Genshin Impact.

Lin Feng, Li'er and the old man carefully explored the ruins. The surroundings were filled with an ancient and mysterious atmosphere, and strange runes flickered on the walls.

"Be careful, this place may seem peaceful, but it actually hides secrets." The old man warned in a low voice.

Lin Feng nodded, holding his sword tightly in his hand, and looking around vigilantly. Li'er followed closely behind them, revealing a hint of nervousness in her lively eyes.

They walked slowly along the deep passage, the stone slabs under their feet made a slight "creaking" sound. Suddenly, a cold wind blew, and Lin Feng couldn't help but shiver.

"This wind comes strangely." Lin Feng said with a frown.

At this moment, a light curtain suddenly rose from the ground in front of them, blocking their way. Runes flowed on the light curtain, emitting powerful power fluctuations.

The old man walked forward and carefully observed the runes on the light curtain. After pondering for a moment, he said, "This seems to be a seal. We need to find a way to break it before we can pass."

Lin Feng and Li'er also came forward and began to study these runes. After some effort, they found that the arrangement of the runes seemed to follow a certain pattern.

Lin Feng closed his eyes and carefully felt the energy flow between the runes. Suddenly, a flash of inspiration came to his mind, "I understand, these runes need to be activated in a specific order to break the seal."

After that, Lin Feng began to activate the runes one by one according to what he thought in his mind. As the last rune was activated, the light curtain gradually dissipated, revealing a new passage.

The three of them continued to move forward, and soon they came to a spacious stone chamber. In the center of the chamber was a stone platform, on which was placed an ancient scroll.

Lin Feng walked forward and gently picked up the scroll, only to see that it was covered with densely packed words and patterns.

"Is this some kind of cultivation method?" Li'er asked curiously.

The old man carefully examined the scroll for a while, and said solemnly: "This is an ancient inheritance. If we can understand the mysteries in it, it will be of great benefit to our practice."

After hearing this, Lin Feng immediately began to study the book carefully. However, the content of the book was obscure and difficult for him to understand for a while.

At this moment, the scroll suddenly burst into a ray of light, enveloping Lin Feng. Lin Feng only felt a powerful force surging into his body, and all kinds of wonderful scenes kept emerging in his mind.

Li'er and the old man watched anxiously from the side, but did not dare to step forward and interrupt.

After a long while, the light gradually dissipated, and Lin Feng slowly opened his eyes. His eyes flashed with excitement, "I seem to have realized something."

Lin Feng shared his understanding with the old man and Li'er, and the three began to practice according to the contents of the book. In the process of practice, they constantly broke through their own bottlenecks and their strength was greatly improved.

However, their actions triggered the protective formation in the ruins. Countless rays of light suddenly shot out from the surrounding walls and attacked them.

"Be careful!" the old man shouted, and waved the whisk in his hand, which turned into a barrier to block in front of him.

Lin Feng and Li Er also used their unique skills to fight against the light. For a moment, the stone chamber was filled with light and energy fluctuations.

After a fierce battle, they finally succeeded in breaking the protective formation.

"It's not advisable to stay here for long, let's leave as soon as possible." said the old man.

The three of them left the stone chamber with the scroll and continued to explore the ruins. In the following journey, they encountered many challenges and opportunities.

They discovered a rare magical herb in a mysterious cave, which could enhance spiritual power after taking it; in an underground river, they found a powerful magic weapon.

As time went by, Lin Feng, Li'er and the old man gained more and more in the ruins, and their strength became stronger and stronger. However, they also knew that there were many unknown dangers hidden in the ruins, and they had to stay vigilant at all times.

In the process of exploring the ruins, they also met a cultivator who was also training in the ruins. This cultivator was named Bai Yu, who was generous and hit it off with Lin Feng and others at first sight.

"Meeting is fate, why don't we travel together and explore these ruins together." Bai Yu said with a smile.

Lin Feng and others readily agreed. With Bai Yu's joining, their team became even stronger.

Led by Bai Yu, they came to the depths of the ruins, where there was a huge palace with a closed door and mysterious patterns engraved on it.

"As far as I know, the core secret of the ruins is hidden in this palace." Bai Yu said.

Lin Feng and the others looked at each other and decided to push open the palace door to find out. The moment they pushed open the door, a strong breath rushed over. The palace was filled with various precious treasures and cultivation resources, but it also hid countless traps and dangers.

They walked into the palace carefully, taking every step with extreme caution. Deep in the palace, they found a huge stone tablet with an ancient text engraved on it.

The old man carefully studied the words on the stone tablet, his face gradually becoming solemn, "It turns out that this relic is a place of inheritance left by an ancient immortal. Only by passing many tests can you obtain the true inheritance."

After hearing this, Lin Feng and the others were inspired to fight. They decided to take on the challenge and obtain the inheritance.

In the following days, they went through one test after another in the palace. Some tests tested their wisdom, some tested their strength, and some tested their state of mind.

In the process of the test, they supported each other and made progress together. Finally, they successfully passed all the tests and obtained the inheritance of the ancient immortals.

After receiving the inheritance, Lin Feng and the others' strength made a qualitative leap. They decided to leave the ruins and return to the Immortal Gate. At the exit of the ruins, they looked back, their hearts filled with emotion.

This exploration of the ruins not only allowed them to gain powerful strength and precious treasures, but also allowed them to make like-minded friends and gain deep friendships.
