Rise of the Otherworld.

The violent tremors coming from deep within the cave made everyone's nerves, which had just relaxed, tense up again. The ground shook incessantly, and rocks fell from overhead from time to time, hitting the ground with a dull thud.

"What the hell is going on?" The man in black robe stood up with difficulty, his face covered with dust and sweat. His clothes were already tattered in the previous battle, and now he looked even more miserable.

The old man frowned and said worriedly, "I'm afraid our fight just now triggered some mechanism, causing a more powerful crisis." There was a hint of regret and helplessness in his voice.

The herbalist was terrified and asked in a trembling voice, "What should we do then?" His eyes were full of fear and confusion, and his hands were tightly grasping his package, as if it was his last straw.

At this moment, the mysterious force that had sucked Zhang Hao away surged again, growing even stronger. In the darkness, an invisible pressure made it almost impossible for everyone to breathe, as if a giant hand was tightly gripping their throats.

"Oh no, this mysterious power seems to be awakening!" exclaimed the man in black robe, his face turned pale in an instant, and beads of sweat fell from his forehead like rain.

As his power grew, the light within the cave began to distort, and the surrounding scenery grew blurry. The once solid stone walls began to seem ethereal, swaying like reflections in water.

"Everyone, come closer, don't get separated!" the old man shouted loudly, his voice was particularly loud in the trembling cave.

Everyone huddled together, their hearts filled with fear and anxiety. Their bodies trembled slightly from nervousness, but their eyes revealed a firm determination.

Suddenly, a powerful light shot out from the depths of the cave, illuminating the entire space. The light was as dazzling as the sun, and everyone was blinded by it.

When they regained their sight, they discovered a vast rune array before them, shimmering with light and mysterious. The runes, like swirling snakes, constantly shifted shape and position, creating a dazzling display.

"Is this the source of the mysterious power?" the herbalist asked in a trembling voice, his eyes wide open, filled with astonishment and fear.

Before anyone could answer, a powerful suction force came from the rune array, sucking everyone in.

After a dizzying spin, they arrived in an unfamiliar space. Thick fog stretched all around, seemingly endless. The mist, thick as milk, made them feel as if they were in a dream.

"Where is this?" The man in black robe looked around vigilantly, holding magic tools tightly in his hands, ready to deal with any possible danger at any time.

At this moment, an illusory figure appeared before them. The figure was looming and seemed to disappear in the mist at any moment.

"You intruders, how dare you touch the forbidden power!" The figure uttered a majestic voice, which echoed in the space, making everyone's ears buzz.

Everyone was startled and prepared to fight. Their eyes were determined, and they showed no sign of retreat.

"Who are you? Why are you stopping us?" the old man asked loudly, with a hint of anger and confusion in his voice.

"I am the guardian of this power, and your actions will bring disaster!" said the figure, its tone cold and ruthless, leaving no room for negotiation.

"We are just trying to find the truth and save the town!" Zhang Hao's voice suddenly came.

It turned out that Zhang Hao had also been sucked into this space. He had a determined look on his face, staring straight at the figure.

"Hmph, ignorant humans, you don't know what you are doing at all!" said the guardian, its figure trembling slightly, as if suppressing its inner anger.

Zhang Hao stepped forward and said fearlessly, "No matter what, we will not retreat!" His voice was firm and powerful, and it was particularly clear in the foggy space.

The Guardian was silent for a moment, seemingly contemplating something. Then, it slowly said, "If that's the case, then you should accept the test. If you can pass, there might still be a glimmer of hope..."

As soon as he finished speaking, the surrounding fog began to surge, forming huge whirlpools. From the whirlpools, terrifying roars continued to be heard, as if countless monsters were about to rush out.

Everyone's expressions became more solemn. They knew that a more difficult challenge was about to come...
