Click, click, click-

The sound of the clear water was transmitted all the way along the cracks in the stone, and several rounded stone sockets the size of a basketball represented that the dripping water had been dripping here for an unknown amount of time, and it was hard to polish out this mirror-like depression.

Li Heng raised his head and looked sideways, and couldn't help but sigh slightly: "Such a hidden place......"

Outside, the dense wild bushes grew on top of each other, almost conforming to the mountain wall, with only a very inconspicuous entrance at this slanted angle.

If this old cow hadn't found another way, it would have been difficult to find anyone who hadn't razed this positive bush.

"What is this unfolding?"

Li Heng's heart suddenly became excited.

"Could it be that just like Yang Guo, I also met a carving brother, isn't it...... Brother Niu? A certain senior's peerless secret book has been buried in this cave for thousands of years, just waiting for me to come and cultivate? ”

"Or guess bolder, this old cow is not the green ox that Lao Tzu rode in Guguan when he sent a letter to the west, and this is the supreme fruit of Lao Jun's legacy in the world, just waiting for me, a destined person, to take it?"

"Or is this cow actually the reincarnation of the Great Sage of Pingtian Mighty Bull Demon King, and there are the secret treasures of the Seven Great Sages of the Ancient Demon Clan!"

The outrageous and bizarre brain hole can't be stopped as soon as it is opened, anyway, it is a blind thought, Li Heng simply let go of the brain hole, and let the dead fantasy online memory come back to life and attack himself crazily.

While thinking nonsense in his mind, he continued to follow the pace of the old cow into this crack.

A faint cold wind blows along the rock wall, and this air flow proves that the cave is not a dead end, and there is no need to worry about air quality when you go inside.

It's just that the more you go inside, the more damp and dark it becomes, and soon the visibility drops a lot, so Li Heng has to take out his mobile phone and turn on the flashlight lighting.

Then he saw the inside of the cave that was slowly descending, and some scratches could often be seen on the primitive natural rock wall, which were obviously caused by external forces, but they were extremely irregular and most likely not human.

"It looks like animals come and go here so often that they leave traces of movement on the rock wall, could it be a creature nest?"

Soon he saw some evidence,

A pair of withered white horns appeared not far ahead, almost completely decayed, and even the hard horns were powdered.

On the other side there is a relatively "fresh" skull, with some fur stuck to it that has not yet rotted.

As we continued, more and more of these animal remains grew, from the beginning of the scattered to the back can barely be displayed alone, a large number of bones have been turned into bone meal piled up, in this deep fissure cave looks strange and spectacular.

Li Heng was even surprised to find a pair of antlers somewhere!

You must know that wild deer have long been extinct in this land, although according to the county records, deer did grow near Pingshan in ancient times, and there are records of them being dedicated to the imperial court as a specialty.

But it is precisely because of this move that the already small deer herd in this mountain has completely disappeared, and it has been at least a few hundred years since the last deer disappeared.

"In other words, the antlers in this cave are at least the remains of deer that died here hundreds of years ago, and the other remains that have turned into bone meal or even rotted into mud are already animals that are too old to be counted."

Li Heng was taken aback, he had the impression that there seemed to be a place in the record that was similar to this place.

"Thousands of years...... No, even the burial ground of thousands of animals that have come to the bone......"

"This is actually a mound of beasts?!"

At this moment, the old cow, which had been walking slowly ahead, finally stopped, and at its feet was a patchwork of rocks, covered with gray bone meal and other humus that had been precipitated for many years.

The four hooves slowly bent, and the old cow knelt down and lay down in the "stone bed".

"Moo-"

It raised its old head and screamed in Li Heng's direction one last time, then lowered its head, the bull's eye slowly closed, and then it didn't move anymore, as if it was sleeping soundly there.

Li Heng walked up to it and gently stroked the tip of the old cow's nose, his breathing was no longer breathing, but his breath was unprecedentedly peaceful.

This creature, who has been working hard all his life, finally ushered in the final peace and leisure at this moment.

Li Heng sighed lightly, and finally stroked the scar on its neck.

"An old cow raised by a family, who only works in the fields or grazes in the cowshed all day long, can find such a primitive burial place that has been passed down from ancient times to the present day before his death."

"What is this natural magic...... Or is it the mystery of life?"

He had only heard of rumours of wild elephants having premonitions before they died, and that the old wild elephant would leave the herd alone before the last moment and bury itself in a secret place that it had never been to but was born to know: the so-called elephant mound.

This rumor has been circulating for a long time, and many people believe the story, but in the end it was only turned out to be a false rumor, which is nothing more than a lie made up by human poachers to force the elephant herd to relocate, and unscrupulous rumor-mongers to make up lies.

But today, he actually saw such an incredible scene here, in the depths of his hometown, what should he say?

"Sigh at the vastness of the world, how many unknown wonders are hidden in the world, when will you get a glimpse of the whole picture of this world?"

Li Heng held his mobile phone and continued to move forward, the cave was far from the end, and the touch coming from his feet was different from before.

It is no longer as hard as the pure rock before, and the ground here has been replaced by the remains of decaying creatures in the past, which has a strange fluffy feeling, but fortunately, it is basically the remains that have rotted early, and the smell has long since dissipated.

But even so, a unique ecological microenvironment has been formed.

Li Heng could see a thin layer of green clothes growing on the rock wall, which was an algae he had never seen before.

There are also layers of fungi that cover those humus layers, growing on the remains of these corrupt organisms that have accumulated over the years.

Some of the fungi looked like the mushrooms outside, while others were much more bizarre, such as the strange one he saw a fungal aggregate that looked like an arm with many fingers swaying back and forth in the air current.

There are also white flower-like fungi and staggered serrated biomes......

Li Heng's limited biological knowledge is difficult to fully explain the environmental phenomena in this deep crater, and it can only be said that the unique ecological environment here has made all this possible.

The fungi that grow on the bones of countless corpses attract many strange insects to feed here, and more than a dozen different communities of insects of all sizes live here, and they feed some small reptiles that feed on them......

It's like a complete and delicate little ecosystem!

Just when Li Heng sighed, a big centipede with hundreds of pairs of sharp feet in the corner suddenly crawled out, biting the small flower beetle that was feeding in the fungus bush and quickly killing it with a pair of poisonous chelas.

On the other side, a small soil lizard was sticking out its tongue to catch the gathered fireflies one by one, but it didn't notice that not far away, a black-striped pit viper also stared at it, and the complete snake body accumulated power like a spring, and its fangs instantly bit it.

Not only that, Li Heng also saw a flowery gecko with a short arm length entrenched on the top of the cave, waiting for the prey to come in and hunt the range; A black scorpion wields a terrifying pair of pincers and a stinger on its tail with a menacing menace; Two fat toads the size of fists and pimples squatted in the crevices in the corners of the cave, almost one with the rocks, waiting for the rabbits......

Li Heng's eyes widened in shock: "This is actually a place where 'five poisons are complete'!" ”
