Ancient cataclysms, extinct creatures, countless.

Little is known about the cause of this cataclysm, except that the ancient creatures, known for their size and strength, were extinct in large numbers in a very short period of time.

According to the conclusions of the Corleone Institute for Biospecimen Research.

The so-called cataclysm refers to the drastic change of the ecological environment.

At the beginning of the cataclysm, due to the weak nature of the lower creatures, they were most directly affected by the drastic environmental changes, and they would die in large numbers in a very short time, while the higher creatures were able to survive the direct impact of the cataclysm by relying on their strong strength.

But.

Over time.

Weak creatures are more likely to mutate, and will complete their survival and evolution one after another, gradually adapt to the new environment, and reproduce and grow.

Powerful creatures, on the other hand, have difficulty adapting to changes in the environment, so they will become extinct in large numbers in a new environment.

As for the causes of extinction, they are varied.

Some of them are because the natural environment damages them all the time, which is similar to being repelled by the world's magnetic field, and then produces energy regurgitation and accumulation in the body.

Others die of hunger day after day because of lack of food.

After adapting to a new environment, the once inferior creatures often carry highly poisonous beings to the ancient creatures.

The extinction of the Optimus Tree is due to the collapse of its own ecosystem and the loss of its symbiotic partner!

The collapse of the ecosystem, well understood.

The second true body of the Supertree is attached to its ecosystem, and the will of the biological chain is similar to the miniature version of the laws of nature, and if it loses the biological chain, it also loses the ability of the secondary true body, and can only exist in the form of an ancient tree, unable to move.

As for the symbiotic partner, it is the herb ginseng elf!

Ancient times.

For many higher plant life, the status of the ginseng elf is equivalent to that of today's bees, spreading pollen.

These higher plants need a certain special energy of the Grass Ginseng Spirit to be able to complete the transformation of some special life energy, and then maintain their huge size or rare attributes.

It is precisely because of this that the herbaceous ginseng elves were able to rely on their insignificant strength to occupy a very important role in the ecosystem in ancient times, and were protected by many higher plant life.

However, the ancient cataclysm......

"It's the moon!"

Xiaobai recalled the past, with a touch of fear.

"Ever since the moon appeared, my people's skin has festered when they shine under the moon, not just my people, but many ancient creatures. And the natural energy seems to have been taken away by the moon and thinned, and the world's magnetic field has become unstable, and there are also changes in the tides, which have caused a lot of flooding, and the once beautiful coastline is full of corpses......"

In Xiaobai's description, the moon seems to have become a terrifying devil.

"In that catastrophe, although I was mutated, I also fell into a state of dehydration, and I didn't know anything about the outside. ”

The Tree of Truth held Xiaobai as if it were treating the most precious thing in the world.

Lei Luo became the foil of the two, quietly following behind them.

"I see. ”

The Tree of Truth stared at Xiaobai, and a hint of hope appeared on his green face.

"So, how do I complete the transformation according to the evolution of the Ancient Optimus Tree?"

This Tree of Truth, grafted by Bonnie Vince, has grown to the peak of the third level after nearly a thousand years of growth, and theoretically speaking, it only needs to complete symbiotic evolution and ecosystem construction to break through to the fourth level of existence.

"I don't know. ”

Xiaobai said embarrassedly: "Those things were done by my clan elders, and no one has taught me." ”

The Tree of Truth's expectant gaze was slightly dimmed.

"I have a feeling that if I can't complete the symbiotic evolution and complete the qualitative change, if I continue to grow like this, one day I will crush myself and die because of my own weight. ”

Unconsciously.

The three of them had come to the ground from the branches of the Tree of Truth on which they were riding.

Compared with the difficulty of climbing to the top of the tree before, the journey back is much easier.

Lei Luo looked up, and the Tree of Truth soared into the sky, submerging into the raging turbulence of the Dao.

He frowned and said, "Why didn't anyone find you a few days ago?"

"Normally, I release the psychedelic fog, and I will only cancel the fog on the tenth day of the assessment, and if I want to forcibly crack my fog, I need at least legendary creatures to have a chance. ”

The Tree of Truth explains a little.

Suddenly.

The earthquake trembled, and as the ground was raised, a thick tree root stretched out to reveal a hole in the ground.

"This is the first time that an outsider has visited my home, so I can only enter this way, if it is just me and Xiaobai, I only need to enter through my body. ”

Coming in from your body?

Lei Luo looked at the emerald green skin and slender figure walking in front, and his thoughts couldn't help but be evil and dirty for a moment, and then hurriedly chanted Lola's name, shook his head, and followed the two of them to the ground.

Distance.

"Oh my God, what's going on there!"

"Something seems to have come out of the ground, let's go see!"

However, as soon as these assessment students approached, the roots of the giant tree rolled and sank into the ground again, and the underground entrance that appeared briefly disappeared in the blink of an eye.

After a while.

"Hiss......"

Even with today's Lei Luo, he can't help but feel a touch of disbelief.

"This, that's what you call it, a piece of the root of the Optimus Tree!?"

At this moment, in front of Lei Luo's eyes, there was a vast star curtain world atmosphere, and Lei Luo could faintly see some elliptical arcs, and the atmosphere extended to the unknown in the darkness.

At his side, there was a huge fossil, like a starfall leyline.

In other words, the so-called assessment space nodes are just some of the land that evolved on the fossil root of this Optimus Tree.

And the so-called grafting is that Whiteney Vince placed a special seed in the center of this starfall, and that's it.

A single rhizome is so huge.

The true size of the Giant Tree, Lei Luo could have imagined it as he could.

"However, how did such a huge rhizome come to the heavens, and together with so many starfalls, it formed the current star curtain layer? I really can't imagine what happened to the ancient cataclysm!"

Not to mention the collection and study of specimens after the shock of Leilo.

Xiaobai became more and more intimate because of the instinctive symbiotic relationship with the Tree of Truth.

The night passed.

The trio gathered again.

Lei Luo said: "Although I don't know what is going on outside, according to the assessment regulations, in the early morning of the eleventh day, all students must leave the secret realm, and there will be construction personnel from the Finnish Academy behind them to maintain the facilities and prepare for next year's assessment." ”

It is not difficult to imagine what kind of anger the students who have left the secret realm will question the people outside.

But this has nothing to do with Relo.

Even, Lei Luo is grateful.

If it weren't for such a change, he would not have broken through the highest score in the history of the graduation assessment so easily.

The other side.

The Tree of Truth said: "Xiaobai is the key to my evolution, and I can't leave it, so I have two plans, can you consider it?"

Belch?

Lei Luo said slowly: "You say." ”

"The first plan, I hope you can keep Xiaobai by my side, the time is uncertain, it will be decades, or thousands of years, and I will give you enough wealth. ”

"No way. ”

Lei Luo immediately denied: "Xiaobai is my media partner, once a scholar loses his media partner, it is almost impossible to be promoted. ”

Lei Luo said this, but it was not absolute.

For ordinary scholars, it takes a lot of time to absorb the energy of nature after losing a media partner, so a lot of research time will be lost, but it is not absolute to say that there is no progress.

As for Lei Luo himself, because of the special astral evolution method, he has broken away from the dependence on the medium partner to absorb natural energy, and replaced the natural energy with special astral essence resources, forming another dependence.

Other than that.

In recent years, Barda Academy has carried out research on blood fusion, and many people are born with the ability to integrate into the world's magnetic field, and they can no longer rely on media partners to promote the level 1 energy magnetic field to integrate into the world's magnetic field, or into the magnetic field environment of the Land of Stars.

The Tree of Truth said slowly: "The second plan, I heard Xiaobai say, you want to set up a laboratory, I can open a special teleportation smuggling coordinate for you, and all the teleportation costs in the future will be borne by me." We can even complete a transaction, as long as you can help me complete the ecosystem construction, my second real body will permanently protect the safety of your laboratory, how about it?"

This proposal made Lei Luo very excited.

In terms of laboratory security, Lei Luo has Xiao Hei obtained on the fifth floor of the Sun and Moon Demon Eye Pyramid, but activating Xiao Hei requires a huge amount of energy source to allow him to exert his due strength.

At this stage, there is still a lack of sufficient energy sources.

And the key thing is that Xiao Hei can only protect some hidden experimental spaces that cannot be opened to the public.

And if the second true body of the Tree of Truth can come, in its current situation, it will at least be an ancient creature-level existence!

"All the smuggling energy, you bear it?"

Lei Luo questioned: "This spatial node, the nearest coordinates are between the Duchy of Finland and the Duchy of Utolan, and my laboratory will be built in the territory of the Duchy of Gran, and the energy and Zero Boundary Stone crystals required for smuggling are not a small amount!"

"Rest assured. ”

The Tree of Truth said confidently, "I have enough reserves here for you to consume for hundreds of years. ”

After a brief moment of shock, Lei Luo's eyes suddenly lit up.

"Many large laboratories are divided into two parts, the surface layer and the inner layer, similar to the Corleone Institute of Biology, which is an ordinary biological specimen research institute on the surface, but in fact it is a laboratory for studying the evolution system of species and the theory of the civilization system of the Storm Continent, capturing those terrifying legendary creatures that travel on the continent through seals, and opening up a map of the Storm Continent in the secret laboratory. ”

"So, can you build this place into your own secret laboratory, and place some academic research in the starry sky that cannot be opened to the outside world?"

The more Lei Luo thought about it, the more he looked forward to it.

"Separately built as ...... Relo Institute of Solar Energy, and Lola's Secret Garden!"
