Genshin Impact.

Under the light of inheritance, Lin Feng and Li'er looked particularly determined. They had gone through many hardships and now stood at the critical juncture of the immortal path, their hearts full of expectations and visions for the future.

Lin Feng looked into the distance, his mind full of thoughts. "Li'er, the light of inheritance this time has given me a lot of insights, and I feel like I'm about to have a huge breakthrough." Lin Feng's voice was filled with excitement.

Li'er nodded gently, with a smart light flashing in her eyes, "Brother Lin Feng, I believe you will succeed."

At this time, the mysterious old man appeared in front of them, his eyes were deep and kind. "Lin Feng, Li'er, although the light of inheritance has given you guidance, the real practice still needs to rely on your own understanding and hard work."

Lin Feng and Li'er bowed respectfully to the old man, "Thank you for your guidance, senior."

The old man nodded slightly, "Lin Feng, there is a powerful force surging in your body. This is a sign of a breakthrough. But remember, you must calm your mind and be steady."

Lin Feng took a deep breath, slowly closed his eyes, and began to adjust his breath. A faint light gradually appeared around him, and spiritual power flowed rapidly in his meridians.

Li'er looked at Lin Feng nervously from the side, her hands clenched unconsciously.

As time passed, Lin Feng's brows were sometimes furrowed and sometimes relaxed. It was obvious that he was having a fierce battle with the power in his body.

Suddenly, Lin Feng's body shook violently, and a powerful aura burst out. The surrounding flowers, plants and trees were swayed by this aura.

"Success!" Li'er shouted in surprise.

Lin Feng slowly opened his eyes, a gleam of light flashed in his eyes. He felt the powerful and abundant power in his body, and his heart was full of confidence.

The old man smiled and said, "Yes, Lin Feng, you have successfully broken through, but this is just the beginning. Next, you will face more severe tests."

Lin Feng and Li'er looked at each other and said in unison: "We are not afraid!"

The old man nodded and said, "There is a mysterious place on this immortal path. It is said that there is a secret book of supreme immortality hidden there. But if you want to obtain it, you must pass many levels."

Lin Feng said without hesitation: "Senior, we are willing to go and give it a try."

So, under the guidance of the old man, Lin Feng and Li'er embarked on a new journey.

They passed through dense forests, crossed turbulent rivers, and finally arrived at the entrance to the mysterious place.

The entrance was filled with a thick fog, making it difficult to see what was inside. Lin Feng took the first step cautiously, and Li'er followed closely behind.

As soon as they entered, they felt a strong pressure coming towards them. Strange runes flashed on the surrounding walls, as if warning intruders.

Lin Feng and Li'er supported each other and moved forward with difficulty.

"Brother Lin Feng, I'm a little scared." Li'er's voice trembled slightly.

Lin Feng held Li'er's hand tightly, "Don't be afraid, I'm here."

As they walked, they came to a huge maze. The paths in the maze were complicated and they would get lost if they were not careful.

Lin Feng calmed down, carefully observed the surrounding environment, and tried to find the right path.

After some efforts, they finally walked out of the maze. However, what was waiting for them was a more difficult challenge.

In front of them, a group of powerful demons appeared. These demons were huge, had hideous faces, and exuded a terrifying aura.

Lin Feng did not flinch, he raised his sword and rushed towards the demon. Li Er also used her own magic to help Lin Feng.

A fierce battle broke out. Lin Feng fought a desperate battle with the demons. His sword streaked across the air, and each strike contained powerful force.

Li'er's magic was like gorgeous fireworks, constantly attacking the demons.

After a hard battle, they finally defeated the demons.

However, before they could catch their breath, new tests came.

On the following journey, they encountered various traps, including flames, boulders, and ice spikes. However, Lin Feng and Li'er relied on their tenacious will and tacit cooperation to overcome dangers again and again.

Finally, they arrived at the core of the mysterious land.

There, there was a secret book of immortal magic emitting a dazzling light.

Lin Feng and Li'er walked towards the secret book excitedly. Just when they were about to touch the secret book, a powerful barrier suddenly appeared and blocked them out.

"What should we do?" Li'er said anxiously.

Lin Feng pondered for a moment, "We will definitely find a way to break through this barrier."

They began to carefully study the structure of the barrier and tried to break it using various methods.

After countless attempts, Lin Feng finally found the flaw in the barrier.

He gathered all his strength and launched a final attack towards the flaw.

With a loud bang, the barrier was broken and the secret book of immortal arts appeared before them.

Lin Feng and Li'er smiled at each other, then reached out and picked up the secret book.

The moment they picked up the secret book, a powerful force surged into their bodies.

They closed their eyes and felt the baptism of this power.

When they opened their eyes again, they found themselves back in front of the old man.

The old man looked at them with satisfaction, "You have done very well. This experience will surely make your immortal journey more glorious."

Lin Feng and Li'er bowed to the old man gratefully, "Thank you for your guidance, senior."

The old man waved his hand and said, "Go ahead. The road ahead is still long. I hope you can keep your original aspirations in mind and forge ahead."

Lin Feng and Li'er nodded, turned around and embarked on a new journey. Their figures gradually faded away in the afterglow of the setting sun...
