Rise of the Otherworld.

Hearing his disciples' cries, Lin Yu rushed without hesitation towards the lighter-colored area on the monster's abdomen. His movements were as swift as lightning, his sword raised high, his momentum unwavering. The blade gleamed with a cold light, as if a manifestation of his unwavering conviction. His eyes were focused and resolute, and every step he took was filled with strength and determination.

The monster seemed to have sensed Lin Yu's intention and waved its arms wildly, trying to stop him from approaching. The thick arms made a whirring sound, and every swing seemed to tear the air.

"Everyone, protect the master!" Xiaoyaozi shouted, leading his disciples to cast various spells. For a moment, light shone brightly, like a dazzling firework. Some disciples cast the Fireball spell, sending huge fireballs flying towards the monster; others used the Ice Cone spell, firing sharp ice cones at the monster like a rain of arrows.

Lin Yu, under the protection of his disciples, approached the monster with difficulty. His clothes were torn by the monster's attack, revealing bloodstains. Blood flowed out from the wounds, staining his clothes red, but he seemed to feel no pain, his eyes always fixed on the monster's weakness.

When he was only a few steps away from the monster, it suddenly opened its mouth and spewed out a stream of black flames. The flames were so hot that they seemed to be able to reduce everything to ashes.

Lin Yu dodged sideways, but was still swept by the edge of the flame. He felt a sharp pain, as if being bitten by thousands of ants. But he gritted his teeth and endured it. The veins on his forehead bulged and sweat fell like rain. Taking advantage of the gap between the monster's attacks, he rushed forward in one step.

"Break it!" Lin Yu roared, thrusting his sword fiercely into the monster's weak spot on the abdomen. His arm muscles were tense, and he used up all his strength.

The moment the sword touched the monster, a strong resistance came. It felt like stabbing into hard steel, unable to move forward at all. But Lin Yu did not give up. A trace of determination flashed in his eyes, and he pushed the sword in with all his strength.

Finally, the sword penetrated the monster's defense and stabbed deep into its abdomen. Black blood gushed out like a fountain, splashing all over Lin Yu.

The monster let out a shrill scream, and its entire body trembled violently. Its cry was deafening, shaking the entire castle. It struggled madly, and the huge force threw Lin Yu out.

Lin Yu fell heavily to the ground and was unable to get up for a while. He felt a blackout in front of his eyes and the world was spinning.

"Master!" the disciples shouted anxiously, their voices filled with worry and concern.

After being wounded, the monster became even more ferocious. Its eyes turned even blood red, filled with endless rage and murderous intent. It launched a desperate final attack on everyone, its massive body like a moving mountain, bringing a tremendous sense of oppression.

The disciples fought desperately, but their strength gradually wore thin. The prolonged battle had drained them of energy, and the radiance of their magic dimmed. Some disciples, struck by the monster's attacks, vomited blood and collapsed to the ground; others, drained of their spiritual power, collapsed on the ground, unable to fight any longer.

The situation is becoming increasingly critical, as if the end of the world is approaching.

Lin Yu endured the pain and stood up again. His legs trembled slightly, but his spine remained straight.

"Hold on, everyone!" he shouted, his voice hoarse but full of power.

Can they defeat the monsters and escape from this desperate situation? Or will they be buried forever in this gloomy castle?
