Genshin Impact.

Lin Feng's adventure in Teyvat has been going on for some time. After continuous efforts and experience, he has become more and more proficient in controlling the elemental power. With the help of the Knights of Favonius and various friends, his strength has been significantly improved.

One day, Lin Feng accidentally heard a rumor in the tavern of Mondstadt. It is said that in a distant place, there is a mysterious relic hidden in the mountains. This relic is said to be left by ancient gods. It is full of various dangers and opportunities, and there are countless precious treasures and powerful elemental forces waiting for people to discover.

Lin Feng was filled with curiosity and a desire to explore, so he decided to embark on a journey to find the mysterious ruins. After preparing the necessary supplies and equipment, he set out alone.

After several days of trekking, Lin Feng finally arrived at the mountain where the rumored mysterious ruins were located. The mountains here were high and densely forested, surrounded by clouds and mist, exuding a mysterious and dangerous atmosphere. Lin Feng carefully shuttled through the mountains and forests, relying on his keen perception of elemental power to find the entrance to the ruins.

Finally, he found some strange runes and patterns on the stone wall of a valley. Lin Feng used elemental power to activate these runes, and a door slowly appeared on the stone wall, with a strange light shining inside.

He took a deep breath and stepped into the ruins. As soon as he entered, the door closed behind him, and the surroundings fell into darkness. Lin Feng immediately became alert and released elemental power to illuminate the surroundings.

The interior of the ruins was filled with an ancient atmosphere, and the walls were engraved with various mysterious symbols and patterns, which seemed to tell stories from the past. Lin Feng walked slowly along the passage, carefully avoiding possible traps.

In a spacious hall, Lin Feng encountered a group of elemental creatures guarding the ruins. These creatures had powerful powers, they manipulated various elements and attacked Lin Feng.

Lin Feng was not afraid at all, he flexibly used the elemental power he mastered to fight back. Flames, water, wind and thunder and other elements intertwined in his hands, and he started a fierce battle with the elemental creatures.

After a hard fight, Lin Feng finally defeated these elemental creatures. He continued to go deeper into the ruins and found an ancient book in a secret room. The book recorded a powerful element fusion technique and some secrets about the ruins.

Lin Feng eagerly studied the contents of the book. He found that this element fusion technique could combine different elemental powers to form a more powerful attack method. He decided to try to practice this technique in the ruins.

During the practice, Lin Feng encountered some difficulties. The fusion of elements requires extremely high precision and control. A little carelessness may cause the elements to be unbalanced and cause danger. But he did not give up. With his firm will and constant attempts, he gradually mastered the essentials of element fusion.

When Lin Feng successfully combined multiple elements and released a powerful force, the entire ruins shook. He felt that his strength had made a qualitative leap, and his heart was filled with joy.

However, at this moment, a powerful dark force suddenly appeared in the ruins. This force quickly spread, making Lin Feng feel an unprecedented pressure.

In the darkness, a mysterious figure gradually emerged. It was a man with a dark aura all over his body, and his eyes were cold and evil.

"Who are you? Why are you here?" Lin Feng asked vigilantly.

The mysterious man sneered: "I am the guardian of this relic. How dare you, an uninvited guest, trespass here and try to gain the power here? I will not let you succeed!"

After that, the mysterious man launched an attack on Lin Feng. His attack contained the power of dark elements, strange and powerful.

Lin Feng responded with all his strength. He used his newly mastered element fusion skills to the extreme and started a thrilling duel with the mysterious man.

During the battle, Lin Feng discovered that the mysterious man's dark power seemed to echo with some kind of power in the ruins. He realized that only by finding and destroying the source of this power could he defeat the mysterious man.

So, while Lin Feng was dealing with the mysterious man, he carefully observed the environment in the ruins. Finally, he found a dark rune array hidden in the corner.

Lin Feng rushed towards the rune array with all his strength, trying to destroy it. The mysterious man noticed his intention and frantically tried to stop him.

At the critical moment, Lin Feng burst out with powerful strength, broke through the mysterious man's defense, and successfully destroyed the dark rune array.

As the rune array was destroyed, the mysterious man's power weakened dramatically. Lin Feng took the opportunity to launch a final attack and completely defeated the mysterious man.

After the battle, the dark power in the ruins gradually dissipated. Lin Feng breathed a sigh of relief and began to carefully explore other parts of the ruins.

Deep in the ruins, he found a mysterious treasure chest, which was inlaid with various precious gems and emitted a mysterious light.

Lin Feng carefully opened the treasure chest, and inside was a divine weapon that exuded powerful elemental power. He picked up the artifact and felt a powerful force surge in his heart.

At this time, the ruins began to shake violently and seemed to be about to collapse. Lin Feng knew that it was not suitable to stay here for long, so he quickly left the ruins with the artifact.

When he walked out of the ruins, the sunlight outside was particularly dazzling. Lin Feng looked back and saw that the mysterious ruins gradually disappeared behind him.

This adventure brought Lin Feng a lot of gains. He not only mastered the powerful element fusion technique, but also obtained a magic weapon. He knew that these would become his precious wealth in the future immortal journey.

Lin Feng set out on his journey home, full of expectations for the future. He knew that there were more challenges and secrets waiting for him to explore on the continent of Teyvat...
