Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er began their journey to the mortal world. They fell into a world called Qingyun Continent, where anime is everywhere and the power and laws of the second dimension are intertwined.

Lin Feng and Li Er landed outside a bustling town, looking at the strange and new world in front of them, their hearts filled with anticipation and anxiety. The gates of the town were open, and people were coming and going, either in a hurry or leisurely.

"Brother Feng, it's so interesting here." Li'er blinked her bright big eyes and looked around curiously.

Lin Feng smiled and nodded, "Yes, but we must not take this tribulation lightly, the test of the immortal heart has just begun."

The two walked into the town hand in hand. There were a variety of shops on both sides of the street, including magic weapon shops selling all kinds of magical weapons, food shops with fragrant aromas, and martial arts arenas displaying gorgeous anime skills.

Suddenly, there was a noise, and a group of people gathered in the center of a square. Lin Feng and Li Er got closer and saw that it was an animation skills competition. The contestants on the stage displayed various gorgeous skills, and the light and shadow were intertwined, dazzling.

"This is a good opportunity to improve my strength." A gleam of light flashed in Lin Feng's eyes.

Li'er was also eager to try, "Brother Feng, let's join in too."

Lin Feng nodded in agreement, and the two signed up for the competition. In the competition, Lin Feng and Li'er relied on their own immortal skills and their quick understanding of the power of the second dimension to overcome all obstacles. However, as the competition progressed, the opponents became stronger and stronger.

In a crucial duel, they met a pair of mysterious siblings. The brother's name is Mo Yu and the sister's name is Mo Yao. Their anime skills work together perfectly, which brings great pressure to Lin Feng and Li Er.

The competition began. Mo Yu raised his hand and a black flame rushed towards Lin Feng. Lin Feng dodged sideways, condensed a beam of immortal power in his hand, and fought back. Li Er and Mo Yao started a fierce magic battle, and colorful lights flickered on the stage.

The two sides fought hard, and Lin Feng gradually discovered that the skills of the Mo Yu brothers and sisters seemed to contain a special power of law that could weaken their immortal power.

"Lier, be careful, their skills are weird." Lin Feng reminded.

Li'er nodded and cast the spell more attentively. In the fierce battle, Lin Feng suddenly realized that they could not rely solely on immortal power, but also needed to integrate the power of the second dimension.

Therefore, Lin Feng and Li Er adjusted their tactics and began to try to combine immortal power with the second dimension law. Their attacks gradually became more powerful and strange, catching the Mo Yu brothers and sisters off guard.

In the end, Lin Feng and Li Er seized the opportunity and defeated Mo Yu and his sister in one fell swoop, winning the game. However, before the joy of victory faded, a greater crisis quietly arrived.

It turned out that their outstanding performance in the competition attracted the attention of an evil organization called Shadow Cult, which specialized in plundering the power of the strong in order to achieve the goal of ruling Qingyun Continent.

The Shadow Cult sent out a group of masters to surround Lin Feng and Li'er in a valley.

"Hmph, you two little devils, hand over your power obediently, otherwise today will be the day of your death." A black-robed man in the lead said coldly.

Lin Feng protected Li'er behind him, his eyes firm, "If you want our power, don't even think about it with your evil ways!"

The two sides launched a fierce battle, Lin Feng and Li Er used all their skills to fight the masters of the Shadow Cult. However, the Shadow Cult had a large number of people and strong strength, and Lin Feng and Li Er gradually fell into trouble.

Just when they were about to collapse, the mysterious old man suddenly appeared. With a wave of his hand, a powerful beam of immortal power burst out, repelling the masters of the Shadow Cult.

"You two are still too immature." The old man looked at Lin Feng and Li'er and shook his head slightly.

Lin Feng and Li Er lowered their heads in shame, "Thank you for saving me, Senior."

The old man sighed, "This crisis is just a small test. There is still a long way to go in the future. You must improve your strength as soon as possible to pass the test of the Immortal Heart."

Lin Feng and Li'er nodded heavily. They knew very well that there were countless challenges waiting for them on this immortal path.

Under the guidance of the old man, Lin Feng and Li Er came to a mysterious cave. The cave was filled with rich spiritual energy, and the walls were engraved with various patterns of the second dimension.

"If you practice here, you will definitely make a breakthrough." After the old man said this, he disappeared.

Lin Feng and Li Er calmed down and began to practice with concentration. They continued to comprehend the mysteries of the second dimension law and merged it with the immortal power. Time flew by, and in the blink of an eye, three months had passed.

Lin Feng and Li'er woke up from their training, and their strength had improved qualitatively.

"Brother Feng, I feel full of strength now." Li'er said excitedly.

Lin Feng smiled and nodded, "Let's go, it's time for us to meet new challenges."

The two left the cave and continued on the road to immortality. During the journey, they met many like-minded friends and fought side by side against the evil forces.

As their reputation grew, they also attracted the attention of various forces in Qingyun Continent. Some forces wanted to win them over, while others were full of jealousy and hostility towards them.

During an adventure, Lin Feng and Li Er accidentally discovered a shocking secret about Qingyun Continent. It turned out that deep in this continent, there was a dark force hidden, which had been secretly controlling everything.

In order to save Qingyun Continent, Lin Feng and Li'er decided to go deep into the danger and explore the source of this dark power. They encountered various powerful monsters and traps in a mysterious forest.

"Brother Feng, I'm a little scared." Li'er grabbed Lin Feng's arm tightly.

Lin Feng comforted her, "Don't be afraid, Li'er, as long as we work together, we will be able to overcome the difficulties."

After a difficult exploration, they finally found the source of the dark power - an ancient magic tower. The magic tower exudes an evil breath that makes people shudder.

Lin Feng and Li Er walked into the magic tower without hesitation. What awaited them was an unprecedented life-and-death test...
