Genshin Impact.

After successfully defeating the mastermind and saving the world, Lin Feng, Li Er and the old man did not stop their steps. They knew that although the immediate crisis had been resolved, the dark forces in the world might still revive.

The three decided to stay in the town for a while to help the people rebuild their homes, while also keeping an eye out for any potential threats.

During this period, Lin Feng helped the people repair their houses every day. He used magic to lift heavy wood easily and put it in the right place accurately. Li'er used her healing magic to heal the injured people, so that they could recover as soon as possible and return to their lives. The old man told everyone the secrets of magic and the power of justice, inspiring everyone's confidence.

However, the peaceful days did not last long. One day, Lin Feng heard some strange rumors at the market. It was said that in the far north, a mysterious ice city appeared, which was covered with ice and snow all year round and exuded a strange atmosphere. Some people said that it was a cursed city, while others said that there were huge treasures and mysterious powers hidden there.

Lin Feng brought this news back to discuss with Li'er and the old man. The old man frowned, thought for a moment and said: "This matter may not be simple, perhaps it is another new test." Li'er's eyes flashed with curiosity: "Maybe this is a good opportunity for us to improve our immortal power."

After some discussion, the three decided to go to the ice city in the north to find out.

They walked along the rugged mountain road. The further north they went, the lower the temperature became. The surrounding scenery gradually changed from lush forests to snowy wastelands. The cold wind howled and blew on their faces like a knife.

Finally, the Ice City appeared before their eyes. The city towered into the sky, and the city walls were made of huge ice blocks, exuding a cold atmosphere. The city gates were closed, and there was no sign of any life.

Lin Feng walked forward and tried to push the gate open, but found that it did not move at all. He increased his strength, and the immortal power surged in his body, but the gate still did not respond.

Seeing this, Lier cast a warm spell to try to melt the frost on the city gate. However, as soon as the spell touched the city gate, it was bounced back by a powerful force.

After observing it for a while, the old man said, "There seems to be a powerful sealing spell on this city gate. We need to find a way to break it."

So, the three began to look for clues around the Ice City. They found some strange runes engraved on the city wall and some mysterious patterns on the ground. After careful research, the old man finally found the key to cracking the seal.

Lin Feng used his power again, and this time, the city gate slowly opened, and a biting cold wind rushed out of the city. They walked into the Ice City carefully, and saw that the city was silent, and the houses on both sides of the street were covered with ice and snow, as if time had stopped here.

Suddenly, a low roar came from a distance. The three looked in the direction of the sound and saw a huge ice beast walking out of the shadows. It was huge, covered with sharp ice spikes, and its eyes were flashing with a ferocious light.

Lin Feng rushed forward without hesitation and started a fierce battle with the ice beast. His immortal sword left scars on the ice beast's body, but the ice beast had a strong recovery ability and the wounds healed instantly.

Li'er continued to cast buff spells on Lin Feng to increase his strength and defense, while the old man observed the ice beast's attack pattern, looking for its weaknesses.

After a tough battle, Lin Feng finally found the ice beast's weakness in its abdomen. He leaped up and used all his strength to pierce the sword into the ice beast's abdomen. The ice beast roared in pain, fell to the ground, and turned into a pile of ice.

After defeating the ice beast, they continued to explore the ice city. In an ancient palace, they found a mysterious ancient book. The book recorded the origin of the ice city and the method to remove the curse.

It turns out that this ice city was once the territory of a powerful immortal. But later, the immortal was corrupted by evil forces and fell into madness, and cursed the city, making it forever covered with ice and snow. To lift the curse, you must find the three magic weapons left by the immortal and place them in three corners of the city.

Lin Feng, Li'er and the old man decided to search for magic weapons separately. Lin Feng found the first magic weapon, the Ice Soul Pearl, in an ice cave. Li'er found the second magic weapon, the Cold Wind Bell, on the top of a tower. The old man found the third magic weapon, the Frost Sword, in the city's underground maze.

They took the magic weapons and placed them in the corresponding positions according to the instructions in the ancient books. In an instant, a ray of light shot up into the sky, covering the entire ice city. The ice and snow began to melt, and the city gradually regained its vitality.

Just as they were rejoicing over the removal of the curse, a dark force emerged from underground, and a dark shadow appeared before them. It was the immortal who was corrupted by the evil force.

The immortal's eyes widened with anger, and he shouted, "How dare you break my curse!" As he spoke, he cast a powerful spell and attacked the three people.

Lin Feng, Li'er and the old man fought side by side in a life-and-death contest with the immortals. Their immortal arts collided in the air, emitting brilliant light.

The battle entered a white-hot stage, and Lin Feng and his men gradually felt powerless. At this moment, the immortal power in Lin Feng's body suddenly burst out, and his body radiated a dazzling light. Under the illumination of this light, the evil power of the immortal began to fade.

Finally, the immortal regained his sanity. He looked at Lin Feng and the others with gratitude: "Thank you for freeing me from the control of evil."

With the recovery of the immortal, the curse of Ice City was completely lifted. Lin Feng, Li'er and the old man also greatly improved their immortal power during this tribulation.

They left the Ice City and continued on their journey to immortality. They knew that there were more challenges waiting for them, but they were fearless because their hearts were full of justice and courage.
