Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er began their journey to the mortal world to experience the tribulation. This tribulation was related to their future destiny as immortals, and the three of them were well aware of its importance.

They landed on a vast continent with beautiful mountains and rivers, but beneath this beautiful scenery, there are countless unknown dangers and opportunities. As soon as he stepped into this land, Lin Feng felt a mysterious force pulling him, as if something was waiting for them to discover.

"Master, I always feel that there is an indescribable weirdness here." Lin Feng frowned and said while looking around.

The old man stroked his beard and nodded slightly: "This time I came to the mortal world to experience the tribulation, which is full of variables. Disciples, you must not take it lightly."

Li'er's eyes were firm: "Master, don't worry, we will be careful and cautious."

The three of them walked forward and soon arrived at a prosperous town. The town was bustling with people and hawking sounds. However, under this lively appearance, Lin Feng sensed a hint of something unusual.

Suddenly, a black shadow flashed past them, so fast that they had no time to react. Lin Feng's heart trembled, and he immediately chased after it. Li'er and the old man followed closely behind.

The shadow shuttled through the narrow alleys, and Lin Feng, relying on his keen sense of immortal power, kept chasing it. Finally, the shadow stopped in front of an abandoned temple.

When Lin Feng and others arrived, they saw the shadow gradually reveal its figure. It turned out to be a mysterious man in a black robe. A layer of mist covered the face of the mysterious man, making it difficult to see his face clearly.

"Who are you? Why did you lead us here?" Lin Feng asked vigilantly.

The mysterious man laughed deeply and said, "Your arrival is destined. There are great opportunities hidden on this continent. It all depends on whether you have the ability to obtain them."

After saying this, the mysterious man disappeared into a puff of black smoke.

The old man looked at the direction where the mysterious man disappeared, thinking: "It seems that the opportunity under this variable is not so easy to obtain."

Li'er said: "Master, no matter what difficulties lie ahead, we must not retreat."

Lin Feng nodded in agreement, and the three decided to continue searching for clues in the town.

In an inn in the town, they met a young knight named Bai Yu. After hearing about their purpose, Bai Yu showed great interest in their immortal journey and decided to help them.

"There are many ancient legends and mysterious places on this continent, which may be related to the opportunities you are looking for." Bai Yu said.

Led by Bai Yu, they came to a mysterious forest filled with fog, towering trees, and strange noises from time to time.

Lin Feng walked ahead carefully, holding his sword tightly in his hand. Suddenly, a huge python jumped out from the tree, opened its bloody mouth and pounced on them. Lin Feng flashed and swung his sword to cut the python.

Li'er also used her magic, and beams of light shot towards the python. Under the joint attack of everyone, the python gradually lost and finally fled away.

They continued to go deeper into the forest, and found an ancient ruin deep in the forest. The door of the ruin was closed, and there were strange runes engraved on the door.

The old man studied the runes carefully, trying to find a way to open the door. After some effort, the old man finally cracked the secret of the runes, and the door slowly opened.

An ancient and mysterious atmosphere blew from the ruins. The three entered the ruins and saw various precious magic weapons and secret books placed inside. However, among these treasures, there were many hidden traps.

Lin Feng accidentally triggered a mechanism, and suddenly, countless sharp arrows shot out from the wall. He dodged hastily, and was in danger. Li'er used magic to create a shield to protect everyone.

After searching for a long time in the ruins, they finally found an ancient secret book. The secret book recorded a powerful immortal method, but to practice this immortal method, a huge price must be paid.

Lin Feng fell into deep thought: "Master, although this immortal method is powerful, the price is too high. Should we practice it?"

The old man said: "Opportunities are rare, but we must weigh the pros and cons. Let's take the secret book back first, and then make plans."

Just as they were about to leave the ruins, they suddenly began to collapse. Huge rocks rolled down and the ground shook.

"Oh no, let's go!" the old man shouted.

Everyone ran desperately in the collapsed ruins and finally escaped from the ruins at the last moment.

After returning to the town, they began to study the secret book. After many days of discussion, they decided to take the risk and practice this magic.

The process of cultivation was extremely difficult, and both Lin Feng and Li Er endured great pain. But with their firm will, they finally succeeded in cultivating the immortal method.

However, their actions attracted the attention of some evil forces, who coveted their magic and began to plot a conspiracy.

One night, Lin Feng and his companions were resting in the inn. Suddenly, a group of men in black broke into the inn and attacked them.

Lin Feng and Li Er fought back and started a fierce battle with the men in black. The old man also used powerful magic to repel the men in black one by one.

But the men in black kept coming and gradually surrounded them.

At this critical moment, Bai Yu led a group of righteous people to come to help. With the joint efforts of everyone, the man in black was finally repelled.

"Thank you Brother Baiyu and everyone for your help." Lin Feng said gratefully.

Bai Yu smiled and said, "There's no need to be polite between friends. But these evil forces won't give up, so we still need to be careful."

After this battle, Lin Feng and others realized that they had been involved in a huge vortex. But they were not afraid and were determined to continue to explore opportunities and complete the road of tribulation.

In the days that followed, they continued to encounter challenges and difficulties, but they also continued to grow through these hardships. They believed that as long as they persisted, they would be able to find opportunities under the variables and open a new chapter in their immortal journey.
