Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er plunged into the mortal world and began to experience the tribulation. The pressure of the immortal tribulation enveloped them, but there was no fear in their eyes, only firm determination and expectations for the future.

After coming down to earth, Lin Feng and Li'er landed in a prosperous ancient city. There were a lot of cars and people coming and going here, which was completely different from the fairyland they were in before. They wore ordinary people's clothes and tried to fit into this new world.

"Brother Lin Feng, it's so lively here, but I don't know how our journey will unfold." Li'er looked at the scene around her, her eyes full of curiosity.

Lin Feng gently held Li'er's hand and comforted her: "Don't be afraid, no matter what difficulties and obstacles you encounter, I will protect you."

At this moment, a ragged beggar suddenly rushed over and hugged Lin Feng's legs: "Sir, please have mercy on me, I haven't eaten for several days."

Lin Feng felt pity and took out a few copper coins from his pocket and handed them to the beggar. However, when the beggar took the copper coins, his eyes suddenly became fierce, and a dagger appeared in his hand and stabbed at Lin Feng.

Lin Feng reacted quickly, dodged to the side, and subdued the beggar with his backhand. "Who are you? Why did you want to assassinate me?"

The beggar sneered: "If you want to blame someone, blame yourself for coming here. Someone paid to buy your lives!"

After saying that, the beggar muttered something, and a black mist suddenly burst out of his body. Lin Feng realized that something was wrong, and quickly protected Li'er behind him, while performing magic to disperse the mist.

However, after the fog dissipated, the beggar disappeared.

"It seems that our experience on earth has attracted the attention of some people." Lin Feng frowned.

Li'er nodded: "I just don't know who is behind this. What should we do next?"

Lin Feng thought for a moment and said, "Let's find a place to settle down first, and then make a long-term plan."

The two found an inn in the city and stayed there temporarily. At night, Lin Feng lay in bed, tossing and turning, unable to fall asleep. He knew in his heart that this tribulation was not easy, and they had to be careful to overcome the difficulties.

The next morning, Lin Feng and Li Er were about to go out, but they found that the entrance of the inn was crowded with people. When they approached, they saw a corpse lying on the ground, with a distorted face and a horrible death.

"Isn't this the beggar from yesterday?" Li'er said in surprise.

Lin Feng squatted down and carefully examined the body. He found that the beggar had multiple wounds on his body. He was obviously killed. "It seems that someone wanted to kill him to silence him and cover up the truth behind it."

At this moment, a group of officials came over and surrounded Lin Feng and Li'er. "Who are you? What do you have to do with this corpse?"

Lin Feng said calmly, "Sir, we have nothing to do with this matter. We just ran into this beggar on the street yesterday, and we didn't expect that he would be killed today."

The chief of the police looked Lin Feng and Li Er up and down and said, "Whether they are related or not is not up to you to decide. Come, take them back to the government office and interrogate them strictly!"

Lin Feng and Li'er had no choice but to follow the official to the yamen. Inside the yamen, the county magistrate sat high in the hall and slammed the gavel: "Everyone in the hall, confess the truth!"

Lin Feng recounted the whole story. After listening, the county magistrate pondered for a moment: "Words are not enough, how can I believe that what you said is true?"

At this moment, an old man suddenly appeared in the hall. "Mr. County Magistrate, everything they said is true. Please take a closer look."

When the county magistrate saw the old man, he immediately stood up to greet him and said, "So it's the immortal. Since the immortal has guaranteed them, let's just drop the matter for now."

Lin Feng and Li Er were able to escape. After leaving the government office, Lin Feng thanked the old man: "Thank you for your help, Senior. What is your name?"

The old man smiled and said, "I am Xiaoyaozi, and I have been following your journey of tribulation. This incident is just a small test, and there are more challenges waiting for you in the future."

After saying this, the old man disappeared in a flash.

Lin Feng and Li'er looked at each other and understood that their journey to immortality had just begun...

In the following days, Lin Feng and Li Er searched for clues everywhere, trying to find the mastermind behind the incident. They met a woman named Su Yao in the city. Su Yao was a rich girl with a kind heart, and she sympathized with Lin Feng and Li Er's experience.

With the help of Su Yao, Lin Feng and Li'er learned that a mysterious organization had recently appeared in the city. This organization specialized in some shady activities and was likely related to their assassination.

In order to investigate this mysterious organization in depth, Lin Feng and Li Er decided to blend in. After some disguises, they successfully infiltrated a base of the mysterious organization.

In the base, they discovered some shocking secrets. It turned out that there were forces from the fairy world behind this mysterious organization. They tried to destroy Lin Feng and Li Er's tribulation and prevent them from returning to the fairy world.

"Damn it, these people are so despicable!" Li'er said angrily.

Lin Feng comforted her, "Li'er, don't be impulsive. We must find a way to disrupt their plan so that we can successfully complete the tribulation."

Just as they were about to leave the base and go back to discuss countermeasures, they were discovered by the mysterious organization. A fierce battle was inevitable.

Lin Feng and Li Er used their magic to fight the enemy to death. However, the enemies were numerous and powerful, and they gradually fell into trouble.

At this critical moment, Xiaoyaozi appeared again, wielding a long sword in his hand. His sword moves were fierce, and wherever he went, the enemies fell down one after another.

With the help of Xiaoyaozi, Lin Feng and Li'er successfully escaped the enemy's pursuit. After returning to a safe place, Lin Feng and Li'er were grateful to Xiaoyaozi.

"Master, if you hadn't helped us this time, we would have been in great danger." Lin Feng said.

Xiaoyaozi waved his hand: "You're welcome. I'm helping you to maintain peace in the fairy world. What are your plans next?"

Lin Feng pondered for a moment and said, "We decided to take the initiative to completely eradicate this mysterious organization and restore peace to the mortal world."

Xiaoyaozi nodded: "Okay, you have great ambition! However, this mysterious organization is very powerful, you must not take it lightly. I will assist you in secret."

Therefore, with the help of Xiaoyaozi, Lin Feng and Li'er made a detailed plan. They began to collect intelligence everywhere, contact various forces, and prepare for the final decisive battle with the mysterious organization.

The day of the decisive battle finally arrived. Lin Feng and Li Er led a group of like-minded people to the headquarters of the mysterious organization. After the leader of the mysterious organization learned of their actions, he had already laid a net and waited for their arrival.

When Lin Feng, Li Er and others entered the headquarters of the mysterious organization, they were immediately besieged by the enemy. The two sides launched a thrilling battle.

Lin Feng and Li'er fought side by side, using their magic to kill the enemy. However, the leader of the mysterious organization was very powerful, and he cast a powerful spell to trap Lin Feng and Li'er.

"Haha, you'll never leave here alive today!" the leader of the mysterious organization laughed triumphantly.

At this moment, Xiaoyaozi suddenly appeared. He swung the long sword in his hand, and a powerful sword energy directly broke the spell of the leader of the mysterious organization.

"You can't succeed while I'm here!" Xiaoyaozi said.

Seeing that the situation was not good, the leader of the mysterious organization wanted to escape. How could Lin Feng and Li'er let him do so? They used their strongest magic to completely defeat the leader of the mysterious organization.

With the defeat of the leader of the mysterious organization, the mysterious organization also collapsed. Lin Feng and Li Er successfully completed the mission of experiencing the tribulation, and their immortal hearts were also tempered and sublimated in this tribulation.

"Brother Lin Feng, we finally succeeded." Li'er threw herself into Lin Feng's arms and cried with joy.

Lin Feng hugged Li'er tightly: "Yes, we succeeded."

At this moment, a beam of auspicious light sprinkled down from the sky, covering Lin Feng and Li'er. Their figures gradually disappeared, and they returned to the fairyland...
