Genshin Impact.

After experiencing a shocking change in their immortal path, Lin Feng and Li Er fell into an unprecedented predicament. However, their determination to become immortals never wavered.

At this time, they were in a desolate valley, surrounded by strange fog, making it difficult to tell the direction. Lin Feng held the sword tightly in his hand, staring firmly ahead, while Li'er followed closely beside him, looking a little nervous.

"Brother Lin Feng, this place is so weird, we have to be careful." Li'er said softly.

Lin Feng nodded slightly, "Don't be afraid, I'm here."

At this moment, a gust of wind whistled by, mixed with sharp cries. Lin Feng and Li'er instantly became alert, and saw a group of huge black birds flying towards them. The eyes of these birds flashed red, and their sharp claws seemed to be able to tear everything apart.

Lin Feng used his magic, and the magic sword in his hand shone with dazzling light, turning into sword energy that shot towards the bird. Li'er was not to be outdone, and she waved her hands, releasing magic light, fighting side by side with Lin Feng.

After a fierce battle, they finally repelled the bird. But before they could catch their breath, the ground suddenly began to shake violently, and a huge python emerged from the ground. The python had a sturdy body, and its scales flashed with a cold light.

Lin Feng and Li'er looked at each other and faced the enemy again without hesitation. Lin Feng used magic to control the elemental power around him, forming powerful attacks. Li'er concentrated her energy to provide magic support for Lin Feng.

In the battle with the python, Lin Feng gradually realized some new magic skills. He found that by concentrating the magic power on the sword, he could exert a stronger power. After a hard battle, they finally defeated the python.

However, the crisis was not resolved. They continued to move forward and came to an ancient cave. The cave was filled with a mysterious atmosphere, which made people feel inexplicably fearful.

Lin Feng walked into the cave carefully, and saw ancient runes engraved on the cave wall. He tried to decipher these runes, but found that they contained extremely complex fairy magic rules.

Just as he was lost in thought, a low roar suddenly came from the cave. A huge monster slowly walked out of the darkness. The monster was as big as a mountain and exuded a powerful pressure.

Lin Feng and Li'er felt unprecedented pressure, but they did not back down. Lin Feng took a deep breath, adjusted his state, and once again used a powerful magic. Li'er also assisted with all her strength, injecting her own magic power into Lin Feng's attack.

In the fierce battle, Lin Feng suddenly had an idea, and he remembered a secret of immortality that the old man had taught him. He quickly mobilized his immortal power according to the method in the secret, and saw a layer of golden light around his body, which turned into countless sharp blades and flew towards the monster.

Under this powerful attack, the monster gradually couldn't hold on and finally fell to the ground.

After this battle, Lin Feng and Li Er's immortal skills have been greatly improved. They continue to explore the immortal way, constantly facing various challenges and dangers.

By chance, they discovered an ancient secret book of immortal arts, which recorded a powerful method of cultivating immortal arts. Lin Feng and Li'er decided to practice according to the method in the secret book.

The process of cultivation was full of hardships and dangers. They needed to absorb the spiritual energy between heaven and earth at a specific time, and if they were not careful, they would go astray. But with firm belief and tenacious perseverance, they gradually mastered this powerful magic.

As their immortal skills continue to improve, Lin Feng and Li Er's status in the immortal world is gradually improving. However, they are not complacent because of this, but face future challenges more cautiously.
