Genshin Impact.

After many twists and turns, Lin Feng and Li Er finally found inner peace and direction at this moment of unity. However, their immortal journey has not ended yet, and new challenges are quietly approaching.

Lin Feng stood on the top of the mountain, looking at the sea of ​​clouds in the distance, with a lot of thoughts in his mind. Li'er walked gently to his side, and the breeze brushed her hair, adding a bit of tenderness.

"Lin Feng, what are you thinking about?" Li'er asked softly.

Lin Feng turned his head slightly, looked into Li'er's eyes, and said, "I was wondering, our immortal path is so tortuous, what will the future be like?"

Li Er smiled slightly: "No matter what the future holds, as long as we move forward hand in hand, we will be able to overcome everything."

At this moment, a mysterious old man appeared in front of them. The old man had deep eyes, as if he knew everything in the world.

"Young man, you still have a long way to go," the old man said slowly.

Lin Feng and Li'er looked at each other, then bowed respectfully to the old man: "Please give me some advice, Senior."

The old man nodded slightly: "In this world, there is a mysterious place that hides the secret of improving immortal power, but it is also full of unknown dangers."

A hint of determination flashed in Lin Feng's eyes: "Senior, we are willing to go and give it a try."

The old man smiled slightly and opened a portal with a wave of his hand: "Go, everything depends on your luck."

Lin Feng and Li Er stepped into the portal without hesitation and were instantly enveloped by light. When they opened their eyes again, they found themselves in an unfamiliar valley.

The valley was filled with thick fog and there was silence all around, which made people feel inexplicably depressed.

"Lin Feng, be careful." Li'er followed Lin Feng closely.

Lin Feng nodded and walked forward cautiously. Suddenly, a gust of wind whistled past, with a strange smell in the wind.

"This wind is wrong." Lin Feng said vigilantly.

Before he finished speaking, a group of black shadows rushed out from the thick fog and rushed towards them. Lin Feng and Li'er quickly launched a counterattack, and the immortal power in their hands burst into a dazzling light.

After a fierce battle, they finally repelled the shadow. However, before they could catch their breath, the ground began to shake 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 dodged the attack of the venom.

"Lier, find an opportunity to attack its weakness." Lin Feng shouted.

Li'er responded, and the immortal power in her hand condensed into a sharp sword, stabbing at the python's eyes. The python felt pain and twisted its body angrily.

Lin Feng took the opportunity to use his powerful magic, and a beam of light hit the python's vital point. The python fell to the ground with a bang and turned into a wisp of black smoke and dissipated.

As they continued to move forward, they encountered all kinds of strange traps and powerful monsters, but with the support of each other, they overcame them one by one.

Finally, they arrived in front of an ancient cave. The door of the cave was closed and engraved with mysterious runes.

"This should be the place the old man mentioned." Lin Feng said.

Li'er walked forward and observed the runes carefully: "These runes seem to have some kind of pattern."

After some research, they finally cracked the secret of the rune and the door slowly opened.

Inside the cave, a strange light shone, and an ancient secret book was suspended in the air.

Lin Feng reached out to take the secret book, but triggered a powerful ban. Countless rays of light shot towards them.

Li'er quickly cast a shield to block the attack of light.

At the critical moment, Lin Feng broke through the ban with his powerful immortal power and successfully obtained the secret book.

However, just as they were about to leave the cave, a powerful force enveloped them.

"Oh no, this is the guardian power of the cave." Lin Feng said.

Li'er held Lin Feng's hand tightly: "Don't be afraid, we will deal with it together."

They tried their best and launched a thrilling contest with the guardian forces.

Finally, they successfully got rid of the guardian force and left the mysterious land with the secret book.

After returning to their original world, Lin Feng and Li Er began to practice the immortal arts in the secret book. Their immortal powers continued to increase, and they gradually became legendary figures in the immortal world.

In their future journey to immortality, they may encounter more challenges, but their hearts are full of courage and faith, and they believe that they will be able to write a glorious chapter of their own.
