In the dark cave, Li Jing kept humming tunes.

In Nina's eyes, some lights flickered on and off. She looked solemn and was remembering carefully.

The humming in the little boy's mouth ended.

Nina touched her fingers and carefully recalled the sequence just now.

"The plate closest to us is Sanqi."

Li Jing understood the idea and quickly hummed it in combination with the musical scales.

The moment the voice came out of his mouth, in front of the dark cliff in front of him, a suspended stone slab close to the edge of the cliff lit up.

"Yes, that's it!"

Nina's tone was somewhat excited as she continued to explain the results of previous experiments.

"The next order is one six, three five, two two, three one——"

After writing down the specific notes that corresponded to the numbers in Nina's mouth, Li Jing began to hum in turn.

The stone slabs in front of the dark cliff lit up from near to far.

"Is it okay?"

"Um."

Li Jing responded and grabbed the rope in his hand.

"Let's go. Since you can't sing the notes accurately, leave it to me to light up the platform."

"I observed carefully just now. The corresponding function of humming is to light up the stone slab, and it will not affect the existence of the stone slab."

"Um."

Nina's slender fingers clenched the detector in her hand, looking sharply into the darkness.

I can't see the direction of Li Jing.

She frowned, pulled the cord of the detector, and gradually walked towards Li Jing.

The young boy stared intently in front of him, listening to the footsteps approaching gradually.

He hummed the note corresponding to the nearest stone brick, and the stone slab lit up.

The light illuminated the dark area, and Li Jing waved. Nina walked onto the stone slab and stretched out her hand to Li Jing.

Li Jing never stopped humming, took Nina's hand, and squeezed beside Nina.

"One six."

Nina prompted, and Li Jing quickly changed the tune after hearing this.

The stone slab under my feet went out, and the nearest, slightly higher stone slab lit up.

Nina's pupils suddenly shrank, and her face looked happy.

Go higher up, and when you first came in, the location was just underground.

Then if you walk out of the stone slab, can you return to the base?

The two climbed onto the high stone slab again.

Although the two stone slabs are adjacent to each other, there is actually half a step between them.

If you follow the illuminated area and look down through the light, you will easily find that if you take one wrong step, you will fall into a bottomless abyss.

Li Jing didn't react too much. After all, he was a veteran agent.

Although Nina was an outstanding businessman and had encountered many dangers in her business career, she still felt a moment of fear about the abyss beneath her feet.

This fear just turned into a drop of cold sweat on the forehead and had no chance to be revealed.

Following the previously confirmed order, Li Jing followed Nina's prompts and hummed to light up the slate.

The two of them followed the trend and walked to the middle. The next area was the area that they couldn't see clearly before.

The small stone slab that we settled on was not big. Fortunately, Li Jing was a young man. If there were two adults, the situation would be quite embarrassing.

An idea came to Li Jing's mind. He wondered whether the light would be swallowed up on the stone slab.

He turned on the lighting device on his arm, but the light disappeared the moment it appeared.

"It still doesn't work?"

Nina's tone was very steady.

"It's okay, let's continue trying the stone slab in front of us."

Li Jing nodded and hummed the tune as before, but the situation in front of him was not optimistic.

Nina stared at the stone slabs around her with disbelief in her eyes.

how so?

The stone slab beneath his feet suddenly began to sink slowly while Li Jing was humming.

"Why?"

Li Jing also noticed the strange movement under his feet and quickly hummed back the notes corresponding to the stone slab under his feet.

But to no avail.

"If this is the case, there will be an insurmountable height difference between it and the stone slab behind it."

Nina used the light to search hard, and finally saw clearly the position of the nearest stone slab while continuing to fall.

"Li Jing, follow up."

She said and jumped towards the stone slab. Although there was a slight height difference, she could still climb up smoothly with her arm movements.

Li Jing understood, looked at Nina who stretched out her hand to him not far away, and quickly followed her.

"careful!"

The boy's height and leg length caused a fundamental disadvantage to Li Jing, and the stone slabs under his feet continued to fall.

Li Jing planned the distance and jumped, but when he reached the edge of the stone slab, his body suddenly fell.

"Oops."

"Li Jing!"

Above the abyss, the young man's eyes widened in disbelief, and his body fell uncontrollably.

On the other side of the grotto, in the mirror maze.

After Wu Yu broke the mirror corner, the brightness and sound volume of the cave were reduced to varying degrees.

Fortunately, Shu Heng took the opportunity to see clearly the area behind the mirror, so that the two of them were no longer completely confused in their future exploration.

Wu Yu felt dizzy as soon as he raised his head to look in the mirror. At this time, he was grabbing Shu Heng's clothes and following him steadily.

Unable to see from all directions, Wu Yu could only stare at the material on Shu Heng's back.

At a moment, the light in the mirror maze suddenly increased, even a little dazzling.

"ah!"

Wu Yu screamed in surprise.

"Did you feel the light suddenly intensify?"

Shu Heng's eyes were also dazzled, and he instinctively raised his hands to cover his eyes.

"Um."

"Why, why did it suddenly become stronger?"

Shu Heng had some thoughts in his mind and suddenly thought of something.

"It's Li Jingnina and the others, it's because of their behavior."

"Different areas of the capsule are essentially the same."

"Don't you feel that this light is suddenly added in?"

After Wu Yu heard Shu Heng's words, he raised his head hesitantly.

"Yes, really?"

"Li Jing, Nina, is that you!"

She called out loudly to the mirror wall.

Still haven't waited for a response.

Shu Heng urged.

"Let's move on. They shouldn't hear us."

"Perhaps the correct way to clear the mirror maze is to break the mirror?"

"Yeah?"
