The storm outside the window was fading, and the terrifying hurricane began to turn as it hit the mountains.

The wind speed has weakened, but the rain has become more and more unbelievable, as if the wind that was enough to lift half of the South China Sea into the air has left, and the sea water that had been suspended in the sky has reverted to the earth and the sea.

It was as if a meteorite had fallen, and large chunks of water had smashed on the ground and rooftops, shaking the stone houses slightly.

"It's ......"

Inside, squinting his eyes, Hilliard took off his dry coat, he raised his hand, the golden essentia glowed, and then his palm slapped casually against the wall of the house.

In an instant, the moaning house suddenly stopped shaking, and the sound of the wind and rain outside became much smaller, as if it had been weakened by layers of walls.

"It's extraordinary."

Hilliard came to Ian's side, he leaned down, carefully observed the crystallized flesh in the boy's hand, and couldn't help but praise from the bottom of his heart: "This is really a good thing, the essentia thymus fragment of the second-level peak demonic beast...... Ian, how did you get there? If it weren't for a serious injury that was almost fatal, it would never have been possible to knock out the thymus of a demonic beast! ”

"Thymus?" Hearing the teacher say the crystallized flesh and blood in his hand, Ian couldn't help but be a little surprised, he lowered his head, stared at the blue and red flesh on the table, and sighed in surprise: "This is too big!" ”

The thymus gland is generally located below the thyroid gland, which is a fragile lamellar tissue, it is the earliest mature immune organ in most organisms, and it is generally not very large, such as the thymus in Ian's hand, which weighs at least a few kilograms, and only the giant monster of the totem main crocodile can be produced.

The main function of the thymus gland is to produce hormones, catalyze hematopoietic stem cells into primitive T cells (a type of immune cell), which is a very important part of the biological immune system.

"That's right."

Ian pondered his vocabulary and went to the tower, where he fired the alchemy cannon with the help of the garrison guards and helped Viscount Grant repel the crocodile to Hilliard: "It's not enough to die, but I think the cannonball must have been in the crocodile lung." ”

“…… Will you aim and fire artillery? ”

After listening, Hilliard's expression became subtle.

He frowned, looked at Ian, and said in disbelief, "Didn't you say that you didn't personally operate and repair the alchemy cannon at Elder Pud's?" ”

"The first time you actually operate, how dare you take a risk!"

- Is it difficult? Aim, ignite and launch, monkeys will use it.

Although he thought so in his mind, Ian just said honestly: "Maybe I'm smarter, and I'll be able to see it?" ”

"If you have seen it, if you have used it, if you hit it, you will be the best of the best-how can you brag with that group of old **."

Shaking his head slightly, originally, the old knight wanted to reprimand Ian.

This kid doesn't look at how many catties and taels he has, so he dares to open fire and face a big demonic beast that is at the peak of the second energy level and has a great probability of being able to advance to the third energy level?

It's a tactful to say that he is not afraid of death, he didn't have such courage at the beginning!

Although he was very angry, seeing Ian's well-behaved and sensible expression at this moment, sitting upright, and looking at him expectantly, Hilliard couldn't get angry again, and just sighed.

"Forget it, you won anyway."

He reached out and rubbed the boy's hair fiercely: "I guess, you also know the consequences of your actions, but just make your own judgment. ”

"But remember, if it's really an invincible situation, running away is the real choice that requires courage."

After the boy whispered yes, Hilliard let go of his hand, and he sat down at the table and began to examine Ian's loot in further detail.

"The swamp crocodile is extremely immune, almost ignoring most natural toxins and diseases, and its thymus hormone induces the maturation of several different powerful immune cells, especially against parasites and miasma in the tropics."

While inspecting, Hilliard explained to Ian: "These are just the basics, when you reach the second energy level, the crocodile's thymus gland will be transformed into a complete sublimation organ, and it will gradually transform into this crystal flesh tissue in your hand. ”

"At that time, it can not only regulate immunity, but also interact with the heart, modify the composition of the blood, make it have a certain ability to disinfect, and at the same time, it can also greatly speed up the speed of wound healing."

"This crocodile is close to the third energy level, and his internal organs are condensing the 'phase element structure', and the phase structure in this thymus is very complete, this is your biggest gain this time!"

"How ...... that" Surveying the blue-red flesh on the table, Ian thought of the orange-red blood splattered from under the scales when the crocodile invaded Port Harrison and was hit by artillery.

Indeed, that small wound healed quickly.

Even, even his own critical shot, and Viscount Grant's sword that almost cut off its midfoot, did not cause it to lose too much blood and affect its ability to escape.

And the mud shield that covered the crocodile's whole body was incredibly powerful, and even the electric cannon, which could shoot out supersonic shells, could not completely break through the defenses.

As for the cells and hormones that appear in the teacher's mouth......

With the level of technology that the continent of Terra is showing today, it is strange that Hilliard does not know about cells and hormones.

In particular, sublimators, which are obviously very related to the level of biotechnology, are even likely to involve deep genetic modification.

"Well, it can be used as the main ingredient for your future potion."

In the end, Hilliard made a judgment: "The Swamp Crocodile is an earth-type magical beast with certain water attribute characteristics, and its talent 'Fertile Earth Body' needs to control the essentia of both water and soil at the same time, otherwise, it will not be able to control the mud as its own shield, which is just a cover for your 'Legacy of the Wavefarer'." ”

"Although it is a bit overkill for ordinary sublimators to use the materials of the peak of the second energy level as the base of the first energy level, if you really want to go down the path of 'Immovable Strong City', such extra efforts are necessary."

The more powerful it is, the more expensive it is.

Turning his head to look at Ian, the old knight was half telling, half admonishing: "And as compensation for the price, you can make your essentia have obvious attributes when you are at the first energy level. ”

"It's a benefit, it's a risk, if you're not a psyker, and you're just a civilian, I won't let you take this extreme path."

Essentia also has different properties.

Just as human beings live in different regions and have different signs, life itself is different, so the essentia extracted by each person is naturally different.

——In the ancient mythology of Terra, the breath, soul, flesh and blood of the Heavenly Father are transformed into the four heavens and four directions, and the four heavens are intertwined and entangled, constructing a thousand winds and suns, the earth and the sea under the sky, which is the origin of the four genera of wind, fire, earth and water, the four seasons of spring, summer, autumn and winter, and the four states of qi and solid-liquid.

The essentia of different attributes has different aspects of strengthening the human body, focusing on endurance and body strength, water is biased towards regeneration and life extension, wind is good at self-amplification and unloading, and fire has the most diverse explosive power and means of destruction, but it is also the most unstable.

Ian himself is still young and doesn't often go out to work, so he is not subtly affected by the environment, but after all, he has lived by the sea for nearly ten years, and his original essency is biased towards water and wind.

Therefore, after refining the essentia, the injuries on his body healed quickly, and he was able to increase his strength.

However, attributes are not innate, nor are they absolute.

If Ian now settles next to the volcano, eats local food, and breathes volcanic haze, it won't take a few months for his natural essentia to transform into fire and earth.

Rather than natural tendencies, people's own choices are more important—rather, aren't people's innate attributes also dependent on the choices of their parents?

"Is it obvious that the attribute essentia...... It's powerful, but it's also dangerous. ”

Ian has a deep memory of the sublimated common sense that Hilliard has taught him, and he knows the nature of 'attributes' very well.

That's the interaction with nature.

The Swamp Crocodile is a magical beast based on earth and water, and it will never leave the swampy area of the jungle area for the rest of its life, not only because it adapts to this environment, but also because it can only become stronger in such an environment.

It's like a crocodile that can fossilize into mud when it enters a city, turning rocks and mud into its own skin and shield—if it's in a swamp or deep in a mountain, how much more difficult should it be?

While changing the natural environment, it also makes yourself more adaptable to nature.

But on the other hand, if the crocodile goes to the sea and fights in snow-capped mountains and volcanic areas, it will exert three or four percent of its combat power at most, and after a long time, it will even starve to death because it cannot synthesize the special essentia needed for various sublimation organs in its body.

So even if they have to move, crocodiles will choose desert oases or areas such as mudflats along the beach...... If it can't be satisfied, even if it is lucky not to die, the bloodline will deteriorate, and the descendants will not be able to inherit the bloodline characteristics of the Warcraft, and gradually revert back to the ordinary beast crocodile.

If you use the crocodile material as the main material of the potion, Ian's essentia will be converted into the earth genus, so that her physical fitness will increase in all aspects, and she will have an advantage in the environment with dirt and rocks, and the essentia in her body will be more active.

That's where the attribute essentia comes in.

"The earth attribute is actually okay, after all, as long as you are on the planet, it is impossible to really break away from the earth."

Ian knew that risk comes with opportunity, and strength and cost coexist - attribute tendencies that should only appear at the second energy level can be mastered by him at the first energy level, which is naturally an excellent opportunity to train in advance.

In the future, he will advance to the second energy level, and he will be able to quickly master many skills that should have been honed for a long time, and he can speed up a lot compared to others.

But the first energy level is also far less resistant to the environment than the second energy level......

"It's a trade-off." Ian is well aware of this: "At most, stay away from the open sea." ”

Offshore is not a big problem, the Sand Armor Apprentice can reduce the rate of breathing, as long as it is not too deep and too far from land, even if they can't swim, they can walk all the way back to the shore from the bottom of the sea.

In a word.

The environment in Port Harrison isn't extremely harsh, but it's not safe either.

Not to mention, if he can have the ability to protect his body by calling for mud and sand after taking the potion, his safety and survival ability will be greatly enhanced.

"Leave it to me to deal with, your current alchemy level can't perfectly handle this level of Warcraft materials."

Hilliard slapped the table, and Ian naturally had no objections, rather, this was what he had in mind.

Dealing with the materials of a low-level magical beast like the Reef Devouring Sea Otter is naturally easy to use with his current level of alchemy, but it is unlikely that the Swamp Crocodile Dragon.

Mainly because he hasn't learned yet.

However, just as the old knight was about to put away the crocodile's crystallized thymus, Ian inadvertently looked up at his teacher's face and noticed that something was wrong.

"Wait, teacher......"

He stared straight into Hilliard's face, and Ian frowned, "The wrinkles on your face......"
