Genshin Impact.

After Lin Feng realized it, he continued on his way forward. Li'er accompanied him, and their figures seemed small but firm in this vast world.

They came to an ancient town where people lived peacefully, but Lin Feng keenly sensed a hint of something unusual. In a corner of the town, a mysterious old man caught their attention.

The old man was in ragged clothes, but his eyes were deep, as if he knew everything in the world. Lin Feng went up to talk to the old man, who smiled and said, "Young man, your immortal journey is full of ups and downs, but as long as you look to the light, you will have nothing to fear."

Lin Feng and Li Er looked at each other, thinking deeply. They decided to stay in the town for a while to explore the secrets hidden in it.

At night, a strange fog suddenly filled the town. Lin Feng became alert and pulled Li'er forward carefully. In the fog, they heard faint cries and calls for help.

Following the direction of the sound, they came to an abandoned temple, where a dark figure was performing an evil ritual, and the surrounding souls were bound and struggling in pain.

Lin Feng was furious and rushed towards the dark figure with his sword. Li Er cast a spell to try to rescue the trapped soul. The dark figure sneered and exerted a powerful dark force to start a fierce battle with Lin Feng.

During the battle, Lin Feng gradually discovered that the power of the dark figure was inextricably linked to the hardships he had experienced before. A strong sense of mission surged in his heart, and he must defeat this darkness in order to make his immortal path brighter.

Li'er kept casting spells for Lin Feng, her eyes were firm and full of trust in Lin Feng. Lin Feng was encouraged and his swordsmanship became more and more fierce. He finally found the flaw of the dark figure and defeated it in one fell swoop.

As the dark figure disappeared, the trapped souls were freed and the fog gradually dissipated. The town returned to its former tranquility.

However, Lin Feng knew that this was just a small episode on the way to immortality. They continued to move forward and came to a mysterious forest. The forest was filled with strange light, as if it hid endless treasures and dangers.

Lin Feng and Li'er stepped into the forest cautiously, hearing whispers in their ears. These whispers seemed to be tempting them and making them lose their way. But Lin Feng remained unmoved with his firm will.

Deep in the forest, they found an ancient ruin. The door of the ruin was closed and engraved with mysterious runes. Lin Feng carefully observed the runes, trying to find a way to open the door.

At this moment, a group of mysterious creatures emerged from the ruins and attacked them. These creatures had different shapes and possessed powerful strength. Lin Feng and Li'er fought side by side and fought a desperate battle with these creatures.

After a hard fight, they finally repelled these creatures. Lin Feng also learned new spells in the battle and successfully opened the door to the ruins.

After entering the ruins, they found that it was full of various tests and puzzles. Each level required them to use their wisdom and strength to pass.

In one of the levels, they encountered a huge mirror. The mirror reflected their deepest fears and desires. Lin Feng looked at himself in the mirror, and the confusion and bewilderment he had felt before came back to him.

Li'er held Lin Feng's hand and said softly: "Lin Feng, don't be fooled by the mirror. We must believe in our own hearts." Lin Feng took a deep breath, calmed himself, and finally broke the illusion of the mirror and passed this level.

After many tests, they finally came to the core of the ruins, where they found an ancient secret book that recorded powerful immortal methods and ways of cultivation.

Lin Feng and Li Er were overjoyed and decided to concentrate on training here to improve their strength. During the training process, Lin Feng's mind became purer and his understanding of the immortal path became deeper.

When they left the ruins, they were reborn. They continued to move forward, facing more challenges and opportunities. The road to immortality was long, but they looked to the light and were fearless.
