Genshin Impact.

Lin Feng is a young warrior with a mysterious background. He has been practicing martial arts with a hermit master in the mountains since he was a child. He is gifted, hardworking and diligent, and has achieved a high level of accomplishment in martial arts at a young age.

One day, Lin Feng accidentally rescued a girl named Li'er in the forest. Li'er had lively eyes and a beautiful face, but her life was miserable. She had to flee because her family was destroyed by evil forces. Lin Feng felt pity for her and decided to protect Li'er and take her on the journey of the rivers and lakes.

During the journey, they met a strange old man. The old man was wearing a tattered robe, his hair was gray, but his eyes were deep and sharp. The old man saw that Lin Feng had a great foundation, and he secretly admired him and decided to teach him some more advanced martial arts secrets and martial arts experience.

Under the guidance of the old man, Lin Feng's martial arts improved by leaps and bounds, and Li'er also took good care of their daily lives. Although the three of them occasionally encountered some dangers, they were able to overcome them with the bravery of Lin Feng, the wisdom of the old man and Li'er's cleverness.

However, the peaceful days did not last long. One day, when they passed through a small town, they accidentally offended the local bullies. In order to retaliate, the bullies gathered a large number of masters and launched a crazy hunt against them.

Lin Feng and his two companions fled all the way to a barren desert. The desert was scorching hot and water was scarce, so they soon fell into a desperate situation. At this time, the old man, due to his advanced age and the long journey, gradually lost his strength and fell into a coma.

Lin Feng carried the old man on his back and pulled Li'er, moving forward with difficulty in the desert. Li'er's lips were chapped due to lack of water. Lin Feng looked at her with heartache and gave her the little water he had left.

"Brother Lin Feng, you need water too, otherwise you won't be able to hold on." Li'er said weakly.

"I'm fine. As long as I'm here, you and grandpa won't be harmed." Lin Feng said firmly.

After walking in the desert for several days, they finally found an abandoned ancient city. There was a gloomy atmosphere in the ancient city, but in order to find water and food, they decided to venture in.

After entering the ancient city, they found that it was full of traps and mechanisms. Lin Feng carefully protected the old man and Li'er, and with his superb martial arts, he resolved the crisis time and time again.

However, just when they thought they were about to find a source of water, a group of mysterious men in black suddenly appeared and surrounded them. The leader of the men in black was a stern-looking man who looked at Lin Feng with a hint of disdain in his eyes.

"Boy, today is the day you die." The leader in black said coldly.

Lin Feng protected the old man and Li'er behind him and clenched the sword in his hand. "If you want to hurt them, you have to step over my body first."

A fierce battle broke out instantly. Lin Feng fought alone against many enemies. Although he fought hard, he was outnumbered and gradually suffered multiple injuries. Li Er saw Lin Feng injured and was extremely worried. She rushed forward regardless of the danger and wanted to help Lin Feng.

"Lier, go back!" Lin Feng shouted loudly.

But Li Er did not retreat. She picked up a short sword on the ground and fought side by side with Lin Feng. The old man watched from the side, his heart full of emotion and worry.

Just as they were gradually running out of strength, the old man suddenly opened his eyes and burst out with a powerful internal force. The old man performed a set of mysterious martial arts moves and instantly repelled the surrounding black-clothed men.

"Grandpa!" Li'er shouted in surprise.

The old man looked at them and smiled, "Kids, I'm not going down that easily."

With the help of the old man, they finally repelled the men in black and found water and food. After a period of rest, their bodies gradually recovered.

However, they know that the danger is not over yet. The bully will not give up, and they must become stronger to protect themselves and those around them.

So, the three of them continued on their journey of cultivation. They searched for martial arts secrets everywhere, challenged various masters, and set off a bloody storm in the martial arts world.

As time went by, Lin Feng's martial arts had reached the pinnacle, Li'er had also become an outstanding warrior, and the old man's body had gradually recovered.

Finally, they faced the final showdown with the evil forces. In a fierce battle, Lin Feng, Li Er and the old man worked together to completely eradicate the evil forces and bring peace to the world.

From then on, Lin Feng, Li Er and the old man lived a peaceful and happy life. Their story became a legend in the martial arts world and was passed down by people forever.
