Genshin Impact.

Lin Feng and Li'er went through many hardships in the test of the heart tribulation and finally made a breakthrough. However, before they could even catch their breath, a new journey had already begun.

The old man looked at the two of them, a glimmer of relief flashed in his eyes, and he said, "The heart tribulation has passed, but your path to immortality is still far away. Next, you need to go deep into the mortal world and find your own way through the various trials of the mortal world, so that you can truly embark on the right path to immortality."

Lin Feng's eyes were firm, and he bowed and said, "Don't worry, senior. Li'er and I will do our best and live up to your trust." Li'er also nodded slightly, her eyes full of determination.

Under the guidance of the old man, the two stepped into the mortal world. This mortal world was bustling and noisy, completely different from the place where they had cultivated immortality before.

When they first came into the world, Lin Feng and Li Er were full of curiosity about everything. On the streets, people were coming and going, the hawkers were shouting one after another, and all kinds of novel toys were dazzling.

"Brother Lin Feng, this world is so lively." Li'er looked around with an excited smile on her face.

Lin Feng smiled and nodded: "Yes, but we must not forget our mission when we come to the mortal world to experience disasters this time."

At this moment, a little boy suddenly rushed out from the crowd and accidentally bumped into Li'er. The little boy fell to the ground, and the candied haws in his hand also fell to the ground.

Li'er quickly helped the little boy up and asked with concern: "Little brother, are you okay?"

The little boy looked at Li'er, a trace of fear flashed in his eyes, and he turned and ran away. Lin Feng and Li'er looked at each other, feeling a little strange.

They followed the direction the little boy ran and came to a remote alley, where they saw the little boy being surrounded by a group of bullies, who were beating and kicking him.

"Stop!" Lin Feng shouted and rushed forward.

When the bullies saw Lin Feng, they were stunned at first, and then they smiled disdainfully: "Where did this little brat come from? How dare he meddle in other people's business?"

Lin Feng's eyes turned cold, and a powerful aura emanated from his body. The bullies felt this aura, and were immediately frightened and pale, begging for mercy.

Lin Feng ignored them, helped the little boy up, and asked, "Little brother, why did they bully you?"

The little boy looked at Lin Feng, tears in his eyes: "They took away the money I earned from selling candied haws. That was the money I used to buy medicine for my grandma."

Li Er felt sad when she heard this: "Brother Lin Feng, let's help him."

Lin Feng nodded, took out some silver from his pocket and handed it to the little boy: "Little brother, use this money to buy medicine for grandma."

The little boy took the silver and knelt on the ground: "Thank you, you are good people."

Lin Feng and Li Er helped the little boy up and told him to be careful in the future. The little boy nodded, turned around and ran back home.

After solving the problem of the little boy, Lin Feng and Li Er continued to travel in the mortal world. They helped many people in need and also witnessed the warmth and coldness of human nature in the mortal world.

However, as time went on, they discovered that there seemed to be a mysterious power hidden in this world. Whenever they wanted to explore it, the power would disappear without a trace.

One day, Lin Feng and Li Er met a monk in a temple. The monk looked at them, and a deep meaning flashed in his eyes: "Two donors, you are shouldering a great mission, but the catastrophe of this world is coming, you must be prepared."

Lin Feng and Li'er looked at each other, and they were startled: "Master, may I ask what exactly is this calamity?"

The monk shook his head and said, "The secret of heaven cannot be revealed. Everything depends on your luck." After saying that, the monk turned and left.

Lin Feng and Li Er knew that this trip down to the mortal world would not be easy. They decided to practice harder and improve their strength to cope with the coming disaster.

During their cultivation, Lin Feng and Li Er encountered many difficulties. Their state of mind was often disturbed by the outside world, and their cultivation progress was very slow.

Just when they were confused, the old man appeared in front of them. The old man looked at the two of them and smiled: "The way to practice is in the heart. You need to get rid of distracting thoughts in order to break through the bottleneck."

Under the guidance of the old man, Lin Feng and Li Er gradually found the direction of cultivation. Their strength continued to improve, and their state of mind became more determined.

However, what they don't know is that a bigger crisis is quietly approaching...

On a dark and windy night, Lin Feng and Li'er were resting in the inn. Suddenly, a strong aura enveloped the entire inn.

Lin Feng and Li Er woke up instantly, they rushed out of the room, and saw a group of men in black standing outside the inn. These men in black exuded a strong evil aura, and it was obvious at a glance that they were not kind.

"Who are you?" Lin Feng looked at the men in black warily.

One of the men in black sneered: "Hmph, I'm here to take your lives." After saying that, the man in black pounced towards Lin Feng and Li'er.

Lin Feng and Li Er went forward without fear. A fierce battle broke out between the two sides. Lin Feng used his magic, flashing rays of light, to repel the man in black. Li Er held a long sword, her posture was agile, and her sword moves were sharp, making it difficult for the man in black to get close.

However, these men in black were powerful and well-coordinated. Gradually, Lin Feng and Li'er began to lose the upper hand.

Just when they were in dire straits, the old man appeared in time. With a wave of his hand, a powerful force burst out, instantly repelling the men in black.

"Thank you for your help, senior." Lin Feng and Li'er said gratefully.

The old man looked at them with a serious expression: "These men in black are just the vanguard, there are more powerful enemies behind. You must improve your strength as soon as possible, otherwise, it will be difficult to cope with the upcoming crisis."

Lin Feng and Li Er nodded. They knew that this journey to the mortal world was full of challenges and dangers. But they did not back down and were determined to carve out a world of their own in this mortal world, complete the journey, and embark on the true immortal path...
