Genshin Impact.

Lin Feng, Li'er and the old man's journey through the mortal world continues.

They left the previous town and stepped into a vast forest. The forest was deep and quiet, and the sunlight shone through the gaps between the leaves, forming patches of mottled light and shadow. Lin Feng walked in front, observing the surroundings vigilantly, while Li'er looked at the surrounding exotic flowers and plants curiously, and the old man followed behind slowly, thinking about something.

Suddenly, a gust of wind whistled by, mixed with an evil breath. Lin Feng's heart tightened, and he signaled Li'er and the old man to be careful. A huge monster slowly walked out of the woods ahead. It was as big as a mountain, and its eyes were flashing with fierce light.

Lin Feng was not afraid at all, holding a long sword, he flew towards the monster. Li'er was not to be outdone, she cast a spell to bless Lin Feng. The old man watched the monster's flaws and was ready to help at any time.

Lin Feng fought fiercely with the monster, his sword flashed through the air, and each sword contained his firm will. However, the monster had thick skin and flesh, and Lin Feng's attack did not cause much damage to it.

Seeing this, Li'er increased the output of magic, and beams of light shot towards the monster, slowing its movements slightly. At this moment, the old man discovered the monster's weakness and shouted loudly: "Lin Feng, attack its abdomen!"

Hearing this, Lin Feng dodged the monster's attack and stabbed it in the abdomen. This sword, condensing all of Lin Feng's strength, finally pierced through the monster's defense. The monster roared in pain and fell to the ground.

After this battle, the three of them were a little tired. They found an open space and took a short rest.

"There are more dangers in this world than we imagined." Li'er sighed.

Lin Feng nodded: "But this is also the meaning of our tribulation."

The old man looked at them with a smile: "Yes, only by experiencing hardships can one truly understand the true meaning of the immortal path."

After resting, they continued on their way. Soon, they came to a village. The people in the village lived in poverty and were plagued by diseases. Lin Feng and others decided to help them.

Li'er used her magic to treat the villagers, while Lin Feng helped them repair their houses and cultivate their farmland. The old man taught them some life wisdom and skills.

With their help, the village gradually regained its vitality. The villagers were so grateful to them that they took out their own food and specialties to thank them.

Lin Feng and others declined the villagers' kindness and continued their journey.

Along the way, they met all kinds of people and things. Some people did whatever it took to gain power, while others held on to kindness and justice. During these experiences, Lin Feng and others constantly pondered the good and evil of human nature and the meaning of life.

In an ancient temple, they met a great monk, who saw their extraordinaryness and talked with them about Buddhism and the path to immortality.

"The so-called path to immortality is not just about pursuing powerful strength, but also about having a compassionate heart and caring for all things in the world," said the monk.

Lin Feng and others were deeply inspired and gained a new understanding of the path to immortality.

After leaving the temple, they continued on their way. Suddenly, the sky was covered with dark clouds, lightning and thunder. A mysterious light descended from the sky and landed in front of them.

After the light faded, an ancient secret book appeared. Lin Feng went forward and picked up the secret book, only to see the words "Worldly Heart Sutra" written on it.

They opened the secret book and found a powerful cultivation method recorded in it. However, this cultivation method requires abandoning distractions and focusing on it.

Lin Feng and his companions decided to find a quiet place to concentrate on their practice. They came to a valley, built a simple residence in the valley, and began to practice.

The process of cultivation was not smooth. Lin Feng's mind was always disturbed by the various things in the world, and Li'er was often unable to concentrate because of impatience. The old man patiently guided them and asked them to adjust their mentality.

After a long period of hard work, Lin Feng finally broke through the bottleneck and his cultivation level improved significantly. Li'er also successfully mastered a new spell.

Just as they were about to leave the valley, they found that the outside of the valley was blocked by a powerful force. It turned out that this was a trap set by an evil organization, who coveted the secret book in the hands of Lin Feng and others.

Faced with a powerful enemy, Lin Feng and others did not retreat. They worked closely together and launched a life-and-death battle with the evil organization.

After a fierce battle, they finally defeated the evil organization and lifted the blockade.

However, they also know that the challenges in the mortal world are far from over. They will continue to move forward, continue to grow in the tribulations, and find their own immortal path.
