Genshin Impact.

After taking a short break in the mysterious valley, Lin Feng, Li Er and the old man set out on the unknown immortal journey again. They knew that the road to the mortal world was not an easy one and that every step might hide a huge crisis, but their faith never wavered.

After leaving the valley, they walked along the winding path. The scenery around them was like a dream, but they had no intention of appreciating it because the air was filled with a strange atmosphere.

"Everyone be careful, the atmosphere here is very unusual." The old man warned in a low voice.

Lin Feng held the sword tightly, his eyes determined. Li'er nodded slightly, the light of the magic in her hand looming.

They continued walking and soon came to a foggy forest. The forest was silent except for the occasional strange bird calls, which made people feel creepy.

"This forest looks dangerous. Should we take a detour?" Li'er asked worriedly.

Lin Feng shook his head: "We can't take a detour. Time is running out. We must complete the calamity mission as soon as possible. Moreover, I feel that there may be important clues hidden in this forest."

The old man pondered for a moment and said, "Lin Feng is right. We cannot retreat. But we must be extra careful. There may be various dangers hidden in the forest."

So they walked into the forest carefully. In the fog, their vision was limited, and they could only rely on their keen perception and experience to move forward.

After walking for a while, I suddenly heard a low roar. This roar seemed to come from an ancient beast, which made me shudder.

"Everyone be careful, something is approaching." Lin Feng said vigilantly.

As soon as he finished speaking, a huge black shadow rushed out from the mist. It looked like a tiger, but was several times larger than an ordinary tiger, and exuded a powerful aura.

Lin Feng swung his sword without hesitation to meet the enemy, and the long sword flashed with brilliant light. Li'er also quickly performed a magic trick, and the light shot towards the black shadow.

However, the black shadow was very powerful and easily avoided Lin Feng's attack and rushed over. Seeing this, the old man immediately used a powerful magic, and a ray of light enveloped the black shadow, temporarily restricting its movements.

"This monster is not easy to deal with. We must find its weakness." said the old man.

Lin Feng and Li Er nodded and began to observe the black shadow's actions carefully. After some observation, they found that the black shadow's eyes seemed to be its weakness.

Lin Feng seized the opportunity and struck with all his strength, his sword accurately piercing the black shadow's eyes. The black shadow roared in pain and fell to the ground.

They successfully defeated the shadow and continued on their way, encountering various strange creatures and traps along the way.

Deep in the forest, an ancient relic was discovered. The relic exudes a mysterious atmosphere, making people want to explore its mysteries.

"This relic looks unusual. It may hide powerful magic and treasures." Lin Feng said excitedly.

Li'er nodded: "But be careful, there may be great dangers hidden in the ruins."

The old man thought for a moment and said, "You can go in and explore, but you must be careful. If you encounter danger, retreat immediately."

They walked into the ruins carefully. The air was filled with an old atmosphere, and the walls were engraved with mysterious symbols and patterns.

Lin Feng observed the symbols and patterns, trying to find clues. Li'er used magic to sense the atmosphere, looking for treasures and magic. The old man was alert to the surroundings, preventing danger from appearing.

After exploring for a while, I found an ancient secret book of immortal arts. The secret book exudes a powerful aura, and its extraordinary features are obvious at a glance.

"This secret book must be very powerful. We can use it to improve our strength." Lin Feng said excitedly.

Li'er was also delighted: "But you must first learn the immortal arts in the secret book before you can unleash their true power."

Therefore, they decided to stay in the ruins and concentrate on practicing the secret manuals of immortal arts.

There are many difficulties in the practice, and the secret immortal arts are complicated, which requires a lot of time and energy to understand and master. But they did not give up. Lin Feng understood the essence with his perseverance and talent, and Li Er also worked hard to improve his immortal arts. The old man guided and solved the problems.

After learning the immortal technique, his strength increased, and his joy was not over yet, but he felt a strong aura approaching. It was full of evil and darkness, which made people shudder.

"Not good, a powerful enemy is approaching." The old man looked solemn.

Lin Feng and Li'er were alert, holding their weapons tightly, ready to fight.

Soon, a black shadow walked out from the depths of the ruins, emitting a dark aura and his face could not be seen clearly.

"Who are you? Why are you here?" the black shadow said in a low voice.

Lin Feng was not afraid: "We are immortals who have come down to earth to experience tribulations, and we are here to find a way to improve our strength."

The shadow sneered: "This is my territory, you must pay the price."

After saying that, he launched an attack with such a powerful force that it seemed to be able to destroy everything.

They engaged in a fierce battle, but found that their attacks had little effect on the shadow.

"Only by finding the shadow's weakness can we defeat it," said the old man.

After observation, he found that the heart was the weak point. Lin Feng attacked with all his strength and the black shadow fell to the ground.

They continued to explore and found a mysterious teleportation array in the deepest part of the ruins. They decided to take a risk and were teleported to a strange valley.

The valley was filled with strange plants and creatures, and deep inside was an ancient temple. The temple exuded a sacred atmosphere, and they explored it carefully.

They discovered more ancient immortal arts secrets and decided to practice. There were more difficulties, but they encouraged each other, understood the essence, and their strength increased again.

At this time, a stronger aura approaches, and a figure walks out, with a sacred aura all over his body. He asks them to accept the test, find out that the head is a weak point in the battle, and defeat the figure.

Continue to explore, find the mysterious passage, and come to a huge cave. There is a powerful crystal ball in the cave. Trigger the mechanism to be bound by the light, and fuse the magic to get rid of it.

There is a portal deep in the cave, and you can venture into a mysterious world. The world is full of mystery and has an ancient castle.

The most ancient secret book of magic was found in the castle. Although it was extremely difficult to practice, he eventually learned it and reached a new level of strength.

But a strong aura of destruction approaches, and a huge figure walks out. Lin Feng reveals his identity, and the figure wants them to pay with their lives. During the battle, he finds that the heart is a weakness, and defeats the figure with a full-strength attack.

They know that the road to immortality is still long and more challenges await them.
