Genshin Impact.

Lin Feng walked slowly in a barren desert. The scorching sun burned his skin mercilessly. With every step he took, the sand under his feet seemed to swallow him up. His clothes were tattered, but his eyes revealed a determined light.

Next to him was the mysterious old man, with white hair and wrinkles on his face like the ravines of time, but his eyes sparkled with wisdom and depth, as if he knew all the secrets of the world.

"Lin Feng, this journey of life and death is a turning point in your destiny. Whether you can grasp it depends entirely on yourself." The old man's voice was hoarse and low.

Lin Feng gritted his teeth and nodded, "Senior, I will definitely do my best."

Suddenly, a gust of wind whistled past, blowing up dust all over the sky. Lin Feng subconsciously covered his eyes with his hands. When the wind and sand passed, an ancient castle appeared in front of them. The walls of the castle were mottled and exuded a decayed smell.

"This is..." Lin Feng looked at the old man in confusion.

The old man smiled and said, "This is our destination."

The two entered the castle, which was dark and damp, with a strange atmosphere. The torches on the wall flickered with a faint light, reflecting the gloomy scene around them.

"Help!" Lin Feng's heart tightened when he heard a cry for help, and he ran in the direction of the sound. In a dark room, he saw a girl tied to a stone pillar. It was Li'er.

"Li'er!" Lin Feng exclaimed and rushed forward to untie the ropes on Li'er.

At this moment, a group of black shadows came from all directions and surrounded them. Lin Feng drew his sword and started a fierce battle with the black shadows. The old man stood aside, forming seals with his hands and casting powerful spells to help Lin Feng.

After a fierce battle, the shadow gradually dissipated and Lin Feng successfully rescued Li'er.

"Brother Lin Feng, I'm so scared." Li'er threw herself into Lin Feng's arms, her tears soaking his clothes.

Lin Feng gently patted Li'er's back, "Don't be afraid, I'm here."

However, before they could catch their breath, a low roar came from deep inside the castle. The old man's face changed, "Oh no, the owner of the castle has woken up."

The three of them walked cautiously towards the depths of the castle. In a huge hall, they saw a huge monster. The monster was as big as a mountain, with sharp claws and fangs, and its eyes flashed blood-red light.

"What kind of monster is this?" Lin Feng took a breath of cold air.

The old man looked solemn, "This is an ancient demon beast. It is very powerful. We must be careful when dealing with it."

When the monster saw them, it opened its bloody mouth and spewed out a stream of black flames. Lin Feng dodged sideways and swung the sword in his hand, slashing a stream of sword energy at the monster. The monster raised its claws and easily blocked the sword energy.

The old man waved his hands, and runes flew out from his hands and flew towards the monster. The monster was hit by the runes and let out a painful roar.

Lin Feng took the opportunity to launch an attack, and cooperated with the old man to fight a desperate battle with the monster. After a fierce battle, the monster gradually lost the upper hand. Just when they thought they were about to win, the monster suddenly performed a powerful forbidden technique, and the whole castle began to shake violently.

"Oh no, the castle is going to collapse!" Amber exclaimed.

Lin Feng grabbed Li'er and Amber and rushed out of the castle. Behind them, the castle collapsed with a loud bang, raising a cloud of dust.

"Cough cough..." Lin Feng crawled out of the dust and looked at the ruins in front of him, feeling a little scared.

"Thanks to you this time, otherwise I would not be able to defeat this monster." The old man said with emotion.

Lin Feng smiled slightly, "Senior, this is our joint effort."

However, what they didn't know was that a bigger crisis was quietly approaching...

After leaving the castle, they continued their journey of life and death. Along the way, they encountered various difficulties and obstacles, but they overcame them one by one with their tenacious will and courage.

One day, they came to a mysterious valley. The valley was filled with thick fog and was silent, giving people a gloomy and terrifying feeling.

"Everyone be careful, there is something strange here." The old man warned.

Lin Feng held his sword tightly and walked in front carefully. Suddenly, a melodious flute sound came, the sound was like crying and complaining, as if telling a sad story.

"This flute sound..." Li'er's face turned pale.

Lin Feng walked in the direction of the flute sound and saw a woman in white sitting under a big tree, holding a flute in her hand. The woman had long hair and a beautiful face, but her eyes revealed a hint of sadness.

"Who are you?" Lin Feng asked vigilantly.

The woman raised her head and looked at Lin Feng, "I have been waiting for you for a long time."

The old man stepped forward and asked, "Girl, what is your purpose?"

The woman smiled slightly, "My goal is to take your lives."

After that, the woman waved the flute in her hand, and a powerful force attacked them. Lin Feng waved his sword to resist, but the force was too strong and he was knocked back a few steps.

Upon seeing this, the old man formed seals with his hands and cast a powerful barrier that enveloped them.

“Hmph, you think you can stop me with just this barrier?” The woman sneered and swung the flute in her hand again. An even more powerful force attacked the barrier.

Cracks began to appear in the barrier, and the old man's face turned solemn.

"Lin Feng, we must join forces to have a chance to defeat her." said the old man.

Lin Feng nodded and launched an attack together with the old man. Li'er and Amber also came to support them.

With their joint efforts, the woman gradually lost the upper hand. But she did not give up, but performed a forbidden technique, burning her own vitality in exchange for powerful strength.

"Oh no, she's going to fight to the death!" the old man exclaimed.

Lin Feng gritted his teeth and said, "No matter what, we can't let her succeed."

A thrilling battle started again. In the end, they succeeded in defeating the woman. She fell to the ground and disappeared into a puff of smoke.

"It's finally over..." Lin Feng breathed a sigh of relief.

However, their crisis is not over. In the depths of the valley, a more evil force is awakening...

They continued to move forward, and the fog became thicker as they went deeper into the valley. Suddenly, a dark shadow flashed past them from behind.

"Who?" Lin Feng turned around and shouted.

But there was no response from anywhere.

"Everyone be careful, something's happening." The old man looked around vigilantly.

At this moment, countless black shadows rushed in from all directions and surrounded them. These black shadows were like ghosts, and their speed was extremely fast, making it difficult to defend against them.

Lin Feng swung his sword and started a fierce battle with the black shadows. However, the number of black shadows increased, and they gradually fell into trouble.

"This is not a solution," Amber said.

Li Er suddenly had an idea, "I have a way."

After that, Li'er took out a bright pearl from her bosom. The bright pearl was shining brightly. Li'er threw the bright pearl into the air, and the bright pearl turned into a ray of light, illuminating the entire valley.

Under the illumination of the light, the shadows had nowhere to hide. Lin Feng and others took the opportunity to launch an attack and eliminated the shadows one by one.

After a fierce battle, they finally got rid of the shadows, but they also consumed a lot of physical strength and magic power.

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

They quickened their pace and finally walked out of the valley. But what they didn't know was that behind them, a pair of eyes were watching their every move...

After leaving the valley, they came to a small town. The people in the town looked panicked, as if something terrible had happened.

"Excuse me, what happened here?" Lin Feng stopped a passerby and asked.

The passerby looked at them and said, "Recently, a group of robbers came to town, burning, killing, looting, and committing all kinds of evil."

Lin Feng frowned, "Where are these bandits now?"

The passerby pointed to a mountain village outside the town and said, "They are right there."

Lin Feng decided to get rid of the evil for the people. He walked towards the village with the old man, Li'er and Amber.

At the entrance of the mountain stronghold, a group of bandits were standing guard. When they saw Lin Feng and the others, they rushed over waving their weapons.

Lin Feng and others were not afraid and started a fierce battle with the robbers. After a fierce battle, they successfully eliminated all the robbers and rescued the people of the town.

The people in the town were so grateful to them that they took out food and wine from their homes to entertain them.

After resting for a night in the town, they continued on their journey. However, what they didn't know was that a bigger conspiracy was waiting for them...
