Rise of the Otherworld.

Everyone was shocked and looked at the mural again, but it remained as still as before.

"Little girl, did you see it wrong?" the mysterious man asked doubtfully. His face was full of suspicion and his eyes revealed a look of distrust.

The little girl shook her head firmly, "I really saw it move." Her voice was crisp and resolute, and her eyes were full of determination.

Zhang Hao pondered for a moment, "Maybe there is a mystery that we haven't discovered yet." His eyes were deep, his brows were slightly furrowed, and he fell into deep thought.

Everyone once again carefully examined the mural, not missing any details. Every line, every color was repeatedly examined by them.

At this moment, the woman discovered that there were extremely tiny grooves at the intersections of some of the lines on the mural. Those grooves were hidden in the complex patterns and would have been extremely difficult to detect if it weren't for the woman's keen observation.

"Could this be the key?" the woman asked, her voice tinged with excitement and anticipation, as if she saw hope of solving the mystery.

The old man took a closer look and said, "It's possible. Let's try injecting magic power." There was a hint of uncertainty in his tone, but he decided to give it a try.

Everyone poured their magic power into these grooves, and the mural indeed transformed. The previously static pattern began to shimmer, its light gleaming like stars, dazzling and dazzling. It then slowly shifted, forming a completely new image.

The image shows an ancient castle, tall and majestic, its walls covered in mysterious runes. A mysterious light surrounds the castle, sometimes strong, sometimes weak, as if it were breathing.

"Could this be the core of the ruins?" Ling Yu said in surprise. His eyes widened, his mouth slightly open, shocked by the scene before him.

Zhang Hao nodded, "It's very likely, we must find this castle." His tone was firm and his eyes were full of determination.

Just as they were about to study the contents of the murals further, the room suddenly began to shake violently, as if the entire room was being grasped by a giant hand and was shaking non-stop.

"Oh no, something's happening again!" the mysterious man shouted. His voice was filled with panic, and his body was shaking uncontrollably.

The wall began to crumble, and debris fell one after another. The debris hit everyone like raindrops, making a crackling sound.

Zhang Hao quickly picked up the little girl and said, "Everyone, rush out!" His voice was decisive and urgent. His figure holding the little girl rushed towards the door like a flash of lightning.

Everyone ran out of the house in a panic, their faces filled with fear and tension, their steps hurried.

As they ran out of the house, the building behind them collapsed completely, raising a cloud of dust that instantly enveloped them like a huge mushroom cloud.

"What the hell is going on?" the woman gasped. Her hair was disheveled, her face was covered in dust, and her eyes were filled with confusion and fear.

Before anyone could react, huge cracks suddenly appeared on the ground, and billowing black smoke billowed out of the cracks. The black smoke spread out, and the pungent smell made people feel suffocated.

"Be careful!" the old man shouted, his voice resounding loudly amidst the black smoke and chaos.

Everyone hurriedly retreated to avoid the crack, their steps stumbling and almost falling into it.

At this moment, the sky was covered with dark clouds, and thunder and lightning flashed. Lightning flashed across the sky, illuminating the dark world. The thunder was deafening, as if it was about to tear the whole world apart.

"Could all this be related to that mural?" Ling Yu asked. His voice was very weak amid the thunder, but it was full of doubt.

"No matter what, let's find a safe place first," Zhang Hao said. His voice was firm and powerful, bringing a sense of comfort and courage to everyone.

They struggled forward in this chaotic environment, searching for a place to hide. The ground beneath their feet kept shaking, making their steps very difficult.

Suddenly, a huge monster rushed out from the black smoke. Its body was huge, covered with sharp thorns, and its eyes were flashing red light.

"What kind of monster is this!" exclaimed the mysterious man.

Zhang Hao put the little girl down and said, "Get ready for battle!"

Everyone grasped their weapons again, ready to face new challenges...
