Chapter 223: Escape from the Fantasy World: Lin Xiao and Mo Yu's Speed ​​of Life and Death

Lin Xiao and Mo Yu were trapped in the eerie castle. The fog around them seemed to have life, constantly wriggling, making people feel as if they were in the stomach of a giant monster. The walls of the castle were covered with wet moss, which was dark green and exuded a disgusting smell of decay.

Lin Xiao's face was as pale as paper, her lips kept trembling, her hands tightly grasped the sword, and her voice trembled like a leaf in the wind: "Mo Yu, this place is simply a ghost cave, I feel like my heart is about to be crushed by fear! Can we really find a way out?"

Mo Yu's eyes were as firm as iron. He stared straight ahead, as if he could penetrate the thick fog. He said in a steady and powerful voice, "Don't be afraid, Xiao'er. I'm here. Even if it's a sea of ​​fire and a mountain of swords, we can get out!"

They groped their way forward cautiously in the castle. With every step they took, the stone slabs under their feet made a dull "creaking" sound, as if telling them the ancient secrets of the castle.

Suddenly, a sinister laughter echoed in the empty hall like a ghostly scream. The laughter was so sharp and piercing that it seemed to pierce their eardrums.

"Hahahaha, don't even think about leaving here alive! This is a death trap, it's your grave!"

Lin Xiao was frightened by the sudden laughter and trembled all over. Her eyes were wide open, full of fear and panic, and her voice changed: "Who? Who is talking? Come out if you have the guts, don't play tricks behind my back!"

Mo Yu quickly protected Lin Xiao behind him, holding the sword tightly in his hand, and looked around vigilantly, shouting: "You cunning fellow, if you have the guts, come out and fight me head-on. What kind of hero are you if you hide in the dark!"

At this moment, a dark shadow flew down from the beam like a ghost, so fast that it was almost invisible. The dark shadow was in front of them in an instant, bringing a gust of cold wind.

Lin Xiao subconsciously took several steps back. Her heartbeat accelerated rapidly, as if it was about to jump out of her throat. Her voice was full of fear: "What...what kind of monster is this?"

Mo Yu drew his sword without hesitation and faced the shadow, instantly engaging in a fierce fight with him. His sword flashed cold rays through the air, and each strike was filled with the determination to kill.

"Xiao'er, stay away! Don't let this guy hurt you!" Mo Yu shouted loudly while fighting fiercely with the black shadow.

Lin Xiao stood nervously aside, his eyes fixed on the battle situation, his hands tightly clutching the corners of his clothes, his heart in his throat.

Mo Yu's sword passed through the black shadow, but it seemed to have hit the void and did not cause any damage.

"How is this possible? What on earth is this thing?" Mo Yu was shocked and beads of sweat appeared on his forehead.

The black shadow took the opportunity to launch a counterattack. Its movements were as fast as lightning. Mo Yu was unable to dodge and was hit by the black shadow, falling heavily to the ground.

"Mo Yu!" Lin Xiao exclaimed and ran over, her face full of worry and anxiety.

At this moment, a strange sound was heard in the castle again. The sound sounded like countless footsteps or heavy breathing, which made people feel creepy.

"What is going on? Are there more monsters?" Lin Xiao's voice was filled with fear and confusion, and her body couldn't help but tremble.

Mo Yu stood up despite the pain. His eyes were still firm as he said, "Xiao'er, no matter what, we can't give up. As long as we are alive, there is hope!"

Suddenly, Lin Xiao discovered a mysterious pattern on the wall. The pattern looked like an ancient rune, or some kind of mysterious code, emitting a strange light.

"Mo Yu, look at this pattern, could it be a clue to get out?" A glimmer of hope flashed in Lin Xiao's eyes.

Mo Yu looked at the pattern, frowned, and fell into deep thought: "This pattern... seems to hide some mystery."

As they studied the pattern, the shadow attacked again, faster and more powerful than before.

"Be careful!" Mo Yu shouted loudly and swung his sword towards the black shadow again.

Lin Xiao was not idle either. She was watching the battle nervously while trying to think about the secret of the pattern.

"What does this pattern mean? I must solve it!" Lin Xiao bit his lip and said to himself.

At this time, the fog in the castle became thicker and thicker, and the temperature around them dropped sharply, as if they had fallen into an ice cellar.

"This damn fog, I can't see anything!" Mo Yu cursed, but the sword in his hand did not stop.

Lin Xiao suddenly had an idea: "I think I understand! This pattern is an ancient formation!"

"Really? Then let's crack it quickly!" Mo Yu said while resisting the attack of the black shadow.

Lin Xiao began to decipher the pattern according to her own understanding. Her fingers moved quickly on the pattern, and beads of sweat kept rolling down her forehead.

Just when Lin Xiao was about to crack the pattern, the black shadow noticed their intention and pounced towards Lin Xiao frantically.

"Not good!" Mo Yu risked his life to stand in front of Lin Xiao.

"Mo Yu!" Lin Xiao screamed.

At the critical moment, Lin Xiao successfully cracked the pattern. A ray of light flashed, and everything in the castle began to change...
