Genshin Impact.

After going through all kinds of hardships, Lin Feng and Li Er are still struggling forward on this long journey of mortals. Their state of mind is gradually changing in these tests.

At this moment, Lin Feng stood on the top of a towering mountain, overlooking the vast land below, with a lot of emotion in his heart. He knew that although he had been confused along the way, he also gradually awakened in every predicament.

Li'er stayed beside Lin Feng, her lively eyes showing determination and perseverance. "Brother Lin Feng, no matter how many difficulties and obstacles there are ahead, I will face them with you." Li'er's voice was gentle but full of power.

At this moment, a mysterious old man appeared in front of them. The old man's eyes were deep, as if he knew everything in the world. "Children, your immortal journey has not yet ended, and the real test is still ahead." The old man's words made Lin Feng and Li'er feel nervous.

Lin Feng bowed and asked, "Senior, please give me some advice."

The old man smiled and said, "Deep in this continent, there is a mysterious secret place hidden. There is the key to your breakthrough."

Lin Feng and Li'er looked at each other and set off in the direction the old man pointed without hesitation. Along the way, they encountered violent storms and passed through thorny jungles, but they never stopped.

Finally, they arrived at the entrance of the secret place. There was a layer of mysterious fog at the entrance, making it difficult to see the scene inside.

Lin Feng took a deep breath and stepped into the secret realm first. Li'er followed closely behind him. As soon as they entered, they felt a strong pressure coming towards them.

In the secret realm, they encountered various strange creatures and complex puzzles. Some creatures have powerful powers, which require Lin Feng and Li'er to work together to deal with; some puzzles require them to use wisdom and magic to solve.

As he went deeper into the secret realm, Lin Feng found that his immortal power seemed to be restricted in some way and it became increasingly difficult to exert it. Li'er was also facing difficulties, but she remained calm.

"Brother Lin Feng, we can't give up. There must be a way to break through these limitations." Li'er said.

Lin Feng nodded, "Well, let's think of a solution together."

Through repeated attempts and failures, Lin Feng gradually realized that this was not only a test of his immortal power, but also a tempering of his inner self.

Finally, with their unremitting efforts, they found a way to break through the difficulties. When they successfully solved the last puzzle, a dazzling light flashed, and they obtained a mysterious magic weapon.

This magic weapon exudes powerful power and seems to be able to help them break their current predicament.

However, just as they were about to leave the secret realm, they encountered a powerful guardian beast. The guardian beast roared and pounced on them, and Lin Feng and Li'er were once again in a life-and-death crisis.

But this time, they did not retreat at all. Lin Feng held the magic weapon and started a fierce battle with the guardian beast. Li Er performed magic to support Lin Feng.

After a hard battle, they finally defeated the guardian beast and successfully left the secret realm.

When they returned to the outside world, they found that their state of mind and spiritual power had greatly improved.

Lin Feng looked up at the sky, his heart filled with hope: "Li'er, our immortal path will definitely be brighter."

Li Er smiled and nodded: "Yes, Brother Lin Feng."

However, what they didn't know was that even greater challenges were waiting for them...
