This is an ape-man child, and his height is already about the same as Zhao Xinghua, but its age can still be deduced from its clear eyes.

"What's going on!?"

Xie Yunhao asked with a look of surprise.

What's going on with this Zhao Xinghua? As soon as he turned around and came back, he brought back an ape-man hand in hand.

"This should be a lost little ape-man, estimated to be three or four years old."

"It's almost taller than you, how can it still be a child! You don't want to send it home, do you? ”

"I can't bear to do it."

Xie Yunhao looked at this fluffy young ape-man, and he couldn't bear to make up his mind to kill the killer in his heart, especially the big clear and bright eyes, which gave people a sense of innocence.

"Forget it, it's better to protect rare species, tigers and leopards eat people, but they are still not protected animals? This population is even rarer, a veritable living fossil. We can't really completely exterminate these prehistoric humans, and since they can reproduce to this day, we shouldn't cut off the incense here in your and my generation.

"But now we're not going to take it, are we?"

"That's all it can do for now."

"Major Zhao, do you have some love overflowing? Want to adopt a small animal when you see it? ”

......

Starting from the location of the big stone henge just now, two Homo sapiens and a small ape-man walked along the river for more than an hour, and the young ape-man did not have a view of right and wrong and race, it may be afraid that a "person" would stay in this dim and damp world, and he honestly followed the two enemy humans behind him.

When a few people passed by a tall brown fern, the young ape-man suddenly let out a rapid roar, Zhao Xinghua looked at it, and saw that the wrinkled face of the little ape-man showed an anxious and frightened look, and understood that it must have sensed the danger, so he stopped at the moment and pulled out the war knife, Xie Yunhao also looked around, looking for the origin of the crisis.

A huge white worm came out of the ground, and the reason why it was called huge was because the group was 6 or 7 meters long, and its fat body weighed hundreds of pounds.

The worm was covered in slimy slime, had two fist-sized tentacles on the top of its head, was grayish-white from top to bottom, had no feet, and looked like the slugs common in the southern summer, only magnified countless times. It is a yin-loving, tide-loving creature that exudes a foul smell of decay, like a garbage can that has not been cleaned overnight in summer, which makes people feel very uncomfortable.

This white giant triangular slug belongs to ancient creatures, 180 million years ago in the Gondwana continent period has survived, they feed on plant branches and leaves when they are young, when they grow to a certain volume, the nutrients in the plants are no longer enough to maintain the energy they need, they eat rotting animals and plants for a living, as long as the nutrition is enough, they can keep growing crazy.

Although they appear to have no scales or clawed feet, the mucus they secrete can hold their prey, use their massive flesh to envelop them, puncture their prey's body with their sharp, spiny mouthparts, and suck the blood from the wound vigorously. The giant triangular slug, usually hidden under the dead branches and leaves, has a layer of camouflage attached to its body, which is difficult to spot, and if you are not careful, it can easily become its prey.

However, when Zhao Xinghua and the others saw this prehistoric triangular slug, it was in a state of splitting. By the time the creature grows to a certain extent, it is difficult to absorb enough nutrients to sustain its massive body. So this primitive slug will choose to divide itself, splitting into two smaller larvae, this process is very long, often takes half a month, and this stage is also its most vulnerable period.

Zhao Xinghua and Xie Yunhao didn't realize that this was a prehistoric triangular slug in the split stage, and the two stopped more than ten meters away from it. In the face of such a big guy and a fat body, the war knives in the hands of the two are useless at all.

The little ape-man behind him let out a rapid hiss again, and there was already a tremor in his voice, Zhao Xinghua looked back at it, and found that the little ape-man's body couldn't help but tremble, and his eyes looked at their right rear blankly. Zhao Xinghua secretly said carelessly, his attention was attracted by this big insect, and he hurriedly turned around and looked in that direction.

Even he couldn't help but shudder at this moment, it was a large lizard, although its body was not as huge as this prehistoric triangular slug, it was also several meters long. If Tang Haoyu was here, he would definitely exclaim, "This is an ancient monitor lizard!" ”

(The Australasian monitor lizard, also known as the megalodon, is an extinct giant monitor lizard that disappeared from the surface of the earth about 40,000 years ago.) British biologist Stephen Rowe theorized from the skeletal structure of the monitor lizard that the monitor lizard was a ferocious carnivore capable of attacking prey twice its size and 10 times its weight, and its main tools were jagged teeth and huge claws. ）

"What to do?!"

Facing the prehistoric triangular slug, the two only need to turn around and escape, without legs, the triangular slug that only relies on its body to squirm and travel cannot chase the two, but if it is replaced by this car-sized lizard, the two don't know if they can run away.

Xie Yunhao lifted the Type 95 assault rifle behind his back.

"Don't shoot yet, that lizard doesn't seem to be coming at us."

The prehistoric triangular slug also sensed danger, and if it was usual, it was not afraid of these lizards with its fat body, and if it was one-on-one, it was capable of enveloping this prey, which was less than a third of its weight. But now, a few days ago, the body had begun to enter a state of division, all the energy was used to maintain the ongoing replication and separation of various organs, and the various functions of the body were not in the usual state, and it was impossible to control the vigorous and complex movements.

Sure enough, the monitor lizard's eyes did not look at Zhao and Xie, but excitedly stared at the prehistoric triangular slug, which was almost unable to resist. It was a big puddle of fat......

There was no danger of leaving the place where the lizard was eating, and walked out of more than ten miles, all kinds of strange insects and prehistoric creatures along the way to see a lot, thanks to this little ape-man with him, every time he would call the police in advance before encountering danger, and now when Xie Yunhao looked at it again, there was a smile in his eyes.

It's just that after walking out for most of the day, they still haven't seen any human tribes, and they haven't even encountered underground apes, which makes the two very confused. Is it all delusion? There are no sapient beings here at all? But when he saw the little ape-man who had been following him, he immediately dispelled this idea.

"Do we want to think differently, maybe because there are many large insects and beasts near rivers and water sources, so humans will choose to live in an environment with less harassment?"

The two of them were thinking about no longer traveling along the river, but exploring inland, when a continuous "bang~bang~" crashing sound suddenly sounded in the distance.

Zhao Xinghua's face was happy, this kind of high-frequency collision should have been caused by weapons, and there were people fighting nearby. Now, whether it is the Australopithecus or the Western Han Dynasty, as long as someone appears, it is better than them looking for it blindly.

The two of them immediately leaned in the direction from which the voice came, and the little ape-man followed them lightly.

Through the gaps in the branches and leaves, Zhao Xinghua and Xie Yunhao saw more than a dozen burly apes attacking a group of humans, and those humans numbered as many as hundreds, erecting spears more than one zhang long on the outermost periphery to resist the ape-men approaching, and there were people inside who kept firing crossbow arrows outward. Where the bolts hit, bursts of blue fire erupted, making the ape-men very suspicious. The first few apes had already burned large holes in the wooden armor that had been shot, and the fur inside also emitted a scorching smell.

"What kind of weapon is this? Can it even play the function of attachment and combustion? ”

Although the arrows were not fired in a dense and frequent manner, the apes did not dare to continue to approach them. Both sides seem to be testing each other's restraints, not as if an all-out conflict is about to erupt.

"Shall we go over and help now?"

"Wait and see, if you go out rashly now, you won't be attacked by both sides. When the scuffle starts, we will directly kill the enemy and take a stand. ”

"There are some apes over there, oh? There are so many humans! ”

On this narrow plain, several groups of apes and humans came in groups from two directions. The human side was divided into three phalanxes, the number of people varied, the largest group had more than 200 people, and the other group was relatively small, only a few dozen people, they looked more sturdy, and the weapons in their hands were crystal crystal battle axes.

"This can also be used as a weapon!"

Zhao Xinghua and Xie Yunhao exclaimed in a low voice almost at the same time.

The crystal axes were shaped like shells, tied to wooden handles of different lengths with rattan, and looked like a gorgeous and crystalline craft, without a hint of slaughter.

In ancient China, crystal was known as more than ten kinds of names such as water spirit, water blue, water jade, and spar. According to the standard of modern people, rock crystal is a quartz crystal mineral, and its main chemical component is silica. When silica crystallizes perfectly, it is crystal; The crystallization is imperfect is quartz: after silica gelatinization and dehydration, it is agate; The aqueous colloidal of silica becomes opal when it solidifies; When the silica grains are less than a few microns, they form chalcedony, flint, etc.

The hardness of pure natural crystal is very high, ranked by Mohs hardness, the highest hardness in the world is 10Hm for diamonds, and 7Hm for crystals, which is equivalent to the hard strength of steel files. The hardness of our commonly used steel blades is 5.5Hm, and the hardness of brass is only 3Hm.

Moreover, natural pure crystal is piezoelectric, that is, when subjected to directional pressure or tension, the crystal can be made perpendicular to the surface of both sides of the stress with the same amount of opposite charges. Therefore, if the monomer crystal is cut into a certain geometry in a special way, and then a pair of appropriate electrodes are added to the surface, its mechanical resonance performance is coupled with the piezoelectric effect to become a piezoelectric resonator. This is also the reason why in Western film and television novels, magicians will choose crystals to make magic wands and inlaid energy bodies of magic weapons.

Before the end of the world, people used the piezoelectric properties of crystals to be widely used in the manufacture of resonators and filters, and were used in navigation, remote control, telemetry, electronic telecommunications equipment and other scientific and technological technologies such as automatic weapons, electron microscopes, chronographs, electronic computers, and artificial earth satellites. There is a core component in the electronic watch called the quartz oscillator (small resonator), which is a key part that ensures that the quartz watch has a higher accuracy than other mechanical watches.

And in this team of sixty or seventy people, there are men and women, all uniformly dressed in wooden armor, although the size of the crystal battle axe is different, but its team marches and moves in a uniform manner, and each of them exudes a brave and fearless momentum, it can be seen that they are the main battle team of these human beings.

On the side of the underground ape-men, more than 200 people have been assembled one after another, and most of their weapons are stone axes, stone hammers, and some spears. They stood scattered across from the human position, and an older female ape-man stood in the middle of them, draped in a few

A cloak made of colorful thatch, with a necklace made of small animal skulls hanging from its chest. The other apes let out strange cries of all kinds, looking eager to try, waiting for the older leader to give the order to attack.
