I dig ancient tombs for the country

A hexagonal flaky crystal object, transparent and smooth, with a halo in the dark hole, looks like glass but not glass, because it seems to be mixed with several colors of red, yellow, blue, green and white , Under the reflection of the torch, there is a kind of colorful glazed light.

Could this be the mica mentioned in the book?Mica is a kind of rock-forming mineral, which is in the form of flaky crystals with various colors, including white single crystals and multi-layered crystals mixed with red, yellow and green.The main characteristics are insulation and high temperature resistance, and it is an indispensable substance in industry.

"Brother Tao, is this mica?" Hongmao looked at me suspiciously, his big eyes were full of light of surprise.

"It's possible. I heard that this thing is very valuable. Could it be that Uncle Su's secret is referring to this?"

"Perhaps, is there a layer of mica inside this wall?" Hongmao pointed to the cave wall and searched carefully.

I kept tapping every place on the wall with the hilt of my sword, hoping to find the entrance to the inside.I searched back and forth many times, but found nothing except the small flaky crystal?

"Brother Tao, could it be that we guessed wrong, there is no mica here at all?"

"Then how do you explain this piece of mica? What is the secret that Uncle Su said?" I asked Hongmao back.

Hongmao spread his hands helplessly, "Ask me, I'll ask who to go to. Strange, if this is the secret that Dad discovered back then, there should be a secret passage or entrance, but there are still big rocks besides the big rocks on the wall. How do we get past the wall?"

I shook my head and said with a wry smile: "If those little Japanese found the mica layer, they would never give up easily. There must be a way to enter, but we didn't find it."

"Then look for it again?" Hongmao said and bent down to search again.

I leaned on the rock wall and thought about what happened in the past two days carefully. I just felt that something went wrong, but I didn't find any clues now. What could be the problem?I couldn't figure it out, and kicked a stone on the ground angrily, and a wonderful thing happened like this.

Following a strange sound, a square hole appeared above the heads of the two of us standing, and the hole opened obliquely to the outside of the wall.

"Haha," it's really hard to plant flowers and flowers if you want to, but you can't plant willows and willows to make shade.

"That's great, Brother Tao." Hongmao jumped up in surprise, raised his fist and gave me a slap, and I grinned in pain: "How can you praise someone like this? Are you going to go first or should I go first?"

"Let's go up first. I'll check the situation first. What if there's any danger? It's better for you to respond below."

"Well, be careful." I squatted down and let the red hair step on my shoulders, and then I stood up slowly. He grabbed the rock at the entrance of the cave with both hands, lifted his body up, and entered the entrance of the cave.

"Wow, it's so beautiful! Brother Tao, there really is a cave here, come up and have a look." Hongmao lay on the edge of the cave, and threw down a rope. I grabbed the rope and climbed up the cave, waiting for me to jump down , was immediately stunned by the sight in front of him.

This is obviously another cave, the surrounding walls are covered with strange crystal-shaped stones, some are big, some are small, and there are all kinds of shapes. Those stones are shining brightly, and the whole cave is full of rays of light. , the beauty is like a colorful world.

This is unbelievable. We touched the mica stones on the wall, our eyes sparkled excitedly. There are so many treasures in this mountain. If we didn’t happen to discover them today, wouldn’t these mica stones still exist? Buried in this deep mountain, it will never see the light of day.

His grandma's, these nasty little Japanese, found such a good thing and didn't report it, but secretly set up a secret base here and excavated it by themselves.It appears that the Japanese had not had time to remove the mica in their hasty evacuation of China.

"Brother Tao, take a look at this piece, it's a bit special." Hongmao shouted at me.

When I walked to Hongmao, I saw him pointing to a columnar crystal for me to see. It was a cone-shaped columnar double-sided crystal with horizontal stripes on the crystal surface, which looked like the ripples of the sea at first glance. , looking carefully, each horizontal stripe is like a piece of scale, evenly distributed on the crystal, with slight light yellow, light green, light gray, light white and other colors inside, the surface presents a glass-like luster, and the inside reveals Round and lustrous like a pearl, this tapered cylinder shone with a different kind of brilliance in this bizarre hole.

Nature is really strange, creating all kinds of different creatures, just like these crystals, they grow silently on this rock wall, waiting to be mined and excavated, waiting for their own value to be recognized by the world.

Going further in, the cave wall is full of gouging scars, full of uneven pits of different sizes. The mica stones in these places must have been dug away by Little Japan. The eye-catching scars on the rocks, some as wide as , some are narrow, some are round, some are square, and there are still many crystalline rock masses around the scar.

The scale of this cave is very large, tens of meters if not hundreds of meters. Under the dim light, it looks like a maze, and it actually divides into two different roads while walking.

One leads straight to the depths of the cave, and the other diverges to the left.

Standing at the fork in the road, the two of us didn't know which way to go.The red hair said to take the path on the left, and I said to take the path in the middle. Just when we were undecided, there was a faint sound of iron chains clinking and an ax hitting the wall from nowhere.

The two of us hurriedly held our breath, restrained our minds, and quietly searched for the source of the sound.There are still people here?And it seems that they are still digging the mica stone on the wall. Besides that deaf and dumb Luo Shihai, is there anyone else in this hole?

But when you listen carefully, there is no sound, which is really strange.Finally, Hongmao and I decided to go to the hole on the left to see if there is also a mica stone in that hole.

As soon as he took a step, there was another sound of metal knocking in his ears, and this time the sound of knocking lasted for a long time, and then he couldn't hear it again.

It's really evil. With my unique inhuman hearing ability, I can't hear the source of the sound. The sound seems to come from all directions of the cave wall. It is intermittent and intermittent, giving people a mysterious feeling.

The mica stones on the surrounding rock walls glow indistinctly in the dark cave from time to time, reflecting the strange expressions of Hongmao and me. My hearing and sensitive sense of smell have completely lost their function in this cave.

It's like a strange echo wall here, which makes you puzzled and unable to hear the source of the sound.
