Lux felt that this 'Zhi Brain' was mocking himself, although in fact this was just a self-delusion born of Lux's shame, and there was no emotional fluctuation in Zhi Brain's tone from beginning to end, including 'mockery', and the aloud inquiry just now was just a kind of service attitude of it.

"No need!" After tugging at the corners of his mouth, Lux rejected Zhi Brain's proposal, and then packed what he had just made in a transparent box, and glanced at the standard sample next to him.

According to the description of the information given to him by Jiang Yan, the circuit material of this "Mantra Engraving" is called "Essence Crystal", which exists in a semi-solid form similar to nephrite spar under normal conditions, and looks comparable to some artificial gems and crystals, and the more beautiful and pure the color, the better the quality!

However, Lux looked at the "marrow crystal" he had made...... Not to mention the muddy and mottled condition, the color alone is very different from the description, especially when compared with the standard sample next to it.

Judging from the appearance of the two, the difference between the advantages and disadvantages of the two is very obvious.

But Lux still planned to test it, even if he had already made a judgment in his heart, he had to collect the specific data of the trial.

At least according to the information, Lux feels that his trial work is not a complete failure, but it is difficult to say how many achievements the specific effect can be compared to the original.

"Doctor, are you planning to use these 'Essence Crystals' now?" Seeing Lux's intentions, Zhi Brain reminded in a loud voice, "Then, please don't forget to prepare another 'Living Essence Potion'. 』

Lux was stunned when he heard this, he was already immersed in the quality of the trial work, and he might really forget about it.

Fortunately, compared to the complex process of "Essence Crystal", the production technology of the 'Living Pulp Potion' is not so demanding, and the raw materials are not very rare, and Lux did not spend too much time to make another palm-sized bottle.

The crafting of this potion may be a bit difficult for the average alchemist, but Lux is quite easy to make. Probably because of this, Jiang Yan simply didn't give away the potion sample before, and directly threw it to him after the formula ended the transaction.

After observing the color of this potion, Lux finally showed a satisfied smile this time, and sure enough, his skill level had not regressed!

Putting the potion in his pocket, and taking two boxes of "marrow crystals" with different characteristics and the soul crystals containing the brain, Lux left his own laboratory and went to an indoor testing hall that was already free, and called in a few trusted assistants to help him.

Anyway, the boy's transaction only said that the information should not be leaked, but it is not okay if he didn't say the finished product, right? With this in mind, Lux arranged a test plan for the "Myeloid Crystal" with peace of mind.

First of all, Lukes asked his assistants to bring a death row test subject, and under the frightened eyes of the test subject, he was drugged and sent to the operating table, and set up the equipment for observation.

Then, he cut off the subject's sleeve to expose his entire arm, took out the prototype "Marrow Crystal", and then took out a small bottle containing the "Living Marrow Potion".

Gently pouring the mouth of the bottle, the strange liquid in the bottle, which was as clear as boiled water, but there were a little pale cyan light chips floating inside, dripped onto the "myelin" below with the traction of gravity, and the liquid medicine penetrated directly from the surface of the myelin crystal in an instant.

As the liquid continued to drip in, the whole piece of the turbid yellow test piece began to be covered with a faint layer of verdant fluorescence, and the overall texture began to become much more transparent, looking like a softened and glowing turbid yellow jelly. Seeing this, Lux stopped pouring the liquid and put away the missing one-third of the amount of the living marrow potion.

"Crystal" is a solidified crystal when it is first made, which is convenient for long-term storage and is also conducive to commercial transactions, and as long as it is properly stored in a suitable container, the quality of the crystal will not deteriorate too quickly over time, which is equivalent to dormancy.

However, this dormant state of solidified crystals is obviously not suitable for transplanting into the human body and shaping the 'artificial meridians (marking circuits)', so if you want to use the 'myelin crystal', you must first turn it into an 'activated' state.

For this reason, Jiang Yan's subordinates specially designed the same thing as the 'Living Marrow Potion'.

The "myeloid crystal" that is activated has a very interesting property.

Just like now, Lux looked at the turbid yellow "marrow crystal" that had been activated by himself, he bent the corners of his mouth with some anticipation, and then raised the cleaned palm, and a spiritual light came out from his palm and pressed it on the marrow crystal, which was softened like jelly.

With the infusion of spiritual power, the fluorescence emitted by the entire ball of marrow crystals lit up slightly, as if it had 'lived', and it squirmed like a liquid creature like a slime!

Then, under the terrifying gaze of the surrounding assistants, the 'turbid yellow slime' actually squirmed and divided into more than half of its 'body', crawled directly to the hand of the experimental subject lying on the operating table, and finally pounced on his arm!

Silently, the slime's body was like water dripping into a sponge, quickly penetrating into his arm at a speed visible to the naked eye. During this time, the layer of skin on the subject's arm was almost non-existent, and did not cause any barrier to it.

Even after the medulla crystal penetrated, the subject's arm did not bulge in any way, but under the skin of his arm, a layer of blue and yellow light could be clearly seen spreading from the point where the medullary crystal had penetrated.

"It's ......!!" the assistants who watched all this almost exclaimed, but fortunately they still knew the measure, and after looking at Lukes's serious face, they still suppressed their emotions, and then silently watched curiously and apprehensively.

Lux didn't bother to pay attention to the reaction of his assistants, by this time he was completely immersed in the operation of the "Crystal of the Crystal".

'Interesting!' After activation, when spiritual power is injected, does it actually become this strange substance between the 'entity' and the 'spirit'? Because it has the permeable nature of the free energy state of the 'spirit', it is not blocked by the flesh and blood at all? But because it has the nature of 'entity', it can also form a stable structure......

After infusing the activated "marrow crystal" with his spiritual power, Lux found that he was able to freely manipulate the marrow crystal to carry out various shaping changes with his mind, and the feeling was somewhat similar to the touch he felt when controlling his own spiritual power.

As long as the manipulation ability is sufficient, then he can construct this mass of myelin crystals into any form he wants at will! The circuit formation of a specific magic array, or the structure of the 'artificial meridians' is fine.

However, compared to the real sense of freedom and smoothness when directly controlling his own spiritual power, Lux felt that he had a little more difficulty when he controlled this "marrow crystal", and the difference between the two was as obvious as the difference between waving his hand in the air and waving it in the mud.

'Is it normal?' Lux was a little concerned about the difference.

However, it didn't seem to be the time for him to dwell too much on this discrepancy, because Lux soon discovered that as the minutes and seconds passed, the nature of the myelin crystals that he had completely injected into the subject's body was gradually changing!

The sense of control that is like an arm is fading little by little, and this medullary crystal seems to be moving from a highly 'activated' state like a creature to a 'stable'!

Lukes, who had read the information, knew that this was a manifestation of the embryo shape of the original initial state of the medullary crystal, which was tending to 'solidify and mature'. If he continued to wait like this, he would soon no longer be able to change the medullary crystal's form as casually as he did now.

This is also normal, after all, the original intention of the myelin crystal is to build an artificial energy conduction circuit similar to the 'artificial meridians' inside the human body, and it is inevitable that it will eventually stabilize according to a certain morphological structure, otherwise how can it supply energy stably and circulate?

Of course, this 'stable' state of the circuit formed by the medullary crystal is only relative, and it does not mean that the circuit will become completely hard, but it will be synchronized with the flesh and blood body as the carrier in the same position, and it looks like the nerve veins of the human body, with a certain degree of elasticity, but it will not be easily separated from the flesh and blood.

Therefore, if Lux still wants to test the specific effect of this ball of marrow crystals he made, he must now complete the engraving circuit he wants before the marrow crystals are completely stabilized!

However, the process is not too easy.

Skin, flesh, bones, internal organs, nerves, and even blood vessels ......! Although these things inside the human body have more or less caused some obstacles to the activities of the myelin crystals in their bodies, of course, this is not insurmountable, but it is not as easy and casual as when directly driving spiritual power.

Fortunately, as a doctor of the empire and a top-level researcher, Lukes is also a point he is proud of in micro-manipulation control, so it is not too difficult for him to complete this kind of shaping.

But what he was more concerned about at this time was another thing: 'The time point when this began to solidify seems to be a bit too fast, much earlier than the time recorded in the information given by Yan Xiaozi......

However, the accelerated solidification of the medulla crystals inside the subject's body gave him no time to think about the reason for this difference, and Lux could only distract from his distracting thoughts, concentrate his mental tendencies and spiritual power to manipulate the medullary crystals, and devote himself to shaping the circuit structure he had preconceived.

Here Lux also has to thank Jiang Yan, that kid also came with a design of the "Little Fireball Technique" spell engraving circuit model when trading, although this technique is very low-level, and the power can only ignite a wooden barrel at most, but it is completely enough for this test occasion.

The technique is low-level, and the circuit structure of the spell engraving can be relatively simpler, which greatly reduces the difficulty of Lux's shaping at this time.

After a minute, the alien aura emanating from the subject's body dimmed, and the marrow crystals in his body completely stabilized.

Seeing this, Lux withdrew his spiritual power and secretly breathed a sigh of relief: "It's okay, it's not in vain." ”

According to the information given by Jiang Yan, Lux knew that after this kind of marrow crystal had undergone an activation of the 'Living Marrow Potion', it could only be used for one circuit shaping, and then it would be completely stabilized and could not be activated again to modify the structure.

In other words, the activated marrow crystal only has one chance to be used to build the marking circuit, and if Lux didn't complete the engraving circuit he wanted in time just now, then the ball of the marrow crystal he made himself would be wasted!

After secretly rejoicing for a while, Lux instructed his assistants to take good care of the test subject, while he went to check the experimental data recorded by the instrument just now, and checked the status of the imprint circuit in the test subject's body through the specially prepared instrument that could observe the inside of the human body.

Well, it did stabilize and didn't have any rejection from the flesh...... Oh, I see, although the structure is solidified, does it still maintain a semi-energetic nature state, and the energy attribute is also relatively peaceful and stable?, so the flesh and blood activities of normal creatures will not be adversely affected by this marking circuit......

Of course, the bad points are not without it, Lux found that after careful observation, the quality of the marking circuit in the subject's body seems to be a little fragile, probably unable to withstand too strong energy transmission, although the attributes are peaceful but with some mixed appearances, he has some conjectures in his heart, just waiting for the actual verification later.

It didn't take long to wait, and the subject quickly regained consciousness after the effects of the drug had passed.

Under Lux's coercive orders, the subject felt a little more strange in his body, but obediently complied.

This test subject is a rookie-level elven magician who has been selected by Lux with very weak strength but has a lot of experience in spiritual power cultivation, so it is not a problem to use spiritual power to perceive and control himself.

According to Lux's instructions, after he was surprised to find the extra marking circuit in his body, he injected his spiritual power into the circuit of the "Little Fireball Technique" implanted in his arm with apprehension and a little surprise.

With a snort, a pale red aura flickered, no magic array appeared, and less than a second of time passed, a fireball the size of an orange fist emerged from the palm of the subject, and under the control of his mind, it crossed an arc and landed on a humanoid wooden target ten meters away.

With a smack, the wooden target was ignited.

Seeing this, the subject's face was obviously surprised, and the assistants around him were also amazed and happy, but only Lukes, whose face was not very good-looking at this time.

Because, Lux originally thought that the target would be directly shattered, but now the target was only ignited, and only one-third of the target's body was ignited at one time.

"Although I have expected it for a long time, but sure enough, the real test is still a lot worse than expected...... "I want to talk about "The Almighty Supreme of All Worlds" with more like-minded people, and pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
