"This special animal uses plant leaves as its staple food, and its feces are a kind of excellent fertilizer and hormone, which can stimulate the rapid growth of this plant and provide its demand..."

Leilin guessed, "And these plants and animals form the bottom layer of all food chains in the ecosystem..."

Only in this way can we explain why the cycle in the ecosystem can last for so long.

After all, this place is just an ecological laboratory, not a huge resource-based secret realm. Although the area is vast, it is not enough to support an ecosystem.

Now it seems that without the supply of outside experimenters, the organisms here have evolved a unique ecological system alone.

“Moo…”

At this time, a low roar of creatures came.

Lei Lin immediately hid his figure and looked at the species gradually approaching.

This is a creature similar to a plesiosaur, but there are also huge black carapaces on its back, and barbs with cold light are densely covered on it, which makes it look indestructible.

Its head looks very small relative to its body, with two short bulges behind its head and a long nose. The sound of the sound just now came from its nose, with a thick tremolo.

Bang! Bang!

This kind of creature is not light in weight, at least three tons or more, the ground will shake slightly every step you take.

It slowly walked to the plant where Lei Lin was hiding, with its small eyes looking graceful and lazy, and it stretched its neck from time to time, gnawing on the huge plant leaves.

And on the edge of the leaf that it had eaten, there were traces of bite marks that Leilin had seen before.

"Chip! Record this biological image. Compare the database!"

Lei Lin secretly ordered.

"Ding! Task is established, and scanning and imaging begins. Compare the database..." The chip faithfully executed Lei Lin's order and came up with the answer almost instantly.

"There is no image of this creature in the database. I started looking for those with the highest similarity to compare..."

The sound of chip machinery sounded.

"After the data base comparison, the creature is suspected to be a snake-necked tortoise, with a similarity of 87.9%!"

Subsequently, the chip provided specific information on snake-necked tortoises.

"Snake Neck Tortoise: Ancient creature, currently extinct, is an omnivorous animal, with a mild temper, and the amazing defense power of the carapace on its back is the raw material for many defensive witches. After adulthood, snake neck tortoise has the strength of no less than a level 2 wizard."

Lei Lin looked carefully at the image of a snake-necked tortoise given by the chip. This is an illustration in an ancient book recorded by the chip and has been kept in the database.

"Well! The difference between this creature and a snake-necked tortoise is that the carapace on its back is different in color, there are also some barbs, and the head is also a little different, so some mutation has occurred..."

Lei Lin was not surprised by this. In this ecological environment, the ancient species that did not actively evolve might have died long ago. It is normal to mutate a little, and maybe there will be secret promotions from those quicksand members.

On the contrary, it would be abnormal if the ecological signs that were consistent with those of ancient times could be maintained.

"Since that's the case, I'll call you a snake-necked tortoise!" Lei Lin made a decision. Anyway, the snake-necked tortoise outside had long been extinct and had no right to protest.

"Moo..." At this time, the snake-necked tortoise beside him never noticed Lei Lin. However, he had already finished eating and roared a few times. He was about to leave here.

Lei Lin's heart moved and followed him secretly.

"Shadow lurks!" Although it is just a first-level witchcraft. However, under the control of Leilin, especially with the promotion of the qi-transformed mental power, the effect it exerts is even higher than that of many second-level witchcraft.

Lei Lin's body fell into a shadow crack and crawled directly onto the back of the snake-necked tortoise.

The solid carapace is very stable and gives people a sense of safety. Lei Lin looked around and saw wide and thick leaves and huge trees everywhere. The vines hang down like numerous tassels. Drops of huge water rolled on the leaves and vines, emitting charming brilliance.

Many buds that are bigger than ordinary people are in full bloom, with extremely bright colors and various sweet smells coming, which are tempting and dangerous.

Lei Lin's nose twitched: "The psychedelic pollen, and this kind of fluctuation similar to spiritual hints, may be that third-class apprentices or even formal wizards come over and you will be caught if you accidentally..."

This place gives Lei Lin the feeling, just like the primitive tropical rainforest in his previous life, with extremely prosperous species and full of a primitive atmosphere.

The snake-necked tortoise obviously did not find Lei Lin on his back, but fulfilled his duties as a means of transportation well and continued to move forward with Lei Lin.

Its pace was very steady, and Lei Lin did not feel any bumps on its back. About half an hour later, the snake-necked tortoise carried Lei Lin to a lake.

Next to the lake is an open space, and upstream of the lake, a white river like a jade belt flows slowly, pouring into the lake, bringing fresh water here.

“Moo…”

Here, many snake-necked tortoises gathered together to form a huge group. Many snake-necked tortoises swam happily in the lake, diving from time to time, suddenly popping up, causing huge splashes of water, and at the same time, two columns of water were sprayed out from their noses, like fountains.

The snake-necked tortoise Leilin also seemed very excited and crawled towards the lake.

"There are about seventy-five snake-necked tortoises in this number!" A glimmer of light flashed in Lei Lin's eyes.

The snake-necked tortoise was not very famous in ancient times. Not only was it weak, but it didn't even have any strong bloodline in its body, which was completely useless to Lei Lin.

But they have one advantage, their fertility is very high!

The estrus period of normal snake-necked tortoises is very long. During the estrus period, they can lay nearly 100 turtle eggs every other month, and the survival rate of turtle eggs is relatively high. If you do not count the prey of natural enemies, at least half of them can be successfully hatched. As long as the food is abundant, they can grow into adults in three years and continue to reproduce the ethnic group.

"This is the rule of the biological world. It is difficult for powerful organisms to reproduce, and even if they are nurtured, it is difficult to feed them. However, low-level organisms are just the opposite. Their reproductive power and activity are incredibly strong..."

Lei Lin suddenly thought of the mice in his previous life. The fertility and adaptability of this creature is varied, and even if nuclear winter occurs, the animals that are most likely to survive are still them.

"I can feel that the mutated snake-necked tortoises here are more intense in their bodies. It is estimated that it will take less than a year to go from turtle eggs to adulthood..."

Lei Lin touched his chin. It was obvious that for the survival of the race, the fertility of these mutated snake-necked tortoises was strengthened, which was also their acquired choice.

From these evolutionary choices, we can see that snake-necked tortoises are definitely not a top-level existence in this ecosystem, but rather the lowest food chain, predated.

"Thirt!"

Just as Lei Lin was about to get some blood from the snake-necked tortoise back to see what could be discovered, a roar cries came from a distance.

This sound is extremely high and has extremely powerful penetration.

Many snake-necked tortoises started to rush towards the lake quickly. The likes among the lake dived deep into the bottom of the lake and never dared to show up again.

The sound of crying became louder and louder, and with Lei Lin's enhanced physical fitness several times, a trace of blood could be seen shooting from the distant sky.

It was a huge eagle creature with hard and smooth feathers on its body, blood-red, and there were several clusters of strange golden feathers on its head, forming the style of a crown.

"Blood Eagle! Ancient creatures, with sound attacks, can manipulate the blood in the target's body. They have a strong interest in various items of cherishing blood. They are ethnic creatures. Evaluation: Extremely dangerous!"

The chip immediately projected a piece of documentary materials in front of Lei Lin.

"Blood Eagle!" A hint of shock appeared on Lei Lin's face, and then he turned into joy.

"This creature has an unthinkable sensitivity to those unusual bloodlines and has high altitude vision. It can even see a hair on the ground clearly at an altitude of more than 10,000 feet. It is often held by ancient warlocks to find some strange bloodline objects!"

"Just..." Looking at the extremely dangerous evaluation of strength given by the chip at the end, Lei Lin hesitated a little again.

The bloody vulture alone exudes a powerful power that Lei Lin dared not ignore. According to the level of human beings, he has entered at least a level three.

Moreover, the chip makes it very clear that this blood vulture is a tribal creature. There must be many third-level members in its nest, and even the king of the blood vulture! As the leader of the entire tribe, the blood vulture king is definitely a third-level crystallization existence. Even if he reaches the level 4 Morning Star realm, it is very possible!

"Chir!" The blood eagle circled in the sky, making the snake-necked tortoise on the ground panic, but the blood eagle's voice became more and more excited.

Bang!

Behind many snake-necked tortoises, a relatively thin person seemed to have injuries on his legs, but was squeezed by other persons and fell to the ground.

After playing with these snake-necked tortoises, the bloody eagle flapped its wings and pounced down suddenly.

The strong wind brought by the waves made Lei Lin feel a little bit colored. As the blood eagle continued to decline, its body became larger and larger, far beyond the size of the snake-necked tortoise.

Originally, this size comparison was not very obvious at a high altitude, but now compared, the huge snake-necked tortoise in front of the bloody eagle was as big as a mouse.
