li Er continued on their immortal journey. Their figures gradually faded away in the afterglow of the setting sun, but their story continued...
