Genshin Impact.

After the dangerous battle, Lin Feng collapsed to the ground exhausted, gasping for breath. The old man, Amber and Li'er quickly surrounded him.

"Lin Feng, are you okay?" Li'er's eyes were full of worry, and she stretched out her hand to help Lin Feng up.

Lin Feng waved his hand, indicating that he was fine, but just needed a short rest. The old man looked around and said solemnly: "It is not advisable to stay here for long. The fighting just now was too noisy, and I am afraid it will cause more trouble."

Everyone nodded in agreement, and after adjusting their status a little, they stood up and continued on their way. They traveled through the mountains and forests for several days, and did not encounter any major dangers along the way.

Until one day, they came to a mysterious ruins. The ruins were shrouded in a layer of light mist, and the ancient buildings were covered with vines, exuding a vicissitudes and mysterious atmosphere.

Lin Feng looked at the ruins in front of him, and an inexplicable impulse surged in his heart: "Maybe there is some opportunity hidden in it." The old man thought for a moment, nodded and said: "Since we are here, we should make the best of it. But everyone must be careful."

Everyone stepped into the ruins carefully. As soon as they entered, they felt a strong pressure coming towards them. Strange runes flashed on the walls around them, as if telling an ancient story.

They walked slowly along the passage, hearing low roars from time to time. Amber tightened her grip on the weapon and looked around vigilantly. Suddenly, a huge beast jumped out from the side room.

Lin Feng reacted quickly and dodged the attack. Looking closely, he saw that it was a huge two-headed lion beast, its eyes flashing scarlet light and blazing flames spewing from its mouth.

The old man shouted loudly, waved his staff, and a beam of ice-blue light shot towards the two-headed lion beast. The two-headed lion beast was hit by the light and paused. Lin Feng took the opportunity to rush forward, and the long sword in his hand flashed with cold light, stabbing towards the neck of the two-headed lion beast.

Li Er was not to be outdone, and formed seals with her hands, sending beams of magic light towards the two-headed lion beast. With everyone's concerted efforts, the two-headed lion beast gradually lost and finally fell to the ground.

After dealing with the two-headed lion beast, they continued to go deeper into the ruins. Deep inside the ruins, they found an ancient altar. On the altar, there was an ancient book emitting a faint glow.

Lin Feng stepped forward and was about to pick up the ancient book, but was bounced away by a powerful force. The old man stepped forward, observed it carefully, and said, "There is a powerful restriction on it, so don't act rashly."

Just as they were thinking about how to break the ban, a violent tremor suddenly came from the ruins. The surrounding walls began to collapse, and countless boulders rolled down.

"Oh no, this place is going to collapse!" Amber exclaimed.

Everyone hurriedly looked for a way out, but the retreat was blocked by the collapsed boulders. Just when they were in a desperate situation, Lin Feng suddenly found a secret door next to the altar.

"Everyone, follow me!" Lin Feng shouted.

Everyone followed Lin Feng into the secret door, behind which was a narrow passage. They moved forward quickly in the passage, and the sound of collapse continued to come from behind them.

After running for an unknown amount of time, they finally walked out of the passage and came to an unfamiliar valley. The valley was filled with thick fog, making it difficult to tell the direction.

"What should we do now?" Li'er asked.

Lin Feng looked around, thought for a moment and said, "Let's first look for other ways out of this valley, and explore this place. Maybe there are some secrets hidden here."

Everyone nodded in agreement and began to explore the valley. Deep in the valley, they found an ancient cave. At the entrance of the cave, there were some strange runes engraved.

The old man studied the rune and said, "This seems to be a sealing rune. It seems that there is something important in this cave."

Lin Feng pushed open the door of the cave with force, and a stale smell came in. They walked into the cave and saw some bottles and jars and a few magic weapons placed inside.

Lin Feng picked up a magic weapon and observed it carefully, and found that it was a powerful attack magic weapon. Just as they were about to study these things carefully, a sinister laugh suddenly came from the cave.

"Who is it?" Amber asked warily.

"Haha, you ignorant youngsters, how dare you trespass into my territory." A dark shadow slowly walked out from the darkness.

When everyone looked closely, they saw that the black shadow was a man with a ferocious face, emitting a powerful aura.

"Who are you?" Lin Feng asked.

"I am the owner of this cave. If you break into my place, don't even think about getting out alive." The man sneered.

A fierce battle is about to begin. Can Lin Feng and his team defeat this mysterious man and escape from this predicament? Everything is still unknown...
