Rise of the Otherworld.

Lin Yu felt something moving under his feet, and his heart tightened, but he didn't dare to move. He tried to steady himself and try to see what it was. The poisonous fog around him became thicker and thicker, greatly obstructing his vision. He could only rely on his senses to deal with the impending danger.

At this moment, the thing suddenly rushed out. It turned out to be a huge crocodile. The crocodile opened its bloody mouth, its sharp teeth flashing with cold light, and bit towards Lin Yu. It was as fast as lightning, with a killing momentum.

Lin Yu reacted quickly, drew his sword, and stabbed the crocodile fiercely. The blade collided with the crocodile's hard scales, creating a string of sparks. The crocodile roared in pain and dove into the swamp, but it did not go far away, still watching around.

"Master, be careful!" the disciples behind him shouted anxiously. Their voices were a little blurry in the poisonous fog, but they were full of concern and worry.

Lin Yu gritted his teeth and continued to move forward with difficulty. Every step took a lot of effort, and if he was not careful, he might fall into a deeper quagmire. The muddy water in the swamp had already covered his knees. Every time he lifted his legs, they felt extremely heavy, as if countless hands were pulling him from below. Moreover, the poisonous mist made him feel short of breath and dizzy. Every breath was like inhaling a burning flame, burning his lungs.

"Everyone, wait for me to find out the route before following!" Lin Yu shouted loudly. His voice was a little hoarse due to fatigue, but still firm and powerful.

Xiaoyaozi shouted from behind: "Master, be careful!" His eyes were full of anxiety, and he stared at Lin Yu's figure closely.

Lin Yu moved forward step by step. Suddenly, his feet slipped and he sank down. The muddy water instantly submerged his waist, and the strong suction made him unable to extricate himself.

"Not good!" he cried in his heart. Fear instantly surged into his heart, but he quickly forced himself to calm down.

He struggled desperately, trying to grab something to stop himself from sinking, but there was nothing around him except mud and water. Despair spread in his heart, but he told himself not to give up. Just when he was about to despair, he touched a thick branch. The branch seemed to be a life-saving straw. Lin Yu grabbed the branch tightly, using all his strength, and the veins on his arms bulged. Finally, he pulled himself out of the mire.

He was exhausted, breathing heavily, sweat and mud mixed together, flowing down his cheeks. But he still didn't dare to stop, and continued to grope forward. Every step was full of hardship and danger.

Finally, Lin Yu found a relatively solid place. He shouted excitedly to the back: "You can come over now, follow the route I took!" There was a hint of joy and hope in his voice.

The disciples stepped into the swamp cautiously and followed Lin Yu's instructions. Their steps were slow and cautious, and their heartbeats were particularly clear in the silent swamp.

But at this moment, the crocodile reappeared and pounced on a disciple. The disciple's eyes widened in fear and for a moment he forgot to dodge.

"Be careful!" Lin Yu shouted. His voice was like thunder, instantly bringing the disciple back to his senses.

The disciple tried to dodge, but it was too late. At this critical moment, Lin Yu flew over and pushed the disciple away.

The crocodile missed its attack and became even more angry, turning around and pouncing on them again.

Can Lin Yu and his disciples successfully repel the crocodiles and pass through this swamp smoothly?
