Genshin Impact.

Under the guidance of the old man, Lin Feng and Li Er finally arrived at the depths of the Demon Abyss after going through many hardships. The surroundings were filled with darkness and evil, as if to devour their souls.

Lin Feng held the sword tightly in his hand, staring firmly ahead. Li'er's face was a little tired, but her eyes still shone with an unyielding light.

"Children, the core area of ​​the Demon Abyss is full of dangers. You must be careful." The old man's voice was low and serious.

Lin Feng nodded, and the immortal power in his body began to circulate slowly. He knew very well that in this dangerous place, if he was not careful, he would be doomed.

Suddenly, a gust of wind blew past, mixed with a sharp whistling sound. Lin Feng's heart shuddered, and he saw a group of black bat-like monsters rushing towards them.

"These are demon bats. They are extremely fast. Be careful when dealing with them!" the old man warned loudly.

Lin Feng flashed, and the sword in his hand swung out a sharp sword energy, instantly beheading several demon bats. Li'er also used her magic, and rays of light shot out from her hands, hitting those demon bats.

However, the number of demon bats was increasing, as if it was endless. Lin Feng frowned, and he felt that his immortal power was being consumed.

"We can't go on like this, we must find their weakness!" Lin Feng said loudly.

At this moment, Li'er discovered that the eyes of the demon bats seemed to be their weakness. Lin Feng understood what she meant and concentrated his power to attack the eyes of the demon bats.

After a fierce battle, they finally repelled the demon bat's attack. But before they could catch their breath, the ground suddenly began to shake violently.

A huge python emerged from the ground, opened its bloody mouth and pounced towards them.

Lin Feng and Li'er quickly moved aside, while the old man used powerful magic to temporarily suppress the python.

"Lin Feng, Li'er, the scales of this python are extremely hard. We have to attack from its belly!" the old man shouted.

Lin Feng and Li'er looked at each other, then rushed towards the python's belly at the same time. With the concerted efforts of the three, they finally defeated the python.

Continuing forward, they came to a huge cave. A strange light flickered in the cave, and a powerful force emanated from it.

"Is this the core of the Demonic Abyss?" Li'er said softly.

Lin Feng took a deep breath and walked into the cave carefully. Inside the cave, the walls were engraved with strange runes, which made people feel dizzy.

"Don't be confused by these runes, keep your mind clear." The old man reminded.

Lin Feng closed his eyes, adjusted his breathing, then opened his eyes and continued to move forward.

Suddenly, a dark shadow flashed past them from behind. Lin Feng turned around alertly, but found nothing.

"Be careful, this may be a shadow creature from the Demonic Abyss." said the old man.

At this moment, the black shadow appeared again and rushed towards Li'er. Lin Feng reacted instantly and waved the magic sword in his hand to block the attack of the black shadow.

After a fierce battle, they finally saw the true face of the black shadow, which turned out to be a ghost-like monster.

In the battle with the shadow creatures, Lin Feng gradually comprehended some new immortal skills. He concentrated his immortal power on the tip of the sword and performed a powerful sword technique to completely destroy the shadow creatures.

"Lin Feng, your magic skills have improved again." Li'er said with a smile.

Lin Feng smiled slightly and said, "This is all honed in battle."

Continuing to go deeper into the cave, they finally found a gem that emitted a powerful light.

"Is this the dawn we have been looking for?" Li'er said in surprise.

Lin Feng walked forward and wanted to pick up the gem, but was bounced away by a powerful force.

"It seems that there is a powerful barrier protecting this gem." said the old man.

Lin Feng frowned and began to think about how to break the barrier. He carefully observed the runes around him, trying to find a way to break it.

After some research, Lin Feng discovered the pattern of the runes. He, Li'er and the old man performed magic together to break the barrier.

Thanks to their efforts, the barrier was finally broken and Lin Feng successfully got the gem.

Just when they thought everything was over, the cave began to shake violently and countless huge rocks fell from above.

"Oh no, this cave is going to collapse!" the old man shouted.

Lin Feng pulled Li'er and rushed towards the cave entrance with the old man.

At the critical moment, they finally escaped from the cave. However, the danger in the abyss was not over.

A group of powerful demon generals appeared in front of them and blocked their way.

"Hmph, it's not that easy to leave the Demon Abyss with the Dawn!" The leading demon general sneered.

Lin Feng was not afraid at all and said, "Come on, let's see who can stop us!"

A fierce battle broke out again. Lin Feng and Li'er used their strongest magic to fight a desperate battle with the demon generals.

In the battle, Lin Feng and Li'er cooperated with each other and displayed amazing strength. The old man also constantly gave them support and guidance.

After a hard battle, they finally defeated the demon general and successfully left the Demon Abyss.

After returning to the fairyland, Lin Feng and Li Er handed the Dawn to the elders of the fairyland. Their heroic deeds spread throughout the fairyland, and they became heroes admired by everyone.

However, Lin Feng knew that this was only a small victory on their journey to immortality, and there would be more challenges waiting for them in the future.

Li'er looked at Lin Feng and said, "Brother Lin Feng, no matter how difficult the future is, I will always be by your side."

Lin Feng smiled and nodded, saying: "Well, let's move forward together."

From then on, Lin Feng and Li'er continued on their journey to immortality. In order to protect the peace and tranquility of the immortal world, they continued to practice hard and meet new challenges.
