Genshin Impact.

Lin Feng looked at the deep valley in front of him, and an inexplicable tension surged in his heart. The old man beside him had a solemn expression, and a hint of worry in his eyes.

"Lin Feng, this time we are going deep into the tiger's den, which is full of dangers. Are you ready?" The old man's voice was hoarse and steady.

Lin Feng tightened the hilt of the sword in his hand and looked at the old man with a firm gaze, "Senior, I am ready. In order to save the people of the world, I will not hesitate even if it means going through mountains of swords and seas of fire."

The old man nodded slightly, with a hint of approval in his eyes, "Okay, let's go."

The destination of their trip is a magic cave deep in the valley. According to legend, it is the lair of evil forces, ruled by a powerful demon. These evil forces have been doing evil in the world in recent years and have killed countless innocent people. As a righteous knight, Lin Feng decided to go deep into the tiger's den with the old man to eradicate the evil after learning about this.

Along the way, Lin Feng carefully observed the movements around him. A thin layer of mist filled the valley, making the surrounding scenery look a little hazy. Suddenly, a gust of cold wind blew, and Lin Feng couldn't help but shiver.

"Be careful!" the old man shouted in a low voice.

A group of black shadows rushed out from all directions and surrounded them. These black shadows were the minions in the demon cave, all of them had hideous faces and held weapons.

Lin Feng was not afraid at all, and he raised his sword to meet the enemy. His sword skills were sharp, and each of his swords contained a strong internal force. In an instant, several minions fell under his sword. The old man was not to be outdone, and he used his unique skills. He waved his hands, and a strong energy gushed out, shaking the minions around him away.

After a fierce battle, they finally defeated the minions and continued to move forward to the magic cave. Soon, they came to the entrance of the magic cave. There stood two huge stone statues at the entrance, and their eyes flashed with strange light.

Lin Feng took a deep breath and walked into the magic cave with the old man. The interior of the magic cave was dark and damp, filled with a pungent smell of blood. There were some human skin lanterns hanging on the wall, which made people feel creepy.

They walked forward cautiously, and suddenly, a sinister laugh came from the front. "Haha, you are finally here."

Lin Feng looked carefully and saw a man in a black robe appear in front of them. The man was wearing a mask and his face could not be seen clearly.

"Are you the devil here?" Lin Feng glared at the man.

The man sneered, "Yes, I am the person you are looking for. Since you are here today, don't even think about leaving alive."

After saying that, the man raised his hand and waved it, and a powerful magic power attacked Lin Feng and the others. Lin Feng and the old man quickly used their power to resist, and the two sides started a fierce contest.

In the fierce battle, Lin Feng gradually discovered that the demon's strength was far superior to theirs. They gradually fell into trouble and suffered a lot of injuries.

Just when they were about to collapse, a figure suddenly appeared. It turned out to be Amber, who had been secretly watching Lin Feng and his men's actions. When she saw that they were in danger, she rushed to help them in time.

Amber used her special skills, and rays of light shot out from her hands, attacking the demon. The demon was a little flustered for a moment, and Lin Feng and his men took the opportunity to launch a counterattack.

With the concerted efforts of the three, the demon gradually lost the upper hand. Finally, Lin Feng saw the right moment and stabbed the demon's vital point with a sword. The demon screamed, fell to the ground, and disappeared into a cloud of smoke.

They successfully eradicated the demon and saved the people of the world. However, in the battle, the old man was unfortunately seriously injured.

"Lin Feng, I'm afraid I can't make it." The old man said weakly.

"Senior, don't say that. You will be fine." Lin Feng's eyes were red.

The old man smiled slightly, "Lin Feng, don't be sad. I have no regrets in my life for being able to eradicate evil with you. The future of the martial arts world depends on you."

After saying this, the old man slowly closed his eyes. Lin Feng was heartbroken, and he secretly vowed to inherit the old man's will and protect this world.

Amber walked to Lin Feng and patted his shoulder gently, "Lin Feng, don't be too sad, we still have to move on."

Lin Feng nodded and wiped away the tears from his eyes, "Well, let's go."

They walked out of the devil's cave, and the sun was shining brightly outside. Lin Feng looked at the sky, feeling a lot of emotions in his heart. After this life-and-death battle, he understood that the power of justice is infinite, and as long as there is faith in one's heart, there is no difficulty that cannot be overcome.

Soon, Lin Feng became famous in the martial arts world and became a great hero. Together with Amber, he continued to protect the peace and tranquility of the martial arts world.

In a remote town, a girl named Li'er was selling flowers on the street. She heard about Lin Feng's deeds and was filled with admiration. She secretly decided that one day she must meet this hero.
