Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er embarked on the journey to the mortal world to experience tribulations. They passed through the clouds and landed in a bustling town.

The town was full of life and energy, the streets were crowded with people, and people were busy and happy. Lin Feng looked around curiously, attracted by the bustling scene. Li'er followed him closely, looking a little nervous.

"Lin Feng, everything here is so unfamiliar, we have to be careful." Li'er reminded softly.

Lin Feng nodded and comforted her with a smile: "Don't worry, Li'er, I'm here."

They found an inn in the center of town and decided to stay there. At night, Lin Feng lay in bed, tossing and turning, unable to fall asleep. The old man's instructions and their mission to experience the tribulation kept emerging in his mind. Li'er was also not asleep. She lay quietly beside him, feeling Lin Feng's inner anxiety.

Lin Feng turned his head and looked at Li'er's beautiful face, and a sense of responsibility surged in his heart. He knew that this tribulation was of great significance to them, not only related to their personal growth, but also to the future of the entire fairy world. He secretly made up his mind to complete the mission and protect Li'er.

The next morning, the sun shone through the window into the room. Lin Feng got up from the bed, full of energy. He and Li'er walked out of the inn together and began to explore this new world. They strolled through the streets and alleys, tasted local food, and learned about human customs. Despite facing the unknown, they always maintained an optimistic and positive attitude, believing that through this experience, they will become more mature and stronger.

The next morning, they decided to look for some clues about the robbery. While asking around in the streets, they met a mysterious beggar.

The beggar was unkempt, but there was a hint of shrewdness in his eyes.

"You don't look like people from this mortal world, but what are you looking for?" asked the beggar.

Lin Feng and Li'er looked at each other and decided to tell the truth.

After hearing this, the beggar smiled and said, "Come with me."

They followed the beggar to a remote alley, and the beggar took out a tattered book from his arms and handed it to Lin Feng.

"This may be useful to you." After saying this, the beggar disappeared.

Lin Feng and Li'er opened the book and found that it contained some ancient legends and mysterious places about the town.

Following the instructions in the book, they came to an abandoned temple, which was eerie and filled with a strange atmosphere.

"Lin Feng, I'm a little scared." Li'er grabbed the corner of Lin Feng's clothes tightly.

Lin Feng comforted her: "Don't be afraid, I'm here."

They walked into the temple hall and saw a dilapidated statue lying on the ground. Suddenly, a light appeared on the statue and a mysterious voice sounded in their ears.

"Why are you here?"

Lin Feng replied calmly: "We are here to survive the catastrophe."

The mysterious voice was silent for a moment, "If you want to successfully survive the calamity, you must pass three tests."

As soon as he finished speaking, the first test began. Countless phantoms suddenly appeared in the temple and rushed towards them.

Lin Feng and Li Er fought side by side, using their own magic to fight fiercely with the phantoms. After a hard fight, they finally eliminated all the phantoms.

Before they could catch their breath, the second test came. A raging fire broke out in the temple, and the blazing flames seemed to devour them.

Li Er was a little flustered, "Lin Feng, what should we do?"

Lin Feng thought calmly, and suddenly remembered the spells they learned in the fairyland, "Li'er, cast the water spell with me."

They made seals with their hands and chanted something. A stream of clear water gushed out from their hands and gradually put out the fire.

Just when they thought the test was over, the third test came. The ground of the temple began to shake violently, and a huge abyss appeared. A strong suction force tried to drag them into it.

Lin Feng held Li'er's hand tightly, "Don't be afraid, let's jump over together."

They mustered up their courage, made a great leap, and finally crossed the abyss.

The mysterious voice sounded again, "You have passed the test. The road ahead will be more difficult. Be careful."

Lin Feng and Li'er left the temple and continued to explore the mortal world. However, they didn't know that a greater crisis was waiting for them.
