Genshin Impact.

Lin Feng and Li'er had a brief respite during the difficult journey of breaking the catastrophe and searching for the truth. However, the wheel of fate did not stop turning, and new tests followed.

They took a short break in a quiet valley. Lin Feng looked up at the sky, his mind full of thoughts. Li Er accompanied him quietly, her clear eyes showing determination and tenderness.

At this time, a mysterious old man appeared in front of them. The old man had deep eyes, as if he knew everything in the world.

"Children, you still have a long way to go, and the hardships ahead will be even more severe." The old man's voice was low and powerful.

Lin Feng bowed and saluted, "Thank you for your guidance, senior. We will move forward courageously."

The old man nodded slightly, "Next, you need to go to a place called 'Illusion Valley', where you will find the key to your pursuit of your true self."

Upon hearing this, Lin Feng and Li'er embarked on a new journey without hesitation.

Huanxin Valley was filled with clouds and mist, and was full of mystery. Lin Feng and Li'er walked into the valley carefully. The scene around them was like a dream, making it difficult to distinguish between reality and illusion.

"Lin Feng, it's so weird here, we have to be careful." Li'er said softly.

Lin Feng held her hand tightly, "Don't be afraid, I'm here."

As they moved forward in the valley, they encountered various strange scenes and illusions from time to time. Sometimes it was a beautiful scene of blooming flowers, which made people intoxicated; sometimes it was a gloomy and terrifying scene, which made people shudder.

In a hallucination, Lin Feng saw his past failures and mistakes. Those painful memories came flooding back like a tide, almost making him fall into despair.

"Lin Feng, this is not true, you need to wake up!" Li'er's cry pulled him back from his decadence.

And Li'er also saw the scene she feared most, losing Lin Feng, in another illusion, and couldn't help but burst into tears.

Lin Feng comforted her, "This is just an illusion, we will not be separated."

They supported each other and tried to get rid of one illusion after another.

After a difficult struggle, they finally came to the depths of Huanxin Valley, where there was an ancient stone tablet engraved with mysterious runes.

Lin Feng studied these runes carefully, trying to find clues from them.

"Lier, I feel like these runes seem to be telling a story about the heart." Lin Feng said thoughtfully.

Li'er also came over, "Maybe this is the key to our search for our true self."

Just as they were concentrating on the stone tablet, a group of dark shadows suddenly appeared around them, pouncing towards them with their fangs and claws bared.

Lin Feng and Li'er reacted quickly, using their respective magic powers to engage in a fierce battle with the black shadow.

However, as the shadows grew in number, they gradually felt overwhelmed.

"This is not a solution. We must find the weakness of the black shadow." Lin Feng said.

Li'er suddenly had an idea, "Could it be related to these runes?"

Lin Feng suddenly realized, and they looked at the runes on the stone tablet again and finally discovered the secret.

With their understanding of runes, they successfully repelled the shadow.

At this moment, the stone tablet emitted a dazzling light, and a mysterious portal appeared in front of them.

Lin Feng and Li'er looked at each other and walked into the door without hesitation.

The world behind the door was a peaceful and tranquil scene, and they seemed to have found their inner home.

"Perhaps, this is the truth we have been pursuing." Lin Feng said with emotion.

Li'er smiled and nodded, "But our immortal journey is not over yet."

With new insights and strength, they left Huanxin Valley and continued on their original immortal journey, facing more challenges and opportunities.
