Rise of the Otherworld.

Zhang Hao carefully touched the tiny spot with his sword. Instantly, the runes on the stone slab shone brightly. The intense light made everyone close their eyes subconsciously. A powerful wave of power emanated from the stone slab. The light was as dazzling as the sun, illuminating the entire space like daylight, making it impossible to look directly at it.

"This is..." Zhang Hao exclaimed in surprise. He felt a huge recoil from his sword, nearly causing it to drop from his grasp. His arm went numb from the shock, and he took several steps back before managing to steady himself.

The old man hurriedly shouted, "Everyone be careful, this power may be difficult to control!" His voice was anxious and nervous, and the sweat on his forehead was more obvious in the light.

Amidst the light, the runes on the stone slab began to circulate rapidly, forming a complex pattern. The pattern resembled a mysterious vortex, absorbing everything around it. The lines of the runes shimmered with a strange light, constantly twisting and deforming, dazzling the eyes.

The woman held the little girl tightly and backed away. "I don't know what consequences this will lead to." Her voice was full of worry, and her beautiful face looked a little pale because of nervousness.

The herbalist was so frightened by this sudden change that he collapsed on the ground, "Oh my God, what should I do?" His legs were weak, his eyes were full of fear, and his hands were shaking.

The black-robed man stared intently at the stone slab, seemingly contemplating a response. His expression remained impassive, but his eyes revealed a hint of focus and vigilance.

As the light grew stronger, the entire space began to tremble, cracks appeared in the surrounding walls, and debris fell, as if the end of the world was approaching.

"Oh no! This place is going to collapse!" Zhang Hao shouted. His voice was particularly sharp and full of panic in the trembling space.

The old man tried to remain calm, "Don't panic, maybe this is a necessary process to activate the eye of the formation." Although his voice was still steady, a hint of uneasiness could be heard.

At this moment, the light suddenly contracted, converging on that tiny dot. The dot instantly erupted with a powerful burst of energy, rushing towards the core. Like a flash of lightning, that energy instantly streaked across space.

Under the impact of this energy, the core roared loudly. The sound was deafening, as if the whole world was shaking.

"Did it work?" the woman asked nervously, her voice tinged with anticipation, her eyes fixed on the core.

However, before anyone could react, another beam of light shot out from the core, heading straight towards them. The light was extremely fast and carried a destructive aura.

"Get out of the way!" the black-robed man shouted, his voice filled with urgency, and he was the first to leap aside.

Everyone fled in all directions, their figures looking so small and fragile in the light.

The light passed over the place where they had just stood, leaving a deep scar. The ground was scorched and emitted a pungent smell.

"What on earth is going on?" the herbalist asked in horror, his voice tinged with tears, almost breaking down.

The old man looked at the core with a frown, "Maybe our activation method is wrong, or we are missing some steps." His eyes were full of confusion and anxiety, and his brain was working rapidly, thinking about a solution.

At this moment, the core's light began to become unstable, sometimes strong, sometimes weak. The changes in the light were like a heartbeat, making it difficult to predict.

"We can't go on like this. We have to find a solution as soon as possible," Zhang Hao said anxiously, his eyes firm and his heart filled with determination.

The little girl looked at the core and suddenly said, "I think I understand..." Although her voice was not loud, it was particularly clear in this tense atmosphere.

Everyone's eyes were instantly focused on the little girl.

The little girl continued, "I feel like the core is testing us. We need to communicate with it with our true heart."

"Really?" the woman asked doubtfully.

"Yes, we were just trying to control it with force before, without really understanding its feelings." The little girl said seriously.

Everyone fell into deep thought, thinking about the little girl's words.

Zhang Hao said, "Maybe we can try again."

So, everyone approached the core again. This time, they let go of their fear and anxiety and used their most sincere hearts to feel the power of the core...
