Genshin Impact.

Lin Feng, Amber, Li'er and the mysterious old man went further and further on the road of exploring the mystery of the runes. The many questions left in the previous chapter were like a fog covering their hearts.

After many days of research and discussion, they have gained some understanding of the mysterious runes. However, this progress is far from enough, and the secrets hidden behind the runes are still unfathomable.

On this day, the sun shone through the dense leaves into the small house where they were staying temporarily. Lin Feng looked at the rune patterns copied on the wall and fell into deep thought. The old man sat on a wooden chair beside him, gently stroking an ancient jade pendant in his hand, with a thoughtful look in his eyes.

"Senior, I always feel that there is a pattern in the arrangement of these runes, but I just can't grasp the key." Lin Feng broke the silence in the room.

The old man raised his head slightly, shifted his gaze from the jade pendant to Lin Feng, and said slowly: "The power of these runes is by no means as simple as we currently understand. They seem to be connected to some powerful source of power, but where that source is is still unknown."

Amber crossed her arms and leaned against the wall. "So what should we do next? We can't just sit here and do nothing."

Li'er walked gently to Lin Feng's side, "Brother Lin, why don't we go to the place where we found the rune and have a look, maybe we can find something new."

Lin Feng nodded, "This is the only way. Perhaps returning to the original place will help us find some missing clues."

After everyone reached a consensus, they simply packed their bags and set off on the journey to the place where the runes were discovered. Along the way, a thin layer of fog filled the mountains and forests, adding a mysterious atmosphere to their journey.

After arriving at the destination, Lin Feng looked around. Everything here was still so familiar and strange. The runes on the stone wall still emitted a faint light, as if telling an ancient story.

Amber moved closer to the stone wall and observed the runes carefully. "Why do I feel that the light of these runes is a little dimmer than when we came here last time?"

Hearing this, Lin Feng also stepped forward and looked at it carefully. "Indeed, is it possible that the power of these runes is gradually weakening?"

The old man stroked his beard, thinking, "Maybe this has something to do with our research on them, or maybe there are some external factors affecting them."

At this moment, Lin Feng suddenly discovered a tiny crack in the corner of the stone wall. He had not noticed it before because he had focused on the runes. He squatted down and gently touched the crack with his hand, only to feel a weak force coming from the crack.

"Everyone come and look, there is a crack here." Lin Feng called to everyone.

The old man, Amber, and Li'er all gathered around. The old man looked at the crack and his expression became serious. "There seems to be something hidden in this crack."

Lin Feng took out a knife from his bag and carefully dug along the edge of the crack. As the soil and gravel fell off, a small cave gradually appeared in front of them. There was a little light flickering in the cave, and a closer look revealed that it was a rune stone that exuded an ancient atmosphere.

Amber opened her mouth in surprise, "What is this? Is it something related to these runes?"

Lin Feng picked up the rune stone and carefully felt the power fluctuations on it. "This rune stone contains powerful power. It may be the key to solving the mystery of the rune."

The old man took the rune stone and examined it carefully for a moment. "This rune stone is very old, and the runes on it seem to have the same origin as the runes on the stone wall. We have to study it carefully."

After returning to the cabin, everyone began to study the rune stone in depth. However, no matter how they tried, they could not decipher the secret of the rune stone.

Just when they were in trouble, Li'er suddenly remembered an ancient book. "I remember seeing an ancient book about ancient runes in the family library. Maybe there will be relevant records in it."

Lin Feng's eyes lit up, "Then what are we waiting for? Let's go and get that ancient book."

After a lot of running around, they came to Li'er's family. In the library, after some searching, they finally found the ancient book. The paper of the ancient book had turned yellow, and it recorded some legends about ancient runes and how to interpret them.

They were overjoyed and returned to the cabin with the ancient book, and began to study the rune stone with the ancient book. After several days of hard work, they finally found some clues on the rune stone. It turned out that the rune stone was the key to open an ancient ruin, and the ruins hid the ultimate secret of the power of runes.

After hearing the news, everyone was excited and nervous. They knew that what awaited them was an adventure full of challenges and unknowns. But in order to solve the mystery of the runes, they resolutely set out on the road to the ruins.

Along the way, they encountered various dangers, including ferocious beasts and complex traps, but they relied on their mutual trust and courage to overcome dangers time and time again.

Finally, they arrived at the entrance of the ruins. The ancient stone door was tightly closed, and the door was engraved with runes. Lin Feng took out the rune stone and gently inserted it into the groove on the stone door. After a dull sound, the stone door slowly opened, and a powerful force rushed towards him.

They walked into the ruins, which were filled with a mysterious atmosphere. Strange lights flickered on the walls, and complex rune patterns were engraved on the ground. Deep in the ruins, there was a huge stone platform, on which was placed a book emitting golden light.

Lin Feng walked forward and gently picked up the scroll. The words on the scroll were ancient and mysterious. They took a lot of effort to decipher the contents. It turned out that these runes were left by powerful people in ancient times, and contained the secret of controlling the power of heaven and earth. But this power was too strong. If it was obtained by someone with evil intentions, it would bring disaster to the world.

After learning the truth, Lin Feng and others knew that they had a great responsibility. They decided to protect these secrets and prevent the power of the rune from falling into the hands of bad people. However, their actions had already been noticed by a dark force. When they left the ruins, the killer of the dark force quietly attacked.

A fierce battle began. Lin Feng, Amber, Li'er and the old man worked closely together to fight the killers. During the battle, Lin Feng gradually realized the power of runes and his strength increased greatly. He cast powerful rune spells and defeated the enemies one by one.

After this battle, they are more determined to protect the secret of the rune. They know that the road ahead is still long and there will be more challenges waiting for them, but they are fearless because they have a firm belief and mission to protect the world in their hearts.
