Genshin Impact.

Lin Feng and Li'er were exhausted physically and mentally in the battle between light and shadow, but the gears of fate did not stop turning.

They woke up in a desolate valley, surrounded by thick fog, making it difficult to tell the direction. Lin Feng looked around vigilantly, while Li'er followed closely beside him.

At this moment, a mysterious old man appeared in front of them. The old man's eyes were deep, as if he knew everything in the world. He looked at Lin Feng and Li'er, and slowly said: "Your journey has just begun. This chaotic land hides countless secrets and challenges."

Lin Feng bowed and asked, "Senior, may I ask how we should move forward?"

The old man smiled slightly, handed over a mysterious jade pendant, and said: "This jade pendant can guide you at critical moments, but remember, the real power comes from within."

After Lin Feng and Li Er thanked them, they continued on their way. Along the way, they encountered all kinds of strange scenes and powerful monsters. Sometimes there were violent storms, lightning and thunder; sometimes there were thick fogs and illusions.

When crossing a swamp, Li'er accidentally fell into a quagmire. Lin Feng reached out to pull her without hesitation, but was dragged down with her. The two struggled desperately in the quagmire and were about to be drowned. At the critical moment, Lin Feng remembered the old man's words. He calmed down, used the spiritual power in his body, and finally broke free from the shackles of the quagmire.

After several days of hard journey, they arrived in front of an ancient castle. The castle gate was closed and there was a gloomy atmosphere around it. Lin Feng and Li'er mustered up the courage to push open the gate, and it was pitch black inside.

Suddenly, a group of ghostly figures rushed towards them. Lin Feng waved his sword and started a fierce battle with these ghosts. Li Er cast spells on the side to provide support for Lin Feng.

After a hard fight, they finally defeated the ghost. However, there are more dangers waiting for them in the castle.

Deep in the castle, they found a mysterious ancient book that contained a powerful spell, but it required solving a series of complex puzzles to obtain it.

Lin Feng and Li Er began to concentrate on studying these puzzles. They discussed with each other, thought together, and finally solved one puzzle after another.

When the last puzzle was solved, a powerful force surged into their bodies. However, this force was too strong for them to control for a while.

At this moment, the castle began to shake violently and seemed to be about to collapse. Lin Feng and Li Er ran out with all their might.

At the exit, they encountered another huge monster, which attacked them with its claws and fangs bared.

Lin Feng and Li'er worked hand in hand to exert their newly acquired powers to the fullest. After a thrilling battle, they finally defeated the monster and escaped from the castle.

At this time, they found that the jade pendant in their hands emitted a dazzling light, guiding them to a mountain.

The mountain peaks were towering into the clouds, and the mountain roads were rugged and difficult to walk on. But Lin Feng and Li'er did not back down. They supported each other and climbed up step by step.

Finally, they reached the top of the mountain. They were stunned by the scene before them: a beautiful fairyland appeared before their eyes, surrounded by clouds and mist, and filled with fairy music.

In the fairyland, they met an immortal who told them that this was the key place for them to go through the tribulation. Only by passing the final test could they truly complete the tribulation and return to the immortal path.

Lin Feng and Li Er took a deep breath and prepared to face the final challenge...
