Genshin Impact.

After defeating the wizard and bringing light to the town, Lin Feng and Li'er took a short rest before embarking on their immortal journey again.

They walked through mountains, rivers and lakes, and saw many wonderful sights in the world. One day, they came to a place called "Spiritual Wind Valley". The spiritual energy here is rich, but it also hides unknown dangers.

As soon as he entered the valley, Lin Feng felt a mysterious force pulling him. Li'er also said solemnly: "Brother Lin Feng, I think this place is not simple."

At this moment, a gust of wind whistled past, and there seemed to be a strange sound in the wind. The old man's voice sounded in Lin Feng's mind: "Be careful, this wind is unusual."

Lin Feng and Li'er stood back to back, watching their surroundings vigilantly. Suddenly, a group of ghostly black shadows emerged from the wind and rushed towards them. Lin Feng waved his sword to meet the enemy, while Li'er cast a spell to help him.

After a fierce battle, the shadows gradually dissipated. But before they could catch their breath, the ground began to shake violently, and a huge ground beast emerged from the ground.

This ground beast was huge, with thick skin and flesh, and Lin Feng's attacks seemed to have little effect on it. Li'er shouted anxiously: "Brother Lin Feng, this is not a solution!"

Lin Feng dodged the attacks of the ground beast while thinking about countermeasures. Suddenly, an idea flashed in his mind and he said to Li'er, "Li'er, you use magic to restrain it, and I will find its weakness."

Li Er nodded and cast a spell with all her strength, beams of light shot towards the ground beast. Lin Feng took the opportunity to jump onto the back of the ground beast and observed it carefully. Finally, he found a piece of lighter scale on the back of the ground beast's neck, which must be its weakness.

Lin Feng gathered his strength and stabbed the scale with his sword. The ground beast roared in pain and collapsed to the ground.

After dealing with the ground beast, they continued on their way. The scenery in the valley became more and more bizarre, with colorful flowers blooming with strange light and mysterious runes flashing in the clear stream.

Lin Feng was curious and wanted to get closer to the stream to check it out. The old man's voice sounded again: "Don't act rashly. This stream contains powerful forces. If you are not careful, you will be sucked into it."

Lin Feng quickly retracted his steps. At this moment, a mysterious figure appeared in front of them. This figure was shrouded in a layer of light, and his face could not be seen clearly.

"Why did you break in here?" asked the mysterious figure.

Lin Feng stepped forward, cupped his hands and said, "We are people who have come down to earth to experience tribulations. We have no intention of offending you. It's just that this Spiritual Wind Valley seems to be related to our immortal path."

The mysterious figure was silent for a moment, then said: "In that case, you must pass my test before you can move on."

After that, the mysterious figure waved his sleeves, and a powerful barrier enveloped them. Within the barrier, countless illusions emerged, including their deepest fears and irresistible temptations.

Lin Feng and Li'er encouraged each other and broke through the illusions one by one with their firm will.

The mysterious figure nodded with satisfaction and removed the barrier: "You have passed the test, continue on. But remember, the immortal road is long and full of dangers, so don't take it lightly."

Lin Feng and Li'er thanked the mysterious figure and continued walking deeper into the valley.

As they walked, they came to an ancient temple. The door of the temple was closed, but a strong wave of immortal power came from inside.

Li'er said: "Brother Lin Feng, there may be some treasure hidden in this temple."

Lin Feng hesitated for a moment, but finally decided to push the door open. As soon as the door opened, a golden light shot out, blinding them.

When the light faded, they saw a mysterious sword enshrined in the center of the temple. The sword exuded a powerful aura, as if calling them.

Lin Feng walked forward and wanted to pick up the sword. Just as his hand was about to touch the sword, a powerful force pushed him back.

"It seems that this sword is not easy to obtain." Lin Feng said, rubbing his chest.

Li'er thought for a moment and said, "Brother Lin Feng, perhaps we need to solve the mystery in this temple."

So they began to look for clues in the temple, and after some effort, they finally found a clue on a mural.

Following the instructions on the mural, they unlocked a series of mechanisms. The seal on the sword was finally lifted, and Lin Feng successfully grasped the sword.

At this moment, the temple began to shake violently and seemed to be collapsing.

Lin Feng and Li Er quickly fled the temple. However, as soon as they walked out of the temple, they were surrounded by a group of mysterious people.

"Hand over your sword and I will spare your life!" the mysterious man shouted.

Lin Feng and Li'er looked at each other and decided to fight to the death.

A fierce battle begins...
