Taking advantage of the opportunity, Ning Yu led Mu Xue to break through the encirclement and arrived at Wang Meng's side, asking with concern, "How are you?"

Wang Meng's face was pale, and large beads of sweat rolled down his forehead, but he still gritted his teeth and persevered, "I can still hold on, you guys go quickly..."

Before he could finish speaking, his body suddenly swayed, his eyes rolled back, and he collapsed to the ground unconscious.

"Wang Meng!" Ning Yu quickly supported him and channeled a wisp of energy into him, but Wang Meng remained unconscious, clearly due to overexertion of his superpowers.

"Don't worry about me, hurry up..." Mu Xue struggled to her feet, pointing towards the depths of the cave, "The Overlord is just ahead, we can't let it get away!"

Ning Yu looked at the unconscious Wang Meng and the injured Mu Xue, a flicker of hesitation crossing his eyes, but ultimately he gritted his teeth and made his decision. He handed Wang Meng over to the other team members to care for, then helped Mu Xue up, his gaze resolute as he looked into the depths of the cave, "Let's go!"

They knew that the battle was not over yet, and even greater challenges lay ahead. Passing through the passage cleared by lightning, they came to a massive metal door, which shimmered with an eerie light.

"This is the lair of the Overlord..." Ning Yu felt a powerful energy fluctuation emanating from behind the door, making his heart pound. He took a deep breath, placed his hand on the metal door, and mobilized all his energy, trying to force his way through. However, the metal door remained unmoved, like an insurmountable chasm blocking their path.

"No, my strength is not enough!" Ning Yu's face was pale, and fine beads of sweat appeared on his forehead.

"Let me do it!" Despite the excruciating pain, Mu Xue walked to Ning Yu's side and placed her hand on his. "Let's do it together!"

The two forces converged, and the light on the metal door began to become unstable, emitting a hissing sound, as if it were about to collapse at any moment.

"Just a little bit more!" Ning Yu felt hope was within reach. He mustered his last bit of strength, united everyone's will, and roared, "Break!"

"boom--"

With a loud crash, the metal door swung open, and blinding light poured out from behind it, engulfing their figures.

Ning Yu and Mu Xue shielded their eyes from the blinding light and slowly opened them. The sight before them stunned them... As the blinding light gradually dissipated, Ning Yu and Mu Xue finally saw clearly what was before them. What appeared before them was not the lair of the Overlord as they had imagined, but a vast and boundless space.

This space seemed to exist independently outside the cave, without cramped rock walls or sticky liquids, only emptiness. Yet, within this emptiness, countless points of light flickered like fireflies, emitting a soft glow that illuminated the entire space, making it appear as dreamlike and enchanting.

"Where is this place..." Mu Xue was shocked by the scene before her and murmured to herself.

Ning Yu looked around, his brows furrowed. He tried to sense the energy fluctuations around him, but found that his special ability seemed to have lost its function here, and he was completely unable to detect any information.

"Be careful, something's not right here," Ning Yu whispered a warning, his gaze sweeping over the unconscious team members, a sense of unease rising within him. Wang Meng and the other team members had exhausted their supernatural abilities to break through the previous lightning zone and were still unconscious. If there were any hidden dangers here, the consequences would be unimaginable.

"Should we go back?" Mu Xue also noticed something was wrong, gripped her weapon tightly, and asked in a low voice.

“It’s still uncertain whether this place is safe, and…” Ning Yu’s gaze fell into the depths of the space, where a huge spherical building could be vaguely seen, radiating a dazzling light. “The Overlord is very likely there.”

“But…” Mu Xue wanted to say something, but Ning Yu interrupted her.

“I know what you’re worried about, but we’ve come this far, we can’t give up halfway.” Ning Yu took a deep breath, his eyes hardening. “Trust me, I will protect everyone.”

As he spoke, he bent down, intending to carry an unconscious team member on his back. However, the instant his hand touched the team member's body, a scorching energy suddenly surged from his fingertips, as if he were being burned by a raging fire. The intense pain made him gasp involuntarily.

"What's wrong?" Mu Xue asked, and quickly stepped forward to help him up.

“This light… is strange!” Ignoring the pain, Ning Yu looked up at the seemingly soft points of light, his eyes filled with vigilance.
