Before the words fell, everyone saw a black shadow falling on the top of the crocodile, knocking the crocodile into a dizzy state, sinking to the bottom of the water on its belly, and then slowly floating up, swimming away.

Yan Hui withdrew his hand expressionlessly, took Yan Zhijin's hand, wiped off the water stains on his hand, and wiped the crevices of his fingers carefully.

Yan Zhijin's already white skin was reddened by his rubbing, and the skin was almost torn.He pressed Yan Hui's hand: "Okay."

Yan Hui bent down, put his hand on top of his head, half-closed his eyes, and rubbed his palm with the top of his hair, his deliberately slow tone seemed to be suppressing some kind of impulse: "Why do you want to touch that rough and dirty place?" Things, maybe they will be infected with parasites, wouldn't it be good to touch me?"

From the corner of his eyes, Yan Zhijin saw the eyes of a group of people next to them light up like festive lanterns, and they patted him on the top of his head twice symbolically, saying: "The hard exterior is their weapon to protect themselves, isn't it? Something that should be disliked."

Yan Hui's eyes were cloudy, and his round pupils had a vague tendency to become vertical pupils.

The onlookers huddled together, their teeth chattering.

The crocodile is not so afraid to swim over.

"But the touch is not as good as snake scales." Yan Zhijin's lips moved, and he finished quickly in a voice that only two people could hear. Suddenly, he rubbed his head twice with force, then quickly withdrew his hand and moved away. He looked away, pretending he hadn't said anything.

Yan Hui slowly broke into a smile, straightened up, picked up the mineral water and handed it to him, put his shoulders against his shoulders, and said affectionately: "I think so too."

The boat moved on.

Hu Peng and others gradually adapted to the environment surrounded by crocodiles.In fact, they don't seem to have much interest in this group of monstrously large creatures.

That male caiman was no exception, and it appears that now is the time for them to reproduce.

Shen Zhiyu pointed to a pair of shameless crocodiles stacked on top of each other and yelled, "Their posture! This posture looks like a human being."

"Humans resemble them, many animals are like this," Yan Zhijin asked, "Do you think this pose is familiar?"

Shen Zhiyu: "Ah..."

Yan Zhijin frowned.

Shen Zhiyu quickly changed the subject: "Do they lay eggs? In the water, or on the shore?"

"It's oviparous," Yan Zhijin knew that he was deliberately diverting his attention, so he didn't expose it, but followed his words and introduced in an orderly manner, "They will build nests on the shore to lay eggs, and the female caiman will guard the nest Nearby, waiting for the cubs to hatch. Generally, there will be 20-40 eggs at a time. The sex of caiman cubs is dominated by the incubation temperature, and the temperature above 32 degrees is usually female, and below 32 degrees is usually male.”

Shen Zhiyu & Hu Peng and others: "???"

Yan Zhijin added: "All crocodiles are like this."

Shen Zhiyu muttered to himself: "Isn't it true that babies born in winter must be male babies, and babies born in summer must be female babies?"

Yan Zhijin said: "They have relatively concentrated breeding time"

"No, I mean, if they were human, wouldn't they be alphas in winter and omega in summer, and they can manually control their gender!"

"Yes. Caimans use this trait to balance the sex ratio of their young."

Shen Zhiyu held her chin and smirked: "Although I don't know what it's useful for, this setting is very suitable for science fiction works. Brother, did we also hatch in an environment above 32 degrees?"

Yan Zhijin asked, "What is the body temperature of a human being?"

Shen Zhiyu: "Uh... 37 degrees?"

"The artificial womb will try to restore the real gestational environment. In theory, human gender is not affected by temperature."

"Oh... I see." Shen Zhiyu curled her lips, "How interesting is the crocodile, so that it can produce alpha and omega energy, omega above 34 degrees, alpha below 30 degrees, and beta in the middle. Then everyone produces alpha. , They gave pregnant women saunas one after another, and did not turn on the air conditioner at more than 30 degrees. Pregnant women living in the north went south one after another, and the supply of hospital beds in the south was in short supply. The pregnant women had a fever every day, and their body temperature soared. The family members cried with joy, and asked him to keep going , the higher the body temperature, the stronger the alpha will be. Then the pregnant woman will have a fever and die, and before she dies, she sees that her child has become the strongest alpha, smiling at Jiuquan."

Although he was smiling, the scene he described made the people around him shudder.

Yan Zhijin said lightly, "We are warm-blooded animals, viviparous."

Shen Zhiyu was discouraged all of a sudden, and patted himself on the forehead: "I don't care, the big deal is to create a new planet full of crocodile people!"

"The crocodile is not the stronger the higher the incubation temperature."

"Settings! They're all aliens, so can't they be a little more special?"

The boat continued to move forward, just in time to see a couple of crocodiles building a nest with fallen leaves on the shore and burying their eggs in the ground.

"It's quite warm." Shen Zhiyu asked, "Do they have a sense of family?"

After finishing speaking, he laughed himself: "No, no, there should be no reptiles."

"Not really. But caimans are relatively social. Cubs hatched in the same area, no matter who the mother is, will be managed by an older female crocodile, and they move together. Their language is also very rich. , we just heard that too."

"To be honest, it's not majestic at all, and it doesn't fit their image."

"In crocodiles, they're not that big."

The female crocodile was on the shore, watching them vigilantly and fiercely.

"Why do I think it's very hostile?" Shen Zhiyu asked behind Yan Zhijin's back.

"It's protecting its cubs," Yan Zhijin's eyes glowed with warmth, "They will stay near the nest until the cubs hatch. When the cubs hatch, they will hold the cubs in their mouths and wrap them in their mouths." They send them to the water, and if there are cubs who find it difficult to break their shells, they will not give up, but help them break their shells."

"It's so tender." Shen Zhiyu sighed.

Hu Peng's camera also set up a camera, ready to shoot this warm scene.

Suddenly, a figure with black spots on a yellow background popped up from the corner of the screen, biting the neck of the female crocodile and dragging it away.

The whole action happened so quickly, the cameraman forgot to even move the camera.

The vigorous figure is dragging the huge prey forward in the jungle.

The caiman opened its mouth wide and struggled with its short forelimbs stretched out, but its weak point was caught by the leopard, no matter how hard it struggled, it was useless, and it didn't take long to move.

They seemed to be able to hear the sound of skulls shattering.

"Is it a leopard?" Shen Zhiyu swallowed, and said in a difficult voice.

Yan Zhijin sighed softly: "Yes. They like to prey on caimans very much."

Yan Hui raised his hand and asked, "Do you want to save it?"

Yan Zhijin shook his head, his tone was still somewhat sad, but also extremely firm: "No. This is their survival rule."

He said: "It is because of their weak fighting ability that caimans have evolved this highly socialized activity mode, and use the number of reproduction to make up for the population loss caused by being hunted and killed the day after tomorrow. This is the whole region, in the long history. , a naturally formed stable and balanced biological law."

Shen Zhiyu touched his chest and said, "But it's still very sad. Its baby hasn't been born yet. Can a baby crocodile without a mother be born safely?"

Yan Zhijin: "Its child may also enter the belly of the leopard in the future."

Shen Zhiyu: "...It's even more terrifying!"

Hunting this activity also greatly consumes the physical strength of leopards.With its dying prey in its mouth, it walks gracefully into the distance.

"Where is it going?" Shen Zhiyu poked his head out and asked.

Yan Zhijin gestured for silence, and whispered, "It's not far ahead, let's follow it."

The others seemed to be shocked by the scene of the leopard hunting the caiman, and fell into a dull silence.

The boat moved forward in silence.

The leopard walked to an open space, put down its prey, and called out. Several furry cubs ran out and circled around it.

"Little Leopard!" Shen Zhiyu's eyes lit up.

The leopard confirmed the safety of each cub and began to teach them to bite food.

The little leopards clumsily tore at their prey, but instead of biting the crocodile meat, they threw themselves on all fours, their big round eyes being particularly ignorant.

The leopard mother is always vigilant, observing the movement around her.

Leopards are fierce, but they are superior in appearance.So even though it brutally killed a one-meter-long caiman just now, Hu Peng and others were still not as afraid of it as they were of crocodiles.

"This smooth figure, this vigorous posture, and these deep eyes," Hu Peng said intoxicatedly, "is really a beautiful big cat."

Shen Zhiyu struggled and said: "The little crocodile is so pitiful without its mother, but the little leopard is also so cute, it would be so pitiful if it doesn't have enough to eat."

"Yes, so we can't interfere," Yan Zhijin paused, and said, "Even if he's not cute, that's the same."

He said: "Even if the caimans are preying on leopard cubs, I will not interfere. Whether it is appearance or survival ability, they are equal in my heart."

Except for people, whose power has exceeded the existing balance system.Man's attack on other living things may really cause a fatal blow to them.He can accept that cats hunt birds for food, but he cannot accept that humans hunt kingfishers for their bright feathers.

Shen Zhiyu rested her cheeks on her hands, smiled so much that her eyes turned into crescents, and asked Yan Zhijin, "Brother, have you seen so many wild animals being killed, have you really not felt compassion?"

Yan Zhijin said frankly, "I moved, but I didn't interfere."

"Just think about it in your heart, right?" Shen Zhiyu thought for a while, with a wicked smile in his eyes, and asked, "Is there really no accident at all?"

"No."

"What if it's a snake? If it's a snake, can you bear it?" He asked teasingly.

"also not……"

Halfway through Yan Zhijin's answer, he suddenly froze and looked at Yan Hui unconsciously.

Yan Hui was also looking at him, his dark pupils were like black scales gleaming in the moonlight.

His throat rolled, his throat seemed to have been burned by fire, and it was hurting: "..."

Have.

The first and only time he made an exception was to bring the injured black snake back to his home planet from the distant M planet, and hide it in a locked room in the laboratory.
