"Ning Yu!" Mu Xue used all her strength to crawl to Ning Yu's side and support him. She looked at him through teary eyes, her heart breaking.

Ning Yu leaned weakly against Mu Xue, forcing a smile: "It's okay... I'm fine..."

Mu Xue forced back her tears and began searching around the cave for something that could be used to reinforce it.

She found some pebbles and dry branches, which she used to reinforce the cave walls to prevent them from being buried by sandstorms.

The wind and sand were still howling, but the cave was relatively safe.

Ning Yu leaned against Mu Xue's chest and gradually regained some strength.

He watched Mu Xue's busy figure, his heart filled with gratitude and guilt.

"Thank you, Mu Xue..."

Mu Xue stopped what she was doing, looked at Ning Yu, her eyes filled with worry: "Don't talk nonsense, we'll all get out of here."

They all knew that this was only temporary safety.

Unknown dangers await them at the source of the wind, and they must continue forward.

Ning Yu took a deep breath and slowly stood up, supporting himself against the cave wall.

“Let’s go,” his voice was weak but firm. “We can’t wait here to die.”

Mu Xue nodded and stood up as well.

She helped Ning Yu walk step by step towards the cave entrance.

The sandstorm hit them again, and the biting cold made them shiver.

“Wait…” Mu Xue suddenly stopped in her tracks. Her gaze fell on a rock at the cave exit, where something seemed to be carved.

She stepped forward and examined it carefully… “This…this is…”

Mu Xue brushed the sand and dust off the rock, revealing a blurry pattern, like a spiral symbol. "This... seems to be some kind of mark."

Ning Yu leaned closer to observe, his brows furrowed.

“I’ve never seen this symbol before.” He reached out and touched the cold rock, feeling its rough texture, and a strange unease welled up inside him.

"Could it be left behind by those creatures from before?" Mu Xue's voice trembled slightly as she recalled the terrifying creatures she had encountered before, still feeling lingering fear.

Ning Yu shook his head. "No, those creatures are more like wild animals; they wouldn't leave such regular patterns." He looked around. The sandstorm gradually subsided, and a faint glimmer of light appeared in the dim sky.

“We need to get out of here as soon as possible; this place makes me feel very uncomfortable.”

They helped each other out of the cave, and the biting cold wind swept in again, stirring up the sand and dust on the ground and forming swirling sand pillars.

Ning Yu released his special ability again, forming a thin energy barrier to resist the invasion of the wind and sand.

"It seems this sandstorm is almost over." Mu Xue squinted, gazing into the distance, where she could vaguely see some twisted building ruins.

Ning Yu nodded. "I hope so." He felt that his supernatural power was being greatly depleted. The burst of power just now had almost exhausted his energy, and he urgently needed to replenish his energy and rest.

They moved forward slowly, each step incredibly difficult.

Although the sandstorm had subsided, visibility remained very low, and they could only rely on each other's senses to grope their way forward.

After walking for a long time, the sandstorm finally stopped completely, and the sky gradually cleared up.

Ning Yu and Mu Xue recovered from the sandstorm and continued on their way. Suddenly, Ning Yu stopped. He smelled an unusual odor, a pungent, chemical-like smell.

"Wait, do you smell something?"

Mu Xue stopped and took a deep breath. "What's that smell? It's a bit pungent..." Before she could finish speaking, a thick fog appeared ahead and slowly drifted towards them.
