It is an icosahedral pale golden crystal sphere with a faint translucent crystal on the outside, and the inner core gradually becomes a bit amber-like as you go deeper.

When he first saw this brain crystal, the first thing that came to Ian's mind was Scott's eyes, and the eyes of the Iron People squad leader were almost the color of yellow amber, but they were obviously not as big as the crystals.

At this moment, in front of the campfire, Ian picked up the huge crystal, thinking about how he should handle it and make it easy to carry.

The bonfire lit by the Braineater proves that there are actually plants around the hall, and it is not much different from the surface. The flame burns more steadily, and there is less smoke.

If they were alchemists, there would be such a fire, and it would be enough for them to process most of the materials, and Ian had not yet reached that point, and he had to have some professional equipment to assist him.

However, although he is not a master alchemist, he does not have instruments.

But he has a silver chip and an ancient dragon heart core!

At this time, Ian could sense that the ancient dragon heart core behind his heart began to gradually 'activate' when he came into close contact with the cerebral marrow crystals in a stable environment.

The heart core left by Teacher Hilliard is the sublimation organ of the fifth energy level 'authority level', and it is also the highest level and highest quality sublimation organ that Ian has seen so far, with Ian's current source quality, let alone using the heart core, it is difficult to even activate it.

The only way to use it is to use it as a warehouse for storing essentia, and for the past four years, the boy has been transferring the excess essentia he has refined to the core of the ancient dragon's heart, which is also a way to maximize the advantages of his ultra-high-quality source.

After all, for the general first energy level, even if Ian's essentia natural recovery and refining speed is two or three times that of theirs, the upper limit is so much, not really to the point of life and death, the gap between the two sides is not as big as imagined.

Especially the children of those great nobles, the food they eat is incomparable to even Ian, who has a prophetic vision, and is born to surpass ordinary sublimators in this regard, I don't know how many times, and the utilization rate of the source species is so high that dozens of percentage points can't catch up.

However, Ian has an organ that can be stored almost indefinitely, and that is too much to say.

By now, Ian had already stored all the essentia needed to create the first level of sublimation organ for Bai Jishuo, and was waiting for the recipe and potion.

However, even in the past four years, Ian has stored tens of thousands of basic units of essentia towards the heart core,

The Ancient Dragon's Heart Core didn't react either, just running warmly, which shouldn't have been theorized as Ian was physically exhausted and lacking essentia...... Because the strength that Hilliard retained back then was only around the peak of the second energy level, and there may have been a third at the beginning. The essentia of tens of thousands of basic units is enough to simply drive the heart nucleus to play the most basic function.

However, the heart core is still silent.

Until now.

"It seems that the core of Teacher Hilliard's heart was a little damaged back then...... When it was transferred to me, it was to prevent the excessive force of the heart core from draining me in an instant, so the teacher suppressed the power of the heart core, making its damage even more serious. ”

Closing his eyes, Ian scanned his body through the silver chip, although with his current strength, even with the silver chip, he couldn't get past the essentia structure of the ancient dragon's heart core.

But with the feedback of the gradually activated cardiac core, he can still roughly sense the current situation of this sublimation organ.

Ice Hell Ash is most likely a mesoscopic pure energy state structure of the same level as essentia, and it can even be said that it is a von Neumann machine composed of special essentia, which is extremely strong and extremely aimed at essentia structure, so for unsuspecting sublimators, it is almost the most vicious poison that is almost nirvana.

To put it simply, it is an offensive nanobot in the essentia state, but Hilliard, with his extremely superb essentia control ability, with the assistance of the silver chip, suppressed the Ice Hell before all the essentia organs were devoured, so that he not only did not die completely devoured, but could maintain a certain combat effectiveness.

But even so, when the heart nucleus was caught off guard, it was also damaged to a certain extent, and the subsequent metastasis aggravated this damage.

This is the reason why the ancient dragon heart core has been unable to respond to Ian for four years.

It needs to be fixed.

"The brain marrow crystals of the crocodile can repair the heart core of the ancient dragon to a certain extent?"

Sensing the activation of the heart core and the desire for crystals, Ian realized: "It's not difficult to choose a second-level potion material, if you can repair part of the heart core, it will be its glory."

"But here's the problem...... How do I absorb brain marrow crystals? Is it true that you can't stutter? ”

The boy frowned, lowered his eyes, and saw that the color of the brain marrow crystals was actually a bit like maltose, but this thing was not real sugar, and the hardness was comparable to metal, although his teeth were indeed good enough to chew metal...... But this thing is so big, he can't fit it in his stomach at all.

Unable to think of a solution for a while, Ian can only search for a possible solution in the silver chip... Bi Jing was a layman like Hilliard back then, who could use silver chips to perform alchemy without equipment, and as an alchemist with an almost official title, maybe there was an easier way?

And it turned out to be true!

The database of silver chips was full of strange things, from eleven recipes for stir-frying meat with chili peppers and conch, to tips on how to make nitrate and transplant rice, but there was no encyclopedia for Ian to search.

Only when he needs it, can he mobilize it from the chip like a 'memory'.

Now, the solution that Ian has mobilized from the silver chip is a technique called 'Blood Refining', which is an alchemy technique that can use the creature's own bodily fluids to 'purify and compress' Warcraft materials.

Blood refining, to put it simply, is to replace the original Warcraft materials with your own blood and store the essentia structure.

The only difficulty that can greatly reduce the difficulty of subsequent absorption is that this technique is very complex to control, and it needs to be multi-purpose, and the essentia structure needs to be adjusted in order to exert a perfect effect.

But the last thing Ian fears is so-called complexity.

Not to mention, he is already superior to ordinary people in this regard.

With the aid of the silver chip, he can perfectly reproduce the best effects of the blood forge.

“… This doesn't seem to be a method of alchemy for humans, but rather a method for krakens, water dragons, or slimes that have a lot of bodily fluids. ”

After pondering for a while, Ian recalled the technique of the silver chip in his mind, and after taking it to heart, he raised his hand with a frown, and used his fingernails to cut a bloody hole at his wrist.

With the support of the essentia of the sand armor apprentice, Ian's nails are as sharp as a monosilicon knife, and his wrists are astringent essentia, and the hardness is not too exaggerated tick, tick. Blood with a slight blue-gold sheen dripped on the brain marrow crystals,

Seeing that the blood flow was too slow, Ian frowned, made another incision, and controlled the blood flow in his body, and more blood was poured on the brain crystal.

With the assistance of the silver chip, Ian manipulated his essentia to transform its form to meet the requirements of 'blood refining, and his blood was like sulfuric acid, easily 'corroding' the crystals, bringing up large swaths of golden mist.

Ian sensed that these golden mist were the purest earth-attribute essentia, and he took a deep breath to inhale these essentia mist into his body and transfer it to the heart core for storage.

The taste is a little creamy and sweet...... But more of it was the smell of his own blood, and at the same time, his blood was still flowing out, 'corroding' the crystals smaller and smaller.

Eventually, the skull-sized brain marrow crystals were left with only a nucleus of amber crystals about two fingers wide, and a mass of 'blood jelly' that had turned golden.
