Rise of the Otherworld.

The group of monsters, formed from spiritual energy, lunged at them with fangs and claws bared, closing the distance between them in an instant. The wolf-like monster in the lead opened its bloody mouth, and a stream of black spiritual energy spurted out from it, like a black lightning, swiftly attacking Zhang Hao.

Zhang Hao's eyes flashed, and he swung his sword rapidly, forming a blue spiritual barrier before him. The black spiritual energy collided with the blue barrier, unleashing a burst of intense light and overflowing spiritual energy. Zhang Hao was thrown back a few steps by the impact, but he quickly regained his balance and pointed his sword at the wolf. A blue light shone brightly, and he unleashed the "Sea Breaking Waves" move. A massive wave suddenly appeared, surging towards the wolf with the force of a tsunami.

The wolf, undaunted, kicked its hind legs and leaped high, dodging the impact of the waves. Then, it twisted in mid-air, like a black meteor, pouncing once more at Zhang Hao. Meanwhile, other monsters also launched their attacks. A python-like monster twisted its body, stealthily approaching from the side, poised to deliver a fatal blow to Zhang Hao; a bird-like monster circled in mid-air, waiting for an opportunity to swoop down.

Seeing this, Lingyu immediately cast a wind spell. He quickly formed hand seals, muttering something, and a gust of wind rose up. Like an enraged beast, the wind swept towards the monsters. The smaller monsters were thrown here and there by the wind, their formation thrown into disarray. Seizing this opportunity, Lingyu condensed several wind blades, which shimmered with a cyan light and shot towards the monsters like sharp flying knives.

The mysterious man wasn't idle either. He manipulated his earth-based spiritual energy, creating several sharp stone pillars that rose from the ground. The pillars suddenly appeared from beneath the monsters' feet. Some monsters, unable to dodge, were pierced by the pillars, dissipating into a ball of spiritual energy. However, many monsters nimbly avoided the pillars' attacks and continued to pounce on the crowd.

The woman swung her ice sword, causing the surrounding temperature to plummet. She created a vast icy sphere centered around herself. Within this sphere, countless ice spikes appeared from thin air, shooting towards the monsters like a swarm of silver arrows. The ice spikes carried a biting chill, and once struck, the monsters' movements became sluggish.

The old man swung his staff, unleashing streams of flame. The flames, crimson red, resembled dancing dragons, weaving through the horde of monsters. Wherever the flames touched, the monsters roared in agony. Yet, these monsters seemed tireless, charging at the crowd one after another.

Zhang Hao knew this wasn't going to work; he had to find the monsters' weaknesses quickly. While dealing with the wolf, he observed the other monsters' movements. He noticed that whenever a monster was attacked, its spiritual energy would flicker, especially around its heart, where the light flickered most noticeably.

"Attack their heart, that's their weak point!" Zhang Hao shouted loudly, his voice still clearly audible amid the fierce battle.

Upon hearing this, everyone immediately adjusted their attack strategy. Ling Yu concentrated his strength, condensing a massive wind blade and slashing it towards the wolf's heart. The wolf, sensing the deadly threat, attempted to evade, but Zhang Hao, seizing the opportunity, stabbed it in the leg with his longsword, halting its movement. The wind blade descended with the force, striking the wolf's heart with pinpoint accuracy. The wolf let out a scream and dissipated into a ball of black spiritual energy.

The mysterious man manipulated a thick stone pillar and rammed it towards the python's heart. The python tried to dodge, but the woman, seizing the opportunity, fired an ice arrow from her ice sword, striking the python in the head and briefly stunning it. The stone pillar then struck the python's heart, causing it to dissipate.

Under the combined attack of everyone, the monsters were gradually eliminated. A faint mist of spiritual energy filled the secret room, and everything finally returned to peace...
