Genshin Impact.

After going through many hardships in the Demon Abyss, Lin Feng, Li Er and the old man finally saw a glimmer of hope. However, they knew that this was just a small turning point in the long journey to immortality, and there were more challenges and unknowns waiting for them ahead.

After coming out of the Demon Abyss, they came to a mysterious valley. The valley was filled with a strong spiritual energy, and the surrounding mountains were soaring into the clouds, as if connected to the sky.

Lin Feng looked at this strange scene, his heart full of anticipation: "This may be a great place for us to practice immortal arts."

The old man nodded slightly: "Yes, but you also need to be careful. This place may seem peaceful, but in fact it may hide many dangers."

Li'er blinked her smart eyes: "No matter what, we must face it bravely."

They began to look for a suitable place to practice in the valley. On the way, Lin Feng suddenly felt a strong force attracting him. He followed this force and found an ancient relic hidden in a cave.

"What is this place?" Li'er asked curiously.

The old man looked solemn and said, "This is probably a place of cultivation left by an ancient immortal, but it must be full of traps and tests."

Despite this, they decided to enter the ruins to explore. As soon as they entered, a powerful barrier enveloped them. Lin Feng tried to use magic to break it, but the barrier remained motionless.

"Let me try." The old man formed seals with his hands, muttered something, and a powerful immortal power surged out. However, the barrier only trembled slightly.

Just when they felt helpless, Li'er discovered some runes on the barrier.

"These runes seem to be the key to breaking the barrier." Li'er said.

After some research, they finally found the pattern of the runes and successfully broke the barrier.

Entering the ruins, there are all kinds of complicated mechanisms and puzzles. Some places require precise control of immortal power to pass through, and some places require interpretation of ancient immortal texts to find a way out.

In a huge stone chamber, they encountered a powerful guardian beast. The guardian beast was huge and exuded a terrifying aura.

Lin Feng was not afraid at all and rushed forward first. He used the magic he had just practiced and started a fierce battle with the guardian beast.

Li'er and the old man also used their unique skills to assist Lin Feng. After a hard fight, they finally defeated the guardian beast.

Deep in the ruins, they found an ancient secret book of immortal arts. Lin Feng couldn't wait to open the secret book and began to practice the immortal arts in it.

As his cultivation deepened, Lin Feng's immortal power continued to increase. But at the same time, he was also disturbed by the inner demon. The inner demon transformed into various terrifying illusions, trying to drive Lin Feng crazy.

Li Er shouted anxiously, "Lin Feng, you must keep your mind focused!"

Lin Feng closed his eyes tightly, trying to resist the temptation of his inner demon. At the critical moment, he remembered his original intention and mission, and finally succeeded in defeating his inner demon.

The old man said with relief: "Lin Feng, you have passed an important test."

However, their adventure was not over yet. On the way out of the ruins, they encountered a sudden storm. There were howling winds, lightning and thunder, and the terrain in the valley began to change.

"Everyone be careful!" Lin Feng shouted loudly.

They struggled forward in the wind and rain. Suddenly, a huge crack appeared on the ground and Li'er accidentally fell down.

Lin Feng jumped up without hesitation and grabbed Li'er's hand.

"Hold on!" The old man used his magic to pull them up.

After a lot of hardships, they finally walked out of the valley. But the road ahead is still full of challenges, they will continue to move forward bravely and pursue the true meaning of immortality.
