Genshin Impact.

Lin Feng and the others stood in front of the mysterious sarcophagus, their hearts full of doubts and vigilance. The old man looked at the sarcophagus and said solemnly: "The world in this coffin may hide many dangers, but it may also hide endless secrets and opportunities."

Lin Feng took a deep breath, gripped his sword tightly in his hand, and said with a firm look in his eyes: "Now that we are here, we must find out what's going on no matter what." Amber and Li'er also nodded in agreement.

Lin Feng slowly pushed the lid of the sarcophagus, and an ancient and decayed smell came to his face. As the lid moved little by little, they saw a strange light flashing inside the coffin. When the lid was completely opened, the four people were surprised to find that the inside of the sarcophagus had become a space of its own, and the light intertwined into a vortex-shaped entrance.

"It seems that this is the passage to the world in the coffin." The old man took the lead and walked towards the vortex. Lin Feng and others followed closely behind him. When they stepped into the vortex, they felt dizzy and the scene in front of them suddenly changed.

They appeared in a strange world, surrounded by a barren desert, with strong winds blowing sand and gravel, hitting their faces painfully. "Where is this?" Amber couldn't help asking.

Lin Feng looked around and found an ancient castle in the distance, looming in the desert. "Let's go to the castle first, maybe we can find some clues." Everyone headed towards the castle.

Along the way, they encountered all kinds of strange traps and attacks. Suddenly, a group of huge sandworms emerged from the sand and rushed towards them with their fangs and claws bared. Lin Feng flashed and swung his sword. In a flash, he cut the sandworm in front of him into two pieces. The old man also cast a powerful spell, shooting rays of light at the sandworms and repelling them.

Amber and Li'er were not to be outdone, and they used their unique skills to engage in a fierce battle with the sandworms. After a hard fight, they finally killed all the sandworms and continued to move towards the castle.

When they arrived in front of the castle, they found that the castle gate was closed and some strange runes were engraved on the door. The old man studied the runes carefully and said, "This is an ancient seal that we need to find a way to break."

Just as they were looking for clues, a sinister laugh came from the castle. "Haha, you ignorant intruders, now that you're here, don't even think about leaving alive."

Lin Feng said loudly: "You guys who are hiding your head and showing your tail, come out and fight if you have the guts."

"Hmph, don't be impatient. You will see me once you enter the castle." The voice disappeared after it said that.

After some exploration, the old man finally found a way to break the seal, and the castle gate slowly opened. A pungent bloody smell came from inside, making people sick. They walked into the castle carefully, and saw a huge skeleton placed in the hall, with a strange light flashing on it.

"What is this?" Amber asked.

The old man walked forward, observed for a moment, and said, "This may be the remains of some powerful creature. It seems we have to be careful."

At this moment, the skeleton suddenly moved and rushed towards them. Lin Feng and others immediately started fighting and fought a desperate battle with the skeleton. During the battle, Lin Feng found that the skeleton's weakness was in its spine. He jumped up and stabbed the skeleton's spine with his sword. With a loud bang, the skeleton fell to the ground and turned into a pile of bones.

They continued to go deeper into the castle and found an ancient book in a secret room. The book recorded the secrets of the world in the coffin. It turned out that this world was created by an ancient great man, and it hid a rare treasure, but also countless dangers and tests.

"It seems that our adventure has just begun." Lin Feng said.

At this moment, the walls of the secret room suddenly began to collapse, and countless stones fell down. They hurriedly ran out, but found that the castle was full of various monsters. They fought hard and looked for a way out surrounded by monsters.

After a hard fight, they finally escaped from the castle. However, the scene in front of them shocked them. The originally barren desert turned into a dense forest, and the forest was filled with thick fog, making it difficult to see the direction.

"The world in this coffin is so unpredictable." Amber complained.

The old man said, "Everyone be careful, this forest may not be simple."

They walked into the forest cautiously, and suddenly, a group of black figures jumped out of the woods and rushed towards them. Lin Feng looked closely and found that they were a group of werewolves. These were extremely fast and had strong attack power, which caused them a lot of trouble.

In the battle with the werewolves, Li'er was unfortunately injured. Lin Feng was extremely anxious and burst out with great strength to repel all the werewolves that besieged Li'er. The old man cast a healing spell to heal Li'er.

After a fierce battle, they finally wiped out all the werewolves. However, they also lost their way in the forest. "What should we do now?" Amber asked.

Lin Feng thought for a moment and said, "Let's find a high place first and see if we can find a way out."

They searched for a high place in the forest and finally found a mountain. They climbed to the top of the mountain and looked around. They saw a temple at the end of the forest. "Maybe that's our destination." Lin Feng said.

They headed towards the temple, encountering various dangers and challenges along the way, but they never gave up and finally arrived in front of the temple.

The door of the temple slowly opened, and a powerful force came from inside. Lin Feng and others took a deep breath and walked into the temple...
