Rise of the Otherworld.

After hearing the old man's reminder, everyone's spirits rose. Although their bodies were already exhausted, as if their bones and muscles were pulled out, and every muscle was sore and protesting, their desire to survive and their persistence in justice made them cheer up and prepare to make an all-out effort.

Zhang Hao took the lead in launching the attack. He poured his spiritual power into his longsword without reservation. For a moment, the longsword shone brightly, like a dazzling star. And he rushed towards the black-robed guardian as swiftly as an arrow from a bow. This time, his eyes were as firm as iron, his target was clear, and he went straight for the black-robed guardian's left hand. The black-robed guardian snorted coldly, and the sound seemed to be squeezed out from between his teeth, full of disdain. He casually waved his right hand, and a black light curtain as thick as ink instantly blocked in front of him. Zhang Hao's longsword pierced the light curtain fiercely. In an instant, a burst of dazzling sparks splashed out, like a gorgeous firework blooming in the night sky, but the light curtain was like an indestructible wall, and the longsword could not break through it at all.

Ling Yu seized the opportunity to swerve from the side. His movements were as ethereal as a ghost, and he silently approached the black-robed guardian. His eyes fixed on the guardian's every move, and when the time was right, he thrust the dagger in his hand like a venomous snake, stabbing the guardian's left hand fiercely. The guardian, sensing Ling Yu's movements, tried to dodge, but Zhang Hao's restraining force slowed him down. With a swish, the dagger grazed his left hand, slicing through his sleeve and leaving a trail of blood that stood out against the darkness.

"You ant!" the black-robed guardian roared, the sound like a crackling thunder, shaking the surrounding air. A fierce gleam flashed in his eyes, like two balls of burning blood-red flames. With a wave of his left hand, a black flame, accompanied by a surging heat wave, pounced fiercely at Lingyu like a roaring beast. Lingyu was unable to dodge and was hit head-on by the flames. As if struck by lightning, his body flew backward uncontrollably, tracing an arc in the air and landing heavily on the ground, splashing a cloud of dust.

"Lingyu!" The woman saw this, her heart aching, her beautiful face contorted with worry. Her hands formed hand seals as quickly as a phantom, muttering something as she unleashed a powerful freezing spell. Instantly, a crystal-clear wall of ice rose before Lingyu, like a solid fortress, blocking the ensuing surging flames. Simultaneously, she condensed countless sharp ice cones, which gleamed coldly in the moonlight and rained down upon the black-robed guardian like a torrential rain.

The black-robed guardian had to devote his energy to dealing with the ice cones. He danced his hands wildly, and black energy formed a huge vortex in front of him. The vortex seemed to be an endless black hole, sucking the ice cones into it, crushing them in an instant, and turning them into pieces of ice chips floating in the air.

While the black-robed guardian was dealing with the icicles, the mysterious man took a deep breath. Though the pain from the breath ripped through his body, he gritted his teeth and cast another spell. A golden light emanated from his hand, gathering like a torrent, transforming into a lifelike golden dragon. The dragon roared to the heavens, its voice echoing through the valley, threatening to burst through the clouds. Then, roaring, it charged towards the black-robed guardian.

The black-robed guardian sensed the golden dragon's immense power, his expression changing slightly. His initial disdain gave way to a hint of vigilance. He had no choice but to abandon his attack on Lingyu and focus all his energy on resisting the golden dragon. The golden dragon's black energy collided with the black-robed guardian's. For a moment, a flash of light shone, like countless stars exploding simultaneously. Energy overflowed, and the entire space seemed to be distorted by this powerful force.

At this moment, Zhang Hao, seizing the perfect opportunity, once again charged at the black-robed guardian like a tiger descending from a mountain. He channeled all his spiritual energy into his longsword, unleashing his most powerful attack. The longsword shone brightly, its light seemingly illuminating the entire dark valley, tearing through the endless darkness.

"Go to hell!" Zhang Hao shouted, his voice filled with determination and anger. With unstoppable momentum, his longsword stabbed fiercely at the black-robed guardian's left hand. The black-robed guardian was fully focused on resisting the golden dragon, unable to spare any time. He could only watch helplessly as the longsword pierced through him with lightning speed.

With a "puff," the longsword pierced the black-robed guardian's left hand, sending blood gushing out like a fountain, splashing onto the ground. The black-robed guardian roared in agony, a voice filled with rage and resentment, like a wounded beast. His left hand drooped limply, the once powerful black energy instantly weakening. The golden dragon seized the momentum, breaking through the obstacles and crashing into him like a heavy artillery shell.

The black-robed guardian flew backward like a kite with a broken string, tumbling several times in the air before crashing heavily into the main hall wall. With a resounding bang, spiderweb-like cracks appeared on the wall, dust flew everywhere, and the entire main hall trembled.

Everyone was on guard, their weapons tightly gripped, their eyes fixed on the black-robed guardian. He slowly stood up, his black robe tattered and fluttering in the wind. His face was filled with ferocity and anger, as if he wanted to cut everyone into pieces.

"You've succeeded in angering me. I'll make you pay dearly!" the black-robed guardian grumbled, each word seemingly squeezed from between his teeth. The black mist surrounding him grew thicker, like billowing smoke. An even more powerful aura emanated from him, filling everyone with an unprecedented sense of oppression, as if an invisible mountain were bearing down on their hearts...
