Behind the waterfall.

The sound of water in my ears continued, and it rained like a heavy rain.

Suspended in mid-air, Lin Feng's eyes were like lightning, and in an instant, his right fist roared out, like lightning and thunder.

Disheveled~!

The huge stone wall brought a huge trembling sound, turning into countless broken stones and falling down, with Lin Feng's current physical strength, no matter how ordinary a punch was, it was extremely powerful. However... There is only one more 'hole' in this huge mountain and stone wall.

"Oh?" Lin Feng's eyes flashed.

"It's a hard stone wall. Lin Feng was very clear about his liliang.

Despite the strength, the punch just now was enough to 'open' a ten-meter-deep cave.

But right now, only a 'hole' has been made.

Bang~~Bang~~

The gravel falls, accompanied by the sound of the rushing water of the waterfall, as if playing a piece of music, which is pleasing to the ear.

"Huh?" Lin Feng's expression changed slightly, he leaned over and looked down, his eyes looked a little puzzled, "The sound of falling stones seems to be a little abnormal? What is that......"

"Echo?" Lin Feng said in surprise, "Could it be that there is a natural cave under the waterfall?!"

A thought suddenly popped up in his heart, and Lin Feng suddenly galloped down.

"Whew!"

It's like a sharp arrow.

The afterimage flashed, and Lin Feng arrived in a blink of an eye.

"There really are natural caves. Lin Feng's eyes were bright, and a faint smile crossed the corner of his mouth.

The cave is not big, but it is not small, and it has a damp feeling. Lin Feng's complexion kept changing, and he was extremely frightened.

"In the hole. There are two streams of energy faintly seeping out?" Lin Feng said.

Moreover, one of the energies is quite familiar to itself!

White Mist!

Stepping in, Lin Feng was curious, and a faint aura of energy filled the air, getting deeper and deeper the deeper he went. Instead of mud and rock, there was a strange crystal of water that reflected the cave with a pale green glow. It complements the white stalactites to form a delicate pattern.

"It's beautiful. Lin Feng admired softly.

Although the entrance to the cave is not large, it is extremely spacious to enter.

The soothing breath carries a hint of hazy mist. It's like a paradise, in stark contrast to the thick black fog outside.

"It saved me a lot of effort. Lin Feng smiled, and his heart and eyes spread out. His eyes lit up, "Sure enough, there are different energy breaths on the left and right sides!"

The cave is large, with more bifurcations, and extends in all directions.

Under the division of the strangely shaped stalactites, a labyrinth-like existence is formed.

But......

For Lin Feng, who can use the mind-eye sense, this stalactite cave is like stripping naked, and there are no secrets.

"Let's go to the left first. Lin Feng nodded.

The breath on the left side is warm and makes me feel more intimate.

Step by step, in the direction of the sense. Lin Feng looked curiously at these strange-shaped stalactites along the road, bamboo shoots, columns, curtains, grapes, flowing clouds, waves, all kinds, all kinds of them, as if they were statues.

My heart moved. Lin Feng touched it gently.

"Oh my God!" In an instant, Lin Feng's complexion changed greatly.

"These stalactites...... It turned out to be a Tianbao spar?" The tentacles were cool, with a familiar sense of heaven and earth energy.

Wrong!

"It's not a Trimble Crystal. Lin Feng shook his head.

And then carefully probe these 'stalactites', which are fundamentally different from Tianbao spars.

Tianbao spars are formed by the convergence of pure heaven and earth energy, but these stalactites are formed by the condensation of two energies. In addition to the breath of heaven and earth energy. There is also a strong sense of vitality, full of a sense of life, as if full of green grass.

The corners of his mouth grinned slightly, and Lin Feng smiled.

Although it is true that these stalactites are inferior to Trimble spars in terms of 'purity', .........,
