Rise of the Otherworld.

The mechanical monster roared and charged toward them. With every step, the ground trembled, stirring up clouds of dust. The roar reverberated like thunder in the enclosed space, jarring everyone's eardrums. The monster's massive body resembled a moving mountain, its metal shell gleaming with a cold sheen in the dim light, a chilling sensation.

Seeing this, Zhang Hao shouted, "Everyone, spread out! Find its weakness!" His voice was decisive and resolute, radiating fearless courage. Before he finished speaking, he charged at the monster like an arrow from a bow, sword raised high, a faint light flickering on its blade, as if reflecting his unwavering conviction.

Everyone quickly dispersed, each looking for a chance to attack. Zhang Hao rushed the monster head-on, sword raised high, and slashed at its legs. His movements were swift and fierce, the wind whistling from his sword, carrying the momentum of a bamboo-breaking blow.

The monster reacted quickly, raising its massive leg and delivering a powerful kick, sending Zhang Hao flying. Zhang Hao's body slammed into the wall like a cannonball, making a dull thud. He felt as if his internal organs had shifted, a sweetness welled up in his throat, and a trickle of blood oozed from the corner of his mouth.

"Zhang Hao!" the herbalist exclaimed. His voice was filled with concern and anxiety, and his eyes were filled with worry.

The black-robed figure took the opportunity to circle behind the monster and launch an attack, but his weapon slashed against the monster's hard shell, leaving only a shallow mark. Sparks flew, and the black-robed figure's arm went numb from the recoil, but he gritted his teeth and swung his weapon again, constantly trying to break through the monster's defenses.

The old man swung his staff and cast a spell. The light struck the monster's head, but failed to cause any substantial damage. The light from the spell dissipated on the monster's metal shell, like a short-lived firework in the night sky.

The monster turned and pounced towards the black-robed man, opening its bloody mouth and spewing out a stream of flames. The flames were so hot that they instantly ignited the surrounding air, forming a sea of ​​fire.

The black-robed man dodged the attack narrowly, a corner of his clothing being singed by the flames. His face was covered in sweat, and his hair was frizzled from the heat, but his eyes remained firm, showing no sign of retreat.

Zhang Hao got up from the ground, wiped the blood from the corner of his mouth, and rushed forward again. His eyes were full of determination and unyielding. "You beast, I won't let you succeed!" His voice was filled with anger and determination, as if he was pouring all his strength into this one attack.

Enraged by Zhang Hao's attack, the monster attacked them even more frantically. Its claws swung, stirring up gusts of wind; its tail swung across the air, as ferocious as a giant python.

The herbalist anxiously searched for the monster's weakness. Suddenly, he spotted a lighter-colored area on its belly. "Attack its belly!" the herbalist shouted. His voice shrill with nervousness, and the veins on his forehead bulged.

Zhang Hao heard the shout and leaped up without hesitation, using all his strength to thrust his sword into the monster's abdomen. His body arced through the air, and the sword pierced straight into the monster's body.

This time, the sword penetrated deeply into the monster's body. The monster roared in pain and struggled to fight back. Its movements became more violent, destroying the surrounding walls and ground beyond recognition.

Seeing this, the old man and the black-robed man launched their strongest attacks, and rays of light and power converged on the monster. The light intertwined together, forming a powerful force that impacted the monster's body.

Finally, the monster fell to the ground, motionless, its body hitting the ground hard, raising a cloud of dust.

Everyone collapsed to the ground, breathing heavily. Their bodies were exhausted to the extreme, but their eyes revealed the joy of victory.

"It's finally resolved," the black-robed man said. His voice was weak and hoarse. He lay on the ground, staring at the ceiling, as if he had exhausted all his strength.

Zhang Hao stood up and said, "We can't relax yet, let's keep moving forward." Although his body was very tired, he knew that their mission was not yet completed.

They continued to explore the ruins, taking every step with extreme caution. The stone slabs on the ground were uneven, and the shadows on the walls seemed to hide unknown dangers.

At this moment, a huge secret room appeared in front of them, with the door half-open. A mysterious aura seeped out from the crack of the door, making people feel both curious and frightened.

"What's inside?" the herbalist asked. His voice trembled, and his steps stopped involuntarily.

Zhang Hao took a deep breath and said, "No matter what it is, we have to go and see it." His eyes were firm and he walked towards the secret room without hesitation.

They walked into the secret room and saw a huge crystal ball inside, shining with a strange light. The light was colorful and constantly changing shape and color, as if it contained endless mysteries.

"What is this?" The man in black robe walked forward and wanted to touch the crystal ball.

"Be careful!" The old man stopped him, but it was too late...
