Glancing at the entrance of the cave sealed by thick soil, Ye Xianglun patted the shoulders of the two of them, and the three of them walked towards the dark cave at the same time.

Since there was no light entering the cave, and it was night, he couldn't see the environment in the cave with his eyes alone, Ye Xianglun took the two of them by hand with his keen perception and walked slowly.

"Why are there so many water trails on the ground?" asked Miss Mu, who was holding her hand on the ground, after getting up.

"It should be the water of the mountain spring infiltrated by the rock wall!" Ye Chen replied calmly under the support of Ye Xianglun.

Sure enough, the further they went, the more humid the air in the cave became, and the footsteps of the three of them had become muddy at this time.

"Click-"

A drop of water slipped down from the rock wall at the top of the cave, and happened to drop on Miss Mu's cheek, and in the completely dark environment, Miss Mu, who was suddenly frightened, subconsciously leaned on Ye Xianglun's shoulder.

"Why did I forget this!" After realizing Miss Mu's frightened appearance, Ye Xianglun suddenly said, "Miss Mu, you come here to hold Ye Chen." ”

"Doodoo-"

A pleasant harmonica sound suddenly sounded in the dark cave, and under the call of the harmonica sound, a golden note, shining with bright light, illuminated the environment of the cave like a bright lamp.

"Ahh

The sudden brightness made Miss Mu scream unconsciously when she saw the environment in the cave.

It turns out that this cave is a karst cave, and countless huge stone stalactites hang down from top to bottom in the cave, which looks extremely eerie and terrifying under the faint light.

"Miss Mu, don't be afraid, these upside-down 'stone forests' are corroded by mountain springs, but they just look terrifying. Ye Xianglun saw that Ye Chen beside him was also surprised to look at these upside-down stone stalactites, presumably even Ye Chen had never seen such a scene, so he couldn't help but explain.

"Doodoo-"

Seeing that the two of them were still nervous, Ye Xianglun called up a few more notes from his mind, surrounded by several notes, the brightness in the cave increased a lot, and the shadows and gloom generated by the illumination of a single note at first instantly disappeared a lot.

"These upside-down 'stone forests' look like the mountains have been torn apart, and they look very terrifying!" Miss Mu still avoided these stone stalactites in fear.

The three of them walked through a long narrow path through the stalactite forest, and the road ahead gradually widened, and the ground began to become potholed when they stepped into the wide field.

The three of them carefully walked to the center of the wide field, only to find that this wide space was an almost cylindrical space, the four walls of the cylindrical space were a circle of stone stalactites hanging down to the ground, and in the middle of the cylindrical shape, a huge stone stalactite shaped like an hourglass hung down, and the stone stalactites were closely connected to the ground, like a stone pillar supporting this circular space.

"Mr. Ye, look, there's a waterfall in front of you!" Ye Xianglun was looking up at the top of the cylindrical space, densely packed with stone stalactites, when he heard Miss Mu exclaim.

"Sure enough, it's a waterfall, why doesn't this waterfall have the sound of flowing water?" Seeing this, Ye Chen also asked curiously.

Ye Xianglun lowered his head and looked in the direction pointed by Miss Mu and the others, only to see that there was indeed a waterfall in front of the cylindrical space.

"How can there be a waterfall in this place?" With great curiosity, Ye Xianglun took the lead in the direction of the waterfall.

"From afar, the mountains are colorful, and the water is silent. Hahaha, it turned out to be a stone curtain inlaid here!" After walking in, Ye Xianglun found that this was not a waterfall, but a stone curtain, like a picture scroll, firmly inlaid on the stone wall, but the shape of this stone curtain is really like a real waterfall.

"Looking at the mountains from afar, and listening to the sound of the water up close? Mr. Ye's mouth is really admirable, this scene is really like a waterfall, but there is no sound of water. Miss Mu was obviously still silent in Ye Xianglun's poems, and she was full of praise and intoxication.

"What is this stone curtain, how does it look like a hollow stone!" Ye Chen gently tapped the hanging stone curtain, and the stone curtain made a hollow soft sound, so he asked curiously.

"The mantle, like these stalactites, is made of rock erosion, but it is different in form. Ye Xianglun explained leisurely.

"I didn't expect there to be such a wonderful scene in the cave. Miss Mu still tasted Ye Xianglun's poems and let out a faint sigh.

"Do you want to see a more beautiful scenery?" Ye Xianglun suddenly remembered the scene in the cave on the earth, and suddenly became interested.

"How can it be more beautiful?" asked Miss Mu with a twinkle of bright eyes and curiosity.

"You two close your eyes first!"

After Ye Xianglun saw the two of them close their eyes as they said, he gently played the harmonica, which made a pleasant sound, making a long echo on the stone stalactites in the cylindrical space.

"Open your eyes now and try it!"

"Wow, that's beautiful!"

Hearing Ye Xianglun's gesture, the two opened their eyes at the same time.

"These stone pillars can also emit light on their own, how did Mr. Ye do it?"

It turned out that Ye Xianglun imitated the lighting effect of the cave scenic spots, and used all the note energy in his mind to light the hanging stone stalactites from top to bottom, so that in the dark environment, the stone stalactites that were illuminated seemed to emit their own radiant brilliance. The only drawback is that Ye Xianglun only has a golden light, but even so, for the two who have never seen such a scene, the scene in front of them is also quite shocking.

"Carving insect little skill ear!" Seeing the performance of the two, Ye Xianglun withdrew the energy of the notes scattered everywhere and smiled with satisfaction.

"Rumble—"

"Rumble—"

After the energy of the notes was withdrawn, the uneven ground shook back and forth in the cave as if an earthquake had occurred, and at the same time, there was a breathtaking rumbling sound in the cave.

"Mr. Ye, look, this big pillar in the middle of the space seems to be collapsing!" Ye Chen's eyes were sharp, and he first saw stalactite chips falling above the stone pillar, and with the fall of the stone chips, the entire stalactite pillar collapsed, and in a panic, the three of them fell to the ground with their heads in their hands at the same time, crawling towards the narrow place.

The cave collapse expected by the three of them did not happen, on the contrary, in the cylindrical space, after the hourglass-shaped stalactites were shattered, a golden cylindrical energy pillar appeared in the center of the cylindrical space.

With the violent tremor in the space, the color of the energy light pillar became brighter and brighter, from the initial dark gray color, until it turned into a brilliant blue color, the trembling momentum in the cave finally stopped, and seeing that the cave was calm again, the three of them trembled and got up.

"Frightened! This place has really become a water world!" the three of them were shocked at the same time when they saw the scene in the vast space again.

"Whoa—"

"Whoa—"

Not only did all the stalactites in the space turn into flowing water columns, but even the "waterfall" composed of the stone curtain emitted a huge sound of flowing water.

"Even the ground is covered with a pool of stagnant water!" Miss Mu suddenly exclaimed after noticing the scene under her feet.

"It's not real water, it's just an illusion!"

Raising his foot and touching it, there were ripples under his feet, but Ye Xianglun found that although the ripples under his feet were painted with sound and color, the texture was still a potholed stone surface.

"That'...... Isn't this waterfall the same?" Ye Chen couldn't believe it, and touched the gushing water column formed by the stalactites before beside him, and found that the texture was the same as the stone curtain, similar to the touch of a hollow stone body.

"Come over and take a look!" Ye Xianglun was also shocked, and pulled the two of them towards the waterfall formed by the stone curtain.

The three of them walked to the "waterfall" at the same time, and Miss Mu touched her hand lightly, and sure enough, it was blocked by the texture of the stone curtain, but the visible sound of blue water pouring and the sound of water flowing around their ears still made them still unable to believe such a real illusion in front of them.

"Ye Chen, can you see the ruler spectrum recorded on the energy light pillar in the middle of the space?" After being shocked, Ye Xianglun turned around and saw several ruler spectrum symbols looming in the dark blue energy light pillar, and asked Ye Chendao beside him uncertainly.

"Music score?" After hearing Ye Xianglun's words, Ye Chen looked at it carefully, and found that in the middle of the vast space, except for the fluorescent turquoise energy light pillar, there was no trace of the ruler score at all, "Ye Chen didn't see any music score!"

"Miss Mu, what about you?" Ye Xianglun continued to ask without giving up.

"Qing'er didn't see anything!" replied Miss Mu.

"Could it be that this is the legendary Qin Array?" Ye Chen suddenly shouted in horror.

"Qin array?" Ye Xianglun and Miss Mu were surprised at the same time.
