You must know that when the earth was first formed, it was a hot magma ball, and the atmosphere was full of carbon dioxide, ammonia, methane, hydrogen sulfide and other gases harmful to life, and there was almost no oxygen in the atmosphere, let alone signs of life.

Later, under the action of wind, rain, thunder and lightning, organic matter was formed, and by chance single-celled life was formed, which changed the composition of the oceans and atmosphere very slowly.

It wasn't until the increase in the oxygen content of the sea and atmosphere that life finally exploded in the Cambrian period, 540 million years ago, and the earth became colorful.

After Chen Rui walked alone in the rainforest for half a month, he had an extra companion by Chen Rui's side, an adult male jaguar named Black Spot.

Black spots are the name Chen Rui gave to the jaguar because of the black spots all over its body.

Maybe it's because of the aura in the space, maybe it's because the jaguar ingests enough nutrients every day, maybe it's because the jaguar's physique is different from that of humans, and its injuries recover quickly.

After more than half a month of recovery, a long, deep wound on the front right leg had been completely healed a week ago, and now only a finger-thick scar can be seen on the outside of its front right leg.

The calf bone of the hind thigh was broken, and it recovered quickly, and the splint had already been removed, and although it could not do vigorous running, it was already possible to trot on the ground.

I believe that it will be completely cured in another half a month.

With the addition of Black Spots, there is a lot of fun to travel through the rainforest.

The black spot kept trotting around Chen Rui's thigh, and his waist kept rubbing against Chen Rui's thigh.

Sometimes they will run and rush into a bush, startling countless birds and small animals, and making chickens and dogs jump.

Sometimes he would suddenly run out of Chen Rui's sight, and after a while, he would come back with a prey in his mouth, put it at Chen Rui's feet, rub Chen Rui's thigh with his body, put his front paws on Chen Rui's body, and then use 7 or 8-year-old children to take the initiative to do something for their parents, hoping to get praise from their parents to look at Chen Rui and take credit.

Chen Rui usually strokes the neck hair of the black spot with his hand at this time, then pinched its ears, rolled up its ears, and then let go, rolled up again, and let go again, which is the favorite way of frolicking for black spots.

Every time this happens, it squints its eyes lazily and enjoys it.

On this day, Chen Rui walked in a jungle.

Suddenly, a strange sound came from not far away, like the leaves being blown by the wind, followed by the screams of animals, the sound of struggle.

Immediately after that, countless animals rushed past Chen Rui and fled in panic.

It seems as if some great catastrophe is coming.

A few minutes later, in a swaying pine forest, an astonishing scene unfolded in front of Chen Rui's eyes: thousands of ants, each ant was larger than ordinary ants, looking like centipedes on the outside, looking very fierce, like a well-trained soldier, they lined up in a dense and regular horizontal formation more than 20 meters wide, marching in formation, surging towards the raging tide, nothing could stop them.

Chen Rui saw with his own eyes how they passed after they touched the ravine.

The ants in front rushed down without hesitation, as if building a house and laying a solid foundation, until the ravines were filled in and the army could pass through.

Of course, this kind of scene is very tragic, because it is similar to suicide, many ants have been washed away or left behind, but Chen but no ant will back down.

This is an army of ants composed of millions, tens of millions, of very fierce and cruel, well-trained ants who are not afraid of death.

These excellent warriors are stubborn and stubborn, their bodies are as hard as iron armor, and their jaws are as sharp as scimitars, and they take the offensive with the tactics of the sea of ants, and the number of them is beyond imagination, relying on the overwhelming slashing and cutting, making the opponent tremble and flee in panic. Even the alligators, green anacondas, and jaguars of this rainforest are beasts that stand at the top of the food chain.

The prey was immediately submerged where the 'tide' of the ant army overflowed, and after the 'tide' passed, the ground left a pile of white bones and blood that had seeped into the soil.

"It's a marching ant." Chen Rui has seen it on the data.

They are the true predators of the Amazon rainforest, real super-predators.

The hunting ability of marching ants is amazing, from crickets and grasshoppers to a cow, alligators, jaguars, and any animal in the green anaconda rainforest.

Although a green anaconda is large and powerful, it has no power to parry when thousands of marching ants continue to climb its body and bite it.

The reason why marching ants are so powerful is because of their large number, and the number of an ant army can reach 1~2 million, or even more.

Second, because their saliva is poisonous, they can easily numb and paralyze their prey, and they begin to swallow their prey without waiting for their prey to die.

Marching ants are arguably one of the most feared species on Earth, with more than 400 people dying every year from their feeding.

In film and television works, the attack of ants, the siege of castles, etc., are not entirely fictional.

The 'surging black tide' came rushing in.

The dark spot was agitated, and a low growl came out of his throat.

Chen Rui collected the black spot into the space of the pregnant sea pearl, and then, he performed an earth escape technique and sank into the ground.

A few minutes later, the 'black tide' rushed to the ground above Chen Rui's head, and Chen Rui's ears heard the sound of 'swishing' like silkworms eating mulberry leaves and the sound of the wind blowing the woods, dull, but giving people a sense of palpitations.

Like the scythe of death, it swung through.

Ten minutes later, Chen Rui felt that the ant army on the ground had left.

Chen Rui drilled out of the ground.

It was quiet, a little oppressive.

On the ground around them, there were piles of dry bones and blood seeping into the soil.

A tragic massacre and massacre had just taken place here, turning this place into a place of death.

Of course, there are animals that survived.

Flies and birds flew away and escaped.

The stick insect took advantage of the blindness of the marching ant to stay still safely and escape.

The beetle trusts in its protective gear and waits for the ant army to pass.

After encountering the marching ant legion, Chen Rui was in awe of the Amazon rainforest.

It's hard to imagine what it's like to be a 'black tide' of more than 20 meters horizontally composed of millions or even tens of millions of marching ants surging towards you.

Although, after the 'black tide' passes, the life of the animals in this jungle will be completely destroyed, as if it will be wiped out, but soon after the marching ants leave, the jungle will become a hotbed of biodiversity, and all kinds of creatures will have a chance until the marching ants return to visit.
