"This particular animal feeds on plant leaves, and its manure is an excellent fertilizer and hormone that stimulates the plant to grow rapidly and supply its needs......"

"And these plants and animals constitute the bottom ...... of all the food chains in the biosphere."

This is the only way to explain why the cycle in the biosphere can last so long. ＠，

After all, this is just an ecological laboratory, not a huge resource-based secret land, although the area is large, but it is not enough to support an ecological circle.

Now it seems that without the supply of outside experimenters, the creatures here have evolved their own unique ecosystems.

"Moo Moo ......"

At this time, a low creature roar was heard.

Leylin immediately hid his figure and looked at the approaching species.

It is a plesiosaur-like creature, but it also has a huge black carapace on its back, and barbs with cold light are densely covered on it, and it has an indestructible feeling when you look at it.

Its head is very small relative to its body, with two short protrusions at the back of its head, and a long snout, from which the cry just now emanated, with a heavy trill.

Bang!

The creature weighs no less, at least three tons, and the ground shakes slightly with each step.

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

And on the edge of the leaf that it had eaten, there were traces similar to the bite marks that Lei Lin had seen before.

"Chip! Compare databases!"

Leylin commanded secretly.

"Ding! mission is established, and scanning imaging begins. In the comparison database...... "The chip faithfully executed Leylin's orders, and the answer was almost instantaneous.

"There are no images of this creature in the database. Begin to look for the one with the highest similarity for comparison......"

The sound of chip machinery sounded.

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

Subsequently, the chip gave specific information about the snake-necked tortoise.

"The snake-necked tortoise: an ancient creature, now extinct, omnivore, with a mild temper and an astonishing defensive possessor of a carapace on its back, which is the ingredient for many defensive witchcraft. When it reaches adulthood, the snake-necked tortoise has the strength of a second-level wizard. ”

Leylin looked closely at the image of a snake-necked tortoise given by the chip, which was an illustration from an ancient book recorded by the chip, which had been kept in the database.

"Well, the difference between this creature and the snake-necked tortoise is that the carapace on its back is different in color, and there are some barbs, and the head is also a little different, so it should have undergone some kind of mutation......

Lei Lin is not surprised by this, under this ecological environment, the ancient species that do not actively evolve are probably extinct long ago. It's normal to mutate a little, maybe there is also the secret push of those quicksand members.

On the contrary, it would be abnormal if the ecological signs could be maintained in the same way as in antiquity.

"In that case, let's call you the plesio-necked tortoise!" Leylin decided. Anyway, the snake-necked tortoise outside has long been extinct, and there is no right to protest.

"Moo......" At this time, the snake-necked tortoise on the side never found Thunderlin. But he had already finished eating, and he roared a few times. Just get out of here.

Lei Lin's heart moved, and he secretly followed him.

"Shadows lurk!" though it's only a first-level witchcraft. But under Lei Lin's manipulation, especially with the promotion of the spiritual power of gasification, the effect exerted is still above many second-level witchcraft.

Leylin's body fell into the shadow crack, and even crawled directly onto the back of the snake-necked tortoise.

The solid carapace was very stable to step on, giving a sense of security, and Leylin looked around, surrounded by broad leaves and huge trees, and the vines hung down like numerous tassels. Huge droplets of water, rolling on the leaves and vines, exuding a mesmerizing brilliance.

And many flower buds larger than ordinary people are in full bloom, the colors are extremely bright, and there are all kinds of sweet flavors, which are tempting and dangerous.

Lei Lin's nose twitched: "Psychedelic pollen, and this kind of fluctuation similar to spiritual suggestion, I'm afraid that even a third-class apprentice or even a formal wizard will come over, and if you are not careful, you will be tricked......"

The feeling given to Thunderlin here is like the primeval rainforest in the previous life, with extremely abundant species and a primitive atmosphere.

The plesbill-necked tortoise apparently did not notice Leylin on his back, but did his duty as a vehicle well, carrying Leylin forward.

Its steps were very steady, and Leylin on his back did not feel a single jolt, and after about half an hour, the snake-necked tortoise carried Leylin to a lake.

Next to the lake is a clearing, and in the upper reaches of the lake, a white jade belt flows slowly into the lake, bringing fresh water to the lake.

"Moo Moo ......"

Here, a large number of plesmal tortoises gather together to form a huge group, and many plesmal tortoises swim happily in the lake, and from time to time they also dive into the water, suddenly popping their heads, making a huge splash, and at the same time spewing out two water columns from the inside of their noses, like fountains.

The plesio-necked tortoise that Leylin was riding also seemed very excited and crawled towards the lake.

"That's about seventy-five snake-necked tortoises!" Leylin's eyes flashed.

The snake-necked tortoise was not very famous in ancient times, not only was its own strength weak, but it also did not have any strong bloodline in its body, so it was completely useless to Lei Lin.

But they have one advantage, very high fecundity!

The estrus period of normal snake-necked tortoises is very long, and in estrus, they can lay nearly 100 turtle eggs every other month, and the survival rate of turtle eggs is also relatively high.

"This is the law of the biological world, powerful organisms are difficult to reproduce, and even if they give birth to offspring, it is difficult to feed, while low-level organisms are the opposite, and their fecundity and activity are incredibly vigorous......

Leylin suddenly thought of the rats in his previous life, the fecundity and adaptability of this creature can be called metamorphosed, and even if there is a nuclear winter, they are the animals that have the best chance of surviving.

"And the mutant snake-necked tortoises here, I can feel that the life activities in their bodies are more intense, and it is estimated that it will only take less than a year from the turtle egg to adult......"

Leylin touched his chin, it was obvious that for the survival of the race, the fecundity of these mutant snake-necked tortoises had been strengthened, which was also their acquired choice.

From these evolutionary choices, it can be seen that the plesmal-necked tortoise is definitely not a top-level existence in this ecosystem, but the lowest food chain, the existence of prey.

"Chirp!"

Just as Leylin was about to get some of the snake-necked tortoise's blood back to see what he could find, an eagle's cry came from afar.

It's a high-pitched sound with a very powerful penetrating power.

The numerous plesmal-necked tortoises stirred up and rushed towards the lake, and the same kind of people in the lake dived deep into the bottom of the lake, never to be seen again.

The screams grew louder and louder, and with Lei Lin's strengthened physical fitness several times, he could already see a streak of blood shooting from the distant sky.

It was a huge eagle-like creature, with hard, smooth feathers and a blood-red color, and a few strange clusters of golden feathers on the top of its head, forming the shape of a crown.

"Blood Vulture!Ancient creatures, with sonic attacks, can manipulate the blood in the target's body, and have a very strong interest in various precious bloodline items, and are ethnic creatures. Evaluation: Extremely dangerous!"

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

"Blood vulture!?" Thunderlin's face flashed with surprise, and then turned to joy.

"This creature has an unimaginable sensitivity to those unusual bloodlines, and has high-altitude vision, and can even see a hair on its face clearly at an altitude of more than 10,000 feet, and is often kept in captivity by ancient warlocks to find some bloodline treasures!"

"It's just ......" Looking at the extremely dangerous strength evaluation given by the chip at the end, Lei Lin hesitated a little again.

This blood vulture alone exudes a powerful power that Lei Lin does not dare to ignore, and according to the level of human beings, it has entered at least the third-level realm.

Moreover, the chip made it very clear that this blood vulture is a group creature, and there must be many third-level members in its lair, and there are even the kings of the blood vultures! As the leader of the entire race, the blood vulture king is definitely a third-level crystallized existence, even if it has reached the fourth-level Morning Star realm, it is very likely!

"Chirp!" the blood vulture circled in the sky, occasionally letting out a few cries, causing the snake-necked tortoise on the ground to panic, but the blood vulture's voice became more and more excited.

Syllable!

Behind the crowd of snake-necked tortoises, a thin man of his own kind, who appeared to have a wound in the leg, was squeezed by the other kind, and fell to the ground.

After enough of the snake-necked tortoises, the blood vulture flapped its wings and swooped down.

The strong wind alone caused Leylin to change color a little, and as the vulture continued to decline, its size became larger and larger, far beyond the size of the snake-necked tortoise.

Originally, the contrast between body shapes and sizes was not very obvious in the sky, but now when compared to it, the huge snake-necked tortoise was the size of a mouse in front of the blood vulture.

"Chirp!" the blood vulture stretched out its huge claws and cut a large hole directly in the neck of the fallen snake-necked tortoise, and the blood flowed straight down! (To be continued......)
