Genshin Impact.

After Lin Feng and Li Er went through many hardships, their journey to the mortal world finally came to an end. However, their mission was not over yet.

Lin Feng and Li'er stood on the top of the mountain in the mortal world, overlooking the land where they had experienced disasters. The breeze blew, lifting their hair and clothes. Li'er's eyes flickered with complex lights, with the relief of surviving the disaster, but also confusion about the future.

"Lin Feng, although this ordeal has ended, I still feel empty in my heart." Li'er said softly.

Lin Feng reached out and held Li'er's hand, giving her comfort and strength, "Perhaps it's because we haven't found the true way back to the immortal path yet."

At this moment, the mysterious old man appeared in front of them. The old man's figure looked illusory and mysterious in the sunlight, and his eyes were as deep as the sea, as if he knew everything in the world.

"Children, the end of the catastrophe is just the beginning of a new journey." The old man's voice came slowly.

Lin Feng and Li'er looked at each other, and then bowed to the old man together, "Please give me some advice, Senior."

The old man smiled slightly, waved his long sleeves, and a picture appeared in front of them. The picture showed a fairy mountain shrouded in clouds and mist, with an ancient palace in the mountain, and mysterious runes and light flashing around the palace.

"This is Guixian Palace, the key to your return to the immortal path. But the journey is full of dangers, and you need your wisdom and courage to arrive there." The old man said slowly.

Lin Feng and Li'er nodded without hesitation, "Don't worry, senior, we will do our best."

So, the three of them set out on their journey to Guixian Palace. Along the way, they passed through dense forests, where the roars of beasts could be heard from time to time; they crossed turbulent rivers, where the cold water almost swallowed them; and they climbed steep mountains, where they would be crushed to pieces if they were not careful.

In a valley, they encountered a group of powerful demons. The demons rushed towards them with their fangs and claws bared, spewing black flames from their mouths. Lin Feng and Li'er were not afraid at all. They used their magic and started a fierce battle with the demons. The old man blessed them with magic power and taught them fighting skills.

After a hard fight, they finally defeated the demon, but they were also seriously injured and their magic power was exhausted.

"Kids, hold on, Guixian Palace is just ahead." The old man encouraged them.

Lin Feng and Li'er gritted their teeth and supported each other to move forward. Finally, they saw the legendary Guixian Palace. The gate of the palace was closed and surrounded by a powerful barrier.

Lin Feng and Li Er tried to break the barrier, but their magic power seemed so insignificant in front of the barrier. Just when they were at a loss, the old man came forward and took out a mysterious jade pendant. The jade pendant emitted a soft light, which echoed with the barrier.

Under the effect of the jade pendant, the barrier slowly opened, and the door slowly opened. A powerful immortal power surged out of the palace, enveloping them.

They walked into the palace and saw that the interior was simple and solemn. In the center was a huge statue holding an ancient scroll.

Lin Feng stepped forward and picked up the scroll. The words on the scroll shone with golden light and slowly merged into his mind. It turned out that this was a cultivation method to return to the immortal path.

Lin Feng and Li Er began to practice according to the method, their injuries gradually recovered, and their magic power gradually increased. In the process of practice, their minds were further sublimated, and their understanding of the immortal path became deeper.

After a period of practice, Lin Feng and Li Er finally broke through the bottleneck and successfully returned to the immortal path. When they looked back, the earthly land was gradually fading away.

"We have gained a lot from this ordeal." Li'er said with emotion.

Lin Feng nodded, "Yes, but this is just the beginning. There are more challenges waiting for us in the future."

The old man looked at them with a smile, "Children, you have taken an important step. The future is a long journey, I hope you will not forget your original aspirations and forge ahead."

Lin Feng and Li Er smiled at each other, "Thank you, senior. We will definitely remember this."

Afterwards, their figures gradually disappeared in the fairy light, and they moved towards a higher fairy path.
