"Tap, tap, tap..."
Suddenly, a few quick footsteps reached Gu Sheng’s ears.
"Who is it!"
Gu Sheng immediately tensed up, rushing directly toward the direction of the footsteps.
As Gu Sheng approached, he unexpectedly saw a crouching shadow.
"Swish!"
Gu Sheng summoned the Fire Spirit Dagger, ready to slay the shadow in the night.
"Boss! It’s me... it’s me!"
Suddenly, Gu Sheng heard a familiar voice.
By the faint light of the Fire Spirit Dagger, Gu Sheng recognized the person’s face.
"Tu Fei? Why... why are you down here too?"
Gu Sheng was speechless, putting away the Fire Spirit Dagger.
"I’m... I’m fine, just wandering down to see how you guys are doing?"
Tu Fei smiled awkwardly as he spoke.
"Tch!"
Gu Sheng sighed lightly, "You better go up quickly, things are not looking good here, hurry!"
Saying this, Gu Sheng began to push Tu Fei toward the exit.
But Tu Fei sidestepped and said with a smile, "Don’t push me, I can walk by myself."
"Cough, cough..."
Suddenly, a coughing sound came from Elder Li Yuan’s side.
"Quick! Get up there!"
Gu Sheng coldly ordered.
Tu Fei smiled and said, "Okay, as long as you’re all right, I’ll head up now, okay."
Saying that, Tu Fei walked straight toward the exit.
Meanwhile, Gu Sheng quickly returned to Elder Li Yuan’s side, fearing that something might have happened there.
When Gu Sheng returned to Elder Li Yuan’s side, he saw that Li Yuan’s complexion had improved greatly.
It seemed he had managed to expel the purple-blue flame from his body.
At this moment, his eyes were much brighter, indicating he had recovered about seventy percent.
"The protective power of this Earth Core Tower is stronger than I imagined, we can’t act rashly, we must come up with a strategy."
Elder Li Yuan exhaled slightly as he spoke.
"Mm."
Gu Sheng nodded and then helped Elder Li Yuan up.
At this moment, Gu Sheng was also filled with concern, scanning his surroundings, trying to find some clues.
Perhaps there’s a way for them to safely pass through this passage.
Just then, Gu Sheng’s gaze landed on the walls of the passage.
He discovered some strange patterns on the walls, resembling the shape of the purple-blue flames.
"Elder, look at these patterns, they seem to be telling us something."
Gu Sheng said, pointing at the patterns on the wall.
Elder Li Yuan walked over, sweeping his gaze over the patterns.
And with this glance, Elder Li Yuan’s eyes also showed surprise.
"These patterns are the rune power of the Earth Core Tower. It seems the purple-blue flame didn’t appear without reason, but is related to these runes."
Suddenly, a rumbling sound came.
Subsequently, the entire mine began to shake violently.
Elder Li Yuan’s face turned pale, and he immediately shouted, "Not good, the mine is about to collapse, run!"
After saying that, Gu Sheng and Elder Li Yuan rushed toward the exit.
In less than a minute, Gu Sheng and Elder Li Yuan barely managed to escape the mine.
As they rushed out together, behind them was a scene of chaos and roaring.
In an instant, the mine completely collapsed, turning into a basin.
Dust rose, blotting out the sky.
The entire Area Thirteen fell into a deathly silence.
Gu Sheng was filled with panic, suddenly recalling Tu Fei’s image in his mind.
He anxiously looked around, shouting Tu Fei’s name loudly, "Tu Fei! Tu Fei! Where are you?"
At this moment, Old Li hurriedly ran over, panting.
"Xiao Sheng, don’t worry, Tu Fei ran out in a panic before the mine collapsed."
Gu Sheng was stunned, hurriedly asking, "Where is he now? I didn’t see him?"
As Gu Sheng asked, in truth, he was worried that Tu Fei had not left the mine at all and had secretly collected the refined ore.
Old Li shook his head, "He doesn’t seem to be injured, but... he said he seems to have taken a piece of refined ore."
"What did you say! Refined ore?"
Gu Sheng was suddenly shocked.
By the side, Elder Li Yuan’s face also changed drastically upon hearing this, "Refined ore? How could he do that! That mine might have been supported by the refined ore! Taking the refined ore was a huge mistake!"
Gu Sheng furrowed his brow tightly, a wave of unease in his heart.
