Under the combination of various favorable factors, Lin Fei's cultivation of the third level of the body quenching technique was simply not too easy.

And the third hurdle, that is, perseverance and perseverance!

When it comes to refining the muscles and bones, it requires perseverance and long-term perseverance that are difficult for ordinary people to achieve, and finally refining into steel, so that the muscles and bones of the whole body can be forged more and more powerful.

Different from ordinary exercises, once the body is cultivated, it is never-ending, constantly refining the physical body to the limit.

After the limit, there is the limit!

Keep breaking the limit, breaking the limit!

Only then can you refine yourself more and more powerful!

The cultivation of human beings is the same, constantly surpassing the limit, breaking through the limit, in order to make the current human race stand tall in the cosmic forest of the universe of all races!

Suddenly, a thought appeared in Lin Fei's mind.

"At the beginning, I devoured the mutated wolf genes to gain the alloy wolf claw ability, and then the wolf claw advanced to give me the ability to devour metal!"

"Since I can alienate my nails into alloy wolf claws, what will happen if the bones of my whole body are alienated into alloy bones?"

"Will my whole body bone be as hard as an alloy? Or even comparable to rune weapons? Or even beyond rune weapons? ”

After this bold idea flashed in Lin Fei's mind, it was like a bombshell being detonated, and it was out of control.

So, Lin Fei began to die!

"Open the wolf's claws!"

Lin Fei continued to devour the star stone in one hand, and began to devour the metal element after turning into an alloy wolf claw with the other hand.

It's just that in the process of devouring the metal element this time, Lin Fei has always maintained the operation of the quenching technique, and then his spiritual power has looked inward to probe the cultivation situation in his body.

He's going to do an experiment.

Verify your guess and see if it can be realized.

Perhaps, this is a loophole in the evolutionary system.

With a movement of his mind, a hot mutant bison corpse was brought out of the evolutionary space by Lin Fei.

"Devour!"

Lin Fei devoured silently in his heart.

The palm of the wolf claw in his right hand conjured up a dazzling light, quickly enveloping the huge body of the mutant bison.

In the blink of an eye, the mutant bison's body began to dry up rapidly, and it took less than ten seconds.

A mutated bison turned to powder and disappeared completely, leaving not even the bones and dregs left.

At this time, Lin Fei found that a large amount of energy matter disappeared along the palm of his right hand, and ninety percent of it was swallowed by the evolutionary space and disappeared inexplicably.

And less than one percent was absorbed by Lin Fei's body, and then after traveling all over the body, it was absorbed by various cells in the body.

A large number of impurities in it, in fact, in the process of devouring, had already been excreted from the body, and all the essence absorbed into Lin Fei's body was essence.

After the spiritual power continued to explore deeply, Lin Fei found that a large amount of energy matter in it poured directly into the palm bones of his hand and disappeared.

Among them, there is a large amount of energy matter that disappears inexplicably.

One source is the evolutionary space, and the other is the other, but Lin Fei didn't find out clearly.

At this moment, Lin Fei accidentally discovered that in the brain space, the golden World Tree sapling grew three golden leaves.

"The World Tree, actually growing another leaf?"

Before Lin Fei could be surprised by the changes in the World Tree, he was blinded by the evolution system again.

I saw that a line of system prompts appeared in Lin Fei's mind.

[Congratulations to the host for successfully discovering 1 system vulnerability, and the system reward: 1 piece of Eternal Pure Land, which can be used to transplant the World Tree.] 】

Ming: The host has successfully cultivated the World Tree seedlings, and after transplanting them into the evolutionary space, the World Tree will grow and develop better.

The Eternal Pure Land provides an infinite supply of eternal energy, contributing an inexhaustible source of energy and nutrients for growth and development to the World Tree.

In addition, when the World Tree is transplanted into the Evolution Space, a separate space can be created for the World Tree to grow and develop.

Lin Fei was a little confused.

He had just discovered a vulnerability in a system.

That is, in the process of cultivating the Quenching Formula, and at the same time operating the genetic ability of the system to devour, then the cultivation of the Quenching Formula will obtain an accelerated effect.

But in the process, it doesn't consume any evolution value.

But Lin Fei hadn't been happy for a second!

This loophole was patched in time by the evolution system, and when Lin Fei cultivated the Quenching Technique again, he found that the superimposed metal-devouring effect had disappeared.

It's so mysteriously gone!

This made Lin Fei very depressed.

"Holy! This evolutionary system is too unreasonable, isn't it? ”

"I won't even be given a chance to exploit the loopholes!"

"But what is this Eternal Pure Land? The system prompts me to transplant the World Tree to Evolutionary Space? Should I transplant or not? ”

Lin Fei was a little hesitant.

After thinking about it for a while, Lin Fei decided to give it a try and transplant it to the evolutionary space to see what changes there were.

Lin Fei couldn't hold back his curiosity.

"System, I'm going to transplant the World Tree to the evolutionary space!"

After Lin Fei issued the command, the system got a response.

[During the transplantation of the World Tree, please wait patiently, this transplantation process, there is no need to consume evolution value, it takes ten minutes. 】

Where the evolution space is, Lin Fei has always been curious.

This time, the transplantation process of the World Tree made Lin Fei feel the specific location of the evolutionary space.

In fact, it belongs to the same position as the brain space.

It's all between the eyebrows, but the evolutionary space was originally a void space, and now it has become a dimensional space after merging with Qingyun Ling.

It exists in the pronucleus of the gene at the same time as the brain domain space, but they belong to different dimensional spaces.

The brain space is like an organ in Lin Fei's body, and the evolutionary space is like an artificial organ implanted through surgery.

The relationship between the two, that's probably it.

Soon ten minutes passed.

In the brain space, the golden World Tree seedling turned into a golden ball of light and burrowed into the evolutionary space.

In the gray evolutionary space, a separate space was opened.

At this time, the seedlings of the World Tree exuded a golden halo slightly, like a miniature sun.

And beneath the roots of this golden tree of the world, a palm-sized piece of black soil appeared.

[Successfully transplant the World Tree seedling, Evolution Value is increased]

Variety: World Tree

Class: Unknown

Ming: The World Tree has many mysterious abilities, which can evolve the universe, create endless life, and evolve a world on its own.

Added: The World Tree Seedling fuses with the Eternal Pure Land to open the Gene Endowment [Huipu], which can absorb nutrients from biological corpses to condense the [Gene Fruit], and the corresponding Gene Endowment can be obtained by swallowing the Gene Fruit.

……

After seeing the system prompt, Lin Fei couldn't help but be pleasantly surprised.

"Gene Fu [Hui Pu] can absorb corpses to create [Gene Fruit], and after taking it, you can get the corresponding Gene Fu!"

"Na! How can such a thing happen!? ”

"Isn't that where I can have infinite genetic endowment?"
