Genshin Impact.

After Lin Feng and others found strange runes in the mysterious ruins, they fell into deep thought. The mysterious runes seemed to contain some powerful power and secrets, but they were still puzzling.

The old man stared at the runes, his eyes sparkling with wisdom. He stroked his chin gently and said slowly: "These runes are definitely not ordinary things. Their appearance may mean that we are about to uncover a shocking secret."

Lin Feng nodded, his eyes never leaving the runes: "But how do we interpret these runes? They seem to have no pattern to them."

Amber frowned and said after thinking for a moment, "Perhaps we can start from other clues in the ruins and find some clues related to these runes."

Li'er also agreed: "Yes, let's look around."

So, everyone began to search carefully in the ruins. However, after some efforts, they did not find any valuable clues.

Just when everyone was feeling frustrated, Lin Feng suddenly discovered that when his sword approached those runes, a faint light actually flashed on the sword.

"Look!" Lin Feng exclaimed.

Seeing this, the old man's eyes flashed with surprise: "It seems that there is some connection between your sword and these runes."

Lin Feng held the sword in his hand and approached the rune carefully. As the distance between the sword and the rune got closer and closer, the light on the sword became stronger and stronger. Suddenly, the sword seemed to be attracted by some powerful force and flew towards the rune, sticking tightly to the rune.

Then, something strange happened. A dazzling light burst out from the rune, illuminating the entire space like daylight. In the light, blurry images began to emerge.

Everyone looked closely and saw an ancient castle appear on the screen, surrounded by a powerful magic barrier. Inside the castle, there was a huge book, and on the cover of the book, there were runes exactly the same as the ones in front of them.

"It seems that the key to deciphering these runes may be hidden in that castle." The old man said thoughtfully.

"But how do we find this castle?" Amber asked.

Lin Feng pondered for a moment and said, "Since these images are triggered by runes, perhaps the runes can guide us."

After that, Lin Feng took the sword off the rune again. The tip of the sword pointed in a direction, and everyone looked in that direction, only to see a deep passage ahead.

"It seems that we can only walk along this passage and see if we can find the castle." Li'er said.

Without hesitation, they walked slowly along the passage. A mysterious atmosphere filled the passage, and strange lights flickered on the walls. After walking for a while, they came to a huge stone door.

The stone door was tightly closed, and it was covered with complex runes. Lin Feng tried to touch the runes with his sword, but this time, the sword did not react at all.

"The runes on this stone gate seem to be different from the runes we have seen before." said the old man.

Just when everyone was at a loss, Amber suddenly discovered that there was a depression on the wall next to the stone gate, and its shape was very similar to a sword.

Lin Feng inserted his sword into the depression, and with a "click" sound, the stone door slowly opened. A powerful force surged out from the door, sucking everyone in.

When they opened their eyes again, they found themselves in an unfamiliar space. Surrounded by a vast starry sky, countless stars were shining brightly. In front of them, a magnificent castle was suspended in the starry sky. It was the castle they saw in the picture.

Everyone walked towards the castle cautiously. The castle gate was closed tightly, and runes were also engraved on the door. Lin Feng touched the runes with his sword again, and the gate slowly opened.

After entering the castle, they saw the huge book. The book lay quietly on an ancient table, exuding a mysterious atmosphere. Lin Feng walked forward and gently opened the book.

The pages of the book were densely engraved with runes and words. The old man studied the runes and words carefully, and a look of surprise gradually appeared on his face.

“I understand now. These runes are an ancient magical language. They record a powerful magic spell.” The old man said excitedly.

"So what does this magic spell do?" Amber asked.

The old man took a deep breath and said slowly: "This magic spell can open the door to another world. In that world, there are endless treasures and powerful powers."

Everyone was excited and nervous after hearing this. However, they didn't know that a huge crisis was quietly approaching while they were interpreting the runes...

Just as they were immersed in the joy of discovering the magic spell, the castle suddenly shook violently. A black light emerged from the depths of the castle and turned into a huge black shadow.

The shadow let out a sinister laugh: "You ignorant humans, how dare you touch this forbidden rune? Today, you will all die here!"

Lin Feng and everyone else immediately became alert, drew their weapons, and prepared to fight.

Lin Feng rushed towards the shadow first, the sword in his hand flashing coldly. The shadow waved his arm lightly, and a powerful force pushed Lin Feng back.

Upon seeing this, the old man muttered something and cast a powerful magic shield that enveloped everyone.
