Genshin Impact.

After going through a series of hardships, Lin Feng, Li Er and the old man came to a mysterious place. There were mountains and clouds here, as if hiding countless secrets. However, before they had time to appreciate the beautiful scenery, they felt a strong sense of crisis.

Lin Feng looked around vigilantly, holding the sword tightly in his hand. Li'er also looked solemn, with a hint of uneasiness in her eyes. The old man seemed more calm, and he narrowed his eyes slightly, as if thinking about something.

"The aura here is very unusual, we must be careful." The old man whispered.

Lin Feng nodded, "I felt it too. It seems like something is watching us here."

Just as they were on guard, a group of black shadows suddenly emerged from all directions. These black shadows were extremely fast and surrounded them in an instant. Lin Feng immediately swung his sword to meet the enemy, and Li'er also used magic, with rays of light shooting out from her hands. The old man stood aside, observing the situation calmly.

The shadows continued to attack, and their power was so strong that Lin Feng and Li'er were somewhat unable to resist. Lin Feng's long sword was swinging in the shadows, but he could only barely resist their attacks. Although Li'er's magic could cause some damage to the shadows, the effect was not obvious.

"What on earth are these black shadows?" Lin Feng asked while fighting.

The old man frowned and said: "These shadows may be the guardians of this place. They will not let us pass easily."

"Then what should we do?" Li'er asked anxiously.

The old man thought for a moment and said, "We must find their weaknesses before we can defeat them."

After listening to the old man, Lin Feng and Li Er began to observe the actions of the black shadows more carefully. They found that the black shadows would pause briefly when attacking, which might be their weakness.

Lin Feng immediately seized the opportunity and launched an attack when the shadow paused. His long sword accurately pierced the shadow's vital point, and the shadow screamed and disappeared. Li'er also followed Lin Feng's example, and her magic was more powerful when the shadow paused.

After a fierce battle, they finally defeated all the shadows. However, before they could breathe a sigh of relief, they found themselves in a more dangerous situation.

A huge vortex appeared in front of them, with a strong suction force, as if it was going to swallow them in. Lin Feng tightly grasped Li'er's hand to prevent her from being sucked away by the vortex. The old man used magic to try to resist the suction of the vortex.

"What is this?" Lin Feng asked in horror.

The old man said solemnly: "This may be a time and space vortex. If we are sucked in, we don't know where we will be teleported to."

"Then what should we do?" Li'er asked anxiously.

The old man thought for a moment and said, "We must find a way to break this vortex, otherwise we will all be swallowed by it."

Lin Feng and Li Er listened to the old man and began to look for a way to break the vortex. They found that there were some strange symbols on the edge of the vortex, which might be the key to breaking the vortex.

Lin Feng and Li Er began to study these symbols, trying to understand their meaning. The old man also helped, using his magic to sense the power in the symbols.

After some effort, they finally understood the meaning of these symbols. These symbols are an ancient fairy spell, as long as the spell is recited, the vortex can be broken.

Lin Feng and Li Er immediately chanted a spell, and a powerful light shot out from their hands and hit the vortex. The vortex made a roar and then gradually disappeared.

They successfully escaped the threat of the whirlpool, but they also knew that there were more dangers waiting for them ahead. They continued to move forward, carefully observing the surroundings along the way.

Soon, they came to an ancient mountain range. The mountain range was filled with a mysterious atmosphere that made people shudder. Lin Feng and Li'er looked at each other, then followed the old man into the mountain range.

The mountains were full of traps and dangers, so they had to move forward carefully. Lin Feng walked in front, using his sword to push aside the grass to prevent traps. Li'er followed behind him, always ready to use magic. The old man was at the back, protecting their safety.

After they walked for a while, they suddenly heard a low roar. This roar seemed to come from hell, making people feel creepy. Lin Feng immediately stopped and looked around vigilantly.

"What's that sound?" Li'er asked in horror.

The old man frowned and said, "This may be the sound made by a powerful monster. We must be careful."

Just as they were on guard, a huge monster rushed out of the mountain. The monster was covered with black scales, and its eyes were flashing red. A stream of black flames spewed out of its mouth and rushed towards Lin Feng and the others.

Lin Feng immediately swung his sword to meet the enemy. His sword collided with the flames of the monster, making a loud noise. Li'er also used her magic. Rays of light shot out from her hands and hit the monster. The old man stood aside, observing the situation calmly.

The power of the monster was very strong, and its flames made it difficult for Lin Feng and Li Er to resist. Lin Feng's sword gradually became dim under the monster's attack, and Li Er's magic also lost its former power.

"This monster is too powerful, what should we do?" Lin Feng asked anxiously.

The old man thought for a moment and said, "We must find its weakness before we can defeat it."

After listening to the old man, Lin Feng and Li Er began to observe the monster's actions more carefully. They found that the monster would pause briefly when attacking, which might be its weakness.

Lin Feng immediately seized the opportunity and launched an attack when the monster paused. His long sword accurately pierced the monster's vitals, and the monster let out a scream and fell to the ground.

They successfully defeated the monsters, but they also knew that there were more dangers waiting for them ahead. They continued to move forward, encountering various monsters and traps along the way. But they relied on their courage and wisdom to overcome dangers again and again.

Finally, they arrived in front of an ancient palace. The palace exuded a powerful aura that made people feel awe. Lin Feng and Li'er looked at each other, then followed the old man into the palace.

The palace was filled with all kinds of mysterious symbols and patterns, which made people feel dizzy. Lin Feng and Li Er began to study these symbols and patterns, trying to understand their meaning. The old man helped on the side, using his magic to sense the power in the palace.

After some effort, they finally understood the meaning of these symbols and patterns. These symbols and patterns are a kind of ancient immortal arts inheritance. As long as you master this immortal art, you can improve your strength.

Lin Feng and Li Er began to practice this magic. They were immersed in the world of magic and forgot the passage of time. The old man was guarding them to prevent any danger.

After a period of practice, Lin Feng and Li Er finally mastered this magic. Their strength was greatly improved, and their hearts were filled with joy and a sense of accomplishment.

However, before they could be happy, they heard footsteps. They looked back and found that those mysterious people had caught up with them.

Lin Feng and Li'er immediately put away the secret book and prepared to flee from here, while the old man used magic to buy them time.

Under the protection of the old man, they successfully escaped from the palace. They continued to move forward and came to a safe cave in the valley. The cave was full of mysterious symbols and patterns. After they understood their meaning, they began to practice another ancient fairy art inheritance.

After training, their strength increased again. But a group of mysterious people appeared in the cave again, and the two sides started a fierce battle. Lin Feng found that these people were looking for the secret book of immortal arts, and they decided to leave as soon as possible. After finding the teleportation array in the hidden passage, they were teleported to a beautiful valley.

They rested in the valley and discussed the next steps. Lin Feng thought they needed more practice to improve their strength, and Li Er suggested looking for immortal arts secrets or treasures. The old man reminded them not to take it lightly. They decided to move on and look for more opportunities to improve their strength.
