Genshin Impact.

After a short rest on the misty fairy mountain, Lin Feng, Li'er and the old man are about to embark on this earthly trial journey.

Lin Feng stood tall, his eyes revealed determination and expectation, and his white clothes fluttered gently in the breeze. Li'er was wearing a light pink dress, her smart eyes sparkling with curiosity and courage. She stood close to Lin Feng, as if as long as he was by her side, no matter what difficulties and obstacles lay ahead, she would not be afraid. And the old man, with a fairy-like appearance and wisdom and vicissitudes in his eyes, would serve as the guide of this trial and lead the two into this unknown world.

“Lin Feng, Li’er, the trials in this mortal world are extremely difficult, but they are also necessary trials on your journey to becoming immortals. Remember not to take them lightly.” The old man said earnestly.

Lin Feng and Li'er looked at each other and responded in unison: "Disciple will follow your instructions."

The old man nodded slightly, and waved the whisk in his hand lightly, and a teleportation array shining with mysterious light appeared in front of the three people. "Once you step into this array, you will descend to the mortal world. During the trial, I cannot give you direct help, everything depends on you."

Lin Feng took a deep breath and took the lead to step into the magic circle, followed closely by Li'er. In the flash of light, the figures of the three disappeared on the fairy mountain.

When the light faded, Lin Feng and Li Er found themselves in a prosperous ancient city. There were shops on both sides of the street, shouts and hawking sounds came one after another, and people came and went, making it very lively.

"Wow, it's so lively here!" Li'er looked around excitedly.

Lin Feng was also attracted by the scene before him, but he quickly collected his thoughts and reminded Li'er, "Don't forget our trial mission and don't be blinded by the prosperity of this world."

Li'er stuck out her tongue and nodded obediently.

At this time, the old man's voice sounded in their minds: "In this trial, you need to help the people of this ancient city solve a mysterious disaster within three months. The source of the disaster is hidden in the dark, and you need to explore it carefully. In addition, during the trial, you need to experience the emotions and sufferings of the world as much as possible, which will greatly benefit your practice."

Lin Feng and Li Er began to explore the ancient city, trying to find clues about the mysterious disaster. They found that in recent times, the farmland around the ancient city has been inexplicably destroyed, the crops have failed, and the people are suffering. Moreover, every night, there are bursts of strange noises coming from the forest outside the city, which makes people shudder.

In order to find out the truth, Lin Feng and Li Er decided to go to the forest outside the city at night to find out. As night fell and the moonlight was like water, the two walked into the forest carefully. There was a thin layer of mist in the forest, making the vision blurred.

Suddenly, a chilly wind blew, and the leaves rustled. Li'er unconsciously moved closer to Lin Feng, her voice trembling a little: "Brother Lin Feng, I'm a little scared."

Lin Feng held Li'er's hand and gave her a comforting look: "Don't be afraid, I'm here."

At this moment, a low roar came from the front. The two looked closely and saw a huge monster appeared in front of them. The monster was covered with hard scales, its eyes were flashing blood-red light, and it opened its bloody mouth and pounced on them.

Lin Feng was not afraid, he drew his sword and faced the monster. Li Er also cast a spell to bless Lin Feng. For a moment, the sword shadow flickered and the magic light intertwined. After a fierce battle, Lin Feng finally found the monster's weakness and stabbed it in the vitals with a sword, and the monster fell to the ground with a bang.

However, they soon discovered that the monster was not the source of the disaster, but just a small minion. Deep in the forest, there seemed to be a more terrifying existence hidden.

In the following days, Lin Feng and Li Er continued to investigate. They found an abandoned castle deep in the forest. The castle was filled with an evil atmosphere that made people shudder.

The two walked into the castle carefully. The castle was dark and damp, with mosses on the walls and a foul smell in the air. In the hall of the castle, they found a huge magic circle. The magic circle flashed with strange light, as if some evil ritual was being performed.

Just as they approached the magic circle, a black shadow emerged from the magic circle and attacked them. Lin Feng and Li Er fought back, but the black shadow was too powerful and they gradually fell into trouble.

At the critical moment, Lin Feng suddenly realized a new sword technique. He used this new sword technique and attacked the black shadow like a storm. Under this powerful attack, the black shadow gradually revealed its flaws. Li Er took the opportunity to cast a powerful spell and hit the black shadow.

The shadow screamed and turned into a wisp of black smoke and disappeared into the air. However, the light of the magic circle was still flickering, and the crisis of disaster had not been resolved.

Lin Feng and Li Er carefully studied the magic circle and found that there was a black gem inlaid in the core of the magic circle. They guessed that as long as the gem was destroyed, the magic circle could be destroyed and the disaster could be resolved.

Lin Feng mustered up his courage and walked towards the gem at the core of the magic circle. Just as he was about to touch the gem, a powerful barrier suddenly appeared and bounced him back.

Seeing this, Li'er decided to join forces with Lin Feng to break the barrier. They concentrated their energy, gathered their magic power together, and attacked the barrier. After some effort, a crack finally appeared in the barrier.

Lin Feng saw the right opportunity and rushed towards the gem again. This time, he successfully broke through the barrier and took the gem out of the magic circle.

As the gem was taken out, the light of the magic circle disappeared instantly, and the evil aura also dissipated without a trace. The disaster of the ancient city was finally lifted, and the people cheered.

In this trial, Lin Feng and Li'er not only successfully completed the task, but also deeply realized the emotions and sufferings of the world, and their cultivation level was also greatly improved.

The old man appeared in front of them and nodded with satisfaction: "You have done very well. You have all gained a lot from this mortal trial. Next, it is time to return to the Immortal Mountain to continue practicing."

Lin Feng and Li Er smiled at each other and followed the old man on their return journey. Their immortal journey continued...
