Genshin Impact.

Lin Feng and Li'er continued to grow in their worldly experiences, and the mysterious old man had been silently watching their every move.

One day, Lin Feng and Li'er came to a prosperous city called "Lingfeng City". The city was bustling with people coming and going, but Lin Feng keenly sensed a hint of something unusual.

"Lier, do you feel that there seems to be some mysterious power hidden in this city?" Lin Feng whispered to Lier.

Li'er nodded slightly, a hint of vigilance flashing in her beautiful eyes: "Indeed, we need to be careful."

The two were exploring the city and accidentally heard a legend about a mysterious valley outside the city. It is said that strange lights often flash in the valley, and most people who enter it never return.

Lin Feng and Li'er looked at each other and decided to go and find out what was going on.

When they arrived at the entrance of the valley, they saw clouds and mist all around, and it was eerie and scary. Lin Feng took a deep breath and stepped in first. Li'er followed closely behind, holding the magic weapon tightly in her hand.

The valley was filled with thick fog, and Lin Feng and Li'er moved forward cautiously. Suddenly, a gust of wind whistled past, mixed with sharp cries.

"Be careful!" Lin Feng pulled Li'er behind him, and saw several black shadows rushing towards them.

Lin Feng used his magic, shining with light, and started a fierce battle with the shadow. Li Er was not to be outdone and assisted Lin Feng in resisting the attack.

After a hard fight, they finally defeated the shadow, but at this point they had lost their way.

"What should I do?" Li'er was a little anxious.

Lin Feng calmly observed his surroundings and suddenly found a tree with a peculiar shape. "Maybe this tree can show us the way out."

As they walked towards the tree, the ground suddenly shook violently and a huge python emerged from the ground.

The python opened its bloody mouth and spewed out a stream of black venom. Lin Feng and Li'er quickly dodged and started a new round of battle.

During the fierce battle, Lin Feng discovered that the python's weakness was a scale on its head. He and Li'er cooperated with each other and finally succeeded in hitting the python's weakness and subduing it.

As the python fell, the fog gradually dissipated and they found the exit.

After leaving the valley, Lin Feng and Li'er continued on their way. On the way, they met an injured immortal.

The immortal told them that he was looking for a lost artifact, but was unfortunately attacked by evil forces.

Lin Feng and Li Er decided to help the immortal. Under the guidance of the immortal, they came to an ancient castle.

The castle was full of traps, and every step was full of danger. But with Lin Feng's intelligence and Li'er's bravery, they successfully cracked the traps one after another.

Finally, they found the artifact. However, just as they were about to take it away, a group of evil immortal cultivators appeared and tried to snatch it away.

"Don't even think about it!" Lin Feng roared and faced the enemy together with Li'er.

The two sides launched a thrilling battle. Lin Feng and Li Er worked closely together and used all their skills.

At the critical moment, the immortal power in Lin Feng's body suddenly burst out, shining brightly and repelling the enemy.

With the magic weapon, they returned to the immortal, who was very grateful and gave them a mysterious immortal secret book as a reward.

Lin Feng and Li'er continued to gain experience in the mortal world. Their strength continued to improve, and their state of mind became more determined.

However, a bigger crisis is quietly approaching.
