Controlling essence outside the body was a hundred times more difficult than inside the body. Especially to control such a large amount was an extremely difficult task for Oscar who had never used essence before.
At this time, Oscar's mental power had been activated to the maximum, and he was constantly controlling the output of his mental power.
That meant, he had memories of two lives, and his essence was different from ordinary refiner of essence.
After eight years of harnessing and refining ether, especially in the past two months, and after consuming some magical bugs every day, not only did his physique and power base improve, but his mental strength had also improved while greatly increasing his essence.
In the immortal cave, he could only see a vague shadow of his immediate environment by relying on the light of the magical bugs.
But with the daily consumption of the silkworms and the increase in his essence, Oscar was now able to reach the level of normal night vision.
This had nothing to do with the ability of his sight to adapt to the environment, but completely in the quality of his sight caused by the increase in his essence.
Under the control of hiss essence, the huge orb of essence kept shrinking, and finally a huge transparent crystal was formed in front of him.
Inside the crystal were a series of purple cloud patterns visible to the naked eyes. It was really beautiful in his eyes. So he continued to release his mental power.
Sweat had already wet a large part of his clothes, and more layers of sweat were still condensing on his immature and resolute face. It kept dripping from under his jaw as his brows were deeply furrowed, showing he was reaching his limit.
The huge essence crystal was still compressing continuously, which meant that he had an exceptionally strong aptitude, otherwise, after condensing the essence crystal, he would have completed the task of forming and compressing with little effort and be done with it.
Finally, when he felt that he was about to faint, he stopped releasing his mental power and slowly opened his eyes. He saw a small round crystal quietly suspended in front of him, emitting a faint energy.
But when he saw the color of his essence crystal, he frowned. Why was it black?
Oscar's crystal was totally strange to him, or to his new memory to be precise. From his newly acquired memory, his father once told himself that there were two types of essence crystals for refiners.
One was formed after harnessing ether during the day, and absorbing the energy of the sun. That was the transparent white crystal.
The other was formed after harnessing ether at night, and absorbing the energy of the moon to form an amethyst crystal. That was a rare transparent white crystal with a purple cloud pattern.
So, what did this black crystal that he formed mean? Alien crystal? Oscar was puzzled. He was not the only one bewildered, but the remnant was also surprised.
[This is newv to me]
In his limited but long memory waiting as a guardian, he had never heard of the existence of black crystals. In the historical records of the world, he doubted if such a thing had existed before.
After the young refiner and the ancient guardian communicated for a while, they both fell into contemplation.
Initially, when Oscar formed the unique essence crystal that was a little bigger than a fruit basket, the remnant was so surprised that he almost didn't help the boy to disperse his consciousness.
Realizing that Oscar's consciousness was unstable, the remnant immediately calmed himself down and consolidated his consciousness again.
Only then did he continue to monitor the situation of the essence crystals with an uneasy mood. In fact, it was no wonder that the remnant found it rare and strange. In his memory, essence crystals were supposed to be bigger than a moon stone at the least.
So, he continued to watch as Oscar's essence crystal continued to shrink, and finally it stopped at the size of an ostrich egg, and the color gradually deepened from transparent purple to purple, dark purple, and finally black.
The remnant's expression gradually turned from surprise to doubt.
After his analysis and research, the remnant did not find a reason whatsoever. In the end, he came to a conclusion.
[Beast Slayer, I think you must have used your powerful mental force as a transmigrator from another world to compress the essence crystal too small, so there was a qualitative change, making the black color appeared]
It was a unique essence crystal of the sacred body, but it was too compressed. After all, the unique essence crystal pattern appeared before it's form was finalized, and it only changed its color with continuous compression.
[You have already formed your essence crystal. Now, try to put the essence crystal into your soul space. Dissipate the essence in the middle, and then withdraw all the scattered essence particles into your soul space]
Oscar tried what the remnant told him, and certain enough, the essence was withdrawn into his soul space. It's just that the orb of essence in his soul space at this time had become very small, not as big as the nine orbs of essence that it was initially divided into.
Nonetheless, the sense of its solidity was extremely powerful.
[Now release your essence and turn it into a crystal in front of him. There's no need for you to compress the essence as hard as before. It will be easier for you to manifest a crystal]
Afterwards, Oscar tried several times, until his mental power was almost exhausted, and then he gave up. The creation and manifestation of the essence crystal had also become more permissible, hence the time spent was getting shorter and shorter.
[Stop here. Eat one worm to restore your strength before continuing]
An hour later, Oscar got up after realizing that his mental power had recovered a lot. But he stopped as a hint of surprise registered on his face.
He found out that in addition to the orb of essence in his soul space, there was a trace of essence that was constantly circling around in his body.
